Abstract
Improvements in hydraulically controlled copy lathes, characterized by having the servo valve arranged along the cylinder, for the oscillation of both around the pivoted connection with the carriage in a plane such that they do not trip on the lathe bench in which the device has to be mounted; a lever arm pivoted in the device in a position such that it also does not trip on the lathe bed; a rod adapted to extend rigidly from the lever arm, parallel to the pivot thereof, and to carry the punch, at its free end; means for adjusting the extension distance of the rod from the lever arm, in order to place the punch in contact with a pattern coupled to the lathe, and means for transmitting movement of the lever arm to the valve spool.
