Abstract: An improved bag holder and collector for receiving grass clippings, leaves, etc., in a top hopper for discharge into a collection bag removably mounted below the hopper. The hopper is formed by a pair of downwardly inwardly sloping end walls and a pair of vertical side walls which terminate with a rectangular-shaped horizontal bottom wall. A circular discharge opening is provided in the center of the bottom wall, with the remaining portion of the bottom wall forming a flat shelf area surrounding the opening. A cylindrical collar is mounted beneath the bottom hopper wall concentric with the discharge opening. Clamping ring means removably mounts a collection bag on the collar for receiving the materials discharged through the hopper opening. The hopper is supported between a pair of upstanding end panels having wheels attached to the bottoms thereof for movably supporting the hopper.

Abstract: A safety guard for a machine tool, such as a punch press, having an operating part, such as a ram, having a control member. The guard comprises gates between the operating part and a machine tool operator. One of the gates is slidable across the front of the machine tool. Another of the gates is disposed at the side of the machine tool and has a pivot on which it is swingable. The sliding gate carries a control actuator and closes on a path which intersects the free end of the swinging gate which has a bumper. The sliding gate is powered by an air cylinder having a control accessible to the operator. When either gate is open, the machine tool control member is deactuated and there is no danger that the machine tool will operate to endanger the operator's hands. The machine tool operator actuates the gate control to close the sliding gate.
