UNITED STATES PATENT OFFICE.

FREDERICK W. DROS'IEN,

on ST. LOUIS, MISSOURI.

PAPER-CUTTER.

SPECIFICATION forming part of Letters Patent No. 365,334, dated June 21, I887.

Application filed April 5, 1887. Serial Nofesrmm.

To all whom it may concern.-

Be it known that I, FREDERICK W. DROS- TEN, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Paper Gutters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this speci-- fieation, and in which Figure I represents a perspective view of myimproved paper-cutter. Fig. II is a transverse section through the roll and knife, showing part of the frame in elevation. Fig. III is a detail side elevation, illustratinga modifieation of the form shown in Fig. I; and Fig. IV is an end view, showing still another modification.

My invention relates to an improvedpapercutter for store use and the like; and my in vention consists in features of novelty hereinafter 'fully described, and pointed out in the claims.

Referring to the drawings, 1 represents the frame, provided with feet 2, by which it may be secured to any suitable support, and which 'is tied together by a rod, 3, at bottom, and a strip, 4, at top.

5 represents a roller, provided with gudgeons 6, fitting in slots or notches 7 of the frame, and upon this roller is wound the paper 8, which is removed as required for use.

9 represents aknife secured to a sliding heador plate, 10, held and working in slots 11 of the frame 1, and provided with projections 12, by which it is kept from end movement in the frame. Theknife projects downwardly and forwardly -from the head 10, as shown in Figs. I and II.

13 represents a spring (a leaf-spring being preferred) located between the head 10 and the strip 4 of the frame, and which serves to hold the knife down upon the roll, and which also serves to feed the knife down antomatically as the roll is reduced in size. \Vhen a piece of paper is wanted, the roll is pulled out, as shown in Fig. II, and then cut off by drawing it against the edge of the knife. 1

As a modification of the spring shown in Fig. I, coil-springs 15 may be used, as shown in Fig. III, the springs being'connected to a: to

lugs or extensions 16 of the head 10, and to pins 17 on the frame. These springs, it will be'seen, will hold the knife down upon the roll of paper.

(No model.)

In Fig. IV is shown still another modification, where a spring is not used at all, but where the end is accomplished by making the slots 11 inclined, so that while the knife and cross-head are allowed to feed down automatically they will not be lifted by the strain of the paper upon the knife, for the reason that the slots 11 are inclined, causing the cr'os'shead to twist and bind in the slots when pressure is brought on the eutting-edge of the knife, thereby producing so much friction that the knife will not be raised by the pressure of the paper upon it as the latter is being cut off.

When it is desired to remove the roller to substitute it by another, the crosshead and knife are raised until the roller can be removed from the inclined slots 11, as will be plainly understood.

If preferred, in the modification shown in Fig. IV the knife may be provided with a spring.

I claim as my invention- 1. In a'paper-cutter, the combinatiomwith a roller and with the frame having slots, and having notches in which said roller is removablyjournaled, of a cross-head whose ends engage in said slots, and whichcross-head is guided thereby, and a knife secured to said cross-head and caused to maintain a constant pressure upon the roller as its size decreases by means of a spring, substantially as set forth.

2. In a paper'cutter, the combination, with the roller, of a vertical frame having notches for the journals of said roller, and inclined slots, and a knife resting on said roller and guided by said inclined slots, whereby the gravitation of the knife is permitted while its opposite motion is resisted, substantially as set forth.

7 3. In apa-per-cutter, the combinationof the frame having slots 11 and notches, roller having gudgeons fitting in the notches in the frame, cross-head having lugs 12 and fitting in the slots of the frame, knife projecting forwardly and downwardly and secured to the cross-head, and spring located between the cr0ss-head and thetop of the frame, substantially as set forth.
