A Machine for Printing Large Letters or other Characters
Individually and Successively upon Paper or the like.
A communication from abroad by CHARLES AUGUSTUS MCCANN, of Hotel Oxford,
Huntington Avenue, Boston, Massachussetts, U.S.A., Merchant.
I, JORN CORRY FELL, of the Firm of Fell and James, of 1, Queen Victoria Street,
London, E.C., Chartered Patent Agents, do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
-
This invention relates to a machine for printing, individually and successively
upon paper, or other suitable material, large letters or other characters, such as
have been heretofore made by hand, either by the use of the brush or by rubber
stamps, and its principal object is to afford a means for printing more rapidly,
and with a more uniform and artistic appearance, bulletins, placards and like
productions to be posted in public places to be read at a distance, as, for example
those placed in front of newspaper offices, and those used by merchants to adver-
tise their commodities.
In the machine embodying this invention and accomplishing this result, the
paper or other material upon which the printing is effected is supported upon a
roller having a transverse step-by-step movement, as in the ordinary type-writer,
and each type is successively brought to a common point opposite this paper or
material, and the impression is then produced by the action of a suitable platen.
The type are made of rubber or other suitable material and are respectively
placed upon suitable flat bars or plates of any suitable material and capable of
individual and independent movement and these bars or plates are supported
side-by-side in parallel vertical planes in cases or carriages with the type all
faced in the same direction, each case or carriage containing a convenient number
of type-bars or plates, and these cases or carriages are capable of transverse move-
ment on the frame of the machine so as to enable any desired type-bar or plate
to be placed in position for engagement with a suitable device common to all the
type-bars or plates and acting to carry any desired type-bar or plate to the printing
point, preferably with an accelerating and then a decreasing velocity, and to pre-
sent the type upon the bar or plate to the paper or the material upon which the
impression is to be made, means being provided, whereby the bar or plate is turned
from a vertical plane to a plane at right angles to the first named plane.
The movement of the carrying device is effected by mechanism operated inde-
pendently of the movement of the cases or carriages and this mechanism also
acts to operate the printing platen.
After the impression the type-bar or plate automatically returns to its original
place in the case or carriage.
Means are also provided operated by the rotation of a shaft which by its partial
rotation in one direction effects the carrying of the type-plate to the printing
point and the printing and then returns to its original position, for adjusting the

page_text: case or carriage to such a position as to obtain an alignment of the desired type-
bar or plate with the carrier in order to insure the engagement of the latter with
the type-bar or plate and also to hold the carriage or plate in a fixed position until
the selected type-bar or plate returns to its original place in the case and these
means are operated by a single partial rotation of the shaft in one direction and
are released by the rotation of the shaft in the reverse direction.
In the embodiment of the invention shown in the drawings and hereinafter more
fully described the cases or carriages are moved by the hands of the operator to
the position to permit the engagement of the carrier with the desired type-bar
or plate and in this embodiment the movement of the mechanism for securing the
desired type-bar with the carrier, for holding the carriage, for carrying the type-
bar or plate to the printing point, for effecting the impression, and the release
of the case or carriage are successively effected by the single pressure of the foot
of the operator upon a suitable treadle, but I do not limit this invention to this
embodiment. The principle of this invention involves the production of the above
named movement by a single exercise of power and the independent movement by
any suitable means of the cases or carriages containing the type-bar or plate to a
position to permit the engagement with the carrier of any desired type-plate, and
this principle can be carried into effect in several ways, of which the device here-
inafter described and illustrated in the accompanying drawings, is one.
The actuation of the feeding mechanism is effected by the engagement of the
type-bar or plate, when the latter is brought to the printing point with suitable
mechanism and the feed movement thus produced is proportionate to the width of
the type on the bar or plate, thus ensuring spaces of uniform width between the
printed characters.
Two characters may be placed upon each type-plate arranged one above the other
en the line of the movement of the plate and means are provided for varying the
extent of movement of the type-bar or plate, in accordance with the position of
the character which it is desired to print, and means are also provided, whereby.
either of the devices for operating the feeding mechanism by the engagement of
the type bar or plate is placed in the path of the plate in accordance with the
character brought to the printing point and the other device is removed from said
path,

In these several figures similar letters refer to similar parts.
