4 Claims.

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 in which there is a coil device for feeding the contained liquid to the exit opening.

Another object of my invention is a spraying device in which the fineness or coarseness of the discharged spray may be governed.

Another object of my invention is a spraying device in which the passage in the absorbent material through which air is forced to produce a spray can be supported and maintained from closing, thus insuring a free and uniform passage of air irrespective of the number of times the device has been used.

Another object of my invention is a spraying device in which the amount of liquid fed to the air stream for the production of a spray may, not only be regulated, but may'also be maintained during continued use.

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

The forced passage of air through a mass of saturated absorbent material in order to produce a liquid spray in spraying devices has the disadvantage that after considerable use of the device, the air pressure packs the absorbent material into such compactness as to seriously interfere with the passage of air therethrough, thus reducing, and at times preventing, the spraying I have overcome this serious disadvantage, by introducing a coil of material, such as of metal, through the absorbent material and passing the forced air through this coil. A liquid may readily pass into the coil interstices by capillary attraction, or through the action of the plunger, while at the same time it prevents all possibility of the absorbent material packing'or of preventing free 3.. passage of the forced air.

at each operation can be governed and controlled, which is not possible when the air is forced through a mass of absorbent material, the physical condition of which changes with use.

The construction of the devices of my invention presents many valuable features over the former described devices adapted for spraying liquids.

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

In the accompanying drawings, Figure 1 is a vertical cross-section of one form of a device of my invention.

Figure 2 is an enlarged cross-section of the absorbent material and coil elements of the device of Figure 1.

Figure 3 is a vertical cross-section of a modified form of a device of my invention.

Figure 4 is a vertical cross-section of a modified form of a device of my invention.

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

Figure 6 is a top view of a modified end element of Figure 5.

The particular form of the device of my invention illustrated in Figures 1 and 2 comprises a cylindrical member ID, one end of which is closed by the closure member ll, having a centrally positioned opening l2 therein.

Within the cylindrical member I0 is a plunger, 0r piston, comprising the member l3 of rubber, leather, fabric or other suitable material, having the two metallic discs I4 and 15 upon opposite sides thereof, and a rod I6 passing through centrally positioned openings in the members l3, l4 and I5 and extending through the opening I! of the closure member H, the exterior end of the rod I6 carrying the handle IT.

The other end, or exit end, portion of the cylindrical member [0 is covered by the fixedly attached closure member l8 having an opening I! therein.

Within the cylindrical member l0 and spaced from the end member I8 is a fixedly attached partition 20 having an opening 2| therein, thus forming 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. I

The opening IQ, of the member l8, 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 19 of the member Positioned below the chamber 22 and fixedly attached to the cylindrical member I is a liquidreceptacle 26 having a'tube 21 extending from the lower portion of the receptacle 28 into the chamber 22 through an opening 29 in the lower portion of the cylindrical member ID.

The operation of the device is as follows:

In order to first charge the absorbent disc 23 with the liquid 28 in the receptacle 28, 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 disc23.

When the disc 23 has been charged with the liquid 28 for the first time, the operation of the device is as follows: During the first charging of the disc 23, the liquid 28, by capillary attraction or otherwise, has entered the interstices between the coil 25. An inward movement of the plunger member [3 will force this liquid outwardly through the opening I}! of the end member I8 in the form ofa fine spray and will at the same time drawa supply of liquid 28 into the chamber 22 and the disc 23, through the tube 2'! and the outward movement will draw some of the liquid 28 from the disc 23 into the coil interstices and at the same time draw an additional quantity of the liquid 28 through the tube 21 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 28,.and that the interstices of the coil 25 will constantly have a supply of liquid 28 to be sprayed outwardly through the opening 19 of the member l8. I

- 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 I! is directed downwardly and a second handle 30 is positioned to allow of both handles l1 and 30 to be grasped by one hand,

,. the closing of which will force theplunger inwardly and the opening of the 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 38 is grasped by the hand and the thumbs of the hand employed to move the plunger inwardly by pressure upon the handle H.

The modified form of my device shown in Figure comprises a cylindrical member having the enlarged portion 34, the reduced forward end portion 35. The 35 rearward end portion of the cylindrical member 34 carries the member 38, extending outwardly 31, and then into the bulbous member 88, having an opening 39 therein. The end portion 38 is turned downwardly forming the cap 48 having an opening 4| therein. A resilient" hollow rubber ball 42 is removably attached to the 36-31-38 as shown.

ball 42, will allow air to enter the device drawformed respectively by the cylindrical elements 34 and 35 is a cylindrical absorbent member 48, having a longitudinal opening 48 therethrough. Positioned within the opening 48 is .a coil 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:

The rubber ball 42 is removed and suilicient liquid is introduced through the opening 38 to 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 of the coil 41 and outwardly of the opening 4| in the end 48 in the form of a fine The release of the pressure upon the ing some or the liquid in the absorbent material 45 into the coil 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 sufilcient 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 my invention presents: spraying devices in which the amount of liquid subjected to the spraying operation may be governed and controlled and that this quantity of liquid can be maintained during continued use.

I do not limit myself to the particular material, sizes, shapes, or positions of parts specifical; 1y shown and described as these are given solely for the purpose of clearly describing my invention.
