MANICURE FILE.

Application filed September 24, 1919. Serial No. 326,020.

To aZZ whom it may concern:

Be it known that 1, PAUL HARTLEY, a citizen of the United States of America, and resident of Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Manicure Files, of which the following is a specification.

This invention relates to a manicuring instrument and more particularly to a manicure file.

So far as I am aware, manicure files have heretofore been provided with an abrasive or cutting surface coextensive with the width of the file. This construction renders the edges of the file rough and sharp so that when the file is employed to file the end of the nail this sharp edge coming in contact with the flesh of the finger tip often produces annoying and painful cuts or abrasions. The principal object of the present invention is to obviate this objectionable feature by providing a manicure file having its edges so formed that the file cannot cut the fingers or injure the tip of the nails.

I will now describe the invention in connection with one specific embodiment of the genus of my invention. In the accompanying drawings,-

l igure 1 is a view of my improved file;

Figure 2 is an enlarged transverse section taken on line 22 of Fig. 1;

Figure 3 is an enlarged perspective view of a portion of the file; and

Figure i is a view showing the manner in which the file is employed.

Referring to the drawings and particularly to Fig. 1, my improved file comprises a tapering blank having a smooth portion 1, serving as a handle, a pointed smooth tip portion 2 which serves as a nail cleaner and a portion 3 formed with a cutting or abrasive surface in any suitable manner well known in the art. One edge of the blank is provided with a bead l coextensive with the abrasive portion of the blank, and the other edge is provided with a similar bead 5 ex tending through a portion only of the abrasive portion of the blank.

The beaded edges of the blank are preferably cylindrical in configuration and of slightly greater thickness than the abrasive portion of the blank as most clearly shown in Fig. 2, and may be suitably polished to provide a perfectly smooth surface for contact with the flesh.

As most clearly shown in Fig. 1, the bead 5 is omitted from the edge of the blank as at 6 for a suitable distance adjacent the tip of the blank to permit the file to be more readily employed in positions around the nails where the bead would interfere if extended to the tip of the blank.

The file may be provided with any suitable form of handle such as a wooden, celluloid or bone handle attached to the blank in the region of the smooth portion 1, or the smooth portion may itself serve as a handle as described.

The improved file is used as indicated in Fig. a, the abrasive portion 3 of the file serving to finish the edges of the nails, the beaded edge of the file resting in contact with the fleshy end of the fingers beneath the tips of the nails. In addition to protecting the finger the beaded edges further prevent the file from slipping laterally from the nail and should the file so slip the edge of the file cannot nick or otherwise disfigure the nail because of its smooth edges. For use by a professional manicurist, the tip 2 of the file may be rounded rather than pointed. The protective beads i and 5 may also be extended the whole length. of both edges of the file,

While primarily my invention is applicable to manicure files it is within the broad purview of my invention to provide files suitable for work upon wood or metal with flanged or beaded edges to prevent them from slipping from the work.

I claim:

A manicure file formed from a thin sheet of metal having an abrasive surface extending through a portion only of the width of said file, one of the marginal portions of said file being thickened throughout the entire length of the abraded surface and the other marginal portion of the file being thickened throughout a portion only of the length of the abraded surface to form smooth beaded edges.

Signed by me at New York, N. Y., this 20th day of September, 1919.

PAUL HARTLEY.
