To all whom it may concern:
Be it known that I, DAVID F. GARvEY, a citizen of the United States, and a residentl of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Flushing Apparatus, of which the following is a full, clear, and exact description.
The invention relates to flushing apparatus for waterV closets and its object is to provide apparatus of that class in which water is held under pressure of air in a closed tank with a j et by which water from the supply main will be used to accelerate the flow to the closet when the controlling valve is open. Another object of the invention is to provide an improved apparatus of this class.
The drawing is a side elevation of apparatus, parts being shown in section.
The flushing apparatus is illustrated in connection with a water closet bowl l of any ordinary or suitable construction and comprises a closed tank 2, a pipe 3 for delivering water from the tank to the bowl, a suitable valve l usually of the type which4 is self closing after remaining open for a predetermined period, and a supply pipe 5 which is connected to the water supply main. Supply pipe 5 comprises a member 6 which eX- tends downwardly through a portion of the vertical member 3 of the pipe 3 to serve as a jet by which the pressure of the water in the water supply will be utilized to force water to the bowl. Pipe 3a is greater in diameter than the pipe 6 so that during a flushing operation water from the tank and from the supply 5 will flow to the bowl. Pipe 3 comprises a horizontal member 3b which is connected to the vertical member 3 by a suitable fitting 7 and a downwardly eX- tending vertical member 3c which passes through the top of the tank 2 and has its lower open end terminating near the bottom of the tank.
In operation, the valve 4l will be normally closed and water will be delivered through the pipe 6 into the member 3a from which it will flow through members 3b and 3c and be discharged adjacent the lower end of the closed tank 2. As the column of water rises in the tank, the tank, the air between the column and the top of the tank will be compressed so that when the valve 4 is open to flush the closet, air under pressure will cause the water to flush the bowl. During this flushing operation, the water from pipe 6 will act as a jet which will supplement the pressure of the water from the tank 2 so that the flushing effect will be increased thereby.
If the air pressure in the tank should be dissipated, the water will be siphoned from the tank by the action of the jet 6.
In practice, it has been found that when the tank is not emptied for a considerable period, the air pressure will decrease and that by using the jet pipe 6 the water will always be forcibly drawn from the tank and delivered to the bowl under pressure. It has also been found that-by extending the pipe 3C so as to deliver the water in a downwardly direction, there is less tendency t0 mix the air and water and as a result an effective air pocket will always be formed.
The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.
I-Iaving thus described the invention, what I claim as new and desire to secure by Letters Patent, is:
l. In a flushing apparatus, the combination of a closed tank, a flush-pipe connected to deliver water to and from said tank, a valve for controlling the discharge of water from the flush-pipe, and a supply pipe provided with a j et extended into the flushpipe to force water through the flush-pipe and toward the valve.
2. In a flushing apparatus, the combination of a closed tank, a flush-pipe connected to deliver water to and from said tank comprising a vertical member, a valve for controlling the discharge of water from the flush-pipe and a supply pipe provided with a vertical jet-pipe in said vertical member and discharging water downwardly, to force it toward the valve.
3. In a flushing apparatus, the combination of a closed tank, a flush-pipe connected to deliver water to and from said tank, and comprising a member extending downwardly and having its lower end near the bottom of the tank and open, a valve for controlling the discharge of water from the flushing pipe, and a supply pipe connected to deliver the tank and open, a valve for controlling water/into the lushfpipe and force it toward the discharge of water vfrom the flushing 10 the valve. piping-andra supply-pipe provided-with a jet Y 4;. In a, flushing apparatus, the oombinain the flush-pipe to Siphon water from the 5 tion of a closed tank, a flush-pipe connected tank through said member and force it toto deliver water to andffromsaidtank, land ward the valve. comprising a member extending downwardly and having its lower end near thebottom of DAVID F.
