Description:
The present invention consists:

First, in providing the frame of the ordinary dog to a lathe with a frame, arranged to play or slide thereon in such manner, with relation thereto, as to have a motion for the entire length, if not beyond the inclined sides of .the dog-frame, against which, in the ordinary dog, the article to be turned is pressed, and held by the set screw of the dog, whereby the clog is rendered more universal in its application, arfd more certain, sure, and reliable in its hold upon the article placed in it to be turned.

Second, in providing the adjustable slide-frame, herein above referred to, for the dog, with angular extension arms, meeting at a common point in the centre line of the dog, and there, by a lug adapted to move in a guiding groove or way of tho dog-frame, for the purpose of avoiding any lateral play of the adjustable, slide-frame upon the dog, as it is moved upon the dog and imparting a more steady, stiff, strong, and rigid action when grasping the article in the dog.

Third, in constructing the adjustable slide so as to embrace both sides of the dog-frame; and

Lastly, in a novel construction, whereby the slide can be applied to and fastened upon the dog, so as to embrace both its sides.
