PATENT OFFICE.

DEODORIZER.

SPECIFICATION forming partof Letters Patent No. 650,161, dated May 22, 1900-. Application filed September 2, 1899. Serial No. 729,333. (No model.)

To all whom it may concern:

Be it known that we, J osEPH WILLIAMs, WILLIAM H. WILLIAMS, and EDWARD R. WIL- LIAMs, citizens of the United States of Amer ica, residing at Sharpsbu rg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Deodorizers, of which the following is a specification, reference being had therein [0 to the accompanying drawings.

This invention relates to certain new and useful improvements in deodorizers, and relates more particularly to that class known as siphomoperated chemical disinfectants.

The herein-described invention is designed and adapted to be used in connection with flushing-tanks for closets, urinals, and the like.

One object of the invention is to provide novel means that will permit of the chemical disinfectant being used in the most economical manner and to automatically operate and distribute the disinfectant by means of the rising and lowering of the water in the flush- 2 5 ing-tank.

The invention further contemplates to construct an apparatus of the above-described class that will automatically and accurately regulate a certain amount of disinfectant to be discharged with each operation of the valve in the tank.

A still further object of our invention is to form a water seal at a certain predetermined point in the vent-tube, thereby preventing 3 5 the disinfectant being discharged too freely,

which would greatly reduce the lifetime of the apparatus.

Another object of our invention is to construct an apparatus of this class that will possess advantages in points of simplicity, durability, practicability, and cheapness 0f manufacture.

With the above and other objects in View the invention, briefly described, consists of a suitable receptacle containinga soluble chemical disinfectant, with the receptacle having a siphon and air-tube removably attached thereto. The air-tube and other parts are constructed in a novel manner to be hereinafter more particularly described, and specif ically pointed out in the claim.

WVe will now describe the particular form of apparatus, reference being had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate like parts throughout the several views, in which- Figure 1 is a vertical sectional view of a portion of a flushing-tank containing our improved siphon-operated chemical disinfector and indicating in dotted lines the water-level in the tank. Fig. 2 is a similar view showing the water discharged from the tank. Fig. 3 is an enlarged perspective view of our improved apparatus. Fig. 4 is a similar view showing the siphon and air-tube detached. Fig. 5 is a perspective View of the screwthreaded cap. Fig. 6 is a similar view of the cap, showing the siphon and air-tuberemoved therefrom. 7

In the drawings the reference-nmneral 1 ii1= dicates the flushing-tank.

The reference-numeral 2 indicates the receptacle, carrying on its upper face an annular screw-threaded flange 3, forming an opening 4, communicating with the interior of the receptacle. A cap 5, carrying an annular flange 6, is adapted to fit in the opening 4, said cap 5 being further provided with a siphon tube 7. This siphon tube extends through the cap 5 downwardly a short distance into the receptacle and is bent over, as shown at S, and thence extends downwardly a short distance below the end of the tube extending into the receptacle. The cap 5 is further provided with an air-tube 9, the upper end of said air-tube being bent over, as shown by the reference-numeral 10.

The operation of our improved siphon-operated chemical disinfector is as follows: For 0 the purpose of clearly illustrating the operation we will assume that all parts are in the position shown in Fig. 1 of the drawings, the water-line in the flushing-tank being near the top thereof and the receptacle submerged 5 therein, as shown. The receptacle is retained in proper position on the bottom of the tank by reason of the soluble chemical disinfectant therein-for example,'soluble thymol being of greater specific gravity than the wa-' I00 ter. WVhen the valve of the flushing-tank is opened and the water allowed to escape, no

discharge ofthe disinfectant is obtained until I the water-level in the tank is equal to .the

liquidslevel in the receptacle. At this point the solution formed above the chemical will siphon'into the water in the tank until the water-levelin the latter is equal ,to t he .end of the downwardly-extending siphon tube in the receptacle, when the water in the tank will be further discharged, but only a small amount of the solution will be siphoned from the receptacle.

We will now proceed to descrlbe the reverse or charging operation, in whichzthelimpors tance of our submerged air-tube creating a water seal will be ful'ly'seflfofth." W'ewill' assume that the water is drained or nearly drained from the flushing-tank, and it will be-- observed that as the soluble thymol is heavier than water it remains at the bottom ofvthe-receptacle. As the water rises in the flushing-tank it will enter the receptacle through the siphonrtube and come into contact with the soluble thyme], forming a disinfecting solution which is of about the same specific gravity as the water, but more volatile than the thymol. Hence it is constantly emitting an odor into the atmosphere if the air tube is straight or not submerged in the manner as heretofore set forth; but when the'end of this air-tube is bent over a water sealis obtained by the water enteringsuch bent-over portion as thewater rises in the tankyand the odor which would otherwise escape is-retained in the receptacle until the tank is again flushed, when it will be, together with the volatile solution, siphoned from the receptacle into the flushing-tank, as heretofore described. Particular attention is called to the fact that it the-air-tube is not. submerged -the solution upon the top of the thymol is constantly emitting its odor and strength into the-atmosphere, drawing its supply from-the thymol and causing a continu al waste, which is overcome by providing a waterseal obtained by the construction of asubmerged air-tube in the manner heretofore-referred to.

- In view of the foregoing description with reference to the accompanying drawings others skilled in the art will be enabled to readily understand the construction and practical -opera-tion or our improved apparatus, and it is thought thata further description of the parts is unnecessary, except that in case it is desired to pack the apparatus for shipping the siphon is removed from the recepta cle. .....An interim: cap is provided similar to the ex ception of the openin gs formed therein, and the screw-threaded cap (shown in Fig. 5 of the drawin gs)en gages the exterior screw-threaded flange 3 and seals the opening tof the receptacle. It will be,noticed thatvarious forms of receptacles, siphons, and connections may be *used when applyin'g'our apparatus to various forms of flushing-tanks without departing from the general spirit of our invention. Having fully described our invention, what we claim as new, and desire to secure by-Letters Patent, is-

The combination with a flushing-tank, of a receptacle within the tank and supported on the bottom thereof and adapted to contain a disinfectant compound, said receptacle being provided with an opening in its top, anannular screw-threaded flange secured to the top aronnd'said'opening, aclosure-cap engaging in said flange and provided with a pair of eccentricallyplaced openings, a siphontube secured in one of said openings with its shorter leg extending downwardly into the receptacle and its longer leg extending downwardly outside the receptacle, and an airtube secured in the other of said openings in the closure-cap with its lower end flush with i the underneath face of said cap and its upper end bent downwardly whereby a water seal is eifected to prevent the discharge of the disinfectant or odor therefrom into the water in the flushing-tank or to the atmosphere until the tank is flushed or drained, as and for the purpose described.

Intestimony whereof we aflix our signatures in the presence'of two witnesses.
