ACETYLENE 'roncn.
\ Application filed Apri1 4,
The object of my invention is to produce a gas torch by means of which a highly explosive gas, such for instance as acetylene, may be safely combined with oxygen to safely produce a high temperature flame, the construction being such that the flow of gases may be readily controlled by the hand 111 which the main body of the torch is supported.
The accompanying drawings illustrate my invention.
Fig. 1 isa plan of a torch embodymg my invention, in position in an operating hand; Fig. 2 is an axial section.
In the drawing 10 indicates a main body having a delivery bore 11 and a surrounding threaded portion 12 to which any desired nozzle 13 may be attached in the usual well known manner. Axially communicating with the inner end of bore 11 is a threaded bore 14 in which is mounted a sleeve 15, the main body of which lies withinchamber 16 formed in body 10 co-axial with bores 11 and 14. The outer end of chamber 16 is threaded at 17 to receive the delivery end of a tube 18 having at one end a chamber 19 which embraces one end of sleeve 15.
Within the main body of tube 18 is a chamber 20, communicating throu h a restricted threaded bore 21, with charm r 19, and in this chamber 20 I mount a mass of aluminum chips 22, or other material, to form a foraminous mass 23 held in place by screens 24, 24.
Threaded in bore 21 is a nozzle 25 the delivery end of which is externally tapered and provided with a very small bore and projected into the internally tapered bore of sleeve 15, the space between nozzle 25 and sleeve 15 being comparatively small.
Threaded into the receiving end of chamber 20 is the main body of a controlling valve 30 the valve stem of which is provided with an operating head 31. i
Arranged alongside of chamber 16, in body 10, is a.threaded bore 32 connected by passages 33 and 33' with chamber 16 beyond the inner end of the adjacent end of tube 18.' Passage 33 is formed at a sharp angle to passage 32 and passage 33 is at a sharp angle to passage 33 and chamber 16 so that the op posite wall of passage 33 will offer a distinct obstruction to any sudden backward movements of gases through passage 33'. Passage 33 enters chamber 16 well away from the open end of tube 15 so that the com- 1925. Serial No. 20,683.
munication between bore 11 and bore 32'is an exceedingly tortuous one.
Mounted in bore 32 is the main body 34 of a controlling valve the stem of which is provided with an operating head 35.
Attached to the body of valve 34 is a tube 36 forming a chamber within which is mounted a foraminous mass, such as aluminum chips 37, retained'in place by screens 38, 38. The receiving end of tube 36 is threaded at 39 to receive a coupling 40 by which the oxygen hose 41 may be attached.
The gas supply hose 42 may be attached by a suitable coupling to the end 43 of valve body metacar a1 and the first thumb phalan e respective y, the parts being so positione that the operator may, without loosening his grasp uponthe tubes 18 and 36, easily roll the knurled heads of the valves in either direction to adjust the flow of gases.
The acetylene gas is delivered from nozzle 25 and immediately surrounded by an envelope of oxygen which is delivered through the tortuous passage formed within chamber 16 by tube 15 and nozzle 25, the arrangement being such that the quantity of explosive mixture formed thereby is at all times exceedingly minute and confined so as to eliminate the possibility of back firing. Where a more vigorous flame at the tip of the torch is desired I find that very satisfactory results may be obtained by connecting the oxygen to valve 30 and introducing the fuel gas through pipe 41.
. Ordinarily a reversal of the gases cannot be safely accomplished but is possible in my construction apparently owing to the sharply tortuous character of passages 33 and 33 and the fact that passage 33' enters chamber 16 at a point well away from the open end of tube 15 and is thus rotected'b the restricted passage between tlie wall of c amber 19 and tube 15.
I claim as my invention:
'A gas tor h comprising a main body formed at one end to receive the nozzle, said main body having, at its opposite end, a bore in which is mounted a central tube the bore of which communicates with the nozzle-receiving end of the main body and which tube bore at its opposite end is outwardly flared, a valved gas connection carried by'said main body having a passage extending at a sharp angle to said main body bore and communieating therewith at a point remote from the inlet end of said tube and having a second passage extending at substantially, right angles to said first passage and communicating therewith, a valved gas supply tube attached to the main body and having a tapered end projected into the flared end of the bore of the central tube of the main body, the arrangement being such as to insure forward movement of the gases throughout the tortuous passages, substantially as described. In witness whereof, I have hereunto set my hand at Indianapolis, Indiana, this 31st day of March, A. D. one thousand nine hundred and twenty-five.
