WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 558,130, dated April 14, 1896.

Application filed January 30, 1893 To aZl whom it may concern.-

Be it known that I, DAVID STEELE WAL- LACE, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Water- Olosets; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in water-closets, and especially to that class known as double-trap siphon-closets.

The objects of my invention are, first, to provide a closet having the fiushing-reservoir secured directly to the top of the closet or cast integral with it 5 second, to provide a closet which is retrapped directly from the city pressure, and consequently does not require a portion of reservoir contents at each flushing to retrap the bowl; third, to provide a closet adapted to receive the entire contents of the reservoir at each flushing; fourth, to provide a siphon-closet with deep traps; fifth, to provide a perfectly-noiseless closet and reservoir; sixth, to provide means to automatically regulate the fiushing-valve to retrap the closet from the city Water-supply; seventh, to provide a double-trap noiseless closet with an independent air-passage to the top of the reservoir; eighth, to provide a noiseless flushing-rim and reservoir attached directly to one another or cast integral, which can be at tached to or cast on any make or design of bowl or arrangement of trap or traps at present in use. I attain these objects by the mechanism illustrated and described in the accompanying drawings and specification, in which Figure 1 represents a sectional elevation through the broken plane A of Fig. 3.

of the reservoir and shows in dotted lines the arrangement of the discharge-passage of the second trap. Fig. 5 represents the seat of the flushing-valve. Fig. 6 represents a perspective view of the reservoir and closet cast integral.

Similar letters and figures of reference refer to similar parts throughout the several views.

Referring to Fig. 1, B designates the bowl of the closet. Its rim 0 is enlarged in the form of an oval. It has a water-passage 0 formed in it, which is continuous around it. It is also open all around at its inner under side at E, as shown. The Water-passage extends backward into the body of the closet and registers with an aperture E in the bot- This passage is con trolled by a valve G and its seat G. The bowl B discharges into the discharge-passage II, which is arranged to extend backward from the front of the closet and upward to near the top of the closet. It is also diverged to one side of the longitudinal center of the closet. It then curves downward to the base of the closet and then turns across the center and upward, forming a second trap, the bowl and the first part II of the dischargepassage to its highest point forming the first trap.

I carry the first run of the discharge-passage as high as possible and the downward passage as far down as possible in the closet in order to get deep traps, and also a large volume of water in the bowl and, in addition, a long siphon-leg H. The second upward turn I of the discharge is carried up to get as deep a trap as possible and have its highest point below the lowest point of the first trap. It then extends toward the front of the closet and opens out at the bottom of it at I, where the closet is flanged to, connect to the soilpipe. I provide the second trap with a ventoutlet 1*, by which this trap may be vented. J is an air-passage formed in the top of the closet from the top of the first trap to the pipe K, which is secured to the reservoir and closet. It is provided with a perforation K, which is arranged to register with the air-passage and continue it to the top of the reservoir F, or above the water-level. I arrange this airpipe in reservoirs which are secured to the closets so that I can use it to take the place of a bolt to secure the two together, as illustrated in most of the figures. To accomplish this, I thread the lower end, which is closed by a plug or other means, and provide it with nuts L, arranging them to clamp the two together, as shown.

WVhen the reservoir is separated from the closet, it is constructed of wood or other suitable material and lined with metal and must be secured by bolts or other means to the closet; but when made of porcelain it is cast integral with it. The reservoir, when separate, sits directly on the closet,which is formed to project laterally on each side of its longitudinal center to make a base for it. Awatertight joint is made between the two by inserting a gasket M. I secure the reservoir to the closet preferably by the air-pipe K and also by the water-inlet pipe N, which is threaded and provided with nuts similar to the air-pipe or valve-seat G, which has a third nut between the two. These two pipes are arranged at one end. At the opposite end, in place of using bolts, I preferably form the valve-seat with two depending rods 0 and O, which extend through the closet. The ends of these rods are threaded and provided with nuts which are adapted to secure the closet and reservoir together. The body of the valveseat is threaded and provided with nuts M by which it is secured to the bottom of the reservoir.

The fl ushing-valve proper and seat, with the exception of the depending threaded rods, are old; but in order that I may noiselessly flush the closet and use in so doing the entire contents of the reservoir and retrap the closet from the city pressure or other source of supply it is necessary to automatically control it, so that it will remain open a short period of time after the closet has been flushed, and also so that it will close itself quickly and easily without that swash or wire-drawing noise being made by the water so common, as the valve closes, in most closets. I preferably carry out this feature of my invention in the following manner: To the top of the valve I attach a weight P. To the valve-stem I pivot a lever Q loose enough to allow the valve always to seat squarely. I pivot the lever on a shaft R, which I secure in any convenient manner in the reservoir. I illustrate it secured by pins in a U-slotted clip R, which is soldered to the metal lining of the reservoir. In porcelain reservoirs this shaft would have to pass through its sides and be secured against leakage by suitable nuts and washers. To the opposite end of the lever I pivot a box X, which may be a water-containing receptaole of any suitable form. In the bottom of the box are made two perforations T and T.

