Year: 1885

page_text: COMPLETE SPECIFICATION.
I ALFRED JULIUS BOULT of 323 High Holborn, London, in the County of
Middlesex, England, Engineer, do hereby declare the nature of the invention for
IMPROVEMENTS IN "MACHINES FOR PRODUCING RELIEF SURFACES FOR LETTER
PRESS PRINTING. (Communication from Ottmar Mergenthaler of Baltimore County
of Baltimore State of Maryland), and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:-
r
This invention is directed to the rapid and economical production of letter press
printing and consists in a machine to be driven by power and controlled by finger
keys, adapted to produce printing forms or relief surfaces ready for immediate use
thus avoiding the usual operation of type-setting and also the more modern plan of.
preparing by machinery matrices from which to cast the form.
By the use of this machine the operator is enabled to produce with great rapidity
printing-bars bearing in relief the selected characters in the sequence and arrange-
ment in which they are to be printed. In short the machine will produce printing.
forms or surfaces properly justified and adapted to be used in the same manner
and with precisely the same results as the printing forms composed of movable
type.
The machine embraces two leading groups of mechanism, first, those which form
a temporary changing matrix, representing a number of words, and second those
by which molten or plastic material is delivered to the matrix and discharged
therefrom in the form of printing bars. These two groups which will for con-
venience of reference be hereafter designated as the "matrix mechanism and the
casting mechanism are so combined that the casting of one bar may be carried
on while the characters are being designated and devices adjusted to adapt the
matrix for the production of the next bar whereby time is economized and the
capacity of the machine greatly increased.

The matrix mechanism resembles in many respects the indenting mechanism
described and shown in the application for Letters Patent filed February 10-1885
but differs therefrom among other things in having intaglio instead of cameo
characters.

page_text: The matrix mechanism embraces a series of parallel longitudinal matrix bars or
carriers cach containing at one edge a series of intaglio letters or characters, one or
more entire alphabets if demanded and also when required blank portions repre-
senting spaces between the words. These bars are adjustable independently so as
to bring the selected characters one in each bar, side by side in a single line and so
also as to bring the blank spaces of the appropriate bars between the groups of
characters forming words, the series of bars thus adjusted presenting jointly a
matrix adapted for the formation of a line of characters or words properly
punctuated and justified. The bars are lifted mechanically to their normal position
after the formation of each cast, and descending by gravity when released are
arrested respectively by stop-pins at the different points required to bring the
selected characters in a common line. The stop-pins of which there is a vertical
row for each matrix-bar are set for action by adjusting pins which are in turn
operated by the finger-keys.
The adjusting pins are mounted in a laterally movable frame so as to be
presented to the stop-pins of the various matrix-bars in succession as in the
previous machine. The stop-pins are mounted in a frame movable forward and
backward and combined with devices by which they are first moved backward,
after being adjusted in order to arrest the bars, and subsequently moved forward
and restored to their original positions preparatory to the designation of the
characters for another line.
After the matrix bars are stopped in their descent a pin is thrust through holes
in the entire series to bring the selected characters in approximate alignment, after
which a transverse blade enters notches in the backs of the bars and at the same
time clamping devices act to close the bars together and confine them in the precise
position desired thus completing the temporary matrix.
A sectional mold of the form of the desired printing bar closes adjacent to the
matrix bars with its open side in intimate contact therewith opposite the line of
selected characters: A force pump acting in connection with a melting pot and
heater, delivers type metal into the mold and matrix. As soon as the metal has
become sufficiently hardened the mold opens and the printing bar is delivered
therefrom.
In due course the various parts assume their normal positions and again operate
as described to complete the next bar. While the casting of one bar is in progress
and while the matrix-bars are locked in their adjusted position the stop-pins are
disconnected from the bars and restored to their normal positions so that the
manipulation of the keys may be continued in the meanwhile to set the stop-pins
for the arrest of the matrix-bars to produce the matrix for a second line this action
being also somewhat similar to that in the previous machine.
.
To permit the correction of errors caused by the striking of an improper key
means are provided for instantly restoring the adjusting pins stop-pins and indi-
cators to their primary positions so that action may be commenced anew.
The matrix-bars tapered laterally from end to end, are arranged alternately with
their wide and their narrow ends uppermost and have the characters arranged
thereon in the order of their width. At suitable intervals in the length of the bar
between the characters blank portions before alluded to as "spacing surfaces are
provided, these surfaces varying in width according to their different locations upon
tlie bar.
"
An indicating mechanism of novel character is provided to show the space
remaining to be filled in each line after all the characters allowable therein have
been designated.
Special devices are provided to operate in connection with spacing keys so that
a given space remaining to be filled at the end of a line may be taken up by
causing those matrix-bars which have been designated to prevent blank spaces in
the line to advance and present blank spaces of such width as may in each case be
demanded.

Matrix Bars. In proceding to construct the machine I first provide as
fundamental elements, the series of matrix-bars, B, B¹, the number of which should
equal the maximum number of characters and spaces to appear on any one
printing bar. These matrix-bars consist each of a metal strip tapered laterally
from one end to the other and provided in one edge with the series of recessed or
intaglio characters, a, and also with one or more blank spacing surfaces, b.
It is preferred to provide the bars as shown in Figs. 6, to 10, with transverse grooves
or recesses and to locate the characters in the bottoms of these recesses but the
characters may be formed directly in the edge of the bar. There may be any
desired number of characters in each bar for example, one or more complete
alphabets, together with the pumerals, punctuation marks, and symbols in coinmon
use.
The characters are disposed in a single column lengthwise of the bar and in
position to be read transversely thereof as shown, this arrangement permitting
single characters on adjacent bars to be assembled in position to read as a single
line. The characters are arranged in the bar in the order of their width, the
narrowest characters at the thin end, so that each occupies substantially the entire
width of the bar at the point where it is located.
This construction permits any character of any bar to be brought in close
relation to any character on an adjoining bar and thus secures the proper width
and uniformnity of spacing between characters in the same word.
Inasmuch as the lower case letters are of different.lengths or heights and extend
above and below the line different distances, it is found advisable to give. the
recesses or notches in which they are located different forms, as plainly represented
in Fig. 9. The bars are divided into imaginary spaces of equal length allotted
one to each other. Those letters which are located wholly above the line and which
extend upward the minimum distance such as-a, c, e, o, s, etc. have the walls or
recesses of their edges beveled backward as plainly shown.
Those letters which have stems extending upward above the line a maximum
distance such as, b, d, h, etc. have the upper walls of their recesses perpendicular
to the edge of the bar while the lower walls are beveled as shown. Those letters
which extend below the line the maximum distance as for example, p, q, etc. have
the lower walls of their recesses vertical while the upper walls are inclined. This
construction is adopted to reduce the width of the printing bar adjacent to the
characters and to prevent the formation upon the printing bars of raised surfaces
which would be liable to receive and give off ink at improper points. It is also
advantageous in that it permits the printing bar to be the more readily detached
from the matrix.
The matrix bars are divided into two groups or sets, B, and B¹. The first group
is arranged with the narrow ends uppermost, while the second group are arranged
with their wide ends uppermost as plainly represented in Figs. 5 to 8, the bars of
the two forins being alternated throughout the series when assembled in the
machine for reasons which will hereinafter fully appear. The fact that the bars of
one group have their wide ends uppermost, while the others have their narrow ends
uppermost, necessitates a corresponding difference in the arrangement or sequence
of the characters thereon, the letter W, for example appearing at the lower end of

