- Specification of Letters Patent.
Patented Nov. 11, 1913.
To'all whom t may concern:
NAUDE, a citizen of the United States, resid'- ing at Haverhill, in the county of Essex and State of Massachusetts, have -invented an Improvement in Water-Coolers, of which the following is a specification.
This invention relates to that class of Water-coolers in which a sealing and cooling receptacle, or container, is provided Within the body of the cooler, into which water is discharged from an inverted bottle supported thereover, as the water is drawn from the receptacle. 0 ter, so far as I am aware, the air which must enter the bottle and ass through the water In prior devices of this charactherein, to permit t e water to flow down,
into the sealing container, is taken directlyv into the container through its top opening, so that dust and otherimpurities, which may be carried by the air, are likely ,to be i taken up by the Water in the bottle'as the air passes up throughgit. As the airusually passes beneath the cover into the cooling chamber, it comes in contact with the ice therein, so that germs or impurities which may be liberated on the melting of the iceare also likely to be taken up by the air, which later passes up through the waterin thebottle. 4
The primary object of my invention is.' to
provide a form of watercooler of the above described type, in which the entrance of air, containing germs or impurities, into the sealing tank, and the subsequent assage thereof through the water in the bott-le, is preventeds o that a completely sanit-ary'cooler1 .of the abovevtype is produced. I accomplish this object by the means shown in the accoml panying drawing, inwhich,
Figure l is a central verticalsectional view of a water-cooler provided with my invention. Figs. 2 and 3 are det-ailviews in plan and side elevation, respectively, of the coupling for providing a ti ht connection between the bottle and sealing receptacle,
which I employ. Fig. 4 is a detail sectionalview of the air filter, and Fig. 5 is a detail view Showing a modified arrangement of air inlet.
As shown in the drawing, an ice receptacle, or tank a, of usual form, is'provided, said tank having a cover b, provided with a side opening 7)', through which the ice is passed to fill the tank, and a central bottle- Be it known that I, WILLIAM E. PA'I'-,
receiving opening b2.
, A water container c, is arranged within tion with the walls of the neck. An air' filter d is provided in the end of said pipe d, and may consist of a layer of absorbent cotton d2, or some similar antiseptic material, arranged between screens of fine wire gauze d, although any form of filter which will purify,'or make antiseptic the air passing therethrough, may be employed. Means whereby the filter Amay be conveniently renewed are preferably provided.
A closure e, preferably of elastic rubber, is provided, said cover having an integral elastic fiange e at its edge, which is adapted to be sprung over the fiared end of the neck 0'.of the container, to make a tight connection therewith. Said closure is provided with a central aperture e, which is surrounded by 'an integral, annular, elastic l lip e", depending from the under side of the closure, and a sealing tube f is arranged within the neck c', in register with said aperture, and has a flanged upper end Which is inclosed by said lip e3 to make a tight connection therewith. Said tube f is adapted to extend slightly below the normal Water level in the container, and a free passage of air is provided from tube d to the 'surface of the water about said tube f. Said closure is also provided with a combined funnel and coupling e4,- which is integrally connected ithereto at its upper side and surrounds the aperture e2 therethrough, the upper portion thereof 'extending through the aperture b2.
in the cover b, and having a` turned-over elastic lip e5 at its upper edge, which engages the upwardly extending fianged edge surrounding said opening b2.
The bott-le g is of usual form and is provided With a neck g having a conical-shaped end portion g2, which is adapted to be forced into the lower end portion of the funnel e4, so as to make an air-tight connection therewith, the elasticity of the funnel permitting it to yield to some extent as shown in Fig. 1. The parts are so formed with reference to the shapeof the bottle that the top portion of the bottle will, at the same time, rest on the edge of the rubber covered lip b3, which forms a cushion therefor. f
The container c is provided with the usual outlet pipe which is connected to the container c, and extends through the wall of the tank a, terminating in a faucet i.
In operation the neck of the bottle is placed 1n the funnel portion e4 of the cl'osure, so that the water flows therefrom into the container until the lower end of the sealing tube f is submerged, preventing the further passage of air into the bottle. During this operation, and when water is drawn from the container, the air which is drawn into the container to permit the displaceyment of the water therein, will be drawn beneath the cover into the ice-chamber and thence through the air filter d and pipe d, the entrance of air to the container or bottle, in any other manner, being prevented. It will be apparent, therefore, that, with the apparatus above described, all the air which comes in contact with the water from the bottle may be previously purified and made antiseptic.
In'Fig. 5 I show a modified arrangement of the air-inlet pipe, in which the air-inlet pipedO is extended upwardly through an aperture in the cover b, so that, instead of taking the air from within the tank, it is taken entirely from outside the tank. For some reasons this arrangement is preferable, as it is believed to be more economical of ice than in the previously described arrangement, for the reason that the warm air from the room is nat carried through the ice chamber in such a way as to be cooled to such an extent, as with the other arrangement.
I claim 1. A water cooler comprising an ice receptaele having a cover provided with an opening, a water container arranged in said receptacle and having a top opening, a tubular receiver for the neck of a bottle arranged to connect said openings and having a seat therein to receive the end portion of the bottle neck to make a tight connection therewith, a sealing tube having a tight connection with said seat and depending into said container, and means to admit air to the container about said sealing tube, substantially as described.
2. A water-cooler comprising a Water container having a top openinga closure for said opening having an aperture therethrough, a sealing tube connected to said closure and depending into the container, an upwardly extending funnel havin a tight connection with said closure and adapted to receive the neck of an inverted bottle, to make a tight connection therewith, and n means to admit air to the container above the lower end of said tube, substantially as described.
3. A Water-cooler comprising a water container having a top opening, a closure for said opening having an aperture therethrough, a funnel of elastic material having a tight connection with said aperture, a sealing tube having a tight connection with the aperture of said closure and depending into said container, an inverted bottle having its neck seated in said funnel, and means to admit air to the container about said tube, substantially as described.
4. A water-cooler comprising an ice-receptacle having a cover provided with a central opening, a water container arranged in said receptacle and having a top opening, a closure forsaid opening having an aperture therethrough, a funnel of elastic material having a tight connection with said aperture and extending through the opening of said cover and supported by the sides thereof, a sealing tube having a tight connection with the aperture of said closure and depending into said container, an inverted bottle hav- Ving its neck seated in said funnel and resting against the sides of the cover opening,
`and means to admit air to the container about the sealing tube, substantially as described.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.V
