PAPER-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 326,916, dated September 22, 1885.

Application filed August 28, 1884.

T all whom, it may concern:

Be it known that I, LEONARD W. MoRsE, Jr., a citizen of the United States, residing at Mystic River, in the county of New London and State of Connecticut, have invented certain new and useful Improvements in Paper- Cutting Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has relation to paper-cutting machines, particularly that class operated by hand; and its object is to produce a machine of the class described adapted to meet the general wants of the trade; and to these ends the novelty consists in the construction of the mechanism for operating the cutter-knife, and the means for holding the paper while it is being cut, as hereinafter described and claimed.

In the accompanying drawings, the same letters of reference refer to the same parts of the invention.

Figure 1 is a front perspective view of the machine, showing the knife-operating mechanism; and Fig. 2 is a rear perspective showing the paper-clamping mechanism.

A A is the frame, having table B, top brace, C, and lower braces, D D, of the usual form.

E is the cutter-bar, hinged to the brackets c c by two pitnien, F F, and to the lower edge of said bar is secured the knife G.

H is a depending arm made integral with the cutter-bar E, and it is provided with two parallel bars, I I, the lower ends of which are secured to a short shaft, K, the outer ends of b which carry friction-rollers i 2', working in the slots L L in the cross-braces M M.

N N are toggle-joint levers, the one N secured at its lower end to the shaft K, and the upper end of the other, N, secured to the shaft 0 in the bearings 0, attached to the side of the frame A. The adjoining ends of this toggle are secured to a bolt or pin, P, in common with the upper end of a raclobar, R, which projects downward, and is kept in mesh with the segmental gear S by a friction-roller, s,

mounted on a shaft, 8, in the cross-bars M M. (Shown in dotted lines in Fig. l.)

The segmental gear S is mounted upon a shaft, T, passing through the cross-braces M M, and it is j ournaled in knee-brackets U U, secured to one side of the frame A, and its (No model.)

outer end is provided with a hand-lever, V, which operates the gear S.

From this construction it will be seen that when the hand-lever V is in a vertical position the rack-bar R is raised, which bows the toggle-levers, raises the parallel bars I I, and consequently lifts thekuifeblade. If, now, the lever V be pressed downward, the toggle-joint is straightened and the knife descends with a draw cut.

The mechanical arrangement is such that the paper is cut with the most economical expenditure of manual labor.

Fig. 4 indicates the clamping-bar, mounted so as to have free vertical play in the slots 5 and 6 in the frame A A, and it is raised and lowered by a screw, 7, having an operatinghandle, 8.

9 and 10 are arms secured to the rear of the frame A A, and in these arms is journaled a shaft, 12, rigidly secured to which are two levers, 13 14, the opposite ends of which are hinged to shoes 15 16, secured to the rear side of the clamping-bar H. The object of this construction is to cause the clamping-bar to descend in a parallel plane with the table, and thus hold the paper while being cut uniformly and evenly along its entire length, and at the same time clamp shorter widths of paper with equal facility, as it will be observed that should a lot of paper only a few inches in width be required to be cut, it may be placed either in the center of the clampingbar or under either end, and when the screw 7 is operated, should there be any tendency of one end of the clampingbar to descend before the other, this motion is communicated to the lever at that end, thence through the medium of the shaft 12 to the other lever and to the other end of the said bar, so that it will be seen that it is impossible for the bar to descend unevenly.

Having thus described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, is-

1. The cutter-bar E, provided with the parallel bars I I, having their lower ends secured to the shaft K, working upon rollers in the slots L L, in combination with the toggle N N, rack-bar It, segmental gear S, and lever V, as and for the purpose set forth.
