COMBINEDSPRAY AND PINTBRUSH.

Application med apra 1o, 1922. serial No. 551,183.

To all whom t may concern:

Be it known that I, JOHN G. b'oHMiD'r, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Combined Spray and Paintbrushes, of which the following is a full, clear, and exact description.

My inventon relates to improvements in combined spray and paint brushes, and it consists in the combinations, constructions,

and arrangements herein described and claimed.

An object of my invention is to provide a combined spray and paint brush which has the advantages of the spray and of the ordinary paint brush without the disadvantages of either.

A further object of my invention is to provide a device of the character described in which a plurality of nozzles are used for applying the spray, whereby a more even coat of paint is effected.

A further object of my invention is to provide a device of the character described in which the spray is adjustable with respect to the paint brushes.

A further object of my invention is to provide a device of the character described in which the parts are readily assembled for use o r disassembled for cleaning.

A further object of my invention is to provide a device of the character described which is simple in construction, and is dura ble and eicient for the purpose intended.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended-claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which- Figure 1 is a side elevation of the device,

Figure 2 is a plan view of the device, and

Figure 3 is a longitudinal section of the spray.

In carrying out my invention, I provide a spray brush 1 which has an inner paint or other liquid receiving reservoir 2, and an annular compressed air chamber 3 (see Fig ures 1 and 3). The chamber 3 is disposed concentrically around the chamber 2 and is provided with an inlet. 4. The chamber lor reservoir 2 is provided with an inlet 5. The

5 chamber 2 has a plurality of outlet openings 6 which are alined with respect to each other and which are disposed on the opposite side to which the inlets 4 and 5 are disposed. Nipples 7 of the shape shown in Figure 3 are disposed in the openings 6 and project through threaded openings 8 in the outer wall of the chamber 3. It is obvious that there are as many openings 8 as there are openings 6, and that each opening 6 carries a nipple 7. The outer wall 9 of the member 1 carries nozzles 10. These nozzles have threaded Shanks 11 which are disposed in the openings 8, whereby the nozzles are securely locked -in place. The bore of the nozzles 10 are tapered and receive the ends of the nipples 6. If desired. the bores 12 of the nozzles 10 may be reduced so as to bear against the outer end of the nipples 6. In this case, the portion of the nozzle 10 which bears against the nipple 6 would be provided with grooves through which the compressed air from the chamber 3 is passed. The bore of the nipples 6 is alined with the exit opening 13 of the nozzles 10 so that paint or any other liquid in the container 2 may pass through the nipples 6 and out through the openings 13.

The outlets 4 and 5 are disposed in an annular projection 14 which is integral with the member 1. A hollow handle 15 is disposed over the projection 14 and has its sides 16 extended so as to enclose the sides of the member 1 (see Figure 1). The handle 15 encloses the

pipes

17 and 18 which are disposed in the inlet openings 4 and 5. The

pipes

17 and 18 may be threaded, if desired, so as to rigidly secure the pipes to the pro` jection 14. As clearly shown in Figure 2, the

pipes

17 and 18 are connected to conn duits 19 and 20, these conduits being provided with valves 21 and 22. The conduit 19 is adapted to convey compressed air to the chamber 3 and the conduit 2O is adapt* ed to convey paint or a like liquid to the chamber 2.

A metal saddle 23 is clamped in adjusted position to the handle 15 by means of a nut 24. This saddle has laterally extending arms 25 which are provided with slots 2G therein (see F'igure`2). Paint brushes 2T are secured to thearms 25 by means of set screws 28. It is obvious from the foregoing structure that the brushes 27 may be moved toward or away from the spray brush 1. It is also to be noted that the brushes may be swung angularly with respect to each other.

F rom the foregoing description of the various parts of the device, the operation thereof may be readily understood. rllhe handle 15 is preferably adjusted with respect to the frame 23 so that the nozzles 10 are spaced away from the endsv oli' the brushes 27. ln Figure l l have shown a dotted line 29 which represents the wall of an object to which the liquid, such as paint or the lilre, is to beapplied. The nozzles l0 do not touch the wall 29 and are preferably spaced the distance from the wall whichis shown in Figure l.

lin applying a liquid, such as paint or calcimine, to lthe wall 29, the valves 2l and- 22 are opened to the required distance so as to permit the required pressire to be applied to the compressed air and to the liquid. The liquid will How out through the nipples 6 and into the openings 13 where it will come into engagement with the compressed. air `from the chamber 8. rlihe compressed air will-drivethe liquid outwardly with-suiiicient force tomake a spray. rl`his spray will contactsi'viththe wall to whichA the device is applied. lin the useof ordinary sprays in 'which paint, varnish, calcimine, or other decorative coating is to be applied to a wall, a slight air current or a draft carries the atomized' particles fromy the point of the intended application, somev being entirely carried away and others being dropped on the ground'causinga loss of material and sloppy work.Y With my present device, however, the brushes 27 act as a protective shield and also apply the liquidon the wall in the manner in which the ordinary paint brush applies thel liquid to a wall. As' the liquid is being sprayed upon the wall, the device is moved so as to cause either of the brushes 27 to engage with the liquid on the wall. lt is ob-vious that the device may be moved as :tast as desired, since the liquid will be supplied to the brushes at a constant flow. The nozzles l0 are provided in a row so as to give a more uniform flow to the liquid and over a great area. As heretofore stated, the brushes 27 may be moved toward or away from the nozzles l0, or may be swung an ularly with respect to each other. he brushes may be detached and cleaned in the ordinary manner, or new brushes may be substituted for the old ones. As heretofore stated, the device is very simple in construction, and is eiicient and durable for the purpose intended. lt has the advantages of the paint brush and the spray without the disadvantages of either.
