Abstract: A manual emergency tool assembly including a pair of tools, each of which has an operating head and a handle. The handles are formed to be telescopically engaged with each other. A locking arrangement is provided to secure the handles to each other in a fully telescoped relationship, and in intermediated telescoped relationships. A further locking arrangement provides for limited axial movement of the handles with respect to each other. The locking arrangement also provides for separating the tools for independent use of each tool or for use of the tools together in a configuration other than with the handle in a telescopic relationship.

Abstract: A hand-held pneumatic rescue tool may be driven from a bottled compressed gas. The driving gas is used only for the blow-striking stroke, while a compression spring is used to provide a force for the return stroke that is independent of the pressure of the driving gas. Thus, the pressure of the driving gas may be varied to adjust the impact force of the blows struck, without adversely affecting operation of the tool. By appropriate valving, the tool will operate continuously and automatically so long as driving gas is supplied, as determined by the operator.

Abstract: Control valves for a plurality of outlets supplied from a single fluid source are combined in a single manifold. Each outlet conduit is selectively connected to an inlet conduit by an independently actuatable source valve. Each outlet conduit is also provided with an independently actuatable discharge valve and a safety relief valve. A pressure gauge may also be connected to each of the outlet conduits. The conduits may be channels formed in a solid manifold, and the independently actuatable valves may be manually actuatable push button valves. A locking mechanism is provided for each of the push button valves.

Abstract: A rescue tool with an extended hollow housing has the shaft of a tool bit mounted in one end thereof for reciprocable motion. A substantially solid hammer is manually driven to strike the tool bit, the hammer extending the greater portion of the length of the housing when striking the tool bit. Manual actuation of the hammer is achieved by means of a shroud having a handgrip on its outer surface, the shroud being secured to the hammer at the end away from the tool bit. The hammer may be locked with respect to the housing to provide a pry bar of two different lengths. Securing the hammer to prevent complete withdrawal of the hammer from the housing is achieved by an easily removable snap ring arrangement.