Referring to the drawings, A, is the frame supported upon suitable legs, a,
and to this frame are attached the several castings supporting the parts of the
machine.
The type-plates will first be described. The size of these plates should be
sufficient to carry large type, sometimes with an area of four square inches or
more, and the less the expenditure of time and power required to bring any one
of these type-plates to the printing point the greater will be the utility of the
machine. It is desirable that the same type-plate should be capable of carrying
two or more type, thus enabling the same device to be used for printing from
different characters or from different faces of the same character, as for example
block or script letters or upper and lower case, thus reducing the number of type-
plates required for printing a variety of letters or other characters. This result
can be accomplished by the use of oblong plates and in the embodiment of the
principle of the invention herein described type-plates of this form are used but
other forms of type-plates may be used in other embodiments.
These plates, B, may be made of any suitable material, but are preferably made of
a light material such as wood, and are of the same size and when the machine is
intended for printing newspaper bulletins a suitable size is four inches in width
and nine inches in length, but they may be larger or smaller, according
to the work which the machine is intended to perform, and the size of the machine.
Upon one face of the plate is secured a type of any suitable material. Rubber
type can be conveniently used with an ink adapted for use with such type.
In the lower end of the plate, is a recess, e7, for the reception of the catch, e',
on the spring, E, attached as hereinafter described which catch aids to secure the
type-plate to the carrier, and in the lower end of the plate are two recesses, B, B',
one on each side of the recess, c, and preferably near the edge of the plates for the
reception of one of the tines, e, e, of the fork by which the plate is seized and which
fork will hereafter be more fully described.
Each of these plates must be brought to the same point to be seized and carried
to the printing point and a convenient manner of accomplishing this result, con-
sists in the use of a series of cases or carriage for supporting the plates in con-
venient numbers. In the cases used with the machine described the plates are
supported at an angle in vertical parallel planes and each with its type-face turned
to the same direction.
The case or carriage, C, is shown in isometrical perspective in Fig. 8 and moves
transversely and in the same plane upon the frame of the machine and before the
operator who by hand moves the case or carriage to bring the type-plate from
which it is desired to print to a position to be seized by the fork. The bottom
of the case is provided with slots C, having enlargements, C, for the reception of
the tines, e, e, of the fork. It has sides, B², and each type-plate rests in a socket
formed respectively by the parallel bars, C, which are beveled, as shown, to
facilitate the entrance of the type-plate on its return movement.
A convenient manner for enabling the case or carriage to have a transverse
movement is by supporting it at the front part of its under side by wheels, 135,
attached at this part and moving on a suitable rail, A2, supported transversely upon
the machine and at the upper end by means of two guide wheels, c, c¹, on an arm, c²,
extending from the upper end of the underside of the case, each of which guides
moves on opposite sides of the inclineu bar a, supported by the standards, A³, and
parallel to the rail. A², and thus the case is prevented from upward movement.
The case or carriage may also be guided by a roller on an inclined arm, A6, on
the front part of the frame, A, and extending backward, one on each side of the

page_text: carrier-supports and below these supports, which roller bears on the upper side of
a Hange, a', on the lower front of the case or carriage below the slots C.
When the type-plate carrying the type from which it is desired to obtain an im-
pression, is brought to the position to be carried to the printing point it is desirable
in crder to enable the plate to be seized by the device which carries it to this point
that the case, C, should be firmly held in such a manner as to prevent its lateral
movement and that it should remain in this position until the type-plate is re-
turned to the case. It is also necessary- that the selected plate should register with
or align with the carrier in order that the catch and the tines of the fork on
the same should enter the recesses, e7, and B, B', respectively.
This result is accomplished by providing a bar, A, extending along the case on
its lower front edge and at right angles to the flange, a¹, and having on it a series
of V, shaped notches, C+, corresponding in number to the plates in the case and
each having its apex in a vertical plane passing through the center of the type-
plate above the notch, and also by providing a double beveled vertical wheel, D in a
vertical plane passing through the center of the edge of a type-plate when the
latter is in position to be carried to the printing point, said wheel being mounted
upon the arm, 11, of a shaft D2, pivoted to a support from the frame of the machine,
whereby the edge of the wheel can be brought against the bar, A7, and by enter-
ing one of the notches, C4, on the same will not only prevent the case from moving
laterally but will bring the plate above that notch to the position which will
enable it to be seized by the fork. The bar, a', prevents the upward movement of
the case during this operation.
