Application filed June 5, 1916. Serial N 0. 101,702.

Paint-Brushes; and I do hereby declare that" the followin isa full, clear, and exact description of t e same, reference being had to t e accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

In applying paint, varnish, and the like y dipping a brush into a paint or varnish pail and then working the brush over the surface to be painted, a considerable waste occurs due to the fact that in the transfer of the brush from the pail to the surface being painted, quantities of paint drop from the brush, or are splashed therefrom when the brush is actuated. This not only causes a waste of paint but oftentimes cause damage to surfaces where it is not desired.

This invention relates to improvements in painting outfits in which paint is forced from a tank or reservoir by means of an air pump, the paintbeing fed through the handle of a brush to the bristles thereof through a suitable rubber mouth piece or nozzle having. a restricted opening with the mouth pieceproevenly supply paint in desired quantities without waste or scatterin of the paint.

It is an object of this mvention to construct a painting outfit adapted to evenly supply paint to, and through a brush from a reservoir-tank by air pressure.

It is also construct a an object of this invention to pressure fountain paint brush,

adapted to receive paint through the brush handle and through a restricted opening in a flexible mouth piece disposed between'the brush bristles.

It is furthermore an object of this invention to construct a painting outfit comprising a paint receptacle having an air pum and a flexible air cylinder associated therewith, adapted to force paint by' air pressure through a passaged brush and rubber mouth piece to the brush bristles.

It is finally an object of this ll'lVBIltlOIl' to construct a fountain ipaint brush adapted to permit paint to be ed through the brush handle and through a rubber mouth piece on said handle, to the brush bristles by air pressure.

The invention (in a preferred form) is. illustrated in the drawings, and hereinafter more fully described.

In the drawings:

As shown in the drawings:

The device comprises a framework or casing 1, made up ofmetal strips and angle irons. Pivotally mounted oneach side at the upper end of the framework is a ring or attaching loop 2, adapted to be engaged by an adjustable strap 3, for carrying or hanging up the device. Said framework 1, has the angle irons disposed across the sides of its lower end, as clearly shown in Fig. 3, and is open at its upper end to receive a paint can, tank or receptacle 4, therein resting on the horizontal flanges of said angle irons. The can 4, has a centrally disposed concave portion 5, in its upper end, having an aperture therein in whlch is solderedor otherwise rigidly secured an outwardly threaded stub pipe or nipple 6, adapted to receive a coupllng nut 7, threaded thereon to connect one end. of a pipe 8, to said can. The bottom of said can 4, is convex and has a large circular central opening to the edges of which is soldered or otherwise rigidl secured an outwardly threaded downwardly projecting rim 9, for a purpose hereinafter described.

Rigidly and removably secured toone side of the framework 1, by means of brackets or metal straps 10, is an air receptacle or cylinder having a centrally apertured top plate 11, the outer edge of which is bent downwardly to afford a circular flange 12. Rigidly secured in the aperture in said top plate 11 is an outwardly threaded nipple or stub pipe 13, to receive a coupling nut 14, to connect the pipe 8, with said air receptacle. The bottom of said air receptacle comprises a base or bottom plate 15, the outer edge of which is bent upwardly to afford a circular flange 16. Secured to said circular flanges 12 and 16, in a manner to prevent air leakage, is, a rubber cylinder or tube 17. Formed or rigidly secured in the center of said base plate 15, and projecting inwardly into the to the lower end of an air pump comprising a cylindrical casing 22, having a plunger head 23, and plunger rod 24, therein adapted to be moved upwardly and downwardly within said pump casing by means of a handle 25, on the upper end of the rod 24, to

pump air into the air receptacle. Said air pump is secured to one side of the frame work 1, adjacent and parallel to the air receptacle by means of metal brackets or straps 26.

. Threaded onto the rim 9, of the paint can 4, is a cap 27, having a valve or sto cock 28, secured thereon to control the ow of paint from the can nected at one end to said valve 28, and having its other end connected to a second valve or stop cock 30, secured to the upper end of a handle 31, of a fountain paint brush. Said handle 31, has a centrally disposed tube 32, extending therethrough, the upper end of which is connected with the valve 30, and the lower end being open and terminating at the lower end of the handle. Connected to the tube 32, on opposite sides thereof and extending obliquely therefrom through the lower end of the handle 31, are auxiliary tubes 33,

i the lower ends of which are alined with the lower end of the tube 32. The lower end of the handle 31,is provided with a peripheral recess or groove adapted to permit a mouth piece 34, made of rubber or other suitable material to be secured to the handle as clearly shown in Fi or mouth parallel to the lower end of the handle opposite the lower open ends .of the tubes 32 and 33. Also secured by any suitablemeans in the groove at the lower-end of the handle and surrounding the mouth' piece, 34, are brush bristles 35, of any required kind, the upper ends of which are pressed together by a band 36 of anysuitable material secured around the lower ortion of the handle to assist in holding t e bristles in position.

The operation is as follows:

device as shown inFig. 1, maybe carried I by a painter or operator by means of the strap 3, which may be hung around the neck or over the shoulders of the operator. The

.through the I air 4, through a hose 29, congs. 5 and 6, with the tubes. 32 and 33, commumcating with the interior" valves 28 and 30, are closed and the air pump is operated by actuating the plunger head 23, in the casing 22, to pump air valve 18, into the air receptacle, the rubber cylinder 17, forming the sides thereof being adapted to stretch to permit the air receptacle to hold air under pressure, the valve 18, being automatically closed by theair pressure in the receptacle. The valves 28 and 30, may now be opened any desired amount. The air under pressure from the air receptacle flows upwardly through the pipe 8, into the paint can 4, forcing the paint downwardly through the valves 28 and 30, and the hose 29, through the tubes 32 and 33,'into the rubber mouth piece 34, from which position the paint is forced evenly between the li s of the mouth piece thus saturating the rush bristles 35, with paint, which may now be applied tothe surface to be painted in the customary manner. The amount 'of paint supplied to the brush is of course controlled by the valves 28 and 30. i

It is evident from the drawings that the paint can 4, when empty may be replaced by a full can of paint by simply removing the cap 27, and the pipe 8, and that the flow of paint through the lips of the mouth piece 34, is dependent upon the air pressure in the air receptacle and the adjustment of the controlling valves 28 and 30. The flexibility and shape of the mouth piece 34, also-tends 1 tubes 32 and 33 from drying out and clogging the brush.

I am aware that various details "of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limitingthe patent granted otherwise than necessitated by the prior art.

. I claim as my invention: 1. In a device of the class described the combination of a portable paint can, with an air pump mounted to one side thereof an elastic air cylinder mounted adjacent sai pump and connected at its bottom with said P p brush paint can, controlling valves therefor, and means in the bottom of said elastic air cylinder adapted to admit air under pressure from said pump into said cylinder to-force paint from said paint can through said I brush when the controlling valves are open.

2. In a device ofthe class described the combination .of a portable frame, a paint When it is desired to do any painting the can removably supported therein, an air valves therefor, an air receptacle'connecte and at its top with said paint can, a connected with. the bottom of theat its bottom 'with said-pump and at its top Valve in the bottom of said receptacle adapt- 5-ed to admit air under perssure from said pump into said receptacle to force paint from said can through said brush when said controlling valves are open.

In testimony whereof I have hereunto STANLEY GASPARAITIS.
