MM i2? c. WBRQWN 85924 CLOSET FLUSHING DEVICE Filed cm. l2. 192e 2 sheets-sheet 1 Patented May 12, 1931 UNTED STATES recarsi CLQSET FLUSI-IING DEVICE Application led October 12, 1929.

rIhis invention relates to iushing devices for closets and has particular relation to those closetsv which have a di'erential control for the flushing water.

In cities where the shortage of water is liable to be acute, surveys have revealed the fact that the greatest amount of water is usedy for iushing of closets. It has alsoV been determined that much water could be saved if the closets were all provided with means whereby a greater or lesser amount could readily be admitted to the closet bowl, depending` upon the purpose tor which the i flushing was desired.

The primary object of this invention is the provision of an improved closet iushing device having a differential control for the flushing water.

Another object of the invention is the pro- '2'0 vision of an improved closet flushing device having two valves of the standard type and so placed as to normally maintain the same static pressure.

Another object of the invention is the provision of an improved closet flushing means having separate spaces to deliver water to the respective valves.

Other and further objects of the invention will be apparent to one skilled in the art from a reading of the complete specification and claims.

Referring to` the drawings wherein I have illustrated my invention,

Figure 1 is a front cross sectional view of one form of my invention.

Figure 2 is a front view of a modified form.

In Figure 1, 10 designates the wall of the tank which contains two water spaces .11 and 12. y A

The wall 10 is of a tank of the low-down type. It is also adapted, of course, to other types.

The water space 11 is of a relatively large capacity and is used to deliver a relatively large amount of water for flushing purposes when a complete flushing is desired. The water space 12 is' relatively small and is intended to deliver a relatively smaller amount of water when a smaller amount is needed.

Serial No. 399,350.

The water spaces 11 and 12 are separated by a partition 18 having an opening 14 lat a height not too great for the water to reach when the water space 11 is filled in a manner to be described. l

At the left in Figure 1 is the intake or inlet control device which I have designated 15. I/Vithin this control device 15 is a suitable valvewhich may be of any well known or suitable type to be found on the market. A

tube 16 supplies water from thewater supply as thevalve within the control device permits. This water passes out from the tube 17 into the water space 11. As the water level rises, in the water space 11, to a point where itwill pass through the opening 14, the water space 12 is also filled with. water.

To prevent overiow of the tank, the inlet valve within the control device 15 is connected L Y to a lever 18 fulcrumed at 19 and connected at its moving end by a link 2O which is in lturn connected to a lever 21 `iulcrumed at 22. On the end of this lever 21 is a fica-t ball 23 `which rises as the level of the water rises. The relative positions of the float-ball 23 and valve are such that the iioat-ball 23 will not close the valve untilboth water spaces are full.

As the water iiows into the water space 11.-, a small stream passes through the pipe 24 and is emptied inte the safety overflow pipe 25 to refill thebowl to bring the water to the proper normal level. f

h-e overtlow'pipe 25 has a passage which leads into the bowl directly, whereby if for any reason, the inlet valve fails to operate, thel tank cannot overiiow. As has already been stated, the pipe 24 reiillsthe bowl, the

water passing down the upright pipe 25,

through the lu-connection 26 and into the pipe 27 which connects to the closet bowl.y p

At the ltop of the pip-e 27 and -opening into it is a valve opening which is normaliy ciosed by the bulb valve 28. T his bulb valve 28 is provided with a stem 29 which is held lin upright posit-ion by a guide 30 supported from a support 31, at the upper end of the stem 29 is a loop 32 and therebelow is a sliding lifting member 33. The lifting member e 33 is provided with an eye 83 which surrounds the stem 29 and engages the loop 32 during the lifting operation. The lifting member 33 is pivoted at its upper end to a lever 34 which is fulcrumed at 35. The lever 31 has an operating handle 36 by which the bulb valve 28 is lifted to start the flushing operation.

In the smaller water space 12 are located elements similar to those just described. An outlet L-connection 126 with a valve opening is connected with a passage to a pipe 127 which leads to a pipe 27 which, as already stated, leads to the bowl.

