armature 2I-8 carries at one end an adjusting

the rod 208 by means. of a spring 224 secured to
an extension 225 of ‘the armature, the other end

80 The adjustment just described is provided so
that when the electromagnet H8 is energized by
establishing a circuit, as shown in Fig. 16, from
positive battery over wires SIB and 329, through
winding of magnet 2l8, through contact 285

presently more clearly appear.
Having further reference to Fig. 17 it is seen
45' that bracket 205 is provided with a vertical por
tion 221 on which is adjustably supported a sec
toral or‘ fan-shaped indicator dial 228, more
clearly shown in Figs. 20, 21 and 22. The dial
228 is pivotally held by a collar nut 229 about
50 which it is slightly rotatable, the amount of
movement of which is limited by a slot and screw
adjustment 23$ (Fig. 19). As indicated in Figs.
18 and 21, the pointer 203 is provided at its outer
extremity with a reverted portion adapted to ?t
55 over and move along the arcuate edge of the dial
228. The annular pivotal portion of the pointer
203 (as clearly shown in Fig. 18) is provided on a
’ part of its peripheral edge with a series of pro

25 on a bracket 235 integral with the base I and is
provided with a short arm 236 to the extremity
of which is attached one end of a pointer return
spring 227, the other end oi’ which is secured to

a suitable number. Matrices of certain numbers

It is well known in the typographical art that
the amount of possible justi?cation in any assem
bled line of matrices is determined by the number 45
of spacebands contained in it. As previously men
tioned, a spaceband comprises a matrix-shaped
portion in which is slidably carried a wedge por
tion. _ The expansibility of the spaceband is den
termined by the di?erence between the thin end so
and the thick end of the wedge portion. Thus in
order that the spaceband may be e?ective to Justi

aforementioned di?erence in thickness, or ex

wedge portion is slidably moved along the matrix
shaped portion, which is held in alinement with so
the rest of the matrices in the line,‘ it will tend to
“?ll up", as it were, the space left between the
last matrix and the limiting gauge representing‘
the length of line. So, too, a similar result will
be obtained when two or more spacebands have 65
been included in the line; in which event the
spacebands will be effective to justify the line
when the diii‘erence between the totalized thick
nesses oi the matrices and the length of line is less
than the sum of the differences in thickness, or 70 '
expansibility of the spacebands.

times indicate with exactitude the relation be
tween the totalized thicknesses of the matrices
in a line and the aggregate amount of expansion
provided by the spacebands.
As shown in Fig.20, the dial 226 is provided
' adjacent its arcuate edge ‘with a scale or series
of graduations representing the number of ems
in a line of maximum length. As previously
noted, the reverted end. of the pointer 263 moves
1.}; along this edge of the dial from left to right, to
ward-zero, in response to the totalization of the
matrix thicknesses by the counting mechanism.
Thus, the distance from the pointer 263 to zero‘
indicates the amount of space left in the line to
29; be ?lled with-matrices, when the line contains no
spacebands. ' However, when spacebands are in
serted in the line, the space remaining to be ?lled
varies with the number of 'spacebands inserted.
So, to indicate-the justi?ability of the composed
23'j-line a pair of pointers 253 and 254 are provided,
the distance between the pointers 253 and 254 in
dicating the amount of expansibility of the space
bands. Since the distance from zero on the scale
to pointer 254 represents the sum of the thin
edges of all the spacebands (whether one or more)
in the line, and the distance from zero to pointer
253 represents the sum ‘of the thickest ends of
the spacebands, it is manifest that the distance
between the pointers 253 and 254 represents the
35,; di?'erence between these sums, which is the
amount of expansion, or expansibility, of -the
spacebands contained in the line.‘ . Therefore the '
space left in the line'to be ?lled, when spacebands
are inserted, isrepresented by the distance be
40' tween the pointer .203 and any point betwun
pointers 253 and 254.
To eil’ect the differential movement of pointers
253 and 254 toward the left (from the zero posi
tion)‘ the mechanism indicated in Fig. 19 is pro
ment to pointers 253 and 254, such that each time I;
the ratchet 262 is stepped one tooth, pointer 233
will be moved-a distance corresponding to the thin
end of the spaceband and pointer 254 will be
moved a distance corresponding to the thick end,
of the spaceband. Furthermore, the pitch of the 19;;
teeth of ratchet 262 is chosen to suit the size of
spaceband employed with the set size of the font
of type used, and hence members 253, 256 and
262, being integral, may be rendered interchange-g
A detent 266 pivoted at Hi to bracket 212, secured to portion 221, cooperates with ratchet 262
and pawl 265 to prevent the ratchet from slipping _
back when-the pawl 235 is moved into engage-' ~
ment with a succeeding tooth, thus maintaining 29;»
' the pointers 253 and 254 in their newly selected
position. Referring to Fig. 17, the end-of-line
or elevator keylever 213 is connected by a link
214 .to the auxiliary lever 215 pivotally carried
at 216 on bracket 205. Lever 215 is provided with 25;;
a laterally disposed arm 211 at the extremity of
which is pivotally carried the release rod 213,
the upper end of which is adapted to have shall
and socket connection with arm 216 of the detent
lever 266. When the keylever 213 is operated, the so;
effect of which, as will appear, is to restore the
entire apparatus to its original or beginning-oi
line position, downward movement is imparted to
rod 213 to rotate lever 263 (Fig. 19) in a counter-,
clockwise direction against the tension of spring”;
Detent 266 thus is disengaged from the _
ratchet 262 and in turn co-acts with the emusion 2320f pawl 265 to cause also the release or;

