Patented Jan. 30,1912.

Application filed November 3, 1910. Serial No. 5%,536.

To all whom. it may concern:

Be it known that I, NInLs lvlARrrN HAN- SEN, a citizen of'the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Air-Brush; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertain's to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates particularly to 'airbrushes; and has for its object to simplify andimprove upon apparatus of this class, minimize the cost of construction thereof, and to attach the liquid receptacle and handle for relative adjustment to suit the angle at which it is desired to hold the receptacle or the handle to render access to corners or the like.

Further objects of my invention, as well as the operation, construction and arrangementof the parts thereof, are fully described in the following specification, and while the invention, in its broader aspect is capable of enibodiment'in numerous forms, a. preferred embodiment thereof is illustrated in the accompanying drawings, in which,

Figure 1 is a side elevation of an apparatus embodying the invention, with portions broken away. Fig. 2 is a top plan view thereof with a part broken away, and Fig. 3 is a front elevationof the receptacle top and parts carried thereby, with the handle turned at an angle to the axis of the top.

Referring to,,the drawings, 1 designates a receptacle of airy-suitable form for liquid paint, powder or other matter which it is desired to apply to a receiving surface, and 2 the cover thereof. To facilitate an easy and quick removal of the cover from or its application to the receptacle, the cover is' fitted over the shouldered or beaded edge 3 of the receptacle and provided at different points on one side edge thereof with lugs or hooks 4:, which engage under the shoulder 3' and serve to hold' such side of the cover to its seat on the receptacle. Atthe side of the cover opposed to the lugs t, or-substantially midway between such lugs, is pivoted an angled latch-finger 5, which has a thumb engaging portion projecting outwardly from the edge of the cover and a portion lying along the cover edge and provided at its free end with lips 6, one of which en-- gages over the cover edge and the other 'under the cover edge and shoulder 3 to 00- operate with the lugs 4 to hold the. cover to its seat on the receptacle. A spring 7 acts -on the latch finger to normally retainit in looking engagement with the cover and shoulder. A tube 8 projects from near one side edge of the cover down into the receptacle to adjacent its bottom andis-provided at its upper end without the cover with a restricted discharge nozzle 9, the

throat of which inclines outwardly in the direction of the adjacent edge of the cover, as shown, or in the direction in which the spray is tobe discharged.

Rising from the cover 2 in a diametrical line with the nozzle 9 are'one or more standards 10, which provide bearings for an airtube 11. This air-tube is disposed diametrically of the receptacle top and is held to the standards 10 for rotary adjustment relativc thereto by cap-pieces 12, which hinge at one end to the standards,- as at 18, and have their other ends secured thereto by thumbscrews 13, as shown, thus enabling the tube to be securely clamped in adjusted position to the standards. The air-tube 11 has its discharge end provided 1 with a restricted nozzle 14, which, when in operative position,

is disposed to direct its air discharge across the nozzle 9, to ,create a suction through such nozzle and its tube, as is Well understood in the art.

The air-tube 11 has the end thereof which is opposed to its nozzle projected beyond the edge of the cover 2 and provided with an elbow 15, to which a handle 16 is threaded or otherwise suitably secured. This handle projects down at the side of the receptacle 1, preferably at right angles to the air-tube 13, and has a tube 17 projected axially therethrough with its inner end in connection throu h the elbow 15 with the bore or channel of the air-tube, and is adapted-atits outer end for connection with a suitable source of air supply under pressu're. '13.

valve 18 is located in the elbow l5 and normally-held seated to close the airpassage dil name

To facilitate an agitating of the liquid.

Within the receptacle 1 to prevent a settling of the heavy particles held in suspension Within the liquid, a branch tube 22 extends from the air-tube 11 down through the cover 2 and into the receptacle to near its bottom to permit a discharge of air from the tube 11 into the receptacle. A valve 23 controls the passage of air through said branch tube, as is apparent. To permit a swinging of the tube 22 With the tube 11 when rotatably adjusted a transverse slot 2 is provided in the cover top for the tube 22 to project through. This slot is of sufficient Width to permit. of a limited longitudinal adjustment of the tube '11 and attached parts.

In the use of my improved air-brush,

the operator, having first adjusted the air nozzle 14: relative to the nozzle 9 to suit the form of spray desired, grasps the handle 16 with one hand and Works the valve 18 with his thumb to control the air discharge from the nozzleld across the nozzle 9. If it is desired to turn the handle relative to the receptacle to better facilitate the use of the device in cramped places or for spraying corners or the lilre,'the screws 1-3 may be loosened to permit a turning of the tube 11 Within the standards 10 to place the handle 16 at the desired angle relative to the receptacle and then tightened to lock the handle in such position. This tteature is found to be quite important in th oractical and cilicient operation of a do ice of this class. The mounting of the air-tube within the standards 10 as described, also permits "an easy and quick relative adjustment of the nozzles 9'and 14 and a re: d of the tube from the standards to facilr. Le a cleaning of the parts.

I Wish it understood that my 5 not limited to any'particulai" :ruction or arrangement of the parts creep in so :tar as such limitations are specified the claims.

Having thus described my invention, What 1' claim as new and desire to secure by ters Patent, is,

1. In an air brush, a receptacle, a tube e3:-

tending therein and having a nozzle with- .uvent ion is out the receptacl 'an air tube extending across the top of the receptacle and having one end. terminating adjacent to said nozzle and its free end extending beyond the side of the receptacle and thence downwardly at the side of the receptacle to form a handle, and means on the top of the receptacle for carrying said tube for adjustment transversely of the receptacle and for swinging adjustment to permita placing; of the loandle portion of the tube at different angles relative to the receptacle.

lln an air brush, a receptacle, a tube extending therein and having a nozzlewithout the receptacle, standards on the top of said receptacle, an air tube mounted in said standards transversely of the top of the re-' ceptacle for rotary and longitudinal adjustment relative to the receptacle and having one end terminating adjacent to said nozzle.

and its other end angled and extending downwardly along" the side of the receptacle to form a handle, which is capable of swinging relative to the receptacle when said tube is rotated in said standards, means for clamping the tube in adjusted position. and

an air valve located Within said handle and the thumb of a hand grasping the handle.

In an air-brush, a receptacle, spraying means carried by the receptacle and having an air-tube extending transversely of one end of the receptacle and having one end projected beyond the side of the receptacle and angled to extend along the side of the receptacle in spaced relation thereto to form a handle, said an gled portion being in C0111 munication with the source of fluid under pressure, a valve located Within the handle portion of said tube and having a stem projecting axially therefrom Without the angled portion "of the tube and at substantially right-angles to the portion of the tubeprojecting across the receptacle, and a thumb piece carried by the valve store without the tube in position to be pressed by the thur'nb of a hand grasping the handle.

ln testimony Where-of, l have hereunto signed my name to this spexxitiration in the presence of two subscribing; witnesses.
