fiowes' Patented Apr. 20, 1937 UNITED STATES PATENT OFFICE Claims.

This invention relates generally to a humidifying and cooling apparatus and more particularly to a nozzle and bailie construction.

One of the main advantages of my construction 5 resides in the several adjustments embodied therein whereby the relationships between the baffle plate and the jet of water and the baffle plate and the produce or the like which is to be cooled may be altered so that an optimum of conditions prevail.

Briefly described, the above advantages are attained by mounting the impact of the bafile plate so as to be vertically adjustable and also utilizing the same construction for tilting the plate in either direction. Also, the cylindrical dome supporting the bafile plate is mounted for revoluble movement whereby the desired direction of the spray or vapor which issues from the baffle plate may be properly directed.

Another advantage resides in the detachable mounting of the bafile plate which permits the insertion of ones fingers into the top part of the cylindrical shell whereby cleaning or adjustment of my novel orifice member may be easily attained. Also, it is to be noted that the positioning of this orifice element is such that any leakage of water therearound is taken care of, the same trickling downwardly through the overflow pipe.

A feature of importance is the vertical adjustment of the baffle both with respect to the jet nozzle and the open end of the spray shield whereby the amount or volume of mist emitted may be nicely controlled. The baflie plate may be elevated above the opening of the spray shield to permit full volume of mist emission or may be lowered toward the end of the said shield to partially or completely close the same thereby governing the amount of mist delivered from maximum to nothing.

Other objects will become apparent during the description of the device shown in the accompanying drawing in which,

Fig. 1 shows a side view of several of my devices, two of these being in operation and the other one being closed.

Fig. 2 is a sectional view taken through the upper portion of my novel construction.

Fig. 3 is a fragmentary side view showing the baflle plate horizontally positioned.

Fig. 4 is a sectional view illustrating an angular adjustment of the baffle plate.

Fig. 5 is a sectional view showing the baffle plate in closed position, and

Fig. 6 is a sectional view taken along the line B6 of Fig. 2.

Like numbers refer to like parts in the several views. v

Referring to Fig. 1, numeral Ill indicates a water pipe supplying water under pressure and risers ll extend upwardly therefrom. Each of these risers l I, see Fig. 2, is connected to a sleeve member l2 by means of the threaded connection I3. The sleeve member l2 has a tapered conical outer surface asindicated at M and a central cylindrical surface as indicated at I5, and terminates in a threaded upper portion 16, the diameter of this upper threaded portion being less than the diameter of the smooth central cylindrical portion and, in turn; the diameter of the cylindrical portion i5 is less than the diameter of the threaded portion therebelow.

An orifice member 20 has a small cylindrical upper projection 21- and is provided with a finger gripping surface 22 whereby the same may be readily" connected to or disconnected from the threads [6 in the sleeve member 12. The orifice member 20 is provided with a cylindrical recess 23- anda small'orifice 24- extends upwardly therefrom and through the cylindrical portion 2|, this providing a passageway for water as will be readily understood. A screen member 25, shaped as shown, prevents foreign particles from clogging the orifice 24, such being frictionally inserted into the recess 23.

A cylindrical dome member 30 has an overflow pipe 3I' threadedly attached thereto as indicated at 32 and integrally formed vanes 33, see Figs. 2 and 6, extend inwardly and form a ring-like member 34, the inner surface of such beingtapered at 35 and receiving the conical tapered surface [4 previously referred to. Thus the cylindrical dome member 30 may be rotatably adjusted with respect to the riser pipe 25. The smallest diameter of the ring member 34, however, is of suflicient size to permit the dome member 30 to be lifted vertically over the finger gripping portion 22 of the orifice member 2|]. Thus the dome member 30 and its overflow pipe 3| may be removed whenever desired.

The dome member 30 has ears 36 extending upwardly therefrom at diametrically opposite points, these ears being slotted as indicated at 31.

A baffle plate 40 has a thickened portion 4| near its central portion, this thickened portion being bored and threaded at either end to receive the adjusting screws 50, see Fig. 2. It will be noted that the slots 37 terminate slightly above the upper edge of the dome member whereby the same will be completely closed, see Fig. 5,- whenever the studs 5d are loosened and gravity causes the baffle plate to assume the position shown. However, it is to be understood that in case my spraying device is used at an angle to the vertical that the baffle plate can be clamped in its closed position or any other position as desired.

The operation As shown in Figs. 1, 3 and 4, the baffle plate 40 is located at the extreme top of the slots 31 but in practice the studs are loosened and the baffle plate 4i) is adjusted to the desired height above the dome member 30 and at the same time the angularity of the same with respect to the horizontal is determined and the tightening of the means 58 maintains the baffle in its chosen position. Also, the dome member 30 may be manually rotated, the ring 3 5 turning upon the sleeve elemerit I2, and thus the direction of the vapor regulated. The unvaporized drops of water, see Fig. 4, gravitate downwardly through the dome member 30 and then into the waste pipe 3|.

When the impact plate is fiat, as shown in Fig. 3, the spray floats out all sides thereof while when the same is tipped, see Fig. l, the volume of the mist on the back side is decreased in proportion to the slope thereof, and the volume of the open side is increased in quantity and coverage. Due to the impact plate being on a slope, the mist shooting out of the open side rises higher in the air and gives greater coverage. Therefore, by raising or lowering the impact plate, and utilizing the set screw adjustment, the amount of mist developed whether the impact plate is flat or on aslant can be graduated.

By lowering the impact plate very close to the cylinder, and leaving only a very small opening, it is possible to cut down the spray, except for a very little amount of extremely fine mist which is a great advantage at certain times and on certain vegetables, to keep them from getting too wet.

Whenever desired, the set screws 5|! may be removed and the orifice element adjusted or removed by the finger gripping means 22, the screen 25 being removed and cleaned, if desired, and due to my particular construction, this is possible without elevating the dome 3i. and its waste pipe 3i from its normal position.

Having thus revealed this invention, I claim as new and desire to secure the following combinations and elements, or equivalents thereof, by

' Letters Patent of the United States,

I claimz' 1. A spray device comprising, a nozzle constructed to deliver a stream of water, a drainage member surrounding the nozzle and having an upward opening and an impact member having a flat impact surface located in the path of said stream and over the said opening of the drainage member, said impact member being mounted for adjustment both in a direction in alinement with said stream and as to angularity of its impact surface relative to said stream, said axis about which the tilting occurs being crossed by the prolongation of the path of the stream.
