SPECIFICATION forming part of Letters Patent No. 266,484, dated October 24, 1882.

Application filed June 2, 1882.

To all whom @t may concern:

Be it known that I, TOLBERT LANSTON, a citizen ot' the United States, and a resident ot' NV-ashington, in the District ot' Columbia, have invented anew and valuable Improvement in Faucets; and I do hereby declare that the followingI is a t'ull, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part oi'l this specification, and to the letters and tigures ofreference marked thereon.

Figure l ot' the drawings is a representation ofthis invention inalongitudinal section. Fig.

2 is a detail cross-section.

The object of this invention is to provide a t'aucetwhich cannot beleftin condition to waste; and it consists, first, in providing a faucet with an automatic cut-oft' or stop beyond the control ofthe operator; secondly, in the construction and novel arrangement, in connection with a water-chamber diaphragm and reciprocating' valve, of an outlet-passage leading from said chamber and an inlet-passage leading thereto from the seat ot' the turning or hand valve; thirdly, in the combination, with an automatically-operatedstop-valveinthemaiuwater-way ot' the faucet, ofthe independent hand or turning valve; tourthly, in the combination, with the diaphragm-chainber and the reciprocating stop-valve, ofthe main water-passage from the scat ofthe operating-valve through the seat ot' the stop-valve and the secondary water-passagesleading to and trom thediaphragm-chamher,and independentot'thewater-way through the stop valve seat; ifthly, in the relative arrangement ot' the main water-passage and the secondary water-passage with reference to the water-way through the turning valve; sixthly, in the accelerating drip-slide in the outlet-passage from the diaphragni-chamber; and, finally, in the general combination, all as hereinafter set forth.

In the accom panying drawings, the letter A ldesignates the body otl the faucet, and B a closed chamber arranged at the upper part of the same. Below the chamber B is made iu the faucet a valve-chamber, O, usually located in the turning valve or plug F, which is arranged in the seatm. In thelower portion ot' the chamber C is formed a valve-seat, a., surrounding the opening b, which leads from the valveehamber into the spout or discharging end D ofthe faucet. The valve-chamber is provided with a top, c, having a packed bearing, d, for

(No model.)

the stem e ofthe stop-valve E, which is ground or covered with rubber to tit the valve-seat a. In the upper part of' the turning valve F is located a partitioned box, C, or double way, which is usually threaded exterior-ly to engage an interior thread ot' the plug F, and is thereby made adjustable. The partition o separates the box C into two water-ways, b and c', whereot'the former, being' the inletway,is provided with the inlet-opening d in its side, and thelatter, being the outlet-passage, is provided withtheoutletopeningoropeningse. Through the topcare made theopeuings g and h', whereby the ways b' and c' communicate with the upper closed chamber, B.

Grepresents the inletend ofthet`aucet,whose passage communicates with the turning` valve, and is made ot' sufficient size through the seatm ot' said valve to accommodate the opening d ofthe way b, and the main opening d ofthe turning valve,which is arranged below but not in line with said opening d.

Transversely arranged in the chamber B is a diaphragm, II, of tlexible material, having a center connection, fw, whereby it is attached to the stem c otl the stop-valve. ln the upper part ot' the chamber a guideway, ai, is provided i'or the stem c, and around said stem a spring, K, may be arranged, its tension serving to assist in pressing the stop-valve downward to its scat; or the upper portion of the chamber may be made air-tight, andthe stopvalve, being seated under slight pressure, may be Operated by the compression of the air or by the combined action ot' the air andan nuxiliary spring.

In the wall of the faucet is formed apassage, p, which is provided with an inlet-opening, j', near its upper end and an outlet, L', at its lower end, which communicates with the spout end D of thefaucet. The inlet j" ot' this passage is arranged to register with the outlet opening or openings e ot the water-way c when the hand-valve F is suiticienlly turned for this purpose. \Vhen this plug or halidvalve F is operated to 1ct the water flow communication will be first established through the opening g and the way b with the chamber B, and the water will tlow intosaid chamber, raising the diaphragn'i II and the stopvalve E, the stem ot' which is attached thereto. The valve F being further turned, the opening d will be closed, and the main waterway through the valve will be opened, admit- IOO IOS

tin g the water into the chamber C, whence :it passes out of the faucet through the valveopening b and the spout D. In order to out the water-flow off, the plug F should be turned sufficiently to bring one ot' its stop-walls t in position to close the main opening through the valve end m. Should this, however, not bedone, and the water-way be lett partially or Wholly open, the flow will be stopped automatically after a limited time by means now to be described.

