Description: |
| Brown & Allen - patent attorneys
A "Little Giant" drill chuck has been seen with the patents dates corresponding to 148,788, 315,684, and 315,685. That example had the Westcott Chuck Co. name, which changed its name from Oneida Steam Engine & Foundry Co. in about 1886.
The object of my invention is to prodiice a chuck more easily, simply, quickly, and effectively adjustable than the chucks heretofore in use, for the griping and holding of varioussized drills, metallic rods, bars, wires, &c., for the purpose of operating the same in lathes or other machines. My invention consists in the combination, with a chuck-body or face-plate, of two movable and adjustable jaws, provided with triangular tongues, so arranged with reference to each other that when the jaws, sliding in a diametrical groove or recess in the faceplate, approach each other the tongues of each jaw penetrate between the tongues of the other jaw, and which jaws are operated and made to close in upon or release at will the object to be held by a right and left handed screw, working in corresponding right and left handed screw-threads in the jaws themselves. |
