4 Claims.

This invention relates to brushes and more particularly to hair brushes and the like.

A primary object is the provision of a device of this kind in which the bristles and their mounting may be removed in several units from the back of the brush and from the handle there- It is a further object to provide a brush in which units forming parts of the brush may be renewed and replaced when worn.

It is another object to provide a brush in which the bristles may be arranged to form a curved surface for cleaning cavities. I 7

It is also an object to provide a brush, the bristles of which may be easily cleaned and sterilized.

With these and other objects in view, the invention consists in certain novel features of construction, combinations and arrangement of parts which will become clearer from the following description and the accompanying drawing in which- Fig. l is a front view of a brush embodying the invention.

Fig. 2 is a side view thereof.

Fig. 3 is asectional View on. line 3-3 of Fig. 1.

Fig. 4 is a sectional detail view on line 4-4 of Fig. 2.

Fig. 5 is a view illustrating the rolling action of the curved surface of the brush in use.

Fig. 6 is an end view showing a modified form of brush frame.

Referring to the drawing, in represents the back or frame of the brush which may be made of any suitable material but preferably of phenolic compound. A handle I I is attached to back II) or formed integrally therewith. n the opposite ends of back 10 are plates l2 and I3 which may be integrally, formed or may be separately formed. These plates extend perpendicular to the back ID to form brackets.

Three cylindrical brushes [4, l5, and I6 are mounted between brackets l2 and I3 parallel to each other and to back l0. Each brush consists of a stem l1 formed of a pair of twisted wires and each stem extends a distance beyond both ends of the brush. The stems I! of the brushes are slightly shorter than the distance between brackets I Z'and l3. Bracket I3 is. provided with three apertures l8 on its inner side, each of which apertures accommodates one end of the stem. Bracket I2 has three screw-tapped apertures in alignment with those of bracket l3 in each of which a slotted screw 19 is mounted, each screw having an axial aperture 20 in its interior end to accommodate the opposite end of the stem I1.

When the apertures l8 and 20 are so spaced that the distance between the apertures in the same bracket is larger than the diameter of each brush, the brushes may rotate in. these apertures when screws l9 are not tied against the ends of stems ll. In the drawing however a brush is shown in which the distance between apertures l8 and 20 is shown to be shorter than the diam- 10 eter of the three brushes in which case the bristles of each two brushes interfere with each other and prevent rotation.

In order to remove any one of the brushes from the supporting frame, it is only necessary to unscrew the holding screw in bracket l2 until its front end is within said bracket when the stem ll of that brush may be disengaged from aperture l8 and the brush removed from its frame.

By reason of the foregoing construction, provision is made for cleaning or sterilizing any one of the brushes separately, for renewing it with a duplicate brush, or all three brushes may be replaced when worn at very small expense and the expense of a new frame may be saved.

The three brushes may of course be used for purposes other than for brushing hair and may be used on convex as well as concave surfaces by joining brackets l2 and I3 by means of bars 2| as shown in Fig. 6, in which form the bristles may rotate and be used for cleaning convex and concave surfaces, and in which form the back I0 is eliminated. In similar manner, the three brushes may be arranged in a common plane for brushing flat surfaces.

It will be understood that modifications may be made in the details of construction of the above described brush without departing from the principle of the invention, and it is desired to be limited only by the state of the prior art and the appended claims.

I claim:

1. A brush comprising a frame having a pair of spaced brackets thereon extending perpendicularly from one face of said frame, a plurality of brushes, each brush having a central stem and bristles held thereon, each stem extending beyond said bristles, one of said brackets having apertures for holding one end of each stem and means on the other bracket in axial alignment with each stem pressing against the end of the stem for clamping it against rotation.

2. A brush. comprising a back, a pair of spaced brackets on said back perpendicular thereto, a plurality of twisted wire brushes having axial stems in the space between said brackets, one end of each stem being rotatably mounted in an aperture of one of said brackets, the opposite end of each stem being held in an axial aperture of a clamping screw on the other bracket.

3. A multiple unit brush comprising a plurality of units, each having bristles held between a pair of twisted Wires forming an axial stem protruding beyond the bristles at each end, a frame mounting said units longitudinally parallel to each other and transversely in triangular formation for rotary motion and means on said frame to prevent said rotary motion by pressing against the end face of each stem.

4. A multiple unit brush comprising a frame,

an integral flange portion at each end of the frame forming a bracket, spaced grooves in one flange, spaced openings in the other flange in alignment with the grooves, brush units positioned between the flanges, each unit having a central stem formed of twisted wires and bristles therebetween, each stem having ends protruding beyond the bristles, adjustable and movable screws mounted in the bracket openings, one end of each stem being inserted in the groove in the bracket and its opposite end being supported by one of the adjustable screws whereby the brush unit is clamped to the frame.
