Aug. 29, 1939. J. BUXTON RUBBER FAUCET EXTENSION Filed Dec. 19, 1938 Patented Aug. 29, 1939 UNITED" STATES PATENT OFFICE Jay Buxton, Hawthorne, Calif.

Application December 19, 1938, Serial No. 246,534

2 Claims.

My invention resides in a resilient faucet extension particularly adapted for use in kitchen sinks, or wash bowls, the extension having sufficient resiliency so that it may be bent up or down or sideways to project water on dishes or the like for washing and rinsing the same. Also, another feature of my invention is that the extension being resilient and preferably of somewhat soft rubber lessens the danger of breaking and cracking dishes as quite often occurs with the metal faucet extensions.

Considered in more detail an object and feature of my invention is in providing a metal swiveling elbow which may be attached preferably to a double faucet connection through which either hot or cold water or a mixture may be discharged and to this elbow is clamped or moulded or moulded over the entire exposed part of elbow, a rubber tubular extension, this hav- 20 ing a down turned nozzle for discharging water downwardly, the extension being sufficiently resilient so that it may be bent downwardly or have a nozzle twisted at an angle in order to project hot water on dishes or the like for rinsing and scalding such dishes. On account of resiliency the extension returns to its original and normal position. and shape.

Another detail feature of my invention is having the extension with tapering walls, such walls beng comparatively thick and preferably circular at the place of attachment to the metal elbow. The shape changes forming an oval with the long axis vertical and at the mouth of the nozzle the discharge orifice is preferably oval or in the form of a narrow opening with parallel sides and rounded ends, this orifice being horizontal. The object of the oval section being to strengthen against water pressure but leaving it flexible sideways, but of course may be circular. Another feature of my invention is the employment of a web on the underside of the device adjacent the nozzle part, which not only forms a stiffener, but facilitates gripping the extension to twist the nozzle end in one direction or the other. By having the nozzle of thin rubber, the orifice may be contracted by squeezing the nozzle with the fingers and thus give a forcible jet of water for rising dishes or vegetables, or the sink or bowl itself, as the case may be. 4

My invention is illustrated in connection with the accompanying drawing in which Figure 1 is a side elevation of my invention partly broken away to illustrate the connection to a water faucet.

Figure 2 is a longitudinal section t aken on the line 2-2 of Figure 3 in the direction of the arrows.

Figure 3 is an underside view taken in the direction of the arrow 3 of Figure 2.

Figure 4 is a transverse section on the line 4-4 of Figure 2.

Figure 51s a. transverse section on the line 5-5 of Figure 2.

Figure 6 is a transverse section on the line 66 of Figure 2.

In my invention I employ a swivel elbow II, this has a rim l2 and is secured to the threaded end l3 of a water faucet M by means of the clamping nut Hi, there being a Washer to prevent leakage. The elbow is preferably cylindrical on its outside surface and of an inside cross section area equalling that of the faucet. The end of the elbow is provided with a series of shouldered projections it.

The rubber extension designated has a thick inner end 2| which is cylindrical on both its inside and outside surface indicated at 22 and 23. The walls 24 being comparatively thick, this end fits over the shouldered projections l6 and is fitted over the elbow as indicated at 24' and secured by clamps 25 which may be of any suitable type. Towards the outer end the walls taper and the shape is changed to form at ap- I proximately section 55 a structure with both the inside and outside surfaces 26 and 21. being oval and the wall section 28 being quite thin.

The nozzle portion 30 turns downwardly and is flattened on the sides having parallel inside and outside surfaces ill and 32 connected by the rounded ends 33. The wall section 34 is also quite thin, thus forming a narrow orifice 35, the lower edge 36 of the extension at the nozzle being horizontal.

-A rubber web 31 is formed integral with the extension and located on the underside at the curve formed between the main portion and the down turned nozzle. This web stifiens the portion at the nozzle against bending upwardly, but does not prevent the nozzle being bent downwardly, the web also facilitates grasping the 1102- zle portion for turning this to one side or other with the swivel elbow or twisting the extension on its long axis. On account of the side walls adjacent the orifice being vertical and parallel and also quite thin in thickness, a person may readily grasp the nozzle portion between the thumb and first finger and thus still further narrow the orifice in order to discharge water with a forcible jet which may be sprayed on dishes or vegetables.

The web 31 also functions to resist the discharge reaction oi! the water jet at the orifice which would tend on account of the nozzle section being comparatively thin, to straighten the nozzle somewhat in alignment with the main portion of the extension, but the web retains the nozzle portion in its downturned curve. On account of the rubber walls 01 the extension thickening towards the point of attachment to the elbow, the device is inherently sufllciently stiff to retain itsshape and position in the normal discharge of water. This rubber extension on the faucet may be turned in a partial circle on the swivel formed by the rim l2 and the clamping nut I5.' Manifestly in addition on account of the resilient nature of the tubular rubber extension, the nozzle may be depressed or raised or twisted if desired.

Various changes may be made in the details of the construction without departing from the spirit or scope of the invention as defined by the appended claims.

having a downwardly curved nozzle with an oriflee, the walls tapering towards the orifice and adjacent the orifice, the vertical side walls being substantially flat whereby a narrow orifice is formed, the walls adjacent the orifice being sufliciently flexible to be pressed inwardly by hand .to contract the opening at the orifice.

2. As described in claim 1, the cross sectional shape of the main part of the horizontal portion of the extension changing from a circular to an oval shape with the long axis of the oval vertical and a web connecting the underside of thehorizontal part of the extension and the inside of the curve at the nozzle, the web terminating adjacent the orifice.
