STANLEY GASPARAITIS, 0F GHICAKGO, ILLINOIS.

roUN'rAm PAINTBRUSH.

Application led December 10, 1921. Serial No. 521,289.

To all whom t may concern:

Be it known that I, STANLEY GAsPARArris, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Fountain Paintbrush; and I do hereby declare that the following is a full, clear, and

exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to fountain paint brushes in which paint is delivered to the brush through its handle from a suitable container by means of air or other pressure.

It is an object of this invention to provide a new and improved brush.

It is a further object of this invention to provide a brush and a setting for its bristles that may be manufactured and sold as a unit apart from the handle.

It is a further object of this invention to provide a removable substitute for the sheet metal ferrule usually found on paint brushes.

Other and further important objects of this invention will be apparent from the disclosures in the accompanying drawings and specification.

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

On the drawin s:

Figure 1 is a si e elevation of a brush con` structed in accordance with the present invention.

Figure 2 is a transverse section of the brush.

Figure 3 is a longitudinal section of the brush.

As shown on the drawings:

The brush is formed with a hollow handle 1 extended to accommodate the usual wide fiat form of paint brush although it may be given any other shape to accommodate any desired form of brush.

The edge of the handle nearest the brush extends beyond the setting of the bristles and forms a housing therefor, as shown at 2. A web extends across the hollow handle at the beginning of this housing to aord a bearing against which the setting of the bristles abuts, as shown at 3. It includes several portions which extend completely across the narrow part of the brush, as shown at 4. At each end of the housing ears 5 are provided for the reception of screw 6 for attaching the brush.

The setting of the bristles comprises a metal frame 7, which is provided with a iange 8 adapted to seat upon the edge of the housing. This ange also has ears 9 extending over the ears 5 to cooperate with the screws or bolts 6. The central portion of the housing is occupied by a filler block 10. Through this filler block go holes 11, preferably each lined with a metal sleeve, although the latter is not essential. The filler block 10 is surrounded by a piece of cloth 12 which extends up into the midst of the brush. The space around the filler block, both within and without the cloth 12 is filled with bristles. 'Also there are bristles abutting against the u per surface of the filler block and complete y filling the space within the cloth. The bristles are all held in place by glue which makes the block and the ends of the bristles and of the cloth constitute one solid mass llingthe frame 7 completely. At a distance from the housing the bristles are surrounded by a frame 13. This frame is supported from the ears 9, being held in place by the bolts or nuts 6. For this urpose the frame is provided with upright parts 14 and with horizontal ears 15.

In the operation of the device the brush is connected to the source of paint under pressure which enters the handle 1 and passes through the holes 11 and emerges in the midst of the bristles inside of the cloth 12.

The action of the bristles in spreading of paint tends to produce too great an accumulation of paint at each edge of the brush. This is partl prevented by the action of the cloth an partly by the frame 13 in restraining the degree to which the bristles flex. A uniform distribution of paint throughout the width of the brush is thus obtained.

The brush ma be cleaned by blowing air under pressure t rough the handle 1.

In applying the brush to the work the frame 13 acts to prevent too great a flexure of the bristles in the same way that the usual sheet metal ferrule surrounding the brushes now employed acts. The collection of bristles with the parts that are permanently attached thereto, namely the frame 7 and the filler block 10 are rml fastened t0- gether by means of a filling o glue, rubber or other cementing material. n addition,

if desired, screws may be passed through the walls of the frame 7 into the filler block. The brush apart from the handle andthe paint supplying arrangement may be sold as a separate unit, to replace brushes which have been worn out or so that the painter may have a supply of brushes at hand which would enable him to 4change quickl from one color to another by merel blowlng out the paint from the tube an fixtures and substituting a new can of paint and a fresh brush.

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

I claim as my invention:

1. A paint brush comprising a hollow handle, bristles supported by said handle, a pervious cloth funnel arranged within the bristles for controlling the. flow of paint to the bristles from said handle and a rigid frame secured to said handle and surrounding said bristles at a distance from the point of attachment of said bristles adapted to' retain the latter in contact with said funnel.

2. A paint brush comprising a hollow handle having a recess in its end, a liller block seated in said recess, means securin said block to the handle, an annular ring o bristles arranged around the periphery of said block, a cloth funnel arranged around the last named set of bristles, and a second set of bristles arranged around the funnel, said filler block having an aperture therein for the passage of paint from said handle to said funnel, and a frame secured to the handle and surrounding said bristles at a distance from said filler block to retain said outer set of bristles in contact with said funnel.

3. A paint brush comprising a hollow handle, a filler block attached to said handle, an annular ring of bristles arranged around the periphery of said block, a funnel arranged around the last named set of bristles, and a second set of bristles arranged around the funnel, said filler block having an aperture therein for the passage of paint from said handle to said funnel.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.

STANIJEY GASPARAITIS.
