COMPOUND TOOL.

SPECIFICATION forming part of Letters Patent No. 333,830, dated January 5, 1886.

Application filed September 1, 1885. Serial No. 175,891. (No model.)

To aZZ whom it may concern:

Be it known that 1, JOHN OONLEY, a citizen of the United States, residing; at Pullman, in the county of Cook, State of Illinois, have invented a certain new and useful Improvement in Compound Tools, of which the following is a specification.

This invention relates more particularly to an improvement in tools of that class wherein the tool comprises a pair of levers pivoted to provide jaws that are equipped with cuttingblades, the said levers being further provided with laterally-extending jaws adjacent to the pivotal point, and arranged so as to furnish at one side of the tool a pair of jaws that may serve as a punch, and at the opposite side a pair ofjaws that may serve as nippers.

The object of my improvement is to adjustably seat and secure the cutting-blades in a novel and efficient way, whereby the blades can be firmly held, and, when desired, uniformly and evenly advanced to take up wear, thereby increasing the general eficiency of the tool.

To such end my invention consists in the matters hereinafter described,and particularly pointed out in the claim.

In the drawings, Figure 1 is a perspective View of an implement embodying my invention. Fig. 2 is a side view thereof, on a slightly larger scale, with certain parts in section to more clearly illustrate details.

The two levers A and B are arranged to cross each other at a point intermediate of their ends, similar to the levers of a pair of shears, and are at their point of crossing pivotally connected together by a pivot, G, which serves as a fulcrum about which the two levers operate. These levers are curved and otherwise properly shaped at one side of the fulcrum to provide a pair of jaws, A and B, and at their opposite end portions are appropriately bent to provide the two handles A and B in which way each lever has one end adapted to serve as one of the pair of handles, and its opposite end adapted to serve as one of the jaws provided for the cuttingblades D, which are secured to the jaws A and B, respectively. The handles, and consequently the jaws carrying the blades, are normally held apart by a spring, E, of any desired construction, arranged between the handles, in which way the blades, which are at all times ready for operation, can be closed together by grasping the handles of the implement and drawing them together against the resistance of the spring. The levers are mortised or recessed along their opposing sides at their point of crossing, so as to bring the jaws and handles in substantially one and the same plane of action, as will be readily understood. The lever A is provided with two projections, A and A, respectively located at opposite sides of the pivot, and the lever B is provided with similar projections, 13 and 13*, likewise arranged at opposite sides of the pivot. These several projections upon the two levers are arranged so as to provide two pairs of jaws situated intermediate of the handles and the cutting jaws, and operative, respectively, at opposite sides ofthe pivot. One of the two jaws A? and B is provided with a punch, F, and the remaining one thereof is provided with a bed, F, whereon the material to be punched is pressed by the punch during the act of cutting through the same. This bed is desirably made of brass,or of some metal suited to the purpose for which it is intended, and is preferably formed by a bushing or plug arranged to screw into its allotted jaw, so that it can be adjusted therein as may be required. The jaws A and B are plane-faced, or may have serrated faces, if preferred, and serve as clamping or gripping jaws, which may be employed for heading up rivets-such, for instance, as shall have been placed in the holes previously cut by the punch. These jaws will also be found serviceable for other purposesas, for example, they can be used as an ordinary pair of nippers. One of the jaws A and B is provided at its outer end with a socket, g, suitable for securing and holding a prong or awl, G, which latter may be round or angular in cross-section.

This pointed instrument may be used for various purposes while held by the jaw, and should occasion require it can be taken out and used, for instance, to clean out the punch. Each one of the jaws A and B has one of its flattened sides provided with a shallow rectangular recess, extending from the inner longitudinal edge of the jaw back to within a short distance from the outer or back edge of the jaw, and forming a seat for holding one of the blades D. The blades are adapted to fit these shallow recesses or seats and have their cutting-edges extended somewhat beyond the inner edges of the jaws, so as to properly present said cuttingedges to the article to be cut. Each blade is held in its allotted seat by means of one or more, but desirably two, set-screws,

H, arranged to pass through slots D, formed transversely through the blade. These setscrews screw into the body of the jaw, in which Way, by loosening up the set-screws, the blades can be set forward toan extent proportional to the extent of wear along their cutting-edges.

As a means for adjusting the blades forward each jaw carries one or more, but preferably two, screws, I, arranged to Work through threaded holes formed through the back wall of the recesses wherein the blades are held, so that the inner ends of the set-screws shall abut against the back edges of the blades. Preferably the jaws have their back portions forming the rear walls of their shallow seats or recesses slightly widened at the points a, as herein shown on jaw B, where the screws I have their bearing, it being understood that the jaw A is recessed and otherwise formed similar to B.

The foregoing arrangement involves a desirable means for holding and adjusting the and by the screws passing through their slots. 40

Vhat I claim as my invention is- A tool, substantially for the purpose described, provided with the two levers pivoted and constructed to form the recessed jaws A and B, combined with the blades D, adjustably seated and held in the recesses of said jaws, the screws H, passing through the slots formed transversely through the said jaws, and the screws I, applied to the jaws and abutting against the rear edges of the blades, substantially as shown and described, and for the purpose set forth.

In witness whereof I have hereto signed my name in the presence of two subscribing wit- LIGSSGS.
