IMPROVEMENT-{INL- P lPE TONGS' AND C U TTiERS Specification forming part of Letters Patent No. 197,658, dated November 27, 1877 application file August 22, 1877.
To all whom it may concern:
Be it known that I, ANTON OCHSNER, of the city of New Haven, in the county ofNew Haven and State of Connecticut, have invented certain new and useful Improvements in Pipe Tongs and Gutters and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.
Figure 1 represents a side elevation of my improved instrument arranged for use as a pipe-tongs, the side of the block for holding the detachable jaw being partly broken away.
and cutter, and B an externally rectangular tubular block for holding the straight jaw O of a pair of pipe-tongs. D designates the curved jaw of said tongs, which is pivoted at its rear end to a lip, a, on handle A, near the inner end of block B.
The rear end of said jaw D is provided with a short additional handle, D, against the under side of which bears one end of a spring, E, the other end of said spring being secured .to handle A. The action of said spring is to force said handles apart, and thereby force the jaws together, so as to gripe pipe K. When said handles are forced together by a firm grasp the jaws open. The inside ofthe lower part of curved jaw D is provided with a stop,
. cl, which engages with block B, and prevents said curved jaw from being turned too far forward by the action of said spring E.
The rear part of the central passage 12 of tubular block B is screw-threaded to receive an adjusting-screw,-F, which operates against the inner end of the shank C of straight jaw 0. By means of said adjusting-screw said straight jaw may be moved toward or from said curved jaw, thereby varying the distance between them, so as tosuit the size of the pipe, without throwing the curved jaw D too far back. Said straight jaw is clamped in any desired position of such adjustment by means of a small clamping-screw, G, which works through one side of tubular block B, and bears against a flattenedspace, c, in the side of said shank O. Said straight jaw O is provided with a block, 0, having an inclined upper surface, which presses against the tube that is to be held, so as to grasp it securely, with the cooperation of curved jaw D.
H designates a chisel, having a shank, H, with flattened space h and an inclined cuttingedge, It.
'To convert my implement into a pipe-cutter, it is only necessary to withdraw straight jaw O and substitute chisel H. The adjustingscrew and clamping-screw, hereinbefore described, operate on the shank of the chisel precisely as 011 the shank of the straight jaw. Various changes may be made in the devices above described without departing from the spirit of my invention. For instance, a spiral or any suitable form of spring may be used between the handles A and D, and their pivoting may be effected in any convenient manner.
After a pipe has been cut by the cutting devices above described, its exterior at the cut is generally somewhat rough and ragged. To remove the raised pieces of metal and reduce said exterior to perfect smoothness, I set into curved jaw B a pin or stud, I, which has a sharp edge, i, toward the handle A.
J designates a longitudinal recess or groove in the inner face of said jaw, extending from said cuttingedge i toward said handle. A part rotary motion of the implement (the rough edge of the cut pipe being placed in said groove J) causes edge 45 to shave off all raised bits of metal, and produce the smoothness desired.
These devices are also susceptible of modifioation without departing from the spirit of 2. The combination, in a pipe-cutter, of a my invention. straight jaw and suitable handles, with a 'Having thus fully described my invention, curved jaw, having groove J and pin I, having What I claim as new, and desire to secure by trimming-edge i, substantially as set forth.