Upon the edge of each plate may be placed a letter or character similiar to that
of the type on the face of the plate, and for the purpose of indicating the type on
the plate. The operator by moving the case transversely before him brings the
plate carrying the type from which it is desired to take an impression approxi-
mately opposite the fork and then by effecting an upward movement of the beveled
wheel he causes this wheel to engage with a notch, C, in the bar, A7, and thus
hold the case and bring the selected type-plate in position to be seized.
The device for seizing the type-plate consists of a fork with tines, e, e, and of
a width substantially equal to that of a type-plate and attached to a shaft, E,
rotating in suitable supports attached to a vertical plate, 12, fixed to the underside
of a sliding frame, F, and in a vertical plane.
A flat spring, E, is attached at one end to the shaft of the fork and the other
end of this spring is provided with a hook, &, which enters the recess, e, and
passes over a cross bar, e, in this recess and engages with the same thus holding
the type-plate.
The type-plate is brought to the printing point by the movement of the frame, F,
supported on each side respectively on one of two inclined parallel rods, A, extend-
ing from the front of the machine to a point above the roller carrying the paper
or other material on which the impression is made, and connecting at the upper
end and lower end by a cross bar, A, and the upward movement of this frame is
effected by winding a band, F', cord or chain, attached thereto upon a pulley, F,
to which the band or its equivalent F, is attached, and which pulley is fixed upon
a shaft F, supported above the rods, A", and near the upper ends of the same, upon
the parallel standards As, forming a part of the frame of the machine, a circular
opening being formed in each of these standards for the passage of the paper
roller frame and a part of each standard at this point is carried backwards and
forms the support for the rod of the printing platen.
The means for effecting the rotation of the pulley, F, will be hereinafter de-
scribed.
After the type-plate has been brought to the printing point and an impression
has been made and the power effecting the impression is released the frame, F
will return by the action of gravity to its original position at the lower end of the
parallel rods, A9, but means may be provided to facilitate its return.
When the frame, F, after the inpression, returns to its normal position the

page_text: type-plate carried thereby passes into its original position in the case or carriage
and is automatically disengaged from the fork.
The disengagement of the type-plate from the fork after the return of the carrier
to its normal position is effected by the engagement of the end of the arm, e, on
the inclined support, A6, or otherwise suitably supported, with the lower end of
the spring catch, E.
For the purpose of forming a compact group the type-plates are in vertical
planes. It is therefore necessary in order to present the type to the paper, or
other material receiving the impression, to give a quarter turn to the type plate as
it moves to the printing point. This result is effected by means of the guide
rod, A3, supported parallel to the rods, AP, on which the carrier moves but bent
at one point so that the direction of the rod is in two parallel lines, and a bell
crank lever, one arm, E, of which is connected by a curved link, E', to the fork
at a point eccentric to the axis of the fork, and the other arm, %, bears on the
rod A, and therefore the fork will turn as this arm moves in the rod, A13. This
movement is indicated by full and dotted lines in Fig. 7. A spiral spring, e', on
the arbor, e, of the bell-crank lever connects the arbor to the supports, e², and
maintains the arm, E, in contact with the rod, A.
The movement of the type-plate to the printing point with the consequent move-
ment of the paper carriage after each impression and the movement to effect an
impression may be effected by power exerted by the foot of the operator thus leav-
ing his hands free to move the carriage containing the type-plates.
The device which is used in the machine shown consists of a segmental rack, G,
on a quadrant, G', pivoted to the frame A and moving in a vertical plane at right
angles to the front bar of the machine. This segmental rack extends backwards
from the front of the machine and connected to the front of this rack and moving
with it on the same axis is a bar, G2, extending downward and which bar as is
shown may be cast in the same piece with the rack.
Attached to the bottom of the bar is a treadle, G3, for receiving the foot of the
operator, which treadle is preferably of considerable weight. The treadle is
swung backwards by the pressure of the foot of the operator thus partially rotating
the segmental rack and when the pressure of the foot is removed from the frame
the frame returns by its weight to its original position, and carries down the
segmental rack.
