.VALVE FOR WATER-CLOSETS.

SPECIFICATION forming part Of Letters Patent No. 679,368, dated July 30, 1901. Application filed February 9, 1901. Serial No. 46,621. (No model.)

To all whom it may concern.-

Be it known that I, JOHN DENTON, a citizen of the United States, residing in Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Valves for Water-Closets; and I do hereby 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 ap'pertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to flushing apparatus for water-closets and it has reference particularly to the class of such apparatus in whichthe water-supply, which is turned on manually, is cutoff automatically after apredetermined amount of water has been permitted to flow.

My invention is fully illustrated in the accompanying drawings, wherein- Figure 1 is a vertical sectional view of one form of my apparatus, parts thereof being shown in elevation. Fig. 2 is a transverse vertical sectional view on'the line x at in Fig. 1. Fig. 3 is a vertical sectional view of another form of the apparatus, certain modifications being here illustrated. Fig. 4 is a View in end elevation of the apparatus shown in Fig. 3. Fig. 5 is a horizontal sectional view on the line 'y y in Fig. 3. Figs. 6 and 7 are views, respectively, of a detail involved in the two forms of the apparatus already referred to and of another detail involved in the apparatus shown in Figs. 1 and 2. Fig. 8 illustrates a modification of a certain valve construction involved in the two forms of my invention already referred to; and Fig. 9 is a View, partly in elevation and partly in verticalsection,of another form of the apparatus.

In the accompanying drawings,a designates a shell or casing comprising in its construc tion a substantially L-shaped chamber 1), which is formed open at the top, the opening being normally closed by a detachable wall or plate 0, forming a cover.

d designates the inlet or water-supply pipe, and e designates the discharge or flushing pipe. These pipes have communication with each other through a passage-way, which in the apparatus shown in Fig. 1 is in the form of a pipe h, whereas in the apparatus shown in Figs. 3, 8, and 9 said passage-way is in the form of a chamber g. Whatever the form of this passage-way, it preferably constitutes an integral portion of the shell orcasinga, and with the chamber 1) of this casing, and preferably at the lower end thereof, it has communication, as through a port h, which is in Figs. 1, 3, and 8 of tubular form, having its inner end portion arranged vertically in the chamber.

2' designates a valve which controls the flow through pipe d and which is adapted to take against a suitable seat j. This valve is carried at the lowerend of avalve-stem 7a, which projects upwardly through the passage-way and into the upper portion of the chamber b. In that embodiment of my invention which is shown in Fig. 1 said valve-stem extends through one of two tubular parts Z, which connect the upper or overhanging portion of the shell with that portion of the apparatus which constitutes the passage-way. In that embodiment of my invention which is shown in Figs. 3, 8, and 9 said valve-stem extends through the passage-way g, into which the pipes (Z and e lead. The upper end of the valve-stem is provided with a header, having an opening 0, into which projects one end of a lever 19, which is fulcrumed on a standard q in the upper portion of the chamber 5, the other end of said lever being beveled, as at r, and normally pressed downwardly by a weight 8.

i designates a lock-bar which is alined with the lever 19 when the latter is in its normal position and which is arranged to slide horizontally in a suitable supporttt in the chamber and in a recess 0, which is formed in the end wall of the casing and into which the outer end of said lock-bar extends. The innor end of the lockbar is beveled correspond ingly to the bevel of the lever 19, so that when the beveled end of the latter is elevated the two bevels will wipe freely the one on the other, with the result that the lock-bar will move longitudinally. If desired, a roller 10 may be carried either by the lover or the lock-bar to facilitate this action.

