Improvements in Presses for Embossed Printing.
I, JOSEPH YARDLEY JOHNSTON, Manufacturer of Stationery, of 33 Barkley
Street, New York City, in the County and State of New York, U.S.A. do hereby
leclare 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 improvements in the press for embossed printing, for
which I obtained Letters Patent dated September 5th 1893, No. 16,704 and consists
in a novel arrangement and construction of the mechanism operating the funda-
nental parts of the press, as hereinafter fully described, with the resuit of increasing
the speed of the press, diminishing the expense of operating it, and greatly
ugmenting the perfection of its work.

Similar letters and numerals designate the corresponding parts in all the
figures.
A is the frame of the press, having the base a, and being provided with the
arms 1, 2, and 3, supporting the driving mechanism. The press frame is mounted
upon a suitable stand B, having the cross-tie C. provided with the flange b, which
supports the paper-feeding and wiping device as hereinafter explained.
Dis the main shaft, located centrally near the top of the press, and carrying the
driving pulley E, loosely mounted thereon, but without lateral play. The move-
ment of the main shaft is controlled by handle 9, in connection with an incline not
shown, spring 10, and rod 8, having the forked arın 7, whereby the sliding clutch 6
is noved backward and forward into and out of engagement with the fixed clutch 5,
attached to the driving pulley.
G is the revolving die-carrying arm, firmly attached at one end to vertical
shaft F, and having at the other end die box 26, in which moves up and down die
plunger 25, carrying at its lower end die block 28, which is supported by spring 27.
Motion is transferred from shaft D to shaft F by pinion S, cog-wheel T, supported
by stud 16 and carrying mutilated bevel gear t, and bevel pinion Q. The teeth of
mutilated bevel gear cause one complete revolution of pinion Q, and by con-
sequence of revolving arm G, at each revolution of cog-wheel T, and are so disposed
that the blank portion 14 of the gear is presented to pinion Q whilst the operations
of locking and unlocking the revolving arm and striking the impression blow are
being performed.
Revolving arm G is locked and unlocked by locking-pin H, which moves
vertically in sleeve 17, attached to arm 2, being pressed downward by spring 18
and elevated by lever 1. Lever 1 is pivotally attached to bush 19, its forward end
resting in slot 20 of the locking-pin, and its rear end, carrying roller 15, resting
against cam K, attached to the front face of cog-wheel T.
Fig. X shows the relation of blank space 14 to cam K, and the projections 21
and 24 of cam K, by which respectively the locking pin is raised just before the
revolving arm brings the die plunger under the screw plunger, and just after the
impression blow has been struck. The lower end of the locking-pin is furnished
with fingers 22 and 23, the former impinging upon rib y suitably located on the
top of the revolving arm and by friction checking it, and the latter finally locking
it without jar as the spring forces the pin down over rib g, which adapted to fit
snugly in the space between the two fingers.
Die block 28 has on its under side a transverse dovetailed groove 30, and sliding
in it the correspondingly dovetailed tenons 30 of the two jaws 29 and 291. These
tenons form suitably Leaded nuts for the right-and-left-hand screw 31, supported

