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.