page_text: the bars, B, but at the upper end of the bars B¹. Each matrix bar is provided. in
the rear edge with a series of transverse notches, d, one for each character and
space and is also provided in the middle with a corresponding series of perforations;
e, these notches and perforations being designed to co operate with the devices by
which the bars are aligned and held during the casting operation.
Having provided the series of matrix-bars I pivot each at its upper end to a
metal link, C, which is in turn jointed at its upper extremity to a supporting head
or plate, D, designed to slide in suitable guides and provided on one side with a
dog O. This dog is pivoted at its upper end and urged outward by a spring, f.
At its lower end it has a rearwardly extending finger, g, and a downwardly
extending finger h, each of which is beveled or inclined at the extremity. To those
heads, D, from which the matrix-bars, B¹, are suspended I connect flexible chains
or bands, E, the opposite ends of which are secured permanently to slides F.
Matrix Bar Connections.-Having provided the matrix-bars as above I arrange
them side by side in a vertical position first, a bar with the wide end uppermost
next a bar with the narrow end uppermost and so on throughout the series. The
heads, D, from which the bars are suspended I arrange to slide at their edges in
parallel vertical grooves formed in the faces of two guide plates, i, and i¹ which
are fixed permanently in position in the main frame as represented in Figs. 1-3—
4-25-26 and 27, the arrangement being such that the bars may rise and fall
independently of each other. The rear guiding plate ¹, is provided as plainly
shown in the several figures with notches or shoulders, j, to engage with the dogs Q,
on the sliding heads so that whenever a dog is permitted to operate it will act to
sustain the sliding head and its matrix-bar at the elevation in which they may
chance to be at the moment.
Between the guide plates i i¹, I locate a lifting head or yoke, P, which is
arranged to slide vertically and which loosely encircles the upper ends of the entire
series of sustaining links, C, in such manner as to engage beneath and support their
heads, D. The lifting head thus applied serves as a means of temporarily sustaining
the entire series of matrix bars, of lowering them simultaneously and of lifting
them after the casting operation to their normal positions. On reference to Fig. 4,
it will be observed that the upper rear edge of the lifting head, P, is beveled or
inclined to engage the lower ends of the dogs, Q, which are thus held out of action
so as to permit the heads and matrix-bars to rise and fall freely with the lifting
heads so long as they are supported thereon. When however the descent of any
head, D, is arrested by a stop-pin as hereinafter described, the lifting head, P,
descending from the dog, Q, will release the latter so that it may immediately
engage the plate, i, to prevent the further descent of the matrix bar in the manner
represented in Fig. 26.
The matrix-bars, B, having the narrow ends upward have no connection above
their heads, D, but the heads of the intermediate matrix-bars, B' have their bands
or chains, E, carried upward over stationary guide rolls, l, and thence downward to
their slides, F, which are arranged to travel in vertical grooves formed in the
opposing faces of guide plates, m, m³, fixed vertically in position in the main-frame
as represented in Figs. 3 and 25;
The descent of either bar, B¹, causes a corresponding ascent of its slide, F, and
vice-versa. These slides are employed in connection with the alternate matrix bars
to engage their stop-pins for the purpose of arresting the motion of the bars at the
proper points and are necessary in order to permit the use of one set of keys and
adjusting pins in connection with the two forms of matrix bar which it will be
understood by reason of the different arrangement of their characters, required to
be stopped at different heights in order to present a common letter at the printing
point as will hereinafter more fully appear.
Stop Pin Mechanism.-For the purpose of arresting the descent of the matrix
bars at the proper points to present their selected characters in position for use,
I employ horizontally sliding stop-pius G and G', the former to stop the bars B, and

page_text: .
the latter to stop the intermediate bars, B¹. The pins are arranged in horizontal
and vertical rows. The pins in each horizontal row represent the same letter of
the different matrix-bars while those in each vertical row represent the different.
characters and spaces of the same bar.
The pins, G, are made of such length that they may be projected beneath the
heads, D, of the bars, B, in order that they may stop said heads by direct engage-
ment therewith.
The pins, G¹, on the other hand, are made short so as to engage and arrest the
ascent of the slides, F, and thereby control the descent of the bars, B¹, indirectly,
through the bands E.
This arrangement permits all of the stop-pins which repre-
sent a given letter to be placed in line horizontally so as to be acted upon by a
single adjusting-pin, J, as the latter is moved laterally from one to another.
Were it not for the employment of the bands, E, and the slides, F, the stop-pins of
the bars, B, would require to be located at a different elevation from the stop-pins
representing like letters on the bars B³, and consequently it would be impossible to
employ a single series of adjusting-pins to present the same letter on the bars, B,
and B¹.
The entire series of stop-pins is mounted in a vertical frame, H, adapted to
be moved horizontally forward and backward by means hereinafter explained in
detail.
0.
Adjusting-Pins and Connections.-In front of the series of stop-pins I arrange
the horizontal adjusting-pins J, of which there is a single series arranged in a
vertical line or column in a frame, K, which is movable horizontally to and fro so
that the adjusting-pins may be presented, in front of the stop-pins of the several
matrix-bars in succession from left to right throughout the series as in the original
machine.
The adjusting-pins have their forward ends slotted vertically and mounted on
crank-shafts, L, which are sustained in bearing in the main-frame and rocked by
means of rods, O, extending from arms thereon downward to finger-keys, N,
arranged in a bank or group at the front of the machine.
The depression of any finger-key is followed by the operation of the corresponding
crank which in turn forces backward its adjusting-pin, J, causing the latter to force
rearward one of the stop-pins.
Each crank shaft L is encircled at one end by a
spiral spring fixed at one end thereto, and at the other end to the frame or other
bearing as shown in Figs 4 and 15 so as to turn the shaft forward and raise the
finger key when the latter is relieved from pressure at the same time restoring the
adjusting pin to its original position. By means of an escapement mechanism
hereinafter described the depression of cach key is caused to advance the frame
which carries the adjusting-pins, step by step, from the left toward the right.
At the depression of the first key the adjusting-pin operated thereby standing in
the position represented in Fig. 3, acts upon one of the stop-pins of the first matrix-
bar. As the finger key rises the escapement permits the adjusting pin frame K, to
move to the right, so that at the action of the second key the adjusting pin
operated thereby actuates a stop-pin of the second matrix bar and so on repeatedly
the result being that after a suitable number of keys have been operated stop-
pins will stand adjusted to arrest the motion of all the matrix bars, one pin for
each bar.
Stop-Pin Frame.-For reasons which will hereinafter appear it is not permissible
to have the stop-pins moved at once into position to arrest the bars.
After being designated and adjusted by the manipulation of the keys they are
moved backward in position to arrest the matrix-bars by a rearward movement of
their supporting frame, H.
.
This motion of the frame carries all the pins backward but as those which were
adjusted by the keys project beyond their companions, they alone are placed in
position to engage the heads, D, and slides, F, to stop the matrix-bars.

