Abstract: A universal test stand kit for supporting an internal combustion engine during tests includes a pair of side frame members having upper and lower pieces joined together by end pieces and laterally extending tubular stubs. The side frame members are joined together by tubular crosspieces telescopically received in the tubular stubs. A forward engine support assembly is slideably mounted on each side frame member so that the assemblies can be moved longitudinally to accommodate different sizes of engine. Each forward support assembly includes an elongated track which is laterally moveable and provided with apertures for receiving bolts which may be threaded into tapped bores in the engine block from which oil pan bolts have been removed. A rearward engine support assembly is mounted on the side frame members so that the assembly can be aligned with the rear end of the engine to be tested.

Abstract: A fully automatic valve closing apparatus that is responsive to movement between the apparatus and a substantially fixed structure, wherein the apparatus includes a supporting frame on which is mounted a pressure activated actuator which is adapted to be fixedly mounted to a main in-line valve of a fluid flow system such as a gas or water utility line. A gas pressure activating system is operably interconnected between the fixed structure by means of a tripping mechanism defining a universal linkage device that removably engages a pair of pressure control valves. The main valve is moved to a closed position when movement occurs between the valve closing apparatus and the substantially fixed structure to which the universal linkage is movably attached. The apparatus which contains no electrical components is pneumatically operated from a self-contained power source.
