No. 11,189 Claims priority, application Union of South Africa June 3, 1959 4 Claims. (Cl. 23925) This invention relates to a drinking fountain adaptor arranged for attachment to the spout of a water tap or faucet, to enable a person to drink water therefrom without the necessity of providing a cap, glass or other receptacle, or using a hand as a receptacle.
According to the invention, the device is a tubular fitting adapted, as regards its top end to be fitted snugly over the spout of a tap or faucet, and as regards the opposite end, arranged to be temporarily closed by a finger or by finger pressure so as to divert at least part of the flow of water passing through the device, through a jet passage communicating with the bore of the fitting. Preferably at least the top end, which is adapted to be fitted on to the spout of the tap or faucet, is made of rubber or other resilient material so that said end will be retained in position by a resilient constrictive gripping action. The said jet passage preferably extends in an upwardly and outwardly sloping angle so that a person using the device can conveniently place his open month over the issuing jet of water in the manner employed when using a drinking fountain.
Preferably the device is moulded from rubber or a suitable resilient plastic, with the lower outlet end being made sufliciently flexible to enable it to be substantially closed by a nipping action between a finger and a thumb. To facilitate this action, small bosses or restrictor buttons are moulded onto opposite sides of this end, and the wall thickness between these buttons is reduced to facilitate the closing operation.
The jet passage may be provided in a protruberance moulded onto one side of the device and can make communication with the bore thereof at a point inwardly from its lower end. To prevent water passing up the jet passage when water is flowing through the bore during normal use of the tap or faucet, a small deflecting lip is provided on the upstream side of the junction of the jet passage with the bore so as to create a slight injector effect. Such deflecting lip may extend wholly or partially round the bore so that it can serve as a base on which a screen may be rested within the device.
To enable the invention to be more clearly understood, reference is now made to the accompanying drawings which illustrate, by way of example, a preferred construction of the invention and a modification of such construction.
In the drawings:
FIGURE 1 is a front elevation of the device;
FIGURE 2 is a vertical sectional view taken on FIG- URE 1, on a plane parallel with the sheet;
FIGURE 3 is a side elevation;
FIGURE 4 is a vertical sectional view taken on FIG- URE 3 on a plane parallel with the sheet;
FIGURE 5 is an under plan view;
FIGURE 6 is a sectional view similar to FIGURE 4 but showing a modified internal construction, and
FIGURE 7 is the corresponding under plan view.
The device illustrated in FIGURES l to 5 is made of rubber to the external and internal configurations shown and is adapted as regards its top or socket end 1 to be a tight resilient fit on the spout of a tap (not shown). By nipping the sides of the bottom end together between finger and thumb by means of the restrictor buttons 2, a portion of the flow of water passing through the bore 3, will be diverted up the jet passage 4 which is provided at its junction with the bore 3, with a deflecting lip 5.
The modification introduced in FIGURES 6 and 7 consists in forming the deflector in several portions 5a around the base which portions provide a base for a screen, as aforementioned.
We claim:
1. A drinking fountain adaptor device comprising a tubular fitting having a bore therethrough one end of which is adapted to be fitted snugly over a spout of a water tap or faucet, and having an outlet opening in the opposite end which can be temporarily closed by finger pressure, said fitting further having an upwardly inclined jet passage communicating with the bore through which at least part of the flow of water passing through the device is directed when said outlet opening is closed, a small deflecting lip on said fitting projecting into said bore on the upstream side of the junction of the jet passage with the bore which is toward one end, whereby a slight injector eflect is created when said outlet opening is unclosed and water from the tap or faucet is flowing rapidly through said bore.
2. A drinking fountain adaptor device as claimed in claim 1, wherein the deflecting lip extends around substantially the entire inner periphery of said bore to serve as a support for a screen.
3. A drinking fountain adaptor device as claimed in claim 1, in which said tubular fitting has two small bosses molded on opposite sides of the outlet end, and the wall thickness of the tubular element extending between these bosses has a reduced thickness to facilitate the closing operation.
4. A drinking fountain adaptor device as claimed in claim 1, inwhich said tubular fitting is of a resilient and flexible material, whereby the outlet end is sufliciently flexible to enable it to be substantially closed by a nipping action between a finger and thumb.
