Nov. 4, 1930. c. w. BROWN CLOSET FLUSHING DEVICE Filed Jan. 21, 1930 Nonlaq Patented Nov. 4, 1930 UNITED STATES PATENT OFFICE CLOSET-FL'USHING I)EVICE Application led January 21, 1930. Serial No. 422,403.

This invention relates to 'lush tanks for toilets and has particular relation to those flushing devices Where a plurality of iushing means are provided to provide a variable amount of water supply for the Hush.

With the increase in the adoption of devices requiring water for their operation and due partly to the increase in population, there is arising, in some cities, a water shortage 1e which is causing the city engineers a great deal of concern. It has been determined that one cause for the large wastage of water is in the flushing of closets with a larger amount of water than would be necessary. In the use of flush tanks for closet iushing, it has been found that for some purposes, less than the full amount is sufficient, but that with the usual constructions of flush control devices,

the ball valve once having been lifted, it re mains oft of its seat until the tank is empty. If the floating valve is replaced by a valve which has to be held up, then careless persons will not take the trouble to see that a proper flushing takes place.

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

Another obj ect of the invention is the provision of such a differential iiushing device having a provision for releasing variable amounts of water and having a means for adjusting the amount of water to be used in the full flushing and also means for adjusting the amount of water to be released for a lesser ushing.

A further object of the invention is the provision of a plurality of delivery pipes having valves at their tops for providing variable amounts of water for iiushing and a means for adjusting the relative height of the valves, one to the other.

Another and still further object of the invention is the provision of such a flushing device having extensible fittings to provide for adjustments as to distance between the valves to take care of different types of tanks and as to height of valves to adjust for a minimum amount of water for the particular bowl 5 with which it is to be used.

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

Referring to the drawing wherein I have illustrated an embodiment of my invention,

Figure 1 is a front cross section of my invention.

Figure 2 shows a modified operating mechanism for my invention.

Throughout the specification and drawings the same reference characters will be used to describe and designate the same or similar parts.

The numeral 10 designates the tank which 65 is of the usual construction. v An inlet supply pipe 11 furnishes a water supply to lill the tank space to the predetermined level. A valve mechanism 12 of the usual construction controls the water entering through the pipe 11. A ball 13 is mounted on a rod 14 which is pivoted at 15 on a lever 16 which has a segmental slot 17. A wing nut and bolt 18 secures the rod 14 to the segmental slot 17 to hold the ball in any one of many adjusted positions. The lever 16 is fulcrumed at 19 and is connected by a link 2O to the valve lever 2l which controls the operation of the inlet valve mechanism in a well known manner.

To control a. full iushing, I provide the bulb valve 21 which rests on a, valve seat 22 above the outlet 23 to the closet bowl. The bulb valve 21 is held in proper position by a rod 23 which moves in an axial direction in the guide 24.

The guide 24 is supported from the overflow pipe 25. A releasing rod 26 operates the rod 23 to lift the valve 21 and is itself operated by the lever arm 27 connected to the handle 28.

Adjacent and below the valve seat 22 is a branch fitting 29 to receive the water comin from the second valve, about to be describe In order to vary the amount of a partial flushing for the closet bowl, the second valve seat designated 30, is located at one side of the valve seat 22 and in a position which may be varied, at will, as to height. This adjustable feature is important as it enables the user, by experiment, to determine the exact amount of water necessary for the desired results and to leave the parts set so that subsequent flushings will be of the same quantity of water.

The valve 30 is at the top of an adjustable tting 31 which in the embodiment shown has a sliding fit with a short length of adjustable pipe section 32. In order to hold the fitting 31 in ad'usted relation to the section 32, I have provi ed a water tight securing joint.

