ATOMIZING- APPARATUS.

Specification of Letters Patent.

Patented Apr. 2, 1912.

Application led November 1.0, 1910; SeraIkNo. 591,545.

To all 'whom t may concern Be it known that I, WALTER J. SMART, a citizen of the United States, residing in the city of New York, borough of Manhattan, county and State o-f New York, have invented certain new and useful Improvements in Ato-mizing Apparatus, of which the following is a full, clear, and exact specification.

This invention relates to atomizing apparatus and has for its object to provide a device of this character wherein a single atomizing head may be employed interchangeably for discharging material from a plurality of receptacles.

While applicable to many forms of ato-mizing apparatus, the present improvement is particularly kwell adapted for use in connection with air brushes. The device is compact and capable of utilizing material from a self-contained reservoir which may, for convenience, be the handle of the apparatus, from a detachable reservoir which may be in the form of a cup, or from a vessel located at a distance, which vessel may in practice be a bottle and the attachment comprise a rubber tube. These features `peculiarly V,adapt the device for use as an artists air inga part of this specification, a practicable I brush for artists use.

brush. l

In the illustration the atomizer head and associated parts are mounted eXteriorly of an elongated reservoir which constitutes the handle of the apparatus. Thus it will be seen that none of the operating parts is within the reservoir, all of'them being located on the o-utside of the same.

In the drawings accompanying kand formembodiment of a form of m'y'invention is illustrated. The drawings show' in full size the application of the invention to an air Figure 1 is a vertical longitudinal section. Fig. 2 is a top view,`partly in horizontal section. Fig. 3 is an end elevation showing a hose connection to the atomizing head; and Fig. 4 is anend view showing a cup attached to the atomizing head.

The handle portion of the device is illustrated as an elongated tubular or cylindrical body comprising a reservoir'. yOne A17 communicating therewith.

end of the reservoir is shown closed by an integral head 6, the other end carrying a removable closure 7. The reservoir may be filled upon the removal of the closure 7. The interior of the reservoir is free and clear, t-he operating parts being all mounted on the exterior of the walls thereof. The head 6 is shown provided with an opening, conduit as it were, 8, by which the contents o-f the reservoir will pass to the at-omizing head through the nozzle 9, which nozzle 9, owing to the fact that the contents of the reservoir` will generally, in practice, be liquid, will be herein designated the liquid nozzle. The port or conduit 8, opens into a chamber 10, disposed between the reservoir 5 and liquid nozzle.' There is shown a port or conduit 11 eXteriorly from the chamf ber 10, which conduit registers with the orifice 12 ofthe liquid nozzle.

The wall of the opening constituting the port or conduit 11 is shown screw-threaded for affording means of adjustment of the liquid nozzle relative to the cooperative nozzle. Since air underV pressure is at Vthe present time'ordinarily employed in atomizing the material applied by in air brushes, this nozzle will be termed an air nozzle and its associated parts and connections f air connections, etc. The air nozzle' is also adjustable relative to the liquid nozzle.

These nozzles are adjustable on intersecting axial lines. An air tube 14, is-mounted'eX- teriorly on one side of the reservoir handle and is shown project-ing beyond ther end 6 thereof. The air nozzle is carried by a screw-threaded connection with tube 14. f

The discharge'orifice 12 is shown' disposed at 'an' acute angle to the horizontal aXis of the reservoir and directed upwardly.v These definitions of position are such as thep'arts assume in the illustration. The compressed air, assuming, of course, as before stated, that airis the fiuid cooperating with the material supplied to the liquid nozzle, will be furnished Afrom some suitable source of supply andmay be supplied through a tube-having connection with a' nipple open. y

ing into a valve chamber 16,shown mounted on top of the tube 14C, yand having a port 'There isA shown a plunger form of valve reciprocatively mounted in the valve chamber and having a body portion 18, provided with a circumferential groove 19 adapted to register with the opening 20 in the nipple 15 and the port 17, and its normal portio-n to close communication between these ports, When the plungeris forced outward by the coiled spring 21. This spring is shown encircling a stem 22, an extension of the plunger, which extension stem is also guidedly supported by a closure nut 23 at the end of the valve chamber. A head or engaging portion 24 is applied to the outside end of the plunger and this is located in proper position for easy manipulation when the device is held in the hand. The passage of the contents of the reservoir 5 to the chamber 10 is controlled in the present illustration by a valve 25, constructed and adapted and located in position to seat o-n the ground seat formed at the outer face of the head 6 and at the port 8. The valvestem 2G is shown screw-threaded and provided With a knurled head 27. This valve will regulate the amount of material passing from the reservoir 5, or may shut olf all passage therefrom.

When material other than that contained in the reservoir 5 is required, the valve 25 will be actuated to shut off the floiv therefrom and another source of supply connected with the liquid nozzle, in the present illustration with the chamber 10. The Wall of the chamber 10 is shown provided with a port 28. This port is associated with a coupling device. In the present showing the coupling device is of simple construction, that is, a boss having a tapering seat 29 registering with the port 28. This tapering seat Will receive a. mating closure 30, when no outside source of supply is required, and will also receive mating connections from Some outside source of supply When such outside supply is to be utilized. Sometimes material Will be` furnished from a receptacle in the form of a cup 31, having a relatively-rigid tube 32, provided With a tapering connection 33 for engaging the seat 29. In some instances the outside source vvillbe furnished from a vessel at a distance, such, for instance, as a bottle. A nipple 34, having a taper connection 35, for the seat 29, is shown in Fig. 3. To this nipple a tube 36 Will extend from the vessel containing the supply. Thus it will be seen that it is possible to use the liquid froml three sources of supply; first from the handle reservoir 5; second by closing the valve 25, the handle receptacle is shut off and by removing the side plug 30 and attaching the cup 31, material may be sucked from the cup. The third Way is to insert the hose nipple 34; in place of cup and attach the rubber tube 36, running the same into a bottle or receptacle located Wherever desired and sucking the color from same. The coperating nozzles Will be adjusted one in respect of the other to cause the required spray to be delivered as occasion may demand.
