DISINFECTING APPARATUS FCPR GLOSET CISTERNS.
SPECIFICATION forming part of Letters Patent No. 51,344, dated April 28, 1891.
Application filed November 6, 1890. Serial No. 370,532. (No model.)
To all whom it may concern:
Be it known that I, GEORGE TAYLOR,asubject of the Queen of Great Britain, residing in Liverpool, in the county of Lancaster, England, have invented certain new and useful Improvements in Apparatus for Automatically Supplying Disinfectant Liquids to ater-Closets, Urinals, and the Like, of which the following is a specification.
This invention relates to disinfectant-supply apparatus, and has for its object the sup ply of a small determinable quantity of disinfectant liquid to the flushingwater of waterclosets, urinals, or the like on each occasion that they are flushed. I accomplish this by providing a bottle or other suitable containing-vessel of special construction, to be hereinafter described, partially filled with disinfectant liquid, the remaining space containing air, and wholly or partially immersing the same in a cistern or tank, through which the water which flushes the water-closet, urinal, or the like passes, and in which the level of Water falls and rises each time the wateroloset or urinal is flushed. The action of the apparatus depends, as hereinafter set forth, upon variations in the volume and pressure of the said air in the containing-vessel consequent upon variation in the level of the water in the said cistern or tank.
In many cases water-closets and urinals are fitted with flushing-cisterns which just hold enough water to flush them each time they are used. When this is the case I make use of the rise and fall of the water-level in such flushing-cistern. and place the containing vessel therein.
In the accompanying drawings, which serve to illustrate my invention, Figure I shows in section one of the simplest forms of the containing-vessel. Fig. II shows the containing vessel in position in a flushing-cistern, the latter being shown in section conventionally; and Figs. III and IV are intended to illustrate diagrammatically the action of the apparatus.
Throughoutthe drawings similar parts are indicated by the same reference-figures.
The containing-vessel in its simplest form consists of a glass or earthenware bottle 1, completely closed, with the exception of the passage through the small-bore tube 2, which is fitted by means of a tight-fitting cork or stopper 3 in the neck of the bottle, the tube 2 being U-shaped, as shown. This containing vessel, when partially filled with disinfectant fluid, must be sufficiently heavy to prevent it from floating. \Vhen the containing-vessel, partially filled with disinfectant liquid, is immersed in water, as shown in Fig. III, the absolute pressure of the imprisoned airin the space 5 will be that of the atmosphere plus thatdue to the head of water h minus that due to the head of disinfectant (Z. If the water-level fails, it diminishes, the air expands, expelling a small volume of the disinfectant through the tube 2 until equilibrium is restored by the decrease in the pressure of the air consequent upon its expansion. It will be noted that the action ceases when the water-level falls below the outlet of the tube 2, as shown at c c in Fig. IV, where 6 indicates the expansion of the air and the fall of level of the disinfectant. If the water-level rises, the action will be reversed, h will increase, and a small volume of water will flow inward through the tube 2 and compress the air until equilibrium is again restored by the increasein the pressure of the air consequent upon its reduction in volume. \Vhen the water returns to its original level a a, the air returns to its original volume and pressure, and it will be seen that the volume of the disinfectant fluid previously expelled has been replaced by an equal volume of water which mingles with and dilutes the disinfectant in the container. The action will be repeated each time the water-level falls and rises, the disinfectant liquid in the container remaining practically constant in volume, but becoming gradually more diluted.
The volume delivered from the container for each fall of the water-levelis proportional to the volume of the air-space 5, and approximately proportional to the said fall.
In Fig. 11 the container is shown in position in aflushing-cistern, such as is commonly fitted to water-closets, urinals, and the like, the construction being such that the cistern is emptied each time that the closet is flushed. The container should be placed as far as possible from the discharge-valve and the tube 2 turned away from the latter, in order that the disinfectant may mingle chiefly with the IOO latter part of the [lush which seals the closet pan or trap.
I11 the case of water-closets and the like.
which are supplied directly from the main or from a large cistern, I provide a small auxiliary cistern, through which the whole or a portion of the flushing-water passes. I prefer generally to make this auxiliary cistern and its supply and discharge pipes as a pass-by to the main fiushing-pipe leading to the water-closet or the like. By making the supplypipe of this eisternlarger than the dischargepipe, or by carrying the latter, siphon-like, up within the cistern, the water-level in the auxiliary cistern will rise and fall each time the closet is flushed, and if the container be placed in the said cistern the action will be the same as already described.
As already noted, if the cistern should aecidentally be allowed to run dry there will be no flow of the disinfectant, such flow onlyoccurring while the water-level is above the outlet of the tube 2 and falling.
As already stated, the disinfectant becomes gradually diluted by the entry of water through the tube 2. \Vhere the disinfectant used is an aqueous solution, this dilution may be retarded by placing a supply of the solid disinfectant, in the form of powder or crystals, in the container. This will settle down to the lowest part of the eontainer, and in order to preclude the possibility of the tube 2 becoming choked thereby I prefer to keep the end of the said tube within the container above the level of such solid disinfectant, or to surround it by a tube or cap iinely perforated or made of wiregauze.
I find that although the action is similar when the tube 2 is made straight a small quantity of the disinfectant flows continuously if the latter is, as usual, denser than water, the disinfectant being displaced by the lighter water. This is objectionable, and in order to prevent it Iprefer to turn the outlet end up, as shown.
The internal diameter of the small-bore tube should only be sufficient to permit of the delivery of the full quantity of the disinfectant while the flush is occurring, and in some cases a tube of comparatively large bore constricted in places maybe substituted for the small-bore tube.
I do not limit myself to a bottle-shaped container, as I find it convenient in some cases to put the neck at the bottom of one side of the container, so that the latter can stand on its bottom in the cistern.
Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is
1. In eombination,the flushing-cistern containing the flushing-water. a vessel partially filled with disinfectant liquid with imprisoned air above the same to press thereon and having a small opening at its lower end, said vessel being held immersed in the water of the cistern to a depth sufficient to hold the disinfectant liquid under normal condition against the expellent pressure of the air by the pressure of the cistern-water, substantially as described.
2. In combination, the flushing-cistern containing the flushing-water and a vessel containing disinfectant liquid and im prisoned air above said liquid and held with its lower end below the normal level of the water and communicating with the interior of the cistern by a small-bore tube at its lower end, substantially as described.
3. In combination, the flushing-cistern containing the flushing-water and a vessel containing disinfectant liquid and air to press thereon, said vessel being immersed in the flushing-waterand held within the cistern and communicating with the cistern through a small-bore tube 2, which is bent upwardly, substantially as described.
I. A disinfectant device consisting of avessel having a small opening at its lower end and air-tight at its top, said vessel being partially filled with a disinfectant liquid and imprisoned air above the said liquid, substantially as described.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
GEORGE TAYLOR.
