' PAINT BRUSH Filed. Feb. 1 1960 INVENTOR. F1 Dani Philip L. BY

United States Patent @ffrce 3,023,439 Patented Mar. 6, 1962 York Filed Feb. 1, 1960, Ser. No. 5,965 8 Claims. (Cl. 15-143) This application is in part a continuation of my copending application Serial No. 843,429, now abandoned, filed September 30, 1959.

My invention relates to paint brushes and has to do more particularly with an improved construction utilizing a novel hollow handle structure, preferably formed of molded plastic or other suitable material.

For many decades paint brushes have generally followed a more or less standard design employing wooden handles to which were attached metal ferrules carrying a body of bristles- Such an arrangement was for many years considered economical to fabricate and generally satisfactory.

However, with increased labor costs required for the production of wooden handles and increasing scarcity of wood, it has been considered highly desirable to find other materials which might be substituted for the standard wooden handle. Various materials and constructions have been suggested but none has been entirely satisfactory.

In Pettengill patent No. 2,532,780, granted December 5, 1950, it is suggested that a paint brush handle be formed as a hollow casting of a suitable light-weight metal such as magnesium, the handle being attached to a standard bristle-carrying ferrule by means of an intermediate wooden block for receiving the brads which attach the ferrule to the handle. Since the issue of that patent the market has seen the appearance of somewhat similar brushes utilizing a synthetic plastic handle in lieu of the metal disclosed by Pettengill, also utilizing a wooden block. While brushes of this type represent some advantages as compared with the standard wooden-handled brush, they nevertheess have not been an entirely satisfactory solution of the problem because of the necessary use of an intermediate wooden block to receive the nails or other fastening elements, adding to the cost of materials and labor.

According to my invention I employ in conjunction with a standard bristle-carrying ferrule a hollow handle consisting entirely of plastic or other suitable moldable or castable material which is attached directly to the ferrule without any intermediate block or other such element to constitute a brush which is entirely satisfactory for the required purposes.

A further object of my invention is provision of a paint brush handle which, while substantially hollow and preferably formed by casting or molding, nevertheless, has adequate strength and rigidity throughout, without the need for any supplemental reinforcing element, such as a wooden block as referred to above, and which is so designed that accidental flow of any substantial amount of paint into the interior of the handle is substantially prevented.

Referring now to the drawings forming a part of this specification and illustrating a preferred embodiment of my invention:

FIGURE 1 is a perspective exploded view of a paint brush embodying my invention;

FIG. 2 is an elevational view of the handle alone with parts cut away and shown in section;

FIG. 3 is a bottom plan view of the handle;

FIG. 4 is a sectional view taken substantially along the line 4-4 of FIG. 1 and FIG. 5 is a sectional view taken substantially along the line 5-5 of FIG. 2.

Numeral 10 represents the brush portion of a paint brush shown exploded in FIG. 1, the handle part being indicated generally by the numeral 12.

The brush portion comprises a body of bristles 15 which may be set at their extremities in a suitable binder within a ferrule 18 of brass or other suitable sheet metal. It will be understood that the brush portion 10 may be of standard or other suitable form and the ferrule 18 may be provided with a plurality of holes 20 for convenient attachment to the handle; if desired, these holes may be formed at the time of attachment, as by means of brads, rivets, etc.

The improved handle formed in accordance with my invention is preferably hollow and molded of a suitable synthetic plastic, such as nylon, a phenol-formaldehyde resin, etc., hard rubber or other suitable material having the desired characteristics of rigidity, hardness, etc. The handle portion 12 comprises an elongated grip element or stem 22 and a ferrule-engaging sleeve-like portion 25. Portion 25 is so proportioned as to seat snugly within the ferrule 18 and is connected to the grip portion 22 by means of a tapered intermediate neck portion 28 having a continuous shoulder portion 30 engaging the free edge of ferrule 18. I

Formed integrally in the handle portion 12 is a plurality of lugs or bridges 35 extending in a transverse direction between and connected to opposite sides of ferrule-engaging portion 25, said lugs being of appreciable width, i.e., having appreciable dimension in a direction across said ferrule-engaging portion perpendicular to said transverse direction, and having their bases integrally connected to neck portion 28 as indicated at 29 in FIG. 2. In the instant case I have shown two bridges 35, but it willbe understood that the number may be varied. Two will ordinarily be sufficient for my purposes.

In view of the relative hardness of the plastic materials suitabe for my purpose it is preferable that perforations 38 be formed in the bridges 35 at the time of molding the handle portion 12 for the reception of fastening elements such as brads or rivets. These perforations, as seen in FIG. 5, may extend entirely through the bridges 35 or may extend only a relatively short distance from the surface of the bridge into the interior thereof, of sufiicient depth to receive a fastening element. Because of the appreciable width of the lugs 35, the placement of perforations therein is not a precision operation and the brads or rivets which are inserted therein interconnect the handle and brush effectively and securely without possibility of fracture or cracking.

Also preferably molded integrally with the handle is a plurality of webs 39 extending transversely of the sleeve 25. Ordinarily, as shown in FIGS. 2 and 3, a single pair of such transverse webs 39 will be adequate. They are preferably positioned substantially in line with or in continuation of side walls of the stem portion 22 of the handle, or may be positioned laterally of the projected sides of the stem portion.

It will also be noted that the free edges of webs 39 are substantially flush with the bottom edge of sleeve 25.

These Webs 39 perform several functions. They serve not only to reinforce sleeve portion 25 but also perform an additional important function. If the brush is dipped into a body of paint to such depth that the ferrule will be submerged, there is a tendency for the liquid to seep past the ferrule and into the handle. Webs 39 serve effectively to prevent such liquid from flowing into the stern portion 22 of the handle; thus the brush remains light in weight and properly balanced at all times and under all conditions.

In the assembly of my improved brush it is merely necessary to pass the ferrule 18 over the seeve 25 of the handle portion until the edge of the ferrule engages shoulder 30, whereupon brads or rivets 40 will be driven through the ferrule and into the bridges 35. Thus, it will be seen that the assembly operation is extremely simple, may be quickly accomplished by relatively unskilled labor and results in a rugged brush assembly having a light-weight and attractive handle.

Various changes coming within the spirit of my invention may suggest themselves to those skilled in the art; hence, I do not Wish to be limited to the specific embodiments shown and described or uses mentioned, but intend the same to be merely exemplary, the scope of my invention being limited only by the appended claims.
