Fig. 13 is a cross-sectional view illustrating a
15 spiral or an annular thread and groove arrange
centrally of the cylinder head and open to the
atmosphere. The valve stem also projects slidably
directed peripheral ?anges l3 and I4 at opposite
ends, seated in annular recesses i5 and i5 in'the
heads respectively. Such heads and the wall I2
are secured together by bolts il passing through
25 marginal portions of the heads, and longitudinally

reciprocatory movement, and slidably projects
through an opening 49 into a space 50 located
-
heads i0 and II are provided which support be

the upper half of the cylinder head, and passage
ways 45 and 41 in the lower half. In each pas
sageway a valve stem 48 is mounted for vertical
member.
20 tween them a cylinder wall l2 having outwardly
35
space interiorly of the handle 2| by means of a
recess 4|, so that ?uid under-pressure will enter
the handle, and the opposite end of the casting is
open at its point of connection with the cylin
der head I 0. The valve arrangement for con
trolling the ?ow of the ?uid is located on the
outerside of the cylinder head I 0 as shown by
, Figs. 1 and 4, and as shown best by Fig. 4, such
arrangement includes passageways 44, 45, 46 and
ment that may be used on the jaws and male rivet
Referring to Figs. 1 and 2, spaced cylinder
30
space in the casting l3 communicates with the
over the outer surface of the cylinder wall. With
in the cylinder, a piston I5 is provided which has
its central portion apertured to receive a piston
rod i8, and this rod has a shoulder 20 at one
side of the piston for holding the latter in place,
and at the opposite side of the piston, a lock nut
2| threaded thereon to hold the piston against
the shoulder. For holding the lock nut in posi
tion against loosening, a wire or the like 22 may
extend partially around the periphery of the nut
in a groove therein, and then project radially
through an opening in the nut and partially into
an opening (not shown) in the rod. At the left
side of the piston, as seen in Fig. 1, a. pin 23 is
provided which is threaded into the end of the rod
as shown at 24, and this pin is reciprocatory in
a bearing sleeve 25 disposed in an opening cen
trally formed in the cylinder head ill. The op
posite end of the piston rod slidably projects
through an opening in the cylinder head ii and
this opening extends entirely through the head,
in contrast to the opening in the head I. having
the sleeve 25. A stu?ing box 35 is threaded into
the head ll around the rod I! to prevent the
50 escape of ?uid under pressure in the cylinder
along the piston rod to the outer side of the
head. The slidable mounting of the piston rod
in- the heads iii and il assists in locating and
guiding the movement of the piston, and both
55 supports are desirable particularly when the pis
ton is provided with cup washers 25 and 21 bolted
to the outer margin of the piston as indicated at
2l'.aswearonsuchwashersisreducedtoa
minimum.
The head I! also serves as a support for ahan
dle 3! which is secured thereto at its upper end
by means of .bolts 52 as shown by Fig. 2, and at
its opposite end to one end of a casting 52 by‘
means of bolts 54. This casting at its opposite
' end is secured by bolts 25 to the lower side of the
cylinder head ll. It will be noted that the handle
member 3| is provided with hand and ?nger abut
ments I1 and I5 and in general is shaped to facili
tate manual gripping of the machine.
For supplying ?uid under pressure to the cyl
70
60
inder, to- reciprocate the piston therein, the han
dle 3| and the casting 53 are of hollow construc
tion and- a ?uid pressure supply line 45 is con
nected to the casting 33 to supply ?uid under
75'. pressure to both the handle and casting. _The
through a valve seat 5i secured in the passage
way, and on theother side of the valve seat, the 20
stem slidably passes through a valve disc 52 hav
ing a sharp marginal edge 53 on its face adjacent
the seat adapted to engage a sealing ring 54 lo
cated in a groove in the seat. For lifting the valve
disc 52, it being slidably mounted onthe valve 26
stem, the latter is provided with a shoulder 54',
and on the other side of the disc the stem is pro
vided with a second valve disc 55 rigidly mounted
thereon as by threading. The latter disc simi
larly to the disc 52, has a marginal sharp edge 30
56 on its face for engaging a sealing ring 51
located in a groove in the upper face of the disc
52.
The disc 52 has one or more openings 51’
along the valve stem so that ?uid under pressure
in the space in the passageway at the disc side 35
of the seat may meter through the disc along the
stem when the disc 55 is raised thereabove. When
the disc 52 is raised, the ?uid may also ?ow
through larger openings 59 in the seat 5| into the
passageway below the seat. Normally the stem 40
is urged into the valve closing position by means
of a helical spring 50 encircling the stem and
engaging at one end the valve seat 5| and at its
other end a collar 5| rigidly mounted on the stem.
When the stem 45 is in a valve closed position, 45
it is apparent that the stem will be held down
wardly' by means’ of the spring 65, and thatthe
discs 52 and 55 will entirely close the valve. When
the stem is moved into the valve lifting position,
the disc 55 will initially be raised, and this will 50
permit a small ?ow of ?uid under pressure
through the disc 52, and- openings 51", then
through seat 5!, and this is desirable because’ the
pressure of the ?uid on both sides of the valve
may then be somewhat neutralized, and this re 55
sult may be obtained more easily by lifting the
small valve disc 55 instead of the larger valve
disc 52'. After the pressure is somewhat neutral
ized, it is not di?lcult to raise the disc 52 to allow
the ?uid to ?ow more rapidly through the valve 60
seat. For the purpose of illustrating the func
tion of the four valves involved, the valve in
passageway 44 is indicated at 65, that in pas
sageway 45 at 56, that in passageway 45 at 61 65
and that in passageway 41 at 55.
Still referring to Fig. 4, the casting 33 has an
offset passageway ‘I0 communicating directly with
the passageway 45 in_ the valve arrangement at
the valve disc side of the valve seat, and since
the casting is in direct communication with the
?uid pressure supply line 40,, the passageway 45
will always have ?uid under pressure therein at
this side of the valve. 4 As shown best by Figs. 1
and 2, the passageway within the handle 2! com 75

