MANICURING IMPLEMENT Filed April 13, 1955 INVENTOR.

Patented Nov. 5, 1935 UNITED STATES PATENT OFFICE MANICURING IMPLEMENT Roland J. Poux, Meadvllle, Pa. Application April 13, 1935, Serial No. 18,165 3 Claims. (01. 30-23) My invention relates to manicuring implements and more particularly to one-piece nail .files.

An object of my invention is to provide an.

improved one-piece nail file having abrasive or filing surfaces suitably designed for most effective work, and which is very cheap to manufacture. More specifically it consists of a single sheet metal stamping having grooves running lengthwise thereon with abrasive surfaces formed on the concave portions of the groove. I am aware that filing surfaces in grooves adapted to receive the end of a fingernail are old, and make no claim to the same broadly, but I believe I am the first to devise a file consisting of a. single elongated piece of thin sheet metal in which grooves are embossed along the edges, which grooves have the double function of providing surfaces for the most eiflcient filing and at the same time, strengthening ribs to resist flexing. A certain degree of flexibility is not objectionable but if made of thin metal a file wouldordinarily be too flexible. My improved file, while providing grooved and other filing surfaces of the most effective design for goodmanicure work, may be made very cheaply from a simple sheet metal stamping. The grooves may be embossed and the filing surfaces formed by suitable rollers.

In the accompanying drawing I have shown for purposes of illustration one embodiment which my invention may assume in practice. In

the drawing:

' Fig. 1 is a. plan view of my improved file; Fig. 2 is a side view: Figs. 3 and 4 are cross-sections on lines 3-3 and 4-4 respectivelyof Fig. 1; and

, Fig. 5 is a fragmentary sectional view il1us trating how certain of the concave filing surfaces may be used.

The file illustrated is a narrow, elongated relatively thin piece of metal having the flat handle portion 6, a central filing portion 1, and a pointed end and sharpened knife edge 8.

The sheet metal piece is embossed to provide grooves 9, I along the side edges and extending throughout the length of the filing portion. The walls of the groove may be of approximately the same thickness as theoriginal sheet metal. This embossing operation also forms strengthening ribs ll, I2 of corresponding shape and size to the grooves 9, l0 respectively.

The filing or abrasive surfaces may be formed in any suitable known way, as for example, by a knurled roller, which provides the knurled filing surfaces shown herein. The concave surfaces of the grooves 9, l0 are provided with such filing surface. The fiat body part l3 of the filing portion may be left smooth or provided as shown herein, with additional filing surfaces on opposite sides thereof. The file teeth preferably extend-over the inner side surfaces l4, l5 of the ribs H, lb 2 respectively, to provide additional concave a rasive surfaces at the c ribzswliliih the body part l3.- Jun ture of the ustrated in Fig. 5 the grooves 9 the surfaces l4, l5 maybe used for fili ng tlg: finger nails. The concave surfaces will tend to give a smooth or rounded finish on the nail and at the same time the groove or rib as the case may he, tends to assist in guiding the finger nail during filing.

It will be noted that the portions of the file which come in contact with the flesh during use have smooth surfaces indicated by the numerals 2|, 22. There is accordingly no likelihood of the user injuring the fingers.

The handle portion may be enhanced in any desired way such as by the addition of pieces of wood or bone. It is shown herein as provided with the central strengthening rib Hi. This provides opportunity for additional abrasive surfaces ll on the groove and I8, I 9 on the rib.

At the extreme end of the handle portion there may be formed a cuticle tool of any suitable design such as illustrated at 20.

While I have shown and described in this application one embodiment which my invention may assume in practice, it will be understood that this embodiment is merely for the purposes of illustration and description, and that various other forms may be devised within the scope of my invention as set forth in the appended claims.

What I claim' as my invention is:

1. A nail file consisting of an elongated nar- 40 row flat piece of sheet metal having a groove embossed along one of its side edges and extending throughout the length thereof with the embossed portion forming a. strengthening rib on the side of said file opposite said groove, an abrasive surface formed on the concave portion of said groove, and a second abrasive surface formed on the concave surface provided at the juncture of said rib and body portion of the file.

2. A nail file as set forth in claim 1, wherein the flesh contacting portions adjacent said abrasive surfaces are smooth.

3. A nail file consisting of an elongated flat piece of sheet metal having a handle portion at one end and an elongated filing portion at the other end, said filing portion having grooves along its opposite side edges formed by transversely bending the sheet metal, whereby the walls of said grooves have substantially the 5 same thickness as the original sheet metal each or said grooves being relatively narrow, said filing portion also having a fiat st'irface between said grooves, and abrasive surfaces formed in the concave side of said grooves, the walls of said grooves also providing strengthening ribs to permit only limited flexibility of the file.
