VILLIAM H. TIVY AND LEO EHRLIOH, OF ST. LOUIS, MISSOURI, 'ASSIGNORS TO THE AMERICAN ROLL PAPER COMPANY, OF SAME PLACE.

PAPER-CUTTER.

SPECIFICATION forming part of Letters Patent No. 404,321, dated May 28, 1889.

Application filed June 1.2, 1888. Serial No. 276,792. (No model.)

To @ZZ whom t may concern:

Be it known that we, WILLIAM H. TIVY and LEo EHRLICH, both of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Paper-Cutters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in ro which- Figure I is a front elevation of our improved paper-cutter. Fig. II is'a side elevation. Fig. III is a transverse section through the roller, knife, and retaining-cam.

Our invention relates to an improved ma chine for holding and cutting wrappingpaper; and our invention consists in features of novelty hereinafter fully described, and pointed out in ihe claims.

Referring to the drawings, l represents a suitable base, 2 end pieces, and 3 a top cross-V piece.

4 represents the roll of paper, having gudgeons 5 fitting in notches 6 of the ends 2.

7 represents arms extending from the end pieces, and to the outer ends of which is secured t-he knife S, and in which is `also journaled a roller, 9. The roller is located just back of the knife, with sufficient space to al- 3o low the paper to pass between them. On the outer ends of the arms 7 are projections l0, in which is pivoted eccentrically a cam-bar, ll, which rests upon the roller 9 or upon the paper, which passes between it and the roller 9. This bar is preferably provided with a handle, l2, by whichit may be turned upward to allow the paper to be inserted between it and the roller. (See dotted lines, Fig. III.) Vhen the paper has been inserted, the cam-bar is allowed to fall again upon it, -and serves to prevent the backward or retrograde movement of the paper to avoid danger of the end of the paper escaping from between the knife and roller 9, while at the same time it does not prevent the forward movement of the paper, as it rises slightly when the paper is pulled forward, while the backward tendency of the paper causes it to bite the paper between the knife and the roller-9.

The roller 9 is provided with friction-bands 13, preferably of rubber, and which press the paper against the knife S. The object of these bands is to cause the movement ofthe paper when the roller is turned to project the edge of the paper beyond the knife to afford an easy finger-hold when a piece of paper is wanted, so that by simplyturning the roller the edge of the paper will shoot out between the roller and the knife. The roller 6o may be thus turned by simply rubbing the hand against it, or it may be turned by means of a pivoted plate, 14, provided with a dog or pawl, 15, engaging a ratchet-wheel, 16, rigidly secured to one of the journals of the roller 9, so that by-pressing the plate 14 inward from the position shown in full lines, Fig. II, to the position shown in dotted lines, same figure, the roller 9 will be turned and the edge of the paper made to project be-.7o yond the edge of t-he knife. The plate 14 is located directly beneath the roller, as shown,

so that the simple act of putting the fingers beneath the knife to take hold 'of the edge of the paper forces the plate inward, as described, and causes the edge of the paper to be exposed or brought beneath the edge of the knife.

Ve claim as our inventionl. In a paper-cutter, the combination of a So suitable support, knife, roll of paper, roller located close up against the knife, and a device for turning the roller to cause the paper to be moved by frictional contact between the roller and the knife, substantially as and S 5 for the purpose set forth.

2. In a paper-cutter, the combination of a suitable support, knife, a roll of paper, roller located close up against the knife, and a means for turning the roller, consisting of a 9o pivoted pla-te having ratchet-connection with the roller, substantially as and for the purpose set forth.

3. In a paper-cutter, the combination of a suitable support, a knife, a roll of paper, a roller located close up against the knife, means for turning the roller to move the paper forward, and a pivoted cam-bar over the roller to prevent the retrograde movement of the paper, substantially as and for the purroo pose set forth.
