JAMES H. MAHONEY, OF WORCESTER, MASSACHUSETTS.
FLUSHING-VALVE.
Specificeton of Letters Patent.
Application filed May 12, 1910.
Patented Mar. 14, 1911.
Serial No. 560,920.
To all whom it may concerns e Be it known that I, JAMES H. MAI-IONEY, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvenents in l*`lushing-Valves, of which the following is a specification, reference being had to the acco'npanying drawings.
This inventon relates to improvements 111 fiushing valves for fiush tanks used in connection With water closets.
The object of the invention is to provide a valve of this character in which the vacuun is formed, not by the suction created by the flow of Water through the valve, but by the Water passing through the top of the valve, forcing the air out before it, this object being attained by the peculiar construction of the valve and its arrangement with respect to the water valve in the tank.
With the above and other objects in View, the invention consists of the novel Construction, combination and arrangement of parts, hereinafter fully described and claimed, and illustrated in the accompanying drawings in which Figure l is a sectional View through a flush tank showing my improved valve arranged therein; and Fig. 2 is a detail sectional View through the valve. Fig. 3 is a detail sectional view of the forked guide, taken on the plane indicated by the line 3-3 of Fig. 2.
Referring more particularly to the drawings 1 denotes a tank which may be a flush tank or box of a water closet, or any other tank or container used for flushing purposes.
2 denotes the flush pipe which is arranged vertically in the bottom of the tank and is adapted to have its upper edge 3 serve as a valve seat. The valve 4: comprises an inverted cup-shaped casng which is preferably of cylindrcal form and provided with an open bottom so that it telescopes the upper portion of the pipe 2. The closed top 5 of this cvlindrieal casing forms the valve proper, and arranged upon its bottom face is a packing member 6 adapted to engage the valve seat 3 When the valve is lowered or in its closed position. The packing member 6 is in the form of a ring and is arranged on a reduced end or shank 7 of a forked guide 8 which slides within the pipe 2 and guides the cylindrical valve 4: in its Vertical movement. The stem or shank 7 passes through a central opening in the top 5 of the valve and is screwed or otherwise secured in a head or block 9, which letter .may serve as a weight.
The valve may be actuated by any suitable means but I preferably enploy a lever 10 fulcrumed intermediate its endsat 11 on a suitable support and having at its outer end a suitable handle and its inner end connected by a link 12 to the top of the valve. If desired, I may employ in connection With the valve and its level' a checking device for retaining the valve in its raised or opened position until the tank is empty, such device consisting preferably of an angular lever or bell crank 13 fulcrumed at its angle, as shown at 14, and having a long arm carrying a float 15 and a short arm or head 16 which serves as a cam and adjusts itself under the stop lug 18 provided on the inner end of the lever 10, which stop lug keeps the valve open.
19 denotes an overflow tube or pipe of an inverted U-shape having one of its legs in conmnicntion with a horizontal branch tube or pipe 20 projecting laterally from the lower portion of the fiushing pipe 2, the other leg of the tube or pipe 19 being open andkterminating close to the bottom of the tan i In operation it will be seen that when the lever lO is actuated, the valve 4 will be raised allowing the water within the tank to flow downwardly through the flush pipe '2, forc-ing the air before it, thereby creating a vacuum. The siphoning action thus started continues unt-il the tank is empty and the vacuun is broken by air entering through the open bottom of the valve 4: providing the valve is held elevated. The flow of water will cease when thevalve drops on the seat regardless of the siphonic action, as the closing of the valve closes the opening to the bowl. In this respect it is different from siphon valves. This valve does not depend on having air enter the vacuum in order to break the siphon or sto-p the flow of water to the bowl.
When no checking device is employed the valve must be held elevated by hand, but
When the checking device shown in Fig. 1
l'om the o'egoi'g it will he seen that this valve is the combina-tion of a slow closing and siphoning VLlVG and is especially ada pted for low tanke used for fiushing water closets and the like.
Val-tous changes in the form, proportion and ar'angement of parte may he made within the spirit and soope of the invention.
Having thue described the invention, What is claimed is:
The heren described flushing appamtus conprsng a tenk, an npright flushing pipe extendng through the bottom thereof, the said fiushing pipe being provided With an overfloW pipe connected thereto, an inverted cup-shaped valve arranged over the tip-per portion of said flushing pipe, e fo'ked guide vertieally movable in the upper portion of the said fiushng ppe and provided at its uppo' end With a threaded stud extendng upwzu'dly through the top of said valve, a Washer between the top of the valve and the upper end of the said forked guide, and a Weight on the top of the said valve and provided With a threaded opening engaged by the said stud, the said Weight, guide, and valve being provided With means for the attachment thereto of Et rod to operate the said valeve, the said Weight serving to normally close the valve on the uppe' end of the said fishing pipe.
In testimony Whereof I hereunto afiix my Signature in the presence of tWo witnesses'.
