Improvements in Matrix-making Machines.
We, ALBERT JOHN KLETZKER, and JOHN GEORGE GOESEL both of No. 304,
North Eighth Street in the City of St. Louis, State of Missouri, United States of
America, Gentlemen, do hereby declare the nature of our said invention, and in
what manner the same to be performed, to be particularly ascertained in and by the
following statement :-
Our invention relates to machines for producing matrices, from which to make
stereo-type or electro-type plates for printing, machines for producing matrices, for
the purposes specified, intended to replace the forms of individually-set type, as in
ordinary practice, in book and newspaper work.
The object of our invention is to construct a matrix-making machine, simple and
convenient in operation, and adapted to fulfill, in all respects, the conditions as
provided for in a form of type for the production of printing-plates-i.e., capable of
variable spacing for (first) the different space occupied in the line by different
characters or letters, and (second) the inter-word spacing for the justification of the
line; capable of a blow of a uniform pressure being given to the dies, so as to
produce a matrix-plate, from which a printing-plate can be taken, having a plane
printing surface; adapted to make perfect alignment; capable of conveniently
changing the different fonts of characters; as, from lower-case to capitals, etc.;
capable of making matrix-plates of variable column-widths; adapting the matrix-
plate to be re-traced for the correction of mistakes; and capable of variable spacing
between lines, corresponding to solid set, or single, or double-leaded matter.
Our invention consists in the novel mechanism, hereinafter described, for giving
variable degrees of movement to the matrix-board carriage, corresponding to the
line-space required for different letters or characters; the mechanism by means of
which, in the operation of the same key, the degree of movement of the matrix-
board carriage required for the line-space of ordinary letters will be changed, so as
to be proportioned to the line-space required for the corresponding capital letters;
in the mechanism for making variable spacing between words; in the mechanism
for indicating how much line-space there is left unoccupied on the matrix-board;
in the means for producing the impression on the matrix-board by a force
independent of that applied to actuate the key operating the desired die; in the
arrangement, by which is brought into action the mechanism for producing the
impression; in a new form of die-holder and mechanism for operating the same,
whereby perfect alignment is obtained; in mechanism for bringing into position the
different fonts of type to be acted on by the impression-giving device; in a
specially-formed die-shank, to accommodate the same, insuring the alignment of the
individual dies; in an arrangement whereby the die-holder proper is made
removable, so as to be replaced by other similar and interchangeable oncs containing
different kinds of fonts of dies; in the mechanism by means of which, by depressing
the keys, the different dies are successively brought into the proper position to be
acted upon by the impression-giving device; in the arrangement of the framework
for the reception of the movable parts; in the arrangement of the sliding matrix-
board carriage, and the escapement mechanism connected therewith; in the
mechanism for operating the signalling bell, and in its arrangement in relation to
the sliding carriage.

In the following description, we have made use of both letters and figures, in
making reference to the different parts of the machine, endeavouring, in all instances,
to confine the letters to the stationary framework and principal parts, and the
figures to the movable parts, as illustrated in the drawings. In some instances, the
figures have been duplicated, in indicating the lines on which sections have been
taken for other figures. In all such instances, however, the figures indicating the

page_text: lines on which the sectious have been taken are accompanied with an arrow, which
indicates the direction in which the section, as shown by the figures to which it
refers, should be viewed.
As illustrated in Figs. 1, 2, and 3, the machine as a whole is supported on the
base-plate A. To the base-plate A, are secured the standards a, which support
the raised frame-work B, with the laterally-extending spanning-arms or girders B¹,
(see Figs. 2 and 3), the standards b, which support the stationary carriage-frame C
for the matrix-carriages, the standards c, which support the platform D, and the
several standards and bracket for the shaft and spindle bearings, as d, e, f, g, h, i, etc.
To the raised frame-work B, are secured the supports, bearings, etc., o, p, q, s, etc.,
for the various working parts relating to the stamping or punching device, and
the pivot-bearings u, v, and r of the spindles for the die-holder and operating fork-
lever.
The stationary carriage-frame C is fastened to parts b, so as to be adjustable, not
only in height, but, also, in position (Fig. 1). It is provided longitudinally with
slide-ways, to which the intermediate carriage E is fitted, and on which E can be
moved. Superposed, and moving at right-angles to E, is the matrix-carriage or
matrix-table F receiving the matrix-board, and moving in proper position for letters,
spaces, and sundry characters, by the force of a spring acting on an escapement
mechanism connected to the intermediate carriage E.
The raised platform D, fastened to posts c, acts as a guide for the vertical key-
stems, and as a support for the brackets of the keys designed to operate the
font-changing mechanism.
As shown in Figs. 1, 2, and 3, the machine, as a whole, is operated by a number
of key-levers, which extend from the front of the machine to a convenient distance
toward the back, their forward ends resting immediately beneath the key-board
platform D. To each key-lever is attached, by a hinge-joint, a vertical stem
passing through holes in the platform D, being guided in them and bearing at their
upper ends a knob or finger-button, each marked with the letters or characters
corresponding to the die, the key to which it is connected is intended to operate.
The bank of key-levers on one-half of the machine (Figs. 3 and 10) is divided into two
series, one of which is a duplicate of the other. All the key-levers are fulcrumed,
approximately, midway in their length (see 1, Fig. 1), on the support d, extending
across the width of the machine, (Figs. 2 and 3). The support d is transversely
slotted out, for the reception of the key-levers, to keep them at regular distances
apart.
The fulcrum-rod d', being thrust through holes in the key-levers, 3 and 4, acts as
a fulcrum-pin for each of them.
