Be `it known that 1,4 FEEDERrc W. WIESE- BROCK, of Brooklyn; inthe county of Kings and State of New' York, have invented certain Improvements in Gas-Regulators,lof which the" followingis a full, clear, and exact description, reference' being had to the accompanying` `drawingand the letters ofI reference marked thereon, making part of. this specification, in

1 `which `is represente a cross-'section of 'my improved regulator in position'.`

The nature of my i entionfco'nsists inarrangingin a suitable shell, provided with an inlet andV discharge opening.' or tube, a. valve, ,which isprovidedwithastem having a spring arranged :therein in such. manner-.that itstension f shall be constantly employed in` so .actmg`on" the valveas to cause the same ltfo close 'tliefventvv or orifice through .which @gas is supplied to the shell. Tlilly'invention *also consists in 'cennectingthe valve, through suitable gearing, with an 'elastic diaphragm, and to which is secured a plunger v inwerking `:through-an 'adjustable -screw-cap, and in au 4ranging `in said' plunger-a spring, aud which a fsollacts" inv4 connection with saidscrew-capv as to regulate at pleasure the supply of g"as`that sllllbeffed to'fth'e shelland this, entirely irrespective of tlieam'ouut ot' lpressure 'in the gas-containing vessel. My inventionA also `consists in providing the ual've with a' rubber 'head or. ivfsfasller,fand` which, in connection with the 'ccuieallsliaped wallwlnch surrounds `the gas-supply vent or'g'oriiice, provides a most secure means ofentirely closing said orificelleimtrutio sperati@ '0f myv in# `ti'litelrelfe as follvvfferV 'f 1 l t thesliell, and is constructed vout of any suitable mateljalgjandj'may be of 'any desired formand dimensions The shell.

"T e bottom or end piece B1 is screwed onto terial. This-washer`e,in connectionu with thcone shapeof the. nozzle D,p'rovides-a'1nost reliable means, when' desired, of so closing the orifice d as to entirely, and in thefmost eectual manner, shut o r cut o all communi; cation between the gas-containing vessel andthe interior chamber of the shelle4 Ezis acoil' or ,other spring, soarranged, in 'co'nnection with the valve E and its stem El, that its tension shall `be constant-ly exerted todrive the .washer e 'against the nozzler, as itwere, l valve-seat D, and thus `close t e'vent or ori-l ice d. Il lre top or upperend piece Bis of the form.. shown yin the drawing, and Vis 'provided with yar'radjustablescrew-cap, F.: When this enjpieceis screwed on, it serves to secure the elastic diaphragm G, which has its bearing on an `ammlar shoulder, af, o n the interior surface of the shell A. `'.lo'this diaphragn G, and ywhich inay be constructed ,of rubber or anyother material possessing 'the` requisite elasticitysfsecured theplungerH,by means of the 1,. screw thread h on' the stem or rod El., Thus :it will beseen the diaphragm G has a d l'able flinc'tion-rst, it serves as a w'asher' to form 'tightjoint' between the shell A and its upperend piece B, and tlienofallowing suiicient play tofthe plunger H, to open and close the valve. f

Thisrod or ,stern l* of the plunger H-'is provid- )..ed with a coil-spring, B, one end of whichvha's.'

its bear-in g on the upper surface of the plunger H, while its opposite end4 has its bearing on the under surface of the adjustable screw-cap F. The plunger rod or stem has, its bearing in an opening, f, at the center of the screw-cap F. The plunger' H is. connectedl with the valve Eby means of a yoke or other suitable gearing, W. To prevent the overstraining of the flexible diaphragm 'G a conrex4 metallic diaphragm, G1, may be vplaced on th'e'upper surface of )the same, its Aupward curved form allowing free movement or play Ato,.thediapl'lragm G. rlhis metallic'diaphragm Gl has a suitable opening through which freely passesandfzworks the plunger and its` rod. This." diaphragm also acts, as it were, as a :braeeft prevent the elastic diaphragm from bein'gtwisfed by the screwing on of the endpiece B1.; The uppersection, B, may be provided with a check-arm -or 1ever, 'B, -so constructed and arranged as to prevent the cap F from :beingentirelyunscrewed or detached from theend piece B1.

Having` now given a full a-nd detailed description of my improved carbonic-gas regu@ l-ator, I will proceed to describe'its mode of operation. y n

Carbonio-acid gas being supplied to a suitable vessel, X, at a high pressure, so as to carry the largest quantity in ythe smallest v olnlnethe apparatus is attached vto this vessel X, as shown at K and K', or by any otherv convenient means. The pipe()v1 is then-,"by hose L, or otherwise, attached 'fto the keg `Y containing the lager-beer or other liquid which itis designed to charge. The screw-cap'F, being screwed up so as to leave the' spring 'Hv2 freei'rom any 'pressure which would have the' effect.` to levclopits tension, even if the gas is turned-on, it will not pass tothe interior chamber oi.' the shell A., as the tension of 'the 'spring E. will so act on the valve El as to ciectuully close the orifice d, A So so'nasthe4 Iezlz't'ger begins to be-drawn ott' thefcapis4 'L serew'ed down, compressing inA itsdownwdrd' movement the spring H2, and Wliichrover coming the tension of -the spring E,.Jwill de press thediaphragm Gr,'and which, carrying with it the' plunger H, will, through the gearing YV, canse thel valve E to fall,-and which vleaves theorifce d free for the egress of gas, and; which,`rushing therethrough, soon iills the chamber until its density, acting on the .plunger il, aided by the tension ofthelspring E2, will overcome the pressure of the spring guideas described.,

H2, and thus close the valve. This plunger 'H or the dimension of the same is according to the character or nature of' the purpose for which the regulator is designed to be used.,

'sity or pressure of, thelsame again closes the valve, as before, and thus the valve is' automatically opened. and closed as occasion requires. When the screw-cap F is screwed down -to such a position that the pressure on the liquid-is suieient to draw olf the same with the desired spark1ing,.it is left in that position, and the apparatus will continue to discharge just this desired amount of gas au'- tomatically. By' the screwing down. of said y screw-cap F the pressure 4of gas can be ad- 4 justed 'at will. The screw-cap 'is so arranged that, if it is screwed downto the lowest point, onlya perfectly safe quantityof gas can pass through the apparatus.

By the use of my apparatus I can, use a gaseous or liquid medium at any desired pressure, and. entirely irrespective of the pressure of the gas infv lthe 'gas-containing' vessel, of` either sideof. the valve, a result; obtained by @none-of the present regulating apparatus.

The .simplicity of the Aapparatus also, 'is a uard against it becoming easily out of order. s)What I claim as new, and desire to secure byLetters Patent o f theUnited States, is- 1. In connection with a suitable shell, the

pipe O and coneshaped -nozzle D, thel chan# nels c1 d, each of which being connected as shown, in combination with the valve E, washer 4@stem El, and spring E.

A 2.y The plunger H, having a rodA Hl, spring H, screw-cap.-F,.diaphragm G, and valve E,

thelatter' being connected to the plunger by l any suitable gearing,- jthe whole being combined and arranged to operate substantially Intestiiony whereof I have signed my name to-this specitication'in the presence of two subscribing witnesses.y
