JOHN TV. SCHELL, OF PHILADELPHIA, PENNSYLVANIA.

AUTOMATIC DlSlNFE-CTOR.

'SPECIFICATTON' for'r'ning part of Letters Patent No. 633,390, dated September 19, 1899.

Appli ation filed March 19,1398. Serial No. 674,425. (No model.)

T0 at whom it may concern.-

Be it known that I, JOHN XV. SCHELL, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Automatic Disinfectors, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists in an improved construction of automatic disinfector which is especially adapted for use in connection with water-closets, urinals, tanks, the, provision being made for enabling the disinfector to be come operative only when the closet is flushed and means being also provided for measuring the disinfectant, if desired, whereby onlya certain predetermined quantity thereof will be directed into the water-closet or bowl.

It further consists of novel features and details of construction, all as will be hereinafter fully set forth, and particularly pointed out in the claims.

Figure 1 represents a vertical sectional view of an automatic disinfector embodying my invention, certain of the parts being shown in elevation. Fig. 2 represents, on an enlarged scale, a section on line 00 :0, Fig. 1. Fig. 3 rep- .resents a similar view to Fig. l, but showing a somewhat modified form thereof. Fig. 4 represents, on an enlarged scale, a sectional view of a valveemployed.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, 'A designates an automatic disinfect-or, the same consisting of the usual flushing-tank B, which has a pipe or conduit G leading therefrom to any desired pointsuch, for instance, as a water-closet or urinal. The flow of water from said tank through the pipe 0 is controlled in any suitable manner or with the ordinary floatD and other necessary or desired mechanism; but as the'saine forms no part of the present invention a detailed description thereof is not here deemed necessary.

E designates a reservoir which may be located at any desired-point with relation to the closet bowl or other objective point, where it is rigidly secured against displacement in any convenient manner, saidreservoir being charged with the disinfectant fluid F and the discharge of the latter being controlled by means to be hereinafter referred to.

G designates a valve-rod which is shown in Fig. 2 as having at its lower end a valve H, adapted in its normal position to remain upon a seat M of a shell or casing N, within which casing is formed a chamber P to receive the disinfectant from the reservoir E. \Vhen the reservoir E is located at a distance from or below the tank B, the disinfectant is allowed to flow from the valve-casing N through a suitable pipe which leads fromsaid casing to the bowl of the closet or other objective point, when the valve or valves are moved by mechanism hereinafter described. In Fig. 3 the valve-rod G has a single valve G attached thereto, said valve controlling the port Gr in the casing G.

The upper end of'the rod G is pivotallysecured to a lever B, which is fulcrnmed to a bracket S, the other end of said lever being pivotally attached to a rod or sleeve T, which passes through a guide W, its lower end being connected in Fig. 3 to the'inverted cup or receptacle O which is provided with a flapvalve C normally covering an aperture 0 through which the air accumulating above the water and between the inner upper portion of the cup or receptacle O may be allowed to escape as the water fills the tank B and passes into said cup or receptacle.

A spring B is placed upon the sleeve '1, one end of which is secured to the guide TV, while its opposite extremity is fastened to a collar A, secured to the sleeve T, the function of said spring being to raise the cup or receptacle 0 after the water has flowed therefrom or at other desired periods.

One end-of a chain W is secured to the valve 0 and the other end is fastened to a suitable point, as the guide Y, through which the rod X passes, which latter engages the cup (J and is secured in the sleeve T by means of the collar and set-screw Z, said chain being adapted to open the valve 0 at the proper interval in order that the water contained therein may flow therefrom as it leaves the tank, it being apparent that when the chain becomes taut and the cup or receptacle continues in its descent the valve 0 will be raised to allow the air to enter, in consequence of which said cup will empty at the l desired moment and rise through the action of the spring B referred to, thus closing the valved outlet leading from the disinfectantreservoir and stopping the discharge of the fluid.

hen the mechanism is operated to flush the closet, the water as it flows out of the tank B will create a suction within the cup or receptacle, and until this suction is broken it will continue to descend, thus raising the valve H from its seat and permitting discharge of the disinfectant until such time as the chain \V, as above described, opens the valve C and allows the air to enter, when the water will quickly flow from the receptacle and the downward movement thereof will cease, the spring B serving to raise the cup or receptacle to its normal position.

