Abstract: A gate support system for the free end of a swinging gate. The system can be secured to the free end of an existing gate or it may be included as an integral part of the gate at the time of manufacture. The system includes (a) an elongated support; (b) a foot member carried by the support member and being vertically moveable relative to the support member between raised and lowred positions; (c) bias means for biasing the foot member to the raised position; and (d) a lock for locking the foot member in a desired vertical position relative to the support member. When the gate has been pivoted to a desired position, the foot member can be pushed downwardly until it rests firmly on the ground. The lock will hold the foot member in a lowered position where it will support the weight of the free end of the gate. A trigger can be activated to release the lock and enable the foot member to move to a raised position.

Abstract: An ergonomic die buffer comprises a load-bearing base having a central axis extending longitudinally through the midpoint of the load-bearing base. The load-bearing base also comprises a longitudinal axis that may be coaxial with the central axis of the load-bearing base or displaced therefrom. A neck portion is operatively connected to the base and a foot is connected to the neck portion. The neck comprises a central axis, such that the neck is connected to the base coaxially with the longitudinal axis. When the longitudinal axis is displaced from the central axis of the load-bearing base, there is greater contract between the topside surface area of the base and the associated die. The foot comprises at least one flat surface in order to provide greater surface contact between the topside of the base and an associated die. The die buffer may be secured to an associated die either by magnets or through a spring-loaded mechanism.
