MANUFACTURE OF BRUSHES.

SPECIFICATION forming part of Letters Patent No. 788,904, dated May 2, 1905.

Application filed Novemher17, 1904. Serial No. 233,116.

- To all whom, it may concern:

Be it known that I, WILLIAM HERBERT, Jr. of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in the Manufacture of Brushes, of which the following is a specification.

This invention relates to a brush composed of a bunch of bristles, the bases of which are cemented together by vulcanized rubber or otherwise.

The invention has for its object to provide improved means for attaching a bunch of bristles to a handle in such manner as to furnish a strong, durable, and relatively inexpensive brush.

The invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a sectional view of a bunch of bristles united at their bases and provided with a handle-engaging device in accordance with my invention. Fig. 2- represents a sectional view of a portion of the brush-handle which engages the said handle-engaging device. Fig. 3 rep- I resents a sectional view showing the said handle portion engaged with the handle-engaging device. Fig. 4 represents a sectional view of the brush and its handle connected in accordance with my invention.

The same reference characters indicate the same parts in all the figures.

In the drawings, (t represents a bunch of bristles of suitable form for a brush. The base of said hunch is provided with a filling a, of rubber, which is applied by saturating the base of the bunch with a solution of unvulcanized rubber or rubber cement and subsequently vulcanizing said filling to solidify it and cause it to adhere to the bristles. The said filling is indicated by the shaded portions in the drawings. Before the rubber is vul canized a metallic ferrule 7) is applied to the base of the bunch, said ferrule surrounding and closely confining the base and being provided with a coupling member which consists of an outwardly-projecting flange I), having its outer edge turned downward. The vulcanization of the rubber filling unites the ferrule firmly to the base of the brush, owing to the adhesion of the rubber to the inner surface of the ferrule as well as to the bristles.

0 represents a brush-handle, which is provided with a coupling member adapted to engage the coupling member of the brush-ferrule Z). The coupling member on the handle consists of an inwardly-projecting flange 0', having its inner edge turned upward, said flange being formed on a metallic ferrule 0 which is adapted to embrace one end of the handle. The flange c is formed to be interlocked with the flange Z) of the brush-ferrule, as shown in Figs. 3 and 4. The handle-ferrule c is preferably interlocked with the brush-;

ferrule before the handle-ferrule is attached to the handle 0, the handle being then inserted in the ferrule and abutted against the brushferrule b, after which the handle may be socured by nails 0 or otherwise. The handle thus secured holds the flanges 6 c in engagement with each other. When the lower surface of the handle 0 is abut'ted against the upper curved edge of the flange b of the brushferrule, the downward-turned outer edge of said flange is firmly and permanently interlocked with the upwardly-turned inner edge of the flange 0, whereby disengagement of the two interlocked or coupled members is prevented simply by the lower surface of the handle 0; but the brush and its ferrule can be readily separated from the ferrule 0 whenever the nails 0 or other fastening devices are removed.

The flrm union between the bristles and the metallic brush-ferrule I), caused by the vulcanization of the rubber filling, insures a strong and durable connection between the bristles and the handle, the metallic ferrule being also strong and durable.

I do not limit myself to a brush the bristles of which are united by vulcanizedrubber. Any other suitable cement may be used to unite the bristles at the base of the brush and to unite the base of the brush to the brush-ferrule I).

I claim- A brush comprising a bunch of bristles, a metallic brush-ferrule embracing the base of the bristles and having its upper edge turned outwardly and downwardly, and a handlehav- In testimony whereof I have affixed mysiginga liialrruledthe lowe'ledge of which is turned nature in presence of two witnesses.
