SUPPLY VALVE FOR THE FLUSHING TAN-KS or WATER GLOSETS, &c. No. 317,055. Patented May 5, 1885.
UNITED STATES PATENT OFFICE.
HENRY O. W'EEDEN, OF BOSTON, MASSACHUSETTS.
SUPPLY-VALVE FOR THE FLUSHING-TANKS OF WATER-CLOSETS, dc.
SPECIFICATION forming part Of Letters Patent NO. 317,055, dated May 5, 1885.
Application filed September 11, 1884. (No model.)
To all whom it may concern.-
Be it known that I, HENRY O. WEEDEN, of Boston, in the county of Suffolk and State of Massachusetts, a citizen of the United States, haveinvented certain new and useful Improvements in Supply-Valves for the Flushing- Tanks of Water-Closets and SimilarStructures, of which the following is a specification.
I The object of my invention is to provide, in connection with the valve ordinarily used for opening and closing the passage from the supply-tank to the water-closet, urinal, or similar structure with which it is connected, appliances whereby, after the valve has been raised from its seat and the outflow of water has commenced, the fall of the valve may be.
gradual or retarded, so as to allow a larger quantity of water to escape for flushing purposes than is the case where the valve is allowed to drop unchecked, as is now ordinarily done. By my present invention this is accomplished automatically, as will now be described.
In Figures 1 and 2 of the accompanying drawings I have represented in vertical section two forms of apparatus, each embodying my invention.
A represents the outlet and valve-seat, as ordinarily constructed and located, at the bottom of the flushing-tank B. The valve 0 may be that ordinarily used, as shown in Fig. 1, or it may be provided with a supplemental disk or plate, a, as shown in Fig. 2, the purpose of which will be explained hereinafter.
For retarding the descent of the valve I provide a chamber, D, within which the valve is arranged to travel vertically, and within which the valve itself or the supplemental disk or plate 0 fits with substantial tightness, but not so tight as to cause any material friction against the interior of the vacuum-chamber. It is convenient to have the rod by which the valve O is raised pass through a hole in the top of the chamber, fitting therein substantially tight, but not so as to cause material friction.
The operation of the device is as follows:
In order to flush the closet or other similar- .let continues open until the valve falls and closes it. In falling the valve has to displace the water below it in a chamber, D, which is without air opening in its top, and its fall being retarded allows a larger amount of water to escape from the-tank, and also a slower descent of the valve than if it were not incased in or surrounded by a chamber, as shown.
The time of the descent of the valve, and consequently the duration of the flush, may be regulated at pleasure by varying the relative size of the valve and the chamber D. If this chamber, for convenience, require to be made of greater cross-section than the valve, thelateral area of the valve within the chamber may be increased by forming the valve with an enlargement, c, as shown in Fig. 2.
To lift the valve I prefer to employ a rod, as shown in Fig. 2 but a chain, wire, or cord may be substituted. (See Fig. 1.) It is obvious that the valve or the valve and disk does not require to be fitted so closely within the chamber D as to form a piston or plunger 7 therein; but sufficient space should be left bebetween these parts to permit of the passage of the water between the edges of the valve and the walls of the chamber when displaced by the fall of the valve.
I am aware that valve-retarding devices have already been shown and used prior to my invention, and I make no claim to them broadly. My present construction differs from those heretofore used, in that it greatly reduces the number of parts, and consequently the efficiency, simplicity, and cheapness of the apparatus.
I claim 1. In combination with a flushing-tank and 90 its outlet, a valve for opening and closing the outlet, a chamber without air-opening in its top and slightly larger in cross-section than the valve, and surrounding it and communicating with the tank, as. shown, and a rod or 9 5 chain, F, attached to the valve, whereby it may be raised Within the chamber to open the In testimony whereof I have hereunto sub- IO outlet, all substantially as herein set forth, scribed my name this 8th day of September, and for the purpose herein specified. A. D. 1884.
2. In combination, the valve 0, the chamber D, larger than the valve, as described, 7 and Without air-opening in its top, and a lifting'device, E, attached to the valve, whereby it may be lifted to cause the flush, all substantially as set forth.
