Application September 17, 1952, Serial'No. 309,938

9 Claims. (Cl. 248-224.)

This application is a continuation-in-part of my application Serial No. 131,679 filedDecember 7, 1949, now abandoned.

The invention relates generally to dispensers-used in toilet flush tanks for supplying to the water in the tank,

each time the toilet is flushed, a small quantity of a liquid which has sterilizing, disinfecting, deodorizing and/or cleansing properties, such dispensers being of the type shown in the E. A. Strattrnan Patent No. 2,021,110

One object of the invention is to provide an extremely simple and practical device of this character-which will .permit the chemical liquid tank or reservoir tobeproperly suspended from the upper edge of at least one of the four, walls of the flush ta-nkwithout interference with any of the tank fittings, so that the dispenser may be, I

mounted in any of the present day toilet tanks.

.Another object of the invention is to provide a suspending means for the reservoir employing a single detachable hanger with a centering connection to the res- .ervoir so that'the latter will be supported in a horizontal position without danger oftilting and whichwhen detached may be placed within the reservoir together with thefloat-valve parts, thus providing -a compact assemblage inserted in a small carton for mailing.

Another object is to provide a single'hanger which is quickly and easily applied to-the reservoir and which willbe removably locked to it by a snap action so that there will be no liability of the reservoir being lifted or moved upwardly from its normal position by the action of waterin the flush tank .upon the fioat valve.

With the above and other objectsand advantagesin View, the invention resides in :the novel combinations .and

arrangements of parts and the novel features of construction hereinafter described andclaimed, and illustrated in the accompanying drawings which show the present preferred embodiment of the invention.

Fig.5 is a detail section on line 5- 5 of Fig. 3 but wall of a toilet flush tank or other liquid vtank within which the improved device is suspended. 10 denotes, as a whole, the improved receptacle or container for a liquid L which is to be dispensed into the water or other liquid in the tank T. The liquid L is preferably one which has sterilizing, disinfecting, deodorizing and. cleansing properties, so that the toilet will be kept in a clean, sanitary and odorless condition. A small quantity of this watertreating or chemical liquid is dischargedinto the water of the main tank each time the toiletis flushed, by the float-valve structure which is shown in Fig. 2 and which is claimed in my application Serial No. 153,260 filed March 31, 1950 andissued December 2, 1952 in Patent No. 2,620,097 for Plastic Dispenser for Disinfectants and the Like.

The receptacle or reservoir 10 is in the form of, a. generally rectangular tank molded in one-piece from polystyrene or other suitable plastic which preferably ,has some resilience or elasticity. The reservoir 10 has v.an open top, side walls 14, 15 and end walls 16, 17, said walls being upwardly and outwardly flared and .being united by a curved or dished bottom 18 having a sump or depression 19 adjacent its central portion.

Since toilet flush tanks are of various sizes andconstructions, and contain variously arranged fittings or fixtures, and since it is desirable to suspend the small tank or reservoir 10 according to the normal water level in the tank T, I have provided a novel hanger 20 and means .for connecting it to one upright wall of the reservoir 14), so that the latter may be quickly, easily andprop- ,erly mounted in practicallyany kind of toilet flush tank and withoutregard to the location of the fittings in the same. The hanger 20 preferably comprises a generally rectangular sheet of thin pliant or bendable material such as aluminum which is corrosion resistant or coated to resist corrosion. Its upper portion is adapted to bevbent over and around the upper edge of the flush tank wall T as at 21 in Figs. 1 and 2. Its lowerend is detachably connected to the reservoir as hereinafter described. The reservoir or tank 10 is small as compared to the flush tank since only a very small quantity of the chemical liquid need be discharged into the water eachtimethe toilet is flushed. In its preferred form the reservoir has a length of about 6 inches, a width of about 2 inches andan over-all height of about 2 /2 inches so that it may be enclosed in a small carton. By makingthe hanger detachable it may be placed within the reservoirtogether with the float-valve parts presently described and thus all parts of the dispenser will be compactly arranged in a small carton. The hanger has a width of about 2 inches and a height or length of about 4 inches but is amply long enough to permit at least a portion of its vupper end to be bent over one of the upright walls of the flush tank and have the reservoir disposed above the normal water level in the flush tank. By making the reservoir small and using a single hanger, the devicemay be disposed along either the front wall or the back Wall .or'either of the end walls of the flush tank depending upon the location of the fittings or fixtures within the latter.

