PATRICK HARVEY, OF CHICAGO, ILLINOIS.
SIPHON-JET-CLOSET-OPERATING D E VICE.
SPECIFICATION forming part of Letters Patent No. 597,499, dated January 18, 1898.
Application filed February 24, 189 '7- fierial No. 624,838. (No model.)
To a/ZZ whom it may concern:
Be it known that I, PATRICK HARVEY, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Siphon Jet Closet Operating Devices, which are fully set forth in the following specification, reference being had to the accompanying drawings, forming a part thereof.
The purpose of this invention is to provide improved means for operating a so-called siphon-jet closet-that is to say, a watercloset in which the bowl is evacuated by siphonic action, such action being initiated by a forcible jet of water injected upward through the discharge-limb of the trap, which is the up-limb of the siphonic discharge-passage.
In general the invention consists in means for supplying the jet from a source of Water under pressureusually the watersupply system of the house-and means for flushing the closet from a low tank; or supply-box which would not afford the necessary pressure for the jet, thus permitting the use of such low tank without sacrificing the advantages of the siphon-jet mode of action in many situations where a tank sufficiently elevated to operate the jet is impracticable.
It consists, further and more specifically, in means for operating the jet from the source of water under pressure which supplies the tank and in means of communication between the jet service-pipe and the tanksupply service-pipe by which the supply of Water-under pressure is diverted to the jet and shut off from the tank during the flushing action and is cut oif from the jet and returned to the tank when the principal flushing action ceases.
It consists, further, in devices for operating the flushing-valve by means of the supply-pressure and novel means for preventing siphonic action in the supply-pipe which might tend to evacuate the closet-trap when the-water-supply is wholly drawn from a lower point in the service system.
It consists, further, in details of construction which are set forth in the claims.
In the drawings, Figure 1 is a vertical section through a tank and oloset-operating device associated therewith involving my invention, section being made at the line 1 1 on The top of the siphonic discharge-passage appears at B 0 is the water-supply pipe, which affords underpressure for the j et-pipeD and also supplies the tank, being controlled in'the latter by the Valve 0, controlled by the float C in a manner which requires no explanation.
E is the flushing-pipe, connected with the tank by the valve-fixture E, on which the fiushing-valve F seats and with which the overflow and vent pipe G is connected.
H is a fitting having passages which constitote part of the water-supply passage, the pipe 0 being connected to said fitting below the tank, and the continuation of said supply-pipe within the tank (indicated by the letter 0) being connected to said fitting at c within the tank. Said fitting H contains a by-pass chamber H H partitioned by a diaphragm H through which a port H isformed, in which a valve J reciprocates. In line with said valved port the fitting H has an upper open boss H and lower a more elongated boss H and in line with the latter a slight inwardly-protruding boss H which constitutes a seat for the valve J. The jet-supply pipe D is coupled to the lower end of the boss H and a cap K is screwed into the upper end of the boss H. Said cap has a port is, which is closed by a valve L, which seats at the inner side of the port under the cap, havinga stem L extending out through the port, said stem being provided with a head Z, and a spring L being interposed between the head and the cap, tending to hold the valve sea ed upwardly to close the port 7s.
The valve J is adapted to seat, as stated,
upon the boss H and when so seated to cut oft communication from the supply-pipe C to the jet-pipe D, such communication being afforded, but for the seating of the valve, through the passage H of the by-pass chamber below the diaphragm H The valve has a peripheral groove h, which spans the plane of the diaphragm H when the latter is seated on the boss H and affords a communicating passage for the water from the pipe by way of the passage H to the passage H and thence to the upper portion of the supply-pipe and thence past the valve 0 into the tank when said valve is not held closed by the float. Said valve J extends up past the passage H into the boss H but does not fit tightly within the latter, sufficient leakage being permitted around it to admit the pressure into the boss above the valve and under the cap K,
this supply-pressure being experienced overthe area of the entire cross-section of the valve, with a tendency to seat the valve, and over the area which is the difference between said cross-sectional area and that of a circle whose diameter is the outer diameter of the seat H with a tendency to unseat the valve, resulting in the valve being held seated with a pressure which the water can exert over the lastmentioned area.
