Abstract
Abstract A compact stock stop control assembly for use in stock forming machines, such as for instance a metal upsetting machine, for positioning the bar or rod of stock material with respect to the work area or die area of the machine. The assembly comprises a support embodying elongated movable abutments mounted on the support with one end of each abutment being adapted for positioning a respective bar or rod of stock relative to the machine. A control panel, disposed remote from the support and movable abutments, is provided, with control mechanism for expeditiously positioning the movable abutments relative to the support, and thus providing for the remote control adjusting of the position of the stock stop abutments with respect to the work area of die area of the machine. Means are provided for locking the stock stop abutments in selected position, and means are provided for sensing the movement of the abutments and visually indicating on the control panel the distance that the stock stop abutments are positioned from the work area of the machine. The highly compact assembly is adapted for use in different types of stock forming machines, and the stock stop abutments thereof can be expeditiously controlled remote from the location of the actual stock stop abutment mechanism.
