(Cl. 15-1s4) This invention relates to brushes, particularly retractable brushes which are well adapted for brushing hair or other uses, and which may be carried very conveniently in a purse, pocket, handbag or the like.

One object of the present invention is to provide a new and improved retractable brush which has a double retracting action, and which is self cleaning.

A further objective is to provide such a new and improved retractable brush having a housing with relatively rotatable parts which extend as the bristles are retracted into the housing so as to aiord ample space to enclose the bristles.

Another object is to provide a new and improved retractable brush of the foregoing character in which the parts of the housing telescope together as the bristles are extended, so that the housing is extremely compact with the bristles in their extended position.

It is a further object to provide a new and improved `retractable brush in which loose hair and other foreign matter are automatically stripped oi the b ristles as they are retracted.

Still another object is to provide a retractable brush which is not only effective and highly convenient but is .low in cost and easy to manufacture.

Further objects and advantages of the present invention will appear from the following description, taken with the accompanying drawings, in which:

Fig. l is an enlarged elevational View, partly in section, of a retractable brush to be described as an illustrative embodiment of the present invention, the brush being shown in its extended position. v

Fig. 2 is a view similar to Fig. 1 but with the brush in its retracted position. n

Fig. 3 is a top plan view of the brush, partly in section.

Fig. 4 4is` an exploded elevational view of the brush, with the components partly in section.

Fig. 5 is a bottom plan view of the cover or upper element of the brush.

Fig. 6 is atop plan view of the lower housing element of the brush.

Fig. 7 is a bottom perspective view showing the bristle carrying plate embodiedin the brush.

Fig, 8 is a top perspective view showing an actuating plate normally secured to the underside of the bristle carrying plate when the brush is assembled.

Figs. 9-10 are developed elevational views showing spiral cam elements which are provided within the upper and lower housing members.

As already indicated, the drawings illustrate a brush 12 having bristles 14 which are retractable into a housing 16, so that the brush may be carried very conveniently in a purse, handbag, pocket orthe like. In this case, the housing 16 is, generally drum shaped and is formed with outer and inner telescopically related parts or members 18 and 20. fThe brush is retracted and extended by rotating the members 18 and 20 with respect to each other. Within the housing members 18 and 20 is a bristle carry- -ing member -22 which is moved back and forth to' extend ICS and retract the bristles 14 as the housing members 18 and 20 are rotated. A

As the bristles 14 are extended, the housing members 18 and 20move together, as shown in Fig. 1, so that the housing will be extremely compact when the bristles are extended. As the bristles are retracted into the housing 16, the housing member 18 and 20 move apart into an extended position, as shown in Fig. 2, so as to aiord ample room for the bristles. The extending and retracting movement of the bristles 14 is twice as great as the extending and retracting movement of the housing members 18 and 20, so that the brush is double acting. As the bristles 14 are retracted, they are automatically stripped of hair and other foreign material.

It will be seen that the illustrated upper and lower housing members 18 and 20 are generally cup shaped, having general cylindrical side walls 24 and 26. In this case, the side wall 26 ofthe lower member 20 is received within the side wall 24.

The upper housing member 18 has a top or end wall 28 with a large number of hoes 30 therein to receive the bristles 14. It will be seen that each of the holes 30 has a flared lower portion 32 to facilitate initial assembly of the brush. By virtue of the reception of the bristles 14 in the holes 30, the bristle carrying member 22 rotates with the upper housing member 18.

In this case, the bristle carrying member 22 takes the form of upper and lower plates 34 and 36, which are cemented or otherwise suitably secured together. As illustrated, the upper plate 24 is formed with a plurality of button headed downwardly projecting studs or lugs 38 which are received in apertures 40 formed in the lower plate 36. The engagement of the lugs 38 with the apertures 40 insures that the plates 34 and 36 will rotate together.` Moreover, the provision of the studs 38 and apertures 40 assists in securing the plates 34 and 36 together. Various materials may be employed for the plates 34 and 36. For example, the plate 34 may be made of plastic, while the plate 36 may be made of metal.

The bristles 14 may be mounted in sockets 42 formed inthe lupper plate 34. It will be understood that the bristles may be arranged in tufts as shown, or may be secured to the plate 34 `as individual bristles. In some cases the bristles 14 may be molded integrally with the plate 34, rather than being formed separately and secured thereto as shown.

