Torch

A torch comprising:

• an outer cylindrical tube centered about a predetermined longitudinal axis;
• a valve body at a first end of said tube having inlets to be connected to sources of fuel and oxygen;
• two tubes smaller in diameter than said outer tube connected to said valve body and projecting therefrom within said outer tube essentially parallel to said axis and toward a second end of said tube;
• manually actuated valves carried by said body for controlling the delivery of fuel and oxygen from said inlets to said smaller tubes respectively;
• a first hinge part at said second end of said tube connected rigidly to said smaller tubes and containing two separate passages for receiving fuel and oxygen from said two smaller tubes respectively;
• a second hinge part detachably connectable to said first hinge part for relative rotary adjusting movement about a hinge axis disposed essentially transversely of and essentially intersecting said longitudinal axis of said outer tube and containing two passages communicating with said two passages respectively in said first hinge part to receive fuel and oxygen respectively therefrom in any relative angular setting of the second hinge part within a predetermined range of movement thereof relative to the first hinge part;
• a nozzle detachably carried by said second hinge part and communicating with said passages therein to receive fuel and oxygen from the passages and constructed to emit both the fuel and oxygen to produce a flame which emits from the nozzle essentially radially of said second axis and is adjustable angularly about said second axis by angular adjustment of said second hinge part;
• said outer tube having an internal diameter slightly greater than the maximum dimension of said first hinge part transversely of said longitudinal axis to pass said first hinge part axially through said outer tube, in a relation enabling said outer tube to be moved to an assembled position about said smaller tubes by bodily advancement of said outer tube axially past said first hinge part while received thereabout;
• said valve body and said first hinge part having short cylindrical external surfaces which project into and are close fits within opposite ends of said outer tube in said assembled position thereof;
• fastener means for retaining said outer tube in said assembled position;
• said first hinge part having at one side thereof a generally flat fluid conducting face at which said two passages of the first hinge part terminate and which extends essentially transversely of said hinge axis, said generally flat face being disposed essentially in a plane which contains said longitudinal axis of said outer tube and which extends essentially diametrically with respect to said longitudinal axis and transversely of said second axis, said face having a maximum width transversely of said longitudinal axis of the outer tube which is just slightly less than the internal diameter of said outer tube;
• said second hinge part having a fluid conducting face opposite and closely proximate to said face of the first hinge part and at which said passages of the second hinge part terminate;
• deformable seal means between said fluid conducting faces disposed essentially in said plane which extends diametrically with respect to said outer tube and positioned to pass fuel and oxygen streams from said first hinge part to said second hinge part in sealed isolation from one another;
• said first hinge part, at a second side thereof, having an external surface curved essentially cylindrically about said longitudinal axis of said outer tube and of a diameter approximately corresponding to the internal size of said outer tube to pass the latter about and past said first hinge part, while said generally flat fluid conducting face extends essentially diametrically across the inside of the outer tube;
• said first hinge part having a flat external surface extending along said second side thereof and essentially parallel to said longitudinal axis of said outer tube and to said diametrical plane and to said generally flat face of the first hinge part and truncating said cylindrically curved external surface of said first hinge part and carrying marking means coacting with marking means on said second hinge part to indicate different angular settings of the second hinge part, nozzle and produced flame;
• and
• a threaded fastener centered about said hinge axis and extending through a central opening in said second hinge part and axially past said closely proximate faces of the two hinge parts and connected threadedly into said first hinge part in a relation mounting the second hinge part to the first hinge part for rotary movement about said hinge axis;
• said two hinge parts and said nozzle having together a combined maximum length in the direction of said longitudinal axis of said outer tube which is not substantially greater than the length in that direction of said two smaller tubes;
• said threaded fastener having a shoulder which is clamped against said second hinge part in retaining relation, and having a reduced diameter tubular shank with external threads connected to said first hinge part and containing an internal passage opening at one end into one of said passages in said first hinge part, said tubular shank having at an opposite end thereof a side wall opening near said shoulder for placing said internal passage in communication with one of said passages in the second hinge part.
