GAS-GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 400,173, dated March 26, 1889. Application filed July 2, 1888. Serial No. 278,736. (No model.)

To all whom it may concern.-

Be it known that I, HAROLD .I. BELL, a citizen of the United States, residing at Gloucester City, in the county of Camden and State of New Jersey, haveinvented 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 of the construction hereinafter described and claimed.

In the annexed drawings, Figure 1 is a vertical section of a portion of a gas-regulating burner illustrating my invention. Fig. 2 is an elevation of the base and inner portion of the gas-governing device. Fig. 3 is a horizontal section on the line 00 o: of Fig. 2. Fig. 4 is a perspective of the float-valve.

The numeral 1 designates the base of the gas-governing device, and 2 the shell which forms the casing and supports the burner.

The base 1 is formed with an internally-screwthreaded neck, 3, for attachment to a gasfiXture,and with an externally-sorew-threaded shoulder, 4, that engages internal threads in the lower end of the shell or casing.

Above the neck 3, and communicating therewith, is a tubular stem, 5, having a series of lateral gas-exits, 6, that are located in an annular countersink, 7, about midway the height of said stem. The tubular stem 5 is closed at the top.

Surrounding the tubular stem 5 is a tubular valve, 8, the lower end of which normally rests on the flat upper surface of the base.

The upper portion of this tubular valve is provided with lateral openings 9, that correspond with the lateral gas-exits 6 of the tubular stem 5, and immediately above these open ings 9 is a disk-float, 10, that is attached to or formed on the valve. .It will be seen that both ends of the tubular valve Sare open. The periphery of the disk-float 1O approaches but does not touch the vertical wall of the shell 2, an annular gas-passage, 11, being left 5 between the disk and the casing or shell. This casing or shell is cylindrical in form and has a nipple or pillar, 12, for the attachment of any suitable burner. The gas that enters the tubular stem 5 passes out through the openings 6 and 9 into the shell 2 beneath the disk-float 10, and then upward around the periphery of said float to the upper part of the shellor casing and onto the burner. If the pressure of gas in the shell 2 is very great, it will cause the float l0 and Valve 8 to rise, thereby diminishing the flow of gas at the openings 6 and 0 and regulating the pressure at the burner.

It will be observed that no matter what lateral position the tube 8 may assume on the tubular stem 5 the annular countersink or groove 7, formed in said stem, will prevent any obstruction to the flow of gas through the openings 6 and 9, which might otherwise occur by a partial rotation of the tubular valve.

In another application, Serial No. 278,735, of even date herewith, I have described and claimed a gas-regulator having atubular perforated stem closed at its upper end and surrounded by a tubular open-ended valve provided with lateral vperforations and carrying a disk-float that operates in an annular opentop chamber or cup surrounding the tubular perforated stein, a gas-passage being provided I through the lower part of said cup, which gas 7 5 passage is controlled by an adjusting-screw located in the base of the regulator. In my present invention the cup and adjusting screw are dispensed with, and the disk-float 10 is fitted with sufficient looseness in its sur- 8o rounding shell or case to afford an annular passage, 11, for the exit of gas to the burner.

I am aware that a gas-valve has heretofore comprised a laterally-perforated tube closed at its upper end by a disk-float; but this I do not claim.

In applications Serial Nos. 27 8,7 32, 27 8,7 33, and 278,737, of even date herewith, I have shown gas regulators comprising a two-part shell having an internal tubular laterally-per- 9o forated stem closed at its upper end and pro vided with a guide for a flaring conical float, which operates in a cup surrounding the base of said tubular stem,the float being provided with an internal tubular valve to control the gas-openings of the stem. In each of the above-mentioned applications the float-valve is shown with a lower flaring end, which fits somewhat closely in the surrounding cup without binding therein, and a gas-passage to the burner is all'orded through an opening in the bottom of the enp, which is controlled by an adjnstingserew in the base of the regulator. In an ap iilieation Serial No. 278,7;3-l, of even date herewith, l have shown a construetion in which the canitrollable gas-passage through the bottom oi? the eupisomitted,and the eonieal float-valve titled loosely in the cup in such a manner as to provide an annular gas-passage between the cup and valve. By my present invention l. dispense with the cup and the eonieal valve-float, and I attach to the tubular valve a dislelloat, wliieh tits loosely within the upper part of the regulator-shell, thereby ailfording an annular gaspassage between said disk and shell. This construction differs from that described in my application Serial No. 278,735 tieulars hereinbel'ore explained.

I would have it nnderstomfl that [do not in the parbroadly claim a gas-governor having a t-ubular perforated valve provided with a disklloat; but

'hat I claim. as my invention In a gas-governoror gas-regulatingburner, the combination of the base 1, having a tubular stem, 5, closed at the top and provided with lateral gas-exits (5, located in an annular countersink, 7, the upper shell, 2, and the tubular valve 3, having lateral openings 9 and provided with a disk'lloat, 10, fitting loosely in the surrounding shell, an annular gas-passage, 11, being provided between said float and shell, substantially as described.

In testimony whereof I at'lix my signature in presence of two witnesses.
