' IMPROVEMENT IN BRUSHES.

Specication forming part of Letters Patent No. 121,050, dated November 21, 1871.

To all whom it may concern:

Be it known that I, HAYWARD A. HARVEY, of Orange, in the county of Essex and State of New Jersey, have invented certain Improvements in Brushes, of which the following is a specification:

method of holding a loop of bristles or any suitable iibers in the form of a tuft; and the sec` ond part of my invention relates to a mode` of holding tufts of bristles or fibers in brush-` stocks. Y l

In the drawing, Figure l is an elevation of the tuft; Fig. 2, a section of the same throught` line x, Fig. 1; Fig. 3, a perspective view of the ferrule; Figsf/i, 5, and 6, views of corrugated ferrules inserted in brush-stock, the bristles being removed.

The first part of my invention is an improvement in the construction of that class of tufts in which metallic ferrules are used for encircling a loop of bristles or fibers; and consists in compressing, pinching, or indenting portions of thev periphery of the ferrule into the middle or eye of the loop, thus making the end of the i'errule resemble in appearance the figure S. An effect similar to this has been attempted to be produced heretofore by the introduction of a wire staple into the loop below the ferrule or eyelet; the object of the wire staple being, mainly, to act as a key in preventing the withdrawal of theA loop of bristles from the ferrule, and, incidentally, to compress or crush in the periphery of the ferrule by the impact of the legs of the staple thereupon when the tuft is pressed into its seat in the brush-stock. This latter action of the staple is partial and uncertain, because the Wood of the brush-stock yields more or less, and the legs of the staple partially embed themselves into that. I therefore describe this branch of my invention as' an improvement in the construction of tufts, as aforesaid, because I produce a positive and exact result by forcibly compressing or indenting the periphery of the ferrule into the loop prior to its insertion into the stock, and am thereby enabled to dispense with the wire staple altogether. I not only do not require the wire staple for the purpose of compressing or crushing in the periph- 'ery of the ferrule, but the positively-indented periphery of my ferrule exercises substantially the function of the wire staple in acting as a key to prevent the withdrawal of the loop of bristles. The first part of my invention relates to al I am aware that it has been proposed to construct a ferrule for this purpose with small points or projections 011 its inner end, which can be bent over into the loop of bristles so as to act as a key; but my invention is much more simple, inexpensive, and practical than this, being applicable to ferrules or eyelets of ordinary form.

Figs. 1 and 2 exhibit my improved methodof holding the loop of bristles in combination with a flanged ferrule or eyelet. The purpose of the ange is to secure the tuft in the brush-stock in the manner heretofore practiced, to wit, by its expansion under pressure, so as to fill a cylindrical recess in the stock, as more particularly described in the Letters Patent of the United States heretofore granted to C. D. Rogers and M. I). Wilkins for an improved method of holding bristles in brush-stocks, and bearing date the 29th day of October, 1867.

The second part of my invention consists in corrugating more or less of the outer surface or periphery of the fer-rule used for holding brisvtles, so that when the ferrule is forced into a pression, or inequalities in the exterior surface of the ferrule may be produced by cutting entirely through the periphery, as shown in Fig. 5

at i.
