sclaims. l(c1. 299-88) My invention relates to spraying devices and refers particularly to liquid spraying devices.

One of the objects of my invention is a spraying device of convenient operation and positive action.

Another object of my invention is a spraying device having a minimum of moving parts.

Another object of my invention is a spraying device in which a supply of liquid is maintained within the device itself.

Another object of my invention is a spraying device whereby a liquid will be broken up into a pluralityof parallel streams prior to its emission from the device.

Another object of my invention is a spraying device in which a plurality of parallel streams of a liquid is forced directly at the exit opening of the device.

I Another object of my invention is a spraying deviceV in which aplurality of parallel streams of a liquid is the resultof a plurality of strand-like elements within the device.

Another object of my invention is a spraying device in which practically all of the air passing therethrough during operation will 'be expended in forcing a` plurality of parallelstreams of air through the exit opening. i

Another object of my invention is a spraying device in which a liquid is automatically positioned for conversion into `a plurality of moving parallel streams during the operation of the device.

' The above-mentionedand other, valuable features of my device will be evident upon a consideration of my specification and its accompanying drawings.

I have found that greatly increased spraying effects of a liquid can be accomplished in a spraying device of such construction that a plurality of liquid streams is directed to the exit opening of the device;

It would seem that under these conditions each stream is broken up, or atomized, vinto a ne mistlike spray, much ner in its physical condition than results from the passage of a single stream through the same exit opening.

Irrespective of the theory underlying the operation, the spray thus produced is finer in its physical condition and has a greater spreading effect than those producedV where the surface of the liquid forced through the opening is equal to the area of the opening.

In the accompanying drawings illustrating several modifications of my device, similar parts are designated by similarnumerals. i

i In the'accompanying drawings,

Figure 5 is a vertical cross-section of a modied form of a device of my invention.

Figure 6 is a top View of a modified end ele-- ment of Figure 5. l

The particular form of the device of my invention illustrated in Figures 1 and 2`compris`es` a cylindrical member I one end of which isl closed by the closure member I I, having a centrally po# sitionecl opening I2 therein. Y l

Within the cylindrical member ID is a plunger, or piston, comprising the member I3 of rubber, leather, fabric or other suitable material, having the two metallic discs I4 and I5 upon opposite sides thereof, and a rod I5 passing through centrally positioned openings in the members I3, I4 and I5 and extending through the opening I2 of the closure member II, the exterior end of the rod I6 carrying the handle I1. Y

The other end, or exit end, portion of the cylindrical member I0 is covered by the xedly attached closure member I8 having an opening I9 therein.

Within the cylindrical member il) and spaced from the end member I8 is axedly attached partition 2D having an opening 2l therein, thus form-` ing a chamber 22.

Within the chamber 22 is a disc 23 of absorbent material of felt, asbestos, or other suitable material and having an opening 24 therein.

The opening I9 of the member` I8, the opening 2| of the member 20 and the opening 24 of the member 23 are in alignment with each other and I prefer that the opening I9 of the memberk I8 be of smaller diameter than the opening 24 of the member 23.

Within the opening 24 of themember 23 is a plurality of parallel positioned strand- like elements 25, 25 which may be of fibre, hair, bristles, synthetic resins, wire, glass-or other suitable materials.

Positioned below the chamber 22 and ixedly attached to the cylindrical member I0 is aliquidreceptacle 26 having a tube 21 extending from the lower portion of the receptacle 26 into the cham-A ber 22 through an opening 29 in the lower portion of the cylindrical member IU.

The operation of the device is as follows:

In order to rst charge the absorbent disc 23 with the liquid 28 in the receptacle 23, the piston is moved inwardly and outwardly a few times, and during each such inward and outward movement a portion of the liquid 28 is drawn upwardly through the tube 21 into contact with the absorbent disc 23.

When the disc 23 has been charged with the liquid 28 for the first time, the operation of t-he device is as follows: During the rst charging of the disc 23, the liquid 28, by capillary attractionY or otherwise, has entered the interstices between the strands 25, 25, or the interstices within the strands themselves, or both, dependent upon the material of the strands. An inward movement of the plunger member I3 will force this liquid outwardly through the opening I9 of the end member I8 in the form of a fine spray and will at the same time draw a supply of liquid 23 into the chamber 22 and the disc 23, through the tube 2l andthe outward movement will draw some of the liquid 28 from the disc 23 into the strand interstices and at the same time draw an additional quantity of the liquid 28 through the tube 2l into the chamber 22 and the absorbent disc 23 It will thus be seen that the absorbent disc 23 will be constantly supplied with the liquid 28and that the interstices of the Strands 25, 25 will constantly have a supply of liquid 28 to be sprayed outwardly through the opening I9 of the member I8.

The modified form of my device shown in Figure 3 is similar to that shown in Figures 1 and 2, except for convenience with one hand, the handle I1 is directed downwardly and a secondhandle 38 is positioned to allow of both handles Il and 30 to be grasped by one hand, the closing of which will force the plunger inwardly and the opening of t-he hand will allow the spring 3| to move the plunger outwardly.` A second supporting guide member 32 is introduced as an additional guide with the member I I.

The modified form of my device illustrated in Figure 4 is similar to that shown in Figure 3, and is a one-hand operated device, in which the handle 30 is grasped by the hand and the thumbs of the hand employed to move the plunger inwardly by pressure upon the handle 33.

The modiiiedform of my device shown in Figure comprises a cylindrical member having the enlarged portion 34, the reduced forward end portion 35. The 36 rearward end portion of t-he cylindrical member 34 carries the member 33,' extending outwardly 3l, and then into the bulbous member 38, having an opening 39 therein. The end portion 33 is turned downwardly forming the cap 40 having an opening 4I therein. A resilient hollow rubber ball 42 is removably attached to the 36-31--37 as shown.

Positioned within the chambers 43 and 44, formed respectively by the cylindrical Aelements 34 and 35 is a cylindrical absorbent member 45, having a longitudinal opening 46 therethrough. Positionedl within the opening 4B is a plurality of 'parallel vstrands 41`-41 similar to those previously-described in the device of Figures 1 and 2. A removable closure cap 48 is carried by the extension portion 35.

The. operation of this form of my device is as follows: l

The rubberbali 42 is removedand suflicient liquidis introduced. throughtheuopenin'g 39 to 75 saturate the absorbent material 45 and the rubber ball 42 is replaced and the cap 48 is removed. A collapsible pressure will force air through the interstices between the strands 41-41 and outwardly of the opening 4I in the end 48 in the form of a ne spray. The release of the pressure upon the ball 42, will allow air to enter the device drawing some of the liquid in the absorbent material 45 into the strand interstices, in addition to the natural capillary attraction of the strands. It is evident that this spraying operation may be continued as long as there is sufficient liquid within the absorbent material.

Figure 6 represents a multi-opening element which can be substituted for the single opening element 38 of Figure 5.

It will thus be seen that during the operation of my devices, a plurality of parallel liquid streams is forced into the exit opening, and that a supply for the production of such streams is furnished by an absorbent material and formed into such streams through the medium of the parallel strands.

By the word paralleL I do not limit myself to strands or streams of liquid which are absolutely parallel, but included in that word are elements which are so positioned with respect to each other as to produce the effects described by me.

I do not limit myself to the particular prod.- ucts, sizes, shapes, or positions of parts specically shown and described, as these are given solely for the purpose of clearly describing my invention.
