To all whom it may concern:
Beit known that I, L zen of the United States of America, and
lumbia, have invented certain new and useful Improvements in and Relating to Apparatus for Applying Liquids, of which the following is a specification.
This invention relates to improvements in devices for discharging liquids such as for toilet, medical, or other treatment of the human body; and the objects and nature of my invention will be readily understood by those skilled in the art in the light of the following explanations of the accompanying drawings illustrating what I now believe to be the preferred mechanical expression or embodiment of my invention from among other forms, constructions and arrangements within the spirit and scope thereof.
An object of the invention is to provide means whereby the pressure of municipal and other water supply systems can be conveniently utilized as the power forexpelling liquids for various purposes from con tainers that maintain such liquids from communication with and from dilution by the power-supplying water.
With this and other objects in view my invention consists in certain novel features of construction and in combinations and arrangements as more fully and particularly set forth and specified hereinafter.
The accompanying drawings show an embodinient of my invention, in longitudinal section, for purposes of explanation but without thereby intending to limit the in vention to this particular embodiment.
In the drawings I show a water supply pipe 1 connected with any suitable supply ofwater (or other fluid) under pressure. This pipe is provided with any suitable cut-oil valve controlled by handle 2, whereby the pipe can be opened to flow of fluid, and can be closed to stop the flow of fluid, to any suitable pressure tank or chamber 3, in which is arranged any suitable flexible wall or otherwise compressible liquid container 4 having a valve controlled outlet to a flexible or other suitable tube 5, terminating in anysuitable discharge nozzle 6.
In the particular example illustrated, I show a vertical metal tank 3 adapted to be secured at any suitable or convenient location, in a bath or toilet room for instance. If so desired, the tank can have exterior supporting brackets or arms such as 3', to SIMMONS, a c1t1-f fit the wall or any other support, and receive secur-ng screws or other suitable fastenmgs. In this instance, the water supply "pipe 1 depends from the tank bottom and extends therethrough, and is intended to be coupled to and receive its water supply from any convenient house water pipe, such as any pipe in a bath room that contains water under pressure. As the tank 3 is comparatively small, it can be arranged with the various valves within convenient reach and yet so as to be out of the way and not interfere with the free use of'the lavatory, and
also to permit the lavatory to catch and carry oil water drained from the tank through drainage pet cock or other suitable valve 3*. Such drainage device is shown in the form of a normally-closed pet cock 3 depending from the tank bottom to discharge the water from the tank (when the stop cock in pipe 1 is closed) after a liquid expelling operation. Any suitable compressible container for the liquid to be expelled, is exposed to the water pressure in the closed substantially liquid tight tank 3.
As an example of one among other liquid containers that can be employed, 1- show a liquid tight flexible bag, such as an impervious flexible rubber bag 4, depending in the tank, and of small size or capacity with respect to the internal dimensions or capacity of the pressure water tank 3. The container 4 shown is a one-piece rubber bag at its upper end'having an elastic contracted bag supporting mouth or neck 4 by which'the bag is suspended in the tank. The bag is supported by and suspended from the tank top or closure which embodies an exterior removable cap or plug 7 closing the contracted'mouth 3 of the tank, and gasket 8 normally compressed between the bottom face of the cap and the top edge'of the tank mouth 3 to provide a liquid tight closure for the. tank. The cap is released and clamped in sealing position, by any suitable means, although I show a wing or other hand nut 19 for this purpose, removably overlapping the cap and screwing on the exterior screw thread 3 of the tank mouth, as will be readily understood by those skilled in the art.
The cap is formed with a liquid duct 7 extending longitudinally therethrough and till ill?) open at its lower end into the liquid bag a and at its upper end into vertical rigid means, although I show a valve in the uptubci section 9. The cap 7 is, in this example, formed with a reduced coupling nip le 7 depending in the tank, and annular y en larged exteriorly at its lower end, to extenorly and longitudinally receive the contracted mouth 4' of the bag 4 and form a liquid tight joint therewith. The elastic mouth of the bag is expanded and forced 'onto the coupling nipple 'so as to maintain its position thereon under tension. The bag can thus be readily removed and a new bag a plied, by removing the nut 19-and lifting tl ie cap carrying the bag from the tank. The parts can'be as easily reassembled in operative positions.
The upper end of the bore or duct 7 is usually enlarged and screw threaded and the stiff or rigid tube 9 is screwed thereinto to provide a liquid tight joint between cap and tube. a
The tube 9 forms a part of the liquid discharge or delivery piping which can be of any suitable construction to deliver the expelled liquid at any suitable point and in any desired form or manner. In the particular example shown, the upstanding rigid tube section is provided at its upper end with coupling head 9' entering and forming a liquid tight joint with rubber or other flexible tubing 5 of any desirable length, and the free end of this flex ible tubing carries a stiff tube length 11 that terminates in any suitable spray nozzle 6.
The stifi section 11 can be used as a handle in manipulating the tube and nozzle to spray the body with any desired liquid expelled from the bag 4, or to subject any part of the body, or other object, to any suitable or desired liquid supplied to the bag '4.
The flow of liquid from the collapsible container 4 can be controlled and cut oil in any suitable manner or by any suitable standing tube section 9 for this purpose, said valve having an exposed accessible operating handle 10.
Any suitable provision can be made for introducing the antiseptic, toilet, medicinal, perfume or other liquid into the container 4. Of course, the liquid can be introduced by removing the tank cap and separating the container therefrom and filling the container through its open mouth, or without disturbing the cap from its condition sealing the tank, the pipe section 9 can be unscrewed from the cap and the liquid introduced through duct 7. However, I prefer to provide means for filling the container 4 without disturbing the cap and piping,
and hence show a filling cup or funnel 12 supported by a branch or filling tube 13 joined to and opening into the tube 9 so that the liquid can drain by gravity from the cup 12 through branch tube 13 into tube 9 and from thence into container 4. The
branch tube 13 is provided with a normally closed out off valve having exterior operating handle 14. During the filling operation, the valve of handle 10 is 0 en to permit outflow of air as the liqui drains into the container, and the valve of handle 2 is closed and the water has been drained from tank 3, the pet cock being then usually open. After the filling operation, the pet cock and the valves of handles 10, 14, are closed. The pressure water controlling valve of handle 2, can then be opened, to permit flow of water under pressure into the closed pressure tank 3 to establish the desired pressure in said tank, and the consequent compressing action on the container 4.
By manipulating the valve handle 10 the operator can start, stop and control the flow of the expelled liquid from nozzle 6 while the handle section 11 is manipulated to direct the li uid spray where desired. A single chargeo liquid in the container 4,will ordinarily supply a large number of spray applications and last for a considerable length of time as the ordinary flow through nozzle 6 as to volume is exceedingly slow, and furthermore can be controlled as de sired by the valve of handle 10. The water pressure in the tank 3 is maintained by leaving the pressure water cutoff valve open, although if preferredthe valve of handle 2 can be closed after each liquid expelling operation. The apparatus can beultilized for spraying or otherwise applying any suitable liquid to the human body or any other body or object for any desirable purose.
p It is evident that'various changes, modifications and variations might be resorted to without departing from the spirit and scope of my invention and hence I do not wish to limit my invention to the exact disclosures hereof.
