PAPER-CUTTER.

SPECIFICATION forming part of Letters Patent No. 393,629, dated November 2'7l 1888.

Application filed Api-i128, 1888, Serial No. 271,505.

To all whom it may concern:

Beit known that I, LEo EHRLIcI-r, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Im provcment in Paper-Cutters, of which the 'fol lowing is a full, clear, and exact description,v

reference being had to the accompanying draw ings, forming partof this specification, and in which- Figure I is a front elevation. Fig. II is an end View. Fig. III is an cnd view showing a modification. Figs. IV to IX, inclusive, are enlarged sections and detail views illustrating different parts.

My'invcntion relates to an improvement in paper-cutters; and my invention consists in features of novely hereinafter fully described, andpointed out in the claims.

Referring to the drawings, 1 represents a suitable base, to which ends 2 are secured.

3 represents the roller jonrnaled in the ends and upon which the paper 4 is wound.

5 represents arms secured to a cross-piece, G, by means of boxes 7, and which are con nected to the cross-piece by means of springs 8, which act to press a rod or bar on the lower ends of the arms against the roll of paper.

9 represents the rod secured to the lower ends of the-arms 5, and which is held against the roll of paper, as stated, by means of the Secured to the ends of this rod 9 are blocks 10, to vone of which a roller, I2, is secured by means of a bracket, 13, (see Fig. VI.) held upon the block by means of the knife-bar,which has collars 11i. The other end of the roller is connected to the other block, 10, by means of a square nut, 15, (see Fig. VIIL) fitting in the block, and held therein by a plate, 16, pivoted to this block at 17.

Secured to the blocks is a knife composed of a square bar, 20, having end pieces, 2l, by which itis secured to the blocks. The paper passes in between the bar 9 and the roller l2, as shown in Figs. IV and V, its end projecting,as shown at 22. Vheu a piece of paper is wanted, it is drawn out and cut off against the knife, as shown in Fig. I.

On the roller 12 is an eccentric, 27, near the middle of the roller, and which presses (No model.)

the paper against the rod 9 and prevents the backward turning of the paper roll. On the roller is also a weight, 23, which acts to force the part 27 against the rod 9. When the end of the paper is to be inserted between the rods 9 and 12, the free end of the roller l2 is dropped down, as shown by dotted lines, Fig. I, by swinging the catch-plate 16 outward into the position shown by dotted lines, Fig. IX.

The rod 9 may be supported on different arms to those upon which the roller 121s supported, as shown in the modification, Fig. III.

I reserve the right to claim in another application, Serial No. 271,507, filed April 23, 1888, a construction whereby one of the rods can be swung away from the other by mounting the rodson different arms.

I claim as my invention- 1. In a paper-cutter, the combination of, the ends, roller journaled in the ends,springarm s, rod secured to the springarms, block secured to the rod, a rod secured in the blocks, and knife, substantially as and for the purpose set forth.

2. In a paper-cutter, the combination of the ends, roller jonrnaled in the ends,spring-arms, rod 9, secured to the spring-arms, a rod pivotcd at one end tothe rod 9 and secured to the rod 9 at the other end by means of a suitable catch, and knife secured to the rod 9, substantially as and for the purpose set forth.

3. In a paper-cutter, the combination of the ends, roller journaled in the ends, springarms 5, rod 9, secured to the spring-arms, blocks secured tothe rod 9,a rod secured in the blocks, and eccentric on the rod, substantially as and for the purpose set forth;