at designates a vertically-movable spindle which carries a float y, arranged to move freely in the vertical portion of the chamber b. The float is preferably secured ad justabl y on the spindle by means of a set-screw z. The lower wall of the vertical portion of the chamber 1) is in the form of a plug 1, which is screwed into the casing. In this wall the lower end of the spindle is guided either by being fitted into a vertical recess 2 (said lower end of the spindle and the recess being preferably squared to prevent the spindle from turning) or by providing the plug with a vertical stem 3, which is adapted to extend into the spindle, which latter is in this case made cylindrical, being provided with a vent 4, so that should the hollow spindle become filled with water the action of said spindle will not be clogged. The upper end of the spindle carries a head 5, whose upper extremity is guided in a vertical bore 6, that is formed in the cover c. According to the constructions shown in Figs. 1 and 9 this head is provided with a verticallyoblique cam portion 7, which extends between antifriction-rollers 8, that are vious manner upon the longitudinal move ment of the lock-bar) will descend, causing the lock-bar to project its beveled end under the beveled or weighted end of the lever, thus locking the latter in the elevated position. If desired, the action of the float and spindle in normally tending to force the lock-bar inwardly-2'. 6., toward the leve"r1nay be augmented by a spiral spring 11", interposed between the outer end of said lock-bar and a portion of the wall of the casing a, which,

with the object of facilitating the assembling of the parts, may be in the form of'a cap 12, screwed in place over the end of the recess 0).

here the spindle is of cylindrical form, it is preferably screwed into the head 5, and to facilitate the assembling and separation of i the parts the lower end of the spindle maybe provided with a cross-cut 13 for the reception of the end of a screw-driver.

The valve-stem 7c is adapted to be actuated by a vertically-movable spindle 14, which is guidedin the cover and whose lower end is set into a recess 15, formed in the upper end of the valve-stem, while its upper end is pro vided eitherwith a head 16, adapted to receive a weighted actuating-lever 17 which is fulcrume'd upon the cover a, or with a knob 18. In order tomormally raise the spindle where the same is to be actuated by the knob, I provide a spiral spring 19, which is interposed between a collar 20 on the spindle and the cover and which, if desired, may be in closed in a tubular projection 21 of the cover, such projection having a cap 22, through which the spindle extends.

Since the general operation of the several forms of the apparatus which are set forth herein is substantially the same in all of them, it is appropriate to explain it at this point. Upon the depression of the valve 2' through the medium of its valve-stem and the spindle 14, and the consequent opening of the watersupply or inlet d, the water will rush into the apparatus through the passage-way and out the discharge 6. Said discharge should preferably be smaller in diameter than the inlet, so that a portion of the water will be caused to flow into the vertical portion of the chamberb. However, where there is considerable pressure this is not essential. (See Fig. 9.) As has been already described, upon the opening of the valve and the simultaneous action of the lever 19 the latter is locked in its inclined position, holding the valve open by the lock bart. The parts will remain in this position, therefore, until the float and spindle rise, causing the lock-bar to retract and release the lever. This action of the float and spindle results upon the flow of the water which cannot pass out of the discharge 6 and which tends to fill the chamber 1). Upon the withdrawal of the lock-bar by the action of the rising float and spindle the lever is released and by the action of its weight returned to the initial position, closing the valve. tVhen the valve closes, the water in the chamb'erp flows back out of the-same, draining either out of the discharge-pipe, according to the construction illustrated in Figs. 3, 3, and 9, or out of a special drain-pipe 23, according to the construction shown in Fig. 1.

If desired, the drain may be controlled by a special valve construction. I have shown several forms of this expedient in the drawings. As shown in Fig. 1 it consists of a rubber, leather, or other flexible disk 24, having acentral opening in'which works a cylindrical valve 25, which is closed at both ends and has one or more vertical slots 26. The disk is secured in place between two metal disks 27, having openings of larger diameter than the opening in the disk 24, the three disks being in turn interposed between the ends of the pipe 23 and the nipple 27, projecting from the body of the apparatus, and to which said pipe is secured by a coupling 28. The valve 25 has sufficient. vertical play so that when elevated the slots will be uncovered by the flexible washer, thus closing communication from the apparatus to the pipe. As shown in Fig. 3, where the discharge-pipe is used also as a drain,-a valve 29 of the same construction as the valve 25 works in a flexible disk 30 like the flexible disk 24, which is secured to a nipple 31, projecting from the body of the apparatus, by a bushing 32. As shown in Fig. 8, the duct h, leading from the passage-way, is interrupted by a duct 33,

IIO

which affords communication between the discharge-pipe e and the chamber g. Communication between the two portions of the pipe thus separated by the duct is, however,

' made possible by means of a longitudinallymovable tube 34, which traverses the duct, its ends extending into the adjacent ends of said portions of the pipe. A packing-ring 35 is secured at each of said pipe ends and around the tube by a cap 36, secured to said pipe ends. The tube has a side duct 3'7,which may be closed or opened, according as the tube extends more or less into the portion of the pipe which leads to the chamber Z).

