SPRAYING APPARATUS Filed May 24, 1944 Patented Nov. 19, 1946 UNlTED STATES PATENT OFFICE SPRAYING APPARATUS Henry Singer, Honolulu, Territory of Hawaii Application May 24, 1944, Serial No. 537,150

2 Claims.

This invention relates to a' spraying apparatus, and it is an object of the invention to provide an apparatus of this kind especially designed for use for the diffusion of a liquid in the form of a whirling mist.

Another object of the invention is to provide a device of this kind having novel means for effectively diffusing a liquid insecticide and to also provide an apparatus of this kind whereby the liquid is discharged in the form of a mist.

It is also an object of the invention to provide an apparatus of this kind constructed in a manner to permit the same, when not spraying, to be employed to advantage as a lamp or as a fan.

It is another object of the invention to provide an apparatus of this kind which can be easily knocked down and reassembled to facilitate cleaningand oiling when necessary.

Furthermore, the invention has for an object to provide an apparatus of this kind wherein the liquid is discharged or diffused upwardly in the form of a mist and wherein provision is made for regulating or controlling at will the upward throw of the mist.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved spraying apparatus whereby certain important advantages are attained, as will be hereinafter more fully set forth.

In order that my invention may be better understood, I will now proceed to describe the same with reference to the accompanying drawing, wherein:

Figure 1 is a view partly in vertical section and partly in elevation illustrating a spraying apparatus constructed in accordance with an embodiment of the invention;

Figure 2 is a view taken substantially on the line 2--2 of Figure 1; and

Figure 3 is an enlarged fragmentary detail view taken substantially on the line 33 of Figure 2.

As disclosed in the accompanying drawing, the apparatus is illustrated in the general simulation of a torchiere type floor lam and wherein is provided a hollow base member I from the central portion of which extends a tubular upright or post 2 in communication therewith. The base I has in communication therewith a suitably positioned drain 3.

Provided at the upper extremity of the upright or post 2 is a bell-like member 4 which constitutes a basin and with which the upright or post 2 communicates. The upper marginal portion of this basin 4 is surrounded by the upwardly and 2 outwardly inclined shel1 or apron 5 of desired inclination and preferred major diameter.

At substantially the axial center of the a ron 5 is an annular support or platform 6 of a major diameter slightly in excess of the diameter of the upper open face of the basin 4 but considerably less than the major or upper diameter of the apron 5.

Radiating from this support or platform 6 and disposed outwardly therefrom are the relatively narrow arms 1 terminating in the depending feet 8 which are suitably anchored, as at 9,, to the apron 5, or skirt as it may also be called, adjacent the upper or outer margin of such apron or skirt 5. These feet 8 are of such dimensions as to position the support or platform 6 a desired distance above the upper or outer margin of the apron or skirt 5.

The lower portion of the basin 4 and at desired points circumferentially therearound is provided with the inwardly disposed buttons I6 upon which is rested an electric motor M of any preferred type, with the power take-off shaft ll of such motor extending vertically upwardly and positioned at the axial center of the central opening 12 of the support or platform 6.

Positioned upon the support or platform 6 is a container C, herein disclosed as substantially semi-spherical in form, and which is provided at the axial center of its flat bottom wall I4 with a depending discharge nozzle l5 which passes snugly through the central opening l2 of the support or platform 6.

The'lower portion of the nozzle [5 is telescopically received within the upper open extremity of an elongated cylindrical chamber member It. This chamber member l6 has a relatively heavy bottom wall I! which is mounted upon the upper end portion of the power take-off shaft H and fixed thereto, by the securing means l8, for rotation therewith.

Associated with the container C is a compression pump I9, herein disclosed as of a hand type, while the upper end of the container C is provided with a filling opening 20 adapted to be closed in a conventional manner by the cap 2|.

The nozzle I5 is intersected by a plate 22 provided at its central portion with a valve casing 23 open at the top and bottom and in which is mounted a rotary valve 24 of a spigot type and which is operated by a stem 25 extending through the wall of the nozzle l5 and rotatably supported, as at 26, by a marginal portion of the apron or skirt 5. The outer extremity of the stem 25 carries a knurled head 21 or the like whereby tog sprayer 3|.

3 the valve 24 may be adjusted at will to either open or closed position.

Carried by the upper portion of the member IS and radiating outwardly therefrom are the fan blades 28 of a conventional type and of a desired number and which, upon rotation of the member I6, serve to create an upward stream of air.

Carried by each of the blades 28 and underlying the same is a pipe line 29, one end portion of; which, as at30, extends within the chamber member l6 while the opposite end portion of the pipe ine 29 extends through the outer portion of the lade 28 and a slight distance thereabove and said outer extension carries a mist diffusing or This sprayer 31 may be of any type preferred.

Suitably arranged upon the skirt or apron 5 at desired points therearound are the electric lighting elements 32 of a conventional type, the

conductors 33 therefor extending downwardly-of the post, Zand-out through a wall; thereof: at the lower. portion of said post. This conductor is adapted ffor connectionwith a suitable source of electric energy. Interposed inthe conductor and arranged; exteriorlyof the post- 2 isla controlling switch 34,.

\ The motor M is also in proper electrical connection, as indicated at 35, with'the-conductor cable-and such connection 35 is underthe control offa conventionaliswitch 36. It, is believed to be obvious that the motor can becaused-to operate independently. ofthe. lightingi elements 32. and vice versa. so that, when desired, the apparatus herein disclosedcan beemployed as' a fan-or as a lampjndependentlyof any spraying, function. The liquid, such as aninsecticidQ is placed within the container C and placed under proper pressure by the action-of thepumpl i With the valve 24 open, -the liquidwill enterv the lower; portion of the chamber member lfi-andunder such pressure will be forced'out through, the pipes 29 andnozzles [5,; so that eliective, diffusing of the uid in a mist r e will. be bta n d, This. diffusing of; themist'or fog will alsobe; further facilitated by placing-,themember; I6; together i the lad '8; ii -r n ,A lliqui that-may ropa rsrav tate upon. the apron or skirt: 5, will, rain n ot ehasin v and down throu h the post 2;;intothe: holl0w;ba$e;member I, whereby such iquid: ma be adily r cove ed. throu h the drain}.

It is believed to be obvious thatwiththe apparatus; as; herein disclosed; the; mist, or. fog; is thrown upwardly andthat such J upward; throw. of the mistor fogwill be. dependent uponthe, air compression, within the container (3. Obviously the greater such compression, the higher the throw of the mist or fog. During the time the mist or fog is being discharged, it is believed to be readily understood that the fans will create such air draft as to materially facilitate the desired difiusion and as the lighting elements 32 are located out of the path of rotation of the blades 28, such elements may be employed, if desired, during the period of diffusion. It is also believed to beobvious that. when either the fan blades 28 or the lighting elements '32 are being used collectively or separately, the valve 24 should be closed unless, of course, the spraying operation may-also be desired.

From the foregoing description it is thought to be obvious-thata spraying apparatus constructed in-accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated.
