TONGS OR CLAMP.

SPECIFICATION forming part of Letters Patent No. 753,620, dated March 1, 1904. Application filed December 1,1903. Serial No. 183,330. (No model.)

To all whom it may concern:

Be it known that I, PETER A. ORTH, a citizen of the United States, and aresident of Menno, in the county of Hutchinson and State of South Dakota, have invented a new and useful Improvement in Tongs or Clamps, of which the following is a full, clear, and exact description.

My invention relates to improvements in blacksmiths tools, the same being especially designed for service in operating on plow shares.

The object I have in view is the provision of a simple tool adapted to grasp a heated plowshare, so as to hold it in shape when immersing it in a bath for tempering the share. The tool affords protection to the edge of the share to prevent it from taking too hard a temper, and the tool is adjustable to plowshares of different sizes.

Further objects and advantages of the invention will appear in the course of the subjoined description, and the actual scope thereof will be defined by the annexed claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

Figure 1 is a perspective view of a blacksmiths tool constructed in accordance with my invention, and Fig. 2 is a horizontal section on the line 2 2 of Fig. 1 and on an enlarged scale.

My improveed tool consists principally of two members A B, each of which is bent at a point intermediate of' its length, as at a, in order to produce a jaw C and a handle D on the member A, while the other member B has 'a similar jaw E and ahandle F. Thebent portions (0 of the members are disposed in crossing relation, and each bent portionhas a plurality of openings 6, said openings of the jaws being disposed in coincident relation for the reception of a pivotal bolt or screw 0, which serves to operatively connect the members A B and complete the tongs. The jaw C of the member A is considerably longer than the jaw E of the member B, and the end portion of said jaw C is curved or deflected laterally, as at C. This jaw and its extension C are provided with acontinuous longitudinal groove or channel g, the same being produced by the employment of a plate or strip G and an intermediate spacing-strip g. (See Fig. 2.) The plate G and the strip g are fastened to the jaw C and its extension C by transverse rivets g or other suitable fasteners,-the several parts being bound solidly together by the fasteners, and the groove or channelbeing provided between the jaw and the plate Gr. This plate extends practicallythe full length of the jaw G and its extension C and, as shown by Fig. 2, I prefer to dispose the plate Gin inclined relation to the jaw, thus providing a tapering groove or channel g, which is adapted to receive the sharpened edge of a plowshare, as indicated by dotted lines in Fig. 2. The short jaw E on the member'B of the implement is also provided with a groove or channel it, the same being pro- I duced by fastening one or more spacing-strips h and a plate H to the jaw E. The strips h lie between the jaw E and the plate H, and the parts are bound solidly by the employment of rivets k or other fasteners. (See Fig. 2.) The jaw E and the-plateHare preferably arranged in parallel order, so as to produce a groove or channel it which is uniform in width, and this plate H extends practically the full length of the jaw E.

In the service of my implement a plowshare is heated until it partakes of the color known to those skilled in the art as a cherry red, and in order to straighten the share it is placed on a block and suitably manipulated. The. tongs are now employed for immersing the heated share in a bath of water, and to this end the implement is applied to the respective edges of the share in the manner shown by the drawings. The channeled jaw G is shaped to conform to the sharpened front edge of the share, and said jaw, receives said edge of the share in its channel, so as to protect the edge when it is immersed in the bath. The channelh of the other jaw, E, receives the rear edge of the share, and .the two jaws cooperate in firmly holding the share in a straightened condition while it is under immersion in the bath. By fitting the sharpened edge of the share in the channeled jaw G and its extension C the water is prevented from having free access to the-sharpened edge, thus preventing the latter from becoming too hard in the tempering operation.

The implement may be adjusted so as to vary the space between the jaws thereof by sisting of bent members each having a jaw and placing the pivot-bolt c in different holes of ahandle, said members beingdisposed in crossthe members, and provision is thus made for ingrelation and pivotally connected bya transusing the implement on shares of different verse bolt, a plate fastened to each jaw, and 5 sizes. spacing-strips interposed between the jaw and 20 Having thus described my invention, Iclaim the plate and separating said parts to produce as new and desire to secure by Letters Pata longitudinal channel on the inner edge of ent the jaw.
