IMPROVEMENT IN DISINFECTING APPARATUS FOR WATER-CLOSETS, 6c.

Specification forming/parilwetters Patent No. 222,519, dated December 9, 1879 5 application filed October 22, 1879.

To all whom it maj/fc/oncm.:

` Be it known that I, EDWARD J MALLETT, Jr., of the city, county, and Sta-te of New York, have invented a new and useful Improvement in Disinfecting Apparatus for Water-Closets, dto., which improvement is fully set forth in the following specification, reference being had to the accompanying drawings,

one appertaining to what I call the liquid disinfector, and the other to the aerial disinfector. Through the side of the vessel A extend two pipes, c d, one above the other, and in applying my apparatus to a closet the upper pipe, c, is connected with a water-service pipe,

or with-a tank, as the .case may be, and otherwise so arranged that water constantly drips into the vessel A through this pipe, or, in other Y of said pipes.

words, so that a continuous supply of water is maintained. The other or lowerp'ipe, d, at the saine time is connected to the bowl K of the closet, orto the water-supply pipe or the soilpipe, so aste dischargeinto the bowl or either The vessel Aisthen lled with disinfecting material, such as chloride of Zinc,

" and as the water drips into the vessel from the supply-pipe c,it is'charged with or becomes a` solution of such material.` When the liquid disinfectant thus formed reaches the level of the pipe d,itloverflows by means of this pipe, and is thereby conducted to the closet bowl or pipe. In this manner the closet is constantly iiushed with a disinfectant, which prevents the local manufacture of gases and stamps out any gases that attempt to enterfrom the sewer.

2 let.

Into the vessel B project two pipes, f g, one forming an air-inlet, and the other an air-out Said vessel B is, supplied with a disinfectant, such as a solution of thymol, and the arrangement of its two pipes is such that the air-inlet f terminates below the level of the solution, while the mouth l of the air-outlet g is above such level.

To the vessel B is connected an air suction and forcing device, consisting, in this example, ofA a exible cap, H, which is attached to the top of the vessel and carries a weight, i, and of a chain, j, or the like, for lifting the cap up against the action of its weight. When the cap H is lifted up a vacuum is formed in the vessel B, which is at once iilled with air admitted by the inlet f, and since this incoming air is caused to pass or bubble up through the thymol or other solution it becomes charged with its vapor. If the cap H is now released, the same sinks down with the weight fi, and by this means the air, charged or impregnated with the vapor of thymol or other material, is expelled from the vessel B, by the outlet g, into th'e closet-room, the effect ot' which is to maintain thereilran .atmosphere inimical to the propagation of disease-germs, a-nd free from unpleasant odors.

The direction of the pipe f, forming the airinlet, is downward and inward, and since it terminates below the level of the solution in the vessel B it always contains a column of liquid, which acts as a valve in preventing the escape of the air through the inlet while it is being forced out by the outlet g. In order to prevent the influx of air through the pipe forming the outlet g, this pipe is made of smaller diameter than the inlet-pipe f; but this can also be accomplished by providing the outlet with a self-acting valve. The air inlet and outlet j' g, moreover, may be formed by valvecovered openings in the top of the cap H, and in that case a sponge or other absorbent may be attached to the cap in such a manner as to dip into the solution in the vessel B and give it oft' as a vapor, thereby charging the incoming air. The two vessels A B are connected together, the same being in this example arranged one within the other, so that they occupy the least possible space, and they are sur mounted by a cover, N, which is suitably shaped to allow the motion of the cap H, and which has a slot, o, for the passage of the chain j, or a lever for operating the chain.

When my invention is applied to a closet having a hinged seat-cover, as at L, Fig. 2, the

chain j is connected to this cover in such a manner that when the seat-cover is lowered, as after using the closet, the cap H is lifted to its upper position, audit-ice versa. The result of this arrangementis; tliat the operation of the cap II is automatic, and the vapor is expelled from the vessel B during the use of the closet. The chain j, however, may also be connected with the door of the closet, or arranged to be operated in any other Way.

It is obvious that my invention is applicable to urinals, sinks, and other similar places, as Well as to water-closets, and when it is applied to a urinal the cap H may be operated by a hinged platform arranged to receive the weight of the person using the urinal.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a watercloset or the like, of an aerial disinfector consisting of a vessel for holding the disinfecting material, an air-inlet and an air-outlet to such vessel,

and an air suction and forcing device attached thereto, all adapted for use substantially as described.

2. The combination, with a water-closet or the like, of a liquid disinfector connecting with the bowl or other appropriate part of the closet= and an aerial disinfector communicating with the closet-room, substantially as and for the purpose described.

3. The combination, with the vessels A B, o a water-supply pipe, c, and a discharge-pipe, d, an air-inlet, f, an air-outlet, g, and anair suction and forcing device connecting with the vessel B, all adapted for use substantially as described.

In testimony that I claim the foregoing 1 have hereunto set my hand and seal this 20th day of October, 1879.
