sHAvING BRUSH; 'i I AApplication filed June 2A,

This invention relates to shaving brushes. A principal object is to provide a construction in which the knot is securely locked in the ferrule and in which the ferruleis so xed 5 in the socket of the handle as to prevent either endwise or turning movement of the ferrulel relative to the handle; to provide a construction of the character last referred to, in which the ferrule is so designed that after the knot is in place in theferrule, an effective interlocking bond will take place between the knot, ferrule and cement in the hollow handle; to provide a construction of the above character in which portions of said cement vare interlocked with the crimped or split portions or fins formed on the inner edge of the ferrule; to provide a construction which permits of the use of a one-piece handle which can be l formed in any desired configuration and made to resemble, if desired, either a one-piece or Va multi-piece handle; to provide a construction which is economical to manufacture and in which the parts are not loosenedv relative to each other. and in general to provide a con- 5 lstruction of the character last referred to.

The utility of the invention as well as other objects and advantages will be more apparent from the following description, reference be-y ing made to the vaccompanying drawings, in which Y Fig. l is an Ielevational view of the handle, ferrule and knot. with a fragmentary portion of the handle in brokenaway vertical section.

. Fig. 2 is a vertical sectionall view showing the various elements in assembled position.

, Fig. 3 is a cross sectional .view taken on line 3-3 of Fig. 2. .i

Fig. 4 is a perspective view of the ferrule.

Fig. 5 is a bottom face view of said ferrule.

Referring more particularly to the drawings, l designates a handle which, as a feature of the invention, may be preferably made of one piece, the closed end being integral with the body of the handle andthe other end open to receive the ferrule, designated as a whole 2. The particular conguration of the handle shown in the drawing is merely illustrative and the style may be modiiied as desired. The ferrule 2 may be of metal and may be provided at one end with a bead 3. The knot 4 is formed of suitable bristles as is well known to those skilled in the art. The inner end of this knot which is inserted inthe with suitable cementitious ymaterial such, for

ferrule 2 from vthe plain end may be coated instance, as rubber cement, and after the knot is in place in the ferrule, additional rubber cement may be added if desired. Either then or before the knot is inserted, either by hand or by suitable machinery, the inner end of the ferrule, that is the end opposite to the bead 4, maybe suitably slitted and the walls adjacent the slits bent inwardly to form the tongues 5, thereV being three of these tongues illustrated in the drawings. Itis obvious, of course, that there may be any number, as desired.

The hollow handle 1 may now be filled to f the extent desired Vwithv suitable cementitious material, as for example Portland cem-ent, or thelike, it being necessary to utilize a cement which produces a very rigid structure upon setting. The handle may then be stood on its closed end and the ferrule and knot assembled as heretofore described-may be then insert-ed into the open end of the handle. y The cement while stillin wet or plastic state iiows down into the ferrule and around the curved split tongues 5, asthe cement sets it forms a'` bond with theinner end of the ferrule andV 80 `particularly with the cur-ved split lfingers 5 heretofore described. Preferably the outer periphery of the ferrule may be provided i i with small lugs so shaped as to form wedge-iY like elements, facilitating frictional engagement with the inner periphery of the handle when the ferrule is inserted inthe socket in the handle, these also perform the function of Y' holding the ferrule and knot yfirmly in the handle while the complete brush is turned up. side-downallowing the cement to flow com?- pletely in and around the prongs of the fer-V rule and harden while in this position .with-.g out any of it leakingthrough Vthe beadl for.v tiltingthe knot and ferrulefrom a straight` line with the handle. t s From the foregoing itwill be apparent that I obtain a very effectivev locking engagement between the ferrule and handle, preventing eitherendwise or turning movementof either relative to the other and formingvat the same time a rigid cemented locking engagement in a very economical and efective'manner.

vBy making -slots of appreciable width whereby the cementitious material will have an opportunity-to flow between the inner wall 75v i position of the brush is then reversed and the of the handleand the walls of the tonguesV Y .in such a manner asto form an effective lockformeel on saiclV err'ule` and a ee1nentitious filler in the hollow Vhandle forming aninterlocking hond with saiel tongues.
