Still another object of this invention is to pro
vide such a machine having a device by which
of a shoe such as, for instance, those which go to
the clamp may be regulated while at the work
receiving station.
Still another object of this invention is to
‘make an upper may consist of quite a number of
separate and individual parts which must be
united before the ?nished upper is ready for the
20 shoe forming operations, such as are well-known
in the art. For instance, under some circum
> stances, it is preferable to secure the various parts
of the upper, including the lining and doubler,
together by cement, such as securing the quarter
25 to the vamp, or securing an inlay such as is com
mon practice, especially in ladies’ shoes.
The provision of a suitable clamp for main
taining the various parts of a shoe upper in
their proper alinement during the setting of the
30 cement or glue involves not only the provision of
a device for adequately maintaining the parts
in their desired position, but also involves the
provision of such means as will have no tendency
to mar or deface the surfaces of the various upper
35 parts; it being realized that the leather or other
material employed in the uppers of shoes of this
provide a control mechanism for the machine of
this invention which is movable through various
zones to eifect, respectively, the regulation of
the clamps and the advancement of the machine.

In accordance with this invention, a suitable
carrier preferably in the nature of a rotatable
wheel is provided about its periphery with a
plurality of clamps, each of which is adapted to
receive a shoe upper after the various parts have
been placed in their proper alinement and
cemented. Any number of such clamps may be
provided about the carrier and are preferably
equally spaced therearound, it being understood
10 that the carrier may be of any desirable size so
as to accommodate the desired number of clamps.
Suitable mechanism is provided for moving the
carrier and stopping the same at a particular sta
tion to be designated hereinafter as the work re»
15 ceiving position. If the carrier takes the form of
a wheel, as in the illustrated embodiment of this
invention, suitable mechanism is preferably pro
vided for advancing the carrier through a sul?
cient angle to bring the next succeeding clamp
20 into the work receiving position.
Furthermore,
suitable mechanism is preferably provided for
opening the clamp as it approaches the work re
ceiving position, such mechanism being releasable
to permit the clamp to close, and in the illustrated
25 embodiment of this invention this mechanism is
effective to initiate movement of the carrier at
the same time that the clamp is released. More
over, it is often desirable that the clamp may be
regulated or opened several times while the oper~
30 ator is inserting the work therein, in order to
insure that the work is properly alined before
the full pressure of the clamp is applied to the
work, and accordingly, this invention contem
plates the provision of means for regulating the
35 position of the clamp and governing the applica
tion of pressure thereby while the carrier is at
rest and the particular clamp is in the work
receiving position.
'
Referring now to the drawings for a descrip
tion of an illustrative embodiment of this inven
tion, a suitable support comprising upright mem
bers l and horizontal members 2 is provided for
secured thereto. With the leg II and its adjunct
table l2 shaped and arranged as shown, it is
apparent that a completely closed shoe upper may
be draped thereover, as shown in the broken lines
at IUI in Figure 3. The upper leg 9 is provided
with a bore l4 for slidably receiving a cylindrical
shank l5. The shank I5 is provided with a ?ange
I6 at the upper end thereof, so disposed as to limit
the downward movement of the shank to a pre
determined position, as will be later described. 2. 0
The shank I5'carries at its opposite end, a head
I‘! which is provided on its bottom face with a
recessed portion I8 and is covered over with a
suitable diaphragm IQ of any ?exible material
such as, for instance, leather. The diaphragm I9
is secured to the head I'I around the edges thereof
by any suitable device such as, for instance, a ring
2 I, and suitable fastening elements such as screws
22. It is thus apparent that the recessed portion
I8 being covered over by an air-tight diaphragm 20
such as I9, forms an air chamber which upon the
application of pressure therewithin will cause the
diaphragm l3 to be expanded outwardly in the
direction of the table l2. A suitable connection
such as a nipple 23 is provided for connecting the 25
air chamber I8 with a source of air pressure and
a suitable intake valve such as 24 is provided
for controlling the admission of compressed air
to the air chamber. Likewise, an exhaust valve 25
of any suitable type is provided. The operation 30
of the respective valves will be more fully de
scribed hereinafter.
