GAS-REGULATO R.

SPECIFICATION forming part of Letters Patent No. 340,112, dated April 20, 1896.

Application filed January 1R, 1886. Serial No. 188,962.

To all whom, it may concern.-

Be it known that I, HENRY H. GRIDLEY, a citizen of the United States, residing at Holyoke, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Gas-Regulators, of which the following is a specification.

This invention relates to improvements in gas-regulators; and the invention consists'in the peculiar construction and arrangement of parts, as hereinafter fully described, and pointed outin the claims, the object being to simplify and reduce the number of the parts in such machines, whereby their efficiency is increased and the necessity of frequent repairs is obviated.

In the drawings forming part of this specitication, Figure 1 illustrates in a vertical sectional view a gas-governor embodying my irnprovements. Fig. 2 is a transif'erse section of the valve-case. Fig. 3 is a transverse section of the valve-cage and the valve-spindle above the valve in Fig. 1, showing the upper end of the latter in plan view.

In the drawings, h is thc valve-case, having a screw-threaded inlet-opening at its lower end and a like outlet-opening inits side. The ordinary gas-conducting pipes are attached to the regulator at said openings,the service-pipe to said inlet, and that which supplies gas to the burners to the outlet. The upper end of the valve-ease is screw-threaded to receive the nut K,having a central opening through it, as shown, and at the lower end of said serewthread is an annular seat, 18. y

The valve-case has cast in itthe hollow cage-receiver n, of substantially rectangular form in cross-section, whose upper wall has one end united to the side of said ease, and its lower wall is united to the upturned edge of the diaphragm m, which extendsin a horizontal direction across the case 7e, just above the inlet of the latter, and between the said up turned end of said diaphragm and th adjoining inner side of the case h is thereby formed a gas-passage, z, through which gas flows from the said inlet-opening to the interior of the cage-receiver n. The upper and lower walls ofthe latter are provided with circular perforations to receive the valve-cage e,and circular (No model.)

seats 16 and 17 for the anges on the valvecage, as below described. Said valve-cage consists of a head, 13, having a flange formed around its border, which is seated on said seat 18 of the ease lz., and from it projects upwardly the tubular stein c', and attached to its under side are the downhanging legs 6 (i 6 6, having the laterally-prejecting flanges 7 and 9 surrounding them, said flanges being Seated on the upper sides of said upper and lower walls of' the cage-receiver a. Said legs 6 (shown in cross-section in Fig. 3) extend through said lower wall ofthe receiver 11, and form between their inner edges a guide for the lower end, 3, of the doubleheaded valve o, the lower seat for the latter heilig formed at 5, between said legs, and the seat for the upper end, 2,0f said valve being formed at 4, also between thelegs G. The upper end, 2, of said valve o is made of less diameter than its lower end, in order that said upper end may be passed through the opening surrounded by the valve-seat 5, to place it within the cage. The gas-passages, as indicated by the arrows in Fig. 1, are between the legs 6 at 12. A glycerine-eup, b,eontainingasuitable quantity ot'glycerine,f, is soldered or otherwise suit ably secured to the upper end ot the said tubular stem e', and that portion of the bottom ot' the cup b directly over the center of said stem is perforated to let the valvespindle d pass freely therethrough, and surrounding said central perforation are a series of other perforatious, fi, sufficient in number to form in the aggregate an unobstructed gasway for the free passage of gas through the stem einto theinverted-cup-shaped gas-holder a, and vice versa. Said gas-holder a is secured to the upper end of the spindle d by the nuts a' af, and the lower edge of the holder dips into the glyeerinef, as shown, thereby sealing the gasholder in the usual manner. The valve o is attached to the lower end of the spindle d, as shown, the latter extending from the apex of the gas-holder through a portion of the bottom of the glyeerinecup and the stem e to within the valvecage e. The bot-tom of' the glycerine-eup b is elevated above the level of the glyceriue f, in order to provide a gas-inlet therein through perforations fi, without pro ICO ' tween said flanges and seats, and the nut' K being` screwed against the head 13, all; of said beari iig-faces are brought closely together, an d gas-tight joints are formed between them. The course of the gas entering the said inlet to the caseh is as indicated by the arrows in Fig. l, and the gas enters the open end ofthe receiver n, passes between the legs .6 ofthe valve-cage, and thence up and down through the valve seat openings therein, passing between said legs, between the head 13 and {iange 7,and under the receiver n to the outlet of the case h. The gas freely passes up the stem e into the gas-holder a, and the variations of Apressure either in the supply or by reason of the consumption of more or less gas causes a. movement ot' the gas'holder up and down, and a consequent movement of the valve o toward and from its seats, thereby restricting the gaspassages between the latter and the valve 'when there is an excess of pressure, and increasing the size of said passages when the pressure is low, thereby regulating the quantity of gas which may pass through the niarhine, so that there is little, if any, variation thereof under different pressures', the burners being the saine under said varying conditions.

VVhat I claim as my invention is- 1. A gas-regulator consisting of. the following elements, viz: a valve-case, h, having the requisite inlet and outlet openings and ascrewthreaded opening in its upper side, through which the valve-cage is introduced, and having ahollow cagereceiver, n, formed therein, one end of which is open to receive gas, and whose upper and lower walls are perforated to receive the valve-cage, combined with a valve-cage, e, having side openings and valveseats therein and anges thereon to -bear on said walls of the receiver, and having the head 13, provided with the tubular stein e,the nut K, the double-headed valve o, the gasholder a, the valve-spindle d, connecting the latter and said valve, and-the glycerine-cup bp,

permanently attached to the upper end of said hollow stem, substantially as set forth.

2. The val ve-case h, having the hollowcagereceiver n therein, the valve-cage e, passing vertically through said receiver and provided with two valve-seats and the hollow stem e',

the nut K, securing said cage to the case hand d to said receiver, the double-headed valve o, the'gas-holder a,the spindle d, passing through said stem and' connected to the said holder and valve, and the glycerine-cup b, permanently attached to said hollow stem, combined and operating substantially as set forth.
