This invention relates to brushes, and ank object of the invention is to provide a compact brush structure particularly well adapt ed to be carried about in the pocket of the user or in a traveling bag or other receptacle used by travelers. The said brush comprising a back or brush head carrier which is concavoconvex and has detachably connected thereto the bristle carrying head which is constructed of flexible material so that it may be flexed to fit within'the back, a cover being provided for connection with the back or brush head carrier to entirely inclose the bristles of the brush, thus preL venting the collection of dust, dirt or other matter by the bristles when not in use and avoiding danger of garments becoming soiled by bristles which may have become oily fromuse.
A further object of the invention is to provide means which will permit the ready connection or ydisconnection of lthe brush head carrier and the cover in ,such manner through which the users finger is inserted to extend the bristles carrying body of the brush outwardly in opposed convexed relation to the carrying back 4to render the brush operative. .j
y A further object of this invention is to provide a bristle carrying body or head for the brush which is constructed of a sheet of resilient rubber provided with a plurality of openings therein through which the bris- 'tles kare inserted and which sheet of resilient rubberhas a layer or sheet of rubber placed over the inner surface thereof and vulcanized thereto for securely retaining the bris- Specification of Letters Patent.

tles in place and preventing them from Working loose during the use of the brush.
Other objects of the invention will ap* pear in the following detailed description taken in connection with the accompanying drawing, forminga part of this specification, and in which drawing:
Figure 1 is a perspective view of the improved brush. y f.
Fig. 2 is a longitudinal section of the brush in a collapsed position.
Fig. 3 is a cross section throughthe brush collapsed.
Fig. 4y is a longitudinal section through vthe brush extended.
Fig. 5 is a cross section through the brush extended.
Fig. 6 is an inner plan of the cover illustrating the mirror `carried thereby, and
Fig. 7 is a detail perspective view illustrating the manner of attaching the bristles to the bristle carrying body of the brush.
n Referring more particularly to the drawings, the improved brush structure includes the separable housing parts 10 and 11, the
former of which constitutes the back or main body portion and is substantiallyconcavo-convexly curved, presentingy its convexed surface outwardly. It has an annular inturned edge 12 which serves to retain a bristle carrying body 13 yof the brush in operative relation thereto. This bristle carrying body 13 comprises a layer 14 of ilexible rubber which is provided with a plurality of openings 15 through which the bristles 16 of the brush extend. The bristlesy 16 may be bent to lie across a portion of the inner surface of the layer 14 of pli-' ablerubber as illustrated in Fig. 7 and extend downwardly through adjacent open-I *ings if desired and if long enough, or if they are not ,long enough to be extended through two openings, their inner ends may be bent merely to overlie or engage the inner surface of the strip 14. A strip or layer 17 of substantially raw rubber is placed over the inner surface of the vlayer 14 and is vulcanized for securely anchoring the` bristles 16 to the body 14. In vulcanizing the strip of rubber 17 tothe sheet or layer 14 some of the rubber of the sheet 17 will enter the openings 15 in the sheet 14 securely sealing the openings and locking or fastening the bristles securely in place.
As clearly shown inthe kdrawings thebristle carrying body 13 is oval in shape and when in operative position bulges outwardly from the brush back 10, presenting a convexed surface opposite to the convexed surface of the body 10. However, this bristle carrying body of the brush is adapted to be flexed to lie within the brush back 1() as shown in Figs. 2 and 3 of the drawings at which time the curvature of the body 13 conforms to the curvature of the brush back or part 10 of the brush structure. A relatively thin sheet 19 of Celluloid or analogous material may be placed between the confronting faces of the brush body 13 and the part 10 of the brush structure and when the former is iiexed inwardly, this plate 19 lies in facial abutment with the inner concaved surface of the part 10. This part or brush carrying back 10 is provided with a nger opening 2O centrally therein, through which a finger is inserted to extend the iiexible back 13 of the brush or to force it out of the carrying back 10 into an operative position.
The part or section 11 of the brush structure forms a cover for the bristles 16 when the brush is collapsed as clearly shown in Figs. 2 and 3 of the drawings and is preferably oval in shape or shaped to conform to the shape of the brush carrying back 10. Its major portion is preferably fiat and has an annular upstanding edge portion or flange 20 formed thereon, and when the brush is flexed inwardly and the two parts thereof are connected, at which time the brush is in condition to be carried about in the pocket or hand luggage of the user, the edge portion of this iiange 20 engages the brush carrying back 10 at its girth, or at the junction of the inturned flange 12 with the concavo-conve-x back of the brush carrying part or section 10. The flange 20 has lips 22 and 23 formed thereon at opposite points substantially at the minor axis of the cover, which engage over the outer convex surfaces of the section 10 to connect the sections 1() and 11 for preventing accidental relative movement thereof. The lip 23 is provided with a cut out portion 24 forming a finger or thumb receiving recess or opening which will enable the user to get a firm grip on the section 10 beneath the flange 12 for disconnecting the sections 10 and 11. In connecting the parts 10 and 11 of the brush after the brush carrying body 13 has been iiexed into the part 10, the part 10 is tilted at an acute angle with respect to the part 11 and one edge thereof is inserted against the lip 22 after which the brush back is forced against this lip and downwardly until the lip 23 engages over a portion of the convexed surface of the part 10 which lip 23 cooperates with the lip 22 to securely hold the parts connected.
A glass V25, preferably a mirror may be placed within `the part 11 with its silvered side inwardly, so that when the parts 10 and 11 are disconnected, this cover part 11 may be held in one hand of the user permitting use of the mirror while brushing his hair with the brush part. The mirror 25 is preferably beveled or reduced in thickness at its edge portion and is coniinedin the cover part 11 by a ring 26 of any suitable material which engages the inner sur face of the flange 20. The flange being curved slightly extending inwardly toward the center of the cover part at its outer edge, as clearly shown in F ig. 2 of the drawings, the ring 2G will be confined in place for securely holding the mirror 25 in place.
yThis ring 26 is preferably constructed of any suitable material of slight elasticity so that when the mirror 25 is placed within the cover part, the ring may be sprung into place.
While in the drawings, a military brush is illustrated it is to be understoodthat the principle of the present brush structure may be applied to clothes brushes, hand brushes or any analogous type of brush without departing from the spirit of this invention.
Changes in details may be made without departing from the spirit of this invention. but; f