It is apparent that the shank [5 with the head
[1 is movable vertically through the bore M to
vary the distance between the head I‘! and the 35
table I 2, as illustrated in the dotted line, Figure 6.
Any suitable device may be provided for pre
venting relative rotation between the shank I5
and the bore I4, such as, for instance, a pin 26
provided at the rear of the head I‘! for coopera 40
tion with a groove 21 in the casting. On its up
per face, the head I1 is provided with a boss 28 for.
supporting the moving parts of the apparatus.
loosely receiving a pin 29, which latter is carried
Substantially‘ centrally of the upper horizontal
by a lever 3I. The lever 3| is journaled for rota
tion upon a pin 32 carried by the casting. It is
thus apparent that when the head I1 is moved
» member 2 a suitable bearing 3 is provided for the
reception of a shaft 4, which is rotatable therein.
A wheel 5 is mounted upon the shaft 4, and prefer
ably secured thereto for rotation therewith, as is
likewise a ratchet wheel 6. The ratchet wheel 6
is preferably sufficiently spaced from the wheel 5
to permit access to the operating mechanism and
is adapted to receive the driving force for the
vertically relative to the casting and between its
dotted and full line position illustrated in Figure
6, the lever 31 will pivot about pins 26 and 32.
A bell crank lever 33 is provided and preferably
rigidly secured to the pin 32, so that upon move
ment of the lever 33, the pin 32 is rotated within
its bearing in the casting. One arm of the bell
crank lever is provided with a knob 34, disposed
to engage and cooperate with a suitable clamp
regulating mechanism to be hereinafter more
with this invention, so that the wheel 5 may be fully described. The other leg of the bell crank
rotated to carry the respective clamps ‘I in a lever 33 is provided with a pin 35, extending in
circular path and past the work receiving and wardly therefrom and disposed to engage the
releasing position 8. The upper carried thereby > under surface of the lever 3| when the bell crank
is then released and another upper placed in the lever 33'is rotated in a clockwise direction. It is
clamp to be carried about the circular path, it thus apparent that when the bell crank lever 33
being understood that sufficient time is consumed is rotated sufficiently to bring the pin 35 in con

later described.
The wheel 5 is provided about its periphery with
a plurality of clamps ‘I, constructed in accordance

be pointed out that when the parts are in the
position illustrated in Figure 5, the exhaust valve
the zone a, near the dotted line position illus
25 is preferably in its closed position. A spring
53 of any suitable type is preferably provided for
biasing the lever 49 in a direction tending to open
the exhaust valve. For the purpose of illustra
tion, the spring 53 is shown as a contractile spring
anchored at one end 'to the head l'lp' and ‘engaging
at its other end the lever 49. It is thus apparent
that when the head I‘! with its adjunct parts has 10

Theishank I5‘ is provided at one side thereof
with an inclined slot 36 adapted to receive a
similarly'inclined portion 31 of 'a slidable bar
‘38. The bar 38 is mounted in suitable trunnions
‘39 ca'rried'by the casting. A spring 4| is provided
for-biasing the bar 38 toward the left as seen in
Figured. It is thus apparent that the spring 4|
is effective through the interaction of the inclined

extreme end of the lever 49 has been moved out
surface '3'! with the slot v36 to force the head i’?
of engagement with the cam 44, the ‘spring 53 will
then operate to close the intake valve 24 and
maintain the exhaust valve 25 in its open position.
It may here be pointed out that the arrange
merit of the various operating parts in the illus
trative embodiment, illustrated in the drawings,
downwardly. The inclination of the portion 31,
however, is preferably such that sufficient fric
tion is present to prevent the movement of the
'bar 38 toward the left upon application of a
force upwardly against the head ll, so that the
‘portion 31 cooperating with the slot 36 forms in
20 effect a latch for maintaining the head l‘! in its
lowermost position and‘to prevent upward move
ment thereof in consequence to the application of
a pressure tending to force the head I‘! upwardly.
