Application filed June 9, 1925. Serial No. 35,872.
To all whom it may concern:
Be itknown that I, PHILIP Haas, a citizen of the United Statesyresiding at Dayton, in the county of lilontgomery and State of Ohio, have invented certain new anduse'tnl Improvements in Inlet-Valve Mechanism for Flush Tanks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention consists in the novel features hereinafter described, reference being had to the accompanying drawing which illustrates one form in which I'have contemplated embodying the invention and which has been selected by me tor purposes of illustration, and the said invention is fully disclosed in the following description and claims. 7
The object of my invention is to provide an inlet valve for flushing tanks of extremely simple character, which can be cheaply constructed and will be certain in operation, the parts of the valve mechanism being readily accessible and the separate parts thereof readily replaceable in case of wear. My invention also contemplates-the operation of the valve by means of a float lever which is demonntable with respect to the valve mechanism proper, so thatit may be instantly removed and replaced by hand when desired.
Referring to the accompanying drawing, Fig. 1 represents afinsh tank provided with a flushing valve embodying my invention, a portion of the tank being broken away to show the location of the valve and its pipe connections.
Fig. 2 is an enlarged sectional view the valve mechanism and the adjacent portion of the valve operating float lever.
Fig. 3 is a vertical section on the line 3-43 otFigzQ. U M
Fig. 4 is an enlarged detailed vie'uypartly in section, showing a 'removable'plug'forming part of the valve mechanism and carrying the removable inlet valve seat.
Fig. 5 is an enlarged detailed view partly in section, o:f the inlettvalve.
Fig. 6 is a detailed view also enlarged, of a portion of the valveac'tuating float lever adjacent to the valve.
In thesaid drawings, 1 represents a flush tank 'irovi' ded with removable cover, 2, and having an outlet" for the flushing pipe,
3, provided with any usual or preferred form of flushing valve mechanism, which is notshown herein as the same forms no part my present invention. 4c represents the water inlet tiiipe connected with the tank by a litting'indicated at 5, in any usual or well known manner, to which a vertical pipe, 6, is connected. andextends to a point near the top ottl'ietank where the inlet valve is loc'a"ted,*the entire inlet valve or at least'the u ppcrportion or the same being preferably above the water level so that access may be had'toitfor the purpose of removing and ieplacing "parts without wetting the fingers. t represents a downwardly extending discl'i-arg'e pipe from the valve casing, terminating a short distance above the bottom of the tank, which is preferably employed tor'delivcrinp; the water from the 'valve'casing to the tank without undue noise. The normal water level in the tank is indicated in Fig. 1. by a dotted-dine. 8 represents the valvepcasin; which is divided by-an' angular partition, 9, into an inlet chamber, 10, and an outlet or disch'arg'echamber, 11, connected by an aperture, 12, in a horizontal portion of the said partition. The upper part ofthe valve body provided with a threaded aperture,
1%, 00-21 'ial withthe aperture, 12, to receive the threaded portion ofa removable plug indicated at 14 and shown in detail in Fig.
4.; Thisplug is provi'ded at its upper end w1th a polygonal portion, l5,'and a shoulder,
'16, extending beyond the threaded portion and-providedwith a washer, 17, to engage the upper face of the valve casing and make a tight 101111; therewith. The plug is also n'ovi'ded .-w1th a' central bore, 18, the lower portion of which is threaded to .receive a removable collar, 19,'the lower end of which is preferably rounded to form the valve seat, 20.,for the inlet valve. r I
Thecoll'ar, 1-9, isalso. provided with a po l ygonal shoulder portion, indicated zit-21, between" which 11'1'Cl" the'flo'wer face of the pluga washer, 22, is "provided, and held in position with respect tothe plug. The removable collar, ISL-is preferably made of .a
material which will not be affected injurionsly by the water passing through the inlet valve mechanism at the particular point of I installation. The character of water varies greatly and themetal which is not affected by the waterin one installation, may-be utterly useless inanot-her. It is for this rea son tlrat'ltpreferto make the collar, 19, as a separate part and attach it to the plug .in the manner shown, so that these collars may be made up in different metals, as brass, Monel metal, nickel-silver, or any other suitable material, and a collar of the proper and most desirable material to withstand the particular water with which it is to be used can thus be supplied with any of my inlet valve mechanisms. The plug, 14:, is also provided with an annular groove indicated at 23, the inner wall of which is pierced with a plurality of apertures indicated at 2 1, communicating with the interior of the bore, 18. The plug, 14, is screwed into the threaded aperture, 13, at the top of the valve casing, and
screwed down so as to bring the washer, 22, in engagement with a seat indicated at 25, on the upper face of the horizontal portion of the partition, 9, surrounding the aperture, 12, forming a tigl'it joint at both points so that the inlet chamber, 10, will then communicate with the discharge chamber, 11, through the groove, 23, apertures, 2st, and a central opening in the collar, 19, under the control of the inlet valve.
