N-PETER8. PHDTOJJTHOGRAPNER. WASHINGTON D C 444444 r4 M r or U UNITED STATES PATENT OFFICE JOHN HOOHHELMER, OF HAMILTON, OHIO.
IMPROVEMENT IN STOCKS FOR SCREW-CUTTING DIES.
Specification forming part of Letters Patent No. 188,634, dated March 20, 1877; application filed September 17, 1875.
To all whom it may concern:
Be it known that I, JOHN HooHnEIMER, of Hamilton, Butler county, Ohio, have invented a new and useful Improvement in Die-Stocks for (hitting Screws; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
Figure 1 represents a side view of my new die-stock; Fig. 2, the face of the die-clamp, with a pair of dies inserted therein.
My present invention relates to certain improvements in the die-stocks; and consists in connecting the two branches of the stock by the use of a sleeve and arm, instead of the hinge, so as to give parallel adjustment to the dies; and in constructing the die-holder or clamp with overlapping lips upon one jaw, which fit over the other jaw of the die-clamp, as described herein.
In the drawings, A B denote the die-clamps or jaws connected to their respective side frames 0 D, through which the screw-bolt I passes to adjust the clamps with the dies S S toward or from each other. The side 0 has a cylindrical arm, F. constructed at right angles thereto, and represented in dotted lines, as inserted in a sleeve made through the part G of the frame D, which is provided with a square shank, H, to fit into the socket of a bit-stock. a: .1: denote the overlapping lips of the clamp.
This improvement enables the die-stock to be opened and closed in parallel planes. The die-stock may be used by means of the ordinary bit-stock, by inserting the shank H in the socket of the bit-stock.
Having described my impr0vement,I claim- The sleeve G, and arm F, in combination with the jaws A B, and screw-bolt I, substantially as described, for the purpose specified. Witness my hand this 10th day of May, A.
JOHN HOOHHEIMER. Witnesses:
H. P. K. PEoK,
JOHN M. DAVIDSON.
