Application April 6, 1940, Serial No. 328,193 4 Claims. (Cl.'13285) This invention relates to the combination of a comb and removable brushes therefor whereby the brushes are individually and easily removable from their supports on the comb.

An object of this invention is to provide simply constructed supports on the comb which may be either separate or parts but permanently joined to the comb or integrally cast with the comb.

Another object of this invention is toprovide demountable brushes on a comb whereby they may be individually removed without in any way disturbing the mounting of the other brush.

A further object of this invention is to provide a demountable brush construction for a comb whereby the brushes react against the comb and function to seat themselves firmly in the sockets inwhich they are mounted. By merely pressing the brush against the comb it can be removed easily from its sockets. When in use, however, the brushes do not accidently slip from their mountings.

A more specific object of this invention is to provide removable circular cross-section brushes for a comb brush combination in which the distance of the brush mounting supports from the comb is less than the radius of the circular crosssection of the brush. Thus, when mounted, there is always a resilient action caused by the bristles of the brush pressing against the ,comb which tends to retain it in its supports.

A'further object of this invention is to provide a demountable brush for a comb which has spring mountings therefor whereby the brush may snap into position and be retained therein.

The above and other objects and advantages of this invention will become apparent as the description proceeds, reference being had to the accompanying drawing wherein:

Figure 1 is a side elevation of a combination hair curler, comb and demountable brush construction of this invention;

Fig. 2 is a top plan view of Figure 1;

Fig. 3 is an end elevation of Figure 1;

Fig. 4 is a side elevation of a comb with a demountable brush showing a modification of the supports for the brushes;

Fig. 5 is a sectional view on the line 5-5 of Fig. 4; and

Fig. 6 is another modification of the brush mountings.

Referring to Figures 1 to 3, the comb generally indicated by the numeral I0, is shown as a combination hair curler and comb of the type foldable like a jackknife in which the curler functions as a sheath for the comb when in the folded position. The hair curler II is pivoted at I! and may be swung from the open position shown in dot-dash lines tcy a completely closed position (not shown); A small piece of spring metal 13 is embedded in the comb and functions to retain the curler in-open position. -When in open position the curler may be used as such or'it may be used as a handle for the comb.

Referring to Figures 1 to 3, the comb has the usual back It and teeth l5. At each end of the comb firmly joined to the back are lugs l6 extending out from each face of the comb at each end. The two lugs of the comb at each end may be formed of one piece of metal extending through openings through the back of the comb and locked therein in any known manner, as by a force fit. This is shown on Figures 1 to 3; or

each lug may be individually attached to the backof the comb, as by rivets, or in any other known manner. The lugs may be made of any suitable material such as metal and preferably a material having some degree of springiness.

The lugs it have turned down ears which provide the bearing supports I! for the brushes as will be explained below. y

The brushes I9 employed in the present comb brush combination are any usual type having a circular cross-section. In the illustration shown they are made by spirally winding a plurality of wires forming a core which have bristles placed between them. The ends of the wire core extend slightly beyond each end of the brush and these extending ends provide journals I8 which support the brushes in the bearings l1.

The distance of the bearings I! from the comb is made smaller than the radius of the circular brushes. This is done for the 'very definite purpose of compressing. the bristles which come into contact with the comb. Thus the reaction of the bristles will be to force the brush firmly into its supports l1 and retain it in position firmly yet resiliently. In order to remove the brush it is merely pressed towards the comb and it may then be readily slipped down out of its sockets.

- Nothing more positive is required to retain the brushes in position on the comb than the reaction of the bristles against the comb. When in a use the pressure inward against the brushes is never great enough to dislodge them. Furthermore, such pressure is mostly upwards against the lugs l6 and only slightly inwards against the comb.

Figs. 4 and 5 show a modification of the construction of the supporting lugs relative to the comb. The comb in this illustration does not fold. It has a handle 20 and lugs 2| which are preferably cast or otherwise formed integrally with the comb. These lugs would probably be cast straight and then bent around to form the bearing supports for the brushes. As in Figs. 1 to 3, the distance from the center of the bearings formed by the lugs to the comb is less than the radius 01' the brush.

Figure 6 shows another modification in which the turned down bearings i1 01 Figs. 1 to 3 are bent up and then back as shown by numerals 22 to provide resistance knobs past which the brushes must be snapped in order to be received in their bearings. Thus, besides the action of the bristles which tend to retain the brushes in their bearings there is the added spring action of the metal of the lugs and the resistance knobs which will prevent dislodgment of the brushes.

I do not wish to be limited by the exact details of construction as shown, but all equivalents as may fall within the scope of the appended claims are meant to be included.

I claim:

1. A comb-brush comprising a brush having a core and radially extending bristles, and a comb having hook-like lugs projecting laterally from its back a distance less than the length or the bristles, the ends of the brush core being inserted in the lugs and demountably held therein by pressure of the bristles against the comb.

2. A comb-brush comprising a brush having a core and radially extending bristles, and a comb having integral hook-like lugs projecting laterally irom its back a distance less than the length 01' the bristles, the ends of the brush core being inserted in the lugs and demountably held therein by pressure of the bristles against the comb.

3. A comb-brush comprising a brush having a core and radially extending bristles, and a comb having resilient hook-like lugs projecting laterally from its back a distance less than the length of the bristles, the ends of the brush core being inserted in the lugs and demountably held therein by pressure of the bristles against the comb.

4. A comb-brush comprising a brush having a core and radially extending bristles, and a comb having resilient hook-like lugs projecting laterally from its back for receiving demountably the ends of the brush core, the free ends of the lubs being spaced from the comb a distance less than the thickness or the core ends to prevent accidental detachment of the brush when snapped into position in the lugs.
