Abstract: Disclosed is an invention relating to golf tees on practice ranges and more particularly to the construction of a golf tee having a ball support portion associated with a piston portion, the piston being adapted to be vertically moveable within a housing secured within a base of the practice tee. In one embodiment, the piston and housing have a mechanism to detachably lock the two together and to provide controlled "drag" to relative movement of the two so as to provide a "feel" to the vertical adjustment of the ball support portion. In another embodiment, the ball support and piston are integrally molded of a flexible plastic material and the housing is of a harder plastic material. The piston reciprocates within the housing and has a lower end with a slit skirt encompassing a circular wire spring which forces the skirt outwardly with contact with the housing walls to provide the desired "drag".

Abstract: A fork-lift type truck for handling pallet loads comprising a plurality of superimposed layers mounted on slip sheets is provided with a push-pull load displacer having the capability for vertical movement substantially independently of the truck platform, to permit selective build-up or dispersal of the load, one or more layers at a time, using slip sheets for each segment of the load. The push-pull load displacer is of slender construction, including a pivotable actuator, to achieve a shallow envelope when retracted, for ready passage downwardly into the restricted space available between the pallet load and the load carrying structure of the machine.
