JOHN soHornN', or NEWARK, OHIOl GAS ooox.

Application filed November 1, 1923. Serial No. 672,226.

To all who/m, t may concern:

Be it known that I, JOHN citizen of the United States, Newark, in the county of Licking and SoHornN, a residing at State of Ghio, have invented a new and useful Gras Cock, of which the following 1s a speciiication.

This invention aims to provide a gas cock for a burner for gas and other fuels of a like sort which is so constructed that it may be adjusted readily without the use of tools, the device being simple in construction and devoid of complicated parts, the construction being such that a. proper adjustment of the gas supply may be attained readily, the burner preventing a wasting of the fuel when operated properly.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

lVith the above and other objects in view, which will appear as the description prooeeds, the invention resides in the combination 'and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimec, changes in the precise embodiment of the invention shown can be made, without departing from the spirit of the invention.

In the drawings:

Figure 1 shows in side elevation, a device constructed in accordance with theinvention; Figure 2 is longitudinal section on the line 2-2 of Figure 1, parts remaining in elevation; Figure 3 is a cross section on the line 3-3 of Figure 1; Figure 4 is a fragmental longitudinal section showing a modification; Figure 5 is a cross section on the line 5-5 of Figure 4.

In ca rrying out the invention, as shown in Figures 1, 2 and 3, there is provided a main tubular member 1 terminating in a tip 2 carrying a projecting needle valve 3, the tip having inwardly converging passages 4, located about the valve 3 and merging into a single inlet opening 5 at their rear ends, the opening 5 communicating with the bore of the main member 1. The main member 1 is provided intermediate its ends and near to its rear end, with a wrench head 6 whereF by the rear end of the main member 1 may be threaded at 7 into the gas supply pipe 8, the head 6 abutting against the forward end of the pipe 8.

' dle valve 21 formed A A sleeve 9 is threaded at 10 on the member 1, for adjustment longitudinally thereof, and is supplied with a burner orifice 11 controlled by the needle valve. At its rear end, the sleeve 9 is equipped with a combined hand wheel and guard 12, whereby the sleeve may be rotated, the hand wheel including a disk like body 14 and a rearwardly extende peripheral liange 15 housing the wrench head 6.

When the parts are arranged as shown in Figure 2, the gas or the mixture of gas and air, or other fuel, flows from the pipe 8, through the main member 1, through the opening 5 and the passages 4, the air and gas, or other fuel, moving into the chamber 16 which exists betweeny the forward surface of the tip 2 and the rear surface of the forward end wall of the member 1, the fuel flowing about the pointed needle valve ,2, through the burner orice 11. By moving the sleeve 9 lengthwise of the member 1, through the instrumentality of the hand wheel 12, the needle valve 3 may be made to control the amount of gas passing through the orifice 11, and if desired, the flow of gas may be stopped entirely. The iange 15 of the lhand wheel 12,y houses the wrench head 6 and it will be impossible to turn the member 1 accidentally by way of the wrench head 6, and loosen the connection between the member 1 and the Apipe 8.

In Figures 4 and 5, the sleeve 17 is threaded at 18, as before onthe main member 19, the sleeve 18 having a tapered nozzle 2O adapted to Ycooperatev with a tapered neeon the forward end of the main member 19, the main member dis- .charging through lateral openings 22 formed in the tapered tothe rear of the needle valve. Aside from the modifications specified, the device depicted in Figures 4.and 5 is constructed like the device delineated in the other figures, and operates inA the same way.

In a device of the class described, a tubular member provided at its forward end with a reduced projection and supplied in its forward end with an opening communicating with the interior ofthe tubular member, the tubular Amember being supplied intere mediate its ends with an outstanding head, and being threaded externally both in front of the head and to the rear thereof, a sleeve threaded on the forward portion of the tubuportion of the 'memberf19, y

10 that,

lai1 memberand' having a combustion orifice controlled by the projection, the Sleeve being supplied at its rear end With a Wheel whereby the sleeve may be rotated, theY wheel embodying a rearwardly extended annular flange, the head being housed Within the flange of the Wheel against undesirable access, the periphery ofthe head being spaced suflieiently from the flange of the Wheel so through the instrumentality of the head, the rear portion of the tubular member may be threaded; intoY a support.

In testimony that I claim the foregoing as my oWn, I have hereto aHiXed my signature in the presence of tWo Witnesses.
