Specication of Letters Patent.

Patented July 30, 1907,-

Original application led March 17', 1905, Serial No. 250,526. Divided and this application filed August 10, 1906. Serial No. 330.071.

To all whom it may concern:

Be it known that I, EDWARD B. ROTH, a citizen of the United States, and a resident of the city of St, Louis and State of Missouri, have invented a new and useful Improvement in Embossing and Printing Presses,

of which the following is a specification.

My invention relates to printing presses and especially to embossing and printing presses, and has for its principal object to secure uniformity in the inking of My invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawing, which forms part of this specication, and wherein like symbols refer to like parts wherever they occur, Figure I is a side elevation of so much of the embossing and printing press as relates to the inking thereof; Fig. 2 is a detail vertical view, partly sectional, illustrating the mounting and movement of the ink-roller; Fig. 3 is a detail plan view of the part shown in Fig. 2 Fig. 4 is a vertical sectional view through the ink receptacles and feed rollers on the line 4-4 of Fig. 3; Fig. 5 is a vertical sectional detail on the line 5-5 of Fig. 3; Fig. 6 isa detail perspective view of the separated members of the track which constitutes the guide for the ink-roller; Figs. 7 and 8 are detail views of one of the hangers in which the ink-roller is mounted; Figs..9 and 10 are detail views Aof one of the crank arms which operate the arms which carry the ink roller. y

This application is a division of another application for patent for embossing and printing presses filed by me March 17, 1905, Serial No. 250,526, to which reference is hereby made for more particular description of the machine to which the improvements herein described relate.

The frame of the machine comprises and rests upon a base l. From said base rise columns 2, which are similar to each other. Each column comprises a bifurcated bottom portion having converging legs 3, 4 which are joined by a substantially horizontal part 5. From the bottom portion rises a channeled portion G which is closed at the top by a plate 7 provided with a bearing 8. A horizontal table l0, comprising parallel members 1I, is mounted on the frame and extends rearwardly.

In the lower portion of the columns, bearings are provided for a power shaft 14. Parallel with said power shaft, a main shaft is jom'naled. A pinion 14XL on said power shaft meshes with a spur gear 15a on said main shaft. Y

In the channeled portions of the columns 2, 2 extend pitman rods 27. These rods extend at their upper ends through bearings 8 in the plates 7 which cap .the columns. At their lower ends the pitman rods carry cam straps 28, the latter being secured by nuts 29, 30. Bearing blocks 31 are provided on the lower sides of the cam straps where they are engaged by cams. At their sides the cam straps are equipped with bearing surfaces which have sliding engagement with corresponding bearing surfaces on the side walls 23 of the oil chambers, which form, in effect, slideways to guide the cam straps. Toe-cams 32 are mounted'on the ends of the main shaft 15 and coperate with the cam-straps, bearing on the bearing blocks 31.

At their upper ends the pitman rods are connected to opposite ends of a cross-head 33. The ends of the cross-head have sliding bearings in the upper parts of the columns. Compression springs 34 surround the pitman rods 27 and bear at their upper ends against the ends of the cross-head. At their lower ends they rest upon adjustable tubular seats 35 which have screwthreaded engagement with blocks 36 integral with the columns. The springs tend to sustain the cross-head at the upper limit of its movement .and hold the camstraps always in engagement with the toe-cams. vibration, due to the motion of these parts, is almost wholly avoided.

The embossing die is horizontally reciprocated. It is carried rearwardly to be inked and forwardly to be wiped and for the impression to be made in coperation with the counter. The die is carried by a chuck 53 mounted on a table 54 which moves in ways in the parallel members 11 of the table l0 above referred to.

. The mechanism for reciprocating the table will be first described. Upon the main shaft 15 and about midway between its bearings an eccentric 55 is secured. A lever 61, pivotally mounted on the base l, is connected with the eccentric strap by means of a skeleton pitman 62. The pitman is rigidly connected to the eccentric strap and is pivotally connected to the lever. At its upper end the lever 61 is pivotally connected to a block 63 on the reciprocating table 54 by means of a link 64 which is pivotally connected to both. Said block 63 is provided with a tapering recess and a wooden block is seated in the bottom of the recess. A stop pin 65 is adjustably mounted in the beam 9 of the frame, with which it has screw-threaded engagement. A set nut 66 is provided to lock the pin in any position of adjustment. The chuck 53 comprises a base having a substantially cylindrical flange 67.