In Figs. 1 and 2 I employ two valves instead of the one referred to with relation to Figs. 3 and 4, the construction of which valves has already been described. The valve H (seen in Fig. 2) remains normally seated, while the valve K remains unseated until such time or times as the mechanism is manipulated to flush the water-closet-, at which time the valve H will be unseated and the valve K seated, thus allowing the fluid which has been contained in the chamber P to flow into the tank, commingle with the water therein, and thus disinfect the closet.

The cup or receptacle 0 is arranged in Fig. 1 in reverse position to that described with relation toFig. 3, and the lower end of the rod X is secured thereto, while the upper end of said rod passes through aguide Y and thence into the sleeve T, wherein it is held by means of a set-screw Z. The upperend of the sleeve T passes through a guide \V, as already described,and a collar Uis arranged upon said sleeve and is adjustable thereon in both cases through the medium of the set-screw V, so as to limit the downward movement of the cup or receptacle 0.

The spring B" is arranged, as already described, so that it can be readily adjusted, and consequently afford a greater or less resistance to the downward movement of the cup in order that the output of disinfectant fluid may be properly regulated.

The flap-valve C is dispensed with, and the cup 0 is provided with a series of perforations D', said cup becoming full of water as the tank B itself becomes filled,eitherthrough said perforations or over the sides of the cup, so that when the mechanism is operated to flush the closet the water will first leave said tank B and then flow through the perforations D, after which the spring B will force the sleeve T upwardlyin the direction of the arrow seen inFig. 1, thus causing the valverod G to descend to seat the valve H and unseat the valve K, and so permit the discharge of the disinfectant fluid into the tank B, as above described, said tank being now substantially empty.

The perforations D referred to are of such character as to permit the water in the cup or receptacle 0 to empty more or less slowly to suit varying requirements and to enable the spring B to act to move the sleeve T upwardly more or less quickly, so that the valves H and K may be moved to cut off the flow of the disinfectant fluid at any predetermined time in order that unnecessary waste thereof may be avoided.

In the practical application of my invention the tank E is located so that the outlet in the casing N willbe directly in alinement with the pipe 0, although this is not absolutely essential, and instead of discharging the disinfectant fluid directly into the bowl of the closet or into the tank B itself I may employ a pipe (not shown) which will connect with the discharge end of the chamber P and lead directly into the pipe or conduit 0 or other desired point.

To regulate the amount of disinfectant to be discharged from the reservoir with relation to the amount of water used at each flushing of the closet, as constructed according to Fig. 3 of the drawings, it is only necessary to shorten the chain \V, so that more or less movement may be given to the cup or receptacle, it being apparent that by shortening the chain the sooner the water will leave the cup or receptacle and allow the spring B to close the valve, as before described, and vice versa. The desired regulation is effected by adjusting the rod X within the sleeve T so that the cup employed will rest at any predetermined or desired elevation, as the Weight of the water in the cup or receptacle will begin to lessen when the closet is being flushed and so remove the resistance to the spring more quickly, thus opening the valves and keeping them open until the tension of the spring overbalances the water in the cup and brings the cup or receptacle back again to its normal position.

The collar U is adjustably mounted upon the rod or sleeve T and is intended to limit the downward movement of said rod or sleeve, so that the valve H (shown in Fig. 2) by its intermediate connections maybe caused to rise to a greater or less extent to permit any required quantity of disinfectant to flow from the chamber P. The collar U may of course be entirely dispensed with and the fiowof the disinfectant be regulated in the manner hereinbefore described; but I have deemed it advisable to use said collar, as it; is evident its abutment against the guide W in the descent of the rod or sleeve will serve to remove all strain upon the valves and prevent them from leaving their seats through the resiliency of the spring B.

It will be evident that, if desired, I may employ a plurality of valved outlets from the tank E, according to requirements.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