page_text: by plates 32 and 321, and serving to move the jaws (which hold die d) conjointly in
and out from a common center. For centering the die longitudinally is provided
the gauge 33, having the channel 37 to receive the point of set-screw 36, and which
slides in a suitable groove 31', located centrally in the bottom of the die block, on
one side of and at right angles to groove 30. The bottom 34 of the gauge is flush
with the bottom of the die block, but the projecting shoulder 35 catches the die
and thus accurately centers it longitudinally. Un base plate a of the press and
directly beneath screw plunger 38, rests the moveable counter plate c, held in place
by dowels or otherwise, upon which the counter or counter die is built up. This
moveable counter plate, in conjunction with the sliding jaws and gauge, admits of
the removal of the counter and die and their accurate replacement at any time.
Screw plunger 38 moves up and down, for about one-third of a revolution, in a
suitable nut located centrally in the front part of the press frame, its upper end
passing through the casing L, and carrying weighted cross-bar R. In the bottom
of the casing lies coil spring 40, its iuner end being secured to sleeve 41, which is
keyed to the plunger, and its outer end resting loosely against lug 42 or ring 43
lying moveably in the bottom of the casing. The exterior face of ring 43 at the
front of the press is provided with teeth, into which fits, through an opening in the
casing, the thread of worm W, moving in bearings 44 and operated by the square
head 45. At the upper part of sleeve 41, and carried by it, is arm 57; and
pivotally attached to the outer end of arm 57 is link 56, having (at its head)
shoulders 58 and 59 and rolier 55.
Superimposed on sleeve 41, and surrounding screw plunger 38, is hub 47 of
cog-wheel 51, located in the upper part of the casing, and revolved by pinion 50),
carried at the top of shaft 48, which is supported in bush 49, and driven by bevel
wheel X on its lower end and bevel wheel V on main shaft D. Cog-wheel 51
carries a tripping bolt 62, adjustably located in slot 63, and the depending sleeve 52.
Surrounding sleeve 52, and at the same height above the bottom of the casing as
link 56, is ring 53, held in place by three pins passing through slots 64 in the
sleeve, the third pin being rigidly attached to one end of spring 65, within the
sleeve, the other end of spring 65 being rigidly attached to the sleeve.
the exterior surface of ring 53 in the rib or shoe 54 and on the interior surface of
the casing, at about the same height from the bottom, is the fixed shoe 60.
Directly in front of pinion 50, and in the track of link 56, is the finger or cam 61,
supported by standard 46, rising from the floor of the casing.
On
In operation, the forward end of the elastic shoe 54, carried by sleeve 52 of
revolving cog-wheel 51, catches shoulder 58 of link 56 and thereby carries the
link with it, thus turning screw plunger 38 and winding up coil spring 40, until in
its progress link 56 is thrown off shoe 54 by finger 61, when its shoulder 59 catches
upon the forward end of shoe 60, and is there held until tripping bolt 62 comes
along and disengages it; and then coil spring 40 retracts the screw plunger, and
the impression blow is struck. At the instant of the plunger's rebound, the
forward end of shoe 54 again catches shoulder 58, its elasticity preventing jar, and
the operation as just described is repeated. The tension of the coil spring, and by
consequence the force of the impression blow, are regulated by worm W and toothed
ring 43.
N is the die inker, located in the path of the revolving die, its reservoir or
casing being supported by shank 102, resting on coil spring 104, whose height is
adjusted by thumb-nut 105, in sleeve 103, sustained by bracket 0, suitably attached
to the base of the press; whereby the inker is provided with a swivel motion,
which adapts it to any size of die that may be used, and which is regulated by
set-screws 107, passing through lug 108, and pressing against bar 106, attached to
shank 102. Collecting roller 109 is carried ou a short shaft, which also carries
ink agitator 114, one end of the shaft being supported by pointed screw 115, and
the other end fitting into a slot in rotating plug 116; whereby the removal and
replacement of the roller is facilitated. The journals of the shafts of the evener 110
and the roller 111 rest. in holes located eccentrically in stationary plugs 113;

page_text: whereby their pressure on the collecting roller is regulated and their removal and
replacement facilitated. The agitator and rollers are kept in continuous motion in
the following manner; sprocket wheel 4 is secured to driving pulley E, and
conveys motion to sprocket wheel 122 on one end of a shaft carried by sleeve 129,
which is supported at its center by shank 130, resting on coil spring 131, in
standard l', attached to the base of the press frame: at the other end of the shaft
turning in sleeve 129 is sprocket wheel 127, which transfers the motion by chain 126
to sprocket wheel 125, fastened to one end of shaft 128, turning in sleeve 123
attached to the casing of the inker; at the other end of shaft 128 is bevel
pinion 124 which gears with bevel pinion 117, attached, to the outer end of
plug 116, with the inner end of which the shaft carrying the collecting roller is
connected, as above stated: bevel pinion 117 carries a pin 121, working in slotted
lever 120, which is connected by shaft 132 with forked lever 119, between whose
prongs works the pin of crank arm 118, attached to the ink agitator. Near each
end of the shaft of the inking roller are the disks 112 and 1121 upon which the
outer ends or cams 39 and 391 of jaws 29 and 291 impinge as the die carrying arm
revolves, depressing the inker just before the inking roller touches and leaves the
die, whereby the edges of the die are kept clean, and the inking roller is forcibly
thrown against the face of the die by coil 104. M is the combined wiper and
paper-feeding device, located in the path of the revolving die m being the top
plate or wiping surface attached by screw-bolt 86 to plate 68, which is also the
top cross-piece, and 67 the bottom cross-piece, of the frame 66, which carries the
paper-feeding apparatus and wiper, and 70 being the lever which supports it all by
means of the ball-shaped pivot 69, downwardly projecting from the center of cross-

