1 Claims. (01. 4-221) The invention concerns a device adapted to be installed in the conventional tank of a, closetin order that upon operation of the flushing valve a cleansing and deodorizing solution willauto matically be fed into the stream of water discharged into the bowl. The'entrained solution enables the bowl to be kept in a clean and deodorized condition.

The invention has. for itsobject to produce a device so constructed and arranged that a submerged reservoir'is filled with Water from the tank supply and forced upwardly by an air trap so as to impinge an elevated chemical compound in the form of a cake or mass. The chemical compound is composed of well known ingredients which are for the purposeof this invention combined into a loosely packed cake or brick so that the elevated water will partially disintegrate .it and thus form a solution. The solution is caught in a chamber provided with a'syphon which .automatically discharges a portion .of it down the usual overflow pipe upon foperation of the flushing valve-of the tank. l I

A distinctive. advantage of the invention is-that it is entirely automatic. in itsoperation and that it has no moving parts-that are-likely to get out of order. The device is inexpensive tomanufacsure, and a cake orbrick'of the chemical compound will last foraconsiderable length of time before having to be replaced.

Figure. '6 is a cross section Qrngure 5 taken-on line 6'6 thereof, and Figure 7- isla cross section thereof taken on line l1. Y

V Likenumerals of reference indicate corresponding partsv in each of the figures throughout the drawings of the invention. v I a In describing the invention ingreater detail, the gprefrerred form showni-n Figures 1 to 4; in elusive will first be recount-ed;

The'reference numeral 8 denotes .a standard flush tank which is mounted above the bowl ofa closet for discharge through the flushconnection 9 provided with the usualfloat valve ll] of which this arrangement the solution is drawn off from the rubber float l'l forms a part. The .float of course is tripped in well known manner each time. the bowl (not shown) .is to be flushed.

The regular overflow pipe is shown at l 2, which pipe communicates at its base with the'flush 5 connection for the purpose of taking care of undue rise in the level of the Water contained in the tank, and controlled by the ball-cock, which is not shown since it does not form a part of the present invention. The normal level of the 10 water in the tank is denoted at I3.

The device of the present invention is suitably supported in the tank alongside of the overflow pipe 12 .and comprises a cup-shaped chamber or solution receptacle I4 of whichthe open top If supports a perforated plate I6. A convenient expedient for supporting the plate consists of an annular ledge -Ifl inside the top of the chamber and formed by crimping the metal sidewall thereof. V The plate rests upon the ledge H in order .to seat thechemical compound which is in the nature of a cake or brick l8 as aforesaid. The plate preferably has a large central hole [9 encompassed by several small holes as at 20..

A .tubular cylinder 2| is attached to and depends from the bottom of the solution receptacle I4. The upper end of the cylinder is closed by the receptacle. The lower end'however is'open and disposed in spaced relation to the floor of 30 the tank. The cylinder constitutes an air trap as will be later explained.

Wi'-thin the cylinder and spaced from its top is a. cup 22 of a smaller diameter than the cylinder bore so as to provide an intervening passage 23 {55 The cup is rigidly attached by suitable means such as denoted at 24.

Vertically mounted in the cylinder is an eduction tube 25 having its lower end open and disposed within the cup 22 at a distance from its bottom. The tube extends upwardly through the solution receptacle l4 and terminates in an open top slightly below the plate l6 in alignment with the central opening I9 therein.

The solution receptacle is furnished with a. syphoning tube 26 laterally disposed with the short end protruding downwardly through the upper part .of the sidewall and the long end projecting. into the Yoverfiow pipe. l2 for emptying therein. The short end is fitted in a duct 21 vertically arrangedand in communication with the interior of the solution receptacle by means of the aperture 28 at the bottom thereof. By

the bottom of the receptacle where it is better commingled.

Having described the invention, its operation will now be recounted: Following the installation of the device, the initial filling of the tank serves as a primer for the cup 22 so as to fill it with water. It will be understood that in this initial filling, the water in rising to its usual level, indicated at I3, will freely rise in the cylinder 2| and thus fill the cup 22. The water within the cylinder flows out in the flushing of the bowl. As the tank refills and the water level rises above the lower end of the cylinder 2|, it

exerts pressure upon the air trapped therein, which is sealed off by the Water in the cup. As

the pressure increases with the rise of the water in the tank, the water held in the cup is subjected to sufficient pressure to expel it through the eduction tube 25 along with the entrained air. As the educted water emerges from the top of the tube it sprays upon the bottom of the chemical compound causing partial disintegration that results in a solution that is caught in the chamber [4.

The device is so proportioned that several flushes of the tank are required to fill the chamberwith the solution, of which the final flush causes the solution to overflow in the syphon tube 26. This automatically discharges into the overflow pipe I2 until syphoning is cut off by the lowering of the level of the solution in the receptacle M. The solution thus discharged gravitates to the bowl and the next flushing oper ation produces an additional amount of the solution and serves to cause a recurrent syphoning of the solution to the overflow pipe.

Adverting to the modification shown in Figures 5 to 'l'inclusive, the variation in the structure consists in' providing a cup 29 around the top portion of the tubular cylinder 30. The cup constitutes a reservoir which is filled with water enteringthe cylinder in the refilling of the tank. The eduction tube 3| in this case has its lower extent offset so as to lead into the cup, as depicted in Figure 5.

The operation of this slightly modified structure is precisely the same as the preferred construction above recounted.
