V the sheath being broken out, and

inina, citizen of bristles from being 20 KICI-IIIBEI'YAN'AGIHARA, or SAKAI, OSAKA-EU, artisan, .ASSIGNOR o sAK-ni KAKo onnLULoID KwArsHA, Lrn, on similar, JAPAN, a co aroaerrouor APAnNwr'nornc'rnn roo'rnnnus i. f g f Tc all whom it may concern:

Be it known that I, Kiorrrnnr YANAGI- Ja 321.11, residing at No. 53, Higashi-itchome, fZita-hatago-cho, Sakai, Osaka-F11, Japan, have invented certain new and useful Improvements in Protected Toothbrushes; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will en-' able others skilled in the art to which it appertains to make and use the same. I f

This invention relates to brushes such as tooth brushes, and particularly to means for protecting'the bristles thereof before the brush is actually used and also afterthe brush has been put in use.

The principal object'of the invention is to provide a means that will protect the damaged and soiled while the brush is in transit, as for example,

when it is exported to various countries and climates. Another object of the invention is to provide ameans for protecting the bristles of the brush while the brush is in transit and before it is actually used that can be utilized thereafter as a dust guard to protect the bristles while the brush is not in use. I

In carrying out my invention, 1 provide a sheath or guard of celluloid or similar material for inelosing the bristles, one end of the sheath being closed by a detachable piece of celluloid or similar material Which may be torn off or otherwise removed when the brush is to be used. Thereafter the remaining part of the sheath may be utllized as a dust guard to inclose the bristles while the brush is not in use.

The objects and novel features of myinvention will be apparent from thefollowing description taken in connection with the accompanying drawings which show a tooth brush embodying my invention, and in which- Figure 1 is .with the sheath attached thereto, a part of the brush,

Fig. 2 is a side elevation of showing the sheath applied thereto and in section. V In the drawing, d designates the handle of the tooth brush, carrying the bristles d.

4 a is the body of the sheath and consists of a a perspective view of the brush hollow body of celluloid, paper orilike .7

terial, adapted tocompletely'inclosethe end of the handle and the'bristlesd thereon. j

The end piece Z), ofthefsamematerial as Specification of Letters iP-atent. qpatenlt dg m-g,1920;:

the sheath a, is attachedto the latter as by welding it in place in the open end of the body a after the body a has been placed over for shipment and are prevented frombeing solled or damaged. The end piece 6 is pro Q the end of the brush so as to: inclose the bristles. .Vith the end piece Z2 welded in place, the brlstles are completelyinclosed vided with a tongue 0 that projects outwardly along the handle of the brush and is fastened to the handle by. aband g, The

end piece 7) serves a temporary purpose only a and is readily detachable from the body'a of the sheath by pulling the tongue 0, which latter may be readily detached by breaking or otherwise unfastening the band 9. The welded seam betweenthe end piece 6 and the body a of the sheath serves as a weakened tearing or rupturing line for detaching the end piece 6. When the end piece I b has been removed, the sheath or the partia thereof maybe utilized as a dust guard to keep the brush sanitary during the time when it is not in use.

That I claim is:

1. The combination with a ing' a handle carrying bristlesorthe like, of a sheath or guard inclosin'gsaid bristles and having an end piece secured theretoand to brush compris- L the brush handle to hold. the sheath in place while the brush is in transit and before itiisj used, said end piece being detachable when the brush is to be used, and said sheath be:

ing thereafter adapted to be used as a dust guard for the brush.

2. The COIIllOlIlfttlOIl with. tooth brush 9 comprising a handle carrying bristles, of a ,sheath made of celluloid, paper or'the,like-,= protecting said bristles, said sheath having a detachable end piece closing one en thereof, said'end piece comprising" a tongue, and means whereby said tongue issecured to said handle. i

3. A sheath or guard for tooth brushes and the like, comprising a hollow receptacle adapted to receive and completely inclose the'brushing' means or bristles of the brush,

said receptacle having an end wall that is constructed and arranged to be detachedloo.

i from thel bocly of the receptacle, such .re-

cepta cle' after having its end Wall detached being usable as 'a-dust guard for the brush.

adapted to receive and completely inclose the brushing means or bristles of the brush,

' 4. A sheath onguarcl for tooth brushes and the like, comprising a hollow receptacle said receptacle having a detachable end wall jprovicled'with a tongue adapted and arranged to be, secnrecl togthe handle of the brush, such receptacle being .usable as a guard for the brush after having its enclwall' and tongue detached. v a In testimony whereof I hereunto aflix my KICHIBEI'YANAGIHARA.
