2 Claims.

This invention relates to brushes and more particularly to hair brushes in which the brush part is renewable and in which the bristles may easily and conveniently be cleaned. I

It is an object of this invention to provide a brush which has the above advantages and is rigid and simple in construction and which may easily be taken apart for cleaning and in which the bristles may be renewed when worn out by replacing one or the other Worn brush.

With these. and other objects in view which will appear more clearly as the description proceeds, the invention consists in the novel construction, adaptation and arrangement of parts hereinafter described and illustrated in the accompanying drawing, in which Fig. 1 is a perspective view of my new brush.

Fig. 2 is a side elevation of the brush.

Fig. 3 is a sectional elevation on the plane of the line 3--3 of Fig. 2.

Fig. 4 is a sectional elevation on the plane of the line 4-4 of Fig, 2.

Fig. 5 is a sectional elevation on the plane of the line 5--5 of Fig. 2.

Fig. 6 is a view of one of the removable brushes.

Referring to the drawing, a brush handle it) is provided with a plate II preferably integral therewith and forming an elongation of the handle and parallel to the handle-axis and offset thereto by means of a transverse plate I2. A similar transverse plate I3 forms the end of the brush opposite the handle I0.

The handle I0 with plates II, I2 and I3 is preferably made of aluminum, plastic moldable compound, wood or other suitable material. The bristles forming the brush are preferably entwisted between three separate pairs of metallic hair .wires which form the stems for the cylindrical brushes I4, I5 and I6, which protrudes at either end of the brushes for a short distance I to, I5a and Ilia as shown in Fig. 6. The ends I2:r, I330 and Ma: of the three cylindrical brushes are mounted in cylindrical apertures on the inside face of plate I2 (see Fig. 5). The opposite ends of stems I4e, I5e and I6e are inserted into corresponding oppositely located circular apertures in the inside face of transverse plate I3 by sliding them when the stem is slightly shortened in length (by bending it as shown in Fig. 1) through thehorizontal groove Ma and vertical groove I31) into aperture I3ba, and in a similar manner the stem I56 with brush I5 is inserted through grooves E311 and I30 into aperture lilca, the last brush stem end Hie of course being inserted in the same manner into aperture I3da. When the stem ends have reached their final positions opposite their respective apertures in plate I3 the pressure for bending them is released and they slide a short distance into these apertures locking the brush in the desired position.

In this simple manner a very useful hair brush which can be made and sold for a Very reasonable price has been made and is offered to the public.

It is of course possible to make changes in the details of construction without departing from the invention and I therefore desire to be limited only by the state of the prior art and the appended claims.

I claim:

1. A hair brush forming a curved brushing surface consisting of a plurality of cylindrical brushes each brush having a stem consisting of a pair of resilient metallic wires and bristles entwisted therebetween, the stems of said brushes being arranged in triangular formation parallel to an elongated plate having transverse ledges at its ends with an entrance slot in one ledge and oppositely aligned apertures on the inside of said ledges holding the ends of said stems so that the outline of the bristles thereon forms a curved surface.

2. A hair brush comprising a c oncavo-convexo shaped back portion, an inwardly extending ledge portion at each end of the back portion, each ledge portion being formed with openings in opposed relationship to the other ledge and one of said ledges being formed with a transverse slot communicating with its respective openings, a plurality of brush members detachably supported between said ledges, each brush member including awire stem with its ends in said oppose openings and bristles on the wire stem.
