Description
UNITED STATES PATENT OFFICE.
GEORGE A. GRAY, JR., OF CINCINNATI, OHIO.
BENCH-VISIE.
Specification of Letters Patent No. 26,266, dated November 29, 1859.
T 0 all whom it may concern:
Be it known that I, GEORGE A. GRAY, Junior, of Cincinnati, Hamilton county, Ohio, have invented a certain new and useful Improvement in Bench-Vises; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part of this specification.
The invention consists in a provision whereby the workman is enabled greatly to increase the grip or bite of the jaws.
Figure l is a side View of a bench vise embodying my improvement. Fig. 2 is an axial section through the upper screw. Fig. 3 is aA perspective view of a portion of the upper screw.
A a, is the fixed aw and shank. The aw and shank B b, are adapted for a parallel motion to and from the fixed jaw by means of the familiar appliance of two screws C, D, connected by an endless chain E. -A cylindrical projection C from the front end of the screw C is grooved (c) around its periphery to receive a pin e, which projecting inwardly from a hollow movable head F confines said head while permitting its rotation upon said projection. The movable head has a customary handle G.
H is a spring catchwhich at a certain point in the rotation of the head F, enters of itself a socket 7L in the screw C. The
portions of the screws which are within movable jaws are made slightly crowning.
Operation: A grip having been taken in the ordinary way, the operator While still grasping the handle with his right hand withdraws the catch H with his left and instantly reverses the handle G. In this movement the upper screw C remaining perfectly quiescent becomes a fulcrum for the jaw B b which now acting as a lever, has its upper end B powerfully pressed inward, by the retrograde motion of the lower screws D. By these means the customary screws D (heretofore employed only to preserve parallelism) becomes powerfully efe fective for an increased grip of the jaws, the action being performed by a simple reverse movement of the customary lever without stooping or detention.
A vise thus constructed permits the employment of a very short manageable handle.
I claim as new and of my invention- The described combination of the handle G loose head F and catch H with the jaws, screws and endless chain of a parallel bench vise.
In testimony of which invention, I hereunto set my hand.
G. A. GRAY, JR.