is that the smaller valve disc 55 on valves 01 and
arrangement, above the seat therein. There
fore, it will be apparent that the vertically aligned 68. will ‘initially open to allow neutralization of
passageways l5 and 46 above and below the valve pressure on both sides of thev valve, and this in

and that when one set of valves is fully open, the
tending aperture 14, and the latter in turn com

valve 65, and ?uid under pressure to the right
upper extremity communicates with a passage
way 16 formed in a casting 11‘ secured by bolts end of the cylinder is shut oil’, since the closing
18 and 19 at opposite ends to the cylinder heads of valve 66 cuts oil communication between the
20 Ill and II respectively.v This casting has a lon~' passageway in the handle 3| to the passageway,
15. As valve 61 opens, ?uid under pressure ?ows
gitudlnally extending rib type passageway 80 ex
through the casting 33 through the passageway
tending to the cylinder head H, and such pas
sageway then communicates with a passageway
8| extending downwardly-through the head ll
25 and then laterally through thehead as indicated
at 82 in Fig. 1, where it communicates with the
interior of the cylinder at'the right side of the
piston. Accordingly, when valve 68 is open, ?uid
under pressure will ?ow into the right end of the
30 cylinder. As seen in Figs. 1 and 4, the passage
way 46 communicates with an opening, 83 ex
tending directly through the cylinder head 10 and
communicating with the interior of the cylinder
.at the left side of the piston, such opening 83
35 being at the spring side of the valve seat‘in thev
passageway. Accordingly, when valve 61 is open
?uid under pressure will ?ow to the left side of
the cylinder. As shown by Fig. 4, the passage
way’“ above the valve seat communicates with
40 an opening 85 extending laterally through the
cylinder head in and communicating directly
with the interior of the cylinder, whereas below
the valve seat, the passageway communicates
with'a laterally extending opening 86 in turn
45 communicating with an exhaust passageway 81
extending downwardly through the cylinder head
and finally opening to the atmosphere through
an opening in the casting 33. The passageway
41 at the spring side of the valve seat communi

46, through the valve therein, through the pas
sageway 83 and into the left side of the cylinder,
while the opening of valve ;68 permits the right 25
end of the cylinder to exhaust through the pas
sageways 92, 9|, 90, 89, the valve 68, and into
the exhaust passageway 81. The piston then
will move to the right.
Upon release 01' the _
trigger-93, the valves 61 and 68 will close,land 30
valves“ and 86 will open. It then will be ap-_'
parent‘ that fluid under pressure will communi
cate with the right end of the cylinder, and fluid‘ ’
will be allowed to exhaust from the left end of
the cylinder into ‘the exhaust passageiivayv l1, 35.
thus moving the piston ‘to the left.
.
It will be noted in Fig. 1 that one of the bolts
21' at the margin of the-piston has an extension,
indicated at 94', which is substantially aligned
with the exhaust opening 82 in head II, This 40
pinis adapted tomove into the opening ,92 when
,
the piston approaches head II, and serves as‘a
metering element to reduce the e?ectivejsiae of
the exhaust passageway gradually and hence to
-
prevent rapid exhaust ofn?uid at the right side 45
of the cylinder when the piston is moving near
to and toward such head. , In‘ this wayv a ?uid
cushion is provided to cushion the piston. and the
primary purpose thereof will be presently de
scribed.

