GAS-REGULATING BURNER.

SPECIFICATION forming part of Letters Patent No. 396,258, dated January 15, 1889.

Application filed May 19, 1888. Serial No. 274,862. (No model.)

To all whom it may concern:

Be it known that I, HAROLD J. BELL, a citizen of the United States, residing at Gloucess ter, in the county of Camden and State of New Jersey, have invented new and useful Improvements in Gas-Regulating Burners, of which the'following is a specification.

This invention relates to a simple and effect ive governing device for gas-burners,whereby the quantity of gas admitted to the burner can be readily and accurately adjusted to the capacity of the burner and the pressure of gas automatically regulated without waste.

The invention consists in the construction and combination of parts, as hereinafter set forth and claimed.

In the annexed drawings, illustrating the invention, Figure 1 is a vertical section on the line y y of Fig. 2. Fig. 2 is a plan of the gas governor or regulator. Fig. 3 is a horizontal section on the line or 9;- of Fig. 1.

The numeral 1 designates a metallic shell provided at its lower end with internal screwthreads. 2 for engaging a gas-fixture. This shell 1 is divided about midway its length by a horizontal partition, 3, having a central perforation, l, to afford a passage for gas into the upper part of said shell. The upper portion of the shell 1 is of somewhat larger diameter than the lower part, and is provided at the top with a shoulder, 5, and internal screwthreads, (3, to engage an upper detachable portion or cap, 7, which is externally threaded or otherwise adapted to connect with a gasburner.

In the lower internally-threaded portion of the shell 1 is located an adjustable disk, 8, having perforations or gas-passages 9 and a screw-threaded periphery, whereby it can be screwed into place by means of any suitable instrument inserted into said perforations. This disk affords a vertically-adjustable support for a float-valve, 10, which consists of a disk or float, 11, and a central tubular stem, 12, having enlargements 13 and 14 at its opposite ends, thepurpose of which will be hereinafter explained.

The cap 7 is formed with an inner chamber, 15, consisting of a contracted upper part closed at the top and extended below the attaching portion of said cap and an expanded lower part open at the bottom and approaching the walls'of the upper part of the shell 1, within which it is inclosed. This chamber 15 affords a guideway for the float 11 and upper enlarged end, 13, of its tubular stem 12, as shown. Any leakage of gas around the float 11 finds an exit through a tube, 16, that leads from the expanded part of the chamber 15, as shown.

It will be seen by reference to Fig. 1 that the expanded part of thechamber 15 does not extend to the partition 3, and that around said chamber, between itand the shell 1, is an annular gas-passage, 17, which communicates with separate vertical gas-passages 18, Figs. 1 and 3, which are cored in the wall of the contracted upper portion of the chamber 15, between it and the outer portion of the cap 7, of which it forms part.

As shown in Fig. 1, the upper portion of the cap '7 is internally screw-threaded to receive a disk, 19, the periphery of which is threaded to engage therein. This disk 19 is provided with a central perforation, 20, forming a gaspassage, which is controlled by adjustable screws 21, that are located horizontally and end to end in said disk, as shown in Fig. 2, to regulate the quantity of gas admitted to the burner. The disk 19 is also provided 011 one side with a perforation for receiving the upper end of the tube 16, through which any accumulation of gas in the expanded or enlarged portion of the chamber 15 is discharged into the space above the disk 19, where the pressure is less than that below said disk. W hen the gas is turned off, the stem of the floatvalve 10 rests on and is supported by the perforated disk 8, which can be adjusted to any required height. hen gas is admitted into the lower end of the shell 1, it passes through 0 the perforations 9 and 4: into the upper part of said shell, thence through the vertical passages 18 into the upper part of the cap 7, and through the passage 20 to the burner. The

normal pressure of gas against the under side 5 of the disk-float 11 slightly raises said float and its hollow stem 12, so that a suflicient quantity of gas will pass through said stem into the upper contracted part of the chamber 15 above the enlarged upper end, 13, of the I00 float-stem, and there exert a counterbalancing pressure to prevent the further upward movement of the float-valve under ordinary gaspressure. Should the pressure of gas become excessive, however, it will so act on the float 11 as to cause said float and its stem to ascend farther and bring the enlargement or shoulder 14 on the lower end of the stem into closer proximity to the gas-passage 4, whereby said enlargement or shoulder 1-l is made to act as a valve to diminish the flow of gas, and consequently reduce its pressure in the upper part of the device. If the gas-pressure in the lower part of the shell is decreased, the float and valve will descend to permit a larger flow. The quantity of gas admitted to the burner is controlled by adjusting the screws 21 toward or from each other, so as to diminish or enlarge the gaspassage 20 to suit the capacity of the burner employed. This can be done from the outside of the device without detachingany part or extinguishing the light.

The location of the adj Listing-screws 21 in the cap 7 for the purpose of adjusting the quantity of gas to the capacity of the burner and the relative arrangement of the lower gaspassage 4, float 11, and valve 14, as shown and described, result in the production of a volumetric gas-governing device, in which the pressure is automatically regulated in an efficient and reliable manner.

lVhat I claim is 1. In a gas-governor or gas-regulating burner, the combination, with a shell having a partition, 3, provided with gas-passage 4, and a cap, 7, having a central chamber, 15, and separate vertical gas-passages 18, of a float-valve, 1.0, comprising a disk, 11, and a tubular stem, 12, carrying a valve, 14, substantially as described.

2. In a gas-governor or gas-regulating burner, the combination of the shell 1, having a partition, 3, provided with gas-passage 4, the cap 7, having chamber 15 and separate vertical gas-passages 18, the float-valve 10, the perforated disk 19, and the tube 16, leading from the chamber 15 and through the disk 19, substantially as described.

In a gas-governor or gas-regulatin g burner, the combination of the shell 1, having central gas-passage, 4, the disk 8, having perforations 9, the cap '7, having chamber 15 and separate vertical gas-passages 18, the float-valve 10, the disk 19, having gas-passage EZO and screws 21, controlling said passage, and the tube 16, leading from the chamber 15 and through said disk 19, substantially as described.

In testimony whereof I affix my signature in presence 05 two witnesses.
