PAPER-CUTTER.

SPECIFICATION forming part of Letters Patent No. 628,908, dated July 11, 1899.

Application filed March 18,1899. serial No. 709.628. (N model.)

To all whom it may concern: paratus, supported upon laterally-extending Be it known that I, \VILLIAM I-l. LEWIS, a parts of the frame, and between them there citizen of the United States, and a resident of is a bottom board E inserted, (there being side lluntington,in the county of Suffolk and State boards E likewise provided,) so that a box or 5 of New York, have invented a new and Imlike receptacle is formed beneath the cutter,

F F are two upwardly-curved arms, which The special features of this invention are are attached to each side of the board A,as the arrangement of the parts in such manner shown, and G G are the ends of a cross-shaft, that a shearing cut is secured; also, there is to which the swinging cutter-blade H is at no upward lifting by the hand of the operator tached by screws I or otherwise, as preferred, l 15 of the lever which actuates the cutter, which and this blade H is curved longitudinally, as

The board A is hinged The operation of the apparatus as thus far 50 at (J to a leg or stanchion D, there being andescribed is as follows: A suitable stop N other stanchion D at the front end of the ap- (see Fig. '7) is provided at some appropriate point to prevent the swinging blade from tip such that the extreme left-hand end of the swinging blade will rest against the front edge of the stationary blade B. It will be noted that the springs L L when the parts are in this position will pull the swinging blade into contact with the stationary blade and that this action continues during the entire time that pressure is applied to the lever N, whereby the blade is rocked upon its trunnions G and is caused to sweep across the edge of the stationary blade by a proper shearing action, and that the moment pressure upon the lever N is removed the springs automatically return the swinging blade to its initial position; and it will be especially observed that inasmuch as the springs are permanent in their action there will continue to be a grinding effect exerted by one blade upon the other, whereby it has been found that they rather increase in sharpness than otherwise, and that there will never arise an occasion when the contact between the two blades is not sufficiently intimate to properly sever the web or strip of material between them. It will also be noted that since the swinging blade 11 is automatically returned to its initial position there is no lifting action required upon the lever N, and therefore no necessity for providing means for holding the devices immovable upon the table or other support.

In Figs. 3 and 4 I show a construction which is in many respects identical with that just described, and the operation is likewise practically identical. I do not letter the parts excepting those wherein a difference appears. In this construction the swinging blade at instead of being curved to effect the shearing action is made perfectly straight, the shearing action being secured by locating the trunnions one on one side and the other 011 the other side of the blade, so that it is supported diagonally across the edge of the stationary blade. In this way the same shearing action is attained. One of the trunnions (shown at 1)) consists of the end of a steel or equivalent bar I), which is fastened by rivets or otherwise to the upper side of the blade at, and c, the opposite trunnion, is the projecting end of a similar bar 0, attached by rivets to the under side of this same blade, so that the plane of the two trunnions is separated by a distance equal to the thickness of the blade. In this form also I embody a modification relative to the box or drawer for containing the clippings. It is as follows: d is a stationary leg or support projecting downwardly from the rear end of the superposed board, which I mark A, the same as before. 2 is a horizontally-extending bar projecting forwardly from the brace d, there being one on each side of the apparatus. f f f represent a drawer adapted to be pulled forwardly, sliding upon the side bars 6 e, there being a dovetail or similar connection between the sides of the. drawer and the bars 6, as shown in Fig. 5. This is sometimes convenient, because then all the parts of the paper or other web which project forwardly through the blades will be caught in the drawer and prevented from displacement when severed. The operation of this modified constructionis the same as that just described, and no further remark need be made.

It will be obvious to those who are familiar with this art that certain modifications may be made in the construction of the parts coinposing my invention. I therefore do not limit myself to the details, excepting as they may be hereinafter claimed. Having described my invention, I claim 1. In a cutting device the combination of a fixed blade, a swinging blade pivoted in elongated bearings, and springs to maintain the engagement lbetween the two blades, for the purposes set forth.

2. In a cutting device, the combination of a fixed blade, a swinging blade pivoted in elongated bearings, depending arms connected with the swinging blade and springs connected with said arms to maintain the engagement between the two blades, for the purposes set forth.

3. In a cutting device the combination of a fixed blade, a swinging blade pivoted in elongated bearings, the trunnions for the swinging blade beinglocated on opposite sides of it, and springs to maintain the engagement between the two blades, for the purposes set forth.

Signed at New York, in the county of New York' and State of New York, this 16th day of March, 1899.

WILLIAM H. LEWIS.
