vApplication iedumh 23,1894. serial N0.5o4.863. (umbau.)

To all whom it may concern:

Be` it known that we, JOSEPH YARDLEY JOHNSTON and BRoR F. BEReH,'citzens of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvenients in Embossed-Printing Presses; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in presses for embossed printing, and more particularly to improvements in the press covered by Letters Patent of the United States, No. 504,680, issued the 5th day of September, 1893, to Joseph Yardley Johnston. The basic elements of the Johnston press-the springactuated screw plunger, the revolving die, and the spring-and-camactuated inker and wiper-are retained, and the present invention consists in novel and improved arrangements and constructions of these fundamental parts and of the mechanism operating them, as hereinafter fully described, with the result of increasing the lspeed of the press, diminishing the expense of operating it, and greatly augmenting the perfection of its work. We attain these objects by the mechanism illustrated in the accompanying drawings, in which-- Figure I isa front elevation of an embossed printing press embodying 'our said improvements. Fig. II is a side elevation of the upper part of the press. Fig. IIIis a plan view of the upper part of the press. Fig. IV'is a sectional side elevation, showing the operative connection of the principal parts. Fig. V is an under side view of the die block and holder. Fig. VI is a side elevation of a gage for longitudinally adjusting the die in the die holder. Fig. VII is a side elevation of one of the jaws holding the die. Fig. VIII is a side elevation ofthe locking pin, which arrests the die-carrying arm in its revolution. Fig. IX is the lever which in part operates the said locking pin. vation of the cam which actuates the locking 5o pin, showing its relation to the teeth of the lsupporting bracket.

Fig. XXIX is a perspective view of the forked lever which actuates the ink agitator. Fig. XXX is a vertical section through the standard, T-shaped supporting sleeve, and sprocket wheels which transfer motion to the inking device.

Figs. XIX and XX show de Similar letters and numerals designate the corresponding parts in all the figures. v

A is the frame of the press, having the base a, and being. provided with the arms l, 2, and 3, supporting the driving mechanism. The press frame is mounted upon a suitable stand B, having the cross-tieC, provided with the flange b, which supports the paper-feeding and wiping device as hereinafter explained.

D is the main shaft, located centrally near the top of the press, andcarrying thegdriving pulley E, loosely mounted thereon, but'withroo out lateral play. The movement of themain shaft is controlled by handle 9, in connection with an incline not shown, spring 10, and rod 8, having the forked arm 7, whereby the sliding clutch 6 is moved 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.l Motion is transferred from shaftD to shaftF 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 t cause one complete revolution of pinion Q, and by consequence of revolving arm G, at eachrevolution of cog-wheel T, and are so disposed that the blank portion 14 of the gear is presented to pinion Q while the operations of locking and unlocking the revolving arm and striking the impression blow are being performed.

Revolving arm Gis 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 I. Lever I is pivotally attached to bush 19,

its forward end resting in slot 2O of the lock-l ing-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 2l and 24 of cam K, by which respectively the locking pin is raised just be fore 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 g 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 is adapted to fit snugly in the space between the two ngers.

Die block 28 has on its under side a transverse dove-tailed groove 30, and sliding in it the correspondingly dove-tailed tenons 30 of the two

jaws

29 and 29. These tenons form suitably threaded nuts for the rightandleft hand screw 31, supported by plates 32 and 32', and serving to move the jaws (which hold die d) conjointly in andout from a common center. For centering the die longitudinally is provided the gage 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 gage is flush with the bottom ofthe die block, but the projecting shoulder 35 catches the die and thus accurately centers' it longitudinally. lOn base plate a of the press, and directly beneath screw plunger 3S,

rests the movable counter plate @,held in' place by dowels or otherwise, upon which the counter or counter die is built up. This movable counter plate, in conjunction with the sliding jaws and gage, 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 inner end being secured to sleeve 41, which is keyed to the plunger, and its outer end resting loosely against lug 42 of ring 43, lying movably 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 roller 55. 4

Superimposed on sleeve 4l, and surrounding screw plunger 38, is hub 47 of cog-wheel 5l, located in the upper part of the casing, and revolved by pinion 50, carried at the top of shaft 48, which is supported inbush 49, and driven by bevel wheel X'on its lower end and bevel wheel V on main shaft D. Cowheel 51 carries a tripping bolt 62, adj'ustably located in slot 63, and the depending sleeve 52. Surrounding sleeve 52, and at the same height above the bottom of the casing as link56, 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. On the exterior surface of ring 53 is 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 6l, supported by standard 46, rising from the floor of the casing.