This device is a suitable means for applying foot power to operate the machine
but other means may be used and the segmental rack may be used when the power
used is other than the foot power.
The segmental rack, G, engages with a segmental or mutilated pinion, H, fixed
upon a shaft, H', suitably supported in the pendants, A19, extending downward
from the frame, A, and the partial rotation of the shaft in one direction effected
on the upward movement of the segmental rack effects the operation of the device
for aligning and holding the case.
The movement of the carrier to the printing point and the operation of the
platen are also effected by this partial rotation of the shaft, H', and the reverse
of this effects the release of the holding and aligning device. In the embodiment
of the invention shown and described a spring U2, attached at one end to the frame
and at the other end attached by a chain or cord, U¹, to a pulley, U, on the
shaft, H, effects the reverse rotation of the shaft, H', but its reverse motion may
be effected in any suitable manner.
It is desirable that the case or carriage containing the type-plates should be
held in position and the selected type-plate should be seized by the fork before the
movement of the type-plate to the printing point commences and that this move-
ment should commence slowly, proceed with an accelerated motion and end slowly,
thus avoiding a violent blow of the type-plate upon the device with which it comes
into contact on the completion of its movement and also that the impression should
be effected with force after the type-plate has been brought to the printing point.
In order to effect this desired movement of the carrier the principle that a body

page_text: given a reciprocating motion by being connected to a revolving arm will move
with a velocity proportionate to the sine of the angle passed over by the arm is
availed of, and therefore, in carrying this invention into effect a radial arm is
attached to the rotatable shaft and the carrier is connected to this arm by
suitable mechanism. Various forms of mechanism can be used for this purpose,
as for example, the arm may be connected by a band, chain, or cord to a pulley and
upon the axle of this pulley there may be another pulley upon which is wound a
band, chain, or cord attached to the carrier. The means shown in Figs. 1 and 2
of the accompanying drawing and hereinafter described is reliable and suitable
for the desired purpose but in carrying this invention into effect it is not limited to
any particular means for this purpose.
Upon the shaft, H', is an arm, H2, and this arm engages by means of a roller, h,
on the same with a curved cam slot or groove, h, in a lever, H, pivoted at its
front end to a lug, A, on the front part of the frame, A. To the rear end of
the lever, H, is pivoted a substantially vertical bar, H, having rack teeth on its
upper end which teeth engage with a pinion, F, on the shaft, r, of the pulley
T'he
upon which is wound the band, F', or its equivalent connected to the carrier.
extent of rotation given to the shaft, H, by the segmental or mutilated pinion is
such and the arm H³, is so placed on the shaft that the distance passed over by
the end of the arm on its movement will be sufficient to give an accelerated and
then a diminished velocity to the carrier. The teeth of the rack are kept against
the pinion by a suitably supported roller 68.
For the purpose of varying the extent of movement of the carrier accordingly
as it may be desired to bring to the printing point the upper or the lower type on
the type-plate the rod, H+, is pivoted on a block, k, which slides on a guide rod, k,
parallel with the upper edge of the lever H³, and attaches thereto and this block
is moved on the guide rod k', against an adjustable stop ³, by means of the
horizontal arm H, extending to the front of the machine. When the lower end
of the bar, H', is moved on the guide-rod towards the stop, k, the radial arm on
its movement will carry the cam lever further downward than when the lower end
of the bar, H, is near the front end of the guide-rod in the position shown in
Fig. 2 and consequently an increased movement of rotation will be
given to the shaft F, and the carrier will
move to bring the
lower type on the type-plate to the printing point. The horizontal arm, H5, is held
in position when moved by the engagement in a recess, k, on the horizontal rod
with a block, k, on the under side of a spring plate,, attached to the lever, H³,
which lever is curved upward at its central part in order to reach the horizontal
rod. The operator of the machine is thus able at will to vary the movement of
the type plate to bring either of the type on the type plate to
the printing point and thus with the type-plate shown is enabled
to print a letter from either the upper or lower case at will without changing the
series of type-plates. On the inside of the curved standard As, is a support, A,
on which is an inking roller, L, and on the movement of the type-plate to the
printing point the type passes above and in contact therewith and in order to ensure
pressure of the inking roller against the type it may be supported as shown upon
à frame,, hinged at one side to the support, A6, at the other end supported upon
an adjusting screw 1.
