Application filed May 4, 1915". Serial No. 25,680.

To all whom it may concern.' i

Be it known that we, GEORGE MORE and EDWARD W. SEIES, both citizens of the United States, and residents, respectively, of Richmond Hill, in the county of Queens and of the borough of Bronx, in the county of New York,- State of New York, have in-A vented certain new and useful Improvements in Spraying Devices for Liquid Paint and the like, of which the following-is a specification.

This invention relates to spraying devices for paint or the like, and it comprises, in a liquid paint receptacle having atomizingk munication with a source of pressure supply.,

ne of; said nozzles being adjustable relaively to the other, whereby the degree of suction force exercised by the air jet across thel paint delivery nozzle may be varied to thus regulatey the quantity of'paint drawnv outwardly and atomized. By this means a lighter or heavier coat of paint may be. applied to the surface under treatment, to suit the requirements. s

v:The handle by which the receptacle is carried and operated in practice, is arranged relatively to the position of the air jet nozzle in such manner that when said handle is grasped by one hand of the operator, the atomized paint is then directed forwardly of the operator toward the work, and we provide a controlling valvev in the line of the compressed air supply, for convenient op eration by the same hand of the operator with which the receptacle handle is grasped, whereby the receptacle may be carried, the paint spray therefrom directed, and the atomizing air controlled, all by manipulation of a single hand.

The air pressure nozzle. -is pivoted inl manner to rock through aY vertical arc, whereby its attack across the orifice of the vertical paint delivery nozzle may be varied,

adjustment being effected by a thumbscrew,

-thumb screw beingA conveniently disposed acting upon said air pressure nozzle, to regulate its degree of rocking movement, and thus to direct its angle of attack, said for manipulation by the other or free hand of the operator.

Other features andadvantages will hereinafter appear.

In the drawing: Figure 1 is a side elevationof an apparatus embodying our improvements. Fig. 2 is a vertical sectional View thereof, and Fig. 3 is a top plan view. In carrying out our invention we employ a receptacle for liquid paint, as l, which may be in cylindrical form and of suitable size to contain a quantity of paint or the like, the combined weight of the receptacle an'd its contents being such as to be capable of convenient handling by the operator with one hand. The receptacle is provided with a removable top or cover, which may be in the form of a screw cap, as 2, which latter may also serve as a mount for the spraying orA atomizing devices, whereby the liquid paint ontents of the receptacle are applied to a surface to be coated.

A tube 3 extends downwardly fromcap 2 within the receptacle, for the passage of fluid paint, said tubepenetrating the cap, and terminating above said cap in a delivery nozzle 4. An air delivery nozzle 5 is also mounted upon cap 2, having trunnions 6 by which it is pivoted in bearings 7, said nozzle lying in a substantially horizontal position, with its exit orifice directed across the vertical aXis of the nozzle 4, and said nozzle 5 being thus capable of swinging vertically, to vary the angle at which the air jet attacks the paint delivery nozzle, to thereby regulate the extent of the suction force set up-in inducing the exudation of paint from said nozzle 4e for atomization.

The nozzle 5 has a laterally enlarged portion or offset, as 8, through which is provided a vertical, threaded orifice, toreceive a thumb screw 9, whose free end is adapted to bear against the upper surface of cap 2, and thus, by turning said thumb screwl up or down, to regulate the angularity of nozzle 5 relatively to nozzle 4l. The nozzle 5, at a point anterior to its pivotal bearings, is tensionally connected to the upper surface of cap 2, as by a spring 10, whereby the regulating action of the thumb screw is rendered effective.

A handle, as 11, by which the receptacle is held for service by one hand of theoperator, is secured toward the rear portion of the receptacle wall, at one side of the ,media-l line occupied bv the horizontally disposed nozzle 5, thatposition for the han dle enabling it to be held most conveniently for the practice of the apparatus with the air nozzle directed toward the work. inthe illustration, the handle is shown as adapted for use by a right handed person, and its relative position may obviously be reversed for use by a left handed person. l

The nozzle 5 is supplied with air under pressure as by a flexible/tube' 12, which communicates with a valve, as 13, as by abranch ltube 14, said'valve also communicating, as

by a` branch tube 15, and a flexible tube 16 connected therewith, with a source of air pressure supply, as 16a. I have shown the valve casing as cylindrical, with a plunger tle to the left (in the example illustrated) of the handle 11, where it is in convenient p0- sition vto be operated b y thethumb of ,that hand of the operator grasping the handle, this being' as stated for use by a right handed person.

ed person. l

It will be apparent, from the foregoing description, that the operator .holding the device by its handle .11, with one hand, in. position to direct the induced, atomized paint toward the surface to be coated with paint, may withVA the free thumb .of the same hand depress the valve plunger for the supply of compressed air, and may at will shut off the supply by release of the thumb pressure, thereby allowing the valve spring to close the zvalve. Also, at the time of spraying atomizcd paint in the manner indicated,

the operator may, with his other hand, manipulate the thumb screw 9 to thereby rock the nozzle 5, for' the purpose of regulating .its angle and consequently the degree ofl suction applied to the paint nozzle 4. To

provide a quick means of connecting and disconnecting-the flexible tube 12 with nozl zle 5,. as -islnecessary inremoving and reapplying the cap 2, we may provide a threaded slip coupling, as 22, or equivalent device. A

Variations: maybe resorted towithin the `scope and spirit of our said invention, and

. parts thereof used Without others.