the passageway communicates with an'opening 89
in turn communicating with a v

55 extending upwardly and to a longitudinally-ex
‘ tending passageway 9| extending parallel to the
passageway ill in the casting 11. Such passage
paratus described, that end of the piston rod is
projecting beyond the cylinder head _i I, has as
best shown by Fig. 3, a slot indicated at-IOII and
at opposite ends of this slot, bearing elements 55
I0! and ")2. Each of such elements preferably
has ribs I03 at opposite
v of the slot to retain
the elements in position. It will be appreciated
that either element may be inserted by placing
60 g‘lassalgeway 92’ through the head H, as seen in - it longitudinally in the slot. with the ribs I03 00

to the upper side of the cylinder head II. It is
to be, noted that the length of the arm portion
above the pivot III! is much less than the length of
the arm portion below the pivot, and consequent
ly a greater force may be exerted by the upper
end of the arm, with a smaller force acting on
the lower end of the arm, because of the mechani
cal leverage obtained. Around the arm and the
end of the piston rod projecting from the cylinder
10 head II, a. housing II II’ may be provided, which
is secured to the cylinder head by means of bolts
III as shown by Fig. 2. This housing at its upper
side has an opening for the arm I“ and the inner
portion of the barrel III and similarly has an
other opening in its lower wall for enabling ad
I justment of the stuffing box 30 and the avoidance
of dirt collecting within the housing.
Nowsreferring to Fig. 6, it will be observed that
the upper end of the arm I04 has a rounded por
20 tion II3 which is disposed in an aperture H4
formed in a reciprocaiory member I I5 in the bar
rel I09. At either end of the opening I ii, a bear
ing element I I6 isprovided which is secured in
place by means of screws II'I threaded into the
member IIS, and these elements form bearing
seats for the rounded portion I I3 of the arm I".
It will be observed that the bottom side of the ap~
erture II‘ has diverging side walls as indicated
at ill to permit rocking movement of the arm
with respect to the member I IS without interfer
ence. \Adjacent the aperture Ill, the outer sur
face of the member II! is threaded to receive a
sleeve Ill, and this sleeve is adjustably locked in
position by means of a lock nut I II. The outer
35
end of the sleeve III, as best shown by Fig. 8. has
an opening de?ned by three circurnferentlally
spaced cylindrical surface sockets I22, I23 and I24
whose axes converge toward the outer end of the
sleeve.
40
Fig. 10 also shows the sockets I22, I23 and I“
but on a section farther from the right end of the
sleeve. It will be observed from Figs. 8 and 10,
that each of such sockets beginning from the
right end of the sleeve is less than semi-cylindri
cal. and that the arc of the surface becomes larger
gradually until at the section shown by Fig. 10
the socket is substantially greater than semi
cylindrical.

this connection that preferably the gripping sur
face of each jaw is provided with grooves or
threads as indicated at I26, and such threads or
grooves may be like that shown in Fig. 13, in which
one sideis radial, the base substantially axial, and
the other side axially tapered inwardly toward
the axis, in a direction away from the outer end
of the jaws. For holding‘ the jaws toward the
outer end of the sleeve, a three legged stool-like
element indicated at I21 is provided, which is 10
reciprocatory in the sleeve, and which has legs
I21’ projecting into the respective sockets in the
end of the sleeve, and into contact with the re
spective jaws. The stool-like element is urged
against the jaws, by a spring I28 engaging the end 15
of the element, and encircling a reduced cylindri
cal portion I29 on the end of the member I I5, and
abutting a shoulder thereon.
The outer end of the barrel I09 is provided with
an anvil plate I3I which is held in position by 20
swaging or spinning over a marginal ?ange on the
end of the barrel indicated at I32. The rivet to
be set generally may comprise a tubular female
member indicated at I35 in Fig. 10 having a head
I 36 for engaging the outer side of a structure I31 25
being riveted. The inner end of the female mem
ber is engaged by a head I38 ch a male shank I39
projecting through the female member and be
yond the head I36 to provide a gripping portion
I 40. This latter portion preferably has grooves 30
or threads I40’ for coa'ction with the grooves or
threads I26 on the jaws, which have radial sides
engaging the radial sides of the latter threads.
The tapered parts of the threads on the jaws of
course facilitate entry of the male rivet member
between them. In order to facilitate initial entry
of the male member between the jaws, the end
of such member may be beveled or the jaws may
be countersunk. The anvil plate I3! has an open
ing “I for receiving the projecting end of the 40
male member, and such projecting end is adapted
to be positioned between the jaws and to be
gripped thereby when the rivet is set. The anvil
also has a conical recess I42 for engaging the head
I36 on the female rivet member. In setting the
rivet, it may be inserted as shown by Fig. 6, and
then the machine and rivet-may be moved into
such positions that the rivet projects through the
openings in the structure I 31 as shown by Fig. 10.
Then by so operating the machine, that the mem
ber I I! is moved to the left in the barrel I", the
jaws will grip the male member and pull it, and
the reactionary force to the pull naturally will be
imparted through the anvil III against the head
Each of such sockets receives a jaw I25 having
its outer surface cylindrical to fit the socket in
which it is disposed, and the inner surface of this
jaw as best shown by Fig. 6, while curved, has its
axes of curvature substantially parallel to the axis
of the sleeve. In other words, each jaw has an I" on the rivet. It follows that the male member 55

be moved throughthe female member, and

sockets, their outer surfaces will remain in con
course facilitated by the beveled end of the rivet 70
