Specification of Letters Patent.

Patented Sept. 26, 1916.

Application filed April 5, 1916. serial No. 89,140.

To all whom it may concern:

Be it known that I, GREEN B. \VILsoN, a citizen of the United States, residing at Nevada, in the county of Story and State of Iowa, have invented a new and useful Cooled Blowpipe or Torch, of which the following is a specification.

The present invention appertains to blowpipes and torches, such as use acetylene gas mixed with oxygen, and it is'the object of the invention to provide novel and improved means for cooling the blowpipe or torch, and especially the tip thereof, to prevent the excessive heating of the device which is objectionable for obvious and well known reasons.

The present invention embodies a fluid circulating chamber inclosing the blowpipe or torch and extending. to the tip thereof, whereby water, air or other suitable fluid can be circulated through said chamber to produce the desired cooling effect.

It is also within the scope of the invention to provide a cooled blowpipe or torch which is comparatively simple, compact and inexpensive in construction, as well as being thoroughly practical, efficient and reliable 1n use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure l is a longitudinal section of the improved structure, portions being broken away and others being shown in elevation.

Fig. 2 is an enlarged cross section on the line 22 of Fig. 1. Fig. 3 is a longitudinal section of a modified form of tip, and Flg. 41s an end view thereof. Fig. 5 istubular member 6 is welded 'or otherwise attached to the other end of the chamber 1 to provide a fluid circulating chamber.

There is a partition-7 between the chamber 1 and barrel 6, andsaid partition is provided with a nipple 8 pro ecting into said chamber, and provided at one side with a gas port or aperture 9. gas tube or pipe 10 is disposed concentrically within the barrel 6 and has one end threaded or otherwise engaged within the nipple 8, so as to communicate with the chamber 1 by way of the aperture 9, and an oxygen tube 11 extends through the tube 10, the nipple 8, and

the chamber 1, and is attached to the nipple 4 for the connection of the oxygen hose. The gas hose is connected to the nipple 3 to supply the acetylene or other gas into the chambe 1. The outer or forward end of the tube 11 projects out of the corresponding end of the tube 10, and the said end of the tube 10 is contracted and weldedor otherwise secured, as at 12, to the tube 11. The tube 11 is provided with one or more apertures 13 adjacent the forward endof the tube 10, so that the gas can flow into the tube 11 by way of the apertures 13, thereby providing the mixture which supports the needle flame.

. ater, air or other suitable cooling fluid is supplied into the barrel 6 by means of atube or pipe 15 extending through the barrel- 6 and chamber 1 and connected at one end with the nipple, 5, and the fluid is-conducted out of the basal or butt end of the barrel 6 by means-of a tube or pipe 14 having one 16, whereby the fresh inflowing fluid will be-supplied directly adjacent the tip, where the cooling effect is most needed. The member 16 has an outturned flange 17 resting against the end of the barrel 6, and a union 18 is threaded upon the end of the barrel 6 and has a. flange 19' overlapping the flange 17, whereby the -member 16 is clamped in fluid tight engagement against the barrel. The member 16 has a tubular portion 20 projecting inwardly from its apex and welded or otherwise secured, as at 21, .to the end of the tube 11.

The tip 22 has a nipple 23 threaded or otherwise removably engaged within the tubular portion 20, to provide the jet, various tips being used interchangeably, and the tips can be removed from and applied tothe member 16 without the necessity of detaching or interfering with any of the other parts.

Figs. 3, 4, 5 and 6 illustrate different forms of tips, for providing two jets. The tip 22 illustrated in- Figs. 3 and 4 has a pair of branches or outlet apertures 2a. The tip 22 illustrated in Figs. 5 and 6 is chambered, and has a pair of outlet apertures '25. With these tips, a double jet is provided, and the apertures of the tips may be spaced diflerent distances apart. The two-jet tip is of advantage, since two parts which are spaced apart can be heated simultaneously, prior to .welding.

The blowpipe or torch is used in the ordinary manner for welding or similar purposes, and the cooling fluid in being supplied through the tube or pipe 15 will be directed from said tube into the tip member 16, there by cooling the tip in the most effective manner. From the tip, the water flows backwardly through thebarrel 6, cooling the parts inclosed thereby, and flowing out by way of the tube 14. 'By using the cooling means, the blowpipe or torch can be handled more con veniently, the same being-kept cool, and this also eliminates the tendency for the parts to warp or otherwise become distorted.-

The present device can be used as a blow I pipe, welding torch, cutting torch, or for kindred other purposes. When a multiple flame tip is used, the volume of heat is increased materially without an appreciable lengthening of the flame. Any suitable number of outlet apertures can be used, and with the multiple jet tip, the greatest amount of heat can be applied to the points where most needed/ Having thus described the invention, 'what is claimed as new is:

1. A device of the character described,

embodying a fluid circulating barrel, a hollow tip member attached to one end thereof,

a blowpipe inclosed within the barrel and connected to said member, thev other end of the barrel having a fluid-outlet,- and a fluid supply pipe entering the last mentioned endof the barrel and extending to a point within said member.

2. A device of the character described, em-- bodying a gas chamber having four hose ating through the aforesaid tube and connected to another hose attaching portion and to the tip member, the oxygentube having an aperture communicating with the-first mentioned tube, ,a fluid outlet tubev engaged through said partition land connected to another hose attachingportion, and a fluid supplying tube connected to the fourth hose attaching portion, extending through said partition and within the barrel to a point adjacent said tip member.

3. A device of the character described, embodying a chamber having four hose attaching nipples, one for supplying gas into said chamber, a barrel having one end attached to said chamber, a tip memberatta'ched to the other end of said barrel, there being a partition between said chamber and barrel having a nipple projectlng into said chamber and provided at one side with an aperture, a gas tube having one end engaged within the last mentioned nipple,.an oxygen tube extendingthrough the gastube, last mentioned nipple, and chamber, and connected to another of the first mentioned nipples, the oxygen tube being connected to the tip member, the respective end of the gas oxygen tube having an aperture within the gas tube, a fluid discharge tube engaged through said partition and connected to another of the-first mentioned nipples, and a fluid supplying tube connectedtol the fourth of the first mentioned nipples and extending through said chamber, partition and within the barrel and terminatmg adjacent said tip member. Y

In testimony that I claim the foregoing as my own, I have hereto aiiixed my signature in the presence of two witnesses.