The bulb valve 128 is normally seated on the valve seat and is provided with a stem 129. A guide 130 is supported by a support 131 from the overflow pipe 125. A lifting device 133 is constructed similar to the lifting device 32, already described and engages the loop 132 on the end of the stem 129, when the lifting devicel is lifted. The lever 134, fulcrum 135 and handle 136 are respectively similar to the

corresponding parts

341, 35, 36, already described.

In operation, the water space 11 iills` first, the water then overflowing through the opening 14 into the smaller water space 12. IVhen the smaller water space 12 is filled, the ball 23 will shut off the intake supply and the two water spaces will remain full. It is to be noted that from this condition with the valves 28 and 128 having the same static water pressure and'being connected to the two water spaces, respectively any one of three results may be obtained. (1) If it is desired to give the closet a small flushing, the handle 136 is operated. (2) If a full flushing is desired, the handle 36 is operated. If an eXtra large flushing is desired, both handles 36 and 136 are operated either simultaneously or successively, without permitting sufficient time between the two operations, for the first one operated to empty its Water space.

By using applicants invention, it is possible to construct the water connections with substantially all standard parts which may be purchased in the open market.

In the construction shown in Figure 2, a flanged T-connection 201 connected to a source of water supply. To this T-connection 201, are connected

pipes

202, 202, Flow regulating valves 203, 203W are provided for regulating the flow of water.

Controlled by the operation of the handles 204, 2041a are valves which control the admission of water from the water spaces within the

connections

205, 205% These valves are located within the fixtures 206, 206l which are connected to the upper ends of the respective pipes 207 207, These pipes 207, 207a connect at their lower ends to the pipe 20S which has au outlet 209 leading to the howl of a closet.

The valves which are located in the castings 206, 206, respectively and are operated by the

handles

204, 204, are of the usual lio-tank, slow-acting flush valves. In practicing my invention, however, one of the valves is preferably set so as to permit a smaller amount of water to pass in one operation than will pass during an operation of the other valve.

.Vhile I have illustrated and described embodiments of my invention, I desire to have it understood that I do not limit myself to the exact showing and that modifications and changes may be made without departing from the spirit of the invention and within the scope of the appended claims.

Having described my invention, what I claim and desire to secure by Letters Patent is 1. A closet 'flushing device comprising two `float valves and two seats with openings therefor, container walls forming separate water spaces for delivering water to the passage through each valve opening and a single closet connection having branches leading from the respective valve openings.

2. A closet flushing device comprising two float valves and valve seats with openings therefor, container walls forming separate water spaces for delivering water to each valve openin a single closet connection having branches leading from the respective valve openings and valve control means for selectively controlling the delivery of water from the water spaces through the valves whereby a greater amount of water will pass one valve when operated than will pass the other when the other is operated.

8. A closet flushing device comprising two float valves and two seats with openings therefor, a single closet connection having branches 'leading from the respective valve openings,

other walls forming separate water spaces for delivering water to each valve seat opening and for normally maintaining the same static pressure at each valve.

4. A closet flushing device comprising two float valves and two seats with openings therefor, a single closet connection having branches leading from the respective valve openings, container walls forming separate water spaces for the separate valves and a single valve-controlled duct for refilling either or both water spaces when lower than a predetermined level.

5. A closet flushing device comprising two independently operable valves and two seats with openings therefor, water container walls forming separate water spaces for delivering water to the respective valve openings and a single closet connection having branch passages leading from the respective valve openings, each valve and valve seat heilig so constructed as to prevent the passage of the water from the water space when the valve is seated.

6. A closet flushing device comprising a Valve, a seat for the valve and having an opening, a second valve and a second seat therefor, the second seat having an opening, a Water container having a space for delivering a predetermined amount of Water to and through a valve seat opening when a valve is opened and a Water container having a second space Jfor delivering a different predetermined amount of Water to and through the other valve seat when the other valve is opened, a. single closet connection having branch passages leading from the respective openingsv and a separate means for operating either valve at Will to draw Water from its Water space independently of the Water in the other Water space.

In testimony whereof I hereunto affix my signature.
