UNITED STATES PATENT OFFICE.
IMPROVEMENT IN BLACKSMITHS HARDIES.
Specification forming part of Letters Patent No. 117,665, dated August 1, 1871.
To all whom it may concern:
Be it known that I, CHARLES F. MOORE, of Snedikerville, in the county of Bradford and State of Pennsylvania, have invented a certain Improvement in Blacksmiths Hardy; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawing making part of this specification, in which- Figure 1 is a side elevation of my improved hardy. Fig. 2 is a perspective view of the oscillating upper jaw detached.
The same letters of reference are used in both iigures in the designation of identical parts.
This invention relates to a blacksmiths tool, termed a hardy; and my improvement consists in a novel construction of such an instrument,
W to be hereinafter generally explained and specilically pointed out in the claim.
TheA lower jaw A ofthe tool forms part of a frame, consisting of a horizontal bar, A1, and a vertical bar, A2. The horizontal bar A1 is constructed with a downwardly-projecting shank, A3, iitting the usual aperture in an anvil, and forming a continuation of the jaw A. The latter should be made of steel and hardened, and terminate in a cutting-edge, as shown. The arm or shank B1 of the upper oscillating` jaw B is pivoted upon a bolt, b, in the forked upper end of the vertical bar A2 of the frame, and is made of such length that on pressing it down to close the jaws the edge of the upper one will just pass that of the lower one. The jaw B is also made of hardened steel, and is extended beyond the width of its arm to form a hammer-head, upon which the blows are struck in cutting pieces of metal between the jaws. The shank or arm Bl is thrown up to open the jaws by means of a spring, O, which is fastened to the inner side of the vertical bar of the frame, bearing with its free end against a shoulder formed on the arm B1, by reducing the part B2, by which it is pivoted to the frame. This reduced part B2 is conf structed with a downwardly curved stop, b', which limits the action of the spring by coming in contact with the outer side of the vertical bar A2 of the frame when the jaws have been opened a suiicient distance. All the parts of the tool, with the exception of the jaws and spring, are preferably made of wrought-iron. I have shown the cutting-edges of the jaws as standing transversely to the frame, but they may stand in line with it to adapt the tool for cutting off long pieces of metal.
I am aware of the patent granted to V. A. Dunn, March 10, 1868, for a blacksmiths hardy, in which the lower jaw of the shears constitutes one irm of a lever, having its fulcrum on the stem of the stationary upper jaw, and provided' under its other a-rm, upon which the blow is struck, with a spring, the free end of which bears against the anvil-face. This construction of the tool necessitates that its stationary jaw be securely fixed to the anvil before it can be used, and it is more particularly in this i espect that the tool I have described radically differs from it. It is complete in itself', and can be applied to any ordinary anvil; need not be secured to it, so that it may be readily removed when not wanted.
What I claim as my invention, and desire to secure by Letters Patent, is-
The herein-described blacksmit-hs hardy, consisting of a base, A1, vertical arm A2, helve B1, spring O, and swed ges or cutters which are formed upon the base A1 and helve B1, the base portion resting upon the anvil throughout its entire length, except that part which enters a recess formed therein for receiving it thereon, and the spring being made to bear upon the rear end of the helve B1 and the point or projection b', to prevent its being thrown too far back, the parts being constructed substantially as and for the purpose set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
CHARLES F. MOORE.
