3 Claims.

This invention relates to a case brush and particularly to a case brush to be carried in the pocket or a hand bag.

The objects of this invention include: the conservation of space, the protection of the brush against injury and the entrance of foreign matter; a simple and inexpensive pocket brush. Other objects will appear from the detailed description which follows:

In accordance with this invention the brush is enclosed within a case constituting a shell like housing, the brush and housing being relatively slidable. In the closed position of the device the brush is protected by the housing, while in the open position, the brush is positioned in the opening in the case, the latter constituting a handle or hand grip; suitable means is provided operable by the pressure of the operators iingers to lock the brush and handle in fixed relation in the open position of the device.

In the drawing comprising one sheet of eight iigures numbered l to llinclusive:l

Fig. l is a perspective view of one form of case brush in open position.

Fig. 2 is a vertical section of the same in closed position taken along the line 2 2 of Fig. 3 looking in the direction of the arrows and with certain of the parts partially broken away to disclose the constructon of the brush foundation.

Fig. 3 is an end view with the brush closed position.

Fig. 4' is a vertical section of the device with the brush in open position.

Fig. 5 is a side view of a modified form of the device in closed position with certain of the parts partially broken away.

Fig. 6 is a vertical section of said device taken along the line 6 6 of Fig. 5 looking in the direction of the arrows.

Fig. 7 is a vertical secton of the device of Fig. 5 with the brush in open position taken along the line '7 7 of Fig. 5 looking in the direction of the arrows; and

Fig. 8 is a horizontal cross section of the device taken along the line 8 8 of Fig. 5 looking in the direction of the arrows.

Like reference characters designate corresponding parts throughout the several figures of the drawing.

In its simplest form the case brush 1 (Fig. 1) embodying the invention consists of a case 2 made of a suitable thin material comparatively light in weight and preferably resilient. Case 2 may be made out of a single sheet of material bent to form a U shaped holder having oppositely 1932, Serial No. 636,098

disposed side walls 3, braced at the open ends by the stops 4 4. If the material is resilient the case 2 may be compressed by the application of slight pressure exerted by the thumb and ingers as best illustrated in Fig. 4. The brush consists of a suitable brush head 5 for the bristles 6 6. The bristle foundation 8 is secured in the brush head 5 in any preferred manner. One smple and inexpensive way of doing this is to embed the bristle foundation S in a brush head composed of cellulcid or the like which is plastic and capable of being molded when heated. The bristles may be clamped between two clamping members 9 and li) (best illustrated in 8) which members are grooved at il and 12 to receive the bristle foundation 8; or the bristle foundation may be secured in the brush head by means of staples 13 passing around each bristle :foundation 8. This construction is likewise shown in Fig. S.

The case 2 is of substantially the same dimensions as the brush so that in the closed position the brush is completely housed within the case 2. The brush is freely slidably mounted within the case 2, the brush head 5 sliding in the U shaped channel or guide-way formed between the side walls 3 3 and curved top wall of case 2. To facilitate the back and forth sliding movement of the brush in the case 2 suitable linger grips 7 7 projected from brush head 5 are provided. These linger grips project slightly beyond the wall of case 2 and it is convenient to position the finger grips 7 7 at opposite ends of brush head 5 (see Figs. l, 2 and 3) and to leave the ends of case 2 open to denne U shaped openings constituting guide-ways for the finger grips 7 7. The stops 4 4 serve to limit the extent of the opening movement of the brush the underside of the brush head 5 resting against the inner surfaces of the stops 4 4 when the brush is in open position is best understood by comparing Figs. 2 and 4.

In this simple and presently preferred form of construction the brush head 5 is held against sidewise movement by the side walls 3 3 pressing against the side walls of the brush head 5; and against endwise movement by the co-action between the linger grips 7 7 and the end walls of the case 2.

To operate the brush it is only necessary to hold the case lightly between the thumb and ngers of the one hand substantially as indicated in Figs. l and li and to press the linger grips '7 7 between the thumb and forefinger oi the other hand. Brush and case may then be opened or closed by initiating relative sliding movement of the brush and case. In the open position the brush head may be locked to prevent the brush from sliding back into the case when the brush is in use by slightly compressing the side Walls 3-3 toward each other between the thumb and fingers as best illustrated in Fig. 4. This slight pressure of the side walls reduces the internal separation between the side walls 3 3 causing them to grip the brush head 5-5 which is now firmly wedged and cannot be moved relative to case 2 until by the release of the finger pressure the resilient walls 3--3 are restored to their normal position and sufficient internal separation between the side walls 3-3 exists to permit brush head 5 to slide freely in the guide-way formed between the said side walls.

The inventive idea is capable of various modifications some of which are illustrated in Figs. 5 to 8 inclusive. As previously described the brush head may be stapled instead of molded and the locking action caused by the use of a case 2 made of self-resilient material may be replaced by any suitable locking button, lever, spring or the like. One such form appears in the modification wherein the brush head 5 is provided with a suitable miniature chamber 18 for receiving a spring button unit consisting of a button 14 having an enlarged base flange 15 forming a bearing surface for a coiled spring 16 positioned within the chamber 18. The button 14 engages a suitable bevelled or cone shaped opening 17 in the side wall 3 of case 2 to lock the brush case together in the open position of the brush. To close the device the button 14 is pressed inwards by finger pressure and the brush head is moved into the housing button 14 then assuming the position best illustrated in Fig. 8 coiled spring 16 being under tension. When it is desired to use the brush it is drawn outwards in the general manner previously described until the button 14 once more engages in the opening 17.

The case 2 performs a triple function. It is a housing for the brush in the closed position; a hand grip or handle for the brush in the open position; and a guide-way in which the brush is freely slidable in opening and closing the device.

Case 2 may be made of any preferred selfresilient material Whether metallic or non-metallic. A very satisfactory and inexpensive case brush may be manufactured employing celluloid both for the case 2 and for the brush head 5.

What is claimed is:

l. In a case brush and in combination, an elongated brush-head; and a case in which the brush-head is freely and :slidably mounted, the case constituting a housing for the brush-head in closed position, a guide-way for the brush-head during the sliding movement, and a hand grip for the brush-head in open position; the walls of the case being resilient and inwardly yieldable under inter-finger pressure to lock brush-head and case against relative movement in the open position of the brush-head.

2. In a case brush and in combination, an elongated brush-head; a case in which the brushhead is freely and slidably mounted, the case constituting a housing for the brush-head in closed position, a guide-way for the brush-head during the sliding movement, and a hand grip for the brush-head in open position; and means for limiting the extent of -the opening movement, the walls of the case being resilient and inwardly yieldable under inter-linger pressure to lock the brush-head and case against relative movement in the open position of the brush-head.

3. In a case brush and in combination, an elongated brush-head; a case in which the brush-head is freely and `slidably mounted, the case constituting a housing for the brush-head in closed position, a guide-way for the brush-head during the sliding movement, and a hand grip for the brush-head in open position; and means for cross bracing the open end of the case to limit the extent of the opening movement, the walls of the case being resilient and inwardly yieldable under inter-finger pressure to lock brush-head and case against relative movement in the open position of the brush-head.