As indicated in the several figures, particularly in Fig. 19, the dies are distributed
in several rows in the die-holder, the number of which may vary with the number
of characters required. For illustration, we have adopted three-for lower case,
one; for upper case, a second one; and, for figures and other signs, a third one.
Referring to Figs. 4, 5, 6, 8, 9, 10, and 11, the circular rod 103 extends trans-
versely over the back ends of all the key-levers, 1, 2, 3, and 4, so that, when any
one of the keys is depressed, the rod 103 will be lifted. The two ends of the
rod 103 are provided with pins which rotate in the projecting ends of the two lever-
arms 102, which are rigidly secured to the rocking-shaft 101 journaled at either end
in the bearings in brackets f. To the shaft 101, is secured the lever-arm 100, the
free end of which is provided with a pin or screw fitting freely in a slot at the end
of the link 99. See Figs. 8 and 9. The other end of the link 99 is joined to a pin
fastened to the disk 98, which is rigidly secured to the oscillating shaft 96, to which
are also fastened the two levers 95. This shaft 96 extends over the whole length
of the carriage-frame C, with journal-bearings at both ends. In the ends of the
levers 95, parallel to the shaft 96, is secured the rod 97. This rod 97 fits loosely
in a hole in one end of the sliding-bar 76, which slides freely in the guide-blocks 74
secured to the escapement-frame 73, the two ends of the latter being screwed to
projecting ribs of the opposite side walls of intermediate carriage E. See

page_text: Figs. 4 and One end of the thick part of the sliding-bar 76 is formed into the
detent 76', which engages in the teeth 81' of the wheel 81, or releases them under
the oscillation of the rod 97 in all the positions which the intermediate carriage E
may assume on the carriage-frame C.
To the bar 76, is secured the bearing-block 77, which receives the pawl-arm 78.
The free end of the pawl-arm 78 is formed into the detent 78' (see Figs. 4 and 5),
alternately engaging and disengaging the teeth 811 of the escapement-wheel 81,
according to the action of the sliding bar 76. When detent 781 is engaged in the
teeth, the center of bearing 77 is in the center of escapement-wheel 81, and it can,
therefore, move concentrically with the latter.
The two detents 761 and 78 are so placed, one in relation to the other, that,
when one is engaged in the teeth of escapement-wheel 81, the other is disengaged
from it. The escapement-wheel 81 is idle on the hub of gear-wheel 85, while the
ratchet-wheel 82 is fastened to it, so that 85 and 82 move together. Ratchet-
wheel 82 and escapement-wheel 81 are connected by means of pawl 83 screwed to
the face of 81, spring 84 holding pawl 83 in contact with the teeth of 82.
Escapement-wheel 81 can, therefore, only move in one direction, as shown by
arrow in Fig. 4. The wheel 85 rotates idly on the axle-pin 90, which is rigidly
held in a hub on escapement-frame 73. See Figs. 6 and 4. The wheel 85 gears
in the wheel 86, which is rigidly secured to, and turns with, one of the gear-
wheels 87. Both wheels 87 are idle on the axle-pin 89, which is securely held in
the upper hub of the escapement-frame 73. The wheel 87, on the other end of
axle-pin 89, gears in the wheel 88, which is rigidly secured to spring-drum 91, the
latter being idle on axle 90. To the drum 91, is secured one end of spiral-band
spring 92, the other end of which is rigidly secured to the exterior casing 93,
which is fastened to frame 73, and, therefore, stationary to it (Fig. 5). To the
under side of the matrix-carriage F, is fastened (see Figs. 4 and 6) the double-
rack 94 gearing, at the same time, in the two wheels 87.
When free to act, spring 92 rotates drum 91 and gear-wheel 88 idly on axle 90,
wheel 88 transmits its motion to one of wheels 87, and, through it, to the double
rack 94 and matrix-carriage F. The motion of the rack is transmitted to the pair.
of wheels 87 and 86, the latter imparting its motion to wheel 85 and ratchet-
wheel 82, from which the motion is transmitted, through pawl 83, to escapement-
wheel 81, where. it is regulated by the joint action of the sliding-bar 76 and
escapement-pawl 78. In pushing the matrix-carriage back to start a new line, the
rack 94 will rotate wheels 87, which, on one side of escapement-frame 73, through
wheel 88, will wind up the spring 92. On the other side, gear-wheels 87 and 86
will transmit their motion to wheel 85 and ratchet-wheel 82, which will move
under pawl 83, leaving the escapement-wheel 81 stationary. In a state of rest,
the normal position of the bar 76 is with the detent 78' in engagement with the
teeth of the escapement-wheel 81, being prevented from moving by the stop-pin 80
secured in proper position on the guide-block 74. When the bar 76 is thrown to
the right, by the action of the intermediate mechanism described, in depressing
any one of the keys (see Figs. 8, 9, and 4), the detent 761 is brought into engage-
ment with the teeth of the escapement-wheel 81 and the detent 78¹ released
therefrom, when the pawl-arm 78 will fall by gravity through the distance of one
or several teeth of the escapement-wheel 81. Reversing the motion of the slide-
bar 76, by releasing the depressed key, detent 78¹ will re-engage, in its lower
position, the teeth of escapement-wheel 81, while detent 76' will be withdrawn
from them, and wheel 81 will move until the extremity of pawl-arm 78 meets
stop-pin 80.