Suitable rollers, M, each respectively mounted on the inside of one of the
standards, A8, bear upon the type-plate as it passes to the printing point and hold it
against projecting spring plates, m, each attached respectively to the under side of
a block, M, extending longitudinally on the inside of each standard, A8,
The mechanism for moving the beveled wheel, D, which when thrown up effects
the alignment of the carrier with any desired type-plate and holds the case con-
taining a series of type-plates is designed to give a sudden movement of the wheel
and is shown in detail in Fig. 14. It consists of a segmental cam, D6, fixed on
the shaft, H¹, and of a roller D on the extremity of the lever, D, pivoted on the
shaft, d', supported under the frame A, said lever bein connected at its other

page_text: end to the link, D³, connected to the arm d. On the cam, D, is a depression, ³,
in which the roller, 15, normally rests but when the shaft, H', commences to rotate
the roller passes out of the depression on to the cam surface thus throwing up the
beveled wheel, D), into engagement with one of the notches, C', on the bar, A7, on
the case and holding it there until the shaft has completed its reverse rotation.
In the herein described embodiment of the principle of this invention the im-
pression of the type is effected by the action of a suitable platen which presses
against the type on the type-plate, when this type is brought opposite the platen,
the paper or other material on which the impression is made. This platen, I, is
shown in detail view in Fig. 18. It is attached to a rod, I', reciprocating in sup-
ports on the rear of the standards, A8, below the plane of the movement of the
type-plate to the printing point and at right angles to this plane. The upward
movement of the rod, I', to bring the platen, I, against the paper or other material
to be printed is effected by the engagement with an adjustable block, i, on the
rod, I, of one arm, I, of a bell crank lever on a shaft, supported between the
sides of the frame, A8.
The other arm, 13, of the bell crank lever is connected by a rod, I, with an
arm, I on a collar on the shaft, H¹ An arm, 16, on the shaft strikes against the
underside of the arm, I5, when on the rotation of the shaft H', the type-plate has
been brought to the printing point. The platen will return by gravity but a
spring, may be used to aid the return.
The device for supporting the paper or other material for receiving the im-
pression is similar to that used in the ordinary type-writing machine. It consists
of a cylindrical frame, N, mounted on parallel rods to move through circular open-
ings in the standards, A8, and below the platen by means of rollers, n³, on suitable
ways, A7 on the standards A8 and of a roller N¹ mounted on said frame and
parallel with the axis thereof which roller supports the paper or other material
receiving the impression. The paper or other material receiving the impression
is contained within the frame and passes over the front of the roller N¹ and over
the platen and as it is printed upon is fed over the curved support N2 preferably
elastic, attached to the supports A19 on the frame. Rollers nº or their equivalents
on the extremities of bars, 10, attached at intervals to the frame bear upon the
paper on the roller as shown in Figs. 1 & 2 and the paper may be maintained
against the paper roller by rollers n n¹ on a frame, n², pivoted on one of the parallel
rods on which the frame moves as shown in Figs. 3 & 4.
On the front of the cylindrical frame and parallel to the roller is a rack-rod, N
and loose on the rod is the engaging device by means of which the paper-roller is
moved transversely to feed the paper after each impression and supported between
the supports, A8, is a rod, N³, which is embraced by the engaging device and
serves as a guide for it. The form of engaging device used in this embodiment of
the invention is shown in detail in Fig. 16. Pivoted upon the block n, is a pawl n
engaging with the teeth of the rod, N+, and so placed that when the pawl engages
with a tooth and the block, n, moves, the pawl will cause the rod, N4, and the frame
carrying the paper-roller to move in the direction to furnish a fresh surface for
an impression. Instead of an engaging device operating by means of a pawl
acting on a rack bar, any other suitable engaging device may be used as for ex-
ample, some form of friction clutch.
