PAPER-RACK.

SPECIFICATION forming part of Letters Patent No. 679,657, dated July 30, 1901. Application filed February 13, 1901. Serial No- 4'7,l45. (No model.)

To all whom it may concern.-

Be it known that I, FRANK WILLIAMS, a citizen of the United States, residing at Portland, in the county of Oallaway and State of Missouri, have invented a new and useful Paper-Rack, of which the following is a specification.

This invention relates to paper-holding racks in general,and more particularly to that class designed for holding paper in rolls, one object of the invention being to provide a construction which may be fitted beneath a counter or wrapping-desk, the paper being projected through a slot to permit it to be grasped, after which it is drawn out in suitable quantity and torn off against a sharp edge provided for the purpose.

A further object of the invention is to provide a construction wherein the paper will be initially projected by mechanism that may be operated with the foot, leaving the hands free for the wrapping operation.

Further objects and advantages of the invention will be evident from the following description.

In the drawings forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a top plan view of the mechanism, a portion of a counter being also shown to illustrate the relation of the parts thereto. Fig. 2 is a vertical section on line 2 2 of Fig. 1, the parts being shown in their retracted positions. Fig. 3 is a detail sectional View on line 3 3 of Fig. 2 and showing the sliding parts of the frame and drawer. Fig. 4 is a perspective view of the feed device, partly broken away. Fig. 5 is a detail sectional view showing in elevation one of the slideways in which the feed-bar of the feeding device operates.

Referring now to the drawings, 5 represents a counter or desk equipped with the present invention, and which is provided with a hinged lid 6, which carries the mechanism. Cleats 7 are secured to the under side of the lid, and slidably engaged therewith is a drawer including sides 8 and 9 and a front including an upper section 10 and an inwardly-disposed lower section 11, the sides 8 and 9 having grooves therein, with which are engaged the beads 12 on the outer faces of the side sills 13 of a reciprocatory frame including also end pieces 14 and 15. Hangers 16 depend from the sides 8 and 9, and with them is engaged a spindle 17, which carries the paper-roll 18, the paper from which is taken upwardly and between two rollers 19 and 20, rotatably mounted in the side sills 13 of the reciprocatory frame above referred to, after which it is taken over the rock-bar 21 of a feed device, then through the frictionclamp of the feed device, and then upwardly and through a slot 22 in the hinged top 6.

The feed device comprises a rock-bar 21, above referred to, journaled at its ends in bearings 24 upon the sills 13, and from which rock-bar there extend two parallel arms 25, having pivotal connection at their outer ends with one of the jaws 26 of the feedclamp, the ends of which jaw are slidably mounted between cleats 27 and 28, secured slantingly to the inner faces of the sides 8 and 9 of the drawer, whereby when the reciprocatory frame is moved in one direction the jaw will be moved forwardly and upwardly and when moved in an opposite direction the jaw will be drawn downwardly and rearwardly. 00- operating with the jaw 26 is a second jaw 26, one end of which is pivoted to the jaw 26, while the opposite end is snapped under a staple 29 on the jaw 26. These jaws are so positioned and constructed that they will have slight frictional engagement with the paper passed therebetween, so that as the jaws are moved forwardly and upwardly when the frame is moved in one direction the paper will be drawn from the rolls and the upper end thereof will be projected through the slot in the lid 6, so that it may be grasped. The paper is then drawn out in proper quantity and is torn off, a knife-edge 30 being pro vided for this purpose. This knife-edge is carried by arms 31, which are pivoted to hold the knife-edge normally flush with the upper surface of the lid 6, while at the same time permitting the knife-edge to be swung up to facilitate adjustment of the paper.

The reciprocatory frame is held normally in its retracted position by means of a helical spring 32, attached at one end to the end piece 15 and at the opposite end to the lower sections of the front of the drawer. To move the frame against the tendency of this helical spring, a rocker 35, which is U-shaped, has its ends bent outwardly and engaged in perforations in the hangers 16, and with the web of this rocker is connected a connecting-rod comprising rearwardly diverging members 36, which are bent around said web and have a treadle 37 attached to their outer ends, the forward or convergent ends of the members being pivotally connected with the end piece 14 of the reciprocatory frame. Thus, as shown in Fig. 2 of the drawings, when the treadle is depressed the frame is moved rearwardly to project the paper through the lid, and when the treadle is released the frame is retracted by the helical spring. When the frame moves rearward ly and the paper-clamp is correspondingly moved, it is of course necessary to provide means for holding the paper with relation to the top 6 so that when the clamp next moves forwardly it will project the paper. For this purpose a gripping plate or jaw 40 is pivoted in the opening in the top 6, through which the paper is projected and in such position that when raised to lie flush with the upper surface of the top it will contact with the straight edge to grip the paper thereagainst. The jaw 40 lies normally in its closed position, and to move it to its operative position at the proper time a finger 41 is secured to the under side thereof and has a cam 42 at its lower end, the cam being positioned for engagement by the corresponding surface 43 on the end piece 14 when the re-v ciprocatory frame is in its retracted position to hold the jaw 40 raised. When the frame moves forwardly to project the paper, the finger is released and the jaw 40 drops to permit the paper to feed. With this construction it will be seen that after the treadle has been depressed to project the paper the desired quantity may be drawn out, and the treadle may be then released to permit the parts to return to their normal positions and ready for another feed of paper.

It will be understood that in practice various modifications of the specific construction shown may be made and that any suitable materials and proportions may be used for the various parts without departing from the spirit of the invention.

What is claimed is 1. A paper-rack comprising a roll-holder, a reciprocatory frame having jaws for engagement with the paper from the holder to project the paper, supplemental jaws adapted to grip the paper and hold it against return movement with the first-named jaws, and means in the path of return movement of the frame for operating the supplemental jaws.