A packing nut 33 is of a shape to fit closely around the pipe section 32 and is screw threaded to the fitting 31. A packing 34 is held between the packing nut 33 and the end of the fitting 31 and makes a water tight connection between the two. In addition, this packing holds the

parts

31 and 32 in relative position. From the description of these parts it is clear that by pressing down or raising up, the height of the valve seat 30 may be regulated. On the bottom of the section 32 are preferably long screw threads 35 which coact with screw threaded surface 36 of a couplin 37.' The opposite end of the screw threaded surface 36 receives the screw threads of an elbow 38. The elbow 38 receives one end of a threaded nipple 39, the other end of which is threaded in a T-fitting 40. The opposite end of the T-itting is connected by a nipple 41 which is threaded in the fitting 29.

By adjustment of the

nipples

39 and 41 within their threaded connections, the device v as a whole may be ada ted for different sizes and types of tanks havlng the flushing` handle means in various places.

By adjusting the part 32 relative to the part 37 and the latter with relation to the elbow 38, various heights may be obtained. If necessary, different lengths of pipe 32 or couplings 37 may be used.

The variations of the adjustments of the pipes and

fittings

31, 32, 37 and 38 and the substitution of various lengths of the parts is for the purpose of obtaining different heights for the valve seat 30.

A valve 42 carries a rod 43 which is guided in the guide 44 supported from the overflow pipe 25. A lifting rod 45 is lifted by the lever arm 46 which is operated by the handle 47 in a well-known manner.

The bulb valve 42 rests on the valve seat 30. When the valve seat is adjusted, the guide 44 is correspondingly adjusted along the overiow pi e 25 which is supported in the T-itting 40. he lifting rod 45 which is a bent iece of wire can easily be bent to provide fbr lifting the guide rod 43 at the proper time.

At the time of installation, by trial, the level of the water is adjusted by loosening the wing nut 18 and adjusting the height of the ball by the relation between the lever 16 and the rod 14. The wing nut 18 is then tightened. The height of the water should ready described.

When itis determined that the valve 42 and its valve seat are in proper relation to the surface of the water in the tank, then these parts are left in their positions and the proper adjustments of the parts 44 and 45 are made.

In installing the device asa whole, in a tank the adjustment of the

parts

29, 41, 40, 39 and 38, places the parts so that they may conform to the position of the operatin handle 47 and the position of the tank wal In Figure 2 I have illustrated an embodiment of the invention showing a different form of operating means. In this form the

parts

26 and 45 are the lifting rods for the valves as already described for Figure 1. In this form, however, the lifting

arms

127 and 146 are integral with a pivoted operating handle 147 which may be moved in one direction for a large or full flush and in the other direction for a partial iush. In practice, suitable indicia would be placed on the tank to indicate the direction of movement to produce the desired results. The movement in one direction, for example clockwise would lift the lifting rod 26, the guide rod 23 and would cause the operation of the valve 21 in a well known manner.

At the same time, the lever arm 146 in moving downwardly would simply permit the eye at the lower end of the lifting rod 45 to slide downwardly over the rod 43 with no resultant action. This would cause the bulb 21 to be lifted and due to its slidinv connection with the lifting rod 26, would tend to float until the tank was emptied.

After the tank is again full, the same action in a counter clockwise direction will lift the valve 42, deliverinv' the water to the level of the valve seat 30, down through the passage in the

fittings

31, 32, 37,38, 39, 40,41, 29, 22 and 23. No water below the level of the valve seat 30 will be d ischar ed.

As in the previous case, wit the lowering of the water level, the ball 13 lowers and opens the valve 12 and admits the water until the ball 13 raises to a predetermined level and closes the valve 12.

A refilling pipe 48 is connected to the valve 12 and extends to the overfiow pipe in the usual manner. This refilling pipe is useful in the present structure as it has a. tendency to always have the level of the water, in the t the same degree of flushing repeate bowl, at the same height when the

valves

21 and 42 are operated. This tends to 1 While I have described and illustraad, in detail, an embodiment vof my invention, I desire to have it understood that the disclosure is merely illustrative and that modifications and changes can be made without departing from the spirit of the invention and within the scope ofthe ap ended claims.
