Be it known that I, Isaac JUDSoN, of the city'and countyof New Haven, in the State of` Connecticut, have linvented a new and useful Improvement in Hydraulic Regulators; and I do hereby declare that 'the'following is a Full, clear, and exact description of the construction, character, and operation'of the same, reference being hnd-to the accompanying drawings, which make .part of this specil'icatiomin which- Figure 1 is a section cut through the centre in thedirection of the induction and eduction pipes, showing the relative positions of the valves, diaphragme, rings, Ste. i 'i n Figure l is a' perspective view of one of theV flat rings or annular disks used for varying the-relative pressure. t My' improvement consists in constructing the regulator with one valve, to the stem or wnlchI attach two elastic diaphragms, of different extent of hearing surface, so that the water,which `enters the smaller apartment through the induction pipe, muyiirst act upon the smaller diaphragm, the eiect of whichwill be to open the valve and allow the water to pass into the other apartment, so as to press upon the other or larger diaphragm, the tendency of which will be to close the valve, and therefore to regulate the pressure at the eductionfpipe by `the-.pressure at the induction pipemodified hy' the dierenceof the surfaces of the two diaphragme, whichmay `he carried to any desired extent bythe useof flat rings or annular disks. i i I I p I 'makethe main frame of cast iron, or any other suitahlematerial, substantially in the form or shape indicated in section 'at A A','g. 1, with an. induetiou pipe or passage, as indicated at B, and an eduction pipe or passage, as indicated at O, 'and a proper seat for the valve, as indicated at g gs -On one side of thisframe I fit a cast-iron-convex side or shell., as indicated at D, which forms a. vacant chamber, as indicated-at E. And 4on the 'opposite side I it a similar cast-ir n convex shell, but considerably smaller,'asindiceted at F, forming a vacant chamber, as indicated at G. These two semishells, D and F, are to be secured to the main frame A A, by a suitable number of screws passing through 'their flanges, as at a a and b which scr'cws also pass-through vthe outer portion, ncarthe peripheryA ot1 the two diaphragms, to secure their outer edges inl a firm condition. I And in these shells I make spaces in which rings or annular disks ma)rrest when desired, as indicated at li and z' iig. 1. I make the valve-stem lof cast iron, or any othersuitahle material, substantially oi'` the form or shape indicated in section at H` K L, g. 1, with a suitable annular groove or recess,as indicated insectionat c c, into which I t a leather or any other suitable packing for the valve. And at suitable distanceseach way` from this valve I make projecting shoulders on which the diaphragms are to rest, as indicated at K and L, and onthe extreme ends I cut screw-threads to receive bindingn`uts, over suitable washers, to hold thel central part of the diaphragms in their` places iu all their relations to `the other parts of the apparatus. .Ivmalre the diaphragme M and N of prcpared India rubber, or any other-suitable material, of the proper sizes and'thicknesses to operate as indicated. i v i y t Having made the several parts as before described, I slipthe'smaller diaphragm 'Non t'dtlievalve-stsm at L, put on the washer, and turn onfthe nut, asindicatedat I 'then pass the valve-stem through the smallest snide opening in the frame, till the packing c c in the valve H-rests on theV valve-seat g y, and put on the shell F,4 -securing `it by suitable screws, which I pass through the ange atb b, 8vo., end'thediaphregm N, so as to render the apartment G water-tight. I then put on `the large diaphragm M,'with its washer and nut, as indicated at d, put on the shell D, and secure it with screws which pass through the tlange at a a, itc., and diaphragm M, 'so as to close or render the apartment E water-tight.. t n

To use this apparatus I connect the induction pipe Bwith' the supply pipe, and the eduetion -ppe C with a faucet (or other Aproper means) for using ,the water. I. then let in the water, whch,ihy pressing on the inner side of the smaller diaphragm N, will foreethediaphragm into 'che vacant chamber or apartment Gf, so' a's tcraise the valve from its seat and allow the water to passinto the larger apartment, as indicated bytlxeidart, when it will press upon the larger' diaphragm M, which will tend to force the diaphragm into the vacant chamber E, and to close the valve, wheu'the conjpound etect, as to forcerof the water passing in at B `and out at C, wlli be invcrselyas the extent of yielding surface of the diaphragm fs" is t`o that or' M,`so that if :L1-ing` or annular disk, liketigr 2, should b placed in the larger shell, as indicated at It h, fig. I; thefd'itl'erence oi theyielding surfaces would be made less; but if placed in the smaller shell, as indicated 'at e'4 z', the diii'ereuc'eof the yielding surfaces would be made greater; so that by the original proportions of the diaphragms, and by the use oi mular. of dierentwidths, the -ierence between the force at the induction and edntion pipes may 'he @de to vary toany xiesiredextent. Andforthe onvenionce of emptying the-regulator, (when the water is fut oi hack of it,) n. screw,"as".P, `tapped info the shell' '1), maybe turned in, so as to open the volve,'and `to l'd.itopenatnytme,if desired. "l 4 i What I claim as my nventionland desire tojseoure byLetters Patent, is- 1. The combination ofthe'tro dnyhmginsv with the va'lve and its stem, when they arev constructed, arranged, ad ittefor use, euhtantiiy-as vherein described nud-'set fox-ith.

2 I o1aim the ombnato oa yring or' anuu'lar disk with eitherlof the diaphragme, when .sed 'to les'sen le extent of the' yieldng'eurfaoeof ,the xiiaphragm, substantially as herein described nd set forth.
