FLUSHING APPARATUS.

SPECIFICATION forming part of Letters Patent N 0. 417,125, dated December 10, 1889.

Application filed April 1, 1889- To aZZ whom it may concern:

Be it known that I, RICHARD \VALsH, a citizen of the United States, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new and useful Improvements in Flushing Apparatus for Water-Closets, of which the following is a specification, reference being had therein to the accompanying drawin This invention relates to new and useful improvements in flu shin g apparatus for waterclosets; and the invention consists in the peculiar construction, arrangement, and combinations of parts hereinafter more fully described, shown in the drawings, and then definitely pointed out in the claims.

Figure 1 is a sectional elevation of a watercloset provided with my improvement. Fig. 2 is a plan. Fig. 3 is a vertical central section of the flushing-valve, and Fig. l is a horizontal section of the flushing-valve.

A is a bowl.

B is a hinged seat.

C is a hinged frame underneath the seat.

D are vertical pushbars secured to the hinged frame and projecting through the stationary seat of the frame against the under side of the hinged seat, whereby they are adapted to hold the latterin a partially-raised position.

E is a flushing-valve, divided by an interior partition F into an induction-chamber G and eduction-chamber H.

I and J are the induction and cduction ports of the valve in axial line with each other, the port I being formed in the interior partition F, and the port .l in the outer wall between the connection K of the service-pipe and the valve-chamber G. The valve-chamber G communicates through the connection K with the service-pipe L, attached thereto, and through the connection M with the Hushing pipe N, which extends up vertically into the flushingtank O and terminates therein into a siphon P. The valvech'amber H is provided with a suitable connection Q, by means of which the valve is attached to the nipple R of the bowl, and with a connection S, to which the flushing-pipe T is secured, which extends upwardly into the fiushing-tanlc O and terminates into a short siphon U.

V is the valve-stem of the flushing-valve Serial No. 305,594. (No model.)

projecting through a nipple W on the valvecasing. This nipple is interiorly provided with a packing around the valve-stem and ex- I underneath the hinged frame 0. The valvestem is provided with a valve-disk Z, which controls the port I, and with a valve-disk Z, which controls the port J, the latter valvedisk being preferably made of elastic rubber to be seated tightly When closed.

The flushing-valve,besides being supported byits connection with the nipple of the bowl, is supported upon the leg A, which adjustably engages into a foot A, secured upon the floor.

It will be observed that by my peculiar arrangement of the valve, whereby the siphonoverflow passes from the tank through the fiushingwalve, only a single double-acting valve is required, instead of two separate valves, as has been proposed, and the valve mechanism is therefore much simplified.

In practice, the parts constructed and arranged as shown and described, are intended to operate as follows: hen the seat is notoccupied, the weight Y causes the lever Y to lift the hinged frame, whereby the push-bars D hold the seat in an uplifted position, as shown in Fig. 1, suitable nuts or collars D being secured upon the push-bars as stops. In this position of the lever the stem V of the valve is fully pushed into the valve and closes the port J, which connects it with the supply and opens the port 1. Upon the seat being occupied the push-bars are depressed and cause the levers to turn the valvestem, which latter is simultaneously withdrawn by the screw-thread engagement of the nut \V on the nipple WV. This movement is sufficient to close the port I and open the port J. Thus water is admitted into the chamber G of the valve, and from there, by the pressure of the water, it is carried up through the flushing-pipe N and siphon P into the tank 0, filling the latter. Now, as the water raises in the tank above its ordinary height it will begin to overflow through the siphon U into the pipe, and from there through the pipe H in the valve into the bowl. This overflow starts the siphon, and a copious rush of water, orso-called fore-flush, will take place through the pipe T into the bowl until the level of the water sinks to the level of the siphon U. The siphon U preferably extends only a little distance toward the bottom of the tank, but enough, provided the tank is sufficiently large, to form a sufficiently-copious overflow or flush to wet the interior of the bowl, and as water flows into the tank right along, if the seat is occupied long enough, a periodical fore-flush or overflow will take place from time to time. Upon leaving the seat the weight Y is caused to actuate the valve-stem to close the port J and open the port I.- This shuts ott the pressure of the Water and at the same time opens communication from the flushing-pipe N, through the port I, chamber II, and connection Q, into the bowl, allowing the water in the flushing-pipe to escape into the bowl and thereby start the siphon I thus producing the ordinary after-flush.

It is obvious that the amount of fore-flush should be limited to retain enough water in the tank to produce at any moment a sufficient afterwash, and to this end the siphon U extends only a little distance below the highest level of the Water in the tank.

WVhat I claim as my invention is 1. In a flushing apparatus, the combination, -wltl1 the bowl, of the flushing-valve provided with the interior partition F, forming an induction and educt-ion chamber in the valve, the service-pipe connected to the induction-chamber through a port J, the port I between the eduction and induction chambers of the valve, the valve-stem provided with the disks Z and Z, automatically controlling the ports I and J by intermediate connection with the hinged seat, the flushing-pipe N, connecting the tank with the induction-chamber of the valve, the overflowpipe T, connecting the tank with the eduction-chamber of the valve, and the siphon U on the said pipe, all combined to operate substantially as described.

2. In a flushingapparatus, the combination, with the flushing-tank and flushingvalve, of the flushing-pipe N, connecting the Valve-chamber with the tank and having a siphon P within the tank, the pipe T, connecting the valve-chamber with the tank, and the short-leg siphon U on said pipe within the tank, substantially as and for the purpose specified.

3. In a flushing apparatus, the comblnation, with the flushing-tank and flushingvalve, of the flushing-pipe N, connecting the valve-chamber With the tank and having a siphon P within the tank, the pipe T, connecting the valve-chamber with the tank, and the siphon U on said pipe within the tank and extending but slightly below the highest level of the water in the tank, substantially as and for the purpose specified.

In testimony whereof I atfiX my signature, in presence of two witnesses, this 6th day of February, 1889.

RICHARD WALSH.
