ABSTRACT:
A low cost pneumatic stock feeder for punch presses and the like wherein a one-piece U-shaped main frame is provided for supporting and guiding a reciprocating feed slide. One end of a stock gripper bar is pivotally secured to the feed slide while the other end thereof is adapted to be actuated by a fluid motor carried by said feed slide whereby an efficient mechanical advantage is afforded for the stock gripping action. A continuously acting friction braking means is provided for engaging just the longitudinal side corners of the stock material so that the latter may be yieldably held during the time when the gripper bar is released and so that there is a minimum of marring or scratching of that portion of the stock material from which parts are to be stamped.