For the purposes of this machine, it is necessary that all spaces in the line of
the different characters employed should be referred to one common unit, which
in our case is the distance the matrix-carriage travels while the periphery of the
escapement-wheel moves the distance of one tooth. This distance may be made to
vary, for letters of different thicknesses, by substituting for gear-wheels 85 and 86
other similar wheels of different relative diameters. We will call the distance

page_text: travelled by the matrix-carriage proportional to one tooth of the escapement-
wheel the unit-space, and we make the space, in the line, of all letters and
characters, a multiple of this unit-space. For instance, we make the line-space
occupied by the letter "i" and most of the punctuation marks and all similar
characters be equivalent to unit-spaces; f, 1, t, s, and similar characters, three
unit-spaces; of a, b, and equivalent characters, and letters, four unit-spaces;
F, J, L, etc., five unit-spaces; m and w and A and B, and equivalent capital
letters and other characters, six unit-spaces; and M and similar characters, eight
unit-spaces: These proportions are, however, subject to changes, according to
style of the alphabet employed, or to the dictate of custom or fashion.
In system-
atizing the spacing of letters and other characters in this manner, it is found that
nearly one-half of them require a similar and uniform line-space, while, for the
other half, the spacing varies. For this reason (Figs. 8 and 10), the key-levers
are divided into two sets, 1 and 2. Levers 1 are made to operate the rod 103 and
escapement mechanism only, and the other set, 2, being longer, are made to operate
mechanism whereby the relative fall of the pawl-arm 78 is 'regulated according
to the line-space required by the particular letter or character to be stamped.
In addition to the above, two key-levers, 3 and 4, are provided for spacing
only. Lever 3, for the production of unit-spaces, and lever 4, for the ordinary
spacing between words, which spacing in the machine, as illustrated, is made
equivalent to the line-space of the letters of the alphabet, but which may be
made to vary from this spacing, if found desirable.
To the pawl-arm 78, is secured the laterally-projecting pin 79 (see Figs. 4 and 5),
so that, in falling, it will strike the plate 75 sliding in the guide-blocks 74. On
plate 75, are formed steps, which, when brought to the path of pin 79, will arrest
the fall of the pawl-arm 78, so that detent 78 will engage the teeth of the escape-
ment-wheel a distance of one, two, or more teeth from its highest position acquired
in its upward movement, which is determined by the stop-pin 80.
The rod 72, passing through a slot in the plate 75, rocking-shaft 70, with levers 71
and disk 69, working in bearings in carriage-frame C, are duplicates of the
parts described as producing the escapement of wheel 81, and, whenever operated,.
as hereinafter described, produce a sliding motion of the plate 75.
Figs. 15 and 6.
See
The crank-pin 69¹, on the disk 69, is connected by universal joints to one end
of the lever 63, by a connecting-rod 68.
The extended ends of the key-levers 2 and 3, are provided with laterally-
projecting pins, which engage in the slots formed in the plates 66, the latter being
rigidly secured to the shaft 65, which (see Fig. 17) oscillates in bearings in
brackets g. To one end of the shaft 65, is fastened the lever 64, the oscillating
end of which is provided with a laterally-extending pin 67, which acts as fulcrum-
bearing for the lever 63. As already stated, one end of the lever 63 is connected
to the disk 69. Its other end is connected, by the link 62, to one arm of the bell-
crank lever 61, to the other arm of which is connected, by connecting-rod 60, to
the lever 59 and key-lever 53, the two latter being fastened to the same shaft 58
working in bearings in brackets k and I on platform D. Key-lever 53 is only
operated for changing from lower-case to capital letters, and is normally held up
by the spring 55. When it is depressed, it is held by a laterally-projecting tooth
catching in a notch formed in the spring-lever 160. The lever 53 is released by
depressing the lever 160.
The slots in the oscillating plate 66 are so formed that one part of the key-lever
movement produces the required movement in the levers 64 and 63, but leaves thein
stationary during the last portion of the downward movement of the key-lever,
and, while the key-lever is returning to its normal position. It also permits the
working edges of all the plates to move out of contact with the pins on the other
levers when any one of them is operated.
The oscillating shaft 65, with attached slotted plates 66, and levers 63 and 64,
are brought back to their normal position of rest (see Figs. 16, 17, and 18) by the
1

page_text: lever 105, which is fastened on the shaft 101, acting through the link 124, on the
lever 123, secured to the shaft 65, the part of the link 124 connecting it with
the lever 123 being slotted out so that only the last part of the movement of the
lever 105 is transferred to the lever 123, and, in order that the lever 105 can move
without affecting the lever 123, when the latter is in the position of rest.
The position of rest of the slotted oscillating plates 66 and of the key-levers 2,
is shown in Fig. 1. When any one of the key-levers 2 is depressed, the pin on the
back end thereof, which engages in the slot in the plate 66, slides along, the working
edge pushing the plate back during the first part of its movement; thereby
depressing the back end of the lever 63. The front end of the lever 63 being held
by the link 62 opposite the center of the shaft 65, it may be considered, during
this operation, as a rigid part of the shaft 65, and as merely an extension of the
lever 64. During the latter part of the movement of the pin on the key-lever 2 in
the slot in the plate 66, the latter, with all the parts connected therewith, will
remain stationary, while the escapement operation will take place by the disengage-
ment of the detent 78" and coincident engagement of the detent 76¹.
The motion of the end of the lever 63, will oscillate the shaft 70, and, by means
of the rod 72, will slide the plate 75 to a position so that, in falling, the pin 79 of
the pawl-arm 78 will strike the step made for the spacing of the character
represented by the key-lever depressed. The different motions for the spacing of
the different characters being obtained by setting the working edge of the slot in
the oscillating plate 66 at different angles to each other. The two extreme positions
of the sliding plate 75 are shown in Figs. 4 and 16, respectively.
