IMPROVEMENT IN BLACKSMITHS TONGS- Specification forming part of Letters Patent No. 190,457, dated May 8, 1877 application filed March 19, 1877.

To all whom it may concern Be it known that I, JAMES H. GREGORY, of Columbia, in the county of Maury and State of Tennessee, have invented a new and useful Improvement in Tongs, of which the following is a specification:

Figure l is a plan view of my improved tongs. Fig. 2 is a detail side view of the detachable jaws. Fig. 3 is a detail cross-section of the same, taken through the line as m, Fig. 2. Fig. 4 is a detail side view of the handle. Fig. 5 is a perspective view of the stationary jaws and the connecting-bar. Fig. 6 are de tail perspective views of two difi'erentkinds of false jaws.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish tongs which shall be so constructed that they may be used for holding two pieces of iron together, either straight or at any desired angle, for welding; that they may be used as a clamp, for holding the two ends of a tire with any desired lap, or for holding a piece or splice to be inserted in a tire; that can be used for holding various kinds of blades and cutters to be ground, and for other similar purposes.

The invention consists in an improved tongs, formed by the combination of the bar, the stationary ja'ws, provided with a set-screw, the detachable jaws provided with aset-screw, and

. a keeper, and the handle, provided with a keeper and a set-screw, with each other; and in the combination of the false jaws, provided with the keepers, with the jaws of the tongs, as hereinafter fully described.

Arepresents a bar, of any convenient length, to one end of which is riveted the lower one of the jaws B. The jaws B are made of a bar of elastic metal, bent into U shape, and held together by a hand-screw, b, passing through one of said jaws and swiveled to the other.

(l are jaws exactly like the jaws B, and held ceive the bar A, so. that it may be readily slipped on or ,ofi' the said bar A, and adjusted at any desired distance from the stationary jaws B. i

- D is a handle, which may be of'any convenient length, and to the side of the forward end of which is attached a keeper, d to receive the cross-bar A. The handle'D may be placed upon either side of the movable jaws B G, as may be desired, or as the character of the Work may require, and is secured in place, when adjusted, by a set-screw, d

False jaws of any desired form may be used upon the jaws B O, to prevent them from becoming unduly heated, and which are providedwith keepers e, to receive the said jaws B O, and keep the said false jaws in place.

A third set of jaws may be placed upon the cross-bar, to enable long pieces of iron to be more readily balanced, and to insure accuracy of position.

Having thus described my invention, I claim as new and desire to secure by Letters Patent a 1. An improved tongs, formed by the combination of the bar A, the stationary jaw B, provided with the set-screw b, the detachable jaw 0, provided with the set-screw c and the keeper and the handle D, provided with the keeper (1 and the set-screw d with each other, substantially as herein shown and described.

2. The combination of the false jaws E, provided with the keepers e, with the jaws B C of the tongs A B O D, substantially as herein shown and described.
