his. invention relateslto brushes. such. as are used in barber; shops and; beauty parlors and, am g other: objects, aims-to provide an improved handle'having provision to. secure a bundle of fihcrslor bristles. in; thehandle'socket and improved meanswhereby thefiberspmay be quickly removecland replaced; so: that amnew or clean briishmaybe. used; on: eachcustomer.

Other aims and advantages of the invention willeappear.- in. the following description, when considered in connectionwith 'the accompanying drawing, wherein:

.Rig. 4;.is. a fragmentary'sectional view showing 22 s ns-buy. modified form .of. brush.

v. -brush handle having provision to eject the bristles and to permit a new bunch of hair, fiber or bristles to be inserted so that a sanitary brush in the same handle can be used on different customers.

Referring particularly to the drawing, the

'brush handle isshown as being made in two sections or parts which may be of any suitable material and comprises a brush holding or lower part 10 and a screw carrying on upper part 11 rotat- -ably mounted on the brush holding part or section. Referring to Fig. the brush holding part is shown as having a flared bristle socket or opening 12 in the lower end to receive a bundle of fibers or bristles 13 suitably tied together or bent upon themselves to form a loop 14 at the upper end, as shown in Fig. 2.

The screw carrying part 1101? the handle preferably has a cylindrical projection 15 inserted in an axial, cylindrical opening 16 in the upper end j of the part 10 and is secured for relative rotation with respect to said part by means of pins or screws 17 having projections which extend into an annular groove or channel 18.

The upper section 11 is hollow and preferably has multiple screw-threads 19 in the form of helicoidal surfaces generated by angles of equal sides whose vertices'leanupon helicallines ofconstant pitch. Av screw member-20 m the form of a cylindrical block having 1 screw-threads mating with the threads 19 is mounted inthe upper part and: carries a' non-circulanon prismatic plunger rod or ban 21 which extends through a non-circular axialopening 22in the-lower-part and this plungerv carries a: suitable hook 23 whichmayhave: eithera rounded orpointed end to engage thebristles craloop on a bundle offibers as the casezmaybe. ln l ig. 2a wireonrubberloopor ring 24-; isarranged: on the bentportion ofthe fibers and: isconnected: to thehook 23. Thear rangement issuchthat the upper part llfl of the handlemay be turnedltoeject the=bristles orfibers by means of the plunger andto pulla new-bundle of fibers into the socket.

In Fig. 2, there is shown'brush-expelling-means in the-form. of -a1 coil spring 25 within a-cylindrical recess: 26- around: the lowerhookedj end of the plunger-and adapted} to be compressed'by' thebundleofifibers or-br-istles so that, when the plunger is moved downwardlyto ejectv the fiber-s, the. spring. will assist in expelling them from the socket. It; is: contemplated, however, that theplun'ger may be retracted or'pulled inwardly sufliciently far to break the loop 24 so that the spring will eject the loose bristles. This may be done when the bristles are to be destroyed.

The upper and lower sections of the handle are preferably knurled or roughened, as indicated in Fig. 1, to provide convenient gripping surfaces and enable the user to turn the sections relative to each other. The multiple screw-threads, when such threads are used, enable the bristles to be ejected and replaced by turning the sections only a few turns. The bristles are preferably treated to soften the end portions which rub the face and are impregnated with soap or cosmetics so that they are ready for instant use.

For barber shop use, especially when cheap bristles are employed, it is desirable to provide means to destroy the bristles or render them useless after they have been used on one customer. This may be accomplished in various ways. For example, the bill of the hook may be so shaped that, when it is removed from they loop of the brush it will scuff or displace the fibers. However, in Fig. 4 there is shown means to render the bristles useless. In this example, a knife blade 27 is secured in the handle section 10 and projects into the socket 12 below the spring 25. The bundle of bristles 13 is tied below the loop portion 14, in which the plunger hook 23 engages, by a string or band 28. This band is cut by the knife as the bundle of bristles is pulled into the socket. Thus, the fibers are loose and some of them are displaced or tangled when ejected. When using this type of brush, a barber has to insert a new bundle of bristles every time a used bundle is ejected.

It will be seen that the improved brush handle may be used almost indefinitely and plain, soaped or powdered bristles of different types or degrees of fineness to suit the needs of the user may be carried in stock ready to be secured in the handle socket. One set of handles with differently shaped sockets may be provided for different sizes of brushes or kinds of bristles. A new or sterilized set of bristles of the same size may be put in the handle for each customer. It

will be understood that many variations of the bundles of fibers or bristles may be used and that the mode of connecting them to the handle, as well as the shape of the socket, may be widely varied.

Obviously, the present invention is not. restricted to the particular embodiment thereof herein shown and described.

1. .A brush of the character described, .in combination, a handle portion presenting a bristle socket in the lower end; a rotatable portion constituting a part of the handle and removably connected to the bristle carrying portion; screwthreads within said rotatable portion; a screwthreaded plunger member mounted in said screwthreaded portion of the rotatable member and projecting into the socket portion; said plunger member having a non-circular part slidably and non-rotatably mounted in the socket portion; a

hook member carried by the plunger member; and a bundle of bristles removably secured to said hook member whereby'the plunger is utilized to seat the bristles within said socket and toexpel them therefrom so thata new bundle of bristles may be substituted therefor.

' 2. .A, brush of the character described comprising a two-part handle, one part being rotatably secured to the other; a bristle socket formed in the lower end of one part; a hollow screwthreaded portion in the other part; a non-circular plunger member having an enlarged screw threadedhead within said hollow screw-threaded portion; said socket part having a non-circular opening in which the plunger is slidably mounted and hook means on the lower end of the plunger adapted to be removably connected to a bundle of bristles so that the bristles maybe removed and new ones substituted therefor.

3. A brush of the character described comprising a bristle carrying handle portion presenting a flared socket at the lower end and having a cylindrical recess in the upper end; an upper handle section having a cylindrical extension mounted in said cylindrical recess in the bristle carrying portion; means connecting said portions together so that one may rotate with respect to the other; multiple screw-threads in the hollow portion of the upper section; a non-circular plunger having a screw-threaded enlargement mounted in the screw-threaded portion of the upper section, said lower section having a 11011-7 circular opening to receive. said plunger and prevent it" from rotating; a hook member on the lower end of the plunger. extending into the bristle socket; a bundle of fibers or bristles-removably secured to the hook member whereby the fibers or bristlesmay be seated-in the socket or expelled therefrom; and acoil spring in the upper end of the socket arranged to assist in expellingthe bristles.

.4. A brush comprising a hollow handle having a bristle socket; screw means in the handle having a member adapted to secure a 'bun-' dle of bristles in the socket; and a spring in the socket to expel the bristles therefrom. i

5-. In a brush of the class described, a handle having a bristle socket; a bundle of bristles composed of reversely bent fibers or hair; a binding band below the upper bent portion; a screwoperated plunger having a hook to engage the loop in the bundle of bristles and. pull it into the socket; and a knife blade in the handle projecting into the socket arranged to cut the binding band as the bundle of bristles is pulled home so as to render the bundle. useless after it is removed.
