GAS-GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 400,170, dated March 26, 1889.

Application filed July 2, 1888. Serial No. 278,732: (No model.)

To all whom, it may concern.-

Be it known that I, HAROLD J. BELL, a citieen of the United States, residing at Gloucester City, in the county of Camden and State of New Jersey, have invented new and useful Improvements in Gas-Governors, of which the following is a specification.

My invention consists in a gas-governor-or gas-regulating burner having the peculiarities of construction hereinafter described and claimed.

In the annexed drawings, illustrating the invention, Figure 1 is a vertical section of a gasregulating burner embodying my improvement. Fig. 2 is an elevation of the lower part of the gas-regulating shell. Fig. 3 is a plan of the lower part of said shell. Fig. 4 is a perspective of the conical float-valve.

The numeral 1 designates the lower part of the regulator-shell, and 2 the upper part of the same, said parts being connected by screwthreads, so as to be readily separable-whenever required. As shown, the lower shell part, 1, has an internally-threaded neck, 3, for attachment to a gas-fixture. Surrounding the upper portion of the neck 3 is an annular flange, 4, which forms the floor of the main gas-regulating chamber or passage. Above the neck 3, in axial line therewith and communicating with its interior, is a short tubular stem, 5, which is surrounded by a cup or annular open-top chamber, 6, said stem and cup being integral with the lower part of the regulator-shell. The bottom of the cup 6 is elevated above the flanged portion 4 of the lower part, 1, to form an annular gas-passage, 7 ,within the upper part of the regulator-shell.

In the bottom of the cup 6 is an inclined opening or perforation, 8, for the passage of gas into the annular passage 7, and this opening 8 is controlled by an adjusting-screw, 9, passed diagonally through the flanged or enlarged portion of the lower shell part, 1, so that by moving the screw 9 inward or outward the quantity of gas admitted to the annular passage 7 can be regulated with great nicety.

Around the base of the tubular stem 5, within the cup 6, is an annular shoulder, 10. On the upper end of the tubular stem 5 is a laterally-projecting annular lip,- 11, and above the tubular stem 5, supported on legs 12, is a disk, 13, from which rises a central vertical guide, 14, for a hollow conical float-valve, 15, which surrounds said guide. The form of the hollow conical float-valve is illustrated in Fig. 4, in which the outer wall of the device is partly broken away to show its internalcon struction. The bottom or enlarged lower end of the conical float-valve 15 consists of a circular plate, 16, the edge or rim of which pro= jects sufficiently to very nearly fit within the cup or annular chamber 6, in which said floatvalve is adapted to rise and fall. The center of the plate 16 is perforated for the attachment of a short tube, 17, which projects upward and closely surrounds the lip 11 of the short tubular stem 5, through which gas is admitted to the regulator. The spaces or openings 18 between the legs 12 at the top of the hollow stem 5 form gas-passages, which are controlled by the tube 17, which thus acts as a valve to regulate the pressure of the gas. The gas that passes through the passages 18 into the hollow conical float 15 escapes therefrom through openings 19 in the bottom plate, 16, and enters the cup or chamber 6, whence it passes through the opening 8 into the annular gas-passage 7, and thence upward around the outside of the cup 6 and float 15 by the passage or passages 20 within the upper part of the shell to the burner. In orderto afford a clear passage for the gas the outside of the cup 6 is cut away at one or more places, 21, as shown in Figs. 2 and 3, and is screw-threaded for the remainder of its periphery to afford attachment for the upper part, 2, of the regulator-shell. The upper shell part, 2, rests on the lower part, 1, as shown, and supports at its upper end a perforated disk, 22, and an atmospheric gas-tube, 23, having lateral airinlets 24:; but it is obvious that the atmospheric gas-tube can be omitted, and any form of burner can be used either with or without said atmospheric tube.

The operation of the regulating devices will fully appear from the foregoing description in connection with the arrows in Fig. 1, indicating the course of the gas-currents. The hollow conical float-valve 15 is normally sup- 100 ported on the shoulder 10, so as to leave a clear passage for gas through the hollow stem 5, openings 18, hollow float 15, openings 19, cup 6, opening 8, and passages 7 and 20 to the burner. \Vhenever the pressure of gas within the hollow lioat 15 becomes excessive, said float will rise along the guide 11 and cause the tubular valve 17 to diminish the flow at the openings 18, thereby automatically regulating the pressure at the burner, while by means of the screw 0 the quantity of gas admitted to the burner can be controlled at will.

In concurrent applications, Serial Nos. 278,733 and 338,737, of even date herewith, I have shown gas-regulators comprising a twopart shell having an internal tubular perforated stem closed at its upper end. and provided with a guide for a flaring conical tloat which operates in a cup surrounding the base of said tubular perforated stem, the float being provided with an internal perforated tube to control the gas-openings of the stem, and an ad} Listing-screw being arranged to control the passage of gas through an opening in the bottom of the cup leading to a passage that con'nnunicates with the burner. The construction just referred to is claimed in my said application, Serial No. 278,737, while my invention as claimed herein is confined to a gas-regulator in which thehollow conical float is provided with a bottom plate, 16, having perforations 1!) and carrying a tubular upward-projeeting valve, 17, which is unperforated.

hat I claim is 1. In a gas-governor or gas-regulatin g burner, the combination, with the anl'iular chamber 6, having an outlet-opening, 8, and the tubular stem 5, having gas-passages l8, and guide 14, of the hollow conical float 15, having a bottom plate, 16, provided with perforations 19 and carrying a tubular up\wtrd-proj eetin g valve, 17, substantially as described.

:2. In. a gas-governor or gas-regulating burn er, the combination of the lower shell, 1,11aving a tubularstem, 5, provided with gas-exits, the guide 1-1, projecting above said stem, the annular chamber (i,having outlet-opening 8, the hollow conical float 15, having perij'orated bottom plate, 16, tubular valve 17, and gaspassages 19, the upper shell, 2, and the gaspassages 18 and 20 between said shells, substantially as described.

In testimony whereof I ailix mysignature in rcsence of two witnesses.