T is the water-inlet into the box, and it is made larger than T, which is the outlet. The inlet is controlled by a common clapper-valve U, which operates to admit the water into the box through the perforation and retain it.

T is a small perforation which is adjustably controlled by a plate V, which is movably secured laterally over it by a screw V. A perforation V is made through the plate to register with T. ally over the lower perforation I am enabled to partially close it, and thus regulate the time required to empty the box. As soon as the box is empty the flushing-valve is closed by the weight. To the top of the box I secure a manually-operating push-rod 8, which is shown in Figs. 1 and 6. It extends up through the cover F of the reservoir.

X designates the overflow pipe. It is threaded to an opening in the valve-seat and communicates with the flushing-passage. It is also open to the atmosphere through the rim 0 when the closet is not flushing. N is the water-supply pipe, and N its valve, which is controlled as those in common use by the float N The top outlet of the air-pipe K is provided with a valve Y, which is pivoted to a lever Z, pivotally supported in a bracket 1, which is secured to the pipe. A depending rod 2 is pivoted to the opposite end of this lever and supports at its lower end a float 3, which operates to hold the valve open when the reservoir is full or is being filled with water. The rod 2 is also supported by a bracket 4, attached to the pipe.

5 designates a casing, preferably a metal casing or box. It is adapted to fit over the air-pipe and also the overflow-pipe, although it is not necessary that the overflow-pipe be placed under it, as I could vent the top of the casing by other means. The casing is airtight. It extends preferably to and rests on the bottom of the reservoir. One side, at 6, is cut awaya short space above the floor at a predetermined point in proximity to the float 3 to allow the water to enter it freely and to exclude outside air from it until the water is below the said opening.

The operation is as follows: The water supply enters through the pipe N. The weight on the flushing-valve is SllfllClGlll] to keep it closed when the box X is empty or nearly so. As the reservoir fills with water it flows into the box through both of the perforations in its bottom, the larger one allowing it to fill as quickly as the reservoir. Normally the box is not full of water, the line '7 designating approximately its highest point in the reservoir and box. To flush the closet, press down the rod 8, which pushes the box under water, filling it full, and thereby opening the valve, allowing the water to rush through the spider which supports its guidestem into the flushing discharge-passage and closet-rim. The box being now full of water is heavier than the valve and holds it open. The

water in the reservoir quickly runs out; but the water in the box runs out slowly through the small outlet T, which allows the water from the city pressure to flow into the reser voir, as its float has dropped and opened the valve with the discharge of the water. This By moving the plate later-- water passes through the valve and retraps the closet, and the small opening int-he box is gaged so as to hold the flushing-valve open until sufficient water has passed through it to retrap the closet. By this time the box is empty and the weight closes the flushing-valve, lift in g the box again to its normal position. The air in the discharge-passage 11 between the traps is removed and a siphon established by the outflowing water in the reservoir at the commencement of flushing, which creates a suction in the casing 5, that draws the air between the traps through the air passage and pipe, the valve being held open by the float 3, thereby creating a vacuum between the traps, creating a siphon in the discharge-passages H and H, which empties the closet. The overflow-pipe is closed to the atmosphere the instant flushing commences by the water passing through thedischarge-valve and closing its outlet. As the reservoir refills the float 3 opens the air-valve Y and the air in the casing 5, which is compressed by the rising waters, finds an outlet through the overflow-pipe. The water flows from the reservoir through the passage around the rim 0 and disseminates evenly over the surface of the bowl through its annular. opening E, thus flushing its entire surface.

I preferably make the bowl deep, as the large body of water it holds g' es a more thorough flushing and a longer and better siphon than is usual, while the placing of the reservoir directly on the closet, or casting it as an integral part of it, obviates the use of pipes, and also makes the flushing noiseless. The oval hollowrim and top part of the closet containing the air-passage and air-pipe, the reservoir, the box, an d water column for automatically closing the flushing-valve and regulating it so that the closet can be retrapped by the water-pressure can be applied to any arrangement or system of traps in water-closets at present in use. The holes 9 are used to secure a seat to the closet.