The opening in the lower part of the slots in the oscillating plate 66 is formed
concentric with the center of the shaft 65, so that any plate may be operated by
its key-lever, independently of the other key-levers.
The keys 1, having no connection with the oscillating plates 66, or any moving
parts connected in any way with them, will, in being depressed, leave the sliding-
plate 75 in its normal position of rest, and only operate the escapement. The
edge of the plate 75, which, in this case, will be struck by pin 79 of the falling
pawl-arm 78, is at a height that the proper spacing will he produced for the greatest
number of letters occupying a uniform space in the line.
As capital letters, and similar characters, require one or several units more space
than lower-case letters or characters, steps are formed for this purpose on the
plate 75, which are brought into the proper position by shifting the plate 75
laterally. This is produced by depressing the key 53 until caught in under the
catch 160, thereby lifting, through the bell-crank lever 61 and the link 62, one end
of the lever 63, turning it on the pin 67, as a fulcrum, at the end of the lever 64,
and depressing the other end of the lever 63, sufficiently to bring the proper step
of the plate 75 in position through the connections already described.
The intermediate carriage E is made to receive a sliding motion on carriage-
frame C at right-angles to the sliding motion of the matrix-carriage F for the
production of inter-line spacing. (See Figs. 1, 4, 5, and 7.) To either side of the
carriage-frame C, is secured rack 112, into which gear pinions 111, both of which
are fastened to the shaft 110 (see Figs. 4 and 6). The shaft 110 turns in bearings
in the side walls of the intermediate carriage E. On the same shaft is also secured
the one-way ratchet-wheel 113, which is operated by pawl 115, held in contact by
the spring 116 (see Fig. 7) and carried by the lever 114. The lever 114, fulcrumed
on the end of the shaft 110, is provided with (at one end) the handle 118, the other
end being formed into two branches, each having a laterally-projecting pin 120.
To the pawl-arm 115, is secured the handle 117, to lift it out of engagement with
the ratchet-wheel 113. The plate 119 is provided with two slots sliding on
studs 122, and on its lower edge are formed two notches 121.
In operation, the lever 114 is moved in one direction, until one of the pins 120
strikes against the under edge of the sliding-plate 119, and then it is moved in the
opposite direction, until the other pin 120 strikes the under edge of 119. The
dimensions and position of the different parts being so adjusted that the
.

page_text: carriage E will be moved, by the pinions 111, co-acting with the racks 112, a
distance corresponding with the body of the font of dies being used. In shifting
the sliding-plate 119, so that pins 120 will enter the notches 121, a leaded inter-line
space will be obtained. In a similar manner, by providing additional notches and
shifting the plate 119 more, a double-headed inter-line space may be obtained.
Referring to Figs. 19, 23, and 24, as plan, side elevation, and cross-section,
respectively, and to details in Figs. 20, 21, 22, 25, and 26, the die-holder is composed
of the main-plate 14, to which is fastened, by the screws 28, the rectangular hub 18
having at its lower face a circular projecting part 27, fitting in the hole 27', and a
rectangular base, limited at both sides by projecting ribs, and fitting in the
rectangular hole 26, in plate 15. One end of the plate 14 is turned up to
receive the counterpoise 41, the other end having a rectangular enlargement.
Superposed on plate 14, is plate 15, sliding easily, by means of its hole 26, on base
of hub 18. To plate 15, are rigidly secured, by the screws 22, the shifting-
blocks 19 on its upper side and 20 on its lower side, the latter having a projecting
rectangular part fitting in the hole 21 in plate 14, and sliding therein.
To main-plate 14, is also rigidly secured, by a screw and a bolt fitting in the
hole 131, friction-roller 13 and block 40, having a rectangular projecting part on its
lower face fitting in the slot 25 in the plate 16, which slot also fits on the tongue 24
of the plate 15. Plate 16 has a segmental-shaped extension, to which, is secured,
by a number of screws, and interposed distance-pieces, the segment-shaped lower
plate 17. In the segment-shaped part of plate 16, and in plate 17, are holes for the
reception of the dies 32. The centers of these holes are disposed in circular arcs of
equal radii. The radius is of a length corresponding with the distance from the
center of the pivotal axis, about which the die-holder, as a whole, oscillates, to the
center of the stamping-punch, and the corresponding holes in the different series are
arranged on lines parallel to a line drawn through the center of the pivotal axis 29
and the center of the friction-roller 13. The holes are arranged in two equal series,
equally disposed on either side of an intervening large space, each series being
composed of three equal rows. The holes in the upper plate 16 are circular, while
those in the lower plate are square. The dies 32 have a square shank fitting neatly
and easily in the square holes in the plate 17. They have on the lower end a letter
or other character cut in cameo, the upper portion of the shank is formed into a
cylindrical stem slidingly fitted in the circular holes in the plate 16. The upper
end of this stem is rounded and formed with a diametrical perforation for the
reception of a pin, adapted to serve as an abutment for spring 32', holding the
square shoulder up against the under surface of the plate 16. The plates 16 and 17,
secured together, which we will designate by the term die-segment, form an
independent part, which may be duplicated for different styles of dies. This die-
segment is connected to the parts already described by the pushing-plate 16,
between the plate 14 and the shoulder on the block 40, into tongue 24 of the plate 15,
and, in a space left for the purpose, between the laterally-projecting parts of the
blocks 19 and 20, to which is rigidly secured, by the screws 23, so as to form, with
plate 15, a rigid part, sliding with ease longitudinally and in the same plane with
the plate 15 and the blocks 19 and 20.
The hub 18 and block 40 are connected, by the bracing rods 39, for the purpose
of stiffening the arrangement.
