.ence being had therein to the-accompanying g drawing. a i

This invention relates to water closet fl'ushing systems, and has specially in view a 3 novel type of flushing tank and co perating I automatically acting valves which control the delivery ofwater therefrom,-:the arrange inent "of the valves and their connection being such that the flushing of the closet bowl .is accomplished by the weight of the person using the same. 7 a

Referring to the accompanying drawings, 2 1 designates 'a conventional representation of a flushing tank which has the usual, or any preferred type of float valveconnnunication with a source of watersupply. baid tank is divided horizontally by means of a diaphragm'2 to form an upperc'hamber :or compartment 3 in which the float valve communication with the source of watersupply is mounted, and a lower com artment 4. An opening 5 formed in the diaphragm 2 is provided with a valve seat- 6, said opening forming the communication between the upper chamber 3 and the lower chamber 41- :and? is controlled by means ofa valve 7 having a stem 7 a which projects through and is 5 guided by a gland extension 8 carried by the 1 valve seat 6. I The lower chamber or room- 3 partment-C. has an 'op'enin'gt) ,formed through its bottom which receives a bushing 10 prov-ided with exterior threadsll which are on E Specification of Letters Patent.

! an interiorly threaded end 12 of a valve chamber 13 having a valve seat 1-1. 'ztorm'ed in its upper portion. The stem 7 oif the valve 57 extends through the lower chamber 4 and into and below the valve seat 14in the valve chamber 13 and carries a valve p A short pipe section 16 has its upper end i held in engagement with the bottom of the valve chamber 13 by means of a detachable coupling '17, said pipe having its lower end nested within another pipe section 18 the lower end of which is provided with a longitudinal slot 1 9 and held within an enlarged coupling head 20 of the pipe 21 that delivers the flushing water to the closet bowl. The

coupling head 20 is of considerably larger diameter than the pipe section 18, and at one side has a bulged out portion 22 which is open to the atmosphere.

The stem or rod 7 a is fast within the valve 15 and projects beyond the same, and its projected end carri'esn threadedcoupling 23 which holds in engagement therewith a valve 3 operating rod 24 that extends through the two pipe sections 17 and 18 and has its lower end portion upturned as indicated at 2'5, and projected through the slotted end of the pipe section 18 and up through the bulged portion-of the coupling head 20. The end of the upturned portion 25 is threaded for the reception of-a lock nut 26 which re tainsian eye 27 thereon'from which projects a vertically arranged pivot ear 28 which has a pivotal connection with a vertically arranged *rod 29 the lower end of which carries a pivot ear for pivotal connection one to end of a rocker arm '30. Said rocker arm 30 has its outer portion bifurcated to form two spaced apart strap members 3132 which have pivot openings 33 formed through them for engagement with a hinge connection '34- carried {by the water closet seat framing The ends of said strap members 31 and 32 carry ears 36 which receive pintles 37 of hinge members 38 carried bythe watercloset'seat 39. The seat cover 40 has "the usual hinge connection 41 with the dlosetlseat 39.

In Fig. 1 of the accompanying drawings the closet :seat and valve connection with thesource of water supply is shown in the positions they assume when the closet is not in use. In this position the weight of the water in the upper compartment 3 of thereby depressing the rod 24, moving the valve 15 from its seat 14, and causing the rocker arm to hold the closet seat raised from its framing. It will be seen that when the seat is occupied, the rocker arm exerts an upward pressure on the rod 24 sufficient to push the valve 15 to its seat 14, and through the connection between said valve 15 and the valve 7 raise the latter valve from its seat and thereby permit the water from the upper compartment to escape into the lower compartment 4 and the valve chamber 13 filling the same, but be retained therein owing to the valve chamber being closed through the seating of the valve 15. WVhe-n the weight is removed from the seat, the pressure of the incoming water in the upper compartment 3 will force the valve 7 to its seat, thereby cutting ofi the supply of water to the lower compartment 4, and remove the valve 15 from its seat 14, to allow the water that has accumulated in the said compartment 4 and valve chamber 13 to flow into and flush the closet bowl;

Any suitable means may be employedfor supplying the necessary air to the lower compartment 4 of the flushing tank, one convenient form being illustrated in the drawings wherein an upstanding pipe 42 carried by the diaphragm 2 communicates with the air above the upper compartment 3 and delivers the air through an opening 43 to said lower compartment.

In addition to the automatically acting features of the valves, it will be seen that the present system is one that is so arranged that the various connections thereof may be readily disconnected to permit of the operating mechanism being readily inspected or repaired, or replaced, should the same be necessary or desirable. For instance the valve chamber 13 may be readily disconnected from the bushing carried by the tank; the pipe section 16, through its coupling connection 17 may be readily disconnected from the valve chamber to permit inspection or repair of the valve 7 or the coupling be- 7 tween the valvestem and the rod 24; and

the connections between the pipes may be readily disconnected. Also, the connections between the rocker arm and the seat, and

the connections between the valve operating rod 24 and said rocker arm, is one that may be readily disconnected. Claims 1.
