Abstract: The invention is a system for use in a single-anvil hydraulic press or compression system for automatically selecting and changing both the upper and lower tooling. The system is installed between the upper and lower compression anvils of a hydraulic press. The upper portion includes a set of holders for upper tools and adjacent orientation structures or jaws. The upper tool holders and jaws are mounted on a horizontal member that may be moved such that one of the upper tools is "selected" by being placed immediately below the upper anvil of the press. As part of this selection process, the anvil removes the tool from the selected holder, and holds it using pneumatic suction. Then the horizontal member shifts over so that the upper anvil is situated directly above the adjacent orientation structure for that tool. To switch to a different upper tool, the horizontal member again moves the (empty) holder below the upper anvil, whereupon the pneumatic suction is removed causing the tool to drop into the holder.

To switch to a different upper tool, the horizontal member again moves the (empty) holder below the upper anvil, whereupon the pneumatic suction is removed causing the tool to drop into the holder.

Abstract: A tin cap dispenser for pneumatic nail guns that include a continues source of nails. The dispenser is also pneumatically activated and coupled to the operation of the nail gun. A pneumatically actuated handler arm member is reciprocally moved between two positions, one engaging a tin cap and the other one releasing it in alignment with a positioned nail also in coaxial alignment with the hammer of a nail gun. The timing of the tin cap handler arm member controls a valve assembly in series with the conventional trigger mechanism of the nail gun and another valve also in series that is activated by the handler arm member. A lock assembly inhibits the operation unless sufficient time is given to the feeding nails mechanism to get out of the way. The resulting device permits the continuous installation of tin caps on a flat surface.
