PRINTING DEVICE FOR PAPER-ROLL HOLDERS.

SPECIFICATION forming part of Letters ?atent No. 596,891, dated January 4, 1898. 1

Application filed April 23, 189 '7.

To aZZ whom may concern.-

Be it known that 1, CHARLES H. Lone, a citizen of the United States, residing at Tipton, in the county of Cedar and State of Iowa, have invented a new and useful PrintingDevice for Paperdtoll Holders, of which the following is a specification.

The invention relates to improvements in printing devices for paper-roll holders.

The object of the present invention is to improve the construction of printing devices for paper-roll holders and to provide a simple, inexpensive, and eificient device adapted to be readily applied to the ordinary paperroll holder and capable of printing advertising or other matter on the paper as it is unreeled for use.

The invention. consists in the construction and novel combination and arrangement of parts, as hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is an elevation of a printing device for paper-roll holders, constructed in accordance with this invention. Fig. 2 is a side view of the same.

Like numerals of reference designate corresponding parts in both figures of the drawings.

l designates a substantially rectangular.

supporting-frame, comprising similar sides 2 and an upper or inner cross-bar 3, which is rounded and journaled in suitable bearings 4 of clamps 5. The clamps 5, which are provided with rigid jaws, are adapted to receive and engage the main frame of a paper-roll holder, being provided with set screws 6 at their upper jaws for engaging the main frame,

and they are provided with perforated ears to form the bearings 4, and the cross-bar 3, which is arranged in the perforated ears, serves as a pintle and hinges the frame 1 to the clamps.

A printing-roller 7, which is provided with suitable journals, is mounted at the lower or outer end of the supporting-frame 1, thejournals being formed by a rod 8, which passes through the sides of the frame, being provided at one end with a head and at the other end, which is threaded, with anut. The printingroller, which is provided on its engaging face or periphery with suitable type, frictionally Serial No. 633,472. (Remodel) and comprising a central loop 14, located at the center of the cross-bar of the supportingframe 1 in position for engaging the main frame of aholder, reversely-disposed springcoils 15, located at the ends of the loop 14 and disposed on the cross-bar 3, and the spring-arms 16, extending from the outer ends of the coils and terminating in laterally-disposed hooks 17, which engage over the upper or outer edges of the sides 2 of the supportin -frame. This spring 13 holds the print ing-roll in yielding engagement with the roll of paper and produces sufficient pressure to produce a perfect impression of the type.

The inking-roll is capable of adjustment, the rod 10 being arranged in slots 18 of arms 19, which extend upward from the sides of the frame 1 at an acute angle to the same. The upper ends of the arms 19 are provided with threaded longitudinal openings receiving'set-screws 20, which engage the ends of the rod 10 and are adapted to force the same downward in the slots 18. v

It will be seen that the printing device is exceedingly simple and inexpensive in construction, that it is adapted to be readily applied to any ordinary paper-roll holder, and that it yieldingly engages the roll of paper with suihcient pressure to produce a perfect impression of the type, so that an advertisement or other matter may be properly printed on the paper as it is unreeled from the roll.

What I claim is- 1. A printing device for paper-roll holders comprising a pair of clamps adapted to engage the frame of a paper-roll holder and provided with perforated ears, a substantially rectangular frame journaled in the perforated ears, whereby it is hinged to a paper'- roll holder, a spring composed of spring-coils disposed on the crossbar of the frame, a central. loop connecting the spring-coils and arranged to engage a paper-roll holder, and the spring-arms extending from the coils and engaging the sides of the rectangular frame, and the printing and inking rolls carried by the latter, substantially as described.

2. A printing device for paper-roll holders comprising a substantially rectangular supporting-frame provided with angularly-disposed arms, the latter being slotted and having threaded openings communicating therewith, clamps adapted to engage a paper-roll holder and provided with bearings receiving the supporting-frame, a spring engaging the
