6 Claims.

The present invention relates generally to improvements in the art of dispensing liquids, and relates more particularly to improvements in the construction of spray heads.

Generally defined, an object of our present invention is the provision of an improved plumbing fixture which is simple in construction, neat and attractive in appearance, and highly efficient and practical in use.

10 As shown in co-pending application Serial No.

166,138, filed September 28, 1937, it has hereto- I fore been proposed to attach a'spray head to the end of a normally concealed hose for use in connection with kitchen sinks or the like; The spray head therein shown, however, is not of the most practical construction since it is highly desirable to provide a spray head of highly attractive appearance and conveniently accessible so as to permit disposition in a retaining socket 2o placed anywhereupon the sink without detracting therefrom and it is furthermore extremely desirable to provide a spray head which can be safely used with either hot or cold water.

It is therefore a more specific object of our invention to provide a spray head of neat and attractive appearance and which is adapted for use in connection with kitchen sink assemblages of the aforementioned type.

A further specific object'of our invention is to provide an insulated spray head which provides adequate protection to the user when hot water is passed therethrough.

A still further object of our present invention is to provide a spray head adapted to cooperate with a flexible conduit and with a sink and of such shape and construction as to be readily manipulated; Y

Still another specific object of the invention is to provide a spray head of durable construction which may be dropped or bumped against hard objects without danger of breaking the nozzle or other objects.

An additional specific object of the present invention is to provide a spray head which may be manufactured at moderate cost and which maybe readily installed and operated.

Th e and other specific objects and advantages ill be apparent from the following detailed decrlptio A clear onception of the several features coristituting our present improvement, and of the mode of constructing and of applying spray heads in accordancev with the invention, may be had by referring to the drawing accompanying and forming a part of this specification wherein the reference characters designate the same or similar parts in the various views.

Fig. 1 is a fragmentary part sectional front view of a sink showing the improved spray head in normal position as applied to a kitchen sink assemblage; I I

Fig. 2 is a transverse vertical section through the sink taken along the line 2-2 of Fig. 1 and showing the improved spray head in extended position;

' Fig. 3 is an enlarged fragmentary part sectional side elevation of the improved spray head as appliedto a portion ofthe sink; and

Fig. 4 is a transverse horizontal section through the assemblage taken along the line 4-4 of Fig. 3.

While the invention has been shown and described as being specifically embodied in a special type of sink assemblage, it is not the intent to thereby unnecessarily restrict the scope, since the features are more generally applicable to plumbing fixtures.

Referring to the drawing, the sink assemblage shown in Figs. 1 and 2, comprises in general a sink having a basin 5 provided with a drain 6, drain boards 1, 8 for dishes or other objects formed integral with the opposite ends of the basin, a rear ,wall 9 formed integral with the basin and HEISSUED' MAL 1. 3 194i drain boards, and an apron I0 also formed invalves l3, M respectively and an adjustable spout I I5 disposed between these valves l3, l4. Communicating with the lower portion of the spout I5 is a flexible hose or conduit it through which hot or cold water may be diverted by manipula tion of a diverter valve control II. This flexible hose I6 is confined beneath the sink and is concealed by the sink cabinet l8.

The present improved spray head 19, shown in detail in'Fig. 3, consists of a hose attachment plug or fitting 20. having a hose retaining knob 2|, a curved brass tube 22 secured at one end to the fitting 20 and having its opposite end provided with a spray nozzle 23. A rubber covering 24 provides a convenient gripping handle above the nozzle and is either pre-molded and slipped over the tube 22 and around the spray nozzle '23, or it may be molded directly upon these elements. and the end of the covering 24 tected against damage by a snug fitting sleeve 25 having a polygonal lower end. A tubular guide nut 26 having a polygonal hole is adapted to coact with the polygonal portion of the sleeve 25 to retain the spray head IS in any desired normal or inactive position, and is secured within a bore 21 in the elevated portion I I of the sink by means of a sleeve 28 coacting therewith, see Figs. 3 and 4.

