Claims



Having described my invention, I claim:

1. A hair brush having a head portion, and set therein a plurality of pairs of bristles, substantially evenly distributed over said head portion, the bristles in each pair being of two different lengths, each pair of bristles being constituted by a single strand of material, folded upon itself about a point spaced from the mid-point of said strand, thus producing an equal number of short and long bristles, said head portion having said pairs of bristles individually fastened thereto.
Description



Hair brushes are available in a large number of varieties with widely differing bristle faces and with bristles of varying lengths in the different parts of the bristle face, e.g. with long bristles at the ends, and short bristles in the middle part. The purpose is that the curvature of the bristle face shall approximately fit the shape of the head.

The known brushes are, however, not very suitable for the brushing of wigs, in that they have only small ability to penetrate into the hair body, and therefore only work on the surface and in the outer regions. Brushing of the wig therefore becomes very prolonged if a satisfactory result is to be obtained, and the wear on the wig becomes unnecessary great, especially on "double hair" wigs.

The purpose of the invention is to provide a hair brush which performs far more satisfactorily than previously known brushes, in that the ability to penetrate into the hair body of a wig is increased significantly, a result which is obtained by making a part of the bristle significantly longer than the remaining bristle and setting pairs of long and short bristles evenly distributed over the bristle face.

The longer bristles will then act as a hair brush which has few and scattered bristles which will easily penetrate into the hair body, while the bristle face with the shorter bristles will work as a brush with more bristles, together with the long ones which are active on the surface and in the surface layers of the hair body.

Thus the invention concerns a brush having bristles set in pairs, the bristles in each pair being of different lengths.

Other features and details will be evident from the following description and drawing, where:

FIG. 1 shows a brush according to the invention, seen in perspective,

FIG. 2 shows a side view of the same brush, and

FIG. 3 shows an end view of the brush.

The brush has an ordinary head 1, with a handle 2, and the bristle face is formed by long bristles 3 which are evenly distributed over the brush head, and shorter bristles 4 which are likewise evenly distributed. The bristles are set together in pairs, where one bristle in the pair is long and the other is short. This facilitates production because a long strand may be folded over about a point which is at a distance from the middle point, so that the two portions will have different lengths. This double bristle may then be fastened in holes 5 by usual methods.

The example shown serves only to illustrate the invention, and other versions falling within the scope of the invention may be envisaged. As an example the bristles may end in more than two levels, resulting in a brush having the bristles of varying density at various levels of the bristle face.
