Sept. 16, 1947. A, s, JOHNSON BRUSH yCONSTRUCTION Filed Feb. 8, 1946 Arrone/YE Y6 Patented Sept. 16, 1947 UNlTED STATES TENT OFFICE 3 Claims.

This invention relates to brushes and more particularly to brushes intended to be carried in the pocket or hand luggage.

Most brushes heretofore known to the art which have been intended to be carried on the person or in the personal luggage of an individual, such as, for example, hair brushes or clothes brushes, have not been provided with a suitable carrying case so that the bristles thereof collected dirt and other foreign matter. In most instances where carrying cases have heretofore been provided for such brushes, the cases or protective coverings have been of the type which when the brush is in use it is completely disassociated from the brush. Such construction has many undesirable features, a principal one being that when the case has been removed to use the brush, it is easy to inadvertently misplace the case so that when it is again desired to place the brush in the case the individual is put to considerable inconvenience in locating the same.

In a few instances, brushes have heretofore been known to the art wherein the brush element and a. protective casing or covering therefor have been permanently interconnected. However, in those few instances such brushes have heretofore involved a complicated construction which is not desirable from a commercially economical production standpoint and are relatively diincult to maintain in repair. It is an object of my invention to permanently associate a brush member with a protective casing therefor in such a manner that the complete assembly may be economically manufactured and has a minimum number of parts.

It is a further object of my invention to associate a brush with a protective casing in such a manner that the brush may easily be removed from or placed in the protective casing.

Yet, a further object of my invention is to associate a brush member with a casing therefor in such a manner that when the brush is retracted into the casing the bristles thereof are adequately protected by the casing and when the brush is removed from the casing into operative position to be used in brushing, the casing forms a convenient handle which may be grasped in the hand during the brushing operation.

It is a further object of my invention to associate the brush in such a manner with the casing that the brush is at all times connected to the casing and when the brush is retracted into the casing a portion of the casing underlies the bristles of the brush.

Other and further objects of the present invention will be apparent from the following description and claims and are illustrated in the accompanying drawing which, by way of illustration shows a preferred embodiment and the principle thereof and what I now consider to be the best mode in which I have contemplated applying that principle, Other embodiments of the invention embodying the same or equivalent principle may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claims.

In the drawings:

Fig. l is a top plan view of a brush embodying the principles of my invention showing the brush retracted into the case in carrying position;

Fig. 2 is a side elevational view of the brush as shown in Fig. 1;

Fig. 3 is a bottom plan view of the brush as shown in Figs. 1 and 2;

Fig. 4 is a side elevational view showing the brush in operative position extended from the casing;

Fig. 5 is a sectional view substantially taken on the line 5-5 in Fig. 4.

The brush I0 shown in the drawings comprises in general a brush member 0r brush head I I and a casing I2 therefor. The casing I2 and the back I 3 of the brush II may be made of any suitable material such as Wood, steel, hard rubber or a plastic, However, I prefer to construct the casing i2 and the back I3 from a. suitable transparent plastic available on the market such as, for eX- ample, the plastic sold under the trade namel Lucite.

The casing I2 comprise-s side walls I!! and I5, a top wall I6, a rear wall Il, and a bottom wall I8 which extends forwardly along a portion o1" the length of the casing I2 from the rear Wall I'I and thereby stiiiens and gives support to the sidewalls il! and I5 at the lower edges thereof. As best seen in Figs. l and 3 the front end portion of the casing I2 and the forward bottom portion of the casing I2 are open se that, as will be more specifically set forth hereinafter, the brush II may be easily inserted into the casing I2 and retracted therefrom. Slots I9 and 20 are provided in each of the side walls I4 and 5 for purposes which will be presently described. As best seen in Figs. 2 and 4 each of the slots I9 comprises substantially parallel upper and lower end portions 2| and 22, respectively, the inner end portions of which are interconnected by a slant-` ing transverse portion 23. Similarly, each of the slots 20 comprises substantially parallel upper and lower end portions 24 and 25, respectively, the inner end portions of which are interconnected by a slanting transverse portion 26.

The brush member II comprises a back I3 into which are set bristles 21 in a manner well known to the art. The front end portion of the back I3 has corrugations formed thereon, or may be otherwise roughened, to provide a linger grip 28 for the easy insertion of the brush into and the removal of the brush from the casing I2. Follower means in the form of guide rods 29 and 30 extend through the back I3 transversely to the longitudinal axis thereof, and when the brush member II is mounted in the casing I2 the rod 29 extends through the slots I9 in the side walls I4 and I5 of the casing I2 while the rod 39 extends through the slots 20 in the side walls I-'l and I5 in the casing I2. Thus, the brush I I is supported from the casing I2 by the rods 29 and 30 which extend through the back I3 and the slots I9 and 29 respectively. 'Ihe rods 29 and 39 are retained in position through the back I3 and the slots I9 and 29 respectively by means of retaining washers 3| and 32 respectively. The washers 3| and 32 are placed on the ends of the respective rods and the ends of the rods are then attened or upset to prevent the washers from slipping off.

In operation it will be noted that when it is desired to carry my brush in a pocket or pack it in luggage the brush II is enclosed within the casing I2 in the position shown in Figs. 1, 2 and 3 with the rods 29 and 39 resting in the upper portions 2| and 24 of the slots I9 and 2|] respectively. It will be noted that when in this position the bottom wall I8 which extends forwardly from the rear wall |1 underlies the most rearwardly positioned bristles 21. When it is desired to use the brush member I| in a brushing operation the brush member II may be easily removed from the casing I2 by grasping the finger grip 28 in one hand and the rear portion of the casing l2 in the other hand and, by pulling on the brush I2, thereby move the rods 29 and 30 forwardly and downwardly from the upper portions 2| and 24 to the lower portions 22 and 25 of the slots I9 and 20, respectively, in which latter position the bristles 21 extend from the casing I2 in usable position, as shown in Fig. 4. It will be noted that when the brush member II is extended from the casing I2 as best shown in Fig. 4 the rear portion of the casing I2 provides a convenient handle which may be grasped in the hand during the brushing operation.

To replace the brush |I within the casing I2 the operator may push on the forward end portion of the brush II and the rearward end portion of the case I2 and thereby slide the rods 29 and 30 up the inclined portions 23 and 26 of the slots I9 and 20 until they come to rest in the rear of the ilat portions 2| and 24, respectively, of the slots I9 and 2D, at which point the bristles 21 will again be positioned within the case I2 and protected thereby.

From the foregoing description of the construction and operation of my brush taken in conjunction with the accompanying drawings it will be apparent that I have provided a novel and practical brush wherein the bristles are well protected when the brush is in closed or carrying position within the case, and embodying a novel combination of parts which is sturdy in construction, positive in action, simple to operate, and will give long and continuous service.

Hence, while I have illustrated and described the preferred embodiments of my invention, it is to be understood that this is capable of variation and modification and I therefore do not wish to be limited to the precise details set forth, but desire to avail myself of such changes and alterations as fall within the purview of the following claims.

I claim:
