Abstract

An torch having a configuration for having a plurality of self sustaining positions is disclosed. Specifically, the present invention discloses a flexible torch sleeve including a plurality of pivotable elements in combination with a torch tip that reduces or eliminates thermal conductivity by the plume to the torch sleeve, thus enabling the adjustment of the sleeve to a variety of self sustaining positions during operation.

Claims

1. A flexible torch assembly for supplying a fuel source to a heat source, said assembly comprising:

(a) a torch tip having an annulus therein;

(b) a fuel line having a first end and a second end, said fuel line first end being in communication with the torch tip annulus;

(c) an adapter for connecting the fuel line to the fuel source, the adapter being engaged to the fuel line second end;

(d) at least one sleeve element, the sleeve element defining a annulus for containing and supporting the fuel line, the sleeve element being pivotably engaged with the adapter, thus facilitating a variety of supported, adjustable positions for the torch tip; and

(e) means for restricting the rotating the sleeve element around the radius of the sleeve element annulus.

2. The assembly of claim 1, further comprising at least one ear on said adapter and at least one reciprocal indent on said sleeve element engaging the ear thereby creating a pivotable engagement between the adapter and the sleeve element which restricts the rotation of the sleeve element around the circumference of the adapter.

3. A flexible torch assembly for enabling a variety of self-sustainable, adjustable positions for the application of fuel to a torch heat source, the assembly comprising:

(a) a torch tip, the torch tip including a distal portion and a proximal portion;

(b) a fuel line having a first end and a second end, the second of the fuel line being frictionally engaged to the proximal portion of the torch tip;

(c) an adapter for connecting the first end of the fuel line to the fuel source, the adapter being frictionally engaged to the first end of the fuel line;

(d) a plurality of sleeve elements, said elements being connected so as to define a sleeve section having a proximal end and a distal end, the sleeve section defining an annulus for containing and supporting the fuel line, the distal end annulus of the sleeve end extending approximately to the second end of the fuel line, the proximal end of the sleeve section connected to the adapter, thus facilitating a variety of self supported, adjustable positions for the torch tip.

4. The assembly of claim 3, further comprising means for restricting the rotating the sleeve section around the radius of the sleeve section annulus.

5. The assembly of claim 3, further comprising at least one ear on the adapter and at least one reciprocal indent on the sleeve element on the proximal end of the sleeve section, said indent engaging the ear, thereby facilitating a pivotable engagement between the adapter and the sleeve element which restricts the rotation of the sleeve element around the circumference of the adapter.

6. The assembly of claim 3, further comprising at least one ear on a first element of one of the plurality of the sleeve elements and at least one reciprocal indent on a second sleeve element engaging the distal end of the first sleeve element, said indent engaging the ear, thereby facilitating a pivotable engagement between the adapter and the sleeve element which limits the rotation of the sleeve element around the circumference of the sleeve section.

7. The assembly of claim 3, wherein each of said plurality of sleeve elements having an rounded, upper portion and a broader, lower portion for receiving an upper sleeve element portion, whereby the upper and lower portions facilitate a pivotable connection between the sleeve elements through a ball and socket configuration.
