PRINTING ATTACHMENT FOR ROLL-PAPER HOLDERS.

ivPEGIFICATION formingpart of Letters Patent No. 737,822, dated September 1, 1903.

Application filed April 15, 1903. Serial No. 152,702. (No model.)

To ctZZ 1072 0712, it may concern.-

Be it known that I, RICHARD E. BRUNACCI, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement; in Printing Attachments for Roll-Paper Holders; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to improvements in devices that are intended to be attached to a wrapping-paper-roll support or rack and which devices are adapted to print the name or an advertisement or other matter upon the wrapping-sheet as it is unwound.

Its object is to provide a simple compact printing and advertising machine adapted to receive printing and inking rollers of different diameters and lengths and having various tension devices for adjusting it to the several rolls and to the paper-roll as the latter is diminished.

It consists of the parts and the construction and combination of parts hereinafter more fully described, having reference to the accompanying drawings, in which- Figure 1 is a side elevation, in partial section, of my invention. Fig. 2 is aplan view of same. Fig 3 is a detail printing-roll journal and modification fink-rolljournal. Fig. at is a side view of printing-roll. Fig. 5 is a transverse section of same.

A represents an ordinary rack or holder in which is suitably supported the roll of paper 2, adapted to be unroiled and to have portions severed therefrom as needed.

My attachment, which is actuated by the unwinding of the strip to be torn oif to print a label or other characters at suitable intervals along the length of the strip, is secured to the cross-rail of the holder above the roll by means of the clamps 3. The latter are perforated to receive a rod 4, threaded at the ends and retained in position by means of the nuts 5.

The rod is centrally supported by a bracket 6, secured to the cross-rail of the rack and having a vertical portion grooved or otherwise constructed to offer a secure seat to the adjacent ends of the helical springs S, which surround the rod between the bracket 6 and each clamp 3. The other ends 9 of springs 8 aresupported on inwardly-extending notched projections 10 on the arms 11, which latter are'journaled in brackets 3 and carry at their outer ends the respective printing and inkdistributing rollers 12 13.

The function of springs 8 is to press the printing-roller 12 always against roll 2. The pressure of the roller may be increased or diminished by slipping the ends 9 of the springs off of projections 10 and giving an additional turn or two to the springs, or vice versa, according to the effect desired.

The journal-boxes on the ends of arms 11, supporting the printing roller shaft, are each formed with a hinged section 14, as in Fig. 3, normally locked in closed position by a removable plate or keeper 15 By loosening the latter the boxes may be opened to allow the printing-roller to be quickly removed and another put in position.

The two arms are braced intermediate of their ends by means of the removable crosspiece 16.

This construction of separable parts is advantageous, inasmuch as it enables the same set of arms, clamps, and bracket to be used in conjunction with a variety of styles and sizes of printing-rollers, it simply being necessary at the time of putting in a longer or shorter roller to substitute for the rod 4 and brace 16 other rods and braces of a length corresponding to the new roller.

The ink-distributing roller 13 in Fig. 3 is shown as carried by arms 17, which extend beyond and parallel with arms 11 and are slidable in guides 18 on the sides of arms 11. A spring 19 surrounds each of the arms 17 between its guides 18 and has one end acting against one of said guides and the other against a collar 20 on the arm to draw the distributing-roller into engagement continually with the printing roller 12. The latter has a portion of its surface, as 21, provided with raised type or other inscribing means, while the remainder of the periphery intermediate of the segmental rings 22 at each end of the roller is covered with cloth or other suitable absorbent material which carries a sufficient quantity of ink to keep the distributing-roller 13 moist.

Roller 13 runs in the space between the rings 22, and with each revolution of the roller. 12 the former traverses the portion 21 to suitably supply the type with ink. By this system of inking the type there is little or no danger of depositing too much ink on the type at any one time, and so cause a blur in the printing.

The rings or guides 22 are coincidentin length with the cloth-covered portion of the roller and form tracks to support that portion out of contact with the paper-roll, so as not to allow the paper to become smeared with ink. The space between the ends of each track is occupied by the raised type portion. 21, and with each revolution of roll 12 the type are brought into intimate contact with the paper-roll to leave the desiredimpress.

In Fig. 3 is shown a second method of supporting the distributing-roller in relation to the printing-roller, as where it is desired to compress the device into as small a space as possible. Herein the shaft of roller 13 is supported in removable journal-boxes 23, supported directly on the arms 11 and having spring means, as 24:, for the purpose of keeping the two rollers in constant contact. The rollers may be suitably incased by a removable housing 24 to protect them from dust and damage.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. An adjustable roll-paper-printing device, comprising in combination separate clamps, a removable rod connecting said clamps, spring-actuated arms hinged in said clamps, removable intermediate connections between said arms, hinged journal-boxes carried by said arms, a printing-roller supported in said boxes, and a spring-actuated distributing-roller.

2. The combination in a roll-paper-printing device, of clamps, a removable rod connecting said clamps, arms hinged on said clamps, said rod forming the hinge-pivot therefor, removable interconnecting means for said arms, a spring-actuated printing-roller journaled on said arms, and parallel offset spring-actuated extensions on said arms, and a distributing-roller carried by said extensions.

3. The combination with a paper-roll holder, of a printing attachment comprising removable clamp members, a removable rod journaled in said members, a bracketsupporting the rod intermediate of said members, arms pivoted to said brackets, said arms having hinged journal-boxes, a printing-roller journaled in said boxes, an ink-distributing roller, lateral notched projections on said arms, and springs surrounding the aforesaid rod and having one end engaged by said bracket, and the other supportedon said projections to retain the roller in contact with the paper-roll.

4. The combination in a roll-paper-printing device, of a yielding support, a printing-roller carried thereby, annular segmental guides upon the periphery of the roller in the space unoccupied by the printing portion of the roller, whereby all but said printing portion of the roller is maintained out of contact with the surface to be printed, and a distributingroller traversing the space between said guides.

5. In a printing device, the combination with a suitable support, of a printing-roller, annular segmental spaced guides or tracks on the periphery of the roller in the space unoccupied by the printing portion thereof, an absorbent ink-containing covering for the roller intermediate of said guides or tracks, and a resiliently-supported distributing-roller traversing said covered space and printing portion.

In witness whereof I have hereunto set my hand. I

RICHARD E. BRUNACCI. Witnesses:
