MACHINE FOR PRINTING AND STAMPING VIGNETT ES.

SPECIFICATION forming part of Letters Patent No. 456,857, dated July 28, 1891.

I Application filed October 7, 1890. Serial No. 367,809. (No model.)

To all whom it may concern.-

Be it known that I, HERMANN SCHWARZ, merchant, a subject of the Emperor of Austria, and a resident of Prague, in the Kingdom of Bohemia and Empire of Austria- Hungary, have invented new and useful Improvements in Machines for Printing and Stamping Vignettes, of which the following is a specification.

My invention relates to machines for printing labels, vignettes, or patterns, upon strips of paper and cutting the printed labels or tickets to the desired shape and size.

My improvementconsists in novel features of construction hereinafter described and claimed.

Inorder that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which-- Figure I is a side elevation of myimproved machine. Fig. II is an end elevation thereof. Fig. III is a longitudinal section through the printing apparatus. Fig. IV is a front view of the printing apparatus. Fig. V is a plan view thereof. Fig. VI is a side view of a cutterroller. Fig. VII is an end view thereof.

Referring to Figs. I, II, and III, A is the printing apparatus, consisting of printing and blanket cylinders and inking and ink-distributin g rollers.

Bis the feeding device, and C shows the position of the cutting-off device. All these are operated simultaneously from aspur gearwheel a, common to all, which is driven from a crank-shaft 6 through wheels I) e (Z. The crank-shaft e is connected to the treadle gby the pitman or connecting rod f. r

The paper-feeding arrangement consists of two iron rollers 7c, geared together by means of two spur-wheels Z Z, the lower spur gearwheel Z of which is driven by the spur gearwheel a. The two feeding-rollers may be adjusted relatively to each other by the screw i. They are mounted in bearings in close proximity to and inclined slightly toward the feeding-table h. An endless band 17?. travels over the table It, passing through an inclined slot 0 and around a roller 01., located beneath the slot, and around the lower feeding-roller is. The band forms the sole connection between the band-roller n and the lower feeding-roller k and serves to introduce the paper between the feeding-rollers 7t 70'.

In the printing apparatus (shown fully in Fig. III) p is the ink or color box arranged in such a manner within the casing 19 that its position can be adjusted by the screw 19 The ink is taken from the box by the roller q, whence it is intermittently transmitted by the rollerq through the roller 1 g g to the upper printing-cylinder 'r. The printing-cylinder r and the blanket-cylinder r are geared together by spur-Wheels s and s, and are also rotated by thelargespurgear-wheel a. These cylinders are mounted in bearings in close proximity to the feeding-rollers and located in a vertical plane. The distributing-roller q is mounted on the end of a counterweight-ed lever u, pivoted at t and free to move so that the roller may be brought into contact either with the inking-roller q or with the roller The motion of the lever is obtained by a disk-cam t, which is mounted upon the inking-roller shaft and is rotated by means of a band or cord from the shaft of the large spur gearwheel a. The shaft 6 of the distributingroller is furnished with a projection t, which engages with the outer rim of the cam t. Vhen the cut-away portion of the cam is opposite the projection t", the counter-weight on the le-' ver brings the distributing-roller q'into con tact with the inking-roller q until the further revolution of the cam brings the circular part of its circumference into contact with the project-ion t and forces the distributing-roller away from the inking-roller and into contact with the roller The device for cutting off the labels or tickets consists of two rollerso and o, geared together byspurgear-wheelsw and w, and also driven by the common large spur gear-wheel at. These cutter-rollers are mounted in bearings in close proximity to and inclined slightly away from the printing and blanket cylinders. The cutter-roller o is shown in detail in Figs. VI and VII, and is furnished with anumber of curved knives r of any desired shape, and in some cases a knife or punch t is carried in addition for cutting holes in the labels for attachment to parcels. In these latter cases the roller is hollowed out, as shown at 11 to allow of the escape of the removed portion of paper orpasteboard. The distance of the printing-roller r and the cutter-rollers o from their respective lower rollers may be accurately adjusted by the screws 1" F. The printing-roller and the cutter-roller .are of equal diameters, and, being driven from the common spur gear wheel a, revolve at equal speeds, so that the labels are cut off accurately and in proper succession.

The ordinary devices may be applied for insuring the adjustment of the ink or color distributing rollers.

When the machine is in operation, the strips of paper or pasteboard, which maybe of any length, are placed upon the table 7L and are carried by the endless band m to the feedingrollerslck. Thestripsarefedforwardbythese rollers to the printing-cylinders, and after being printed, are passed on to the cutter-rollers. It will beseenthatthefeeding-rollers,printingcylinders, and cutter-rollers are close together and have their working faces arranged in the arc of a circle to operate upon a strip which passes from a horizontal table in a slightlycurved line between the feeding-rollers, printing-cylinders, and cutter-rollers, so that while these members are arranged nearly in a horizontal line they can be driven by a single large spur gear-wheel common to all and above which they are located. By the addition of further printing-cylinders and inking 0r coloring rollers labels can be printed in several different colors. The knives 12 are fixed upon the roller oby means of plates These plates have inclined edges which bear against the inclined sides of the knives, and are held securely in place by screws. By these means the knives are firmly held without interference with their edges.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent of the United States:

1.-The combination of the printing-cylinder, the ink-rollers the ink-box having adischarge-roller provided with a disk-cam, the counterweighted lever, and the ink-distributing roller mounted on the lever between the discharge-roller and the upper ink-roller and having a shaft furnished with a projection which engages the outer rim of the disk-cam, substantially as described.

2. The combination of the printing-cylinder, the ink-rollers, the casing, the ink-box within the casing, the adj usting-screw working through the casing and by which the inkboX is adjusted, a discharge-roller within the ink-box, provided with a disk-cam, the counterweighted lever, and the ink-distributing roller mounted on the lever between the discharge-roller and the upper ink-roller and having a shaft furnished with a projection which engages the outer rim of the disk-cam, substantially as described.

In witness whereof I have hereunto set my .hand in presence of two witnesses.

HERMANN SCHWARZ.