Thus, i

Two clamping pieces 68, having rabbeted inner edges left-hand screw 70 is secured. Clamping plates 7l fit over the said raised portion of the base and have their ends rabbeted to fit the rabbeted edges of the clamping pieces 68. These clamping plates have screw-threadedengagement with said right-and-lefthand screw 7() whereby they may be caused to approach or recede from each other. The embossing die is clamped between said clamping plates '71 which are in turn. clamped down by the clamping pieces 68. The chuck 53 can be rotated through a small angle so as to set the die in such direction that the direction of movement of the wiping paper shall be across the lines. The chuck is secured to the table by screws 724 Two holes73 are provided in the reciprocating table, in either of which the screws may be inserted.

The inking mechanism is arranged on the table 10 at the rear thereof so as( to ink the die during the rearward portion of its travel, Standards 74 rise at each side of the table from the members 11. At their upper ends said standards have bearings in which a rock shaft 75 is journaled. A slotted crank arm 76 is secured on one end of said rock-shaft by a set screw 77. An adjusting screw 78 extends longitudinally of the slot in said crank arm and is secured against longitudinal movement therein by means of a collar 79 and a head 80. A squared block 81 is slidably mounted in the slot in said arm and has screw-threaded engagement with said adjusting screw whereby it may be adjusted to any position in said slot. On 'one side the block 81 carries a crank pin 82. On the other side, the block is provided with a screw on which a set nut 83 is mounted. The actuating rod 84 for the ink-roller is pivot-ally connected to said crank pin 82. At its lower end said rod is provided with a roller which engages a cam 85 on the main shaft 15. The rod is supported at its lower end by a link 86 which is pivotally connected to the frame of the machine. By adjusting the block 81 on the crank arm 76, the point of connection of the actuating rod 84 is adjusted and thus the angle through which the rock shaft is turned may be varied.

A frame 87 is secured to the rock-shaft 75 and is provided with parallel arms. At the ends of the arms angular members 88 are pivotally mounted. Said angular members have upper portions extending substantially parallel with the arms. A pin 89 secured in the arm passes through the angular member. A spring 90, surrounding said pin and bearing at one end upon the nut 91 on the end of said pin and at the other end on said angular member, tends to hold said upper portion of said angular member and said arm in contact. A screw 92 is adjustably mounted in said angular member to determine the minimum distance between said upper portion of said angular member and said arm. The other end of said angular member is divided into v two parts; one part 93 is fixed and the other part 94 is pivoted thereto. The exterior surface of the split portion is tapering. A ring 95 is mounted on such tapering surface to hold the parts together when it is desired to do so. A spherical bearing 96 is formed in i the two parts 93, 94, and in such bearing a zonal seg- 60 ment of a sphere or a ball 97 is mounted. This ball is pierced by a cylindrical hole which forms a bearing for the reduced end of the ink-roller-shaft 98.

At the rear end of the table an ink-pan receiver 99 is permanently mounted. lts sides provide bearings for the shaft of the feed-roller. 1n this receiver the ink-pans or ink-receptacles are set. These pans may have one, two or more compartments, depending on the colors in which different portions of the impression are to be printed. In the case chosen for illustration the ink-pan 100 has three compartments separated by partitions. The partitions are slotted in a manner corresponding to the bearings in the ink-pan 'frame 99. A feed roller 101 is used having as many cylindricalvsections as there are compartments in the ink-pan mounted on a shaft 102. This is journaled in the inkpan receiver and the sections depend into the ink-pan. Between the sections shields 103 are mounted on the shaft. These shields are re-bent sheet metal plates which straddle the partitions ofthe ink-pan and serve to prevent the ink in one compartment being carried into the next compartment through the slot in which the shaft 102 rests. On the other end of the feedroller-shaft a sprocket 102iL is mounted. This is'connected with a sprocket 104 on the power shaft by a sprocket chain 105. Thus, so long as the machine is running the feed roller will be rotated.

