Description

`@attra Vtaire gettati @frn HUGH. n. GdR-Ais1 n,A on NEW YORK, N. Y. Letters Patent No. x72,809, dated December 31, 1867.
IMPROVEMEN'J?l Ill SUPPLY-VdLVES FR WATER-GLOSETSL TO ALL-WHOM IT MAY CONCERN:
Be it known that I, HUGH H. CRAIGIE, ofthe city and State ot" New Y'ork, have invented and made acertail new and useful Improvement in Cocksfor Water-Closets; and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specification', wherein- Figure 1 is a vertical section of said cock as open.
Figure 2 is a similar View with the valve closed.
Similar marks of reference denotethe same parts. l
Cocks for water-closets haveA heretofore been made with a chamber into which water passes, and is gradu- .ally ejected as the valve closes, sovas to make the movement of such valve gradual. These cocks have, how- Vover, either forced the water out through a pipe or opening especially provided for the same, orinto the waterway leading to-thc closet, or else have been controlled by the gradual passage of water into a chamber. Where the controlling-chamberhas communicated with the pipe that discharges the-water, the said chamber does not always fill with water when under a small head or pressure, and where the chamber is filled gradually as the cock closes, thc'valve sometimes comes down upon its seat by aseries o f sharp blows, resulting fromthe forces ofthe water andthe spring, and the vacuum in thecontrolling-chamber. p
The nature of my said invention consists in a controlling water-chamber on the supply side of the valve, so. that said chamber is lled with water unfailingly as the valve is opened,'and is emptied, or partially emptied, by a gradual leakage,'as the .valve is closed. l l a y In the drawing, a represents the inlet-orifice of the cock, b the .delivery-orifice;l these are arranged to receive the pipes as usual. c is the bodyoi` the cock, that is to be attached -to or supported vby the hopper of the water-closet or other' suitable device. isthevalve-seat, and e the valveon the stem f, that passes through the bottom of the valve-case or body c, and is to be operated by a toe ofthe rock-shaft on which the pan ofthe water-closet is swung, or by any other suitable means, so as to open the valve when the water is to be allowed to run to the closet. The lcap L'is screwed upon the body c, and confines the diaphragm valve-seat Z, packingring i?, and elastic valve 3, the'said diaphragm [having a holeor holes beneath the valve 3. The valvestemf passes through the diaphragm 71, and is formed with a piston, c, packed to move water-tightl in thecylindrical portion of the cap t, and m is' a spring to close the valve. The valverod f maybe made as a pipe, to-allow leakage to pass' into the water-closet, should the piston k at any timebecome leaky.
It will now be understood that when the cock is closcd,`as in iig. 2, the pressure 'of the water is partially balanced in its action on the valve e and piston 7c, the spring m keeping the valve closed. When the val've .is
raised,.the` piston c is also moved, and thc water ilushcs into the controlling-chamber o, through the diaphragm l, lifting the leather valve 3, and that closing by thc pressure ofthe water as conlined in o, prevents the springgl m closing the valve e until the waterhas been forced gradually out of said chamber o. I find that the leakage around the stcmf, through the'diapbragm Z, is generally sufficient to allow the' necessary time to be consumed in'the valve-closing, but' any desired character of opening for the leakage maybe provided; and'it will be evident that the valve 3 might be attached at its centre to the diaphragm Z, instead of around theedgcaby the cap 7L, and, if desired-the leather 3 may extend to and surround the spindle, and be cut to form a valve orv valves,` and a smallvhole for the leakage be provided through both the leather and the valve-se`at Z.
What I claim, and desire to' secure byLetters Patent, is- .Y Y y The water-chambero, in combination with thevalve le, when said water-chamber o is placed on 'the supply side ofthe valve, and arranged substantially as specied, so that the water is ejected from said chamber as the valve closes, for the purposes specified.
I also claim a diaphragm-valve, '3, placed between a moving piston, and the valve c, to be controlled substautially as set forth. l
In witness whereof, I have hereunto set my signature, this twenty-sixth day of September, A. D. 1867.