lever 215 which through link 288 (Fig. 21) im
parts clockwise rotation to the lever 209 fixed to
the operating shaft of the counter 281 to operate
the indicators therein in the usual manner. It
is thus clear that every time an elevator or end
of-line key is operated a record thereof is made
in the counter 281. As is customary, the counter
28'! is provided with a lever 292, the function of
which, when actuated, is to restore the indica

Signal mechanism
Since the amount of line to be filled with char
acters varies with the number of spacebands used
20.. in the line, and since the number of spacebands
in the line governs the amount of justification re
quired, it is apparent that as more spacebands
are used in a line less characters can be placed
in the same line so that it becomes necessary in
in Fig. 2.
Referring particularly to Fig. 22, there is shown
pivotally connected to arm 301 of the target 305 a
link 308, the other end of which is pivoted to the
outer extremity of arm 309 which, as is shown in
Fig. 2, is ?xed to the rocker member l5. When 10
the rocker member is actuated into either its
shift or unsliift position the target 305 will be
correspondingly actuated.
To move the rocker member l5. into the shift
or rearward position,‘the keylever 8 is operated 15 _
and is thus rotated about its pivot shaft 8 in a
counterclockwise direction (as viewed in Fig. 2)
to impart through link I8 and bracket 2| \oppo
site rotation to the rocker member 15 and likewise
to arm 303.
This movement of arm 309 causes 20 _
link 308 to move to the left, in Fig. 22, to impart

tact I13Mis provided with a resistance 332 and
a condenser 333 for spark protection. The con
tact I32, as previously described, is operated by
the bar I3I in the selector mechanism also shown
in Fig. 2. This bar I3I is actuated only upon
70 the operation of a function key at which time the
escapement mechanism, which initiates the op
erationof the'counting device, is disabled, due
to the breaking of the circuit which energizes the
escapement magnet I11. The contact 235 is op~
75 ' erated by the lever arm 234. shown in Fig, 1'1 upon
In Fig. 7,15 indicated a modi?ed- form of the to
stop bar arrangement in which stop bars 332,
analogous to stop bars 33, form a part of hell
crank levers 353 which are operated directly by
the keylevers instead of through a transfer mech
anism. ‘As shown in Fig. 7 the bell crank levers 05
are carried on a pivot shaft 354 suitably mounted
in brackets 355. To the depending arm of each
bell crank there is=secured one end of an indi
vidual spring 353,- the otherrend of which (not
shown) is attached to the frame. The bell crank 70
353 thus normally tends to rotate in a clockwise
direction due to the action of spring 353. Thus,
when a keylever is depressed, one of the bell crank
levers 353 is caused to rotate in a counterclock
wisedirection against‘ the action of spring 353 to 75
bring the right end of the horizontal arm 352 into
the path of the stop lug I36 on the unit rack 83.
The bell crank levers are held against displace
ment by spring actuated detent member 351 which
5 is a substantially U-shaped lever pivotally mount
ed on ‘a pair of pivots 358. This member 351 is
also provided ‘ with a shaft 358 on which are
ratchet 58. When the magnet is deenergized
spring 62 draws the pawl down, rotating the
ratchet 58 and feed roller 63 (both of which are.
a?lxed to the same shaft 64) one step in a well
known manner, thus feeding the tape to position 5 ,
it for the next perforating operation. Thus, the
tape is perforated in accordance with the op‘
mounted anti~friction rollers 36I individual to
and adapted ‘to cooperate with a laterally dis
1i)“ posed arm 362 integral with each bell crank 353.
The detent member 351 is normally biased against
the arms 362 by its spring the tension of which is
such as to overcome the tension of an individual
spring 356. Thus, when a stop bar-is selected it
15 will be held in the selected position by, the de
tent 351 until some other stop bar is selected.
General operation

scribed, a better understanding of the general op

~ rious operations incident thereto.
eration of the keylever 2. The energization of
electromagnet 82 effects the transfer of the selec
tion of Y-lever 52 to the stop bars 88 in the fol#
lowing manner. The operation of electromagnet
82 causes, by its attraction, the clockwise rotation
of armature lever 18 (Fig. 5) to in turn impart
opposite-rotation to transfer ball 15. Since the
selected Y-lever 52 has been oscillated to the left, 15'
its arm 61 is disposed below arm H of} the trans
fer lever 13. Thus, the operation of bail 15 causes
arm H to engage arm 61 and consequently lever‘
13 is rotated about the end of arm H as a ful
crum to effect the movement of the associated 20
stop bar 88 toward the right into the, path of lug
I36 on the unit rack 83.
The energization , and subsequent deenergiza
tion of escapement magnet I11 permits the mem
ber H4 by virtue of stop disc H5 and pawl I3I 25
to revolve 180°, thus imparting to cam II5 like