The hub 18 is fastened to the pivot-shaft 29, which oscillates in the pivot-
bearings and, both bearings being fastened to the frame-work B.
Partly to the reduced end portion 29', and partly to the body-part 29 of the
pivot-shaft, is fitted a sliding sleeve 33, freely sliding thereon longitudinally, but
prevented from turning on the shaft by a screw-point engaging in a groove 2911
(see Fig. 24). The lower part of the sleeve 33 is connected to the horizontal
arms of the two angle-levers 36 by the two connecting-rods 35. Both angle-
levers 36 are fastened to the same fulcrum-pin passing through a hole
near one of the corners of the rectangular hub 18. The vertical arms of the
angle-levers 36 are connected to the sliding block 19 by connecting-rod - 37.

page_text: '
Between the hub 18 and sliding block 19 is inserted a spring tending to hold them
apart, and taking up the play in the different connections. The upper reduced
part of the sleeve 33 is provided with a collar 34 in which it can freely and easily
rotate. To projecting parts of the collar 34, are connected the ends of the two
levers 42, by screws forming easy working joints. The two levers 42 are fastened
by a common hub to the fulcrun-shaft 43, turning in bearings t (Fig. 3), on top
frame B. To one end of the shaft 43, is fastened the lever 44 (see Fig. 1), the
: end of the front arm of which is connected with the lower part of the frame B, by
the spring 45, holding it normally down, and, thereby, the end of the back-arm is
held up. This end is connected, by the connecting-rod 47, to the end of the lever-
arm 48, the latter being fastened to the fulcrum-shaft 49, turning in bearings in the
. standards h, which are screwed fast to the bed-plate A. The end of the lever 50,
fastened on the same fulcrum-shaft, is connected, by the connecting-rod 51, to the
. end of the vertical arm of the angle-lever 52, which is fulcrumed in support k on
platform D. See Figs. 1 and 3. The horizontal arm of the lever 52 is provided,
on its two faces with projecting pins 56 and 57, both being in contact with the key-
levers 53 and 54, when up. The pins being at different distances from the fulcrum
of the angle-lever 52, are of different diameters. Key-lever 54 is, in all respects,
similar to the key-lever 53, already described, except that it is idle on its fulcrum-
pin, which is an extension of the shaft 58. Both key-levers 53 and 54 are provided
with laterally-projecting catch-plates, adapted to engage in the notch in spring-
lever 160. The catch-plate on the key-lever 54 is somewhat longer than the one on
the key-lever 53, so that, when the key-lever 53 is held by the spring-lever 160 in a
depressed position, and lever 34 is subsequently depressed, the former will be released.
The depression of the key-lever 53, as already described, will change the line-
spacing from that for the lower-case, or ordinary letters, to that for capitals.
The first row of dies in the die-holder, containing the lower-case characters, is in
a position, relatively, to be rotated under the stamping-punch, when the key-levers
are in their normal non-depressed position. When the key-lever 53 is depressed,
the second row of dies, containing the capitals and associated characters, is shifted
into the same position, and, at the same time, the spacing is altered to correspond
to capitals, etc. When key-lever 54 is depressed, the lever 53 thereby released,
restoring the spacing to that for lower-case characters, the third row of dies,
containing figures, fractions, and commercial and other signs, will be brought into
operative position when the die-holder is rotated under the stamping-punch. The
different parts operated for this purpose are so proportioned that these results are
obtained.
The normal position of rest of the die-holder is a central one, as illustrated in
Fig. 3. It is held in this position by the friction-roller being placed between the
two forked levers 10. Each of these two levers can be operated independently of
each other by a different series of key-levers, and each is provided with a slot 12,
exactly fitting over the friction-roller 13. The outside prong of each fork is long
enough to project beyond the friction-roller, while the inside prong is of such a
length that the roller in the oscillating of the die-holder can just move past it. The
forked levers 10 are fastened to the pivot-spindles 11, oscillating in bearings r,
the latter being fastened to the brackets q, secured to the projecting parts p of the
elevated framework B. Levers 10, moving in a horizontal plane, are connected to
levers 8, moving in a vertical plane, by the connecting-rods 9, with universal joints.
Each of the two levers 8 are fastened to the extreme ends of the fulcrum-shaft 7.
The two shafts are operatively independent of each other and lie in the same axis,
having bearings in the supports e and e', fastened to bed-plate A. (See Figs. 1,
13, and 17.)
To each fulcrum-shaft 7, are fastened a series of slotted lever-arms 5, or
graduated lengths (see Figs. 1, 3, 12, 13, and 14). The whole number of the arms
is equal to the number of dies in one row in the die-holder. In the slot in each
lever-arm 5, a pin 6 engages, which is fastened to the key-levers 1 and 2 at
graduated distances from the fulcrum-points of the key-levers. These slots in the

page_text: lever-arms 5 are so formed that all in one series can be lifted out from engagement
with the pins 6, by the depression of one of the key-levers or otherwise, without
affecting the position of any of the key-levers at rest, and they are further formed
so that, when any one of the key-levers is depressed to the proper degree, which is
the same for all of them, its pin 6 will engage and be rigidly held in the hook of
its slotted lever-arm 5. By this means, the momentum of the die-holder will be
prevented from carrying it beyond the proper point. The two extreme positions
of the slotted lever-arms 5 are shown in dotted line in Fig. 14, as consequent upon
the key-lever I being brought to the position shown in dotted lines. The graduated
dotted arcs represent the travel and position of the pins 6 on the key-levers 1 and 2
in each series.
