'9 Glaims. 1 This invention relates primarily to manicuring andv nailV cleaning instruments and .the like,zbut may be employed for the uses to which it-is adaptable.

vI-Ieretofore-many attempts have ;been made .to

provide a manicuring instrument which .coui'd efiicient instrument.

One object -ofthisinventionis .toaprovideiia portable instrument which will-enable .thefnails to be cleaned efiiciently by .providing a measured,

vlimited and accurately.controlledsourceof cleaning fiuid.

.i Another .object of .the invention .is toprovide a leakproof container for aliquid cleanerin .combination with. ani. efficientl-means for vCleaning thel nails.

Another object .of the invention is tozprovideza manicuring instrument .containing cleaning fluid which may .be easily Aand safely. carried..in',the

`pocket, and used. at any'timeas desired. .Other .objects and advantages will lbeapparent.

The invention is illustratedin the accompanyingdrawing, in which the-figura' isa longitudinal,

.theannular ring. 3.and is fully closed by the` end :piece 4 and frictionally heldin .placenby being forced .over .the 'stepped annuiar zshoulder V'5 which is a part of the lower-endof the reservoir I.

The end 'piecelhas running through itscenter .and slidable thereinzia. hollowV tube `6 .which has a bluntclosed end at 1, and is pierced. by minute -orifices 8 at its ;lower extremity; vTube 6:'has

attached near to the lower end small bristles 9 which surround the minute orifices 8. At. its.`4

In this dry condition it may be used for brushing and cleaning the nails without the aid of a detergent liquid. The liquid may be a thin soapy solution or a volatile fiuid of the dry-cleaning order, and if the former the nailsj may be dried bythe use of absorbent paper or'cloth.

It will be understood that the frictional coaction between the tube 6 and its integral parts and i' the parts through which it passes issufficient to DTBVBII Slpping When the instrument, is rotated to cause rotation of the brush, i

l. ture and .movable therethrough, said member having a recess therein at the part which extends -through thev said diaphragm opening and an Various changes in the details lof construction of the instrument shown and described and additions thereto may beHmade without departing from the scope of theinvention. Thus the terminal '1 may be sharpened and/ orextended if desired and used as' a very effective, cleaner to-'dislodge dirt or other foreignmatter; and'the improvements may be adapted forluse with adentifrice for Cleaning the teeth instead of as a manii cure instrument. The .brush may be used dry or with moisture from the outside in either case.
