CLOTH-CUTTING MACHINE.

Specification of Letters Patent.

Patented March 12, 1907.

Application filed January 3, 1905. Renewed August 14,1906. Serial No, 330.587.

. of my invention is to provide certain improvements whereby the operation of the machine is rendered easier, and another object of the invention is to provide a sharpener in connection with the cutting mechanism by means of which said cutting mechanism can be sharpened whenever desired.

With these objects in view the invention consists in' the novel features of construction and arrangement, all of which will be fully described hereinafter, and pointed out in the claims.

In the drawings forming a part of this specification, Figure l is a side elevation of a cloth-cutting machine constructed in ac cordance with my invention. Fig. 2 is a front view of the same. F 3 is a vertical longitudinal section. Fig. 4 is a horizontal section on the line 4 4 of Fig. 3. Fig. 5 is a sectional plan on the line 5 5 of Fig. 3. 6 is an inverted plan view of the base.

In carrying out my invention I employ a base A, which is preferably made solid and is provided with suitable rollers A, so that said base can be easily rolled or moved. Connected to this base A, preferably at a point to the rear of the center of said base, is a casing B, in which moves the endless cutter (1, comprising a series of cutting-blades 0 alternating with the connecting-links C said endless cutter passing around a sprocket D at the upper end and a smooth ball-bearing idler-pulley E at the lower end. The casing B is preferably made in two sections, and the central portion between the sprocket D and pulley E is made with a guide portion F, carrying guide-ribs F which engage the grooved links and cutting-blades and hold the said blades in perfect alinement. This guide por tion F may be integral with one of the sections of the casing, thereby providing two runways G and G, through whi ch the endless cutter moves, the runway G being opened 1 preferably Figj at the forward side, through which the cutting edges of the blades C project. An electric motor H 1s mounted upon a bracket H connected to the casing B, the armature of said motor being arranged upon the shaft D of the drive-sprocket D, so that by rotating the said sprocket the endless chain of cutters will'be operated, said chain moving in the direction indicated by the arrow in Fig. 3. By having the casing B arranged at a point to the rear of the base and by having the forward portion of said base made gradually sloping, as indicated at A the cloth to be cut will move easily to the cutter.

I indicates a slotted guide-plate attached to the base and through which the cuttingblades pass as they cut the cloth. This slotted guide-plate I is preferably formed integral with the plate 1, which serves as a means for connecting the casing B to the base A, as most clearly shown in Fig. 5. The base is recessed, as shown at A in order to provide ample space for the operation of the guides.

K indicates a handle connected to the easing B, by means of which the machine is moved as required.

L indicates a pair of sharpening-blocks, preferably of emery, said blocks being con nected to the outer ends of a bifurcated lever M, pivoted at M to a base M carried by the handle K, and a spring M bearing upon the under side of the handle of the lever, holds the lever and sharpening-blocks in their nor mal positions, each member of the bifurcated lever being hinged, as shown at M and said hinged members rest upon a rest-pin M when the said parts are in their normal positions. WVhen, however, it is desired to sharpen the cutter, the handle of the lever M is pressed down, and the members being hinged, as shown at M*, the cuttingblocks are thrown downwardly into engagement with the cutting edges of the knives, the outer sections of the lever members being pivoted at M. The endless chain of cutterblades will of course be operated by the motor during the sharpening operation, and

when the sharpening operation has been completed the lever is released, and the spring M will immediately return all ihe parts to their normal positions, and the cut ting operation can then be carried on.

It will thus be seen that I provide an we as shown at G, and

ceedingly simple, durable, and highly eflicient construction of cloth-cutting machine of the character described.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is

1.. In a cloth-cutting machine in combination with the base, of the casing connected thereto, said casing being opened at the front, the guide-plate arranged upon the base at the forward side of the casing, the driving sprocket and pulley arranged Within the cas .ing and the central guiding portion carrying the guide-ribs, the operating-handle attached to the casing, a lever pivoted to a base carried by the handle provided With sharpeningblocks and means carried by said casing for driving the sprocket as set forth.

2. In a cloth-cutting machine in combina- 20 tion With the base, casing, endless chain of cutting-blades, and means for guiding and operating said endless chain of cutters, of the operating-handle, the bifurcated lever pivotally mounted upon the said handle, the members of said lever being made in sections hinged together, the outer sections being pivoted to the casing, and the sharpeningblocks carried at the outer ends of said outer members and adapted to be brought into engagement With the cutting-blades When the handle of the lever is pressed downwardly, the rest-pins for supporting the-joint of the members of the lever and the spring for returning the lever and sharpening-blocks to their normal positions, as set forth.