page_text: After the entire series of matrix-bars has been stopped and are sustained by
their dogs, Q, the stop-pins are disengaged and restored to their normal positions.
This is accomplished by means of the horizontally movable plate, I, which is per-
forated to receive and engage with the notched or shouldered ends of the stop-pins
in the manner represented in Figs. 2, 24, 26-27, etc.
This plate first moves backward independently from the frame, H, in which the
stop-pins are mounted and thus draws the entire series of pins backward in the
frame after which the frame and plate both move away from the matrix bars
carrying the stop-pins to a position in which it is impossible for them to effect the
stoppage of the bars; this being the position in which they stand at the time, the
operation of the finger keys is commenced.
After the proper keys have been manipulated and the proper stop-pins projected
rearward as shown in Fig. 28, the entire pin-frame again moves to the rear as
before in order to present the adjusted pins in position to effect the stoppage of the
bars.
The means by which the movements of the stop-pin frame and the retracting
plate are secured will be readily understood on reference to Figs. 2, 16, and 19
to 24.
The frame, H, in which the pins are mounted is sustained and arranged to slide
forward and backward on four horizontal pins, n, extending through its corners and
fixed rigidly to the main-frame.
An upright rectangular frame, o, encircles the frame, H, and slides closely in
vertical grooves in its sides. This vertically sliding frame, o, is provided at its four
corners with vertical slots, p, the upper and lower ends of which are inclined or
offset in opposite directions in the manner represented in Figs. 19, 20, etc. The
lower ends of these slots receive studs, r, projecting from the sides of the stationary
pins, n, as shown in- the various figures. When, therefore, the frame, o, is moved
vertically the slots and pins cause it to be shifted forward and backward by the
action of the pins within the inclined portions of the slots, and owing to its con-
nection with the pin-frame it causes the latter to move forward and backward in
like manner.
°
The retracting plate, I, is provided at its corners with ears having pins or studs, t,
to enter the upper portions of the slots, p, as plainly shown so that when the
frame, o, is depressed the upper ends of the slots will cause the retracting plate to
be moved backward away from the pin-frame to effect the retraction of the pins in
the manner before explained.
The following is the action of the parts in the sequence in which they occur.
When the frame, o, is fully elevated the pin frame stands in its forward position
with the retracting plate in contact therewith as shown in Fig. 19, so that the pins
may be adjusted through the action of the keys.
As the frame, o, descends the pins, r, acting in the lower ends of the slots cause
said frame, >, and the pin-frame to be shifted bodily backward so as to carry the
ends of the adjusted pins which project beyond the others into position to effect
the stoppage of the matrix-bars.
The downward motion of the frame, o, being continued the upper ends of these
slots are brought into play and serve to force the retracting plate away from the
pin frame whereby all of the pins are moved forward in the pin frame and restored
to their normal positions as represented in Figure 21.
The elevation of the frame, o, first closes the retracting plate against the pin
frauie as represented in Figure 22, and finally moves the pin-frame and plate for-
ward together to their original position to be again adjusted by the keys without,
however, interfering with the matrix-bars which are in the meantime locked in
position to permit the casting operation to be carried on.
Adjusting Pin Frame and Connections. As before mentioned, the adjusting
pins J, are mounted in an upright supporting frame, K, which is secured rigidly to,
and supported by a horizontal rack bar V, arranged to slide at its ends in bearings

page_text: in the upright portion of the main frame as shown in Figs. 4 and 15, so that the
frame, K, with the adjusting pins therein may be moved from right to left and left
to right to present the adjusting pins to the stop-pins of the different matrix-bars
as before alluded to.
This action is plainly represented in Figs. 2 and 3.
The upper end of the pin-frame, K, is guided by a fixed grooved bar u, as shown
in Fig. 4.
The cranked portions of the rock shafts, L, are of such length as to permit the
adjusting-pins, J, to travel freely thereon as the frame K, moves to and fro. For
the purpose of moving the pin-frame K, to the right and left as required I combine
therewith as shown in Fig. 48, two alternately acting weights, v and w, made in the
form of bars and arranged to slide vertically in opposite sides of the main frame,
the two bars being connected to cords x, passing over guide pulleys, y, and attached
one to the pin frame and the other to the rack bar by which the pin frame is
carried.
On top of the pin frame there is pivoted at the middle a transverse lever, z, the
opposite ends of which are arranged to engage beneath pins on the upper ends of
the weights, and w, alternately.
The end of the lever adjacent to the weight, v, is provided with a weight by
which it is held normally in a depressed position while its opposite end is connected
by rods, a, to a lever, a6, and treadle a.
In the normal condition of the parts the weighted lever z, stands in the position
shown in Fig. 48, one end maintaining the weight w, in an elevated position so
that it has no effect on the pin frame, K, while the weight, v, is permitted to urge
the frame toward the right. On depressing the treadle a7, and thereby moving the
lever, z, to the position indicated by the dotted lines in Fig. 48, the effect will be to
lift the weight, v, out of action and release the weight w, so that it may descend
and draw the pin-frame, K, to the left, this second or backward movement of the
frame being principally for the purpose of correcting the spacing or effecting
the justification of the lines as hereinafter explained. At the commencement of
the operation the adjusting pin-frame, K, stands at the extreme left of the machine
with the adjusting pins in position to act upon the stop-pins of the first matrix-bar
as before alluded to. Its movement step by step towards the right is secured by
means of an escapement mechanism, W, represented in Figs. 3-12-14-15 and 16,
constructed as follows: The teeth on the upper edge of the rack-bar, V, engage a
pinion, 61, fixed to a horizontal shaft, c¹, having bearings in the main frame. At
one end this shaft has fixed upon it an escapement wheel, d, which is engaged by a
vertically-swinging detent, e¹, the form of this wheel and detent being essentially
the same as those in the previous machine. The detent is urged upward by a
spiral spring f¹, and stands normally in the position indicated in Figs. 12, and 14,
its end abutting against one of the teeth of the escapement wheel and thus
preventing the movement of the rack-bar and pin-frame to the right. From the
detent el, a link g¹, extends downward and is connected by a rod to one of a pair
of levers, h³, located in the bottom of the machine, and provided in their forward
ends with cross-bars, j, resting beneath the entire series of finger-keys in such
manner that the depression of any key, whether to designate a character or spacing
surface will have the effect to depress the detent e¹.
The forward end of the detent has on its side two shoulders to engage the wheel.
The lower shoulder stands slightly in advance of the other and is separated
therefrom by an intermediate opening sufficient for the passage of the teeth
projecting from the side face of the wheel.
The tooth of the wheel stands normally against the lower forward shoulder as in
Fig. 14. When the depression of the key occurs the detent is depressed so that the
tooth of the wheel passes over the lower shoulder and encounters the upper shoulder
the wheel turning but slightly. When the key is released the detent rises and
disengages the tooth of the wheel, which. then' revolves until its next tooth in
turn encounters the lower shoulder of the detent, the rack-bar and the pin-frame