tion keys), one in the lower case and one in the
upper case, which characters may possibly be
of different thicknesses and thus require a differ~

the counting mechanism differently. The de

which near the completion of the key stroke ef
fects the closing of the main operating contact
I18 (Fig. 6). The time of closure of contact I18
60 is so regulated by the adjusting screw I81 as to
insure the prior selection of levers 31 and 52 and
punch interference bars 42.
The closing of contact I18, as noted in Fig. 16,
by“ the link- I52 is given a downward movement 40 ‘
to impart clockwise rotation to pawl member I33
about its pivot I38 against the action of spring
I44. ' The lateral portion I58 of pawl member I33
is thereuponmoved beneath the end of the unit
rack slide 85 to insure during the ensuing opera- 45 '- .
tion'vof the escapement means the engagement of
pawl I33 with unit wheel 88 prior to the disen
gagement of rack 83 to prevent the uncontrolled
escapement of unit wheel 88. ~
The unit wheel, which constantly tends to ro- 59-"
tate by reason of being fixed to shaft I III, is thus
released for rotation and the unit rack being free
to move is carried toward the right until the lug
I35 is intercepted by. one of the stop bars". At
this point the cam portion I63 acts upon the 55
follower roller I82 so as to reverse suddenly the
direction of rotation of the operating lever I55.‘
The unit rack slide 86 cannot at this time be
lowered because of the engagement oi’ its forward > -
extremity with the lateral portion I58 ofpawl-?o '
member I33. Lever I53, therefore, is causedto
rotate in a counterclockwise direction about the
pivot I54, thus causing the link I52 to be elevated
and escapement magnet I11. (Of course, it is un
derstood that the closing of the manually op

which in turn permits pawl member I33 to rotate

IOI, pinion I32 and gear 20! to matrix pointer
203. As succeeding character keys are depressed
the index hand or matrix pointer will be advanced
along the dial in amounts varying with the thick
ness of the matrices corresponding'to the key
Now, if it is desired to perforate and count an
upper case character it is ?rst necessary to de
press the shift keylever 8, in which event the mem-
ber l5 (Fig. 2) will be rocked rearwardly' and the
code bars i2 will assume their rearward position.
Since the shift operation is what is termed a
“function”, no counting operation is necessary
because there is no matrix corresponding thereto.
Therefore, since the perforating operation pro
ceeds as usual, it becomes necessary to disable the
counting mechanism.
To do this, an additional pair of permutation
bars H9 is provided which are operable only by
“function” keylevers, which are those keylevers
. that initiate the operations‘other than counting,
in which case the counting operation is not re
quired. Thus, when‘ a function keylever (as in
the present instance, the shift keylever 6) is op
erated, it e?ects through its associated horizontal
30 .bar Ill (analogous to bars 35 and 49), Figs. 2
and 16, the opening of the normally closed con
tact I22. Consequently, the closing of the main
operating contact I18 (which is operated invaria
bly) will, in this event, establish the circuits for
. the perforating magnet and transfer magnet only.
The energization of the perforating magnet ef
fects the perforating operation to thereby punch
and feed or step the tape in the regular manner.
It will be recalled that the purpose of always op
erating the transfer magnet simultaneously with
the perforating magnet is to effect the unlatch
ing of the operating contact I18, Fig. 6.
Thus, the depression of character keys follow»
ing the operation of the shift key will affect the
various devices in a manner similar to their op
eration prior~thereto, except that the counting
complish ‘this the elevator or end-of-line key in
depressed which, as already seen actuates keylever -
213 (Fig. 1'1) to effect through lever 21! the clos
ing of contact 285, and operation of rod 218. The
closing of contact 285 permits the electromagnet
M8 to become energized, the effect of which is
to relieve the pressure on‘the index hand or
pointer 2031to permit its return to its initial posi
tion. The operation-of rod 21! effects the release
of pawls 269 and 265 from ratchet 262 to permit 10:
the return of the pointers 2" and 254 to their
original position.
Since the elevator key is also a function key,
no code bar I2 is associated therewith and hence
the counting mechanism is not affected thereby. 15,
However, a perforation is made in the tape, the
effect of‘ which upon the line casting machine is
to initiate the operation of the elevator mecha
nism, thus causing the loaded assembly elevator
to be raised to the line delivery position, where- 20
upon the composed line of matrices and space
bands- is delivered to the casting position, in a
manner well known in the art to which the pres
ent invention pertains.

it is, of course, understood that the invention is
