UNITED STATES PATENT OFFICE PAINT BRUSH FERRULE Marlon F. Kowalski, Jamaica, N. Y. Application August 16, 1944, Serial No. 549,744

2 Claims.

This invention relates to ferrules for paint brushes and is particularly directed to an improved means for effectively retaining the edge portions of the ferrule in overlapped relation so as to secure together the handle and bristle body members in permanently associated relation.

Heretofore, the opposite edge portions of paint brush ferrules have been secured together in a variety of ways such as by a so called lock seam, by rivets, by solder, by spot welding or a combination thereof but have been found open-to the objection that after limited use, the moisture of the paint, calcimine or other substance applied by the brush causes the swelling or expansion of th'e handle and bristle setting resulting in opening up of the ferrule seam and the falling apart of the brush.

In order to overcome the above noted objection, the present invention broadly comprehends an improved ierrule joint which dispenses with soldering, riveting or spot welding operations and which is so constructed and arranged as to pre clude any possibility of the opening up of th'e seam or joint, while more specifically the invention contemplates a permanent joint which embodies a series of mating nested bights stamped or otherwise formed in the overlapped edge portions of the ferrule for receiving therethrough a flat lock wire or metal strap and which' bights and wire or strap, when assembled, are hammered and thus distorted so as to prevent accidental or unintentional displacement of the lock Wire or strap.

With the above recited and other objects in view, the invention is set forth in greater detail in the following specication, particularly pointed out in the appended claims and illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective veW of a paint brush embodying a. ferrule constructed in accordance with the present invention.

Fig. 2 is an enlarged fragmentary sectional plan view taken approximately on the line 2-2 of Fig. 1.

Fig. 3 is an enlarged fragmentary vertical sectional view taken approximately on the line 3-3 of Fig. 2, illustrating some of the bights and a portion of the lock wire distorted after hammering.

Referring to the drawing by characters of ref-V erence, A designates the h'andle of a paint brush which is preferably constructed of wood andB indicates the bristle body member composed of a plurality of bristles adhered together adjacent their upper by a suitable adhesive or cement.

The ferrule C which constitutes the present invention is preferably fashioned from sh'eet metal into the form of a band which is adapted to be snugly fitted into surrounding relation to the base or shank portion of the handle A and the upper adhesively connected end 4of the bristle body member B, with the inner and outer end portions I0 and II of said sheet or band disposed in overlapping relation to form a tubular structure corresponding approximately to the cross-sectional size and shape of the lower base or shank portion of the handle A and the upper end portion of the bristle body member B.

The overlapping end portions II'I and II of the ferrule C are provided with a plurality of longitudinally spaced transverse parallel registering slits, the material therebetween being alternately offset inwardly and outwardly to provide bights or loops I2 and I3. The inwardly offset bights or loops I2 of the inner edge portion I0 are designed to nest, mate or interflt with those of the outer edge portion II, while the outwardly offsetbights or loops I3 of said inner overlapping edge portion Il) are likewise fashioned to nest, mate or interfit with those of the outer edge portion so that, when thus nested, adjacent alternate pairs of inwardly and outwardly offset bights I 2 and I3 define a series of loops or a linear passageway for receiving a retaining element in the form of a at wire or metallic strap I4 which electively locks the overlapping inner and outerA end portions I0 and I I of the ierrule C and precludes relative separation thereof in any direction.

After the retaining wire or strap I4 has been inserted and severed so that the opposite ends thereof are substantially flush' with the outer side edges of the endmost bights or loops I3, the said bightsv or loops are hammered or pressed to such an extent as to flatten the same thereby crimping the retaining element longitudinally, as illustrated in Fig. 3 th'us preventing accidental clisplacement of the same by axial movement thereof with reference to the bights or loops.

What is claimed is:

1. In a brush, a handle member, a bristle body member and means for connecting said members consisting of a ferrule fashioned from sheet material having overlapped edge portions formed with mating nested alternating inwardly and outwardly oiTset bights dening a linear passageway, and a retaining element extending through said passageway with the outwardly offset bights disposed outside of the retaining element and the inwardly oiset bights disposed inside of said retaining element, said bights and retaining elelength of sheet material folded upon itself with 5 the edge portions thereof overlapped and cut bent and formed to provide a series of mating nested inwardly and outwardly oiset bights 1ocated in a direction transversely of the edge portions, and a retaining element reaved through and disposed between the inwardly and outwardly oiset bights, said bights being distorted toward each other on the retaining element to crimp said element for preventing its displacement from th'e bights.