To prevent too much ink being carried up by the feed-roller, scrapersl are provided. A bar 106 is secured t0 the ink-pan frame. To this bar asV many scrapers 107 are secured by screws 108 as there are compartments in the ink-pan. Each scraper has a flange 109 on its rear edge in which two screws 110 are secured. The screws 110 enter holes in the bar 106. By means of the screws 110 the scrapers can be adjusted transversely and-angularly and thus their edges can be adjusted exactly parallel with the sections of the roller. 1t is desirable to have the scrapers thus independently adjustable because the different colored inks have different consistencies. Hence, the scrapers may be set at different distances from the different sections o`f the ink-roller. When only one color is being used, 0f course, it is unnecessary to use a pan with more than one compartment.

Curved tracks 111 extend forwardly from the ink-pan frame to guide the ink-roller. On either 'side of the die chuck 53 adjustable tracksare arranged. The latter comprises a base plate 112 having a horizontal lange through which screws pass to secure it to the reciprocating table 54. The upper edge of the base plate is inclined and near said edge are arranged slots `113 parallel therewith. .A track-carrying plate 114 is secured to the base plate by means of screws passing through said slots` The track-carrying plate has an inclined shoulder 115 having the same inclination as the inclined edge of the base plate and resting upon said in clined edge. Thus, the tread of the track carrying plate will be parallel with the surface of the reciprocating table 54. By this arrangement the track carrying plates 114 can be raised and lowered without affecting the horizontal alinement of their upper surfaces. Upon each of the track carrying plates 114 is mounted a sectional track. The track sections 201 are preferably angle pieces having one flange resting on the track carrying plate and having its other flange secured latwise to said plate by means of bolts extending through elongated horizontal slots provided therefor in the track carrying plate. By this arrangement, each of the track sections can be adjusted longitudinally of the track-carrying plate independently of the other section, so that a space of any desired length may be left between the adjacent ends of said sections and such space may be located wherever' it is desir'ed. llre track sections are comparatively thin plates and the upper edges of tlreir adjacent ends are rounded or beveled off to prevent a jerky motion of the ink-rollers which travel thereon. In practice, the track is adjusted at such an elevation that the inkr'oller' thereon will just clear the die, but the ends of the track sections are positioned to slightly overlap the edges of the die or to overlap such portions of the die as it is desired not to ink. In consequence of this arrangement, the ink r'oller travels clear of the edges of the die and then bears downwardly on the top of i'ace oi' the die and again rises therefrom without inking the opposite edges of the die. This construction not only economizes ink and wiping paper', but produces superior work, because it removes the danger heretofore common of getting the hard gummy ink from the edge of the die onto the face thereof.

The ink roller shaft 98 carries an ink-roller 11G and near its ends guide rollers 117. The guide rollers run on the cur'ved tracks 111 and the track plates and thus hold the ink roller in the position desired. By adjustment of the track-carrying plates 114 the pressure of the ink-roller' upon the dies can be regulated and var'iations in the thickness of the dies may be provided for. The cur'ved tracks 111 serve to guide the ink-roller so that it will properly engage the feed-roller and will run onto the track plates smoothly. The springs 90 hold the ink-roller yieldingly in contact with all the parts the latter engages. The angular member's 88 being independently mounted and the ink-roller shaft being' mounted in a ball-and-socket bearing, the inkroller can adjust itself within limits, to any surface with which it engages. This is a matter of much importance as it insures the proper inking of the die although the latter' may have been slightly tilted in some way.

An arm 118 is loosely secured to the rock-shaft 75. A rod 119, provided with a handle 120, and a catch 121, is pivotally connected with said arm. By means of this rod the ink-r'oller' and its actuating rod 84 may be raised so that they cannot be actuatedby the actuating cam 85, the catch 121 engaging the bottom of the notch in the beam 41 through which the rod extends. The ink-roller is thrown into this position when the counter is being hammered up. v
