Baldwin & son-patent attorneys
My invention consists in making a tool-rest of a hemisphere or segment of the ball of a ball-and-socket joint, (or of the moving portion of a universal joint,) so that while the post always remains perpendicular to the plane of the lathe, the tool can be turned freely in a horizontal plane, or be so inclined at an angle to the post as to permit its point or cutting-edge to be elevated or depressed, to turn varying diameters, without elevating or depressing the post.