The bell crank lever 33 is provided with a suit
able ‘lug 42 disposed in such position that it wiil
is such that a substantial movement of the bell
crank lever 33 is possible without releasing the
latch 31 and raising the head [1, and conse
quently, it is possible to rotate the cam 44 through
engage a pin 43 extending from the bar 38 sub
stantially at the same time that pin 35 engages
the lower portion of lever 3|, upon movement of
Upon movement of the wheel 5 in a clockwise
direction as seen in Figure 1, it is desirable that
the respective clamps T be actuated into their
the bell crank lever 33. It is thus apparent that
when the bell crank lever 33 is moved in a clock
wise direction as seen in Figure 6, and in the
open position in reaching the station 8, as here
inbefore pointed out, and accordingly, it is‘ de '30
sirable to provide suitable means for engaging
vicinity of the dotted line position there shown,
the lug 42 will be effective to move the pin 43 and
bar 38 toward the right thereby releasing the
latch at 31, and consequently permitting the up
ward movement of the head I‘! in consequence
of a further movement of the bell crank lever 33.
As pointed out above, the bell crank lever 33, is
‘rigidly mounted on the shaft 32 which extends
through the casting being journaled for rotation
therein. A cam member 44 is rigidly mounted on
the pin 32 on the oppositeside of the casting from
the bell crank lever 33, so that it is apparent that
the cam 44 will be rotated with the bell crank
lever 33 about the pin 32 as an axis. A suitable
spring 45 may be provided in engagement with
the cam member 44, and having its opposite end
anchored to the casting at 46, is effective to bias
the cam member and the bell crank lever 33 into
the position shown in the full lines of Figures 5
vand 6.
A pedestal 41 is mounted upon the head I‘! and
is preferably adjustable relative thereto by any
suitable arrangement such as, for instance, a nut
48. At the top of the pedestal 41, a lever 49 is
pivotally mounted and the opposite end of the
lever 49 is disposed for engagement with the cam
member 44 when the head I‘! and its adjunct
parts are at or near their lowermost position, as
60 illustrated in Figure 5.
It is apparent, however,
that when the head I‘! and its adjunct parts are
raised to the dotted line position illustrated in
Figure 6, the lever 49 will be carried upwardly
therewith, so that the outer end thereof is lifted
65 out of engagement with the cam 44. Inter
mediate the ends of the lever 49, a stem 5| is
pivotally mounted for operating the intake valve
24, and it may be pointed out that when the parts
are in the position shown in Figure 5, that is, with
the head I‘! in its lowermost position and the bell
crank lever 33 at rest under the action of spring
45, the intake valve 24 is in this embodiment then
in its open position. An operating stem 52 for
the exhaust valve 25 is disposed for engagement
with the lower surface of the lever 49, and it may
an angle of almost 45° and thereby manipulate
the valves 24 and 25 to regulate the pressure on
the diaphragm I9 without releasing the latch 31..
the lug 34 for the bell crank lever 33 on each of
the clamps as they near the position 8, it being
recalled that when the bell crank lever 33 is
moved sufficiently in a clockwise direction, the
latch 3“! will be actuated to release the head I’!
and permit the pin 35 to raise the same through
lever 3|. A devicevfor engaging the lug 34 of
the bell crank lever 33 as it approaches the work
receiving position 8, may consist in any suitable
obstruction in the path of the lug 34, but for the
purpose of illustration, a suitable mechanism,
shown more particularly in Figures 7 and 8, has
been provided for accomplishing this and other
z‘
functions in cooperation with the bell crank lever I
33. A suitable bracket 54 is mounted upon one
of the upper horizontal members 2 and extends
inwardly therefrom in the direction of the wheel
5. The bracket 54 is provided with a pair of
bosses 55 extending upwardly therefrom and in
spaced relation to each other. Pivotally sup
ported between the respective bosses 55, is an
arm 56 which extends therefrom in a direction
toward the wheel 5 and has its outer end 5‘! dis
posed in the path of the lugs 34 on the bell crank '_
levers 33 of the respective clamps 'l. The arm
55 is mounted for rocking upon a shaft 58 car
ried by the bosses 55 and the shaft 58 is sur~
rounded by a suitable coil spring such as 59,
anchored at one end of the bracket 54, and hav 60
ing its other end secured at 611 to the arm 56.
