In these machines, the composed line is trans

into 'the‘casting channel or so-called “?rst ele

the composed line-is advanced to the left by the
right hand ?nger, and in its advance picks up
the left hand ?nger and-carries it along there

carriage, the~left hand ?nger is restored to the
3.5. right by the customary adjustable stop on the
carriage slide‘which‘ locates it at the proper dis-‘
tance from the right hand ?nger. The ‘loose
mounting of the left hand ?nger is‘intended pri»
marily to enable the‘ transfer carriage‘ to ac
40 commodate itself to short lines, that is to say,
lines shorter than that for which thetwo ?ngers
are- adjusted. Thus, when a short line is de
livered to the transfer carriage, the leading ma
trix of. the line‘ necessarily stands some distance
45 away from the‘ left hand“ ?nger, but this dis
tance‘is immediately‘taken up during‘ the‘initial
movement of the transfer carriage, due to the
fact that the left hand ?nger is held "at rest
until ‘picked up by the‘ advancing ‘line. In this
50 way,- the two ?ngers are caused to approach each
other and: con?ne the line between them, reliance
being placed upon the above mentioned friction
device to maintain the ?ngers in this condition
until the line is taken from the carriage by the

which: the left hand finger is provided. The
requisite pressure for maintaining the‘ matrices
properly compacted in line during transfer is
supplied by a light {leaf spring mounted on the
long‘ left hand ?nger and which is adequate for
the purpose. In the embodiment illustrated, the 30
left hand ?nger is equipped with a pawl normally
held out of engagement with the teeth‘on the
carriage slide by a trip lever adapted‘ in the
course of transfer of the‘line to release‘the pawl
and permit it toengage directly with. the carriage 35
slide. Consequently, when the slide is moved to
the left in the‘ transfer of the line to the ?rst
elevator, the left hand ?nger is moved ‘by the
carriage slide itself, and not through the line of
, matrices, as heretofore. As the transfer carriage 40
reaches the end‘ of its line delivery stroke, the
pawl is disengaged from the slide, so‘ that upon
the return stroke of the latter, the left hand
?nger‘will remain stationary until it is picked up
by the adjustable stop which, as usual, deter
mines ‘the normal setting of the left hand ?nger
forlines of a given measure.
‘
‘
If the line to be transferred is of the proper
length for which the ?ngers are set, the‘ trip
lever will be actuatedwand the pawl engaged
with the carriage slide when the composed line
is raised between the two carriage ?ngers and
beforethere has been any relative movement be
tween the carriage slide and the left hand ?nger.
However, in the event that a line shorter than
55

that for which the ?ngers are set is positioned
between them, the right hand ?nger will move
the composed line toward the friotionally held
left hand ?nger, resulting in a relative movement
between the carriage slide and the left hand
?nger, but as soon as the leading matrix of the
composed line actuates the trip lever, the pawl
is released and the left hand ?nger instantly con
nected directly to the carriage slide, and this
10 before any movement can be imparted to the
left hand ?nger through the medium of the line
itself.

