Abstract
Abstract An expendable flame tip for a gas-fired torch is made separable from the gas-mixing rear portion whereby a series of different size tips may be used with a single-mixed portion and only the front end of the torch need be replaced in the event of damage to the tip. The tip portion is formed from two tubular members by inserting one such tubular member within the other and swaging them together (over mandrels if desired). The torch tip is thus manufactured without the need of the now used expensive drilling operations as the gas passageways are formed by grooves formed in the tubular members.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
94 words
A two-piece torch tip for a gas-fired torch, comprising, in combination, a gas mixer piece, a flame end piece, each said piece having a plurality of passages therethrough for gas, said passages having given relative angular positions in each piece so that the passages in one piece may be coaxially aligned with the passages in the other said piece by establishing the correct relative radial orientation of the two pieces along their common axis, and keying means comprised in the respective pieces to cooperate in establishing the said correct relative orientation between said pieces.
Claim 2
Dependent Claim
94 words
A two-piece torch tip for a gas-fired torch, comprising, in combination, a gas mixer piece, a flame end piece, each said piece having a plurality of passages therethrough for gas, said passages having given relative angular positions in each piece so that the passages in one piece may be coaxially aligned with the passages in the other said piece by establishing the correct relative radial orientation of the two pieces along their common axis, and keying means comprised in the respective pieces to cooperate in establishing the said correct relative orientation between said pieces.
Claim 3
Dependent Claim
45 words
Apparatus in accordance with claim 1 in which the said passages have the same relative positions in both said pieces so that the passages in one piece may be coaxially aligned with the respective passages in the other piece by use of said keying means.
Claim 4
Dependent Claim
44 words
Apparatus in accordance with claim 1, in which said keying means comprises a noncircular cylindrical end portion on one of said pieces and in which the other said piece has a mating socket therein for receiving said end portion of the first said piece.
Claim 5
Dependent Claim
27 words
Apparatus in accordance with claim 3, in which said end portion of the first said piece is generally circular cylindrical in form with a flat surface portion.
Claim 6
Dependent Claim
16 words
Apparatus in accordance with claim 3, in which said socket is in the flame end piece.
Claim 7
Dependent Claim
22 words
Apparatus in accordance with claim 5, in which said socket is comprised in a third member attached to said flame end piece.