page_text: being thereby permitted to advance to the right a sufficient distance to
carry the
adjusting pins from the stop-pins of one matrix-bar to those of the next.
The arrangement of parts to permit the advance of the pin-frame, K, during the
rise of the finger key instead of during the depression is of advantage in that it
permits the lateral movement of the frame to occur at a time when the adjusting
pins are in their forward position so that there is no danger of their engaging
between or against the sides of the stop pins during their lateral movement.
Sustaining the Inactive Type Bars.-In the present machine all the matrix bars
when raised to the normal position stand above the clamping mechanism herein-
after described, and in the action of the machine those bars, if any, which are not
called into use at the moment are permitted to remain in their elevated position so
that the clamps passing thereunder will act only upon those bars which have been
designated by the keys for action. For the purpose of thus suspending the inactive
bars I provide a horizontally sliding bar, R, mounted in the main frame in position
to pass immediately beneath the heads, D, of all the bars in the manner plainly
represented in Figs. 4-25 and 26. This bar is urged forward in the proper
direction to pass beneath the heads by means of a weighted cord passing over
a guide pulley, a³, as shown in Fig. 25.
.
It is moved in the opposite direction, that is to say, from under the heads. by
means of an angular sliding arm, b³, which is connected to the adjusting-pin
frame, K, so that the movement of the pin-frame to the right in order to provide
for the stoppage of the successive printing bars is accomplished by the withdrawal
of the bar, R, so that the designated bars may descend. When the movement of
the pin frame ceases the bar, R, is permitted to remain beneath the heads of those
type-bars which have not been called into action so that they are maintained in
their elevated position while the remaining bars descend. This maintenance of the
inactive bars in the elevated position is of advantage in that it permits the clamps
to act on those bars only which are in use so that the clamps may be employed in
connection with the operative bars to determine the length of the mold, and the
casting as elsewhere described herein.
Spacing and Justifying Mechanism.-In practice it often happens that the
designated characters and the minimum spaces between the words are insufficient
to fill out the line while at the same time the remaining space will be insufficient
to admit a word or a syllable. In order to fill out or justify the lines under these
circumstances it is necessary to provide for the use of wider spaces. To this end
I provide for the movement of the adjusting pin-frame step-by step in a backward
direction that is to the left-and its stoppage in front of those bars which have
been designated for spacing so that the proper spacing keys may be actuated to
project stop-pins representing spaces of such width as may be demanded. To
secure this backward movement of the adjusting-pin frame and its stoppage in
front of the spacing bars only.
I provide the devices represented in Figs. 12 to 14. The rack-bar, V, of the
adjusting-pin frame is provided with a series of independent slides, t¹, working
through it from front to rear, their number and distance apart being the same as
the matrix bars. On the main-frame there is pivoted an elbow lever u in such
position that as the adjusting-pin frame advances to the right the slides, t', are
brought one after another opposite the upper end of the lever. This lever is
connected as in Fig. 12, to a pivoted arm carrying one end of the spacing key or
bar, U, which latter is extended across the front of the entire key board and
sustained at its opposite end by a second arm of like form as represented in
Figs. 1-2 and 3. The arms which support the bar, U, rest upon one of the cross
bars through which the escapement mechanism is operated as before described.
One of the arms which supports the bar, U, is also connected by a rod with one of
the vertical cam slides, a², which serves through the intermediate parts elsewhere
described to move the indicator, a distance equal to the width of the minimum
spacing surface,

page_text: As a result of the above action the depression of the spacing bar, U, is followed,
first by the operation of the lever, u¹, and its movement of one of the slides, t¹, to
the rear, second, by the advance of the counter or indicator to indicate the width
of a minimum space, and third, by the action of the escapement so that on the
release of the key the adjusting-pin frame will move to the right. On the main-
frame there is a fixed stop arm, w¹, against which the projected slides t¹, engage, one
after another during the backward movement of the adjusting-pin frame, that is to
say, its movement to the left so as to arrest the adjusting-pins the second time
opposite those matrix bars which have been designated for spacing.
The backward movement of the pin frame is secured by depressing the treadle,
Figs. 1 and 48, so as to bring the weight, w, into play as before explained. As the
frame, K, moves backward the stop-arm, w', first encounters that slide which was last
projected and thus stops the adjusting pins opposite the matrix bar last designated
for spacing.
After the proper key has been actuated to designate the space demanded on said
matrix bar the slide which bears against the stop-arm, w¹, must be pushed forward
out of engagement so that the pin-frame may continue its backward movement
until the next projecting slide encounters the arm and arrests the adjusting pins
opposite the next bar used for spacing. As the slides are thus returned one after
another to their normal positions the adjusting-pin frame will be carried step by
step to the left until the adjusting-pins have been presented opposite all the bars
designated for spacing.
For the purpose of restoring and disengaging the slides t¹, as above, I make use
of the elbow lever, 11, pivoted to the frame and connected by the rod, n¹, with a
cross-bar, o, sustained in a pivoted arm and arranged to be depressed by projections
on the under side of all the spacing keys. The upper end of the lever, l, is
projected laterally as in Fig. 14, in order to engage the teeth of a second escape-
ment wheel,, secured on the shaft which carries the main escapeinent wheel, k¹,
before described.
There is a separate spacing key to represent each spacing surface on the matrix
bar. These keys are connected with crank-shafts, adjusting-pins and stop-pins-in
precisely the same manner as the keys which designate characters, the action of
a spacing key being in all respects the same as that of a printing-key except that
it causes the bar to be arrested with a spacing surface at the aligning point in place
of a character.
The backward movement of the pin-frame and rack-bar turns the escapement
wheel in the opposite direction from that in which it first turned.
In operating the machine the spacing bar, U, is depressed whenever a point is
reached at which a blank or space is to appear in the. It will be remembered that
the operation of this bar advances the indicator and the escapement and projects a
slide, t¹, but does not affect the stop-pins. When therefore all the characters for a
line have been designated, stop-pins will have been projected to arrest all those
bars which are to present characters but not for the bars intended for spacing.
At this stage the operator referring to the indicator will perceive the amount of
space remaining to be filled at the end of a line, and knowing approximately or
precisely the number of spaces occuring in the line is enabled. to decide the width-
of the spaces to be introduced in order to fill the same.
When the proper spacing key is depressed to project the appropriate stop-pin,
the lever,, swings forward and at the same time that it restores and disengages
the slide to allow the further retreat of the pin-frame its upper end passes beneath
one of the teeth of the secondary escapement wheel, 21, so as to prevent the wheel
from turning any considerable distance and the pin-frame from moving while the
finger-key is down. When the key is released the lever, l, is drawn back from.
the wheel, r, and the pin-frame is moved to the left until the next projecting slide
encounters the stop-arm so as to bring the adjusting-pin opposite another
spacing bar..

