ROD-CUTTER.

SPECIFICATION forming part of Letters Patent No. 464,976, dated December 15, 1891.

Application filed April 18, 1891. Serial No. 389.413. (No model.)

To all whom it mag concern.-

Be it known that I, ERICK M. LINDFORS, a citizen of the United States, and a resident of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Rod-Cutters, of which I do hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in rod-cutters; and its objects are to provide a cutter which shall divide a bar of metal with a square cut and without drawing or leaving a ragged edge upon its extremity, and with increased power of action.

My invention consists of the hereindescribed tool and in the combination,arrangement, and construction of the various parts, as hereinafter described, shown in the drawings, and more specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of the complete device designed for hand-power. Fig. 2 is a vertical section on line X X, Fig. 1. Fig. 3 is a side elevation of ratchet and lever device for Working the tool.

A in the drawings represents a substantial bed of cast metal, the front of which is faced down at Af to leave avertical bearing-surface for the circular cutting-disk B. Bearings a a are also left in the bed A, upon which thedisk B revolves, waste oil or other matter being carried oif in the trough a. The disk B is secured against the face A by the ring 0, which is fastened securely to the casting A by screws 0 c c, and both faces of the disk 0 are carefully faced to correspond with its bearing 0 0 against the casting and ring. The periphery of the disk 0 is provided with worm-wheel gear at O, which engage with the worm D, mounted upon bearings A on the casting A. The worm-shaft D is continued outward from the machine and is provided, preferably, with a fiy-wheel E to give force to the revolution of the worm and a handle F or crank by which to operate it.

The bed or casting A is seen to be pierced with apertures of the different sizes of rod for which the machine is adapted, as at A and the disk 0 is correspondinglypierced, as at C In operation, when itis desired to cut a bar of metal, it is inserted into the aperture of corresponding size in the casting, and the wheel is turned until the similar aperture in the disk C coincides with it, when it is pushed through as far as desired. By continuing the movement of the wheel the baris cut across squarely and finished at once.

A stop, as G, may be employed to secure the proper length of out, and is adjustable upon the slotted extension A of the bed A by the screw g'.

N and O are hardened thimbles inserted in the apertures A and B When a greater power is required than can be obtained by using the wheel, the additional ratchet integral with the main shaft H is employed to operate the worm in connection with the lever I, pivotedupon the shaft. A dog J, attached to the lever I, engages the teeth h of the ratchet. Aspring K serves to keep the dog in engagement, and the springactuated pin secures the ratchet out of engagement when the lever is not in use. A pin L in the casting and circular slot Min the disk 0 seem to stop the machine when turned backward at the proper point to exactly register the openings in the disk and casting, respectively, opposite one another, so that the rods can be introduced for cutting.

The advantages of this form of tool will be obvious to mechanics such as blacksmiths or tool-makers, since rods can be out therewith with perfectly-finished and accuratelysquared ends such as cannot be made by common shears or well-known machinery.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a rod-cutter, a suitably-pierced disk provided with a worn1-gear upon its periph-. cry, in combination with a main bearing or stand provided with an extension faced to correspond with the inner face of the said disk and pierced with apertures adapted to register with the apertures in the disk, with worm-gear engaging the disk and mounted upon said extension of the frame, substantially as and in the manner set forth.

2. In a cutter, a main frame A, a disk 0, mounted upon said frame in close contact with an extended portion thereof, apertures in the disk and frame registering with one another, a ring securing the said disk and frame together by means of clamping-screws, Worm-gear engaging with the periphery of the disk, and a pin in one of the adjacent surfaces and slot in the other, substantially as and for the purpose specified.

3. In a cutter,a disk provided With a wormgear on its periphery,a main stand provided with an extension having a plain surface adjacent to the inner face of the disk, perforations extending through the disk and frame, hardened thimbles inserted in the apertures, a ring with screws covering the extension bearing-edges of the disk and frame, and a shaft and worm Wheel mounted upon the frame, the said worm engaging the periphery of the disk, substantially as described.

4. In a hand rod-butter, a main frame, a disk mounted in said frame, a plain surface of the frame engaging one of the faces of the disk, registering perforations through the disk and frame, a worm and shaft mounted upon the frame, said worm engaging a gear-wheel upon the periphery of the disk, and means for revolving the shaft by hand, substantially as described.

5. In acutter,a main frame and disk mounted thereon, perforations passing through the disk and frame, a Worm upon the frame and gear upon the disk, and stop I, substantially as described.
