Abstract: A pressure testing apparatus for a fire hose utilizing a source of water under relatively low pressure and flowable at relatively high volumetric rate. The apparatus employs a manifold using a hose filling valve. The source of water communicates with the manifold and a low pressure inlet of a pump. The outlet of a pump pressurizes the manifold at a relatively high pressure. Check valves prevent back flow from the manifold to the source of water and the outlet of the pump. A regulator valve is positioned in the manifold to determine the highest pressure found in a portion of the manifold for filling and testing the fire hose.

Abstract: A rivet for holding together first and second members utilizing a shaft having first and second end portions. The first and second end portions of the shaft at least partially occupy the openings through the first and second members respectively. A cap having an internal bore grips the first end of the shaft which is extended through the first member. The cap has an enlargement including an exterior surface for frictionally engaging the opening through the first member. The shaft also includes an enlargement on the second end portion which is capable of frictionally engaging the second member.
