SIMONDESMONDTURIJY, OF FAIRVILLE, NEWBRUNSWIOK, CANADA, AssIGNon OF ONE-HALF To T. s. sIMMs a COMPANY, LIMITED, or FAIIWILLE, NEW BRUNS- WICK, CANADA, A CORPORATION OF CANADA. y

To all 1v/1.0m t may concern.'

`Be it known that I, SIMnoN DESMOND PURDY, :Iy-citizen of the United States `of America, residing at Fail-ville, St. John county, New Brunswick, Canada,khave .1n vented` icertain new and useful `Improvements in Brushes, of which the following is a specification.

My invention relates to brushes, and particularly to shaving brushes, the Object of my` invention being to provide a shaving brush of the tourist or traveler' type having `an improved generalconstruction, and particularly an improved housin'gconneotion between the brush `ferrule properand the handle or casing of the brush.

In the accompanyingdrawings* I Figure 1 is a longitudinal section througl a brush in which my invention is embodied in 011e form; i

Fig. 2 is a section on the line 2--2, Fig. 1;

Fig. 3 is a partial `longitudinal section showing the brush ferrule housed within the casing; and

Fig. 4 is a section on the line L -4c, Fig. 3.

In the present construction the brush coinprises a tubular casing 5 of lnetal, Celluloid, hard rubber or the like, within which is accommodated the ferrule 6 carrying the knot 7 oi bristles Jforming the brush proper. The stub end of the bristle knot 7 may be cemented directly to the ferrule 6, or to an independent ring 8 secured in any suitable fashion inthe outer end of the ferrule 6. As indicated, the ferrule is of a slightly irustdconical shape at the brush end. The end 9 of the casing is likewise drawn to t'rusto-conical shape to limit the extent to which the ferrule may be pushed outward at this end of the casing.

In order to maintain the ferrule in its extended position, indicated in F ig. 1, so that the brush 7 may be put to use, I provide a pair of studs 1() projecting through holes in opposite sides of the ferrule, and normally pressed outward by an interposed coil spring 11, which bears against iangesV 1Q on the studs. A disk 13 closes the inner end of the forlule and may be secured in position in any suitable way. To receive the outwardly projecting ends of the studs, the inner face of the casing is provided with a pair of arcuate recesses 14 arranged diametrically opposite each other, and of a lBRUsIIQ Specification of Letters letent. I Patentd J ly 19, 1921, Application led January 7, 1921; Serial No. 435,717.

depth land width suliicient to receive the studs 10. To free the studs from these re cesses 14, it is obviously only necessary to rotate the ferrule to a slight extent, thereby causing the studs to run up the inclined bottoms of the recesses to the interior surface of the casing 5. The ferrule may then be pushed inward in the casing, the studs bearing against the inner surface thereof, and serving by their frictional engagement therewith to maintain the brush housed within the casing, as indicated in Fig. 3. The end 9 of the casing is intentionally left open to insure ventilation of the bristles and thus prevent rotting of the latter, should they be housed within the casing while wet.

The opposite end of the casing is tapped to "receive a stop ring 15 screwed therein and having a central opening 16 to permit the insertion of a finger to advance the ferrule to the position shown in Fig. 1. If it is desired to remove the bristle bunch for cleaning, the stop ring 15 may be unscrewed and the ferrule 6 withdrawn at this end of the casing.

The construction as a whole is extremely simple, while at the same time the casing effectively retains and houses the brush when out of use. Its ready extrusion from the casing by the finger eliminates the necessity for operating slides, pushers, etc., which commonly get out of order or become choked with soa-p.

Various modifications in detail and form of construction will readily occur to those dealing with the problem. Variations within the purview of those skilled in the art, will be understood to fall within the scope of what I claim as my invention.

l. III a brush of the type described, a tubular casing having an arcuate notch formed in the inner face of its wall, a brush-carrying ferrule slidable within said casing, and a latching element carried by the ferrule and spring pressed outward to engage said notch and thus to hold the ferrule in brush-exposing position.

2. In a brush of the type described, a tubular casing, a brush-carrying ferrule slidable within said casing, and coperating readily freed latching elements for the ferrule and casing, said elements being completely housed within the casing and serving to hold the errule against longitudinal displacement at one end of the Casin said latching elements being disengagea le by relative rotary 'displacement oi the parts.4

3. A brush of the type described, comprising a tubular casing open at both ends havev ing an interior recess adjacent one end, in combination with a brush-carrying ferrule longitudinally slidable Within said casing, and spring means carried by the ferrule and detachably engaging said'recess to maintain the brush in extendedposition, said means engaging the interior of the Ycasing in unlatched position and serifing to frictionally maintain the brush housed Within the casing.

4t. In a brush of thetype described, a tubular casing, a brush-carrying ferrule sliding Within said casing, spring means carried by .theerrule andr frictionally engaging the interior or*V the casing to maintain the brush housed therein, means limiting the outward displacement of. the errule at one end of the casing, andmeans at said end of the casing coperati-ng with the spring means ot the ferrule to. holdi the latterin brushexposing position, said latching means being readily freed` byv relative rotation of the ferrule and casing to permit the 'errule to be longitudinallydisplaced within the casing to brush-housing position.

5. In a brush of' the type described, a tubular casing, ra brush-.carrying ferrule rotarily and longitudinally displaceabl'e iin the casing, friction means holding the fer-rule `casing to hold the ferrule against longitu dinal displacement in brush exposing position.

6. In a brush of the type described, a tubular casing open at both ends, a brushcarrying errule slidable within the casing, means at both ends oi the casing to prevent the escape of the errule and concealed spring means readily freed by relative rotation of the casing and errule for holding the brush against longitudinal displacement in brush-exposing position at one end of the casing.

7'. In a brush. of the type described, a tubnlar casing constrieted at one end, a stop ring secured to the other end of the casing, said casing having a pair of arcuate notches on opposite sides of its inner surface adj acent one end of the casi-ng. in combination with a frusto-eonical ferrule longitudinally slidable in said casing, and spring studs carried by said ferrule and engaging in said arcuate notches to maintain the ferrule in brush-exposing position at the eonstrieted end of the casing.

In testimony whereof I have signed my name to this specication.

SIMEON DESMOND PURDY.
