VALVE FOR WATER-CLOSETS.
SPECIFICATION forming part of Letters Patent No. 371,431, dated October 11, 1887.
Application filed December 30, 1856. Serial No. 229,505. (No lllOllll.)
To all whom it may concern:
Be it known that 1, WILLIAM S. COOPER, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Valves for ater-Closets, of which the following is a specification.
My invention consists of certain improvements in the construction of valves for the supply of water to water closets which have a siphon-discharge, or are so thoroughly flushed as to clear out the sealing-traps or standing wafer-pools of the closet, the main object of my invention being to so construct the valve as to insure the proper filling of the traps or pools after the siphon or flushing action has ceased.
In the accompanying drawings, Figure l is a longitudinal section, partly in elevation, of a water-closet valve constructed in accordance with my invention, the valve being shown in the open position; and Figs. 2 and 3 are sections of part of the valve, showing the action as the valve is being closed.
In Fig. 1, A represents the discharge-casing of the valve, which is secured to the casing A of the tank in any'suitable manner, and contains an internal bucket, B, between which and the outer casing is a passage, m, of sufficient area for the flow of water when the valve is fully opened.
The valve D has a packing-ring, a, which is adapted to a seat, y, around the inlet-opening or mouth of the casing A, and cuts off the flow of water when the valve is lowered to said seat, and the valve has a tubular stem, 1), which is fitted loosely to a guidepin, d, in the bucket 13, and carries at its lower end a plunger, F, having a loose packing-ring, f, confined between upper and lower flanges, i i, of the plunger. This ring offers no obstacle to the free rise of the plunger, as the ring during this movement rests on the lower flange, i, so that water can pass freely around the upper flange, 1', and over the ring into the bucket B; but as soon as the plunger commences to descend the ring is caused to bear against the beveled under face of the upper flange, 11, whereby the ring is forced outward against the side of the bucket, and the escape of water around said upperflangeisprevented. Thewatertrapped in the lower portion of the bucket is thus caused to pass upward between the pin (1 and stem 1) of the valve and escapes through an opening, an, in the hub g of said valve, the area of this opening determining the rate of speed at which the valve is permitted to close to its seat after having been elevated and then released. A perforated plate, a, at the upper end of the hollow stem b, serves to prevent the access to the opening m of particles so large as to have any tendency to clog said opening, so that interference with the operation of the valve, due to this cause, is prevented.
\Vhen the valve is fully opened, as in Fig. 1, free flow of water into the closet is permitted, a large volume of water thus entering the closet and causing the siphon or flushing action in the discharge-pipe of the same. This siphon or flushing action draws all the water from the bowl and traps or pools of the discharge-pipe; hence it is important that after the action has ceased there should be a flow of water into the closet sufllcient in volume to insure the proper filling of all the traps or pools. This object I effect by providing the valve with a downwardly-projecting flange, s, the lift of the valve being such that the bottom of said flange is raised above the seat 1 to a sufficient extent to insure the desired free flow of water to the closet in the first instance for siphoning or flushing purposes. As the valve descends, the flange enters the mouth of the dischargeeasing a,- but as the external diameter of the lower portionof the flange is slightly less than the internal diameter of the mouth a restricted flow of water to the closet is permitted, as shown in Fig. 2, this flow being somewhat increased in volume as the valve approaches the limit of its downward move ment, owing to the fact that the flange s is slightly contracted in diameter at and near its upper end. (See Fig. 3.)
Although I prefer to form the cscapc-opening at in the hub of the valve, as shown, on account of the simplicity and chcapness of this construction and the comparative inaccessibility of the opening to foreign particles tending to clog it, other means of regulating the discharge from the bucket on the descent of the plunger may be used in carrying out my invention. Forinstance,theplanshowninmy application filed March 31, 1884, No. 126,132, or that shown in my application filed July 26,
1886, No. 209,090, maybe adopted for the purpose, or other known means of restricting the speed of movement of the valve in closing may be used.
I claim as my invention- 1. The combination, in a water-closet-supply valve, of a dischargeehest, a valve constructed to close the mouth of the chest and having a depending flange or projection some what less in size than the said mouth, and means for raising the valve so that the lower end of the flange is above the top of the mouth, whereby when thevalve is first opened a full how of water through the chest is permitted, which flow is diminished when in the closing movement of the valve the flange of the same enters the month of the discharge chest, the
diminished flow continuing during the ren1ain der ot'the movement, all substantially as specified. Y
2. The combination, in a water closet-supply valve, of a dischargechest, a valve constructed to close the mouth of the chest, and having a depending flange less in size than said mouth, but constructed to enter the same and restrict the flow as the valve commences to close, and means, substantially as described, for retarding the closing movement of the valve, all substantially as specified.
3. The combination of the discharge-chest 'and the controlling-valve having a tapered 5. The combination of the dischargechest and its trapping-bucket, the valve having a hollow stem with plunger at the lower end and discharge opening at the upper end, and the perforated plate beneath the discharge-opening, all substantially as specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing Wit nesses.
VVILLI AM S. COOPER.
