VALVE-CONNECTION FOR HOPPER WATER-CLOSET'S.
SPECIFICATION forming part of Letters Patent No. 382,820, dated May 15, 1888.Y
i Application filed April 18, 1887. Serial No. 235,181. (No model.)
To a/ZZ whom it may, concern/:
Be it known that I, GEORGE F. MARSHALL, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Valve Connections for Hopper Water-Closets, of which the following is a specification.
My invention relates to valves for supplying iiushing-water to hopper water-closets. It may be applicable in other connections, however.
The invention has for its object the devising which is an adjunctof the usual hopper-closet, may be connected with the closetin such manner as that the expense and inconvenience of a specially prepared inclosure or protecting structure are dispensed with and allliability of the valves freezing is obviated.
A further object is to render the valve easily capable of repairs without the necessity of disturbing the valve-casing or other parts of the valve structure, which, as ordinarily constructed, can only be gotten at for repairs by annoying and expensive excavations.
My invention will be hereinafter described, and is shown in the accompanying drawing, and the features of novelty for` which Letters Patent are desired are pointed out in the claims at the end of this specification.
In the' annexed drawing, forming a part of this specification, I show in a central vertical section a structure which illustrates my invention and its application to a common hoppercloset.
Referring to the drawing, A indicates the hopper-closet; B, a soil-pipe, and C the pipe.
adapted to supply the flush-water to the closet.
D indicates an elbow, which connects at the end a with the water-supply under pressure, and whose opposite end, b, is -screw-threaded to receive the extension pipe-section E. The coupling D is preferably made of brass, andin the act of casting is formed with a constricted portion, c, whereby a suitable valve-seat is provided. Above this constricted portion c-the elbow is enlarged, as shown at d, in order that when the valve is raised off its seat it will not materially interfere with the inilowing water- Supply F also represents an extension pipe-section,
`between which, and the lower pipe-section, E-
both of whichY pipe-sections are preferably of wrought-iron-there is located the T-coupllng G, also of wrought-iron, into which is secured the brass coupling device `H, which receivesl the pipe C, which supplies the closet with the flush-Water. 'Io the top ofthe extension pipesection F there is secured,`by screw-'threads or otherwise, the casing K,through which passes the valverod L, and which contains the conipression-spring M. The casing K is preferably of brass, and is provided at its upper end with a vertical `flange, c, furnishing a seatingsurface for the cap N, which is held in.position by screw-threads or otherwise, and through which the valve-rod .L projects, and whose upper end is supplied with a rocking lever, O, of wellknown type, whereby the valve-rod is operated for opening andl closingthe valveP. rlhe external circumference of the flange e may be screw-threaded to receive the usual plate,
Q, which is adapted to be secured to the closet-v seat by screws and nuts, or otherwise.
The valve-rod L is provided with an enlargement-at its lower end, upon which is seated the disk f, upon which reststhe compression-spring M. The disk f is also adapted to bear upon the upper end of the extension pipesection F, and it is composed of material adapting ,it for service as a packing to preventthe passage of water into the casing K, this being one ofits principal functions.
The valve P is secu red upon the lower end of the rod R preferably in the manner shown. The upper end of the rod R is enlarged and provided with a screw-threaded depression,'g, corresponding to the screw-threaded depression h in the enlarged lower end of the rod L.
ciently deep to avoid all liability from the effects of freezing. The distance between the top of said elbow D and the bottom ofthe casing K, when the latter is placed in position upon the closet-casing, may vary with different localities, and it is one of the purposes of my invention to render a structure such as herein described readily applicable under any conditions that may arise. I therefore provide t he extension pipesections E and F, with which the Tv coupling G (1o-operates, as well as the eX- tension rod-section S, of lengths suitable for the special serviceso that while in some cases the said extension pipe-sections and extension rod-section may be a few feet in length in other cases they may be many times greater in length, so that practically it isimmaterial, within certain limits, what the distance may be between the valve-seat coupling and the means for operating the valve-rod.
Under my plan of 'construction the valve may be reached for repairs, notwithstanding it may be located beneath thesurface of the ground a considerable depth, without any excavation or tearing up of the structure. This is accomplished by disconnecting the cap N at the top of the casing K and withdrawing the rods L, S, and R with the attached valve, the diameter of the conduit between the valve-seat and the top of the casing K being suflic'ient to permit the withdrawal of the entire interior mechanism. By this means repairs maybe cheaply and quickly accomplished.
Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is
1. In avalve-connectionforsupplyingtlushwater to hopper water-closets, the combination of the seat-plate Q, having the screw-threaded central aperture, the cylindrical casing K,hav ing the screw-th readed ange e, screwed into the aperture of the plate, the cap N, screwed into the upper end of the casing, the valve-rod sliding through the cap, and the rocking camlever bearing against the cap and pivoted in the upper end of the valve-rod, as shown, and for the purpose specified.
2. In a valve-connection for the flush-water in hopper water-closets, the seat-plate Q, the guide-cap N, the upper casing, K, and thelower casing, E, their intermediate couplings, F and G, the latter having the hopper-connecting pipe H, and the supply-coupling D atthe lower end of the lower casing, having the seat-forming constriction c of curved walls, forming the ralreseat centrally in line with the guideway in the cap, and having the drailrpipe T above said constriction and the supply branch a below said constriction, in combination with the elongated valve P, having curved walls, and its con necting-rod, whereby the said cap forms the guide for the valve-rod and the said curved constriction forms a .centering guide and seat for the valve, as set forth.