To the valve-stem e is connected a checkrod, R, which extends through the openingh of the outlet-way c. This check-rod is parallel to the valve-stem and reciprocates therewith. The check rod or slide R moves through the opening h', which is of but little larger diameter than the rod, being so constructed in lorder that the water from the chamber B shall pass through it in a slow and gradual manner.

- The upper portion or neck n ot the check-rod is of smaller diameter, and is designed to allow the water to pass more freely as the valve E approaches its seat. The accelerated movement of the water is also designed to facilitate clearing the check-rod of any sediment that may have gathered around it. The diameter of the check-rod with relation to the opening h', through which it moves, and the plug of the diaphragm H should be arranged to provide for a ow ofwater of the duration which will be required for ordinary purposes. At the end of this time the iow is stopped bythe engagement of the stop-valve E, with its seat a, whether the operating-valve be turned to cut off the flow or not.

Below the valve E in the spout D a guard, J, may be arranged to prevent access being had to the valve from the'mouth of the spout; or the spout may have a bend below the valve for the same purpose.

Sometimes it maybe desirable to arrange the stop-valve so that it shall be independent of the turning valve and at a short distance therefrom. Then the chamber ot' ,the stop- Valve and the water-passages leading to and from the chamber B can be formed in the wall of the faucet and the size of the turning plug can be very much reduced. The construction of these faucets can be otherwise varied by those skilled in the manufacture of such articles.

In the construction illustrated it will be observed that the inlet-opening d of the partitioned box C and the outlet-openings e thereof are soarranged that no two ot' them can come into action at the same time, and one of the outlets c is arranged to act concurrently with the opening d ofthe main waterway through the plug, so as to relieve the diaphragm at once when the water is fully turned on. When the plug F by means of the operatinghandle has been turned sufficiently to allow a llow from the inlet tothe discharge opening of the faucet the opening d will be moved around leeway from the inlet G, and the upward passage of water to the chamber B will be prevented. As the passage b is closed, no morewater can rise to the said chamber until the operating-handle is again turned 5 but the water within this chamber, as before described,

will pass slowly out ofl the opening h through the passage o', which in a limited timewill allow the valve to vdrop to its seat and close the discharge-openin g.

From the foregoing description it will be readily seen that when the liquid enters at the inlet G, it must necessarily first rise to the chamber B in sufficient quantity against the diaphragm therein to raise the same, which will simultaneously raise the valve E and open the way from the said inlet to the discharge D, andl as the rod It is attached to the valvestem its neck will be raised above the opening h and'will partly close the same. When the faucet is open in full, or nearly so, the opening D of the plug F will register. with the inlet G; but should the faucet be left open or partly closed, through negligence or otherwise, by the operator the chamber B will, by the dripping through the opening h for a reasonable time, become entirely empty and allow the stop-valve to drop to its seat and close the discharge-way.

Having described thisinvention,whatlclaiin and desire to secure by Letters Patent, is

l. A faucet having, in connection with a water-chamber, a diaphragm therein, and a check-valve connected to said diaphragm, an outlet-passage leading from said chamber and an inlet-passage leading thereto from the seat of the turning or hand valve, substantially as specified. e

2. A faucet having a main water passage or outlet and a secondary independent waterpassage, combined with the diaphragm-chamber and the stopvalve, the secondary waterpassage connecting said diaphragm-chamber with the main water-way beyond the seat of the stop-valve, substantially as set forth.

3 In a faucet, the combination, with the chamber B, diaphragm H, and reciprocating stop-valve E, of the hand-valve F, valve-chamber C, water-passages, and the slide-check R, substantially as specified.

4. A faucet having independent of the main water-way a secondary water-way through a diaphragm chamber, and an accelerating dripcheek rod in the outlet from said chamber 'connected to the stem. of a stop-valve which is attached to the diaphragm in said diaphragmchamber, substantially as specited.

5. A faucet having a positive automatic cutoff or stop for the llow arranged in the'main water-way, and inclosed so as to he beyond the control ot' the operator, substantially as specitied.

In testimony that I claim the above I have vhereunto subscribed my name in the presence of two witnesses.