page_text: By the recurrence of the above actions produced by repeated depressions of the
key representing the spaces of proper width be it greater or less the stop-pins are
so adjusted that the matrix-bars previously designated for spacing are stopped with
spaces of the required width between the aligned characters.
Indicating Mechanism. In order that the operator may know at all times the
space remaining to be filled in a line so that he may decide when to cease the
designation of characters and commence the justification I provide an indicating
mechanism which shows the aggregate width of the characters and spaces designated
by the keys.
This indicating mechanism is connected with and actuated by the rods, O, which
lead from the finger-keys to the pin mechanism as fully represented in Figs. 1, 2;
3, 4, 15, 29 and 30.
Each of the rods it will be remembered actuates an adjusting pin which
represents a given character or space on all the matrix-bars. Corresponding
characters and spaces have precisely the same width on all the bars. Each rod is
divided transversely as in Figs. 2 and 7, to permit the introduction of a vertical
slide, a³, which forms in effect a part of the rod and which works vertically through
openings in fixed guide plates, b², extending across the front of the machine above
the key board. Each of the slides, a², is provided on one side with an incline or
cam surface, c³, the "lift," or departure of which from the vertical is equal to the
width of the particular character or space brought into action by the rod and key
connecting with said slide. In other words each key is connected with a cam
slide having a lift which corresponds precisely with the width of the character or
space designated by the key.
These slides pass also through a horizontally reciprocating bar, d', which bears
against the inclined edge of all the cam slides when they are in their norinal
elevated positions as shown in Fig. 30, so that the depression of either key and
slide is followed by the movement of the bar, d², to the right a greater or less
distance. When the key and slide rise the bar is returned to the left by a
spring, e².
At one end the reciprocating bar carries a pivoted arm or dog, f³, which encircles
and engages frictionally with a horizontal indicator-rod, g³, sliding in guides and
carrying at one end a finger or pointer, 2, which traverses a fixed graduated
plate or scale, i². A second dog, j, pivoted to the main frame also encircles the
indicator-rod to prevent its retrograde motion. As the successive keys are
actuated their cam slides cause the bar, d² to reciprocate different distances and the
dog to repeatedly engage the indicator rod and move it to the right step by
step so that the pointer will at all times indicate on the scale the aggregate width
of the characters and spaces designated for use as well as the space remaining to be
filled.
Knowing the last mentioned space, and the number of bars designated for
spacing purposes the operator has only to depress the treadle and depress repeatedly
that spacing key representing the space which multiplied into the number of
spacing bars will give the space to fill the line.
This operation is exceedingly simple and may with slight practice be rapidly
performed.
After the completion of the line the indicator is automatically unlocked and is
returned to the left by a spiral spring, 1, enclosed in a tube into which one end of
the rod slides.
The unlocking of the indicator is accomplished by devices connecting with the
alarm mechanism now to be described.
Alarm Mechanism.—A bell, l', and a pivoted elastic striker, mt, are mounted on
the main,frame.
The striker is actuated by a spring, nt and is provided at the rear end with two
arms, o and p having studs which act on the feeding and locking dogs, f' and ja
of the indicator, to release them and permit the return of tho indicator at the

page_text: instant that the bell is sounded a second time to show the completion of the line.
The striker is lifted away from the bell and set for action by a vertical slide, q²,
having on its edge as in Figs. 29 and 31, an inclined surface to act against a rigid
arm on the striker. As the striker is lifted its arm is engaged and held by a
pivoted spring actuated elbow lever, 2, having a shoulder, s, on its side. The
indicator-rod, g², has at one end two projections, t and u², of different lengths.
When the line is at a certain distance from completion the stud, t, encounters the
detent lever, r³, and disengages its end from the striker, which falls until it
encounters the shoulder, 84, when it springs or yields sufficiently to strike the bell
but immediately rises out of contact therewith. As the line reaches completion
the stud, u², operates the detent lever and disengages the shoulder, s* whereupon
the striker is permitted to fall against the bell and sound the same a second time,
this action being followed by the release of the indicator dogs and the return of
the indicator as already explained. The vertical slide, q², before referred to as the
means of setting the striker has at its extreme upper end an incline, v³, on its side,
so that when fully depressed this incline will trip the detent, 2, and cause the
striker to fall, in order that the indicator may be returned to the starting point.
This is for the purpose of enabling the operator in the event of an error, to restore
all the parts to their initial positions, so that the line may be commenced anew.
The slide, q, is sustained normally in its elevated position as shown in Fig. 15, by
an arm, w, on a rock shaft, x, in bearings in the main-frame. This shaft which
extends in a fore and aft direction, also carries an arm, y², which acts against the
rack-bar, V, to return the adjusting-pin frame, K, to the starting point, at the left.
The shaft x², is further provided with an arm, z², united by a swivel-joint to an
arm, a³, on a transverse rock-shaft, 63, to which the reversing lever, M, before
referred to is also attached as in Figs. 3 16 and 17. In consequence of this
connection and the other connections already described, the lever, M, is caused to
serve the several purposes of moving the stop-pin frame and retracting plate of
restoring the indicator and of restoring the adjusting pin-frame. In short it
restores all the parts in an instant to the condition for the commencement of a new
line. The lever is maintained in its elevated position by means of a weight
applied to its rear end as shown in Figs. 16 and 17. This weight also over
balances the weight of the frame, o which shifts the adjusting frame so that it is
sustained in its elevated position.
Casting Mechanism.-The casting mechanism embraces as its leading features,
first, devices to align and clamp the matrix-bars, second, a sectional mold which is
closed in an operative position in front and against the matrix bars to present the
molten metal to the line of selected characters and give form to the resulting bar
or cast, and third appliances for melting the type-metal and delivering the same
forcibly into the mold and against the matrix-bars. Referring first to the
mechanism for aligning and clamping the matrix-bars, attention is directed
particularly to Figs. 1-11-32-33-34-45 & 49. A horizontal clamping bar, A¹,
extends as shown in Figs. 11-45 transversely of the machine in position to extend
across and against the rear edges of the entire series of matrix-bars when they are
in an operative position. This clamping bar has suitably formed arms which are
connected to the main-frame by means of dove-tailed guides as represented at, d³,
Figs. 1, and 45, whereby the bar permitted to move forward and backward to
and from the matrix-bars. At the opposite side of the position occupied by the
matrix-bars, I arrange the horizontal sectional mold X, X¹, consisting of two hori-
zontal bars one overlying the other at a distance therefrom equal to the thickness
of the required printing bar. Each section may be in one piece or several pieces
firmly united as shown.
Each of the mold sections or slides is formed as shown in Fig. 35, with a
shoulder f which serves as the ends of the mold.
Referring to Fig. 35, it will be seen that when brought into the relation shown
the two parts of the mold enclose a flat rectangular snac which is of a size

