CUTTING- MACHINE.

SPEGIFIOATION forming part of Letters Patent No. 601,868, dated April 5, 1898.

Application filed March 1 1397- To aZZ- whom it may concern:

Be it known that I, DAVID'BROOKS, a citizen of the United States, residing at Verona, in the county of Essex and State of New J ersey, have invented certain new and useful Improvements in Cutting-Machines for Tampico, Leather, 850. and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The objects of this invention are to facilitate and render more easy the operation of cutting tampieo, hair, leather, and other fibrous or other material, and especially for service in cutting fibers for brushes, brooms, and the like, to secure a more perfect and uniform cutting, to perform the cutting operation at a reduced expense of labor, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of theworking parts.

The invention consists in the improved cut ting-machine and in the arrangements and combinations of parts thereof, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referringto the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the views, Figure 1 is a front elevation of the improved cutting-machine and Fig. 2 is a vertical section of the same, taken on line at.

In said drawings, (1, indicates a suitable bench or table, at the top of which is formed a narrow casing or inclosure b to protect certain operating parts. At the back, below the top-board, is a support 0, suitably secured to the framework of the bench. Said support is preferably of wood and extends above the top of the top board or bench and forms a portion of the box or inclosure b, above referred to. To the said bench, at any suitable point therein, is fulcrumed, as at. d, a pedal or foot-lever c, to which is pivoted, at a point between the fulcrum and free end, a connecting-rodf, which extends upward into pivotal engagement with a lever g, fulcrumed beneath the top board on the bearing h. The

Serial No. 628,649. (No model.)

said lever g has at its end opposite its fulcrumal bearing a pivotal connection with a cutting-blade i, which latter extends upward from said lever through an opening in the top of the bench and engages a second longer leverj, having its fulcrum within the box or case b at the back, as at k.

By having the lever j longer than the lower lever g the cutter is, as it is drawn down by the pedal 6 and connections, given a'to-andfro movement, as well as an up-and-down movement, and passes out through a slot in the casing or box E) into engagement with the bunches of fiber or other matter to be cut, engaging thesame with a shearing action by which the cutting is rendered easy and effective.

Upon the top of the bench or table I provide upwardly-extending cutter-blocks Z Z, having an opening between, as at m, Fig. 1, into which the cutting-blade enters when it has about terminated its downward-and-forward cutting movement. Said cutter-blocks form one side of a trough or receptacle open at the top, into which the bundles of fiber or other material to be out can be freely laid from above, the cutting-blade forming the other side of said trough or receptacle. To secure a return movement of the cutter-blade automatically, 1 have provided a strong spring we, secured at the back of the bench, as at 'n, and consisting of a resilient piece of wood or metal. At the top or free end of said spring it is pivotally joined to a connecting-rod 0, which extends forward from said spring, through a slot in the box, into pivotal relation to the lever j, so as to draw the said lever j and knife connected therewith backward when the foot is removed from the pedal.

The lever g, beneath the top board of the machine, may be suitably incased and is provided with a guide or guides 19, adapted to prevent the said lever g from moving laterally from its proper vertical relation to the cooperating parts.

In operating the machine the person in charge simply takes a bunch of fibers or other material and inserts it between the cutter-blocks b and the forward edges of the cutter-blade i. The foot is then placed upon the pedal e and is pressed downward, producing a forward-and-downward movement of the cutter-blade and effects the shearing action by which the bunch of fibers are cut with smoothness.

Having thus described the invention, what I claim as new is-- 1. The improved cutting-machine herein described, comprising a bench or table having cutting-blocks afiiXed to the upper surface thereof and projecting upward, a cutting-blade working in an open slot in the top of said table, and having an upwind-down movement and a movement to and from said blocks, said cutting-blade when in normal position forming with the blocks, the sides of a trough-like aperture into which the bunch of fibers to be out can be dropped from above, and long and short levers at the op- December, 1896.
