Speccaton of Letters Patent.

Application lcd April 15, 1902. Serial No. 368,361.

To all whom it may concern:

Be it known that I, GnAnLns M. ECKLAND, a citizen of the United States, residing at Oakland, in the county ot Alameda and State of California, have invented certain new and useful Improvements in Valve Mechanism for CloseteBowls, of which the following is a specification.

The resent invention relates to certain new and) useful mechanism for actuating and controlling the movement oi the valve for automatically governing the sup ly of water for the flushing of closet bowls; t 1e object of the invention being to dispense with the overhead tankor the tank reservoir ordinarily employed for maintaining a body of water for rlushingr purposes, and to so arrange Jtor the valve movement that while an ample uantity'of water is .sup lied for the proper ushing ofthe closet bow and partly refilling the same with an after-Wash, the seating or' the valve shall be such as to gradually cut-oil' the flow of water from the main supply and to finally seat itself to entirely close or cut-oil the water sup ly en-tirely without noise or jar luis providing tor anabsolutely noiseless .flushing of the closet bowl, and removing the objectionable feature of the flushing means at present employed in connection with the closet equi ment or connections installed in hotels and euses generally.

To comprehend the intention reference the accompanying sheet of drawings, wherein Figure 1 is a vertical sectional riew taken through the piston-taire, said view illustrating the parts in position to entirely close the iloW of Water to the bowl of the closet; Fig. 2 is a similar view illustrating the piston-:nl `e and its controlling val :e in full upward position to open the outlet ports for the llow of water to the closet bowl, and Fig. 3 is a broken plan view of the blank from which is formed the inner c linder for the outer casing, said view disc osing the inlet ports for the flow ot water from the main supply to the outlet ports.

ln the drawings the numeral 1 is used to designate the mam supply for the water, and Within this said outer casing is itted the cylinder '8,

hazing in its top portion a Water inlet il,

l In the present case the outer cylinder is illustrated as sectional, the upper section being screwed onto the lower section, the purpose ot so constructing the said outer casing being to 'enable the interior mechanism to be readily inserted within the casing, vand to be quickly removed therefrom.

Within the pressure chamber 4 of the cylinder 3 is iitted the vertically movable piston-'ral .'e 5, said pistonffalfe resting in its closed position on the val .-e seat 6 to close the main outlet port 6 of the casing, which port communicates with the outlet 7 leading to the. connection rith the closet-bowl In the piston-zal .'e 5 is located and Works val .e controls the outlet '9 the Tal je S, which leading from the said piston-valira 5. The `al :e 8 .during its upward mcxernentv engages the under tace of the ported piston-:alie `,5 and lifts the same from its seat G, the said val fe 8 being raised from its scat and forced upward within the piston-val e 5 by means ot a handle. This handle is fitted 'within a socket in the shat't 8 lower portion of the outer casing 2, and the same is connected to the value stern 9 by means of .the leer 10. The valve stem 9 works through the slee'fe 92, .downwardly projecting from the piston' alz'e 5. The `al e 8, which has an upwardly opening cup sha ed chamber at its upper end, is normally hel Vto its seat- 12 by means of a spring 11 lsupported in the cup-shaped chamber and ha 'ing its upper end bearing against the top of the 'listen '.'al e 5.

ln t ic lower portion of the cylinder 8 are prexided the bcv eled or inclined inlet ports 10", 102, 1.03, which are formed respecti: ely with the downwardly extended slots 13, 14, 15, the slot 15 being prolonged sliffhtly beyond the depth olE the slot 14, whici slot 14 in turn extends .slightly below the depth of the slot 13. These slotted extensions ot the said inlet ports are for the purpose of permitting an inflow of a small quantity lof water to the closetbowl after the ports 10', 102, and 103 have been closed by the vertically mofrable piston-valve 5 during its downward Increment, said. inflow of water through the slotted extensions 13, .14, and 1 5 constituting an after-wash vfor the closet` bowl.

In the top justable screw 16, which screw working within theI controls'tlie eres of the port 4 in' order to regen late the time ci liush or movement ci the piston-zel .'e 5.

'On the lower portion oi the cylinder .3 tted e ring 17, hsxing openings 1?' therein. which correspond with end register with the before mentioned inlet ports i0', 102, los formed in the seid cylinder. This ring is .tor

tl; purpose of gozer-nin the eres. 'of the seid ment for the admission of the quantity ofL Water during the Flushingn action of the nel' e mechanism, the seme is locked in position by the tightening ring 18, which is threaded on the lower extremity of the cylinder 3 end., `which when seren ed up forces the upper edge of the regulating ring against the shoulder 19 of the cylinder 3 to secure the seid ring 17 in its adjusted position..

The Water enters the easing 2 through the mein supply pipe or entrsnce ier the unter, passing between the inner well ot the seid casing 2 and the outer Well of the cylinder 3 arranged Within the upper portion or section of the outer casing, and lou's into the pressure chenioer 4 of the cylinder 3 to iill the seme through the inlet 4, the pressure oi the water thus admitted into the seid pressure chamber 4 acting on the piston-' e 5 to holdthe seme down upon its sent 6 to close. the mein outlet port 6. IWhen the piston' 'ei' 'e stands in this position the ilo-w of Water to the closet-boul is cnt ed", Fis. l of the drawings. its the handle is miseri, it actuetes the le er l0 and the :el Ve stem 9 to lift the nl e 8 from ofi itssest l2 eo es to uncoj 'erthe outlet port 9, causing the ester to discharge from Within the pressure chemoerof the ycylinder 3, end permitting the pistom'fsl e 5; through the ino' 'ement of the 'fel 'e 8, to be carried to the top of the seid pressure chem'ber 4 of the cylinder. This mo' ement ofthe said piston-fel 'e iin-- co 'ers the outlet port 6', end gredueliy opens the mein inlet ports 10, 102, 1G, Athe opening ol.' which ports permits the vrs/ter entering throuffh the mein suppiy l to flow .directly into the lower portion et' the pres sure chamber LElend to escape through the unco 'ered mein outlet port into the outlet 7 leading throu h its connections to the closetn bowl for ilumine purposes. The niornent the handle is re essed, the pressure of the spring 11 acting on the/xsi 'e 8, forces the seid nel 'e to its'sest l2 to close the port 3 end pre4 'ent the escape ci wetter trom within the pressure chamber l of the cylinder 3,

ses,

permitting the Water entering' seid chamber through the inlet l to eceiiinulete therein and the pressure thereof to ect upon the piston-,elfe 5- to torce the seine down- Werd to gradually close the 'ports l0", 102, 103, end out off the mein flow of Water t0 the elosetoowlu After the mein flow oi the water lies been out oil, s smell quantity oi Witter n ill continue to flow through the slotted extensions i3, 14, l5 of the meinv inlet ports, which ilow of Water constitutes the titer-wesh for the part refilling of the closet-howl. As the pistone-.el e 5 continues its downward ino'iernent after having closed tne rnein inlet ports to cut of the :nein ilow of water, the slotted extensions 13, i4, l5 ere closed in succession, rnelrin e gre-duel end srnell iinsl closing es the sei piston^-elfe 5 is. forced by the ressure of the Weiter mithin the pressure e einher of the cylinder 3 onto its seet 6', to close the' mein outlet 6. This gradual seating of the piston-:ni e 5 and cutting oli' olf the liow of Water to the closet-bo\\l, ohzietes 'ell noise and er en the pipes.