Thread or cam means may be provided to advance and retract the housing elements 18 and 20 as they are rotated with respect to each other. As shown, the thread means take the form of spiral cams or threads 44. In this case, the spiral threads 44 are formed within the cylindrical side wall 24 of the upper housing member 18. The illustrated threads 44 take the form of grooves in the side wall 24. Lugs or ears 46 are formed at the upper end of the inner side wall 26 to engage the grooves 44. Thus, the upper and lower housing members 18 and 20 will extend and retract as the members are rotated with respect to each other. The extending movement is limited by the engagement by the ears 46 with the lower ends of the spiral grooves 44. To limit the contracting movement, the lower housing member 20 has an outwardly projecting flange 48 on its lower end, to engage the lower end of the upper side wall 24. The ange 48 also provides a convenient hand grip on the lower housing members 20.

As shown to best advantage in Fig. 9, three of the spiral grooves 44 are provided in this instance. The grooves 44 are quite steeply pitched so that very little rotary movement is required to extend and retract the housing members 18 and 20.

In order to provide a double extending and retracting movement for the bristles 14, thread means are provided ,Patented Dec. 15, 1959 to act between the lower housing member 20 and the bristle carrying member 22. In this case, the thread means take the form of spiral threads or cam grooves 50 formed on the inside of the lower side wall 26 as shown to best advantage in Fig. l0. Three steeply pitched grooves 50 are provided in this case. The grooves 50 are engaged by ears or lugs 52 on the bristle carrying member 22. More specifically the ears 52 are formed on the lower plate 36 of the bristle carrying member 22. The ears 52 may be slightly twisted so as to slide smoothly in the grooves 5).

To afford access to the inside of the housing 16 the lower housing member 20 is formed with a lower end wall 54 with an access opening 56 therein. A closure panel 58 is normally mounted in the opening 56 and may be held in pace by slightly protruding lugs or ears 60 adapted to snap into grooves 62, formed in the lower wall 54. An inclined notch 64 may be formed in the lower wall 54 at one point along the edge of the opening 56, so that a coin or the like may be inserted to pry out the closure panel 58.

In this case, the access opening 56 occupies most of the lower wall 54, so that the inside of the housing 16 may readily be cleaned when the closure panel 58 is removed. The panel 58 may easily be snapped back into place when the cleaning operation is completed. It should be noted that the spiral cam grooves 44 and 5) are oppositely angled so as to providey a double advancing and retracting action. The bristles 14 are advanced and retracted by rotating the cup shaped housing members 18 and Ztl with respect to each other. As the bristles are advanced, the spiral cam grooves 44 cause the housing member Ztl to move into the housing member 18. This makes the housing 16 more compact and also tends to extend the bristles 14. Because of the reception of the bristles 14. in the holes 30, the bristes and the bristle carrying member 22 rotate with the upper housing member 18, and thus rotate relative to the lower housing member 2d. The action of the cam grooves 50 causes the bristle carrying plate 22 to advance within the lower housing member' 20. Thus, the advancing movement of the bristles 14 is twice the telescopic movement of the housing members 18 and 20.

When the bristles 14 are retracted, the housing members 13 and Ztl are telescopically extended, as shown in Fig. 2, while the bristle carrying member 22 is moved downwardly within the lower member 20. Thus, ample room is provided within the housing 16 so that the bristles 1.4 may be fully retracted. -Iowever, the upper ends of the bristles 14 remain within the holes 30 so that the bristles may readily be extended again.

As the bristles 14 are retracted through the holes 30, the upper end wall 28 automatically strips loose hair, dandruti flakes and other foreign materials off the bristles. Thus, the brush is se'f-cleaning. Because of the double retracting and advancing action, very little rotary movement of the housing members 18 and 20 is needed to advance and retract the bristles. The housing 16 is eX- tremely compact when the bristles are extended so that the brush is easy to hold and use. Nevertheless, the housing provides ample room for the bristles when they are retracted.

.t will be recognized that the housing members as well as the bristle carrying plate 34 may readily be molded from plastic. The lugs 46 and 52 may readily be i11- serted into the grooves 44 and S0 by slightly exing the side walls 24 and 26. Thus, the components of the brush are readily made and easily assembled. Accordingly, the brush may be easily manufactured at low cost.

Various modifications, alternative constructions, and equivalents may be employed without departing from the true spirit and scope of the invention, as exemplified in the foregoing description and defined in the following claims.