The curved tube 22 may first be formed in the desired shape and size with one end thereof threaded or otherwise adapted to receive the hose fitting 20. The spray nozzle 23 of desired shape and size may then be threaded or otherwise attached to the tube 22 at the end remote from the threading and the rubber covering 24 may thereafter be applied to the tube 22 and nozzle 23.

The hose fitting 20 may then be attached to the threaded end of the tube 22 and the sleeve 25 may thereafter be attached thereto around the adjacent end of the covering 24, thus completing the spray head assemblage. A hole 21 may then be bored in any desired and conveniently accessible part of the elevated portion ll of the sink, but it is preferable to have this bore 21 to the left of the faucet l2 and near the drain board 8 as shown in Fig. 1 because in washing dishes, the dirty dishes are usually placed on the drain board I, are washed in the basin 5, and are then placed on the drain board 8 for rinsing .which may be conveniently done with the spray head and apparatus shown. The nut 26 may then be placed within the bore-21 and the sleeve 28 may be screwed or otherwise attached thereto from the lower side of the sink portion ll, thus firmly securing the nut 26 in position. The fiexible hose l6 which communicates with the diverter, may then be pulled through the hole in the nut 26 and may thereafter be forced over the knob 2| of the fitting 20 until it tightly embraces the fitting.

From the foregoing description it will be ap-' parent that the present invention provides a simple spray head which is extremely neat in appearance, durable in construction, and highly eillcient in use. The spray head may be formed in any desired shape or size and may be positioned on any desired portion of the sink without detracting therefrom. The rubber or similar covering provides a highly efficient insulating shield serving as a protection to the user against burning, and furthermore as a protec tion against possible chipping of the sink enamel and of dishes resting upon the sink. The improved spray head is moreover attractive in appearance; and by virtue of the polygonal or l square formation of the sleeve 25 and of the hole in the nut 26, the nozzle or head [9 may be set in various fixed positions whennot being handled. Obviously, instead of using rubber, other resilient material may be employed, and

the covering 2| provides an enlarged conveniently accessible gripping portion above the nozzle and thus facilitates safe manipulation of the nozzle. The diverter valve and control I! provide simple means for by-passing the flow either to the spout l8 or to the spray head I9 at the will of the operator. The improved spray head has proven highly successful in actual commercial use, and can be conveniently manufactured for sale at moderate cost.

nozzle at the opposite end, a rigid protective covering molded about said pipe and nozzle to form a gripping handle tliereover, and a sleeve embracing the hose attachment end of the covering.

2. A plumbing fixture comprising, a substantially U-shaped metal tube carrying a spray nozzle at one end thereof, a rigid insulated protective covering concealing the tube and nozzle and forming a protective handle thereover, a

hose connected to the opposite end of said tube, and a protective sleeve for said covering embracing said covering at said opposite tube end adjacent said hose.

3. In combination with a sink, a guide nut secured to the sink and having a polygonal hole,

and a substantially U-shaped rubber covered nozzle forming a protective gripping handle and having a polygonal protective end sleeve cooperable with said hole.

4. In combination with a sink, a guide nut secured to the sink and having a polygonal hole, and a substantially U-shaped rubber covered nozzle'forming a protective gripping handle and having a polygonal protective end sleeve cooperable with said hole, said nozzle sleeve being positionable in said hole in any of several positions.

5. In combination, a sink with a polygonal hole, a U-shaped nozzle having a downwardly directed spray head at one end and a polygonal opposite end, said opposite end being interchangeably insertible in said hole to place said spray head in any of several positions.

6. In combination, a sink having a guide nut provided with a polygonal hole secured thereto, a U-shaped nozzle having a downwardly directed spray head at one end and a downwardly directed polygonal protective end sleeve at the opposite end, said sleeve being interchangeably insertible in said nut to place said spray head in any of several positions.
