Claim 6

A welding and cutting unit comprising a cutting torch having an elongated cylindrical handle portion having first and second ends, a finger tube projecting from the first end of the handle portion, a burner head on the end of sad finger tube, said handle portion having bolt holes in the second end thereof, a fitting overlying said second end of the handle portion, hollow bolts threaded in said bolt holes securing said fitting to said second end of the handle portion, said fitting having a depending leg with a pair of passages therein communicating with the hollow bolts, short tubes extending from opposite sides of said leg of the fitting registering with the passages therein, a cap carried on the outer end of each short tube, fuel and oxygen supply canisters having ends fitting said caps for detachably supporting said ends of fuel and oxygen supply canisters to said caps and means carried by said caps to release fuel and oxygen from the suspended canisters through the short tubes, the fitting, the hollow bolts, the handle, and the finger tube to the burner head.

Claim 7

The unit of claim 4 wherEin the mans for suspending the canisters on the caps are snap rings.

Claim 8

A cutting and welding torch comprising a torch body having an elongated handle portion with hoses extending from the rear end thereof, a fitting detachably connected to the remote ends of the hoses, said fitting having a depending leg portion with passages for fuel and oxygen, a tube extending laterally from each passage, caps suspended from the tubes, fuel and oxygen supply canisters suspended from said caps, and means on said caps for activating said canisters whereby fuel and oxygen will be supplied from the respective canisters to the fitting and through the hoses to the torch.

Claim 9

A cutting and welding torch comprising a torch body having an elongated handle portion with hoses extending from the rear end thereof, a fitting detachably connected to the remote ends of the hoses, said fitting having a depending leg portion with passages for fuel and oxygen, a tube extending laterally from each passage, caps suspended from the tubes, fuel and oxygen supply canisters suspended from said caps, and means on said caps for activating said canisters whereby fuel and oxygen will be supplied from the respective canisters to the fitting and through the hoses to the torch.

Claim 10

A portable torch unit comprising a torch body having a rear end with fuel and oxygen passages communicating therewith and a torch tip projecting from the opposite end receiving fuel and oxygen from said passages, a fitting bolted to the said rear end of the body having passages communicating with the passages in the body, a tube extending laterally from each passage, caps carried by the tubes each communicating with a passage in the tube, a fuel supply canister having an end received by one of said caps, a heat shielded chlorate candle oxygen generator having an end received by the other of said caps, means in said caps releasably securing the canisters in sealed relation therewith, and the cap suspending the oxygen generator having an activator for activating the generator.

Claim 11

A portable torch unit comprising a torch body having a rear end with fuel and oxygen passages communicating therewith and a torch tip projecting from the opposite end receiving fuel and oxygen from said passages, a fitting bolted to the said rear end of the body having passages communicating with the passages in the body, a tube extending laterally from each passage, caps carried by the tubes each communicating with a passage in the tube, a fuel supply canister having an end received by one of said caps, a heat shielded chlorate candle oxygen generator having an end received by the other of said caps, means in said caps releasably securing the canisters in sealed relation therewith, and the cap suspending the oxygen generator having an activator for activating the generator.

Claim 12

A portable torch unit comprising a torch body, a fitting on said body having a pair of passages, a tube extending laterally from each passage, a cap at the end of each tube a fuel supplying canister releasably suspended from one cap, a separate oxygen generator canister releasably suspended from the other cap, and a heat shield surrounding the oxygen generator canister.

Claim 13

A portable torch unit comprising a torch body, a fitting on said body having a pair of passages, a tube extending laterally from each passage, a cap at the end of each tube a fuel supplying canister releasably suspended from one cap, a separate oxygen generator canister releasably suspended from the other cap, and a heat shield surrounding the oxygen generator canister.
