Application liled September 20, 1887. Serial No. 250,171. (No model.)
To all whom it may concern,.-
Be it known that I, LOUIS W. NIMscHKE, of the city, county, and State of New York, have invented certain new and useful lmprovements in the Manufacture of Brushes, of which the following is a specification.
This invention relates to certain improvements in the manufacture of hair and other` brushes; and the invention consists of a brush of novel construction, as will appear more fully hereinafter, and finally be pointed out in the claim.
In. the accompanying drawings, Figures 1 and 3 represent averticallongitudinal section of the mold employed for filling the baseplate of the brush with bristles. Fig. 2 is a top view of the bristle-hoiding'rbase-plate. Fig. 3 is a vertical longitudinal section' of a modified form of the filling-mold, and Fig; 4 is a vertical longitudinal section of the brushbase attached to a brush-back.
Similar letters of reference indicate corresponding parts.
In the drawings, A -represents a bristleholding base-plate, which forms the novel feature of myimproved brush, and which is made of brass, tin, or other suitable soft metal, and of the shape and size of the brush to be manufactured. The base-plate A is provided wit-h anumber of bent-up points or prongs, af, which are made integral with the body of the baseplate and set into correspondingly-arranged 'socket-holes of the base-block B of the mold- B. The base-block B is provided with vertical guide-pins b b, that are screwed into said block, said pins serving to guide the filling top block, B2, of the mold B. The base-plate A is provided with a vnumber of perforations, d, which are provided with conically-tapering rims d', that project either from the under side or from the top of the base-plate A, as shown, respectively, in Figs. 1 and 3. The top block, B2, of the mold B is provided with as many holes as there are perforations in the base-plate A, said holes serving for the purpose of filling the rimmed perforations d of the base-plate A with bristles. The baseblock B is provided vertically below and in line with the fillin g-holes of the top block, and the perforations of the base-plate with conically-tapering depressions d2, of such a na-I j ture that the inclination of their tapering sides is somewhat steeper than the inclination of the tapering rims, so that on lowering the top block, B2, by suitable pressure exerted thereon, the tapering rims of the base-plate A are contracted at their edges by the depressions of the base-block, and thereby the tufts of bristles that have been filled through 'the holes of the top block retained firmly by the contracted rims o f the base-plate A. This arrangement is shown in Fig. 1, in which case base-plates are produced in which the tapering rims project at the under side of the plate and bind rigidly on the lower ends of the tufts. In place of arranging the tapering depressions on the base-block, they may also be arranged at the lower ends of the fillingholesof the top block, B2, as shown in Fig.
3, which arrangement is used when the tapering rims project from the upper partof the base-plate, as shown in Fig. 3. Inthis case the inclined sides of the tapering de-l pressions` are arranged at a smaller angle of inclination to the axis of the filling-holes than the outer tapering surfaces of the rims to the axis of the perforations of the base-plate A, so that on depressing the top block, B2, by suitable pressure, the edges of the tapering rims are contracted and closed tightly on the tufts of the bristles supplied through the openings of the top block, B2, to the rimmed perforations of the base-plate A. The base-plate Awith the tufts,`is then removed from the lling-mold and applied by the spurs a a and a suitable layer of cement to a back, C, vof wood, rubber, or other suitable material, which back extends around the base-plate, the rim of the brush-back being ilush with the face of the base-plate when the construction shown in Fig. 1 is used, while in the construction of the base-plate shown in Fig. 3 the tapering and contracted bristle-holding rims project above the face of the back.
This method of constructingbrushes is adapted to 'all kinds of brushes-such as hairbrushes, clothes brushes, blacking brushes, &c.-and produces a cheap, strong, and durable brush, as the bristle-holding base-plate can be cheaply made of suitable cast metal, or pressed in dies when metal of suflicient ductability and softness is employed.
