BRUSH.

Application filed July 19, 1886.

it may concrn:

that I, HERBERT E. FOWLER, in the eounty of New Haven and State of Connecticut, have invented a new Improvement in Brushes; and I do hereby declare the following, when taken in connection with accoinpanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, iii- Figure 1, a perspective View, looking upon the face of the brush; Fig. 2, a transverse section of the same; Fig. 3, a longitudinal section of the same through one of the grooves; Fig. 45, a perspective view of the wire and fbers interwoven preparatory to introduction to the block. Figs. and G illustrate methods interweaving the fibers and wire; ig. 7, modification of the groovcs in the block.

This inveution relates to an improvencntin that class of brushes in which the bristles are usually set in blocks-such as tcoth-brushes, hair brushes, blacking brushes, scrubbing brushes, and the like. In the more general Construction of this class of brushes the block is drilled with a separate hole for each tui't and each tuft requires independent fastening.

The object of my inveution is to reduce the cost of setting and not more durable than the common tuft brushes; and the invention consists in interweaving the fibers with a continuous wire, theu setting the wire in the requiste lengths in the grooves in the brush-block, as

more ully hereinafter described.

-In prepari ng the bristles or fibers for ap plication to the back, I twist together two strands of wire, a a, Fig. et, and in the process of twisting interweave the fibers by doubling the fiber around one or both wires, as seen in Fig. 5, or placing them between wires, as seen in wires the fiber is mit the wire to pass into the groove block, and the bring the fibers into .To all whom,

Be it known doubled sufficiently to perof th their proper relative position, making the succession of fibers substantially continuous. The wire thus filled with fiber is ready for the block.

make the brush equally if twistof the Then in twisting the e sides of the groove in the block part of Letters Patent No. 359.250, clated March 15, 1887.

Serial No. 20836. (Ne model.)

The block A is ,constructed with grooves b, preferably undercut, and of a diameter somewhat greater than the diameter of the twisted wire and fiber, but in width so that the wire may be drawn through the grooves. is cut in the rcquisite lengths and the grooves, as rcpresented in Fig. 2.

i overhanging part of the groove may be sufllcient to hold the wire and fibers firmly. The

l fibers extend from the groove and naturally spread, so as to present a solid fiber surface,

i as shown. may be, as seen in Fig. 7, of eq and the wire intro- 'glue or similar cement to embed i the wire and secure it in place. The groove may be longitudinal, as represented in Fig.

1, or of any desirable shape, according` to the style or character of the brush. By this coustruction the fibers are very rapidly prepared in long continuous runs ot' wire read cut. These may be produced by hand;

` propose to combine the wire and fiber by a machine which will constitute the subject oi' an independent application for patent.

l ter the fibers have been set the face ofthe brush In this Construction of brush there is no liability of the iibers becoming detached, asin many brushes in which the fibers are set, in

tufts, and the brush is chcaply produced and of the most durable character. g

VVhileIprefer to make the strands with which the fibers are interwoven from wire,

'r cheap and strong, it

R will be understood that other material may be 5 used for the strands -such, for illustration, as a strong twine.

i I claim* The herein-described improvementin brushi es, consisting in twisted strands having fibers go interwoven therewith, and so as to project therefrom, and a block constructed with one or more grooves, into which the said twisted strands holding the fibers are set, substantially as described.
