The said underwater torch .iscomprised essentially of a main body I, astraight head 2,.a goosenecli 3., a torch tip t, and a torch "tip shield 5.
The inlet valve 6 at its outer end is attached to the acetylene. or hydrogen line, and at its in,- ner end joins the valve, 1, which controls the said gases. Thevalve lconneots with theapassage 2.5, and the tube .21 (Fig. 5) which is secured in the body portion "I l, and entersthe receptacle 28 of the straight head'Z. r I v I Between valves 6 and I is the by-passt, leading to valve '9,"whi ch regulates't'he flow of gases to the pilot lightand leads to the 'recepta'cle'23 of the straight head 2; fl v The inlet valve ill at its outer end is attached to the oxygen line and at its inner end connects to'the'body portion "H, housing the high pressure valve I1, which controls the flow of the oxygen during the cutting process. "The high pressure lever It operates the said high pressure valve 12.
The inner 'end of the valve 'Hl :iscommunicating through the -high pressure valve 12 (see Fig. 5) with the tube 33 and the receptacle 25 of the straightheadi; g l I The valve It controls-the oxygen to the preheatingflame-y The inlet valve It at its outer end connects'to the hydrogen line when-the inlet valve 5 is used for acetylene. -At its inner .end it connects to the The outlet 20 is secured to the inner end of the V valve 2| and leads to the receptacle 24.
The by-pass 22 enters the body portion ll between the valves l and I2 and is leading to the outer end of the valve 2! which at its inner end is connectedto the receptacle 24 of the-straight head 2.
The tube 29 is within the tube 21 and is secured in the body portion II. from the inner end of the valve H] to the control valve I4 and leads to the tube 29 with the mixer 3| suitably placed at its interior adjacent to its outlet, insuring a whirling motion to the gaseous mixture in the mixing chamber 34 which communicates with the receptacle 28 of the,
The by-pass 30 leads chamber 34 from overheating in case of back flash.
The loop 51 holds securely together the various outlets and tubes.
THE OPERATION or THE TORCH Two line method-Without pilot light Assuming the use of the torch in shallow water by the two line method, using acetylene and oxygen, the tanks containing these gases are connected to the regulators and the hose from v the regulator for the acetylene supply is con- The straight head 2 consists of a cylindrical body. At its near end 32 it is provided with the receptacles 23, 24, and 28 to secure the outlets 11,20 and the tubes 33, 21, respectively.
The suitable interior portion 35 of the straight head 2 is provided with a series of passages.
The passages 36 leading from the bottom of the receptacle 28 to the level 31 are conducting the mixed oxygen and gas. The passage 38' leading from the bottom of the receptacle 25 to the level 39- is conducting the oxygen for cutting purposes. The passages 40 leading from the bottom of the receptacle 24 to the level 4i are conducting the oxygen or compressed air. The passages 42 leading from the bottom of the receptacle 23 'to the level 43 are conducting the acetylene or hydrogen for the pilot light. The use 01 hydrogen, or other suitable gases, prevents corrosion and accumulation of carbon at the opening of the pilot light which would set in when acetylene is used.
The suitable interior portion 44 of the rotatable gooseneck 3 is provided with the continuation of the'passagei 3B, 38, 40 and 42. V
The adapter 45 is provided with R. H. and LLI-I. threads, permitting the gooseneck 3 to rotate freely around the straight head 2 by means of themain body I being adapted to take any desired position" for the convenience of the'diver in using the high pressure lever l3.
The adapter 46 secures the torch tip 4 to the gooseneck B.
The suitable torch tip 4 is provided with four levels, corresponding to the levels. of 39, 31, 4! and 43 of the straight head 2, and-with the continuation of the passages 36, 38, 40 and 42. a
The torch-tip 4 'is provided with an externally threaded cylindrical portion 41 which retains the adjustable shield 5 at its set position.
The suitable interior 48 of the shield 5 is provided with a cylindrical portion 49 and an ofiset 50 at its lower end by means of which it can rest adjustably 'on the externally threaded portion' 41 of the torch tip 4.
washers 5| are securely held downby the cylindrical portion 49 of the shield 5.
"The suitable interior cylindrical portion 52 of the shield 5 has an offset 53. The conical portion 54, between the offsets 50 and 53, is provided with fine threads 55 to induce a whirling motion to the oxygen or compressed air before passing through the said cylindrical portion 52 and reaching the work. The knurled indentat'i'cins 55 permit the gases generated during the cutting process to escape. g
The perforated handle 55 preventsthe mixing nected to the valve 6 while the hose leading from the regulator for the oxygen supply is connected to the valve Ill, the regulators being adjusted to suit the work being done. The acetylene valve' are adjusted to give the proper mixture for the pre-heating flame.
If the torch is to be used by the two line method with hydrogen instead of acetylene, as when operating in deep water, the operation is the same except the hydrogen supply, instead of the acetylene supply, is connected to the valve 6.
When using the two line method, the bypasses which have been provided serve the purpose of displacing the water and holding it away from the mouth of the torch tip. The by-pass 22, which serves that purpose, starts between the valves l0 and I2 and conducts the gas through the valve 2! to the outlet 20 which leads into thereceptacle 24. From this receptacle the gas passes through the passage 40 and impinges against the offset 50 of the upper inner cylindrical portion of the shield 5. The oxygen then passes downwardly in contact with the threaded portion 54 of the shield by which it is given a whirling'motion before it reaches the lower cylin drical portion 52 of the shield. By adjusting the valve 2| the supply of oxygen may be regulated to displace the water from the torch tip.
I v Three line method-With pilot light If the three line" method is to be used with a pilot light. the operation is the same as that Four line method-With pilot light In. practicing the "four line method of operation of the torch with a pilot light, the procedure is the same as when using the threeline with pilot light, except that thevalves 9 and 2| are closed and an oxygen supply isconnectcd through a regulator to the inlet valve H! which conducts the oxygen through the-by-p'ass I! into the outlet 20 byzwhich it is conveyed to the receptacle 24. From this receptacle, the gas passes through the passage 40 to the onset 50 of theupper interior part of the shield 5, from which it passes in contact with the threaded portion M- to the offset BI and then outwardly through the cylindrical portion 52. If compressed air is to be used to displace the water, instead of oxygen, the compressed air supplyisconnected to the valve I! in place of the oxygen connection.
It will be understood thatv the invention may taltevarious formsother thanthat'herein speci-iically describedwithout departingfrom the scope or the appended claims in which the term "gas isused generically as reierring'to compressed air, oxygen, acetylene or hydrogen. The term integral as used in the claimshas its'usual mean-' ing as defining a one-piece unitary structure". Where reference is made in the claims to" a passage through the tip for conveying oxygen or the like to the annular passage between the tip andthe shield, it will be understood that the term "oxygenf is intended to include oxygen, compressed air, or other combustion supporting gaseous fluid which may be introduced through this passage.