The movement of the engaging device to effect the feed of the paper is accom-
plished by means now to be described. Moving in supports o, and o¹, the latter
attached to the bar, A2, connecting the rods, A2, and the former to a cross piece
connecting the standards, A8, is a rod, 06, upon which are secured two arms, 05
and 0 each extending in opposite directions and at a distance apart equal to the
listance between the type on the type-plate. 03 is a rod parallel to the rods. Aº,
nd moving in the bar, A2, and fixed on this rod is an arm, 04, having a fork at
ts end which embraces the rod 06, above the arm 05, and to this rod is attached a
pring. 08, the other end of which is attached to the frame and which spring is
xtended by the upward movement of the rod, 03, caused by the engagement of

page_text: the arm, 05, and which upward movement is caused by the engagement of a
projection upon the upper edge of the type-plate when the latter has been moved
to bring the upper case type on the same to the printing point. Inasmuch as this
projection is of a length proportionate to the width of the corresponding type on
the type-plate the extent of movement of the arms, 05 and 07 will correspond
to the width of the type.
At its lower end the rod, 03, is attached to an arm, 03; moving in a slot in
the arm, O of a bell crank lever pivoted on the cross piece, A between the
standards, A8, and the other arm 0, of the bell crank lever is pivoted on the
block n, on the rod, N. When the rod, 03, is moved upward by the action of
the projection on the type-plate on the arm, 05, or, 07, as the case may be, the arm 0
of the bell crank lever carries the block, n, towards the right but when the type-
plate leaves the arm 05 or 07, on its return movement the spring 08, acts to move
the arm 0, to the left and by the engagement of the pawl n', with the teeth of
the rack rod, N, to move the rod and consequently the paper roller frame for a
distance corresponding to the distance of the movement of the rod, 06. The lower
projecting arm 07, forms one arm of a forked arm fixed to the sliding rod, 0,
and this arm, 07, is shown in Fig. 10 in position to be engaged by the projection. bl,
on the type-plate corresponding to the lower case letter on the plate and when the
type-plate is to be moved to its greatest extent to bring the upper case type to
the printing point and the upper edge of the type-plate is made to engage with
the arm, as shown in Figs. and 4, the arm 07, is swung backward out of the
way of the projection 6. This action is effected by the movement of a projection
on an arm, R, on the shaft, R', rotating in suitable supports attached to the sides
of the right hand standard A8, and this arm, R, has a fork which engages with a
rod extending downward from the other branch of the forked arm and thus moves
the arm 07, out of the path of the plate.
The rotation of the shaft, R', to remove the arm, 07, from the path of the type-
plate and the consequent engagement on the upward movement of the type-plate
with the projection on the type-plate corresponding to the lower case letter is
effected by the engagement with a bent arm, R2 attached to a collar on the lower
support a, by the rack rod, H, when it is swung back by the horizontal arm, H³,
for the purpose of increasing the movement of this rod by the radial arm H².
The collar carries a pin, a", and when the collar is rotated by the movement of the
bent arm 12, the pin 17, strikes an arm on the rod, R, and at right angles to
the pin and thus effects the rotation of the rod. R¹, and the consequent movement
of the forked arm, R, and arm, 07 as shown in Fig. 10.
The projections b, b, on the upper edge of the type-plate are of different lengths
or heights according to the width of the corresponding type on the plate and may
be formed by inserting pins in the upper edge of the type-plate or by cutting
away the upper part of the same as shown in Fig. 5. For the purpose of pre-
venting the type-plate when its upward movement is limited to bring the upper
character on the same,-in the type-plate shown, the lower case letter,-to the
printing point from striking the arm, F; then in position to be engaged with
the projection upon the upper edge of the type-plate, with such force that this
arm will be carried so far that the extent of movement given to the engaging
device will be greater than is desirable, a rod, 10, is provided moving in the line
of movement of the type-plate on an arm, o¹¹, attached to the rod, R¹, and suit-
ably bent to avoid contact with the guide rod, A, and this rod oo, is provided
with enlargements at each end which retain it on the supporting arm. On the
reciprocating movement of the rod, and when the rod, R', is turned to bring the
arm, 07 in to position to be engaged by projection on the type-plate when the
letter moves to the printing point the end of the rod, oo is struck by a rubber
block 0, on the upper part of the carrier before the projection on the type-plate
strikes the arm, O, and the force of the impact of the projection is lessened. When
the bar. H has turned the arm, 07 out of the path of the type-plate as before
explained the rod o is turned out of the path of the carrier.

