IMPROVEMENT IN BRUSHES.

Specification forming part of Letters Patent No. 222,166, dated December 2, 1879; application filed September 16, 1879.

To all whom it may concern:

Beit known that we, GEORGE WADSWORTH, of Boston, in the county of Suffolk and State of Massachusetts, and JOSEPH B. SMITH, of New York, in the county and State of New York, have invented a new and useful Improvement in Brushes, of which the following is a specification.

Our invention relates to an improvement in the class of bristle-brushes such as are used for painting, whitewashing, &c.; and it consists in the construction and arrangement of parts as hereinafter described, whereby the bristles are firmly secured to the stock or head, and a superior brush produced economically.

- It consists in providing the stock with a dovetailed core, along which the butts of the bristles are-laid and secured by wooden strips oneach side held under a metal ferrule .securely fastened to the core outside of the bristles.

In the accompanying drawings, Figure 1 is a sectional side elevation of my improvement in brushes, and Fig. 2 is a vertical cross-section of Fig. 1 on linear .00.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A is the fiat stock of the brush provided with a handle, B, and having on its bottom edge a dovetailed projection, O, forming the core. Above the shoulders to a grooves 12 are made in the sides of the stock.

D is the ferrule made in two parts, which hence may be easily and quickly attached or detached. This facility of attachment and detachment, coupled with the facts that the core 0 does not require to be perforated nor the bristles to be secured thus by means of nails orcord, greatly economizes the labor of constructing the brush as compared with others of its class. I

Lips d are formed on the lower edges of the plates D, which, together with the angular lateral projection of the core 0, hold the strips E in place.

The upper edges of the sides of the ferrule are turned over inwardly at right angles, forming flanges e c, which are adapted to be fitted into the grooves 11 b. A head or rib, f, is struck outwardly in the sides of the ferrule to give stiffness to the sides.

The manner of operating our invention is as follows: The butts of the bristles E are laid along the sides of the dovetailed projection O and aronndzthe ends t-hereof,'with their extreme ends abutted against the shoulders a, as shown in the drawings. \Vhen they have been laid into the proper thickness the ferrule is put in place with the wooden strips against the bristles, and the lips d compressing the bristles against the broad edges of the dovetail, and the flanges c e in the grooves b, and when the two parts of the ferrule have been pressed up against the bristles with sufficient force, the ends are joined together and nailed to the core, as before described.

By the construction and arrangement of parts above described, we produce cheaply a brush whose bristles are held very securely by the coaction of the angles of the core 0, the elastic metallic plates D and elastic wooden strips E;

We do .not claim, broadly, the use of elastic 1netallic plates for this purpose, and we are aware a brush has been provided with a core having inclined sides, but, not with the acute angle of ours. I I

Having thus described our invention, W

claim as new and desire to secure by Letters Iatent In a brush, the combination, with the wooden core G, having an acute angle at its lower edge, oi the elastic metallic side plates, D D, constituting the ferrule, and the wooden strips E E, which are placed between said plates and core, as shown and described, for the purposespecilied.
