MEANS OR APPARATUS FOR SUPPLYING LIQUID DISINFECTANTS TO THE WATER CON- TAINED IN TANKS USED FOR WATER-CLOSETS AND OTHER LIKE FLUSHING PUR- POSES.

Application filed May 12, 1928, Serial No. 277,279,. and in Great Britain May 20, 1927.

This invention relates to improvements in means or apparatus for automatically regulating the flow of liquid disinfectants to the water contained in a tank or cistern or other termed and included in the term the cistern,-employed for water closet and other like flushing purposes.

The type of apparatus to which this invention'is particularly applicable is that in which thereceptacle in which theliquid disinfectant is placed is separate from, or arranged on or in thecistern' It is preferred to attach the receptacle to and above the cistern and to provide means for an intermittent automatic supply of liquid disinfectant to the water in the cistern. 7

In carrying this invention into practice the disinfectant receptacle may be made in a form in which the mechanism for operating and controlling the flow of disinfectant to the water in the cistern is arranged within the receptacle in which the liquid disinfectant is placed. A

In the drawings hereunto annexedz Fig. 1 a front and sectional elevation of a form of apparatus in'which the mechanism for operating and controlling the flow of the disinfectant is arranged within a compartment formed within the receptacle employed for containing the said liquid.

Like parts in all the views aremarked'with similar reference numerals. H y p 1 is the cistern which may be made of metal or of wood linedwith sheet lead orany-other f suitable material and itis made of the usual and ordinary shape andconstruction. As illustrated in the drawings the cistern 1 is shown with an open top,but when required it may be provided with a fixed or adjustable cover. 7 v v a r 3 is the receptacle for the liquid disinfectant. hereinafter termed disinfectant,-

and it is made in one or more portions of any suitable material that will not be injured the ch r'mcal act on of thedisinfectant. snitehiaftaetetiat fer recept .351;

is made of any required size and shape,-is cast or formed of sheet orother metal pressed or formed to the required shape, or it may be formed of glazed earthenware.

At the bottom 7 of each end of the receptacle is provided a lug, or flange 4' which projects in an outward direction and also is level with the bottom of the receptacle. The lugs or flanges 4:, 4', provide means whereby the receptacle 3 is fixed, say, by screws 5, 5, to the upper surface of the cistern 1. The receptacle 3 is made rectangular with

vertical sides

9, 9 and

ends

10, 10 and it is provided with an open top which is closed by a fixed 0r detachable cover 11. The bottom 7 of the rece tacle 3 is made level.

In the side 9 of the disinfectant receptacle 3 is formed a vertical opening 12 which extends downwards from the open top 6 of the receptacle to or within a suitable distance I of the bottom 7 thereof, and a verticalpartition 13 is provided in the interior of the receptacle 3 which extends from the said top to the inner surface of the bottom 7 of the receptacle. The vertical partition 13 extends a suitable distance from the end 10 of the receptacle to beyond the opening 12 as shown at 2. The vertical partition 13 is arranged parallel with the side 9 of the receptacle 3. The space 27 between the inner surface of the vertical partition 13 and the inner surface of the side 9 of the receptacle 3 is closed by an end piece 14 which does not extend to the top of the vertical partition 13 and the top of the receptacle 3'Figs. 2 and 3.

By making the end piece 14 shorter in depth than the vertical partition 13 a cavity is mounted upon a bolt 18,'having nuts 30,

31 on its ends,which passes through the boss 19 of-the said lever, and the outer and free end of the horizontal arm 16 is slotted or bifurcated, for permitting of the reduced and screw threaded end 20 of the vertical valve rod 21 to pass through it, A nut or ployed for adjusting the position of the ver tical valve rod 21. The lower end of the rod 21 is reduced in size or diameter for forming a valve 22 which is adapted to work against the seating 23 formed in a flanged boss 25 formed on or fixed by a collar 25* to the upper surface of the bottom 7 of the receptacle 3. A central hole M is arranged to pass through the boss 25 which is formed on the surface of the bottom of the receptacle for the discharge of the disinfectant into the water within the cistern 1.

A blcck,hereinafter termed a cam piece 26,is arranged to work in the space 27 between the inner surface of the side 9* and verticalpartition l3 and the cam piece is mounted on the pivot 28 and which is in the form of a spindle provided with screw'threaded ends upon which are mounted respectively the

nuts

32, 33. The cam piece 26 has a V shaped recess 26 formed. in its periphery whereby a double cam is provided, one portion of which acts against the outer surface of the pendantarin 1.7 an d the other portion of the "cam is acted upon by the inclined surface of the disc 29. The cam 26 is mounted loosely upon its pin or spindle 28 so as to enable it to act as a tripping device for intermittently acting upon the outer surface of the arm 17 andfthe position of the V shaped opening 26* is so arranged that one portion of the cam is heavier than the. other for enabling it to act as the weight for returning the cam to its normal position.

To the bottom 7 of the receptacle 3 is fixed a tubular pendant bearing 34,Fig. 1,- which is of the same internal bore as the pipe 36 fixed within the float 35. The float is cylindrical in form and closed at both of its ends which are connected centr'ally together by the pipe 36. On the top of the floatis fixed by soldering or other means a boss 37 provided with acentral hole of the same diameter as the internal bore of the pipe 36 through which passes a vertical rod- 38 in which the float is adjustably fixed by a set screw 39. The vertical rod 38 passes through the pipe 36 and also project's beyond the top of the float 35. To the upper end of the rod 38 is fixed the disc 29 against which the minor portion of the cam 26 acts. The disc 29. rises and falls in the space 27ofthe receptacle 3 simultaneously with the rise and fall of the float 35 the movement of which is controlled by the rising and falling levels of the water in the cistern 1;

On the descent of the vertical rod, 38 and the float 35' which is attached thereto. as described,during or after the discharge of the flushing water has taken place,-the inclined periphery ofthe disc 29, acts upon the portion at the front of the cam 26 forraising j the vertical rod 21 and lifting the valve portion 22 of the rod clear of the valve seating 23 for allowingthe required supply of di$- infeetant to pass through the discharge opening 24 to the water in the cistern 1.

During the movement of the cam 26 the periphery of its major portion will act upon the pendant arm 17 thereby raising the horizontal arm" 16 which lifts' 'the 'rod 21. Sheet taneo'usly the float permits of the rod 38 to descend with the flushing water in'the receptacle 1. During the descent of the rod 38 and as soon as the inclined periphery of the disc 29 is clear of the front portion of the cam 26 its weighted portion and the levers 16 and '17 will return to their normal position for permitting of the vertical rod 21 and the valve 22 to descend upon its seating 23 for cutting off the supply of disinfectant to the water in the cisternl; As soon as the water is again allowed to flow into the cistern 1 by means of the ordinary belltap, the float 35 will commence to rise and by it being secured upon the rod 38, the float 35 and disc 29. will all be raised simultaneously. Onthe upper surface of the disc 29 coming in contact with the minor portion of the cam 26, the latter will be raised a sufficient height to permit of the disc 29 being raised into the position shown at Fig; 1. During the just described tripping motion of the cam 26 no movement of. the rod- 21 takes place until the inclined periphery of the disc 29 on'its descent again comes in contact with the minor portion of the cam 26, as previously described.
