Embodiment Construction

[0010] The figures show a quick connect fitting for connecting a fuel cartridge or tank 1 to an appliance such as a welding torch or torch tube 2 . Tank 1 can hold fuels such as propane, propylene, butane, MAPP gas, etc. The tank 1 includes a port for communicating the inside of the tank 1 with the outside. A first connector 6 is located within the port for connecting the canister 1 into the torch barrel 2, as will be described shortly below. The torch tube 2 includes a valve assembly and a fuel line 5 for controlling the flow of fuel from the canister 1 to the burner tube 8 . The fuel is ignited in the burner tube 8 by eg a piezoelectric igniter 10 . A controller for adjusting the size of the flame is also available. A second connector 12 is secured to the end of the torch barrel 2 for detachable connection to the first connector 6, as will be described below. While the invention is described with particular reference to a welding torch, it is to be understood that the fi...

Abstract

The invention relates to a gas appliance. A coupling for attaching a canister to an appliance comprises a first connector on the canister comprising screw threads and a groove and a second connector on the appliance that comprises a slip ring. The slip ring retains the canister on the appliance. An appliance comprises a canister having screw threads. A coupling connects the canister to the appliance separate from the screw threads where the coupling locks the appliance to the canister without rotating the appliance relative to the canister. The coupling locks the appliance to the canister when the canister is moved axially relative to the appliance. A canister is provided that has a connector comprising a set of screw threads for attaching the canister to a first type of appliance, and a groove for attaching the canister to a second type of appliance. A method of connecting a canister to an appliance is also provided.

Description

[0001] This application claims the benefit of US Provisional Application No. 60 / 927,715, filed May 4, 2007, the entire disclosure of which is incorporated herein by reference. technical field [0002] This invention relates generally to welding torches or other gas burning implements, and more particularly to a fitting for connecting a fuel tank to a welding torch barrel or other implement. Background technique [0003] The present invention relates to welding torches, such as propane, propylene, butane, mixed gas or MAPP fuel torches, which use a fuel source ignited by a spark generated by, for example, a piezoelectric igniter (collectively referred to as "welding torches"). torch"). This torch is used for heating, brazing, brazing, welding, and more. [0004] Fuel tanks in known welding torches are detachably connected to the torch barrel by means of a helical threaded connection. Typically, the canister includes an external helical thread threadably engageable with an i...
