INSTRU'LENT FOR SEPARATIN'G THE OIJ'TICLE FROM THE NAILS.
Specification of Letters Patent.

Application mm January 18, 1908. Serial No. 411,399.
T 0 all whom it may concern:
Be it known that 1, ROBERT AMoRY, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Instruments for Separating the Cuticle from the Nails, of which the following is a specification.
This invention relates to an improved instrument for separatin the cuticle from the nails. The use of sudh an instrument for separating the cuticle and flesh from a growing nail, when the instrument is made of metal is likely to cause onychia, whitlow and ingrowing toe-nails, especially when the cuticle or flesh from the soft tissues is attached to the nail-and, when this elongates with the growing nail, ispulled away from the surrounding flesli making a fissure, thus ex osing the wound to absorbing pus or other de eterious liquid by contact with unclean instruments, materials or articles.
The object of this invention is toobviate this risk to the user and to this end an instrument of wood or other vegetable matter is charred or carbonized atone end thereof to sterilize the wood and is then moistened in water, referably anti septic, Which will soften t 1e charred substance and prevent the cutting of the cuticle or flesh at the side of the nail or under the separatednails at the ends of fingers, thumbs or toe-nails after the wood or other vegetable matter is charred and the end moistened in water, all the free and superfluous charred material is removed by friction so as to leave the said end smooth and clean.
It is more desirable, convenient and easier of mani ulation to use a conical smooth oint w en separating the cuticle or flesh mm the nail, but the conical point is not absolutely essential to the invention hereinafter described. It is, however, very essential that the end of the instrument shall be clean and sterilized. Charring or carbonizing of the wood may be done in a variety of ways, either by igniting the-same and aftervvards inoistening or by subjecting the same #Ito the action of acids or other medicaments to produce the charred sterilized l The invention consists in the instrument hereinafter described and set forth in the claims.
The figure of the drawin s illustrates a side elevation of a desirable form of my imroved instrument for separating the ,cuticle om the nails. I
In the .drawings 1 is a handle'of any con venient form having a flange 2 thereon which separates the handle from the stem 3 said stem being recessed to receive the shanlt 4 of an end piece 5. The end piece 5 is prefer ably conical in shape andformed of wood or other vegetable material. Said end piece 5 ma be made in one piece with the stem 3 an handle 1, but preferably, is made de-' tachable, as shown 1n the drawin so that the same handle can be used wit number of different end pieces, which end pieces may be made-of various shapes and user. The end piece 5 is sterilized before using in the following manner: It is'first ignited and allowed to burn until a certain amount of the end piece has become charred and is then plunged into a lass of antise tic water, whereby the furt er charring o the wood ceases and the carbonized ortion of said wood ismoistened. Said carronized ortion of the wood is then rubbed with a clot to remove the superfluous carbonized material; leaving the end of the wood*charred'smoothf and of a conical form and in condition'te be used for the )urpose hereinbefore set forth, Without any danger of cutting or injuring the flesh and without any danger of transferring. noxious or su purating matter from the in; strument to t e flesh of the person using it and so clean that the same will not soil the fingers or toes of the person usin g it by reason of any free carbonized matter.
ment in the manner hereinbcfore set forth I do not confine myself to the charrin t e same by ignition, as it is evident t at the wooden end piece may be charred by th'e use water which is used to'moisten'the 1nstru-. ment after; the charting operation-.-may be supplied with an alkali to neutralize any exsizes to suit the convenience or desire of the While it isprefcrable to char the instru a large sir.
of sulfuric or other acid substance and the o cess of said acid the resulting instrument be- I piece having a stem adapted to fit in a recess ing thus artialiy charred, as in the manner 'provide'din said handle. hereinbe ore set forth. In testimony whereof I have hereunto set Having thus described my invention, what my hand-in presence of two subscribing Wit- 5 I claim and desire by Letters Patent to senesses.