In operating the machine, if a key of the left-hand series, as represented in
Figs. 12, 13, and 14, is depressed, all the lever-arms 5 will be lifted out of contact
with the pins 6 on the key-levers at rest; the lever-arın 8 will be oscillated and
communicate its motion through the connecting-rod 9 to the forked lever 10; the
slot 12 will engage with the friction-roller 13, and through it, the die-holder will
be rotated to the left, which will bring the required die of the right-hand series
into operative position under the stamping-punch, the parts being so proportioned
that this will take place. When a key on the right-hand side is depressed, the
operation will be exactly similar, except that the movement of the die-holder will
be in the opposite direction.
In the bearings n, n, and o, o, of the top frame-work B, are supported, in line
with each other, the two shafts 125 and 129. To one end of the shaft 125, is
secured a pulley 126, by means of which the shaft is constantly rotated, when the
machine is in use, by some motive power provided therefor. The end of the
shaft 129, near bearing n, is formed into a crank-disk 130, the pin of which is
connected by link 131, to the sliding-head 132, to the lower end of which, in a
central hole formed therefor, is fitted a punch 133, and retained by a set-screw.
The sliding-head 132 is guided in a guide-block w, which is fastened to the front
of the top framework B. The two shafts meet between the two central bearings o, o,
the space between the two bearings being occupied by a clutch-coupling composed
of the cheek 127, securely fastened to the shaft 125, and the sliding-check 134
sliding on feathers on the shaft 129. On the reduced part of this coupling-check 134,
is revolubly fitted the collar 135, to which is connected on its upper and under side
the two arms of the angle-lever 153. The lever 153 is fulcrumed on the screw
passing through a hub, connecting the two arms with the lever, which is screwed
into the top of the frame-work B. See Figs. 1, 3, and 34. When any of the keys,
except those used for spacing, only, are at rest, it is necessary that only one
revolution of the constantly-rotating shaft 125 should be transmitted, through the
coupling, to the shaft 129, independent of how long the said key is held in a
depressed position. It is further desirable that the force required to operate the
device provided for this purpose should not be appreciable on the key-levers, and
that the stamping operation should take place at the instant when the key is fully
depressed, and, therefore, when the proper type is exactly in its operative
position.
To the
These results are attained, alike for all keys, in the following manner.
shaft 125 (see Figs. 1, 3, and 27), is fastened the disk 128, which has secured to it
a laterally-projecting pin 147, in the path of which and eccentric to such path is
the properly curved surface of the projecting part 145 (see Figs. 27 and 28) of the
lever-arm 138 of the double-fulcrumed angle-lever 138-140, when the piece 145 is
in the position shown in Figs. 27 and 34, its normal position being that shown in
Fig. 1.
In this manner, the rotation of the pin 147 gives to the top of the lever 138
an oscillating movement outward from the center of the shaft 125. There is, imme-
diately under the projecting part. 145, and in the path of the pin 147, an oblique
projection 146 on the lever-arm 138, the latter turning with the fulcrum-shaft 136
in bearings s fastened to frame-work B, and transferring this motion to lever-arm 148,
which is also fastened to the fulcrum-shaft 136. The top part of the lever-arm 148

page_text: is connected to the angle-lever 153 by the link 154. See Figs. 3 and 34. This
constitutes the arrangement for coupling the constantly-rotating shaft 125 to
the punch-operating shaft 129. For the purpose of disengaging the coupling, after
one rotation of the shaft 129 has been effected, the shaft 129 has fastened to it a
disk 152 provided with a laterally-projecting pin 149, similar to the pin and disk 147
and 128. The top part of the lever 148 (see Figs. 29 and 34) is formed into a
curve 150, eccentric to the path of the pin 149, so that, in its revolution, the pin
will engage with the curved top of the lever and move that end of the lever-arm 148
inward toward the centre of the shaft 129-that is, to its normal position-until the
pin 129 is stopped by striking against the stop shoulder 150¹ on the lever 148.
To bring the lever-arm 148 from its normal oblique position (that shown in
Fig. 1), where its projecting parts 145 and 146 are out of reach of the revolving
pin 147, to its vertical position (that shown in Figs. 27 and 34), where the said
parts are in the path of the said pin, angle-lever 138-140, in addition to its rotary
movement about the axis of the shaft 136, is fulcrumed on the pin 139, passed, at
right-angles to the axis of the shaft 136, through the angular hub of the arm 137,
which is rigidly secured to the shaft 136. The arm 137 is placed in an oblique
position relative to the axis of the shaft 136, and serves as a guide and support for
the angle-lever 138-140, which has two cheeks, which fit over the arm 137. To
the horizontal ends of the angle-lever 138-140, at 140, are joined the two side-
arms of the lever 141 (see Figs. 27 and 34), the extremities 142 of which are
connected to two sliding strips 143. To the top end of the two strips 143 is
fastened, rigidly connecting the same, the catch 191, which, under certain conditions,
engages in hook of the pawl 144, which is joined to and between the two cheeks
of the tops of the lever-arm 138 by a pin, so as to turn easily, and so as to be held
or to fall back into a normal position, after having been lifted, by the action of
gravity or of a light spring. The strips 143 are guided in a block 193, fastened to
the oblique arm 137. They are rigidly connected, a little above the lower end, by a
cross-bridge, between which and the guide-block 193 is inserted a spring 192, tending
to force the strips and connected lever-arms downward. In the part bent at right-
angles to the side-arnis of the lever 141, and in a cross-bridge connecting the two
sides of the lever 140, are formed the bearings for the pin 141, to the outer end of
which is joined the connecting rod 155, thereby making a universal joint between
the lever 141 and the connecting-rod 155. This joint is held up by the spring 156,
acting between the shoulders formed at the hinge-point, and an abutment, secured
to the top frame-work B. The functions of the spring 156 consist principally in
counterbalancing. The lower end of the connecting-rod 155 is joined, by a slotted
joint 157, (see Fig. 1), to the end of the horizontal arm of the angle-lever 159
which turns on a fulcrum-pin secured to the standard i screwed to the bed-plate A.