page_text: The pawl, of the engaging device moves in a slot in the block, n6, and is on
one arm of a bent lever, 71, and a cord or chain, f2 passing over a suitable idler
on the frame A8, connects this bell crank lever to an arm, f, on the rock shaft, i,
which rock shaft is moved by the large rod, I, connected to the arm, 15, loose on
the shaft, H. When this arm I, is moved upwardly by the action on it of the
fixed arm, I, on the partial rotation of the shaft, H', on the first movement of the
rotation of the same and the impression is made by the engagement of the arm. I,
with the rod, I', of the printing platen, the arm, f, is thrown up thus tightening
the chain, and disengaging the pawl, 7 from the rack bar, N. A spring, f
may connect the chain, f to the arm, f. On the disengagement of the pawl, n7,
the block, is free to move on the rack bar N4, by the action of the lever, O,
actuated by the movement of the sliding rod, 0, and this movement is against
the tension of the spring, 08, but when the type-plate leaves either of the armis, 05,
or 07, on the rod 06, the chain f¹ has been loosened by the return movement of
the arm, f, and the pawl, has engaged the rack bar. The retraction of the
spring 08, is thus enabled to effect the movement of the rack bar N4, and the
movement given to the rack bar will be for a distance equal to the movement
given to the rod, 0 and its connected rod, 03, by the engagement of either of the
projections, b, b, on the type-plate with that one of the arms on the rod, 06, which
is in the path of either of these projections and the height of
letter to which
the projection is proportionate to the width of the
it corresponds spaces of uniform width will be formed between
Trinted characters. Upon the upper side of the segment G¹, is a pin to which
is attached a spring, T, shown in Fig. 3 which spring is connected by a cord or
chain, T pasing over suitable idlers on the frame to the lever, and this spring
is extended on the downward movement of the segmental rack, G, when the type-
plate commences to return and therefore acts in aiding to effect the feed movement
of the engaging device.

To effect the spacing between consecutive words the following means are
employed. Against the end of the arm of the bell-crank lever the end of the
upper arm of the lever T, Figure 3, is adapted to bear. Said lever T is pivotted on
one of the standards AS and the end of its lower arm is connected by means of
the connecting rod T with the hand-lever T2 pivotted on the frame A at the front
of the machine. On pulling the hand-lever T2 forward the upper arm of the
lever Trises and causes the arm of the bell-crank lever to carry the block n
towards the right, so that on releasing the hand-lever T2 the reaction of the
spring 08 effects the feed of the paper as hereinbefore described and effects the
required spacing.
The paper roller carriage is pulled back to the starting point by means of a
chain or cord, P2, which passes over suitable idlers on the frame of the rack and
is moved on the wheel, P3, on the front part of the machine:
When it is desired to carry the roller back the pawl, n is disengaged from the
rack bar, N+, by the depression of the outer end of the lever, p', on which the pawl
is pivoted and this depression is effected by means of the swinging rod, !', sup-
ported on the frame of the paper roller and connected by an arm, P', with the
cord. P².
The paper-roller is rotated to form the spaces between the lines by means of the
engagement with a toothed wheel S, on the shaft of the roller with pins, s, s, on a
beveled gear wheels which is rotated by a beveled pinion, S2, on the shaft, $3
extending to the front part of the machine and suitably supported on the frame
or any other suitable means may be used for effecting this result.
For the purpose of obtaining a sufficient number of type-plates for printing
inasmuch as the number of type-plates contained in a single case or carriage is
limited by the size of the case, supplementary cases or carriages shown in Fig. 5
are provided supported on frames, A2, moving by means of wheels, B7, on trans-
verse rails, A on the frame A, on one or both sides of the inclined supports on
which the carrier moves.

page_text: Each case in the frame, A moves laterally upon rails, A2 in the frame and this
rail registers with the rail, A2 as the frame A4, is moved to bring either of the
cases to move on the rail A2. A convenient means of ensuring registering or
alignment of either of the rails A2, with the rail A2, is by means of the lever, V,
Fig. attached to a collar on a rod, ¹, extending from the frame
which collar is connected by a spring, e, with the support on which it rotates; upon
the upper surface of the lever, V, is a recess, in which the ends of the rods, A²
and A rest, and by which the necessary alignment of the two rods to enable the
case to slide from one to the other is secured.
