Lathe-Dogs.
Patented April 29 AM, PHUTO-UTHBGHAPHIC ca MKQMURNL-Z's mucus) PATENT OFFICE.
CHARLES L. WIOKHAM, OF UTIOA, NEW YORK.
IMPROVEMENT IN LATHE-DOGS.
Specification forming part of Letters Patent No. 138,305, dated April 29, 1873; application filed August 3, 1872.
To all whom it may concern:
Be it known that I, CHARLES L. WICK- HAM, of Utica, in the county of Oneida and State of New York, have invented a new and Improved Bolt-Dog; and I do hereby declare that the following is a clear, full, and exact description thereof, which will enable others skilled in the art to make and use the same, by referringto the accompanyingdrawingforming part of this specification- My invention consists in making bolt-dogs or bolt drivers adjustable, which have heretofore been made solid, and thus avoid having to remove the bolt-dog from the face-plate of a lathe or other machine, and readjust another size each time a larger or smaller bolt or piece of metal is to be turned. Said invention relates to an improved apparatus for holding, in a certain position to a face-plate of a lathe or other machine, bolts or square metal while being worked or turned in the ordinary opertion; and itcconsists of an adjustable jaw having a shank which passes through a recess in an opposite but stationary jaw. Said shank of the adjustable jaw is provided with a rack, into which a projecting tooth catches. Said tooth is situated inside of the recess of the stationary jaw. The rack-shank is kept on the tooth and held fast by means of-a thumbscrew projecting through the upper part of the recess of the stationary jaw through which the rack-shank passes. The adjustable jaw is provided also with a dovetailed recess through which the shank or body piece of the stationary jaw passes, and serves to guide the adjustable jaw and keep it in a firm yet sliding position, all as hereinafter described.
Figure 1 is a front view of a bolt-dog, showing my improved apparatus with the several parts combined. Figs. 2, 3, and 4 are sections of Fig. 1 taken on the line mm. Fig. 5 is a front view of the adjustable jaw and rackshank. Fig. 6 is a section of Fig.1, showing the stationary jaw and its beveled shank. Fig. 7 is a view of thumb-screw.
Similar letters of reference indicate corresponding parts.
A represents a bolt-dog which is generally fastened to a face-plate of a lathe or other machine by means of a bolt through the hole H. E and G are the jaws, D and. F are the shanks, which are fitted in the recesses of the jaws E O. The shank D of the adjustable jaw E is provided with a rack, into which a projecting tooth, I, catches. Said tooth is situated inside of the recess of the stationary jaw O. The rack-shank D is kept on the tooth I, and held fast by means of a thumb-screw, J, projecting through the upper part of the recess of the stationary jaw (J through which the rack-shank passes. The adjustable jaw Eis provided with a dovetailed recess through which the beveled shank F of the stationary jaw 0 passes, and acts as a guide to the adjustable jaw E, and serves to hold it in a firm yet adjustable position.
Having thus described my invention, I claim as new, and desire to secure by Letters Patent- The improved lathe-dog, consisting of the jaw O, in one piece with the part A, and having a 'toothed mortise,"as described, and the jaw E and the toothed bar D, also in one piece, all as and for the purpose set forth.
CHARLES L. WIOKHAM.
