. Application filed October 12, 1905. Serial No. 282,866- I of theUnited States of America, and a resident of Cincinnati, county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Presses for Printing Finished Pails, of which the following is a specification.

My invention relates to improved mechanism for printing trade-marks and other matter upon the exterior of cans and buckets. l

' One of its objects is to provide mechanism which will print upon the exteriors of cans or buckets after the same are completed, thereby avoiding any liability to injure the printed matter by subsequent operations.

Another object is to provide improved mechanism for transferring the ink from the type to the cans and insuring a uniform movement thereof.

Another object is to provide improved means for stopa ping and starting the printing mechanism.

Another object is to provide improved mechanism for receiving and holding the can, or bucket during the operation.

' It further consists in certain details of form, combina- Fig. 5 is a detail of the ratchet wheel and pawl for lockat the sides of said disk. 5 0

ing the impression transmitting cylinder its driving gear. Fig. 6 is an enlarged detail end View of the transmitting cylinder. Fig. 7 is a detail end view' .of one of the starting clutch member s. Fig. 8 is an enlarged detail viewof'the clutch releasing mechanism. Fig. 9 is an' end view of the bucket supporting drum. Fig; 10 isasection through the same on line x. t of Fig. 9.

Fig. 11 is a view similar to Fig. 9 showing a 'modified form of drum or cylinder. Fig. 12 is a section through the same on line of Fig. 11.

In the accompanying drawings, A, represents the frame of the machine, the table, A, of which is provided with horizontal ways, or, upon which travels a frame, B, which carries a type-frame, b, which is clamped thereon by means of set-screws, bi This frame also carries an inking disk, b andcam plates, b

The frame, B, is provided on its underside with a rack, B, which is engaged by a gear, 0, on the shaft, 0, which shaft is journaled in brackets, c, secured to the underside of the'table, A. On the shaft, c,- is also mounted a'gear, 0 which is engagedby a segmental gear, D. This segmental gear is reciproc'ated by means of a crank-arm, d, projecting from the hub of the segmental gear, apitman, d, and a crank-arm, d mounted on the shaft, E, by which mechanism the frame, B, is

reciprocated backward and forward upon the-ways, a,

of the table, A. 0 represents rollers carried by the shaft, 0, and supporting the frame, B, at opposite sides of the gear, 0.

Mounted on the table, A, above the frame, B, are a pair of ink rolls, F, F. These rolls are permitted to yield upward by means of springs mounted'in the housings, f. The ink is spread upon'the disk, b and as the disk passes beneath the rolls, F, F, the cams, b lift the rolls until they reach the central portion of the disk, I), when they are allowed to rest upon the face thereof and again lifted when the disk is moved in the opposite direction. The rolls, then by contact with each other, distribute the ink over their surfaces and also upon the face of the type in the type-frame, I). Also mounted upon the table, A, is a semi-cylindrical transfer plate, G, the shaft, g, of which carries a'gear, g, which engages a rack, 9 mounted on the frame, B. The plate G, is faced by an elastic pad, G, which pad is secured at one edge of the segment and is drawn over a shaft, or roller, 9 at the opposite edge, where-it is strained or locked in place by means of a ratchet wheel, g and pawl, 9 The gear, g, is loosely mounted upon 'the shaft, 9, and carries a spring actuated pawl, 9 which engages a single-toothed wheel, 9 rigidly mounted on the shaft. Thus, the gear, g, is free to rotate, While the cylinder, G, moves in one direction only, with a step by step movement through the engagement of the pawl, g, with the wheel, g this movementbeing timed with the forward movement of the frame, B. 1

H, represents a shaft mounted in bearing, h, and carcans or buckets, are mounted to be printed. This correspond with the movement of the transfer cylinder,,

G. Thus the impression from the type will be transferred to the face, G, of the cylinder, G, and from thence to the face of the can, which is supported on the cylindei, I, after, which the parts move to a position so that the segment, G, is clearof the face of the bucket and the bucket may be removed and a fresh one substituted. 1

, Where it is desired to print upon the face of a tapered bucket, I preferably employ a drum, I, of the form shown in Figs. 9 and 10, having a segmental tapered face, i, to support that portion of the can to be printed and a spring-arm, i, which serves to strain the bucket in place upon the drum, I, and permits the same to be readily pushed into place and removed.

Where it is desired to print upon cylindrical cans or buckets, or those having a reduced neck, such as shown in Fig. 12, I preferably provide a cylindrical drum, J, having a section, j, rigidly mounted on the shaft, H, and a movable or collapsible section, j, to perniit the straining or clamping and removal of the can or bucket. The movable section, j, may be variously operated to effect the desired purpose.

As shown in Figs. 11 and 12, K represents a shaft mounted in bearings in ears, j on the frame, j, and

provided with an eccentric portion, k, which engages the cars, 70, of the section, j, so that the partial rotation of shaft, K, serves to expand or retract the movable section, 3. 7' represents bolts projecting from cars, is, through guide slots, 3' in cars, P. The adjustment of section 3', is preferably effected by means of a cross-arm, j carried by the shaft, K. One end of this cross-arm is provided with a stud, k which may be conveniently grasped by hand to expand the section, 9" after the can has been set in place and may be automatically thrown to retract section, 9', by projecting arm, 70, carried by the bracket, h, the opposite end of the cross arm, k serving by engagement with the shaft, H, to limit the movement of the shaft, K.

The various operative parts are driven in the following manner: L, L, represent tight and loose pulleys on the main driving shaft, Z. Z, represents a gear on the shaft, Z, which in turn drives a gear, a, loosely mounted on the shaft, E. e, represents a clutch member carried on the sleeve forming the hub of the gear, e, and is continuously .otated thereby. 0 represents a clutch member splined to the shaft, E, and normally pressed into engagement with the clutch member, e, by means of coiled springs, e engaging recesses, e, in said clutch member, and also in a collar, a e, represents a camgroove in the face of the clutch member, e which is engaged by a stud, or pin, m, seated in the housing, In, and actuated by a spring, m to hold the pin, m, in the cam-groove, 6 m represents a pin on the treadle or starting lever, M, which engages the collar, m at the lower end of the pin, in, so that the depression of the lever, M, by the foot of the operator, will force the pin, m, from the groove, e, and allow the spring, a, to force the clutch members, e, 0?, into engagement with each other, causing the shaft, E, to revolve. As soon as the lever, M, is released, the pin, 17%, springs upward, entering the cam-groove, e, and upon passing the diagonal portion thereof, throws the clutch member, a,

towards the collar, 2 and stops the movement of the machine until the can has been removed and another one substituted, when the lever, M, is again depressed. 0 represents a cam carried by the clutch member, e, which is engaged by a roller, n, pivoted at the lower end of the lever, 72/, which lever is pivoted at n to a bracket on the underside of the table, A. The upper end n of the lever, 11/, serves as a pawl, or dog, to enter a notch, n, in the wheel, n rigidly mounted on the shaft, 9. Thus the movementof the cam, e", retracts the dog, a from the notch, n, of the wheel, n unlocking and permitting the revolution of the shaft, g,

' which is again locked as soon as the notch, it, comes into position to receive the dog, 17?, which serves to insure that the shaft, g, and its transfer cylinder, G, shall come to a stop always at the same position. The cam 0 is so shaped that it causes the pawl, 11. to engage the notch, n immediately after the end of the forward movement of the type plate, b, and just at the time it is making its return movement, so that the transfer cylinder is always held in the same relative position to the type-plate, to insure that the impression made by the type upon the transfer cylinder shall always come at the same place.

The mechanism herein shown and described is capable of considerable modification without departing from the principle of my invention.