The operation of the machine is as follows.
The operator moves the case containing the type-plate from which it is desired
to print to a position to enable the selected type-plate to be engaged by the carrier
when the frame is aligned with the carrier to bring the tines of the fork of the
carrier opposite the recesses in the type-plate. The treadle is then depressed thus
partially rotating the shaft, H', in one direction and on the commencement of this
rotation the beveled wheel is thrown up and its edge enters that one of the notches
on the underside of the case and which corresponds to the selected type-plate and
the alignment of the fork with the type-plate is effected and the case held from
lateral movement. The type-plate is thus in position to be seized by the carrier
and the movement of the radial arm caused by the mechanism operated on the
further rotation of the shaft then effects the movement of the carrier to bring the
type-plate to the printing point, the said type-plate during this movement turning
from a vertical position to a position to present the type to the impression surface.
The arm fixed on the shaft then on the further rotation of the shaft, strikes the
other side of the arm loose on the shaft and effects the movement of the printing
platen to cause an impression. The movement of the printing platen disengages
the pawl of the engaging device from the rack bar on the paper roller supporting
frame and the engaging device is moved by the engagement of the type-plate with
the devices moving the engaging device, the springs connected to this mechanism
are extended and on the engagement of the pawl of the engaging device with the
rack-bar by the return of the platen the paper-roller frame by the retraction of the
springs is fed forward for a distance proportionate to the width of the letter printed.
The type-plate then returns to its place in the case and by the operation of the
shaft on its reverse rotation the case is released.
These successive operations are performed with great rapidity and a number of
words can be printed per minute.
Inasmuch as this invention is the first in which the printing of characters of
large size has been effected by independently and individually movable type-bars
or plates each successively brought to the printing point the invention is not
limited to the particular means described for carrying it into effect but the inven-
tion can be embodied in other forms of mechanism without departing from the
spirit of the invention.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I claim

on the arm and means for removing said rod from the path of the carrier by the
means which removes the arm, 07, from the path of the type-plate, substantially
as described.
43. In a printing machine of the class described, the combination of a series of
rectangular type-plates arranged in parallel vertical planes, a carrier for conveying
any one of the type-plates to the printing point, an inclined case for containing these
type-plates and having a lateral movement to bring any desired type-plate into
position to be engaged with the carrier and having its bottom in a plane parallel with
the plane of movement of the type-plates, parallel bars on the bottom of the case
and forming a series of sockets each for the reception of a type-plate, means for
preventing the upward movement of the case and means on the front of the case
for permitting the entrance of the device for effecting the engagement of the carrier
with a type-plate substantially as described.
44. The combination with the case, C, the standard, A³, the inclined bar,
supported by the same, the transverse rail, A3, on the front of the frame, A, the
rollers, B, 136, attached to the case and moving on the rail, A², the projection,
on the underside of the case and the rollers, c, c' on the projection and bearing on
each side of the bar, a', the flange a¹ on the front of the case and supports, A, in

page_text: front of the case each carrying a roller bearing on the flange, a¹, substantially as
described.
45. In a printing machine of the class described, the combination of a frame,
inclined type-plate cases having a lateral movement therein, parallel rails on the
frame of the machine and extending from back to front, wheels on the frame for
the type-plate cases and moving on these rails, a transverse rail on the front part
of the frame of the machine, parallel rails on the frame supporting the cases at
right angles to the rails on the frame of the machine and on which first named
rails the cases move and each of said rails when the frame supporting the cases is
moved from back to front registering with the rail on the front part of the frame
of the machine, thus enabling any of the cases to be moved to bring any type-
plates contained therein to a position to engage with a carrier for conveying the
type-plate to the printing point and means on the frame supporting the cases and
engaging with the lower part of the front of the same, substantially as described.
46. The combination with the moving frame, A24, for the type-plate cases, the
parallel rails, A25, on the said frame, the rail, A2, on the front of the machine, and
the pivoted spring levers on the side of the frame engaging with the under side of
each rail, A25, and with the under side of rail, A2, when either rail, A25, registers
with the rail, A³.
