CARI. J. NYQUIST, OF CHICAGO, ILLINOIS.
TORCH.
Application led November 18, 1918. Serial No. 263,004.
To all whom t may concer/n.:
' Be it known that I, CARL J. NYQUIST, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Torches, of which the following is a specification.
.My invention relates more particularly to a device for burning mixed gases, it having been devised for embodiment more especially in an Oxy-.acetylene gas torch of the general type forming the subject of my United States Letters Patent No. 1,248,895, granted December 4, 1917, wherein the torch is provided with a mixing chamber for the oxygen and acetylene, and with 'a flash-back pocket between the mixing chamber andthe nozzle of the torch and in communication with the mixed-gas conduit leading to the nozzle, in which Hash-back pocket mixed gas, during the ow of the latter through the conduit, collects, and in the 'event of backring of the flame combustion of the gases in the flash-back pocket is produced which blows out the flame in the burner.
.My primary object is to provide a novel, simple and inexpensive construction of torch of the general character above stated and one which may be economically constructed not only in the sizes of torches as commonly provided, 'but also of such size as to be particularly adaptable for use by women operators.
Referring to theaccompanying drawing; Figure 1 is a view in side elevation of a torch embodying my invention; Fig. 2 is an enlarged view in sectional elevation of the right-hand end of the torch-in Fig. 1; vand Fig. 3, a: longitudinal sectional view of the nozzle-portion of the torch.
In the particular construction illustrated, the body portion of the torch and which is the part grasped lby the operator in using the torch, is formed of a casting 4 of general cylindrical form with a lateral extension 5 thereon. The left-hand end of the body member 4 in Fig. 2 contains a socket 6, the inner portion of which is threaded as indicated at 7 and its outer portion unthreaded as represented at 8, the socket thus provided opening into one end of a p-assage 9, which communicates at 'its opposite end with a threaded socket 10 in the body 4, the extension 5 of the body also containing a passage 11 which opens at one end into a threaded socket portion 12 in this extension and at its opposite end into the socket 6. I'lhesockets Specification of Letters Patent.
10 and 11 are adapted to have screwed therein pipe sections 13 and 14, respectively, provided with valves 15 and adapted to be connected, respectively, with the sources of gas, as for example, oxygen and acetylene, to be mixed in the burner and thereafter ignited at the nozzle of the latter.
The socket 6 contains a tubular member 16 which screws at its inner, threaded portion 17 into the threaded inner portion ofthe socket 6, the portion of this member toward its outer end being unthreaded whereJ it opposes the unthreaded portion 8 of the socket 6, the member -16 being formed with a shouldered portion 18 at which it abuts against the end of the body member 4. The member 16 is longitudinally bored from end to end to afford a passage therethrough, preferably of varying diameters as represented at 19, 20, 21 and 22, the section 19 vof the -bore opening into the innermost end of the socket 6 and in communication'with the passage 9.. The periphery of the member 16 is annularly grooved, as represented at 23. and 24, these grooves being spaced apart by a relatively long length of material, prefer- 4ably threaded as shown, and as vrepresented in Fig. 2, the groove 24 registering with the gas passage 11 through the medium of branch-passages 25 converging toward the front end of the torch and opening into the bore 21; and theannular groove 23 registering with the bore 21 through the medium of alforwardly extending inclined passage 26.
The forward end of the member 16 is connected with one end of a stem 27 which its into the bore 22 of the member 16 and is held thereon as by a clamp nut 28 embracing a shouldered portion 29 of the stem and screwing upon the outer, reduced and threaded end portion 30 of the member 16, the stem 27 being provided at its outer end with a nozzle 31 in communication with the bore 21 through the medium of the opening extendin lengthwise through the stem 2 n the use' of the torch, assuming it to be used with oxygen and acetylene, the oxygen passes from the pipe 13, through the bore 9 and the bore in the member 16,-wherein it becomes mixed with acetylene passing from ratend'May 2o, 1919.
the pipe 14 through the passage l1 and `which it discharges, the gas being burned at the nozzle. The mixed gas also fills the pocket 23 which forms the flash-back pocket, wherein combustion of the gas takes place and blows out the iame in the burner, in the event Aof back-firing of the ame in the burner.
What I regard as new and desire to secure by Letters 4Patent is-` l. A torch comprising a tubular member containing a socket for communication with a plurality of gas supplies, and a second member confined in said socket and containing a conduit extending therethrough for communication with one of said gas supplies, said second member containing passages in its periphery, one of which forms a flash-back pocket in communication with the conduit in said second member and the other of which communicates with said con-` duit and opens into that part of said socket which communicates with the other of said gas supplies.
2. A torch comprising a tubular member containing a socket for communication with a plurality of gas supplies, and a second member confined in said socket and containing a conduit extending therethrough for communication with one or" said gas supplies, said second member containing passages in its periphery spaced apart lengthwise of said member, one of said passages forming a flash-back pocket in communication with the conduit in said second member, and the other of said passages communicating with said conduit and opening into that part of said socket which comnunicates with the other of said `gas supp ies.
3. A torch comprising a tubular member containing a socket for communication with a plurality of gas supplies, and a second member coniined in said socket and containing a conduit extending therethrough for communication with one of said gas supplies, said second member containing annular passages in its periphery spaced apart lengthwise of said member, one of said passages forming a flash-back pocket in communication with the conduit in said second member and the other of said passages communicating with said conduit and opening into that part of said socket which communicates with the other of said gas supplies. v
s. A torch comprising a tubular member containing a threaded socket for communication with a plurality of gas supplies, and a second, threaded, member screwed into the threaded portion of said socket and containing a conduit extending therethrough for communication with one of saidgas supplies, said second member containing passages in its periphery, said passages being spaced apart lengthwise of said member, with a section of the threaded portion of said member interposed therebetween, one of said passages forming a Hash-back pocket in communication with the conduit in said second member and the other of said passages communicating with said conduit and opening into that part of said socket which communicates with the other of said gas supplies.
5a. A torch comprising an integral body member containing a socket with passages for communication with gas supplies, opening into said socket4 at different points along its length, and a second member confined in said socket and containing a conduit extending therethrough and communicating with one of said passages, said second member containing passages in its periphery, one of which forms a ash-back pocket in communication with the conduit in said second member and the other of which communicates with said conduit and opens into that part of said-socket which communicates with the other of said passages in said body member.
6. A torch comprising a tubular member containing a threaded socket for communication witha plurality of gas supplies, and a second, threaded, member, screwed lilnto the threaded portion of said socket and cony taining a conduit extending therethrough for communication with one of said gas supplies, said second member containing annular passages in its periphery, said passages being spaced apart lengthwise of said member, with a section of the threaded portion of said member interposed there-between and one of said passages forming a flash-back pocket in communication with the conduit in said second member and the other of said passages communicating with said conduit and opening into that part of said socket which communicates with'the other of said gas supplies.
