GAS-REGULATOR,

SPECFCATION forming part of Letters Patent No. 344,990, dated July 6, 1886.

Application tiled February 13, lBSf. Serial No. 191,834. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM C. RossNEY, of Hyde Park, in the county of Norfolk, State of Massachusetts, have invented a certain new 5 and useful Improvement in Gas-Regulators, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention Yappertains to make and use Io the same, reference being had tothe accompanying drawings, forming part of this specilication, in which- Figure lis a vertical section of my improved gas-regulator, some of the parts being shown I5 in elevation; Fig. 2, a side elevation o f the cupvalve detached; Fig. 3, a horizontal section of the cup-valve taken through the center of its body; Fig. 4., a top plan view of the hub or valve-seat, and Fig. 5 a side elevation, show- ;,O ing a modification of the cup-valve.

Like letters ofreference indicate corresponding parts in the different figures of the drawings.

My invention relates to that class of gasregulators which are operated automatically by the pressure of the gas; and it consists in a novel construction and combination of parts, as hereinafter more fully set forth and claimed, by which a more effective device of this character is produced than is now in ordinary use.'

It is well known that in nearly all gas-regu;

laters having valves which are opened and closed bythe pressure of the gas in such a manner as to automatically control the supply delivered to the burners rnuch difficulty is experienced from the valves becoming clogged or stuck by gas-tar, or by the carbonaceous deposits from the gas, while others are so constructed as to be less sensitive and eertain in their operations than is necessary to produce the best results.

My invention is designed to obviate these and other objections, which are hereinafter pointed out; and to that end I make use of 4 5 means which will be readily understood by all conversant with such matters from the following explanation: l

In the drawings, A represents the body, B

the gas-holder, C the cylinder, and D the base, 5o ,ofthe regulator, these parts being preferably composed of cast-iron. The body A is cylindrical in form, but may be made in any other suitable shape, and should be about six inches in diameter and eight in height in a regulator for use with an induction-pipe one inch in diameter. A cover, P, is secured to the top of the body A by the screws -235 but instead of being secured in this manner it may be provided with an annular downwardly-projeet ing flange for keeping itin position; or it may 6o be secured in any other suitable manner, the cover being also preferably composed of castiron. Projecting horizontally and inwardly from the walls of the body A there is an an-l a nnlar flange, z, on which is erected a cylinder, C, concentric with said body and open at either end, the body A, flange z, and cylinder C being cast integral, orin one piece; but when not so formed they are connected by gas -tight `joints. rlhe bae D is also cast integral with 7o the body A,` of which it forms a part; but it may be made separately, if preferred, and be united to the body proper by screws or other suitable means, whcrebya gas-tight joint is produced andthe parts held in proper posi- 75, tion. Within the body A, and preferably disposed on the base D, there is 'a vertically-arranged cylindrical hub or projection, G, which may be cast integral with said base; but when not so cast it is united thereto Eo tor to the induction-pipe E in such a manner as to form a gas-tight joint therewith. An annular reservoir or chamber, x, open at its top, is formed in said hub, which hub is also provided with a vertical opening or pas 8 5 sage, H, extending centrally through it from top to bottoni. A downwardly-closing cupvalve, I, has its lower portion disposed in the chamber x, said valve being provided with a stem, 22, which is adjustably jointed or con- 9o nected by the pin K to a Inain counterbalvancing-lever, M. This lever is furnished with amoving` counter-balance or weight, N, and

the weight provided with a screw, 40, for securing it in any desired position on said lever. Projecting inwardly and horizontally from the walll of the body A, above the hub G, there is a-bar or fulcrum, L, having at its inner end a downwardly-projecting arm, 24, f; provided with a series of holes, i. The outer 10o end of said bar is screw-threaded and passes through a hole inthe wall of the body A, being properly packed and secured in position by the

locknuts

25 and 26, by which nuts and screw-thread the bar is also rendered adjustable laterally of said body. The lever M is provided at one ofV its ends withv a series ot" f. Au auxiliary lever', Q, having its outer end jointed by the pin w to the wall of the body A, or lo aprojeetion thereon, isarranged horizontally within said body opposite the bar L, and preferably on the same plane therewith, said lever being both laterally and vertically adjustable. The lever Q is provided with a series of holes, k, and is connected with the lever M by a short verticallyarranged rigid bar or link, S, said bar being detachabl y and adjustably pivoted or jointed at its lower end to the lever M by the pin 27, and connected in like manner to the lever Q by the pin 28. A vertically-arranged rod, J, having its lower end adjustably jointed or pivoted to the inner end of the rod Q by the pin 29, is firmly connected by means of the lock-nuts 1/ with the gas-holder B, at or near its center, said rod being preferably secured iu the top of the holder in such a manner as to be readily adjusted vertically therein,- and yet so packed as to form a gas-tight joint therewith. Therod is elongated at its upper end and passes loosely through the cover P, as shown at 30, thus permitting the air to enter the-chamber above the holder B, and the long arm of the lever M to be depressed by pushing said rod down,

