Application June 9, 1945, Serial No. 598,561

6Claims. (01.15-203) The invention relates to brushes in which the bristles may be projected and retracted, and is partlcularly adapted for a hair brush to be carried in a pocket, purse or bag although the invention is not limited to such brushes.

One object of the invention is to closely surround each tuft of bristles with a portion of the brush body so that the bristles may be firmly supported transversely of their length during a brushing operation.

Another object is to provide for the divergence of the bristle tufts when they are projected from the body, thus increasing the effective overall surface of the ends of the projected tufts over the surface of the body from which they are projected.

Another object is to provide for such divergence or spreading of the bristle tufts in one plane while effecting the projection and retraction by movement of the inner or anchored ends of the tufts in another plane.

Another object is to effectively anchor and guide the bristle tufts to the brush body and associated parts.

In the accompanying drawings illustrating the inv-ention Figure 1 is a side elevation, sectioned in part, of a brush showing the tufts of bristles projected.

Figure 2 is a top view of the brush with a part broken away to more clearly illustrate the construction.

Figure 3 is an end view of the brush looking towards the left hand end in the Figures 1 and 2.

Figure 4 is a longitudinal vertical section through the brush showing the bristles retracted.

Figure 5 is an isometric view of the tuft mounting member movable along the inner face of the back, of the brush.

Figures6 and Tare elevations of a single bristle tuft and its socket, the two views being at right angles to each other.

Figure 8 is an end view corresponding to Figure .3 but showing another form of the invention.

Figure 9 is a top view of a segment of the structure shown in Figure 8.

Figures 10, 11 and 12- are elevational views of a bristle tuft and its socket as shown in Figures 8 and 9 and are taken upon the corresponding view-indicating lines of Figure 9.

Figure 13 is a fragmentary isometric view illus- Figure 16 is a vertical transverse section 2 f through the connections between the bristle sockets and the member to which they are attached in another modification.

Figure 1'7 is a top view of the member to which shown 5. The axes of the apertures are inclined to the surface of wall 3 and preferably each aperture is elongated longitudinally of the body so that the tuft as a whole may be inclined longitudinally of wall 3, without bending, as shown in Figure 4, or may be perpendicular to, or radial of, wall 3, without bending, as shown in Figures 1 and 3.

The bristles of each tuft 5 are seated in a socket 6 which is pivoted to an individual lug 1 struck up from a mountin plate member 8 which is slidable longitudinally of the body back wall 9. The sides of plate 8 may be received in grooves provided therefor in the body side walls III. A pin H, secured to plate 8, may project through a slot in back wall 9. The slot extends lengthwise of a wall and this arrangement provides for manual sliding of plate 8 longitudinally of the I brush body.

Preferably each aperture 4 is adapted to receive a single bristle tuft and so surrounds the tuft that it affords support for the bristles longitudinally and transversely of the brush whether the bristles are retracted, as shown in Figure '4,

"(Figure 3), the distance between adjacent apertures transversely of the brush being greater than the distance between corresponding lugs 1. Hence, when plate 8 is moved to the left from the position shown in Figure 4 and tufts 5 are pro-: jected from wall3, tufts adjacent to each other transversely of the brush will diverge outwardly, as best shown in Figure 3. This provides the outer ends of the brush (bristles) with a larger overall area than the brush body and, since the outer ends of tufts So at the sides of the brush are positioned outwardly from the brush body side walls 10, the brush may be rolled during the stroke accommodating the variation in the angle between the user's arm and the strand of hair, thus making the action of the brush more con,- venient than if the tufts are straight and parallel.

In the arrangement shown in Figures 1-7, all of the tuft sockets or bases 6 are the same and each has a flat ear l3 disposed in the same longitudinal plane as the axis of the brush. The mounting plate lugs l are inclined at various angles to the plate to provide the desired mounting of the diverging tufts and ears l3 and lugs l are pivotally connected and bear flatly on each other and the tuft swings in the inclined plane of the lug as the tufts are projected and retracted.

Figures 8-12 illustrate another form of the invention in which the brush body is. substantially the same as that previously described and the tuft mounting plate 2| is similarly mounted in the body but its lugs 22 are all perpendicular to the plate and the desired position of. the tufts 23 is efiected by inclining the ears 24 on the sockets 25 according to the angles which it is desired the tufts are to assume. Those tufts which are disposed perpendicularly along the median line i plate, 31, and the tuft structure 32 and the connection of the same to the base by sockets 33, having ears pivoted to lugs 34 on plate 3 l are substantially the same as shown in Figures 1-7, but

intermediate plate 3|, and front wall 35 there is Provided a series of guide plate devices 38 each extending from side to side of the brush and provided with pintles 31 by which the plate is pivoted in the brush side walls 38. Each plate 36 has a plurality of cylindrical passageways, 39 through which the tuft extends.

When the tufts are projected, and retracted, plates 36 swing on their pintles 3.1 to accommodate the angular movement of the tufts. Irrespective of the position of the tufts, they are closely surrounded by passageways 3e and are more firmly positioned.

These figures illustrate a variation in the tuft socket structure in that each socket is, provided with a pair of cars 33a which receives the corresponding mounting plate lug 34 between them, thus placing the pivot. pin. double shear and providing a more stable connection between the tuft and the mounting plate.

Figures 16-18 illustrate another arrangement of the connection between the socket d9 of each Wit 4.1 and a, mounting plate 42 which corresponds, generally to the mounting plates previously described. The mounting plate has a series of spherical cups 63 each slotted as indicated at H, the slots being disposed at different angles to the plate. Each tuft socket has a ball-like car 46 adapted to be received in a cup 43. The inclination of the tuft is determined by the angular disposition of the slot M which receives the neck 1 by which ball 46 is connected to socket 40* It will be understood that any of the tuft socket and backing plate connections may be used in either form of the projecting and retracting structures andrif desired, more than one type of 4 connection may be used in the same brush for different tuft sockets.

All forms of the invention have the common feature of adapting a, series of tufts for radial projection from the brush body as the mounting plate is slid transversely of the length of the tufts, and the feature of providing an individual aperture for the tuft which tends to hold the tuft more firmly in its position and to remove lint or othermaterialadhering to the tuft as it is retracted.

The details of the structure may be varied other than as described and illustrated without departing from the spirit of the invention, and the exclusive use of those modifications coming within the scope of the claims is contemplated.

What is claimed is:
