WATER-SUPPLYING APPARATUS FOR WATER-CLOSETS.

SPECIFICATION formingpart of Letters Patent No. 449,768, dated April 7, 1891.

l Application filed December 29, 1888. Serial No. 294,939. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM H. WARD, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Water-Supply Apparatus for Tater-Closets, of which the following is a specification.

This invention has for its object to provide simple and effective means for operating the outlet-valve of a water-closet supply-tank, so as to give a limited'preliminary wash when thecloset-seat is depressed and a longer second wash when the seat is released.

The invention consists in the improvements which I will now proceed to describe and claim.

' In the accompanying drawings, forming a part of this specification, Figure 1 represents a side view of a water-closet supply-tank having my improvements. Fig. 2 represents a section on line a: 00, Fig. 1, looking toward the left Fig. 3 represents a modification.

The. same letters of reference indicate the same parts in all the figures.

In the drawings, or represents a supply-tank having a supply-cock b and an outlet-valve c, said cock and valve being of any suitable construction. The supply-cock is provided with a lever d, pivoted at one end to the casing of the cock, and having at its free end a float d, WhlGh is supported by the water in the tank. The inner end of the lever is provided with an arm which bears on a valve within the cockcasing, and closes the valve when the water in the tank raises the fioat to a predetermined height. lVhen the water falls, the valve opens and admits more water, as usual. The stem e of the valve has a rod e, which mav be a continuation of the stem, but is here shown as connected thereto by a link f. Said rod passes through a vertical sleeve or guide g, affixed to the top of the tank, and has an enlargement or collar it above said sleeve.

1' represents a weighted operatlng-lever p1v oted at 3' to an ear or bracket affixed to the top of the tank, and having a welght t attached to its longer arm and a pivoted toe piece or latch j on its shorter arm, said toepiece being adapted to yield upwardly, but

being rigidly seated on the lever against downward pressure. The operating-lever has an arm 2', which is connected by a rod on with one arm of a bell-crank lever n, which is pivoted at n to an ear on the tank, and has its other arm connected by a rod, chain, or other suitable means with the vertically-movable seat of a water-closet.

The described connection between the closet-seat and the operating-lever has in itself no novelty,and as the operation of a vertically-movable seat on a valve-operating weightedlever in substantially the manner here indicated is well understood, I do not deem it necessary to show the seat and the means whereby it is connected to the lever 01.

0 represents a short lever pivoted at p to a fixed standard q, and having one end in position to act, as hereinafter explained, on the valve-rod collar h, and the other end in position to be acted on by an arm or projection r, formed on or afilxed to the operating-lever.

8 represents a bent leverv pivoted at t to a standard a, affixed to the tank a, and having a projection or detent s, which passes through and is guided by a slot in the standard it and a weight 8', which normallyholds said detent in position to engage the valve-rod collar 71 when the latter is raised by the'operating-lever, as hereinafter described. On the detent-lever s is formed an arm 1;, the outer end of which supports a rod 10, which extends downwardly into the tank, and is provided with a loop or slot to at its lowerend, through which the float-lever (Z extends. Said rod is vertically adjustable by means of a nut 10', screwed on its threaded upper end and hearing on the arm c.

Operation: When the closet seat is depressed by the weight of the occupant, the operating-lever z is turned by the movement of the seat imparted through the described connection, the end of the lever having the stud 0* being thus depressed. The stud in its downward movement bears on the pivoted lever 0 and raises the end thereof, which bears on the valve-rod collar h, thus causing said lever to raise the valve and give the preliminary wash, the pivoted toe piece or latch j of the lever '5 being moved below the collar 71 by the same movement. The lever o is raised out of contact with the collar h after the latch j has moved below the latter, and the valve then drops to its seat, the latch j remaining below the collar, as shown in dotted lines in Fig. 1. \Vhen the occupant of the closet-seat rises and releases the seat, the weighted end of the lever i (now raised) falls by gravitation, thus raising the latch-piece j on its opposite end and causing the latter by its abovedescribed engagement with the collar 7b to raise the valve, and thus give the second wash, the collar 7L being raised at this time high enough to be engaged by the detent s on the weighted lever s, as shown in dotted lines in Fig. 2. Said detent keeps the valve raised and prolongs the second wash until the water in the tank falls sufficiently to bring the float-lever (1 against the lowerend of the slot 10' in the connecting-rod to, after which the lever s is moved by the continued descent of the float-lever, and the detent is thereby withdrawn from under the valve 71 whereupon the valve drops to its seat and closes the outlet, after which the water admitted through the supply-cock, which was opened by the descent of the float-lever, raises said float-lever and allows the weighted detent-lever s to resume its normal position, restoring the d etent to position to engage the collar 7L when next the valve is lifted by the latch This mechanism is simple in construction and effective in its operation and is not liable to get out of order.

A modification is shown in Fig. 3, in which I substitute for the preliminary wash-lever 0 v a lever 2, located below the top of the tank,

and is pivoted at 3 to a fixed arm extending downwardly into the tank. One end of the leveri is forked, its branches projecting under a collar 7i on the valve-stem e. To the other end of the lever 2 is pivoted at at a weighted latch 5, which is held by its weight against a shoulder or stop on the lever 2, so that it cannot tip independently under pressure exerted in the direction indicated by the arrowin Fig. 3, but yields or tips independently under pressure in the opposite direction. The operating-lever i is provided with a down wardlyprojecting arm 6, which, when the operatinglever is moved by the depression of the closetseat, pressesagainst theweighted latch 5 in the direction indicated by the arrow, and thereby causes said latch to raise the forked end of the lever 2, and thus raise the valve for the preliminary wash. The arm 6 passes beyond and releases the latch 5 and lever 2 after the toe-piccej of the. operating-lever has passed below the collar 7L on the operating-rod 0, so that the said toepiece is in position to raise the valve, as above described, for the second wash. \Vhen the operating-lever i is resuming its normal position after the release of the closet-seat, the arm (5 on said lever moves back over the latch 5, the latter yielding until the arm 6 passes beyond it, and then resuming its operative position. The operation of the apparatus as a whole when this modification is used is precisely the same as above described, the lever 2 performing the same functions as the lever 0, first described.

For the sake of convenience in the wording of the claims, the movement of the operating-lever by the depression of the closetseat is termed the preliminary movement, while the movement of said lever which follows the release of the seat is termed the final movement.

I claim- 1. In a water-closet supply-tank, the combination, with the outlet-valve and the supply cock float-lever, of the weighted operatinglever having an arm or projection, a connection through which said lever is given a preliminary movement and a final movement, as described, a collar connected with the valve, a pivoted latch on said lever, which is placed in operative relation with the valve-collar by the preliminar movement of the operating-lever, and thereby adapted to raise the valve during the final movement of said lever, a valve-lifting lever fulcrumed on a fixed standard and acted on by said arm or projection of the operating-lever, whereby the valve is first raised and then released during the preliminary movement of the operating-lever, a detent-lcvcr fulerumcd at one end adjacent to said former levers and having a weight at its other end, and designed to engage the valve-collar when the latter is raised by the final movement of the operating-lever and connected between said detent-lever and the float-lever, whereby the detent is displaced and caused to release the valve by the depression of the float, as set forth.