It is thus apparent that the spring 59 is effective
to bias the arm 56 in a counterclockwise direc~
tion, as seen in Figure '7, and the movement of
the arm 55 in this direction is limited by a suit
able stop pin 6| which may be adjustable to the
position desired.
Since as it is pointed out above, the bell crank
lever 33 of the respective clamps is continuously
biased in a counterclockwise direction, as seen "
in Figure 6, the tendency will be for the bell
crank lever 33 to assume its normal position upon
release of the lug 34 from the end 5‘! of the arm
56.
Similarly, upon rocking of the arm 56, so
that the end thereof is carried upwardly ap- '
4
2,149,594
proaching the dotted line position illustrated in
Figure '7, the bell crank lever 33 will follow there
behind under the action of spring 45, so that when
the end 41 of lever 56 is engaged with the knob
34 of a particular clamp, slight movements of the
arm 56 will cause a corresponding movement in
the clamp engaged. Accordingly, when the arm
56 is rocked about its pivot 58, its movement in
the zone adjacent the position shown in full
10 lines, will be effective to cause a corresponding
movement of the head I] vertically. Likewise,
when the arm 56 is rocked about its pivot in
positions approaching the dotted line position.
of Figure '7, the bell crank lever 33 in engage-r
15 ment therewith will have been sufliciently re»
leased to have permitted the head I‘! to drop
into its lowermost position so that rocking of
the arm 56 is effective to regulate the relative
position of valves 24 and 25, it being understood
20 that when the arm 56 is rocked into an extreme
position in the clockwise direction, as seen in
Figure '7, the end 5'! thereof will be moved a suf
?cient distance laterally to entirely release the
knob 34 of the particular clamp which had been
25 in engagement therewith, so that the normal
position of the clamp parts will be assumed in
which the head I‘! is lowered and latched, the:
intake valve 24 is opened and the exhaust valve
25 is closed.
30
Anysuitable device such as, for instance, a
treadle 62 may be provided for rocking the arm
56 to consequently control the position of the vari
ous parts of the clamp which is in engagement
therewith. The treadle 62 may be pivotally
35 mounted such as at 63, and is preferably pro
vided intermediate its end with a vertically ex~
tending link 64. At the upper end of the link
64, a suitable tang 65 is provided for releasably
engaging the arm 56. A suitable guideway such
40 as, for instance 66, is preferably provided in the
bracket 54 for guiding the movement of the tang
65. In the illustrative embodiment shown in the
drawings, the guideway 66 comprises a slot which
is adapted to slidably receive the tang 65. One
45 face of the slot 66 is recessed to receive a slidable
tongue 61 carried by the arm 56 and a spring
68 is preferably provided for maintaining the
tongue 61 in its extended position. A spring 69
is preferably provided for maintaining the treadle
62 in its upper position and in this illustrative
embodiment, the spring 69 is anchored at one
end to the bracket 54, and at its opposite end to a
suitable clamp such as ‘H, for engaging the link
64 intermediate its ends. From the construction
55 just described, it is apparent that when the
treadle 62 is moved downwardly from its normal
position, the tang 65, being in engagement with
the tongue 61, will also move downwardly carry
ing with it the tongue 61, so that the arm 56 is
60 rocked in a clockwise direction about its shaft
58. It is apparent that both the springs 59 and
69 are effective to bias the treadle, link and tang
toward their uppermost position so that ‘any
rocking of the arm 56 must be in opposition to
65 the forces of the springs 59 and 69. When the
treadle is su?iciently depressed to move the tang
65 downwardly to its dotted line position, illus
trated in Figure 7, it is apparent that the tongue
61 will be released thereby and under the action
70 of spring 56, the arm 56 will be drawn back into
the position illustrated in full lines in Figure 7.