` and the valve I opened to permit a free dow of gas through the regulator, if at any time the same should be required, and vice versa. The induction-pi pe E opens upwardl y through the base D, beneath the hub G, into the passage H, the joint between said pipe aud base, and also between said pipe andthe hub, being gas-tight. vAn eduction pipe, F, opening outwardly through the body A, is disposed below the flange z, the joint between said pipe and the body being also gas-tight. rlhe latter pipe may, howe'venlead outwardly through the base D, if preferred, instead of through the body, as shown. An annular chamber, m, isformed between the cylinder C and walls of the body A, the top of said chamber being open.

.A quantity of some suitable liquid, r, preferably quicksilver or mercury, is placed in the chamber 'm for packing the holder B, the lower edge of said holder being immersed in said liquid when the helder is in use. The chamber'x in the hub Gflares, or is dishshaped, its outer walls being inclined at an angle, preferably of about forty-five degrees, thereby l making said chamber wider at the top than it is at the bottom, as shown in Fig. 1.

Its outer walls are also grooved or corrugated, as show n at y inlFg. 4. The body ofthe cup valve I is vertically grooved or corrugated, as shown at :v

' seat for the valve I, the lower ends of the teeth '17 being immersed in the liquid when the gas is passing through the regulator. When the regulator is used in a position where it is not perfectly stationary, or when it is disturbed by the jarring of the building in which it is placed-as, for'instauee, in a factory where heavy machinery is runniug--the liquidt is liable to be slightly disturbed, or caused to ilow from one side to the other of the chamber thereby causing the gas to be delivered intermittently to the burners, or the lights to dicken To prevent the liquid t from circulating in the chamber .fr when the regulator is jarred or disturbed, as described, the corrugations y in the outer walls of said chamber and the corrugations 16 in the body of the cupvalve I areemployed, the liquid falling into the grooves or corrugat ions and thereby being prevented from flowing or circulating as freely as it would were the outer walls of the chamber and body of the valve plain or smooth. I do not, however, confine myself to using the corrugations y, as instead of the corrugations one or more projections of any suitable form may be disposed on either wall of the chamber and extending from top to bottom thereof, for accom plishiug the same result. The inner wall of the chamber may also be corrugated, instead of the outer, if preferred, or both may bel corrugated. Neither' do I confine myself to eorrugating the body ofthe cup-valve I, as instead of the corrugations one or more projections of any suitable form may be disposed on the outer or inner side of the valve, and extending from top to betteln thereof, for performing the same function. A fulcrum bar or standard for supporting the lever M may be erected on the base D, it desired, and used in place of the bar L. The liquidt and the hub G, provided with a chamber for said liquid, constitute a liquid valve-seat for the valve I.- rlhe pin w serves as a fulcrum for the lever Q, but any other suitable fulcrum may be employed. 'lhe gas-tar and other carbouaeeous deposits from the gas, which tend to collect on the lower edge or teeth, ,157, of the valve I, will be washed or detached from said valve by the liquid or quicksilver t as the valve rises and falls, and be blown by the inflowing gas against the outer walls of the chamber w, to which they will adhere, and

,thus be prevented from interfering with the proper working of the valve. It is somewhat important, therefore, that there should be sufficient space between the valve and the outer walls of the chamber x, at the surface of the liquid 't, in order to prevent the tar and deposits, when once detached from the IOS valve, from returning and readliering to it, and hence the outer walls of the chamber x are iiared or inclined, as shown and described, whereby the requisite space is afforded around the v alve I at the surface of the liquid 'and the use of the liquid economized, a'less quantity being required than would be necessary if the chamber were of uniform width throughout. The jarring or disturbance of the regulator when in use, as described, is also liable to causethe cup-valve I to oscillate or swing slightly on the pin K, and thereby disturb the even flow of the gas orcause the lights to tlicker. To obviatc this difficulty the parts are so constructed and arranged that the eX- treme lower portion of the valve is kept immersed beneath the surface of the liquid twhen the regulator is in use, and an opening` or openings for the passage ot' the gas through the valve is formed therein above the level of said liquid, thereby preventing the valve from swinging or oscillating when the regulator is jarred or disturbed, said opening or openings being adapted to be closed bythe liquid when the valve is sufficient] y depressed.