page_text: -
and form corresponding with that of the printing bars to be produced. By moving
the mold sections end wise with respect to each other the length of the mold proper
may be increased or diminished and thus the machine adapted to produce printing
bars of different lengths. By separating the sections in an endwise direction as
represented in Fig. 34, the mold is opened in order to release and permit. the
removal of the casting formed therein. As shown in Figs. 34 to 38 and also in
Fig. 45, the upper mold section is dove-tailed to and arranged to slide on the
under-side of a guide bar, h, bolted rigidly to the main-frame while the lower mold
section X is arranged to slide in like manner on a guide, also bolted to the main-
frame. The location of the two guides is such that when the mold is closed to an
operative position it will stand directly across the front or operative edges of the
series of matrix bars presenting its open side in front of the line of selected
characters. The opposite or rear side of the mold is closed by the flat mouth or
face of a melting pot, Y, which has a narrow slit or opening, for the delivery of
the molten metal into the mold directly toward the matrix-bars at the opposite
side thereof. The melting pot is fixed in the top of a box or chamber, C1, which,
also contains a burner, D', by means of which the pot is heated and the metal
maintained constantly in a molten condition. The box, C¹, is connected by hori-
zontal pivots, ³, at its lower side to the main frame so that it may tip forward and
backward to and from the mold.
At its upper side the box C', is connected by links, 18, to the upper ends of
levers, m³, on a transverse rock shaft, n³, mounted in the arms of the sliding
clamping bar, A¹, before referred to. It follows that as a result of this arrangement
that when the levers, m³, are moved in the direction indicated by the arrow in
Fig. 45, the clamping bar, A¹, will be moved forward so as to force the matrix-bars
tightly against the mold, after which the mouth of the melting pot will be drawn
firmly against the mold on the opposite side. The manner of operating the
levers, m³, will be hereinafter described. Their reverse motion will have the effect
of permitting the melting-pot and matrix-bars to separate from the mold in order
that the latter may be opened and the matrix bars readjusted.
In order to prevent the entrance of the molten metal between the adjacent faces
of the matrix-bars it is necessary that they shall be clamped firmly together
previous to the casting operation.
For this purpose I employ laterally acting clamps o³, and p³, which slide on
horizontal guides located at opposite sides of the machine on the face of the clamping
bar, A', as plainly represented in Figs. 11, 32-33 and 34. These clamps are con-
nected by horizontal pins q³ to the respective mold sections, so that when moved
inward to act against the sides of the bars they have the effect of carrying the mold
sections to an operative position. The inner ends or faces of the clamps stand in
line with the shoulders forming the ends of the mold as indicated by the dotted
lines in Fig. 40, so that when the inward movement of the clamps is arrested by
their contact with the matrix bars the ends of the mold are also brought accurately
in line with the faces of the outer matrix-bars so that the length of the mold must
coincide precisely with the length of the line of selected or assembled characters.
The employment of the matrix bars which are in use as a means of determining
the length of the extensible mold is an important feature of the invention. The
clamps, p³, are operated as shown in Figs. 11, 32, & 34, by links connecting them
with the upper ends of levers, 3, and s³, pivoted to the main wheel and actuated
by cam wheels, t³, the wheels being grooved to engage studs or rollers at the
extremities of crank shafts, u³, secured on the shafts ³, which carry the levers last
mentioned. The clamp, 2 is moved positively in both directions and under any
given adjustment advances always to the same position. The clamp, o³, at the
opposite side of the machine is actuated with a yielding pressure in order that it
may accommodate itself to the varying width of the series of bars which may be
brought into action between the two clamps. This yielding action of the clamp is
secured by mounting its operating arm ³ loosely on its shaft, v³, and connecting
the two by means of a spiral spring as shown in Fig. 49, or by any equivalent