The end of the vertical arm of the lever 158 is connected, by a connecting-rod 159
(see Fig. 1), to the lever-arm 104, which is rigidly secured on the shaft 101. When
any of the key-levers are depressed, thereby turning the shaft 101 and lever-arm 104,
the end of the horizontal arm of the lever 105 will be depressed, its pin moving idly
in the slot 157 until the last part of the movement, when the connecting-rod 155
will be drawn downward against the action of the spring 156. This, by turning
the lever 141 on the connecting-pins 142 as a fulcrum, will bring the lever-arm 138
from its normally oblique position (see Fig. 1) to the vertical position shown in
Figs. 27 and 34, when the pin 147, engaging with the eccentric curve of the
projection 145 (see Fig. 28), will throw the levers 138 and 148 outward sufficiently
to close, through the connections already described, the couplings, at the same time
moving the stop-shoulder 150 of the lever 148 sufficiently outward to bring the
groove 151 into the path of the pin 149. The groove 151 is circular, and, when in
this outwardly-tilted position, concentric with the path of the pin 149. The
shaft 129 is, in this manner, caused to make one revolution which will produce one
reciprocated movement of the sliding-head 132, and, with it, the stamping-punch 133,
thereby stamping or pressing the die already brought into the proper position, as
herein described, into the matrix-board supported on the matrix-carriage F.

page_text: While the pin 149 is moving through the groove 151 (see Fig. 29), the butt-end
of pin 147 (see Figs. 27 and 28) will slide along the oblique face of the projection 146
of the lever-arm 138, thereby throwing the lever-arm 138 back to its normal oblique
position. In this instance, and under the supposition that the key is not immediately
released from its depressed position, the center of the joint between the connecting-
rod 155 and the lever 141, being stationary, will act as a fulcrum for the latter and
the lever-end 140 of the lever 138-140 rising will cause lever-end 142 of the
lever 141 to rise, lifting the strips 143 against the action of the spring 192. This
will cause the catch 191 to engage with the hook of the pawl 144, remaining in this
position until the key is released. When the key is released, the spring 156 will
lift the rod 155 and the joint connecting it with the lever 141. In this instance,
the connecting joint between the lever 141 and the angle-lever 138-140 will
remain stationary, and, therefore, act as a fulcrum-bearing for the lever 141; the
extremity 142 of the lever 141 will move down by the joint action of the spring 156
and 192; the catch 191 will be withdrawn from the pawl 144; and the device, as a
whole, will be in a position (as shown in Fig. 1) suitable for the operation, as
described, to be repeated by the depression of another key or a second depression
of the same key.
To one side of the intermediate carriage E (see Figs. 31, 32, and 33), is
fastened the bell 161, while to the back side of the same carriage, is fastened the
plate 166. On a pin passing through projecting lugs of the plate 166, and
turning freely in them, are fastened the two lever-plates 163 and 164. The plate 164
has on its outward side a projecting nose catching on the end of one arm of the
lever-catch 165, fulcrumed to a hub on a projecting rib of the plate 166. The other
arm of the lever 165 is bent downward, and is provided, on its extreme end, with
an upwardly-projecting lug 165. The lever 165 is caused to catch to the nose of
the lever-plate 164 by a light spring (not shown). The lever 163 presses on the
spring-wire 162, which is fastened at one end to the projecting hub 166' of the
plate 166, and carries on its outer end the bell-tapper. To the back side of
the matrix-carriage F, and parallel with the direction of its motion, is fastened, by
lugs 169, rod 167, provided with two sliding buttons 168 and 168', which can be
fastened at any convenient point in the length of the rod 167 by set-screws. The
sliding-buttons 168 and 168' are formed on their lower side with projecting pins,
which act as stop-pins.
The operation of the signalling bell is as follows: When the matrix-carriage is
pushed by hand towards the left, and over the bell, for starting a line, the
button 168 having been secured at the proper point on the rod 167, the stop-pin
on the button 1681 will strike against the back part of the lever-plate 164, turning
it against the action of the spring-wire 162, until the catch of the lever 163
catches in the nose of the plate 164. By this operation, the lever 165 will press
the spring-wire 162, which carries on its end the bell-tapper, outward, to a position
ready to strike the bell. When, by the manipulation of the keys, the carriage F
is fed gradually forward in the opposite direction-toward the left-through the
action of the escapement already described, the stop-pin of the sliding button 168,
set and fastened at the proper place on the rod 167 for the desired ending of the
line, will come in contact with the lug 165' placed in an oblique position in relation
to the movement of the matrix-carriage, pushing the catch of the lever 165 out of
engagement with the nose of the lever-plate 164, and the hammer, being impelled
by the spring-wire 162, will strike the bell 161. The matrix-carriage can,
however, continue its movement until the stop-pin on the button 168 comes in
contact with the back-end of the lever-plate 164. The distance, in the movement
of the matrix-carriage F, between the warning of the bell and the end of the line,
is usually equivalent to the space necessary for from fifteen to twenty letters, and
is the line-margin within which justification of the line is to be made. By setting
and fastening the sliding buttons 168 and 168' at the proper points in the length of
the rod 167, lines can be made to start and to end at any desired point within the
margin of movement of the matrix-carriage F.