elevator to the casting elevator is effected by
means of a so-called transfer carriage compris
ing a horizontal slide or body portion B1 and two
line engaging ?ngers B2 and B3. The slide is
supported at its ends by a pair of blocks B4 and
B5 mounted in guideways B6 (Fig. 4) in the front
frame of the machine and is moved to-and-fro
by a power operated lever (not shown) but which
is connected to the slide through the medium
of a link B7 (Fig. 3). The right hand ?nger B2
is rigidly secured to the slide, whereas the left
hand‘?nger is loosely mounted with reference
thereto, being attached to a separate block B8
slidably arranged in the guideways B6 and hav
ing a guide rod B9 passing loosely through an open
ing in the other ?nger. The setting of the left
hand ?nger from the right hand ?nger is deter
mined by an adjustable stop 1310 carries by the
slide and which is adapted to abut against the
sliding block B8 in the line receiving position of
the carriage (see Figs. 1, 2 and 3). The stop B10
is held in its adjusted position by a ?nger oper
ated pawl b which cooperates with ratchet teeth
bll formed in the front face of the slide. The
?nger B3, or more speci?cally the sliding block
B8 on which it is carried, is provided with a fric
tion device in the form of a spring pressed plunger
B11 bearing against the smooth face of the ma=
chine frame just above the guideway (see Fig. 4).
The foregoing parts and their mode of opera~
tion are substantially as shown and described
in the Rogers Patent No. 795,936, or as may be
found in the commercial machines. In the com
75 mercial machines, when the transfer carriage is
The spacebands are supported by their
ears 7/ during assembly on a pair of horizontal
a pair of opposed narrower rails H1 on which
the matrices composed at the upper level are
supported by their lower ears :r. The lower ears
ac of the matrices supported at the lower level
pass beneath the lower rails H1 during their
passage through the transfer channel. Should
the, assembler elevator be slightly lower than 46
the transfer channel, the matrices composed at
the lower level will, as they pass into the inter
mediate transfer channel, be cammed upwardly
by the engagement of their upper ears with up
wardly inclined surfaces H2 formed at the top 50
of the upper rails H at their leading ends. If
the matrices composed at said level are somewhat
high, they will be cammed downwardly by the
engagement of their lower ears with downwardly
inclined surfaces H3 formed at the bottom of the 55
lower rails H1. With regard to the matrices com
posed at the upper level, they will, under similar
conditions, be cammed upwardly by the engage
ment of their lower ears with upwardly inclined
surfaces H4 formed at the top of the lower rail 60
or downwardly by the engagement of said ears
with downwardly inclined surfaces H5 at the bot
tom of the upper rails.
The spacebands are guided in the intermediate
channel in a pair of opposed recesses H6. the 65
bottoms of which support the matrices by their
ears 7!. Since the spacebands too, may be either
too high or too low as they enter the transfer
channel, the top and bottom surfaces of the re
cesses at their leading ends are inclined down»
wardly and upwardly as at H7 and H8, so that
the spacebands by the engagement of their ears
y with said surfaces will be cammed downwardly
or upwardly as the case requires.
Similar provision is made for effecting the prop

depending. ?ngers E8 and E", that at the‘ rear
being acted upon by a leaf spring I)6 screwed'to
the slide block B8 and which urges the pawl
rearwardly, and that at the front normally stand
at the lower level are supported by their upper
projecting ears 061. These rails are inclined up
ing in front of a nose portion F presented at
the upper end of a vertically arranged trip lever
wardly at their entrance ends, as at C2, for the
F1 pivoted in the left hand ?nger B3, and which
serves to hold the pawl E out of engagement with
er transfer of the composed line from the inter
mediate channel to the ?rst elevator. The first
elevator is equipped with a pair of opposed up
per rails 01, one in each of the front and back
same reason as the corresponding rails at the
10 entrance end of the intermediateichannel. Low
er down the front wall of the ?rst elevator is
formed with a recess C3 and the usual retract
able rail C4 on which the matrices composed at
the upper level are supported by their lower
15 ears, and here too, the upper face of the recess,
as well as the upper face of the retractable rail
at the entrance end of the elevator, are inclined
downwardly and upwardly respectively, as at C5
and C6, to insure the‘ proper entrance of the
matrices.
Opposed recesses C7, similar to those in the
intermediate channel and near the top of the ?rst
elevator, accommodate the ears y of the space
bands, and the top and bottom .faces of these
25 recesses are inclined downwardly and upwardly,
as at C8 and C“, at the entrance end, as in, the
case of the corresponding recesses in the line de

The lever F1 normally is retained in its pawl
holding position by a leaf spring F2 fastened to
the ?nger B3 and which engages at its upper end
against a protrusion F3 formed on said lever just
below its pivot point. Likewise, when the lever is 15
in this position, an offset portion F4, at its lower
end, engages a second leaf spring F5 to hold the
latter at the top away from the ?nger B3, the
spring F5 being secured at its lower end to the
?nger B3 on its inner or line engaging face.
20
According to the foregoing arrangement, when
a full line of matrices is raised by the assembler A
to the transfer level, the leading matrix at the left
engages the leaf spring F5 and cams it to the left,
tripping the lever F1‘ and releasing the pawl E,
which latter immediately moves rearwardly un
der the in?uence of the leaf springbs. As a re
sult, the nose portion E1 on the‘pawl engages be
tween a pair of ratchet teeth b1 on the slide B1,
so that when the slide is actuated to the left to 30
transfer the line, the left hand ?nger B3 is moved
directly by the slide rather than through the com~
It will now be apparent that should relative

