SPRAY Filed Oct. 51,. 1953 INVENTOR Ml BY 7 mwzwet ATTORNEY Patented Jan. 22, 1935 UNITED STATES PATENT, OFFICE" SPRAY Albert H. Levene, Philadelphia, Pa. Application October 31, 1933, Serial No. 695,984.

5 Claims. (01. 299-58) v The object of my invention is to devise a novel spray mechanism, which although not limited to such use, is especially adapted for use with vegetables and fruit which are being commercially displayed in order to create a mist like spray which will settle on the goods and retain them in a fresh and saleable condition.

A further object of this invention is to devise a novel spray head wherein a novel construction of an adjustable deflector is employed to vary the throw of thespray, and provided with a support of such a character that the action of the spray will attract the attention of intending purchasers of the goods which are being displayed.

A further object of the invention is to devise a novel spray nozzle which also acts as a seal, and a novel construction and arrangement of drainage devices.

With the above and other novel features in view, as will hereinafter more clearly appear, my invention comprehends a novel spray.

It further comprehends a spray having a spray nozzle and screen and a construction and arrangement of an adjustable deflector.

It further comprehends means for draining the excess water.

Other novel features of construction and advantage will hereinafter more clearly appear in the detailed description and the appended claims.

For the purpose of illustrating the invention, have shown in the accompanying drawing a typical embodiment of it, which, in practice, will give satisfactory and reliable results. It is, however, to be understood that the various instrurnentalities of which my invention consists can be variously arranged and organized, and my invention is not limited to the exact arrangement and organization of these instrumentalities as herein set forth.

Figure 1 is a side elevation of a spray embodying my invention.

Figure 2 is a side elevation, partly in section,

on an enlarged scale.

Fi ure 3 is a bottom plan view of a deflector.

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

Figure 5 is a top plan view of a fitting employed.

Similar numerals indicate corresponding parts.

Referring to the drawing:

A fitting 2 which is internally threaded at its lower end as at 3 is adapted to receive a water pipe 4 and is externally threaded as at 5 to receive a clamping nut 6 so that it can be secured to the bottom of a pan 7 having an opening to receive it and against which the flange 8 of the fitting engages. The fitting is internally threaded at its upper end as at 9 to receive the threaded lower end of a fitting 10. forming the base'of'the spray mechanism. This fitting 10 is internally threaded at its upper end asjat ll to receive the lower threaded end of the water pipe 12, the upper end of which is in threaded engagement with a drainage cup 13. The water pipe 12 is surroundedzby an outer pipe 14 which is spaced from it to form a drainage channel 15. The base 10 has upwardly extending circumferentially spaced fingers 16, see Figures 1, 2 and 5 to receive the lower end of the outer pipe 14 which rests upon the circumferentially spaced lugs or bosses 17, thereby providing drainage ports 18 from the drainage channel 15 and eliminating :ie'necessi'ty of forming holes in the pipe14. The upper end of the outer pipe has a close fit in the recessed hub of the drainage cup 13. The drainage cup'has a desired number of drainage holes 19. f

The inner pipe 12 at its upper end is provided with a strainer 20 having the lower end closed by an imperforate disc 21, and its upper end'has a disc 22 which seats on the upper end of the pipe 12 and is provided with an aperture 23. r

24 designates a spray or atomizing nozzle which is internally threaded to engage the externally threaded end of the pipe 12, and provided with a shoulder 25 which engages the disc22' to form a water tight seal. A sealing washer may be employed if desired between the shoulder 25 and the disc 22.

The spray nozzle 24 has a straight bore 26 which merges into a conical portion 27 which leads to the port 28. The nozzle has a polygonal contour at its outer periphery to facilitate its manipulation, and preferably tapers towards its outer end. i

The inner pipe 12 extends above the drainage cup and is threaded to receive an adjustable spray cage. This spray cage has a base 29 in the form of a casting having a hub and threaded to engage the pipe 12 and provided with circumferentially spaced, outwardly extending arms 30 which are apertured to receive the reduced ends of spacing rods 31.

The upper ends of the spacing rods 31 are reduced and secured in apertures in a spray head or deflector 32 provided with a knob 33, forming a grasping handle.

A look nut 34 on the pipe 12 looks the spray cage in the position to which it has been adjusted but this nut may be dispensed with as desired.

The bottom face of the spray head 32 is preferably flat as is seen in Figure 3.

The base 10 may have opposite sides flattened as at 34 to adapt it to receive a wrench.

The spray mechanism is secured to a water pipe and a pan or container as already explained. When the water is turned on, it passes through the pipe 12, the strainer 20 and spray nozzle 24 and impinges against the spray head 32 and is deflected laterally in the form of a mist or vapor. The throw of the spray may be varied by rotating the sprayoage to vary the distance between the spray nozzle and the spray head.

My present invention is especially adapted for use with fruit and vegetable display counters so that a mist or vapor will fall like dew on the fruits and vegetables, when desired, to retain them in a fresh and crisp condition, so that they will present an attractive andinviting appearance to the purchasing public.

The spray head forms an atomizing baffle having one or more members connecting it with its base so that the action of the water is readily visible. l

A reinforcing member 34 may be employed for securing the fitting 2 to the bottom of the pan and as illustrated it is in the form of a channel fixed in position in any desired manner as by welding, riveting or soldering.

It will now be apparent that I have devised a new and useful spray which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof, which will give in practice satisfactory and reliable results, it is to be understood that this embodiment is susceptible of modiflcation in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:-

l. The combination of a water inlet pipe having a discharge opening, a' drainage cup secured to said water inlet pipe, a drainage pipe secured to said drainage cup and receiving drainage therefrom and surrounding the water inlet pipe, and an atomizing deflector receiving impact of water from said water inlet pipe, said deflector being supported on said inlet pipe independently of said drainage cup.

2. The combination of a water inlet pipe, provided with screw threads at its upper end, a drainage cup through which said pipe passes, said cup being secured to said inlet pipe, a pipe surrounding said inlet pipe, secured to said drainage cup, and receiving drainage from said cup, and an atomizing deflector having a base longitudinally adjustable on said inlet pipe by means of screw threads, and having a surface spaced from the base to receive impact of water from said water inlet pipe.

3. The combination of a water inlet pipe, provided with screw threads at its upper end, a drainage cup thru which said pipe passes, said cup being secured to said inlet pipe, a pipe surrounding said inlet pipe, secured to said drainage cup and receiving drainage from said cup, and an atomizing deflector having a base longitudinally adjustable on said inlet pipe, by means of said screw threads, and supported on said inlet pipe independently of said drainage cup and having a surface spaced from the base to receive impact of water from said water inlet pipe.

4.