y In the valve shown in Figs. l and 2 the spaces betvcen the teeth 17 constitute the openings for the passage of the gas through the valve, the points of said teeth being immersed in the quicksilver or liquid t, to prevent the valve from swinging or oscillating; butinstead of serratingthe valve or constructing it with teeth it may, if preferred, be made with slotsl or openings l19 l'or the passage of .the gas, as shown in Fig. 5, its lower edge being immersed in the liquid t in substantially the same manner as when the teeth are employed. One or more of the slots 19 may be used, as required, and they may also be elongated Ato open downwardly through the lower edge of the valve, it'dcsircd. 'I do not, however, contine myselt' to scrrating the lower edge ofthe valve or to providing it with openings for the passage of the gas, thegas passing beneath the i extreme lower edge of the valve in entering the regulator when the openings are omitted. Neither do I confine myself, when it is serrated, to serrating the entire lower edge ofthe valve, as one or more A-shaped openings may be formed therein, although Ideem it preferable that its lower edge should be entirely serrated. Neither do I confine myself to making the spaces between the teeth strictly A-shaped, as this form may be varied without departing entirely from the spirit ot' my invention, nor to making the teeth 17 V-shaped or pointed, as the form ot' the teeth may also be varied, if desired. I however deem a cup-valve which is serrated or provided in its lower lportion with one or more A-shaped openings for the passage of the gas, the smaller part or apex being uppermost, as shown in Figs. l and 2, superior to one which is provided with, one

Y or more openings having parallel or approxifrom its base to its apex, and hence the valve requires to be but slightly depressed to greatly reduce `the volume of the intlowing` gas, and vice versa; or, in other words, the ilow of the gas through a A-shaped opening in the valve, when the opening is arranged as described, will be in inverse ratio to the rise or fall of the valve, as the case may be, whereas when the opening is of uniform width` the quantity of gas passing through it will correspond with thedistance the valve rises or falls. Y

The auxiliary lever Q and connecting bar or link S maybe dispensed with'and the rod J jointed directly to the lever M, if desired. I

however deem it preferable to use them, as they enable the valve to bemore delicately adjusted than is possible when the rod J is connected directly to the lever M, and also prevent the lower end of said rod from being sprung or moved laterally to such an extent as it is liable to be moved when thelever lQ is not employed. Alt will be obvious that by moving the bar S toward the fulcrum w of the lever Q the distance which the valve I will lbe Y raised or lowered by the gas-holder B will be decreased, and that by moving it in the opposite direction, or toward the rod J, it will be increased. The weight or counter-balance N may be placed between the bar S and arm 24, if desired, or it may be placed on the auxiliary lever Q, instead of the lever M, ifpreferred. The weight may also be omitted. The top d of the valve I is thickened to give it weight, and thus enable the valve to counterbalanee to a certain extent the movable parts on the opposite side of the fulcrum-pin b.

In theA use of my improvement the gas is let into the regulator through the pipe E, passing thence upwardly through the opening H into the valve l, thence downwardly through the opening or openings in the lower part of the valve, or beneath the-valve, as the case may be, into the chamber ,90, thence into the body A and gas-holder B, and thence through the pipe F to the burners. When the gas is passing through the regulator. as described, it the pressureisincreased-fas, for instance, by shutting off aportion `of the burners-the gas- IOO IIO

holder B will be raised accordingly, y thereby drawing up the rod J, elevating the long arms of the levers Q M, depressingthe valve I, and decreasing the volume of gas delivered to the pipe F or to the burnersin a manner which will be readily obvious without a more eX- plicit description. Of course when the pressure within the regulator is decreased-as,..for instance, by lighting up an additional number of burners-the gas-holderB will fall, the long arms of the levers Q M be depressed, thevalve I raised, and the volume of gas passing through the regulator increased. v i

Itwill be obvious that the valvel, being provided with aliquid seat, cannot be clogged with gas-tar to such an extent as to preventit should it adhere to the teeth 17, or lower edge of the valve, and thereby partially close up the opening or openings through which the gas passes, it would merely decrease the pressure within the gas-holderB and cause said holder to fall and open the valve accordingly.