elevator C and prior to the return of the trans

hand ?nger B3, is disengaged from the slide B1
in order that the ?nger will remain stationary
until it is picked up by the adjustable stop B10 to
insure its proper setting to receive the next line.
The disengagement of the pawl E is effected
through the medium of a long bar G (see Figs. 2,
3 and 4) mounted at its ends on the blocks B4 and
10 B5 of the carriage slide B1 through the medium of
a pair of pin and slot connections G1 and G2. The
slots are angularly disposed, so that when the
bar G is moved to the right relatively to the slide
B1, it will move forwardly into engagement with
the ?nger E7 on the pawl E to shift the latter out
of engagement with the slide, whereas when the
bar is moved to the left relatively to said slide
during the initial return stroke of the slide, it will
return rearwardly into normal position, where it
i.) stands clear of the pawl. The normal position of
the bar G is maintained by a tension spring G3
connected to the bar at its right end and having
an anchorage in the right hand slide block B5,
but when the transfer slide reaches the end of
iii its delivery stroke, i. e., when the line has been
transferred into the ?rst elevator, as shown by
the dotted lines in Fig. 1, a depending ?nger G4
on the bar G banks against the customary car
riage arresting set screw G5 threaded into the
30 front frame of the machine at the left end of the
guideway B6, actuating the bar G to the right
relatively to the slide B1 and against the tension
of the spring G3, with the result that the bar is
moved forwardly to disengage the pawl E from
the slide in the manner just described. The de
scent of the ?rst elevator with the composed line
frees the trip lever F1, which immediately, under
the action of the leaf spring F2, engages in front
of the depending ?nger E9 on the pawl to hold the
40 latter disengaged from the slide, so that the ?n
ger B3 will remain stationary until it is picked up
by the adjusting block B10 upon the return move
ment of the slide. As the line transfer slide com
mences its return stroke, the bar G is released
45 and is returned to its normal position under the
influence of the spring G3, the pawl E thus being
freed for engagement with the slide when the
next line is delivered to the transfer carriage.
Since the bar G extends the full length of the
Having thus described my invention, what I
claim is:
1. In a typographical composing machine, the
combination with a movable line transfer car
riage having two ?ngers to engage the line at
opposite ends, one ?nger being ?xed to said car
riage and the other movable with respect thereto,
of means operated by the composed line for estab
lishing a motion transmitting connection be
tween the movable ?nger and the carriage for
movement thereby independently of the line in
the line transfer operation.
2. In a typographical composing machine, the
combination with a movable line transfer car
riage having two ?ngers to engage the line at
opposite ends, one ?nger being ?xed to said car
riage and the other movable with respect thereto,
of means including devices carried by the mov
able ?nger and acting automatically to establish
a motion transmitting connection between said 20
?nger and the carriage for movement thereby
independently of the line in the line transfer
operation.
3. In a typographical composing machine, the
combination with a movable line transfer car
riage having two ?ngers to engage the line at
opposite ends, one ?nger being ?xed to said car
riage and the other movable with respect thereto,
of means operated by the composed line for
establishing a motion transmitting connection 30
between the movable ?nger and the carriage for
movement thereby independently of the line in
the line transfer operation, and means for un
locking the ?nger from the carriage when the line
transfer operation has been completed.
4. In a typographical composing machine, the
combination with a movable line transfer car
riage having two ?ngers to engage the line at
opposite ends, one ?nger being ?xed to said car
riage and the other movable with respect thereto, 40
of means including devices carried by the mov
able ?nger and acting automatically to establish
a motion transmitting connection between said
?nger and the carriage for movement thereby
independently of the line in the line transfer 45
operation, and means for unlocking the ?nger
from the carriage when the line transfer opera
tion has been completed.
5. In a typographical composing machine, the
50 slide B1, it will, of course, cooperate with the pawl ‘ combination with a movable line transfer car
E in any position of adjustment of the left hand
?nger. The pawl engaging portion of the bar G
is somewhat narrower than the ends thereof,
merely for the purpose of clearance, the wider
ends being necessary in order that the slots GI
and G2 will have SlliTlCiGIlt length to allow the
bar the necessary throw to effect the disengage
ment of the pawl from the slide.
It will now be seen that all of the pressure on
the composed line, which would otherwise be ex
erted if the frictional resistance of the plunger B11
had to be overcome, is entirely removed, so that
the matrices if necessary can move relatively to
each other without undue Wear, being held as
they are, only under relative light spring pres
sure.
In the accompanying drawings, the invention
has been shown merely by way of example and
in preferred form, and obviously, many variations
and modi?cations may be made therein which
will still be comprised within its spirit. It is to be
understood, therefore, that the invention is not
limited to any speci?c form or embodiment, ex
