F. NEVERGOLD AND G. STACKHOUSE, OF PITTSBURG, PENNSYLVANIA.

COMBINED DRILL AND BLACKSMITHS TONGS.

Specification forming part of Letters Patent No. 55,696, dated June 19, 1866.

To all whom it may concern:

Be it known that we, F. NEvEEGoLD and G. STACKHOUSE, of the city of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and Improved Drill-Tongs; and we do declare that the following is a full and exact description thereof, which will enable others skilled in the art to make and use our invention, reference being had to the accompanying drawings, in which is represented a perspective view of our improved drill-tongs.

Our invention consists in an improved drilltongs for drilling metal, stone, wood, or any other materials, constructed and operating as follows:

A and B are the two jaws of an iron or steel tongs, having branches or handles A and B', and so held together and pivoted by the bolt C as to be able to open and shut as any other tongs.

The top jaw, A, is terminated by a circular disk, through the center of which is bored a hole, and upon which is titted the disk E of the frame F. This disk E is provided with two semicircular slots, g g, which allow of two small bolts, HH, passingthroughits thickness, allowing the frame F to be turned at pleasure at different angles with the center of the tongs, but holding it quite rmly when the bolts H H are tightened.'

G is a spindle, with its socket J, for holding the drill K. MM are gearings of any dimension or pitch suitable for transmitting motion from the shaft N to the spindle G; and O is the crank and handle by which motion is given to the shaft N. In any case where it is advisable the crank and handle O can be placed directly 011 the spindle G at the point P.

R is a disk, which is fastened to the jaw B, and can be removed at pleasure to be replaced by any other of proper shape for special purposes, either pivoted, screwed, or otherwise connected with the jaw B. T is a piece of Work to be drilled.

The operation of our drill-tongs is as follows: The workman, holding both branches A and B of the tongs in his left hand, will pinch between the jaws A and B the piece of This drilltongs will be found to be admirably adapted to many different works. Its use will be advantageous when any holes are to be drilled in Work already put up, or in such pieces as cannot be brought under the drillpress, as it can be made to drill in almost any position with great facility.

What We claim as our invention, and desire to secure by Letters Patent of the United States, is

l. The new and improved tool which we call a drill-tongs,7 constructed as described, or its equivalent.

2. The combination of the tongs A B with the frame F, spindle G, wheels M M, shaft N, crank O, and drill K, as described and for the purpose specified.

3. The disk D on the tongs A, in combination with the disk E, the slots gg, and the bolts H H, for holding the frame Fin different position in relation to the tongs A B.

4. The combination of the piece R with the jaw B of the tongs A B', constructed and applied one to the other, as described and shown.
