ACI-I NES FOR CUTTING LEATHER, 80c.
Ju1y11,1876.
No.17 9,s45.
PETER A. OASSIDY, OF WASHINGTON, DISTRICT OF COLUMBIA.
IMPROVEMENT IN MACHINES FOR CUTTING LEATHER, &c.
Specification forming part of Letters Patent No. 179,645, dated July 11, 1876; application filed May 9, 1876.
To all whom it may concern:
Be it known that I, PETER A. OAssIDY, of
Washington, in the District of Golum bia, have invented a new and useful Machine for Outting Vellum -Oloth, Leather, Paper, or other similar articles into strips, which invention is fully set forth in the following specification, reference being bad to the accompanying drawin gs.
The object of my invention is to rapidly and cheaply cut into strips vellum-cloth for mending muster-rolls, documents, abstracts, leather for boolrbinding, harness making, &c., and paper, or any similar article.
To accomplish this I provide a cutter-holder or gage furnished with anumber of knives, operating upon and in combination with a bed upon which the article to be cut into strips is fastened, the bed having a number of parallel grooves to correspond with the cutters, and upon one side a guidepiece, upon which fits a groove in the cutter-holder, which so operates as to cause the cutters to move in a straight line, and to constantly retain their cutting-edges in the grooves.
in the accompanying drawing, Figurel is a perspective view of my machine, showing a piece of vellumeloth or other article to be cut fastened on the bed. Fig. 2 is a section of the cutterholder, showing the method of fastening the cutters.
The bed-piece A may be of any convenient length, havin gin its upper surface a number of parallel grooves,a b c d 0, made at such distances apart asitis desired that the width of the strips to be out should be. Upon one side of the bed-piece is a guide strip, K, over which fits a corresponding groove, f, at one side of the cutter-holder 1*. The cutter-holder F has secured therein the cutters A B C D E, which are placed at such a distance apart as to correspond with the grooves in which they move. The cutters are caused to movein. a straight line, and their cutting edges to remain constautly in the grooves, by the guidestrip K and the guide-groove f in the cutter-holder.
The cutter-holder is also provided with a handle, L, by which it may be grasped by the hand, and moved over the bed in the operation of cutting.
The cutters are made with two cuttingedges, ij, Fig. 2, so that they will cut, when moved over the bed, in either direction, and are also Wedge-shaped, and may thus be readily fastened into the holder by insertion into the tapering sockets, as shown in Fig. 3.
The bed-piece is furnished with pinsk l m, (shown in Fig. 1,) to'hold the material and keep the edges even and together when more than one thickness of cloth or other material is being cut.
The machine may have any convenient number of grooves and corresponding cutters, and they can be placed at any distance apart to correspond with the width of the strips to be cut.
In case the material to be cut is thin, like vellumeloth or paper, a number of thicknesses may be placed on the bed and cut at one time.
I claim as my invention- 1. In a machine for cutting vellum -cloth, leather, or other similar materials, the combination of a cutter-holder, F, carrying a number of knives, A B O D E, and having a guidegroove, f, with a bed, A, having grooves a b c d 6, corresponding with the cutters, a guidestrip, K, and holdingpins 76 l m, all to operate in the manner and for the purpose de scribed.
2. The cutters A B (J D E, having two cuttingedges, and wedge shaped in vertical cross-section, in combination with the cutterholder F, having tapering sockets, into which the wedge-shaped cutters fit, and a guidegroove, f, operating upon a bed, A, having grooves a, b c d 0, corresponding with cutters, guide-strip K, and holding-pins k l m, all to operate in the manner and for the purpose described.