page_text: yielding connection. Previous to the clamping of the matrix-bars, it is necessary
that they shall be aligned with great accuracy. For the purpose of effecting a
preliminary, alignment I provide the lateral clamp, o³, with a horizontal pin, ³,
projecting inward in advance thereof so that as the clamp advances toward the
bars, the pin will first be thrust through the holes in the entire series of bars until
it enters a hole in the clamp at the opposite side of the machine. This aligning pin.
is ordinarily pointed at the end and made of such size as to fit loosely within the
perforations of the bars. If demanded however, it may fit closely within the bars
and thus serve as the sole means of alignment. As the clamp recedes to release the
bars the aligning pin is withdrawn from them. In order to avoid the danger of
the bars swinging or moving laterally in such manner as to bind upon or engage
with the pin I make the face, y³, of the clamp o³, separate from the remaining
portion so that it may slide independently thereon as represented in Figs. 32, 34,
and: 49. This independent section commonly designated the "stripper-plate" is
provided with a friction spring bearing against the guide as represented in Figs. 33
and 34, or is combined with other suitable friction devices which will render it
necessary to apply a considerable force 'in order to effect its movement. As a
result of this construction the stripper-plate will remain in position and prevent
lateral movement of the matrix-bars during the backward movement of the clamp
and aligning pin in the manner represented in Fig. 33, thus ensuring the retraction
of the pin without difficulty.
The backward movement of the stripper plate a sufficient distance to permit the
descent of all the matrix-bars in advance thereof is secured by means of a
spindle, z, extending therefrom loosely through the clamp, 03, with a head at the
upper end as shown in Fig. 32.
This spindle permits the necessary independent or lost motion between the clamp.
and stripper plate but causes the former to retract the latter at the completion of
its movement."
As a means for perfecting the alignment of the bars vertically previous to the
closing of the clainping devices thereon I mount in the clamping bar, A', a
horizontal plate; a, arranged to slide forward and backward therein having one
edge adapted to enter the notches or indentations in the rear edges of the
matrix bars.
When forced forward into these notches the aligning plate, a, ensures the
accurate adjustment of the designated characters so that in the resulting cast they
will form a straight line. The plate, a, is advanced for action by a cam, b,
applied to the shaft of the clamp-operating levers, m³, the cam being so adjusted as
to advance the aligning plate before the clamping bar is closed tightly against the
matrix-bars.
.
Mention was previously made of the fact that the mold opens horizontally to
permit the delivery of the completed bar.
The upper section, X, of the mold is provided on its under face as shown in
Figs. 36, 37, 38 and 44, with a longitudinal rib, c, which enters the top of the
casting to retain the saine against lateral displacement.
:
This portion of the mold is further provided as shown in the same figures with;
a depending stud, d, which enters the upper side of the casting to ensure its
passage end wise with the upper portion of the as the latter is opened.
When therefore the mold is open the casting is carried to the right, adhering
beneath the upper part of the mold. When the casting has been carried entirely
clear of the lower part of the mold its delivery is effected by means of a plate, e,
pivoted as shown in Figs. 1 and 11, to swing in a vertical direction, its position
being such that as it descends its edge will engage the rear edge of the bar and
drive the same downward away from the top of the mold.
Each casting thus delivered falls upon a shelf or support, f' as shown in Fig. 34
in advance of a pin, g', extending to the lower part of the mold at the opposito
side of the machine,

page_text: As the mold recloses the pin, g' will push the casting formed at a previous..
operation endwise from the shelf, f, each casting being delivered in rear of the
one previously formed so that they push one another from the machine..
The delivery plate, e, is connected in rear its pivot to a rod, , which serves as
a weight to maintain the forward edge of the plate normally in an elevated.
position and which has its upper end provided with a head and extended through
an arm or guide on the lifting head, D, by which the matrix-bars are lifted.
1
As this head completes its upward movement' so that the matrix-bars assume
their normal positions. it lifts the rod, and causes the same to operate the
plate e¹.
In order that the printing-bars may have flat faces and a uniform height it is
deemed advisable although not absolutely necessary to plane or dress their lower
edges or bases.
10
For this purpose I mount on the main frame a depending knife or cutter,, as
shown in Figs. 1-11, and 34, in such position that the base of the casting will be 18
carried past its edge in the act of delivery.
4
In this connection the rib in the upper part of the mold is an important feature
in that it retains the casting securely and causes it to be carried' in a right line
past the cutter.
For the purpose of preventing the accumulation of metal at the delivery mouth 20
or outlet of the melting pot, I provide the lower portion of the mold with an
upright blade or wiper, , as shown in Figs. 34, 39, 40, and 41, usually a thin
plate or spring steel which is carried over the mouth of the pot as the mold is
opened and closed.
In order to insure the speedy action of the apparatus and the formation of a-25
perfect cast, I propose to employ in connection with the melting pot a pump or
forcing apparatus of any suitable character to deliver the metal therefrom into
the mold.
I recommend for this this purpose as the most simple and reliable known to me.
at the present time, a pump of the character represented in Fig. 45.
The delivery duct or channel, 3, of the melting pot Y, in the form of a fine slit
of considerable length is extended downward to the bottom and terminates in an
upright cylindrical chamber provided near the top with an inlet opening, n³,
through which the metal enters the same.
30
In the top of this chamber there is mounted a vertically reciprocating piston n. 35
When this piston is raised above the opening, mt, the metal passes thereunder,
When the piston is depressed it passes and closes the inlet opening and delivers
the metal through the opening, j³, to the mold.
The depression of the piston is effected by means of a spiral spring of, applied
to its upper end as shown in Figs. 1 and 34, this use of the spring being advan 40
tageous in that it ensures the application of a constant pressure and also in that
it avoids the danger of breakage which would otherwise arise in the event of the
metal being solidified beneath the piston as at the commencement of operations.
The elevation of the piston is effected by means of an arm, p* mounted on a
rock-shaft having a depending arm, q' the lower end of which is acted upon by a 45
lifting cam,, as plainly shown in Fig. 45.
For the purpose of increasing the capacity of the machine I propose to provide
the frame adjacent to the molds with passages, s', through which water or other.
cooling mediums may be passed to reduce the temperature of the parts.
Details of Driving Gear.-The machine receives motion primarily through a 50
band pulley, c, which revolves loosely on a tubular shaft, d³, carrying a fixed
crank arm, e³.
The inner face of the pulley carries a stud or projection, f5 while the crank
carries an axially sliding pin g³, designed to engage the stud for the purpose of
imparting motion from the pulley through the crank to the tubular shaft.
The pin, go, is notched transversely so that when it stands in the position shown
it will permit the stud to pass and the pulley to revolve without driving the shaft. -
55

page_text: The clutch pin, g³ is attached to an arm which is in turn connected to a rod or
spindle, sliding longitudinally within the tubular driving shaft.
13
The inner end of the spindle is connected by a pin passing through the slits in
the shaft to an external collar, j³, which is grooved circumferentially and connected-
by a pin or its equivalent to a controlling or shipping lever, 3, the notion of this
lever in one direction serving to engage the clutch pin and set the shaft in motion,
while its movement in the opposite direction effects the disengagement.
*
.
The shipping lever is operated in, the first instance to engage the clutch by
means of a hand,lever, Z, which extends to the front of the machine in position to
be operated by the attendant. The parts are held in connection for the proper
length of time by means of a wheel, 15, acting against a roller at the lower end of
the shipping, lever, this, wheel being provided in one side with a notch into
which the roller may fall as shown in Fig. 46 to permit the disconnection of the
clutch. A worn, wheel. m, applied to the shaft of the wheel, 75, is turned by a
worm on the end of the driving shaft. When the hand lever Z, is operated to
engage the clutch, motion. is: communicated from the shaft to the wheel, 15, which'
is at once turned so as to carry its notch away from the roller of the shipping:
lever, the effect of which is to retain the clutch in engagement until the wheel 15,
has made a complete revolution and again brought the notch beneath the roller
whereupon the parts,automatically disengage. The other parts of the machine are
so timed that this single rotation completes the production of a printing bar.
The shaft, A3, which carries the wheel, 15, also carries a cam, r, before alluded to,.
for, operating the pump. To effect the tilting of the melting-pot as before
described, the wheel, 13, is provided in one side as in Fig. 45, with a cam groove, no,
which engages a roller on a lever, o, the lower. end of which is connected by a
rod, p to the lever, m³, which actuates the main clamping bar, the melting-pot and
the rear aligning bar. To effect.the automatic adjustment of the stop-pin frame
and retracting plate which it will be remembered are operated from the lever, M,
as shown in Figs. 1 and 16, I connect the said lever, 5, which extends downward
to one end of a lever which is in turn pivoted to the main frame and raised and.
lowered at suitable intervals by means of a can also mounted on the shaft
carrying the cams before alluded to.

