The first end has an orifice through which a flame is discharged. The burn tube is one-piece from the first end to the second end. The burn tube has an expanded portion located adjacent to the first end and a flame guide located entirely inside of the burn tube adjacent the first end. A method of making the burn tube and torch is also provided.

Claims (31)

1 . A torch comprising:

a burn tube having a first end having an opening through which a flame is discharged and a second end spaced from the first end, said burn tube being one-piece from the first end to the second end;

said burn tube having an enlarged portion located at said first end; and

a flame guide located entirely inside of the burn tube adjacent to the enlarged portion.

2 . The torch of claim 1 further including a valve for controlling the flow of fuel to said burn tube.

3 . The torch of claim 2 further including a control for controlling said valve.

4 . The torch of claim 1 further including an igniter for igniting the fuel in the burn tube.

5 . The torch of claim 4 wherein said igniter is a piezoelectric igniter.

6 . The torch of claim 4 wherein a trigger is movably supported by said body, said trigger actuating said igniter.

7 . The torch of claim 4 further including an electrical conductor connected to said igniter such that when the igniter is actuated a spark is generated by the conductor.

8 . The torch of claim 7 wherein the spark is created between the burn tube and the conductor adjacent the flame guide.

9 . The torch of claim 1 wherein said burn tube is stainless steel.

10 . The torch of claim 1 wherein said flame guide is brass.

11 . The torch of claim 10 wherein the flame guide is staked to said burn tube.

12 . The torch of claim 1 wherein the flame guide is positioned in a non-enlarged portion of the burn tube adjacent the enlarged portion.

13 . The torch of claim 1 wherein the flame guide is positioned in the enlarged portion located adjacent a non-enlarged portion of the burn tube.

14 . A burn tube for use in a torch comprising:

an integral, one-piece tube having a first end having an opening through which a flame is to be discharged and a second end remote from said first end adapted to receive a fuel;

said burn tube having a larger diameter portion located adjacent to said first end and a smaller diameter portion; and

a flame guide located entirely inside of the burn tube adjacent.

15 . The burn tube of claim 14 wherein said tube is stainless steel.

16 . The burn tube of claim 14 wherein said flame guide is brass.

17 . The burn tube of claim 14 wherein the flame guide is staked to said tube.

18 . The burn tube of claim 14 wherein the flame guide is positioned in the smaller diameter portion of the tube adjacent the larger diameter portion.

19 . The burn tube of claim 14 wherein the flame guide is positioned in the larger diameter portion located adjacent to the smaller diameter portion of the burn tube.

20 . A method of making a torch comprising:

forming a one-piece burn tube having a first diameter, a first end and a second end;

expanding a burn tip by expanding the first end of the burn tube to a second larger diameter; and

securing a flame guide entirely within said burn tube adjacent said first end.

21 . The torch of claim 20 wherein said flame guide is staked to said burn tube.

22 . The torch of claim 20 further crimping the second end of the burn tube.
