3 Claims.

My invention relates to a hot and cold water mixing attachment, and has for its purpose to provide a device that can be quickly positioned in operative relation to a pair of separate hot and cold water faucets so as to enable drawing a mixed supply of water from one outlet and thereby attaining any desired temperature.

A further object of the invention is to provide a practical structure that is economical to produce and can be applied to the hot and cold water faucets of conventional basins without the need of special tools or equipment.

Another purpose of the improvement is to provide an attachment that can be temporarily secured and quickly removed when desired, also one which is applicable to differenttypes of faucets and adjustable to accommodate varying conditions, as where faucets are arranged at varying distances from each other.

To these and other ends, the invention comprises the construction and arrangement of parts that will appear clearly from the following description when read in conjunction with the accompanying drawing, the novel features being pointed out in the claims following the specification.

In the drawing:

Fig. 1 is a perspective view illustrative of a preferred embodiment of the invention and showing it in operative position;

Fig. 2 is a front elevation of the attachment removed from the basin faucets.

Fig. 3 is an enlarged side elevation, partially in section, showing the means by which each elbow is held in operative relation to its faucet;

Fig. 4 is a side elevation of one of the elbows and its connection to the union, and

Fig. 5 is a detail sectional view on line 5-5 of Fig. 2.

Referring more particularly to the drawing in which like reference characters refer to the same parts throughout the several views, 1 designates a conventional basin and'2 are the hot and cold water faucets having spouts 3 to which the attachment is secured.

The invention, may be practically applied in a variety of ways, and in one preferred embodiment, as herein disclosed, includes a hollow union 4' having an outlet spout 5 that may be threaded on the upper end of the union 4, while 6 designates inlet branches or pipes preferably formed integral with the hollow coupling 4 and extending downwardly and forwardly at an angle to each other as shown.

Each of the hollow pipes 6 is adapted to receive a conductor or pipe '7 which has secured to its outer-end an elbow 8 preferably threaded thereon, the latter terminating in an enlarged coupling 9 adapted to surround the outer end of the spout 3, as shown in-Fig. 3. 10 designates a washer seated in the coupling 9 and engaging the outer endof the spout 3.

The elbow 8 and coupling 9 are held removably in operative engagement with the spout 3 by any suitable device such for instance as the bifurcated clamp 11, the arms of which engage around the elbow 8 on opposite sides thereof'and under the shoulder formed by coupling 9, as shown in Fig. 3. The clamping member 11 is pivoted in one of the openings 12 to a strap 13 that surrounds the horizontal portion of the spout. 15 designates a'tightening screw threaded in the arm 16 at the rear end of the clamping member 11 and adapted when turned to engage the lower side of the spout 3 and to force the arm 16 downwardly while at the same time projectin the bifurcated clamping member 11 upwardly and holding the coupling in tight engagement with the spout 3. 17 designates a knurled disk secured permanently to screw 15 for permitting ready adjustment of the latter.

Each pipe or conductor 7 leading from the elbow 8 is slidably or telescopically engaged in the branch or pipe 6 and held in adjusted position by means of a nut 21, see Fig. 5, having a knurled operating portion 22. The inner end of the nut 22 engages a metal washer 23 which in turn engages a rubber or fiber washer 24, compressing the latter when the nut is turned inwardly and thereby effecting a tight joint around the pipe 7.

By having the pipe '7 slidably adjustable in the branch 6, the device can be applied to any of the different conventional types of basins irrespective of the distance or angular relation between the two faucets. Where the latter are farther apart, the pipes '7 are not moved quite so far into the branches 6 of the union, and where the faucets are closer together, the pipes are telescoped farther into the branches 6. Then by tightening the nuts 21 and the clamping members 11, the device is held in operative relation and will continue to function as long as required. To remove the attachment, it is only necessary to release the clamping members 11, and the device can then be dropped downwardly away from the spouts 3. The entire structure an be quickly assembled in operative relation, nd affords a practical and efllcient device that equately takes the place of any combination faucet, at a minimum expense both of manufacture and assembly.

While the structure has been described with reference to a particular embodiment, it is not confined to the details t forth herein, and this application is intended cover any modifications or departures coming within the purposes of the improvement or the scope of the following I claim:

1. A universal hot and cold water mixing attachment, comprising a hollow union having an outlet connection, inlet branches integral with said union and inclining downwardly, forwardly and laterally therefrom, said inlet branches forming an obtuse angle with each other, conductors telescopically arranged in said inletbranches and adjustable endwise and rotatiyely therein, elbows fixed at the ends of said conductors having upwardly extending portions terminating in couplings, and means for securing said couplings to a pair of faucets.

2. A universal hot and cold water mixing attachment, comprising a hollow union having an upwardly and forwardly extending outlet, inlet branches integral with said union and inclining 1,osc,ass

downwardly, forwardly and laterally therefrom, said inlet branches forming an obtuse angle with each other, conductors adjustable endwise and rotatively in said inlet branches and extending downwardly in the same direction, elbows fixed at the ends of said conductors having upwardly extending portions terminating in couplings, and means for securing said couplings to a pair of faucets.

3. A universal hot and cold water mixing attachment, comprising a hollow union having an outlet connection, inlet branches inclining downwardly, forwardly and laterally from said union and formed integral therewith, said inlet branches forming an obtuse angle with each other, conductors telescopically arranged in said inlet branches and adJustable endwise and rotatively therein, elbows fixed at the ends of 'said conductors having upwardly extending portions terminating in couplings, each coupling including a shoulder, and clamping members removably positionable on a pair of faucets and engageable with said shoulders to hold the couplings thereon.
