BY JWW ATTORNEY United States Patent- PAINT BRUSH PROTECTOR AND SHAPER Application May 22, 1953, Serial No. 356,830 6 Claims. (Cl. 20615.1)

John Levy,

This invention relates to a brush protector and more particularly to a paint brush protector and shaper which will accommodate a brush after use and preserve the bristle structure, shape and pliancy.

It is conventional in the painting trade to clean thoroughly a brush once used to prevent oxidation of the exposed paint lest the bristles become hard from the oxidized paint which intimately associates With the bristles. Whether an animal bristle or synthetic bristle brush is used, preservation of the individual bristles for the life of the brush is always desirable. Many master painters, dissatisfied with the devices devised thus far drill a hole through the handle or ferrule and suspend the used brush with the bristles projecting into a paint solvent or even suspend the bristles of the brush into the paint which will be used on the following day so that the bristles remain pliable. However, merely suspending the unprotected bristles in solvent permits the bristles to spread and ultimately injures the bristle setting. To prevent this bristle deterioration and the inevitable loss of brush shape, some painters have found that wrapping the bristles with paper and dipping the wrapped brush into a liquid such as linseed oil enables the bristles to be preserved for a limited time.

Therefore, it is an object of this invention to provide a device which will confine a brush within a chamber of selected brush contour to preserve the bristle shape.

Another object is to provide a brush container which will accommodate a paint brush and a suitable liquid, solvent or paint to keep the brush bristles pliant.

A further object of this invention is to provide a brush protector which is compact, collapsible, and has a stand which will support the protector with liquid therein in an upright position.

Another object of this invention is to provide a brush protector with a collapsible stand which may serve to seal liquid chambers of the protector and thereby facilitate brush storage for extended periods.

A further object of this invention is to provide a brush protector which is simple in operation, easy and inexpensive to manufacture With a minimum of component parts, and durable.

Other objects and advantages of the present invention will become apparent to those skilled in the art from a consideration of the following general and detailed description of one embodiment of the present invention had in conjunction with the accompanying drawings in which the same indicia refer to the same or corresponding parts and wherein:

Fig. 1 is a perspective view illustrating the present invention in an upright position and showing a brush in position;

Fig. 2 is a side view, partially in section, and slightly enlarged of the brush protector with a paint brush in situ;

Fig. 3 is a top view of the brush protector illustrated in Fig. 1 and showing the details of the side pockets and the orientation of the brush in the central chamber;

Fig. 4 is an enlarged partial detailed view of the collapsible side pocket and chamber side wall.

Referring to the accompanying figures of the drawing and more particularly to Fig. 1 wherein there is illustrated a device constructed 'in accordance with the present invention and broadly described as comprising a central brush receiving chamber 10 with appending collapsible covered liquid-containing side pockets 12 and 14 which are pivotally connected to the chamber 10, and a pivotable stand 16 to support the device in an upright position or which is adaptable to seal the side pockets when the stand is pivoted to the alternate position as illustrated in the dot-dash lines in Fig. 2.

The central brush receiving chamber 10 is made with side walls 18 sufficiently wide to accommodate conventional brush widths. Each side Wall 18 has a perforated portion 20 intermediate the ends of the side walls 18 to permit ready infiltration of the liquid 19 suitable for the desired action on the brush bristles forming part of brush 22. The receiving chamber 10 is substantially wedge shaped in cross section and at the apex of the wedge is a hinge 24 to permit the central chamber to be opened completely as illustrated in the dot-dash lines in Fig. 2. To facilitate cleaning the chamber 10 after the brush has been removed chamber 10 may be opened on hinge 24, and such opening also permits the brush 22 to be placed fiat against one side Wall. In such operations the bristles 23 may be compressed as the side walls 18 are brought to the upright position as shown in Figs. 1 and 2. The end walls 26 are divided into two sections to facilitate separation and opening of the chamber 10 by permitting one section to slide and nest within the other section.

Disposed from each side wall 18 are side pockets 28 and 30 formed by side plates 32 and 34 which are pivotally connected to the side walls 18 by hinges 36. The hinged side plates 32 and 34- are securely located intermediate the ends of the side walls on the exterior part of the brush chamber and below the perforated section in the side wall 18. The volume of the triangular shaped side pockets 28 and 30 is limited by the prolongated side plates which have a projection 38 extending beyond the hinges 36 to buttress against the side Walls 18. Integral with the side plates 32 and 34 are triangular end sections 46 and 42 which project into the brush chamber 10 through elongated apertures or slot 44 in the chamber side walls 18. The edges of the triangular end sections may be upset or a piece of flat stock Welded thereon to form an enlarged T rib 46, best illustrated in Fig. 4, to buttress against the internal portion of the side Wall 18 as the side pockets are spread to the open position to receive the solvent, paint or other liquid media suitable to preserve the brush bristles 23.

A flap or cover 48 pivotally aifixed on each side pocket protects the cleaning solvent from evaporation and also, Where paint is used, oxidation is appreciably retarded for extended periods. As an alternative for the liquid placed in the side pockets, any suitable absorbent material, such as cottonwaste, may be saturated with a solvent such as linseed oil and the wadding will prevent spilling and permit infiltration and absorbtion by the bristles 23 through the perforations in the side walls. The covers 48 are designed to be raised, as illustrated in the dot-dash line position of Fig. 2 when the device is opened for use. However, to provide compactness in storage the covers 48'may be made to fold into a side pocket 28 or 30 by slightly springing the respective side plate outwardly and then depressing the cover so that the cover lip 50 will clear the side wall and will lie flat against the side wall 18, as shown in Fig. 4. The cover hinge 52 has a prolongated hinge pin 54 which is offset intermediate the ends of the cover 48 and free to rotate in the recess 55 in side wall 18. The hinge pin 54 is bent at the ends to m hool'li 'e r abers 57 which pass transversely across brush chamber to reieasably engage with the eyelets on the opposite side walls from the hinge position. The hooklike members 57 may be modified to increase or c ease the opening in the chamber 10 to. afford suiiic ent pressure of the side wall against the bristles 23.

Disposed intermediate the ends of the side walls 18 and laterally beyond the side plates of the side, pockets are brackets 58 secured as by welding to the side walls 13 to support pivotally a wire stand 60 which will permit the protector to stand in an upright position as the stand buttresses against proiecting pegs 62., secured to the side plate of the side pockets, as illustrated in Fig, 1. However, the stand 69 will serve another purpose when the stand on each side of the protector is. rotated so that the cover 43 is engaged by the stand to. lock securely the cover against the side pocket, thereby facilitating storage and portability without excessive spillage, as shown in the dot-dash line of Fig. 2. Slightly springing the wire stand 60 will permit rotation of the stand beyond the projecting pegs 62.

To assure that liquid seepage is kept to a minimum the entire assemblage may be provided where necessary with liquid seals or gaskets, at the junction of the various components. Chamber seal 64 at the apex of the wedge will be compressed as the side walls are substantially vertical and the brush 22 may be provided with a ferrule, seal or gasket 66, or this sea] may be atfixed within the chamber 10 at the desired position. Side plate gasket 63 serves to prevent seepage between the side walls 18 and at the prolongation of the side plates 32 and 34. Edge gasket 76 on the T ribbed end sections of the side pockets within the chamber 10 assures against seepage through the elongated apertures 44 in the side walls 18. The split end walls 26 being divided into two sections slidable relative to one another are provided with gasket 72. The gasket material desirable may be either rubber, neoprene, nylon, or similar material or combination thereof which will be impervious to liquid seepage.

Although the operation of the several parts of the paint brush protector has been described in detail above it is believed desirable to summarize the operation of the device in its entirety. After the brush has been used the excess paint may be removed and the protector opened to receive the brush by spreading the side walls 18, as in Fig. 2, in the dot-dash lines, and then placing the brush with the bristles 23 flat against the interior of the side walls 18 and then bringing the side walls together. By adjusting the hooklike members 54 to obtain suitable bristle compression and suitably placingthe hooks into eyelets 56 the covers 40 will be pivoted out of the side pockets and the T ribs will be forced. outwardly to form the side pockets. The stand may be placed in the up right position but, of course, this is optional with the operator. Suitable solvent, cleaner or paint may be poured into the side pockets and will then pass through the perforated side walls into the central chamber 10 to come into intimate contact with the brush bristles 23. By rotation of the stand the covers 40'may be securely retained to prevent undue liquid loss.

From the foregoing description, it. is readily apparent that a brush protector constructed in accordance with our invention is particularly well suited for the intended purposes, by reason of the convenience and facility with which it may be operated. Obviously, many modifications and variations of the present invention are possible in light of the above disclosure. It is therefore to be understood that within the scope of the appended claims the invention may be practiced otherwise than as specifically described.
