To all whom it may cancer-n:

Be it known that I, EDwIN L. KNIGHT, a citizen of theUnited States, residin g at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Tater-Closet Valves, of

, which the following is a specification.

This invention relates to that class of water-closet valves which are adapted for insuring, on being once lifted from their seats, a primary and extensive flush of water through the service-pipe, and also a supplemental and less extensive fiush after said primary fiush has ceased; and the invention consists in the construction and combination of the Various parts, all substantially as will hereinafter more fully appear, and be set forth in the claims.

In the accompanyin g drawings my improved Valve is illustrated, similar letters of reference therein indicating corresponding parts in all the Views, and Figure 1 is a central Vertical seotion of the Valve as applied for operation in a tank, the said Valve being shown in a position as just raised from its seat to its full height and ready to close. Fig. 2 is a section of the Valve similar to Fig. 1, but drawn about full size and shown as closed. Fig. 3 is a horizontal section of the valve, taken on the planes indicated by the line a; x, Fig. 2. Fig. 4= is a perspective view in detail, partly broken away for better illustration of a part of the Valve hereinafter referre'd to; and Fig.

5 is a plan and projection thereof of an abutment-nut, hereinafter referred to.

In the drawings, A represents the Valveseat located in the bottom of the tank B, to which the service-pipe is to be attached, and a lateral hollow extension a is integrally formed With said Valve-seat for the overfiowpipe b, as usual.

O represents the Valve, and cl and e the lever and chain connection for its operation. The Valve is formed in tw o parts, the upper member of which comprises a cylindrical body f, having in its bottom an upwardlyfiaring chamber g and an upwardly-extended axial spindle h, which spindle is also downwardly projected a short distance in an eX- tension h2 below the plane of ,the bottom of said cylindrical body, and the lower member is essentially a disk for directly covering the Valve-seat, movable longitudinally within given limits on said extension and having Vertical openings therethrough. The said spindle from its lower extrem'ity to within a short distance from its upper end is hollow, the bore thereof for the greater portion of its length from its upper end being of a diameter, as at i, to fit the guiding-spindle D, which is supported in the axial line of and from the Valve-seat casting in the manner usual in Valves of this class, and from the lower end of said spindle its bore is of slightly increased diameter, as seen at j. In the side wall of said' spindle is a lateral and downwardly-extended passage k, leading from the part z' of the spindle-bore to the fiaringlower chamber g, the walls of the spindle at one side being laterally distended to afford sufiicient stock within which the said passage may be formed, and an adjusting-screw Z is provided for a regulating impediment to the passage of water through said passage, as will hereinafter appear.

The lower member of the Valve comprises a sleeve m for loosely surrounding the spindle-extension 712, and a collar n concentric therewith and supported therefrom by radial arms p, and preferably in a lower plane than said sleeve, with openings between them, and said'collar of itself having its perimeter sufficiently extended or being provided with a supplemental part, as a washer q, of leather or other compressible material, is, in the operation of the valve, to directly rest upon the valve-seat, closing the passage thereof. As shown, .the attachment of the washer to the said collar is by forming a peripheral fiange r on the upper edge of the collar, the periphery of the collar below said fiange being screwthreaded' for receiving a nut 8, between which and the said fiange the washer is bound.

A lifting-abutment t is provided on the lower end portion of the spindle for the purpose, after the upper member of the Valve has been raised a certain distance by the lever, of also lifting the lower member from its seat, and said lifting-abutment is to be preferably adjustable longitudinally of said lower spindie-extension, whereby the degree of separation of the members of the Valve at the time of its being lifted may be Varied, a simple and practical method of securing such ad- IOC j ustablo feature being by forming screwthreads on the spindle-extension 71-2 and tapping the said abutment 25.' The said liftingabutment t is to be recessed, as at a, or perforated, so that at no time under any position thereof in the operation of the valve relative to the opening o between the sleeve m and collar n will said opening` be closed. l

The operation of the valve described is as follows: Assuming the same to be closed, as in Fig. 2, on Operating the lever the upper member of the valve is raised a short distance before its liftin g-abutment t comes in contact with the lower member, as by striking against the radial arms p thereof, when the latter is also raised from the valve-seat, permitting the large flow of water, and it will be observed, Fig. '1, that the valve has been lifted, so that the part of the spindle-bore i of less diameter is entirely above the upper end of the guiding-stem D, whereby the, spindlebore may be filled with water. As the valve, under its weight and aided by the waterpressure from above, settles, the valve-seat A is soon covered by the lower member of the valve, and the major fiush ceases, but the minor fiush continues,water fiowing from the tank through the opening v between said` sleeve m and collar 'n until the upper member of the valve descends and its body f rests upon the washer q, when the latter flush ceases. The water in the spindle-bore forms a resistance or cushion, being expelled only through the passage k, and therefore the minor fiush will be of considerable duration, the extent of which may be regulated by the screw Z on the one hand and on the other by the distance the lifting-abutment is normally placed from the under contacting side of the lowermember of the valve, and said abutment may be, if desired, screwed up against the arms p, and in that event but 'one Wash will be secured from one raising of the valve.

Vhat I claim as my invention is- 1. In a water-closet Valve, the combination of an upper weighted member to which the lifting-Chain is attached, with the lower member loosely connected thereto and having a Vertical play in dependently of the upper member and provided with an opening through which the minor fiushiof water passes, and

2. In a water-closet valve, the combination of the upper weighted member provided with a lifting device at its lower end and the lifting-chain attached to it at its upper end, with the lower perforated vertically-movin g member which has an independent Vertical play or movement of its own and which is raised by the lifting device, the valve-seat, and a meansfor retarding the closing of the upper weighted member after the lower perforated member has become seated upon the valveseat, substantially as specified.

3. The combination, with a valve-seat and a guiding-spindle supported therefrom, of a valve comprising two members, the upper of which consists of a body and an upwardly and downwardly projected hollow spindle open from its bottom, the bore of which is of two diameters, substantially as described, and having a laterally and downwardly extending passagek, and a lifting-abutment t on said lower spindle-extension, and the lower member consisting, essentially, of an open-work disk adapted for a Vertical movement with relation to said lower spindle-extension, substantially as described.