Upon release of the treadle, however, the spring
66 will operate to draw the link 64 and the tang
65 upwardly to a position in which the inclined
75 faces of the tang 65 and the tongue 61 cooperate
to compress the spring 68 and permit the tang
~65 to move into its uppermost position past the
tongue 61.
As pointed out hereinbefore, the ratchet wheel
16 is rigidly mounted upon the shaft 4 for rota
tion with the wheel 5, and intermediate the
ratchet wheel 6 and the wheel 5 is rockably
mounted upon the shaft 4 an arm 12 having at
its outer end a pawl 13 for cooperative engage
:ment with the teeth of the ratchet wheel 6. It 10
may here be pointed out that the ratchet wheel
6 is preferably provided with a number of teeth
corresponding to the number of clamps which are
disposed about the periphery of the wheel 5, so
that when the pawl 73 operates to advance the 15
ratchet wheel 6 one notch, then likewise will the
wheel 5 be rotated a distance equal to the spacing
of the successive clamp ‘i. The outer end of the
arm ‘i2 is connected‘by a suitable rod ‘M with
an eccentric 15. The eccentric ‘I5 is mounted 20
upon a shaft 1'6, suitably journaled in a housing
‘H, within which is provided any well-known type
of worm gear driving mechanism therefor. As~
sociated'with the eccentric '15 is a cam 18, the
periphery of which is, with the exception of the 25
notch-like portion 16, concentric with the shaft
“36. A bell crank lever BI is pivotally mounted
at 82 and carries at one end a follower 63, dis
posed for engagement with the cam ‘E8. The bell
crank lever 8! is rigidly secured to the shaft 82 30
by any suitable means such as, for instance, a
spline connection, and likewise a suitable clutch
operating device such as 84 is secured to the shaft
82 for movement with the bell crank lever. In
the preferred embodiment of this invention, a
spring 85 is provided for biasing the parts just
described in a counterclockwise direction so that
when the cam 18 has rotated to a position in
which the notch '16 comes adjacent the follower
83, the spring 85 will be effective to force the
follower 66 into the notch, thereby permitting
suf?cient movement of the bell crank lever and
the clutch operating arm 86 to permit release of
the clutch. Any suitable driving device such as,
for instance, a motor 86, is, of course, provided.
The other arm 8'! of the bell crank lever 8! ‘m
connected by a suitable ?exible connection such
as, for instance, a chain 88, with the treadle 62.
It may here be pointed out that the length of the
chain 88 is preferably su?icient to permit a sub 50
stantial movement of‘ the-treadle 62 before the
chain is suf?ciently tightened to actuate the bell
crank lever 8|. By this arrangement, the treadle
62 is not effective to actuate the bell crank lever
8! until moved downwardly to an extreme posi
tion. When the treadle 62 is moved downwardly
to an extreme position, it will be recalled that
the tang 65 is drawn downwardly, carrying with
it the tongue 61, so that the arm 56 is rocked suf
?ciently to release the knob 34- of the bell crank
lever 33 with which it had previously been in
engagement and at the same time, during the
latter part of the downward movement of the
treadle 62, the bell crank lever 8| will be rocked
in a clockwise direction about its pivot 62, so that
the clutch device 64 is thrown into engagement
to effect a connection between the motor 66 and
the worm gear driving mechanism for the shaft
76. When the clutch device 84 is moved into its
engaged position, it is apparent that the follower
83 on the bell crank lever BI is moved out of the
notch 19, and it is further apparent that upon
engagement ofv the clutch, the shaft ‘i6 will be
rotated to move the cam '58 relative to the fol
lower 83, so that the treadle 62 may then be re
75

gaged position until a complete revolution of
shaft 19 has brought the notch 19 adjacent the
follower 83 where the spring 85 will be effective
to force the bell crank lever 8| in a counterclock
wise direction, so that the follower 83 is nested
again in the notch '59 and the clutch is disen
gaged. It is thus apparent that once the machine
is set intooperation, the operation continues for
only one revolution of shaft 16, which, in fact, re

A suitable locking pawl 89 is preferably pro

Vided for engaging the teeth of the ratchet wheel
6 to prevent it from movingrbackwardly during
the downward movement of the pawl 13.