The detachable connection between the hanger 20v and the reservoir 10 comprises a pair of laterally opposed hook-like projections 23 engageable with a pair voflaterally opposed lugs 25 formed on at least one of the side waLls of the reservoir. The projections 23 are formed by cutting out angular recesses in the side portions. of the hanger, as will be seen on reference to Fig. 4,.and then bending outwardly the lower ends of thedownwardly extending projections to form the oppositely inclined supporting flanges 24. The latter provide twoupwardly facing shoulders inclined in opposite directions. As shown they are inclined upwardly and inwardly and they are adapted to engagesimilarly inclined loweredges of the lugs 25. The lugs 25 are of triangular shape and are flat and disposed in the same plane which is spaced outwardly, as at,26, from the flat side wall 14 a distance slightly greater than the thickness of the hanger 20, such thickness being preferably .020. The lugs project toward each other from the upper ends of a pair of vertically extending ribs 27 molded on the side wall in horizontally spaced relation. The ribs 27 which stiffen the side wall are equally spaced from the longitudinal center of the wall 14, their spacing being slightly greater than the width of the hanger. By making the width of the hanger approximately one-third of the length of the reservoir, a single hanger may be used. Thus the reservoir and its contents will not only be effectively supported but will be centered on the hanger due to the engagement of the oppositely inclined lower edges of the lugs 25 with the correspondingly inclined supporting shoulders or flanges 24 of the downwardly extending hooklike projections 23. The outer faces of the reenforcing ribs 27 are substantially perpendicular to the flat top of the reservoir, as seen in Fig. 2 and at least their lower ends will bear against the inner face of the flush tank wall T to hold the reservoir substantially level.

For the purpose of locking the reservoir to the hanger so that the action of the water in the flush tank on the float valve will not tend to lift the reservoir, two detents 28 are provided at the side edges of the hanger to snap over the upper edge of the wall 14 just prior to the engagement of the shoulders 24 with the lower edges of the lugs 25. These detents are formed by making small slits 29 in the edges of the hanger and bending rearwardly the metal above the slits. While the aluminum sheet from which the hanger is made is pliable it also has a slight amount of resilience or elasticity. However, the aluminum sheet, which has a rather snug fit between the lugs 25 and the opposed portions of the wall 14, is placed under some tension by bending rearwardly the lower edge of the sheet to form a horizontal flange 30. The edge of this flange engages the outer face of the wall 14 after the upper end of the hanger has been slid upwardly beneath the lugs 25. The width of the flange 30 is such that the lower portion of the hanger is placed under slight tension and when the detents 28 pass above the upper edge of the wall 14 they will snap over or above the latter. Thus the reservoir will be locked to the hanger and can have no substantial vertical movement upon it after the detents are disposed above the upper edge of the wall 14. The hanger 20 will be shipped to the purchaser in the condition shown in Fig. 4, and all the user has to do is to upwardly insert the upper end of the hanger beneath the lugs 25 and slide it upwardly until the detents pass above the top of the wall 14 and the shoulders 24 are engaged with the lower edges of the lugs. The legend This Side Out is stamped on the hanger to insure the proper engagement of it with the reservoir by the user. The two circular holes in the hanger shown in Fig. 4 are provided merely to facilitate its manufacture.

The float valve structure shown in Fig- 2 forms the subject matter of my above noted Patent No. 2,620,097. It comprises a bell shaped float 44 molded on the lower end of the stem 35 of a double valve 36. The stem has a loose sliding fit in a tubular guide 34 depending from a tubular or cup-shaped member 33 into which telescopes a tubular member 30' molded on the center of the bottom 18 of the reservoir. These tubular members are substantially cylindrical but tapered so that they will be held together by friction. A curved or dome-shaped partition 31 extends across the upper portion of the member 30' and its upper surface forms a part of the sump or depression 19. The telescoped members, and the partition form a measuring chamber 32 in which the valve 36 moves between two seats 38 and 43. The seat 38 is an annular bead formed on the bottom of the partition 31 around an outlet opening 39 of the reservoir. The seat 43 is an annular bead formed on the bottom of the cup or member 33 around the opening through the guide tube 34. While the double valve may be a ball it is preferably of the disk type and cemented on the upper end of the stem 35. In the top of the cylindrical valve head 36 is a socket to receive an elastic plug of neoprene or the like to engage the seat or bead 38 to effectively pre vent the passage of the liquid through the valve opening 39. On the bottom of the head 36 is an annular groove 46 to receive the lower seat 43 when the valve is in its lower position.

The dispensing reservoir is suspended in the flush tank so that the normal water level is a little below the bottom of the reservoir as seen in Fig. 2. That may be easily done after the hanger is fastened to the reservoir by bending more or less of the upper portion 21 of the hanger over the top of one wall of the flush tank. The float 44 being thus submerged will hold the valve on the upper seat. When the toilet is flushed, the float will descend as the water level drops, and the valve will then move into engagement with the lower seat and permit the liquid in the reservoir to fill the measuring chamber 32. As the flush tank refills the float will move upwardly to force the valve against the upper seat and the small amount of liquid in the measuring chamber will flow down into the water between the stem and its guide as indicated by the arrows in Fig. 2. That operation of the valve is repeated each time the flush tank is emptied and refilled.

It will be noted that the hanger provides an extremely simple, inexpensive and effective means for quickly and easily suspending the reservoir at the proper level in any accessible space around the upright wall of the flush tank. The dispenser may therefore be mounted in any of the flush tanks now in use, and no tools are required to assemble the parts or mount the reservoir, although when the hanger is applied to the front or an exposed end wall and its bent end extends below the rim on the flush tank cover (not shown) a pair of shears may be used to cut off the protruding end of the hanger so that the device will not mar the appearance of the tank.

From the foregoing, taken in connection with the accompanying drawing, it will be seen that novel and advantageous provision has been made for carrying out the objects of the invention, and while preferences have been disclosed, attention is invited to the possibility of making variations within the scope of the invention as claimed.
