lIMPROVEMENT IN PAPER-CUTTING MACHINES.

Specification forming part of Letters Patent No. 149,690, dated April 14,1874; application tiled February 21, 1873.

To all whom it may concern:

Be it known that I, 'SAMUEL W. SoULE, of the city, county, and State of New York, have invented, made,and applied to use a new and usefulMachine for Cutting Paper; and that the following is a full, clear, and correct description of the same, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, in which- Figure I is a front view of my paper-cutting machine, the front table being removed and the knifebeing in position to commence work. Fig. II is a front view of the same, the knife being shown in position after working. Fig. III is a transversesection of my paper-cutter.

In the drawings, like parts of the invention are pointed out 'by the same letters of reference.

The nature of the present invention relates to improvements, as more fully hereinafter set forth, in the construction of a paper-cutting machine, and will be found to relate more particularly to the .means employed to operate the knife.

To enable those skilled in the arts to make and use my invention, I will describe the same.

A shows a frame for supporting the operative parts of the machine,and B is a table, upon which the paper to be cut is placed. Held in the frame A is one endof the shaft G, having secured upon it a cog-wheel, D, and attached to it a lever or handle, E 5 or, in lieu of the lever, suitable gearing for other than hand-power. Upon the opposite side of the frame A is a roller, F, free to revolve upon its axis. Upon this spindle, also, is held one end of guide-bar Gr, the opposite end of the same being held upon'a stud inserted in the upright portion of the frame A. H shows the knifebar supporting the knife I. This knife-bar has gearing J attached to one end of its inclined bottom edge, in direct line with its motion, while the opposite end is inclined in like direction, sokthat when placedl in position in the machine the gearing J shall engage with the cog-wheel D, and the opposite inclined end shall rest upon the roller F. K shows the front table of the machine, made movable for the purpose of clearing the table from the knife and knife-bar, and supported by the brackets L and L2, one of which is provided with a steady -jpin entering int-o the frame A, and the bracket L2 being provided with openings, so that they may be passed over a rod, M, projecting from the frame A. Passed over this rod M, and confined between the rear bracket L2 and a collar, N, held upon the rod M by a set-screw, a, is a spiral spring,-O. The clamping device by which the paper to be cut is secured consists of a plate, P, and plate It,

connected by the side rods Q. The plate It is provided, about centrally, with an opening having a female screw-thread cut within the same, with which the male screw S engages.

A hand-wheel, 24, is secured upon the end of this male screw S, and between the cross-bars P and R, and the upper end of the male screw S is free to-revolve in abracket, T, secured upon the under side of the frame A. To the front of the cross-bar P is held a plate, U,`a screw, V, passing through thissecondary plate, and having a spiral spring, W, passing over it, and having its bearing upon the face of the secondary plate U and the head of the screw V. Pins b inserted in the top plate P, and entering openings in the secondary plate, steady and guide the same as it moves, as described hereinafter. machine. This consists of a plain plate of metal, made true upon its face and bottom edge,

secured upon the rody Y, which rod is free to move in openings in the upright portion of the frame A and the standard Z. A set-screw, c, inserted in the upright, is used to hold the paper-gage in any desired position.

Such being the construction, the operation is as follows: The knife-bar and knife are placed in position in the machine, the gearing upon one end of the knife-bar engaging with the cog-wheel, and the opposite inclined end resting upon the roller. chine is placed in the proper position by moving the rod Y, to which Ait is attached, either backward or forward, as may be required, and fastening the same in position by tightening the set-screw c. They paper is now'placed upon the table B of the machine, and the hand of the operator being placed upon the clampwheel 24, and the same being turned, the rod s, entering into and engaging with the screwthreaded opening in the plate It, causes the .fr shows the papergage of the The gage of the ma- A clamp to be drawn down. As already described, the rods Q, which support the crossbar P, are attached to the cross-bary R, and, as the same is drawn down, the top plate is drawn down upon the paper, confining the same between the table and itself. The paper is now in proper position to be cut. By grasping lever or handle E upon the shaft G and turning the same, the cog-wheel engages with the gearing J upon the knife-bar H, and elevates the same, giving to the knife I a lateral movement through the paper, the opposite end of the knife-bar rising upon the-roller F, and being guided by the guide-bar G. As the knife passes throughl the paper the front table K `yields to correspond with the increased thickness of the knife and bar, and clears the paper cut off from the bar. As the same is thrown forward the spiral spring O, held upon the rod M, between the bracket L2 and the collar N, is compressed, and after the knife passes through the paper, the plate U, attached to the plate P, as described, yields to the knife, and is thrown forward, compressing the spiral spring W between itself and the screw V. The paper having been cut by this lateral movement of the knife, the lever or handle E is turned in the contrary direction, and, the cog-wheel D engaging with the gearing J upon the knife-bar H, the knife and knifebar are drawn down to their proper position. As the knife descends, the spiral spring W is expanded, and returns the secondary plate to its former position, and the spiral spring O is expanded, and restores the table K to its former position.

The lever E can be pla-ced in any desired position before cutting by, raising the end of the knife-bar out of gear with the pinion, and, having turned the lever in the desired position, restoring the knife-bar. When the knifebar recedes, it is arrested at its farthest extreme-by the rod M, which is necessary in cutting paper on the table B but when paper is cut by a pattern, then the knife is to be arrested by the levers striking a stop.

The knife-bar can be placed in any desired position by resting the lever against a stop, and raising the bar out of gear and pushing it up or down, as desired.

Having now set forth my invention, what I claim as new isl. The yielding table K, substantially as and for the purpose specified.

2. The combination of the yielding table K, knife-bar H, knife I, roller F, gearing J, shaft C, and cog-wheel D, as and for the purposes specified.

3. The combination of the cross-bars I? and R, side rods Q, hand-wheel 24, and yielding plate U, as and for the purposes set forth.

4. The combination ofthe gage a', rod Y, and set-screw c, the rod sliding longitudinally, and capable of being partially rotated, so that the gage may be moved along the table and turned off of and away from the table, for the purposes set forth.
