FREDERICK W. MAGEE, OF LONDON, ONTARIO, CANADA, ASSIGNOR OF ONE-HALF TO THOMAS W. BAKER, OF LONDON, CANADA.

REGULATOR FOR GAS-STOVES.

To all whom it may concern:

Be it known that I, FREDERICK W. Mncnn, a subject of the King of Great Britain, and a resident of the city of London, in the county of Middlesex, in the Province of Ontario, Canada, have invented a new and useful Regulator for Gas-Stoves, of which the following is a specification.

This invention relates to a device for regulating the quantity and for regulating the velocity or the speed and flow of said quantity of gas. And it consists of the improved construction and novel combination of parts of the same as will be hereinafter first fully set forth and described and then pointed out in the claims.

In describing the invention in detail, reference is had to the accompanying drawings wherein like reference characters denote corresponding parts throughout the several views and in which:

Figure 1 is a side elevation of a gas regulator in accordance with this invention, and, Fig. 2 is a sectional plan, the valves being disposed on the side of the body-portion of the regulator opposite to that shown in Fig. 1.

Referring to the drawings by reference characters, 1 indicates a gas supply pipe adapted to communicate with the gas supply and 2 a cut-off valve having its casing com municating with the pipe 1 and its valve stem provided with a handle a. The valve casing is indicated by the reference character 2 and is provided with a laterally-projecting exteriorly-threaded nipple 2 The reference character 3 indicates the body-portion of the regulator and which is formed at one end with a laterally-extending interiorly threaded nipple 3 which is mounted upon and connected to the nipple 2 of the valve casing 2. The body-portion 3 is provided with a main gas passage 4 which is of less diameter than the inner diameter of the nipple 3 The nipple 2 is hollow whereby communication is established between the gas passage 4 and the supply pipe 1 when the valve 2 is opened. The outer end of thegas passage 4 is closed by a disk 5 which is fixedly secured to the body-portion 3 and is formed with a centrally-disposed gas outlet 6. The wall of the passage 4 in proximity to its inner end is provided with a valve seat 4* against which is adapted to engage the inner end of a.

valvular member 7 adjustably mounted in the body-portion 3 and which is adapted to extend across the passage 4. The function of the valvular member 7 is to open or close more or less the passage 4 for the purpose of regulating the quantity of gas passing through the said passage 4.

The body-portion 3 is provided with a supplemental gas passage 8, which is closed at its inner end and is of less length than the main passage 4. Communication is established between the passages 4 and 8 through the medium of a port 11 formed in the body 3. The port 11 is closed through the medium of a controlling valve 12 which is mounted in the body-portion 3. Arranged in alinement with the body-portion 3 but spaced therefrom is a mixing tube 10 and projecting in and opening into said tube 10 is a pipe 9 which communicates with the pas sage 8. The function of the pipe 9 is to conduct the gas from the passage 8 to the mixing tube 10. And this pipe 9 is necessary to convey this gas from the supplemental gas passage 8 to the mixing chamber 10, be cause the gas has not enough velocity of itself to pass from the supplemental gas passage 8 to said mixing chamber, otherwise this gas having no velocity would escape in the air and create an odor.

The object of permitting the gas to pass through the gas passage 11, from the main gas passage 4 to the supplemental gas passage 8, is for the purpose of regulating the velocity or the speed and flow of the gas through the opening 6 in the disk 5.

There is only one speed at which the gas of a standard richness will thoroughly incorporate and mix with the air, and prevent a back flash, and the sizes of the main gas passage 4 and the opening 6 in the disk 5 are adapted to gas of the lowest pressure and standard richness at which it can be commercially used and successfully burned. It is essential that the disk 5 be provided with a single opening for the passage of the gas for the reason that if the disk was provided with a plurality of openings for the passage of the gas, the velocity of the latter would not be-such as to draw in suflicient air in the mixing chamber or tube for combustion. In this case the device is made to work from gas of a low pressure to that of a high pressure, with standard richness, and the gas is always at the proper pressure when passing from the opening 6 in the disk 5 into the mixing chamber 10, irrespective of the pressure in the ipe 1.

While the gas goes t rough a single opening 6 in the disk 5 it does notvform a core of.

gas in the center of the mixing chamber or bunsen tube 10, because it passes out of the disk 5 at a speed at which it willbecome thoroughly incorporated or mixed with air. Gases vary in richness or in the amount of carbon they contain, requiring more or less air for satisfactory combustion, the velocity or speed of the gas or its passage to the mix ing tube or chamber sucking in the air for combustion. Therefore, the velocity or speed of the gas should be regulated and by this device it enables the velocity or speed to be easily and instantly regulated to increase the velocity or speed and flow. of the gas to draw in the required amount of air without interfering with the valve 7 which regulates the quantity of gas used.

By adjusting the valve 12 from the gas passage 11 the velocity of the gas through the opening 6 is reduced because a greater amount of gas passes into the supplemental" gas passage 8 consequently the pressure of the gas in the main gas passa e 4, and on the opening 6 is reduced, again loy adjusting the valve 12 toward the gas passage 11 the velocity of the gas through the opening 6 is increased because a less amount of gas passes into the supplemental gas passage 8 consequently the pressure of the gas in the main gas passage 4 and on the opening 6 is increased.

When the valves 7 and 12 are once set they remain so, unless the pressure or nature of the gas changes.

The valve 7 is the same diameter as the main gas passage A while the valve 12 which goes through themain gas passage 4 and governs the gas passage 11 is of less diameter than the main gas passage 4, this valve 12 therefore does not interfere with the passage of the gas through the main gas passage t. And the supply of gas from the pipe 1 to this device for every day use, is shut off or turned on by the valve 2. When so arranged, by adjusting the valve 12 to permit the gas to pass through the gas passage 11, the excessive pressure of the gas in the main gas passage 4 is reduced to the proper velocity or speed to. permit the gas passing out through the opening 6 to become thoroughly incorporated with the air in the mixing chamber 10. So that with this device the gas is taken at the lowest pressure that it will draw in suflicient air to thoroughly incorporate and mix with said air in said .mixing chamber or Bunsen tube, and any gas of a higher pressure is reduced, or the velocity or speed and How of said gas is reduced by means of said valve 12 and gas passage 11, and this prevents any back flash or other noise when lighting or turning out, and entirely doing away with an air shutter, at the same time a device is provided which is simple, strong, and durable in construction and efficient in practical use.