The flushing-valve F, which is operated in a manner which will be hereinafter explained,
. the boss H is pivotally connected to a lever M, fulcrumed on a bracket-arm H of the fitting H and operating at its end beyond the fulcrum upon the head of the stem of the valve L. When the valve F is lifted from its seat, the opposite end of the lever M is brought into contact with the head of the valve-stem and forces the valve L off its seat. The area for the escape of water through the port it when the valve is oif its seat is considerably greater than the leakage area around the valve J in When, therefore, the valve L is thus unseated, the downward pressure upon the valve J is relieved and reduced to the mere pressure of the water in the tank. The upward pressure upon the valve, however, measured by the excess of the cross-section of the valve where it enters the boss H above the area of a circle whose diameter is the outer diameter of the seat H remains as before and is the excess of the downward pressure of the water in the tank upon the entire area of the valve and causes the valve to open, admitting water to the jet-pipe D, thereby operating the jet and priming the siphon simultaneously with the supply of water to the flushing device. This action continues until the valve F again descends so near its seat as to relieve the valve L from the pressure of the lever M and permit it to become seated and close the port 70. Thereupon immediately the leakage around the valve J admits the water-pressure above the latter and seats the valve as before, cutting off the jet-supply and admitting the supply from the pipe 0 by way of the annular groove h to the upper portion C of the supply-pipe and past the valve 0 into the tank, in which, being now nearly empty, the float C is depressed, so that the valve 0' opens with the water-pressure and admits the supply,clo sing when the tank has become refilled.
In order that the siphon, which is formed by the jet-pipe D, supply-pipe O, and communicating passages in the fitting H, may not operate to evacuate the trap in the bowl to which the jet-pipe leads when the water is withdrawn from the jet-pipe O by opening the faucets below the fixture in question, I provide a by-pass vent-passage H in the fitting H, leading from a point below the valveseat H to a nipple H within the tank, and I provide the fitting E with a similar nipple 6, leading into said fitting below the seat of the valve F, and I connect the nipplese and h by, a piece .of pipe, preferably merely a rubber tube 0, slipped over both ends. Through the passage thus afforded an entering through the overflow-pipe Gis admitted to the jet-pipe D, breaking the siphon, which would otherwise operate to evacuate the trap.
The valve F may be operated by any familiar means. I have shown, however, a novel means for this purpose, which I will now describe. The fitting E has a cylindrical portion E extending through the bottom of the tank, and is clamped to the latter by a lock-nut E Within the cylindrical portion E preferably cast integral with it, is a concentric E and in line with the same the lower end of the cylinder is provided with a protruding boss E and the boss and central cylinder are bored through axially. The flushing-pipe E is connected into the cylinder E laterally, opening into an annular space around the inner cylinder E The valve F has a stem F, which terminates in a piston-head F fitting easily in the bore of the cylinder E and assisting in guiding the valve F, which is, however, fairly guided by the lever M, fulcrunied to the bracket H above described. The stem F may be connected pivotally to the valve F to avoid possibility of cramping, in view of the short movement of the lever F on the long arm of the lever M. The pipe P is connected to the boss E communicating thus with the axial bore of the cylinder E and extends thence to a valve-chamber R, mounted on the slab S at or near the level of the closest-seat. From the supply-pipe O a branch C leads to the same valve-chamber R, the branch O entering below the valve-seat R, while the pipe P leads from the chamber above said valveseat. The valve T, seated thus between the points of communication of the pipes 0 and P, is held normally seated by a spring T, coiled about its stem T which passes out through a suitable stuffing-cap R and provided with a handle T It will be observed that the valve is seated by the spring T against the supply-pressure which enters through the pipe 0". After being pulled off its seat said supply-pressure will operate through the pipe P against the piston F and, the area of said piston being properly calculated, in View of the supply-pressure and the depth of water maintained in the tank, said supply-pressure may Joe ample to lift the valve F oft its seat against the pressure of the tan k-water, which alone tends to hold it on its seat. The operator, opening the valve T by means of the handle T causes the flushing-valve to be opened by the supplypressure and, the opening of the flushingvalve in turn causing the valve L to be opened, causesthe supply-pressure to open the valve J, thus admitting said pressure to the jetpipe. The operator having immediately dropped the valve T as soon as the flushingvalve opened and the piston F being an easy fit and permitting some leakage past it, the valve F can seat again in the usual manner, notwithstanding the presence of waterin the pipe P and under the piston, thus bringing about the action above described, whereby the supply-pressure is cut off from the jet and applied to the tank to refill the same.