between, and is attached by pivot 71 to, the forked ends 72 of an arm projecting
from the base of the press, and rests upon set-screw 73 as a fulcrum, by which
set-screw also the height of the lever, and by consequence of the wiper plate, is
adjusted. Tappet-cam 74, on the upper face of bevel cam 75, which is carried by
vertical shaft F', acting on roller 76, at the inner end of lever 70, throws the wiping
surface against the die. Simultaneously hook 77, which is pivotally attached to
the inner end of lever 70, actuated by spring 79, catches upon plate 78, attached to
arm 3, and firmly holds the wiper whilst the die is passing over it. The length of
to shaft. F, which
the wipe is regulated by tappet 80, adjustably attached
disengages hook 77 from plate 78; whereupon the entire frame drops by gravity,
its lower end being guided by pivot 12, depending from cross-piece 67, and passing
through eye 11 in flange of cross-tie C, and being received on rubber spring 13.
The wiper and paper-feeder being thus combined, and thus elevated and depressed
together, the wiping paper is kept under a uniform tension, and its effectiveness is
thereby greatly increased. Aud the supporting and guiding pivots 69 and 12 allow
a swivel motion to the frame, which may be regulated by set-screws 136 passing
through cross-tie Cand thus provide a delicate adjustment of the wiping surface to
the varying sizes of the dies in use.
Wiping plate is secured at its center to cross-piece 68 by screw-bolt 86,

is adjustable at four points, and its pressure on the die is regulated, by bolts 82,
passing up through cross-piece 68 and its projecting eyes 81 and pressing
against rubber springs 84, resting in cups 83, depending from the under side of
the plate. Passing through side bars 89 at either end of the wiping plate m
are eccentrically journalled roller 87 and slutted roller 88; roller 87, when turned
touching the under surface of the wiper plate, and roller 88, slotted along its
entire length between the side bars, by which rollers are attached and firmly
secured the felt or other material customarily covering the wiping plate in the
following manner: Roller 87 being sufficiently turned inwardly, the end of the
felt is passed between it and the upper plate, and the roller is then turned
back, catching the felt as in a vice; the other end of the felt is carried over
plate and passed through the slot in roller 88, which is then turned until

page_text: the end of the felt is caught under and secured by the surrounding fabric, and
the whole sufficiently stretched, when roller 88 is fastened by a jam nut.
Over the wiping surface thus prepared passes the wiping paper froin supply
roller 90, (removable by merely turning latches 91), through feeding rollers 92
and 93, to the take-up roller 94. The paper feeding operation is thus performed:
Attached to the inner side of the frame 66 by studs, which pass through
slots 133, is rack-bar 95, having teeth opposite the journals of rollers 94 and 92,
which engage with the tecth of sectors 97, turning loosely on said journals, and
carrying pawls 98, which (by aid of springs 137) engage with ratchet wheels 99,
keyed to roller shafts. When the die has been wiped and hook 77 thrown off,
bevel cam
75 pressing upon roller 134, pushes down rack bar 95, which
simultaneously turns the feeding and take-up rollers. To regulate the quantity
of paper fed, ring 100, carrying flange or hood 101, is adjustably secured to the
eye forming the bearing of the feed roller journal, and the location of the hood
in respect of the ratchet wheel determines which tooth of said ratchet wheel the
pawl shall engage with, and by consequence the extent to which the feed roller,
firmly keyed to its shaft, shall turn. The take-up roller runs loosely on its shaft,
being carried along by friction, regulated by thumb nut 135 to the strength of the
paper; and whilst its shaft turns a uniform distance at each downward movement
of the rack bar, the roller itself turns only enough to take up the waste paper fed
to it. When the pressure of cam 75 is removed, rack bar 95 is retracted by
spring 96, until it is in position for another feed movement.
