Abstract

The jack includes a flexible air-feed and operates between fixed and movable parallel plates, being fixed to the plates by retaining rings. A shaft may project axially from the moving plate, being used to attach alternative fittins, and the assembly may be mounted in a housing with handles. In the press function, a punch may be fixed to the shaft, the unit being mounted on columns fixed to a base plate.