Since the diaphragm I9 is, adapted to be. ex.
' panded under pressure of compressed air w1th1n
the air chamber de?ned by the recess 18 in head
l1, it is necessary that a source of compressed
air or other suitable ?uid be obtainable. Accord
, ingly, a compressor 9 I, which may be of any suit
able andwell-known type, is provided.
An air
reservoir 92 is in accordance with the usual prac
tice provided for association with the compressor
9|, and any suitable type of pressure gage 93 is
preferably
associated therewith. In accordance
39,.
' With the preferred embodiment of this invention,
the pressure gage 93 may advantageously be of
an automatically regulating type adapted to
maintain maintain a constant pressure within the
._ reservoir 92. A suitable, conduit 94' is provided
*for conducting the compressed air away from the
reservoir 92. Any suitable type of connection
such as, for instance, 95, is provided for connect
ing the conduit 94 with the shaft 4, and for main
40
5
taining an air-tight connection between these re
spective elements during rotation of the latter.
The shaft 4 is preferably bored to provide a con
duit therethrough for the compressed air from
the reservoir 92, and a suitable outlet from the
96 is essentially provided at or near the hub
415 bore
95. A suitable conduit is provided for connect
ing the outlet referred to with a supply conduit
91 which is preferably disposed near the outer
periphery of the wheel 5 and in a convenient lo
cation for permitting the connection of the sup
ply pipes 98 for therespective clamps; it being
understood that each of the respective supply
pipes 98 is connected with the nipple 23 of the
corresponding clamp.
An auxiliary clamp control arm 99 is preferably
55 provided
to insure the opening’ of the intake valve
24'after the bell crank lever 33 has been released
from the endv 51 of arm 56. The arm 99 may ad
vantageously be mounted upon bracket 54 and
60 extends upwardly and outwardly therefrom so
that the upper end thereof, which may be pro
vided with a suitable abutment I99, is disposed
for engagement withv knob 34 on bell crank lever
33, if, as under some conditions, the bell crank
65 lever has not been moved-into the position illus
trated by full lines in Figure 6 by the action of
spring 45. It is thus apparent that the only time
when the arm 99 comes into operation is under
such a circumstance that for some reason the
70 particular bell crarnk lever 33 has not movedinto
its normal position under the action of its spring
45.
,
From the foregoing description, it is apparent
that whena particular clamp 1 has reached the
work-‘receiving position at 8, and the wheel 5 is
stationed in position for conveniently placing‘
the upper parts, which have been previously
cemented together and are now to be retained in 10
their'proper alined positions during the setting
of the cement, in position within the clamp 1;
it being understood that the operator is pref
erably so stationed that the treadle 62 may be
readily operated by his foot. Thus, when the
wheel 5 is rotated to bring a particular clamp
into work-receiving position and the clamp is
raised to release the work just prior to the time’
when the wheel 5 is arrested, the operator may
then remove the work from .the clamp in its work
20,
receivingposition; it being understood that the
particular piece of work which is removed has
been held in position within the particular clamp
during an entire revolution of the wheel 5', so]
that the cement or glue has had su?lcient time 25.
to, set and the upper partsmay now be removed
without danger of them becoming relatively dis
placed.