page_text: The locking-plate 109, formed with a rib 109', (see Figs. 1 and 35) is hung, by
its side-levers 10911, on screw-points under the platform D, so that the upper edge
of the rib 109' is just below the ends of all the key-levers 1, 2, 3, and 4. To one
of the side-levers, is fastened a stud, by means of which it is connected, by the
connecting-rod 107, to the lever 106 fastened the shaft 101 (see Figs. 1, 10,
and 11). To the connecting-rod 107, at a short distance from its end toward the
side-lever 109, is fastened the end of a spring 210, the other end of which
(see Fig. 35) is fastened to the stud on the side-lever 10911. A pin or a screw
projecting from the stud passes through a slot in the end of the connecting-
rod 107. To the side of the rod 107, is secured a pin or screw which acts as a
fulcrum for the thumb-lever 108. If this lever (108) is lifted, as shown in
Fig. 35, the edge of the rib 109¹ is drawn in under the ends of the key-levers,
preventing any of them from being depressed. If the thumb-lever 108
depressed, the edge of the rib 1091 is withdrawn from under the ends of the key-
levers, so that any of them may be depressed-the edge of the lever 108, which
engages with the pin projecting from the stud being so shaped, that, when the
lever 108 is depressed, this pin is moved in the slot toward that end of the
connecting-rod 107, part of the length of the slot. The top of all the ends of
the key-levers are bevelled off, so that, when any one of the key-levers is depressed,
the edge of the rib 109 can, without interfering with the end of the key-lever
being depressed, immediately move in under the ends of the other keys. The
rib 1091 is drawn in under the ends of the key levers, when any one of them is
depressed by the action of the key-lever on lever 102, shaft 101, lever-arm 106,
and connecting-rod 107 (see Figs. 1, 10, 11, and 35), any excess of movement of
the lever-arm 106 being compensated for by the spring 210, the slot in the end of
the rod 107 being formed long, for this purpose.
The machine may be provided with an index, composed (see Figs. 1 and 3) of an
ordinary scale similar to those used in type-writing machines, secured to the front
edge of the matrix-carriage F and an index-plate, with an index-line thereon,
fastened to an adjustable sliding-button 173, sliding on the rod 174, the latter being
fastened to the front side of intermediate carriage E, parallel with the movement of
the matrix-carriage F. When dies corresponding to fonts of small type are used, the
divisions on the scale become so small that an extra effort is required to read them.
As these readings have to be done as quickly as possible, in order to properly
adjust the line after the bell has been struck, it is found of an advantage to use an
arrangement whereby the divisions are relatively enlarged. This device,
illustrated in Figs. 36 and 37, consists in a main-plate 201, fastened to the
intermediate-carriage E, to which is joined, by screws 207 and 207' and by thumb-
screw 209, the plate 203. For the screw 207', is provided a slot 206 in the
plate 203, and, for thumb-screw 209, a slot is made in the main-plate 201, so that
the plate 203 can be turned around screw 207, as a fulcrum. To the plate 203 is
secured, by a number of distance-pieces and screws, the dial-plate 204. Between
the plates 203 and 204, are placed the gear-wheels 202, fastened to pivot-spindles,
the central one protruding through the dial-plate 204, and having an index-hand
secured thereto. One of the wheels 202 gears into the rack 208, fastened to the
front side of the matrix-carriage F.
When the thumb-screw 209 is loosened, the plate 203, with all its connected
parts, can be turned so that the gear-wheel 202 is disengaged from the rack 208.
The matrix-carriage F is then set in position for the end of the line; the hand 205
is turned to the zero-point of the divisions of the dial-plate 204-these divisions
corresponding to unit-spaces; plate 203 is turned back, so that the teeth of the
wheel 202 mesh with the teeth of the rack 208; and the matrix is pushed to the
right, ready to begin a line. The different desired keys are operated, causing
the matrix to move toward the right. When the warning-bell is struck, the word
then being stamped is finished, and then the number of divisions on the dial-
plate 204, from the position of the index-hand 205 is read off and compared with
the number of unit-spaces necessary for the succeeding words, spaces, and full

page_text: syllables which would fill, or nearly fill, the line. The number of unit-spaces
necessary to justify the line are then gradually added to the regular spaces between
the remaining words.
The manner of securing the matrix-board to the matrix-carriage is illustrated
in Figs. 31, 32, and 33. To the back side of the matrix-carriage F, is secured the
lipped-strip 170, under the lip of which the matrix-board can he slipped. To the
back part of the sides of the matrix-carriage F, are hinged the angular side
strips 171, one side of which overlaps the side edges of the matrix-board. The
angular strips 171 are held down on pins at their front ends, by notches formed in
the latches 172 (see Fig. 32), which are made so as to press the matrix-board
firmly down to the surface of the matrix-carriage F.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1. In a matrix-making machine, the combination with a fixed axis or hub, of a
sliding-plate, movable radially with relation to the hub, segmental die-plates
secured to the sliding-plate, angle-levers fulcrumed on the hub, and means for
actuating the angle-levers and the sliding-plate therefrom: substantially as and for
the purposes described.

hub substantially as and for the purposes described.
3. In a matrix machine, the combination with a suitable die-holder, of a hub
or axis, a main-plate secured to the said hub, a sliding-plate provided with shifting-

the purposes described.
5. In a matrix machine, the herein-described die-holder, consisting in two parallel
plates rigidly secured together at a proper distance apart, said plates being corre-
spondingly formed with several rows of guide-holes, for the reception of the dies,
