- Application February 14, 1934, Serial No. 711,270 5 claims. (c1. 15s-2oz) Y This invention relates to` an improved hairthe sections to be separated for washing and cleaning purposes.

The principal novelty is predicated upon the.A

sectional construction of the head of .the brush, this being such as to match the b1isties`oithe respective sections in such intimate and coordinating manner as to provide a bristle assembly having all the advantages ofthe regular one-y piece or solid type brush, but having the additional advantage of permitting the sections and the bristles carried thereby to be disconnected for convenient scraping and cleansing.

Brieiiy stated there is a main section which includes a head or back wherein this is slotted to form a group of companion bristle carrying members, together with a complemental `or secondary section constructed so as toV form -the complete head and including furcations or bristle carrying members cooperating with the iirst.

named members in deiining the finished or complete brush head.

One feature of the improved construction resides in the adoption and use of a practicable and conveniently locatedk resilient latch carried by the relatively movable .or secondary section which serves as a fastener for connecting the 30. two 'sections securely together n an expeditious and dependable manner. Y

A further feature of the invention is predicated upon a brush head composed of complemental sections with their portions or bristle carrying ating with retaining sockets in such a manner as to keep the two sections in an even plane and to thereby dispose the bunches of bristles in substantially ush' relationship. Y

Other features and advantages will become more readily apparent from the following description and drawings.

In the drawings: y

Figures 6 and 7 vare longitudinal and transversesectional views taken on the planes of the lines 6-6 and 7 7 respectively of Figure 1.

Figure 8 is `a cross section on the liney 8-8 of Figure 5, and

Figure 9 is a detail horizontal section on the plane of the line 9-'9 of Figure 2. Y

Briefly stated it will be observed that the two sections carrying the bristles and constituting the complete head are dovetailed together, that is the-bristle carrying rmembers thereof are interlocked and fastened through the instrumentality of dowel pins and held assembled by a manually releasable retaining latch.

VReferring now to the preferred embodiment of the invention 'illustrated in the drawings it will be seen that the main or handle equipped section of the brush shown in' Figure 4 comprises a head `forming section 10 having an integral handle 11. The portion 12, sometimes referred to as the back,v and sometimes as a head, is of rectangular or longitudinally elongated configuration. In the present instance it is 'formed' with a pair ofgspaced parallel longitudinally extending slots which denneY a group of three like bristlecarrying members 13. 'These carry rows of alined bunches kof vbristles diierentiated by the numerals 14. Thcnthere is a transverse row of bristles adjacent the junctionof the head andY Ahandle whichgare 'distinguished by the numerals 15, these being end bristles. At; their `free. end the bristle carrying members 13 are provided with -pegs or dowel pins 16. These are adapted to nt ure 5). Incidentally the. sockets are shown better ,Y

in Figure 8 andthe cooperation between the pins' and sockets is shown'inFigure 9. It isrto'be pointed out however that the pair of bristle carrying members of the section 19 are provided with similar rdowel pins 21 which extend in the sockets provided in the head 12 and this alternate arrangement of dowel pin connections keeps the two sections 10 and 19 in proper alinement, that is in a plane even with each other.y Thesegmental configuration of the connecting block 18 provides the desired finish or endV .Eormation for the vbrush making it of the general appearance of an ordinary one-piece or solid head construction. This block 18 carries a row of bristles 22 and the members 20 also carry bristles 23 all of these bristles cooperating in forming the complete bristle assembly designed to provide the desired smooth and uniform brushing action.

To prevent relative longitudinal sliding movement of the two sections of the brush head I have found it expedient and satisfactory to provide a connecting latch. This latch is shown in Figure l and denoted by the numerals 24 and is of general Y-shaped form. The diverging arm portions 25 are pinned or otherwise secured as at 26 to the free ends of the bristle carrying members 20. rlhe stem portion 27 overlies the inner end of the main brush head section 12 and has its free end fashioned into a clip. In other words it is bent down upon itself to form a camlike keeper.,

28 of the type shown in Figure 6 and this cooperates with the undercut or beveled retaining shoulder 29 in a keeper seat or recess 30 formed in the handle. The up-bent portion of the metal has its extremity bentv laterally as at 31 in a plane above the handle so as to form a convenient nnger piece or grip to facilitate disengagement of the keeper 28 from the shoulder 29. It is obvious that by simply sliding the two sections together and interlocking the bristle carrying members the keeper portion of the latch will snap automatically into the recess 30 in a practical dependable manner. It can be just as easily disengaged and the two sections then pulled apart so that the meeting portions or contacting parts thereof can be scraped and cleaned, sterilized and then allowed to dry and then again assem led for complete brush formation.

A head constructed in accordance with the principles oi the present inventive conception is simple, economical, efficient and promotes requisite sanitation desired by the individual home user, the barber, or the professional hair dresser. It possesses the requisite commercial appeal such as would merit endorsement by the trade when used in public because of its sanitation features.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size, and rearrangement of details coming within the iield of invention claimed may be resorted to in actual practice, if desired. l

Having thus described my invention, what I claim as new is:

1. A hairbrush oi the class described comprising a bristle equipped head, said head embodying a pair of complemental head forming sections including longitudinal and extending spaced parallel bristle carrying members disposed in interlocking relationship, dowel pins carried by the respective sections and receivable removably in sockets in adjacent portions, together with a latch carried by one section, said latch being formed with a keeper element, and the remaining section having a keeper seat for reception of said element.

2. A hairbrush of the class described comprising a head, said head embodying separably connected complemental bristle equipped sections, one section being provided with a keeper notch having an undercut retaining shoulder, the other section beingl provided with a substantially Y- shaped resilent latch having its stem portion terminating in a down bent cam like keeper releasably engageable with said shoulder.

3. A hairbrush of the class described comprising a head, said head embodying separably connected complemental bristle equipped sections, one section being provided with a keeper notch having an undercut retaining shoulder, the other section being provided with a substantially Y- shaped resilient latch having its stem portion terminating in a down bent cam like keeper releasably engageable with said shoulder, and further formed with an upstanding portion terminating in a laterally bent finger piece disposed in a plane above said handle.

4. A brush of the class described comprising a handle having an integral longitudinally elongated head forming section of a ilat Lfaced type, said head section being longitudinally cut to denne a group of spaced parallel members, bristles carried by and depending' from said members, said members being provided at their outer end connecting pins, a complemental brush head section fashioned for cooperation with said rst named section and including a block like end portion formed with spaced parallel bristle carrying members, said last named members being interlocked between the corresponding members of the rst named section and formed with connecting pins.