The clamp is now in position for the reception
of an entirely new piece of work which consists 30
usually in a plurality of separate pieces which go
to form apcompleted upper, such as, for instance,
the quarters and vamp; it being understood that
they have. previously received an application of
cement or glue with which it is desired to secure 35
themrtogether. The operator places the respec
tive upper parts upon the support I2 and. ad
justs them until they are brought into the desired
relation at which time the treadle 62 may be
operated to raise the end 51 of, arm 55, as here 40
inbefore described, thereby permitting a clock
wise movement of the bell crank lever 33, and
consequently, permitting the head. I‘! to be low
ered an, amount corresponding to the movement .
of the treadle 62, all of which has beenlmore- ,
speci?cally described hereinbefore. In this re
gard, it may be particularly pointed out that
when the, head "is in its lowermost position, it
isrpreferably spaced slightly‘. away from the sup
port [2, so that therewill be permitted a slight 50,
movement of the upper partsrelative to the clamp
even after the, head IT has reached its lowermost
position. By reference to. Figs. 6. and 2, it will be
observed that the movement of'the treadle 62
and the corresponding movement of the bell 55
crank lever 33 is effective during movement in
the zone designated as ato raise and lower the
head l1, and that movement of the treadle 62 and
bell crank lever 33 throughout vthe‘zone desig
nated as b is effective to .manipulate the valves
24 and 25. When the operator has placed the
upper parts upon the support l2, the bell crank
lever is moved in accordance with a corresponding
movement of the. treadle 62 to, drop the head l1.
It will be recalled, however, that the head l1 65
when in its lowermost position is suf?ciently
spaced'from the support l2 topermit. a_ slight
movement of the upper parts relative to the
clamp, so that even after the head has been:
dropped, the operator may further-adjust the 70.
upperparts before the air pressure is admitted
to the chamber I 8, so that the diaphragm l9
isexpanded against the upper parts to» positively
hold them in position.
When theoperator,issatis?ed that the‘ upper
6
2449.594
parts are in the desired position the treadle 62
is moved downwardly into the zone designated
in Fig. 2 as 1) thereby effecting a corresponding
movement of the bell crank lever 33 in the zone I)
and actuating the intake valve 24 into its open
position to admit the compressed air from res
ervoir 92 into air chamber l8. The treadle 62
may be oscillated thru the zone designated as b
to effect a corresponding movement ofthe bell
crank lever thru zone I) and thereby manipulate
the intake and exhaust valves 24 and 25, respec
tively, to expand and collapse the diaphragm l9
thereby varying the pressure on the upper parts
I?l until the ?nally desired alinement of the
15 upper parts relative to each other and a support
I2 is obtained. When the desired alinement is
obtained the treadle 62 may be moved further
downwardly into the zone 0 causing a correspond
tongue 61' will be released by tang 65 before the
with the diaphragm l9 expanded against the
upper parts l0! supported by the supporting
table l2 as illustrated also in Fig. 3. At the time
. the treadle 62 is moved downwardly into the zone
30 designated as c and after the arm 56 has been
rocked su?iciently to release the knob 54 on the
bell crank lever 33, the chain 88 will, as herein
before described, become tightened so that fur
ther downward movement of the treadle 62 will
35 effect rocking movement of the bell crank lever
8| with its shaft 82. As hereinbefore pointed
out when the bell crank lever BI is rocked in a
clockwise direction as seen in Fig. 9, by applica
tion of force of the treadle 62 thru chain 88, the
40 follower 83 is raised from the depression 19 and
60
moved into position adjacent the end 51 of arm
56, the parts are preferably so related that the
treadle 62 has been effective to engage the clutch
so that in spite of the fact that the operator
did not take his foot off the treadle 62 immedi
ately upon initiation of the clutch, the arm 56,
will have been released and under the force of:
spring 58 will have assumed a position in which
clamp to release the knob 34 on the bell crank
55
treadle 62 by the time the advancing clamp has
thereof, substantially into the dotted line position
illustrated in Fig. 7, where it will be recalled the
end 51 is sufficiently displaced laterally from the
I lever 33 and upon such release the clamp parts
25 will assume the position illustrated in Fig. 11
50
arm 33 of the next succeeding clamp. Even in
the event that the operator has not released the
‘ ing movement of the arm 56 raising the end 51
20 "
45
When the clutch connection has been inadé
and the pitman rod 14 started upon its upward
movement to effect an angular movement of the
wheel 5, the clamp! ‘l which has been adjacent
the work receiving station is moved away from
the work receiving station and the next succes
sive clamp is advanced into that position. When
the next successive clamp is advanced into the
work receiving position, the treadle 62 has then
been released by the operator so that the arm 56
has assumed its horizontal position illustrated in
full lines in Fig. 7 so that the end 51 thereof is
disposed for contact with the lug 34 on the crank
the clutch 84 is moved into its engaging position
to effect a connection between the driving motor
86 and the driven shaft 16. Upon the comple
tion of such a positive connection between the
driving ‘motor 86 and the shaft 16 the latter will
be rotated sui?ciently to move the depression 19
thru an angle suf?cient to bring it out of aline
ment with the follower 83 and the treadle 62
may then be released without interfering with
the operation of the clutch. Upon rotation of
the shaft 16 it is apparent that the eccentric 15
will be operated to oscillate the'pitman rod 14
in a substantially vertical direction. Upon such
oscillation in the longitudinal direction of the
pitman rod 14, the arm 12 will be rocked on
shaft 4 which rocking, it is apparent, will be
effective during the upward movement of the rod
14 (when the pawl 13 is in engagement with the
ratchet wheel 6) to effect a rotation of the wheel
5 in a clockwise direction as seen in Fig. 1. It
may be here pointed out that the throw of the
eccentric ‘I5 is preferably such as to cause an
angular movement of the arm 12 corresponding
to the distance between successive teeth of the
65 ratchet wheel 6 upon each revolution of the
eccentric 15. Thus when the pitman rod 14 is
moved in an upward direction the ‘mechanism is
effective to advance the wheel 5 a distance cor
responding to the angular displacement of the
70 teeth on the ratchet wheel 6 and also correspond
ing to the displacement of the successive clamps
‘I while upon downward movement of the pitman
rod 14 the arm 12 is rocked in a counterclockwise
direction around shaft 4 in order to bring the
76 pawl .1 back into the next operative position.
the end 51 thereof, will be disposed in the path
of the lug 34 of the advancing clamp.
From an inspection of the various ?gures, it is,
apparent that the lug 34 on bell crank lever 33
of an advancing clamp comes into engagement
with the end 51 of the arm 56 before the clamp has
reached its work receiving position and before
the eccentric 15 has made one-half revolution and,
it is thus apparent that when the end 51 of arm,
56 engages the bell crank lever 33 of an advanc
ing crank further movement of the wheel 5 sub
sequent to such engagement will be elfective to
rotate the bell crank 33 in a clockwise direction
as seen in Fig. 6 for instance, thereby ?rst clos
ing intake valve 24 and next releasing exhaust 40
valve 25 during the movement of the bell crank
lever 33 thru zone b; and when the wheel 5 has
advanced sufficiently the bell crank lever 33 will
be moved into zone a whereupon the further
movement will release the latch 35 and move the 45
head I] into its raised position illustrated in dot
ted lines in Fig. 6. The parts will preferably be
arranged so that when the bell crank lever 33
has been suiiiciently rotated to raise the head I1
into uppermost position, then the shaft 16 with
cam 18 will have made one-half revolution so that
the depression 19 will be diametrically opposite
its original position and further movement of the
shaft 76 will be effective to retract the pawl 13
until it falls into engagement with the next suc 55.
cessive ratchet tooth. When the pawl falls into
engagement with the next successive ratchet
tooth the parts are so positioned that the notch
19 will come into position adjacent the follower
83 whereby the spring 85 will be effective to rock
the bell crank lever 8i and its shaft 82 in a coun
ter-clockwise direction as seen in Fig. 9 and force
the follower 83 into the depression 19 thereby per
mitting release of the clutch.
Upon completion of this cycle of events, it is'
apparent that another clamp has‘ been moved
into work-receiving position and that the clamp
has been released so that the operator may read-l
ily remove the upper parts IDI therefrom, they
having been retained in position for su?icient
time to permit setting of.’ the cement so that they
may now be removed. The operator removes the
upper parts upon which the cement has set and
replaces them with other parts which are to‘ be
2,149,594
clamped during the setting of the cement there
on, as hereinbefore described.