The bottom of the valve casing is provided with a bearing aperture, 26, in axial alignment with the aperture, 12, to receive the inlet valve illustrated in detail in Fig. 5, which comprises a metallic cylindrical valve body or plunger, 27, having an axially aligned recess in its upper end, in which is locatedthe valve proper, 28, formed of rubber, fibre, or other suitable material, of a diameter suitable to engage the valve seat, 20, and close the aperture through the collar, 19, and the valve body is preferably provided with a conical lower end indicated 29. The valve body is also provided with a pair of depending lugs indicated at 8030, carrying a pivot pin, 31, which is adapted to be detachably engaged in a recess, 32, in a flattoned end portion, 33, of a float actuated lever, Set, the outer end of which is provided with a float indicated by dotted lines in Fig. 1, at 35, and which is preferably of the kind described in my former application for Letters Patent of the United States, filed March 21-, 1925, and given Serial No. 17,856, although any other form of float mechanism may be employed in connection with this inlet valve mechanism. l/Vhen the recess, 32, of the float lever, is in operative engagement with the pivot pin, 31, the lever will be in position to operate the inlet valveand when the float is in raised position as shown by dotted lines in Fig. 1, the lever will engage the conical end, 29, of the valve body, 27, and force it upwardly so that the valve proper, 28, will engage the valve seat, 20, and shut off the flow of water against the pressure thereof. It will be noted that the point of engagement of the conical end of the valve body, 27, is closely adjacent to the pivot pin 31, thus giving a sufficient leverage to the float lever to insure the closing of the valve against any water pressure that would be used in connection with a float tank of this character.
The valve body, 27, is preferably made of Tobin bronze or nickel silver, so that it will not corrode and thus become stuck in the bearing aperture, 26, of the valve casing, and the pin, 31, will preferably be made of Monel metal so that it will not be affected by the water. The correct operation of the inletvalve mechanism of a flush tank is of great importance to the successful operation of the flushing system in which it is used. In the ordinary inlet valve as heretofore constructed. the valve seat frequently becomes corroded or eaten away by some material in the water, so that the valve does not correctly seat and leakage produces waste of water and frequently unnecessary flushing action, with the accompanying l'lUlF-Jt and useless waste of water, which on metered service or in congested residence districts is extremely objectionable and expensive. rinot-her difiieulty in the ordinary use of inlet valves is the wearing of the seat engaging valve proper, which usually requires the oflices of a skilled plumber to correct. Another source of dith'culty in the operation of inlet valves is the sticking of a valve where a movable valve of the olunger type, :ch as is shown in the accompanying drawing, is employed. I obviate all of these di'liiciih ties by providing the removable collar, 15), which is especially designed to withstand the particular water with which the device is to be used and therefore will operate for a very extended period without any breaking down of the valve seat, 20. Should thishappen, it is only necessary to unscrew the plug. 1st, which is readily accessible, and replace the collar, 19, with a new collar. The valve body, 27, is also made of a material which will withstand the action of the water with 'which it is to be used, and in (use it should become necessary to remove the valve body, 2?, or the packing or valve proper, 28, this can be readily done by opening the flush valve and emptying the tank, pcrmitt ing the lever, 34, to fall, and then detaching the lever from the pin, 31, which will permit the valve body, 27, to drop out and a new one can be pushed up into its place, and the lever, 3st, restored to its operative connection with the pin, 31. Additional collars, 19 and valves, 27, (with the valve proper or packing, 28) will be furnished with my improved inlet valve mechanism for the purpose of renewing these parts should it become necessary, and this can be done at any time by an ordinary householder without calling in skilled labor.
The valve body or plunger is also provided with a conical end portion, 29, as before described, and the upward pressure exerted by lltl the float lever, 3 will always be substantially axial with respect to the said valve body or plunger, so that there will be no tendency for it to bind in its vertical movements. If desired, the plunger valve can be removed by moving it upwardly through the aperture, 12, by removing the plug, 14:, and reaching the valve by sticking a pin or sharp implement in the rubber packing, 28, or otherwise lifting it out of its guiding aperture.
lVliat I claim and desire to secure by Letters Patent is:
1. Inlet valve mechanism for fiush'tankS, comprising a valve casing provided with an interior partition having an aperture there in, said casing having apertures in its upper and lower portions co-axial with said partition aperture, a plug fitting in the upper aperture in the casing and closing the same and having a sealing engagement with said partition, said plug having an interior bore and lateral openings communicating with the bore and with the interior of the valve casing, a collar detachably secured to said plug extending through the aperture in said partition, and provided at its lower end with a valve seat, a plunger valve engaging in the bottom aperture of the casing, having a recess at its upper end co-aXial with the valve seat and a removable valve proper seated in the said recess for engaging said valve seat .and movable float actuated means having portions operatively engaging said plunger valve.