The lifting head, P, is, carried as shown in Fig. 3, by an arm t³, sliding in a
dove-tailed groove in the upright portion of the main frame. It is sustained and
elevated to lift the bars by means of a chain u³ attached to and arranged to wind
upon a pulley vs, mounted on a horizontal shaft in the top of the main frame.
This shaft is provided as shown in Fig. 1 with a pinion, w³, operated. by a vertical
rack-bar ³, the lower end of which is attached to an operating lever, y³, lifted.
at proper intervals by a cam ; mounted on the shaft, A³.
It will be observed that all of the driving cams and wheels are mounted upon
the single transverse shaft.

Operation. The operation of the machine as a whole is as follows: The parts
stand normally in the position represented in Fig. 1, the head, D, being in its:
elevated position and the entire series of matrix-bars suspended thereby at their
highest elevation. At this time the weight, v acts to urge the adjusting-pin frame
toward the right, the indicator mechanism. stands at zero, the alarm mechanism is
set for action and the stop-pins stand in their normal positions that is to say in
line with each other as represented in Figs. 22 and 24. The operator now depresses
in: succession the various keys representing the characters to be employed in the
order in which they are to appear. At the termination of each word or at other
suitable points he depresses the spacing bar, U. At the depression of the first key,
the corresponding adjusting pin forces backward the appropriate stop-pin to arrest
the motion of the first bar. When the key is released the adjusting pin frame moves."
toward the right thus bringing the adjusting pins opposite the second matrix bar so
that at the operation of the second key the stop-pin to arrest the second matrix-barr
is in turn projected to the rear. This operation is repeated until a suitable number
of spaces and characters have been designated. The aggregate value in width of
.

page_text: the characters and spaces thus designated will appear on the indicating mechanism
at the front. At a suitable time near the completion of the line the alarm
mechanism will give notice that the line is nearly completed and the operator,
inspecting the indicator will determine whether or not there is sufficient room
remaining to be filled by additional letters or characters. If not he observes on
the scale the width of the space to be filled and knowing the number of bars which
have been indicated for spacing purposes he presses the foot lever in order to
permit the movement of the adjusting-pin frame to the left, and repeatedly depresses
the particular spacing-key representing a spacing surface of suitable width. The
result of this action is to cause the projection of the stop-pins representing spaces
on the bars which have already been designated for spacing. At the completion.
of this operation there will be a sufficient number of stop-pins projected to arrest'
all of the bars which are to be called into use, but as yet the pins do not project
sufficiently to the rear to effect the stoppage of the bars. The operator now
depresses the lever, the effect of which is to set in action the automatic mechanism.
The first effect of this action is to cause the stop-pin frame to be moved rearward
in order to bring the rear ends of the adjusted stop-pins in position to arrest the
matrix-bars as represented in Fig. 20.

The lifting head, D; now commences its descent lowering the entire series of
matrix-bars which are individually arrested by their respective stop-pins in such
position as to bring the selected characters in the common line opposite the mold.
As the movement of each bar is arrested the lifting-head descending therefrom
permits the dog, Q; of said. bar to engage the rear guide plate i¹ in order to sustain
the bar after the disengagement of the stop-pin. After the matrix bars have been
adjusted the clamps p and o³, advance from. opposite sides to clamp the bars
between them. The clamp preaches its limit of movement in advance of the
other,so that on one side the series of bars stands always at the same point. The
clamp o continuing its movement applies a yielding pressure to the series of bars
which are thus confined snugly together irrespective of their number or width.
As the clamp o, advances, the aligning pin thereon is advanced through the bars
whereby they, are brought to substantially the required adjustment previous to the
action of the clamps thereon. At or about the time that the lateral clamps act on-
the barsithe aligning bar or blade a*, enters the grooves in their rear edges thus
perfecting the alignment. This action is immediately followed by the advance of
the clamping bar, A¹, from one direction and of the melting pot from the opposite
direction: At this time it will be perceived the matrix-bars are locked firmly in
position on all and against-the mold. sides with the mouth or delivery post of the
melting-pot, also in intimate contact with the mold. Immediately after the fore-
going operation the piston ndescends delivering the molten metal forcibly into
the mold where it immediately assumes the form of a printing bar the edge of
which bears in relief the letters or characters in the sequence and arrangement in
which they are to be printed.. The melting pot and clamping bar, A, and the
aligning bar, at now retreat and at or about the same time the lateral clamps are.
moved apart withdrawing the aligning rod or. pin from the bars. The retraction.
of the lateral clamps is accompanied by the opening of the mold the upper portion
of which carries the newly formed bar to one side of the machine where it is
detached from the mold by, the plate cas before explained. During the performance
of the casting operations above described. the retracting plate, K, was moved in such
manner as to draw all the stop-pins backward within their supporting frame. so
that they no longer engaged the heads and slides of the matrix bars. which latter
were thereafter wholly sustained by the dogs,.Q. After the retraction of the pins
as above stated the pin frame is moved.bodily forward carrying the entire series
of stop pins to their normal position so that the operation.of the finger keys to
designate the characters for the second, line may be carried on without interfering
with tlie casting of the first line.

Modifications. While I prefer to employ continuous or rigid matrix bars as
herein before described it is to be distinctly understood that I may substitute™

page_text: therefor bars composed of short sections joined together after the manner of a chain,
these jointed bars being adapted for operation in connection with the other parts
of the machine in substantially the same manner as the rigid bars herein before
described. It is also to be understood that in place of the matrix bars I may
substitute in connection with the casting mechanism matrix-wheels. While
practical experience. has shown that molten type metal is the best material known
in the art at the present day for the formation of matrix-bars it is to be understood
that I may substitute therefor any plastic material adapted to be forced into the
mold for the formation of printing bars and this whether the material hardens or
solidifies within the mold or whether it requires additional treatment such as
baking after delivery therefrom.
The essence of this invention lies in the use of a casting mechanism in combination
with a changeable or convertible matrix controlled by finger keys and the mechanism
may be greatly changed in detail.
