Abstract: Purging of a gas supply line is effected using a serviceman's purging tool having a hose for attachment to the supply line with an opposite end of the hose attached to a burner nozzle carried on a support frame. The burner nozzle is arranged to generate a stream of the gases exiting from the pipe to be purged. The frame carries a receptacle for a propane torch and angles the burner of the torch so as to be directed across the stream of gas from the supply pipe. The burner from the torch thus provides combustion of the purged non-ignitable products from the supply pipe until the ignitable gas reaches the nozzle whereupon the ignitable gas is ignited indicating that the pipe is purged. The receptacle comprises a cylindrical sleeve for receiving the tank of the propane torch and a bracket for guiding the nozzle of the torch across the stream.

Abstract: It consists of a cylindrical tube carrying a spring inside with a hook on one end to engage the fixed trunk hasp and a ring or closed loop on the other end to be lockably engaged by the trunk latching mechanism usually carried on the trunk lid. Once the hook is engaged with the fixed ring of the trunk, the lower end of the tube is manipulated so that a pair of opposed slots in the lower end of the wall of the tube engage upon the ring or hasp of the trunk so that the spring is under relatively heavy tension and thus acts as a substantially rigid link when the trunk lid is closed and locked upon the other end of the spring.
