SPECIFICATION forming part of Letters Patent No. 737,859, dated September 1, 1903;

Application filed March l, 1901. Serial No. 49,527. (No model.)

To all whom t may concern:

Beit known that I, JOHN NELSON, a citizen of the United States of America, residing at Chicago, in the county of Cook, in the State of Illinois, have invented certain new and useful Improvements in Cisterns, of which the following is a specification.

My invention relates to cisterns for waterclosets and the like, but more particularly to the valve mechanism for effectin ga discharge of water from the cistern for the purpose of flushing the bowl; and its Objectis to provide simple, efficient, and reliable valve mechanism of that type known as seat-operated valves in which the valve mechanism is automatically operated by the seat of the watercloset.

In the drawings, Figurel is a section of the cistern, taken on line A B of Fig. '2, the water-closet bowl and connection being shown in elevation; Fig. 2, an elevation of the parts within the cistern, the front side of such cistern being removed;v Fig. 3, a plan view of the cistern; Fig. 4, an elevation of the valve and parts immediately cooperating therewith and showing the catch in set position ready to open the valve as soon as permitted by the seat; and Fig. 5 an elevation of the Valve, showing the same as opened by the catch device and during the period of discharge of Water from the cistern.

The cistern 1, which may be either of the low-down type, as herein shown, lor of the high-up type, has a bottom opening through which extends a nozzle 2, secured therein by the usual couplings, and having at its upper end a valve-seat 3, on which seats the valve 4. This valve preferably has at its periphery a seat proper of rubber or other suitable material. Two arms or standards 5 rise from this nozzle and are connected together at their top by a cross-bar 6, having acentral hole 7 to receive and guide a sleeve or plunger 8. The valve has a stem 9, received by the bore of the sleeve, and thereby also guided, and, further, has a truncated conical portion or enlargement 10, forming a shoulder 11 for the catch. As shown, this enlargement and stem are preferably integral with thel valve-body itself. The valve-stem is preferably flattened on one or more sides to permit the air Within the sleeve to escape when such sleeve is deL pressed.

The catch mechanism herein illustrated is an example of what may be employed for the purpose desired, and the same comprises a ring l2, having a screw-threaded socket-piece 13 at one side to receive the stem 14 of a ballfloat 15, which is normally submerged. At the side opposite the socket-piece the ring has a hook 16, pivoted at the end of lateral lugs 17 at the lower end of the sleeve and having a curved lower end 1S, adapted to engage the shoulder- 1l under certain conditions, as hereinafter set forth. The valve may have a depending stem guided by a suitable guide 19, arranged in the nozzle. (See Fig. rl.)

V To operate the valve mechanism and the catch by means of the seat of the water-closet, the following instrumentalities may be employed as being suitable aud preferable for this purpose: A rod 2O is screwed into or othwise secured to the sleeve 8 and is pivotally connected at its upper end to the end of a lever 21, which is pivoted to a fulcrum-rod 22. The other end of this lever has pivotally connected to it the lower end of a vertical rod 23, whose upper end isin connection with a vertical operating-rod 24. This rod 24 works in a barrel 25 or cylinder, which extends through the bottom of the cistern and contains a spiral spring 26, bearing against an adjusting-nut 27, screwing on the lower end of such rod 24. A cap or thimble 28 screws on the end of the rod 24 and receives the thrust of the seat mechanism, as hereinafter described. The barrel or cylinder 25 also forms a support for the fulcrurn-rod 22, which is attached thereto by a collar 29.

The nozzle 2 from the cistern connects with the water-discharge pipe 30, communicating with any suitable bowl 31 of a water-closet and having a seat 32 normally held in slightlyraised position, as shown in Fig. 1, by means of the downward pressure of the rod 24 on the end of a lever 33, secured to the seat and extending beyond the pi vot thereof. cock 34 and the after-fill pipe 35, emptying into the overiiow-pipe 36, being so well known do not require any detailed description.

Assuming that the cistern is filled with water to the normal level and the parts are in IOO their normal position, as shown in Fig. 2, the operation is as follows: When the seat is depressed by occupation thereof, the rod 24 is forced upward against the tension of its spring by reason of the upward thrust of the seatlever, and the movement is communicated through the rods and levers described, so that the sleeve 8 will be depressed, such sleeve sliding upon the stem 9. The pivotal point of the catch device will consequently be depressed or carried downward, and when the sleeve is depressed to its limit the hooked end 1S will engage under the shoulder 11, inasmuch as the buoyant effect of the small `float 15 is to bring such end toward the central axis of the valve. The catch remains thus in engagement with the valve so long as the sleeve is in depressed position-that is, so long as the seat is occupied. When, however, the seat is now vacated, the tension of the spring 26 will restore the parts to normal position, thereby raising the sleeve and also opening the valve, because such valve and sleeve are connected together by the catch. The cistern will now be drained of water for flushing the bowl, and the discharge-valve will remain in its raised or open position until vthe Water in the cistern has so far receded as to carry the small oat 15 downward with it, thereby releasing the hook or catch from t-he shoulder 11 and permitting the valve to close by gravity. The tank will thereupon be filled with water by the ball-cock in the usual inanner, and the cistern will be ready for the next operation.

It is evident from the foregoing description that the catch mechanism is set or put into engagement with the valve at the moment when the seat is occupied and that the restoration of the parts to normal position when the seat is vacated causes the catch mechanism to elevate and open the valve, which is thereafter released and permitted to close at the proper time-that is, when the water has been substantially drained from the cistern. WhileIhave herein shown my invention as applied to a cistern of the low-down type, yet it is obvious that` the same is applicable to the high-up or overhead type, the only changes being the lengthening of the discharge-pipe 30 and of the rod 24, rendered necessary by the elevation of the valve mechanism. Furthermore, while I prefer to use a spring for the purpose of applying tension on the rod 24, yet it is evident that its equivalent, a weight, might be substituted. The spring, however, is preferred, particularly because ot' compactness and capability of adjustment in tension.

The construction and operation of my device is such that in case the weight of the 0ccupant is momentarily withdrawn, either purposely or accidentally, so as to open the valve, apartialflushwill occur,inasmuch asthe valve after being thus opened will be closed again immediately upon the reoccupation of the seat. It is apparent, therefore, that when the valve is opened it will stay open and drain the cistern only in case the bowl-seat remains in its normal partially-raised position, and that consequently the valve is to this extent controlled by the occupant.

I claim- 1. In a tank or cistern forwater-closets and the like, the combination, with the tank, of a discharge-Valve therein, a vertically-movable and normally upwardly pressed catch arranged in the tank and when depressed adapted to engage the valve while closed but not to open the sameat that time, seat-controlled mechanism cooperating with said catch to depress it when the seat is occupied and to permit the catch to rise and the engaged valve to open when the seat becomes unoccupied, a s-ubmergible float at all times connected with said catch and arranged to positively move the same laterally of the Valve, both into and out of engagement with such valve, and suitable water-supply mechanism separate and independent, both in structure and operation, from said float.
