Abstract: A pneumatic die transfer system for a press machine comprises at least two primary roller rails and at least two secondary roller rails set in respective T-slots in a bolster. The primary roller rails are perpendicular to the secondary roller rails. Airbags below each roller rail are selectively inflated to elevate either the primary or the secondary roller rails above the bolster face. The secondary roller rails each have a plurality of discontinuities configured to receive the primary roller rails and their associated airbags in an intersecting fashion. As a result, the bolster can be easily fabricated with intersecting T-slots and relatively few roller rails are needed to achieve fully orthogonal conveyance of a heavy die over the face of a bolster.

Abstract: A positive lock pin for locking a plurality of objects together includes an upper housing in communication with a handle housing. The handle housing has a shaft member located therein. The shaft member is rotatable with respect to the handle housing and has a slot formed in an upper portion thereof. The shaft member also has a pair of recesses formed therein. The shaft member is in communication with a pair of retention mechanisms disposed within the handle housing. Each of the pair or retention mechanisms is in communication with a respective opening formed in the handle housing. The pair of retention mechanisms are moveable between a locked position where an outermost point thereof extends outwardly from a respective opening and an unlocked position wherein the outermost point does not extend outwardly from the respective opening and a respective retention mechanism rests in one of the recesses. The movement of the retention mechanisms occurs upon rotation of the slot and the shaft member.

Abstract: A positive lock quick release pin for locking a plurality of objects together includes a handle portion which is in communication with a handle housing. The handle housing has an interior cavity within which a shaft member is disclosed. The pin also includes a ball retention mechanism located in the handle portion that is moveable between a locked position where the mechanism extends outwardly of an opening formed in the handle housing and an unlocked position where the ball mechanism extends no further than the outer edge of the opening. The ball retention mechanism is moved between the locked position and the unlocked position by reciprocation and rotation of the shaft member within the handle housing.

Abstract: In one embodiment, a utility belt comprises a belt adapted to be worn around the waist of a wearer, and a number of belt components removably mounted on the belt. Included among the number of belt components is a flexible pouch arrangement with a number of expandable pockets having a puncture resistant interior surface. The flexible pouch arrangement can be composed of a fabric, such as a nylon mesh, coated with a puncture resistant material, such as poly-vinyl chloride, that has sufficient stiffness to retain the shape of the pouch arrangement. The flexible pouch arrangement can also include a first pocket having an outer wall and a pair of loops affixed to the wall. A detachable pocket includes a pair of pressure adherent, or Velcro, strips corresponding to the pair of loops. The detachable pocket can be removably mounted on the first pocket by engaging the Velcro strips about a corresponding one of the loops.
