Specification of Letters Patent.

Patented M Application filed July 1, 1916. Serial No. 107,101.

To all whom it may concern:

Be it known that we, JOHN C. Cox and ERTHOLD V. OX, citizens of the United States, and residents of St. Louis, Missouri, certain new and useful Imollowing clear, and eXact description, reference being bad to the accompanying drawings, forming a part hereof.

d combination of parts hereinafter described and specifically pointed out in the claim hereunto appended.

ne of the objects of our invention is to provi cally delivering to the flush-tanks urinals and the like a liquid disinfectant, or germicide, each time the flush-tank is filled or emptied, wherehv the water used for flushing will b with a proper amount of disinfectant and germicide just after said tank has been disof closets,

germicide, and permitting the closet, or the urinal, to be thoroughly disinfected each time the flushing operation our invention is to provide improved means for mixing a liquid disinfectant or germ'icide with the water contained in the flush-tank as soon as said tank is refilled after it has been discharged, and

or maintaining in said tank such disinfected water as long mains in its normal filled condition, whereby the said body of disinfected water will act as a deodorizer and germicide for the air of the room.

.In the drawings:

Figure 1 is a vertical section of a portion of a common flush-tank having our invention applied thereto, and with the parts'in position as they appear after a flushing operation has taken place.

Fig. 2 is a detail horizontal-section, taken through the disinfectant-valve stem and its casing.

The numeral 1 indicates the usual flush- ;ank, for flushing a closet-bowl or urinal,

as said tank rede an improved device for automatisuitable quantity of body of I the same being supplied with ordinary well-known means for keepin water,-that trolled valve connected to water-supply (not shown).

0R FLUSH-TANKS.

and g it filled with is, with a common float-conthe source of tion, we locate the disinfectant or germicide tank, 2 above the said flush-tank 1, and

support the said disinfectant-tank in any known way, as upon the wall at a point tank.

Said disinfectant-tank 2 is a top l and a filling cap 5, top rises a end of wh A vertical rod 8 ally connected to one end of y means of a suitable pin or fectant measuring-chamber downwardly through openin of the said disinrectant-tank vertical bracket 6, to th 1011 is pivoted a lever 7.

has its upper end pivot by merely hanging it above the said flushprovided with an passes s in the bottom in said flush-tank cover 3, so that said measuringchamber within the Suitab mon clamp-nut 14 to form a tight joint measuring-chamber passes th tom of the said disinfectant he numeral 15 indicates said measuring-chamber bene tank cover 3, for holding th relative position.

Mounted at the lower en measuring-chamber is a said flush-tank 1 le packing-washers 13 and a comare made use of, as shown, at the point where said rough the bottank.

a clamp-nut on ath said flushe said parts in for controlling the exit-opening 17 of the said measuring-chamber.

Said exit-valve 16 is provided with the usual guide 18 for hat whenever its stem 1 the said float is the said flushtank the said valve will be opened, and be in said tank remains sufficient The numeral designates long as the level of the water ly high.

a vertical rod whose function is to loosely connect the floatarm 26 to the said lever 7, and permit a certain amount of play or lost motion between the said parts.

The lower end of the said vertical rod 25 is provided with an integral hook or eye 2 which engages the walls of a slot 28 formed in the said float-arm 26.

In the present case, the said vertical rod 25 passes through a guide-opening 29 formed in the said flush-tank cover 3.

The upper end of the said vertical rod 25 is threaded, and is provided with an adjustable nut 30, and said rod passes loosely through an opening 31 formed in the free end of the said lever 7.

A projection 32 is fixed on the said vertical rod 25, to contact with the underside of the said lever.

The operation is as follows:

The normal position of the parts is that in which they are shown. The fiushtank should be filled suliiciently full of water to keep the said float 20 elevated and the disinfectant exit-opening 17 of the said measuring-chamber open and in free communication with the water in said flushtank, in which position any disinfectant which might be contained in said measuringchamber would pass into and freely mingle with the water of said tank, and cause said water to act as a disinfectant and deodorizer for the air of the room in which said tank is located.

he disinfectant tank 2 should, of course, lie-supplied with a suitable quantity of any approved or well-known liquid disinfectant or germicide.

Whenever the said flush-tank is discharged, in flushing the closet-bowl, urinal or the like, the said float 2O falls, and carries with it its arm 26, which through the action of the levers 21, 22, closes the disinfectant-exit 17 by its valve 16; and such action takes place prior to the opening of the disinfectant valve 10.

As the float 2O continues to fall, the said vertical rod 25 passes downward until its nut 30 comes in contact with the adjacent end of the disinfectant-valve lever 7, and depresses said end of such lever, carryi g its opposite end (together with the said. vertical valve-rod 8 and valve 10) upwardly, thus opening the said disinfectant-valve, and permitting a definite quantity of disinfectant to run into the said measuring-chamber hence it will be discharged as before, upon the refilling of the said flush-tank with water.

The stem 19 of the said valve 10 is made non-cylindric as shown in Fig. 2, to facilitate the passage of disinfectant past said stem. The said stem 19 of the said disinfectant-valve 10 is made quite long, so that as the valve works up and down in its guide 18' at the upper end of the said measuringchamber 12, it will be guided in such movement, no matter how great the movement may be. r I r 7 7 As the water rises in filling the 'said flushtank, (with the parts in the position in which they are shown in Fig. 1) the said float-rod nut 30 will release the adjacent end of the disinfectant-valve lever 7 and the said valve 10 will close, cutting off the further passage of disinfectant to the said measuring-chamber 12, and then the said exitvalve 16 will be opened, permitting the disinfectant carried within said chamber to make its eXit therefrom and mingle with the water contained in said flush-tank, and be in readiness for another flushing operation.

The water in the flush-tank will act as a deodorant for the air of the room, in addition to thoroughly disinfecting the closetbowl, or urinal, or other thing into or upon which it may be discharged. The said flushtank cover 3, in order to permitthe odor o the disinfected water to pass into the room, should of course be open or partly cut away.

Our improved disinfectant dispenser. is very economical in the use of the liquid disinfecting-material, as it wastes none 0 i We do not limit ourselves to the exact construction shown in the drawings, as it is obvious that such changes can be made by skilled mechanics as are legally within the scope of our'invention. V

For instance, various materials may be made use of in practicing our invention, and the size and proportions of the various parts may be changed, ll without departing from the spirit of our invention. 7
