Abstract
A swivel head assembly for a dual head oxy-fuel torch which incorporates a fixed oxygen delivery head and a 360 degree rotatable fuel delivery head mounted coaxially upon the oxygen delivery head, such that regardless of whether the torch is pushed forward, drawn backward or manipulated to either side, the fuel delivery head can be readily repositioned relative to the oxygen delivery head so as to always lead the delivery of oxygen for preheating, thus accommodating ease of arm movement and avoiding the need for cumbersome body movement and positioning around the target cutting surface.
Claims21
A delivery head assembly for use with a cutting torch, comprising:
- (a) a first delivery head for delivering a source of oxygen to a cutting surface along a first axis;
- (b) a second delivery head for delivering a primary source of cutting fuel to said cutting surface along a second axis;
- (c) one of said first delivery head and said second delivery head being rotatable about the other said delivery head such that delivery of said cutting fuel is positionable to always precede delivery of said oxygen along said cutting surface;
- and
- (d) said second delivery head includes a collar member which surrounds a portion of said first delivery head in movable relation thereto, and creates a sealed chamber through which said fuel may pass.
A delivery head assembly for use with a cutting torch, comprising:
- (a) a first delivery head for delivering a source of oxygen to a cutting surface along a first axis;
- (b) a second delivery head for delivering a source of fuel to said cutting surface along a second axis;
- and
- (c) one of said first delivery head and said second delivery head forming a sealed movable chamber around the other said delivery head to facilitate angular adjustment of said first delivery head and said second delivery head relative to one another.
A delivery head assembly for use with a cutting torch, comprising:
- (a) a first delivery head for delivering a source of oxygen to a cutting surface along a first axis;
- (b) a second delivery head for delivering a source of fuel to said cutting surface along a second axis;
- (c) said second delivery head having a collar which surrounds a portion of said first delivery head, said collar forming a sealed chamber around said portion of said first delivery head through which fuel may pass;
- and
- (d) said collar being rotatable around said first delivery head to facilitate angular adjustment of said second delivery head relative to said first delivery head.
A method of delivering oxygen and fuel from a cutting torch to a cutting surface, comprising the steps of:
- (a) providing a first delivery head for delivering a source of oxygen to the cutting surface along a first axis;
- (b) providing a second delivery head for delivering a source of fuel to the cutting surface along a second axis;
- (c) mounting said second delivery head upon a collar which surrounds a portion of said first delivery head and is rotatable around said first delivery head, said collar forming a sealed chamber around said portion of said first delivery head through which fuel may pass to said second delivery head;
- (d) delivering oxygen to said cutting surface through said first delivery head;
- (e) delivering fuel to said cutting surface through said second delivery head via passage through said sealed chamber formed around said portion of said first delivery head.