In operation, the forward end of elastic shoe 54, carried by sleeve 52 of revolving cogwheel 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 0E shoe 54 by finger 6l, 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 pluugers rebound, the forward end of shoe 54 again catches shoulder 5S, its elasticity preventing jar, and the operation as just described is repeated. The tension of the coilspring, 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 n being supported by shank 102, resting on coilspring 104, whose heightV is ladj usted by thumb-nut 105, in sleeve 103, sustained by bracket O, suitablylattachedy 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 on a short shaft, which also carries ink agiltator 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 are facilitated. The journals `of the shafts of the evener 110 and the inking roller 111 rest in holes located eccentrically in stationary plugs 113; whereby their pressure on the collecting roller is regulated and their removal and replacement are 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 P, attached to the base of the press frame; at the other end of the shaft turning in sleeve 129 is sprocket wheel127, which transfers the motion by chain 126 to sprocketwheel125, fastened to one end of shaft 128, turning in sleeve 123, attached to the casing of theinker; at the other end of shaft 128 is bevel pinion 124, which gears with bevel pinion 117, attached tothe outer end of rotatingplug 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 112', upon which the outer ends or

cams

39 and 39 of

jaws

29 and 29 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-spring 101.

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 car-k ries the paper-feeding apparatus and wiper, and being the lever which supports it all by means of the ball-shaped pivot 69, downwardly projecting from the center of crosspiece 68 into a suitable socket in the lever. The outer end of lever A70 lies between and is attached by pivot 7l to the forked ends 72 of an arm projecting from the base of the press,

the die.4 Simultaneously hook 77, which is pivotally attached to the innerend of lever 70, actuated by spring 79, catches upon plate 78, attached to arm 3, and rmly holds the wiper while the die is passing over it. The length of the wipe is regulated by tappet 80, adj ustably attached to shaft F, which 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 iiange b of cross-tie C, and being received on rubber spring 13. The wiper and lpaperfeeder being thus combined, and thus elevated and pressed together, the wiping paper is kept under a uniform tension, and its effectiveness thereby greatly increased. And the supporting and guiding pivots 69 and 12 allow a swivel motion lto the frame, which may be regulated by set-screws 136 passing through cross-tie C, and thus provide a delicate adjustment of the wiping surface to the varying sizesof the dies in use.

Wiping plate m is secured at its center to cross-piece 68 by screw-bolt 86passing up through ball-pivot 69, which is hollow, into the projection 85. It is adjustable at four points, and its pressure on the die is regulated, by bolts 82, passing up through ycrosspiece 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 journaled roller 87, its eccentric side when turned touching the under surface of the wiping plate, and

roller 88, slotted along its entire length between the side bars, by which rollers is attached and firmly secured the felt or other material customarily covering the wiping plate in the following manner: Roller 87 being suiiciently 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 vise; the other end of rthe felt is carried over-plate m and passed through the slot in roller 88, which is then turned until the end of the felt lis 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 from supply roller 90, (removable kby 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 vframe 66 by studs, which pass through slots 133, is rack-bar 95, having teeth opposite the IOO Irc'

journals of

rollers

94 and 92, which engage with the teeth of sectors 97, turning loosely on said journals, and carrying pawls 98, which (by aid of springs 137) engage withl'ratchet wheels 99, keyed to the 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-uprollers. To regulate the quantity of paper fed, ring 100, carrying ange or hood 101is 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. 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 while 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 an` other feed movement.