The several valves just described are adapted to be actuated by a vertically-movable spindle 38, which extends up into the upper portion of the chamber 6 and has a head 39, to which one end of a lever 40 is pivotally connected, said lever being fulcrumed in said chamber 5 and having its other end eXtending into another opening 41 in the head of the valve-stem 7r. \Vhere the valve is of the form like the valves 25 and 29, the spindle 38 may be integral therewith. Where the valve is of the construction shown in Fig. 8, the lower end of the spindle is bifurcated, as at 42, being provided with oblique slots 43, receiving pins 44 on the tube.

In view of the foregoing it will be understood that when the valve t' is actuated to permit the inflow of water for the flushing the spindle 38 will be elevated through the medium of the lever 40 and the valve which controls the drain from the chamber 1) closed. The water can thus flow in but two directions-namely, into the chamber 1) and out of the discharge-pipe. Upon the automatic release of the lever-p and return of the valved to its seat the valve controlled by the spindle 38 will open, permitting the drain of the chamber Referring to Fig. 5, it will be seen that in the apparatus shown in Fig. 3 the flow of the water to the discharge-pipe is around the duct h, which spans the opening to said discharge-pipe. If desired, a regulating-valve 45 may be provided to control the amount of flow of water through the duct h.

In order to obviate leakage of the water from the chamber 6 should any of the parts get out of order and the pressure in the chamber I) become abnormal, I provide the spindles 14 and a: each with a seal 46, which is adapted to be held against the cover by a collar 47 on said spindles. If it should also be desired to permit an escape of air which may accumulate in the chamber, a perforated cap 48 may be screwed upon a nipple 49 over the bore 6.

By arranging the float y adjustably on its spindle the same function as that of the regulating-valve 45 is subservednamely, of rendering the action of the parts controllable, so that the flushing may be stopped after a period of any desired duration. 4

The apparatus shown in Figs. 3, 8, and 9 are useful, especially where the bowl is disposed below the apparatus and the flow is consequently down. WVhere the bowl is above the apparatus, and the passage-way cannot therefore drain out of the discharge-pipe, the apparatus illustrated in Fig. 1 is employed, the valve construction serving to close the drain while the apparatus is flushing.

A chamber 50, (see Fig. 1,) between the lower portion of the chamber 1) and the ad jacent tubular part Z, may be used auxiliarly to the chamber b should the latter not be found large enough, communication between the two being afforded by a duct 51.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a flushing apparatus, the combination of a water-supply, a water-discharge having communication with said water-supply, a manually-opened water-supply-controlling means, a suitabIy-fulcrumed lever connected to said water-supply-controlling means and normally pressed in one direction, a rectilineally-movable lock-bar, said lock-bar and the lever having correspondingly-inclined surfaces adapted to wipe the one on the other and said lock-bar being movable into the path of movement of said lever, a chamber also having communication with said watersupply, a float arranged in said chamber, and a spindle carried by said float and having an oblique or cam portion engaging said lockbar, substantially as described.

2. In a flushing apparatus, the combination of a Water-supply, a water-discharge having communication with said water-supply, a water-supply-controlling means, a locking mechanism for said controlling means adapted to maintain the same at the open position, a float structure controlling said locking mechanism, a chamber for said float structure, said chamber having communication with the water-supply, a drain for said cham ber, a valve controlling said drain, a spindle connected to said valve, and a suitably-fulcrumed lever connecting said spindle and said water-supply-controlling means, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 28th day of January, 1901.

JOHN BENTON.
