MANICURING DEVICE Filed June 24, 1950 2 Sheets-Sheet 2 FIGS. 3 Z] 30 INVENTOE' By AT o N EYS Patented Jan. 9, 1951 UNITED STATE s PATENT OFFICE MANICURING DEVICE John Albert Chappuis, Neuchatel, Switzerland Application June 24, 1950, Serial No. 170,067 In Switzerland July 4, 1949 A further object of the invention is the pro vision of a manicuring device for trimming nails which is particularly well adapted to be manufactured by mass production methods so that the device can be made in a particularly inexpensive manner. Other objects of the invention will become apparent from the following description and claims, and from the following drawings, in which: Figure 1 is a side elevation of one form of manicuring device embodying the present invention and showing the mode of operation of the device. Figure 2 is a perspective'view of the device shown in Figure l with the various parts thereof detached from one another.

Figure 3 is a cross sectional view to an enlarged scale on the line 3-3 of Figure 1.

Figure 4 is a longitudinal sectional view of part of the nail-cutting element of the device depicted in Figure 1.

Figure 5 is a view similar to Figure 4 showing one of the stages element. a

Figure 6 is a plan view of part of the completed element shown in Figure 4, the view being taken in the manufacture of the article presents a novel and striking appearance.

Each body part is of substantially disc-like configuration comprising a fiat inner face l3 of annular configuration, the peripheral edge of each face being largely of part-circular con-' figuration as indicated at [4, each such peripheral edge being formed adjacent the face l3 and medially of the circumferential length of such edge with a recess IS, the base of which recess is formed with an arcuate groove l6 disposed a short distanceinwardly of the peripheral shown at I 8.

looking at the underside of that figure and being on a scale less than that of Figure 4.

Figures 7, 8 and 9 are views similar to Figure 6 showing three modifications. J

Referring firstly to Figures 1 to 3 of the draw,- ings, the manicuring device there illustrated comprises a body ll! of relatively flat and largely circular configuration, the body consisting of two identical body parts ll, 52, each conveniently formed by moulding the same in a suitable plastic, the two parts forming each body being moulded in a material of the same colour but preferably of dissimilar colours, for example, one a white-colour, and the other a red, green or other contrasting colour, so that the assembled .diametrically handle portion 25, the two handle portion being "along the length of parts are brought together edge l4, each groove being adapted when the parts are assembled, to receive one of the two longitudinal edges I! of the elongated-part-cir cular strip metal nail-cutting element which is Each body part II, I2 is formed adjacent the recess IS with a number of circular holes I 9 spaced apart equidistantly and symmetrically therecess, the edge of each of such holes which is more remote from the centre of the body part merging into the recess [5 so that this is'interrupted at positions corresponding to each hole l9, while each hole l9 extends inwardly of the body part beyond the inner wall 20 of the groove l6.

These holes l9 serve to permit of egress of the nail parings during the operation of the device.

Each body part I I, I2 is formed centrally on its fiat face [3 with a circular recess 2| so that when the two parts are assembled, the two re-'- cesses 2i collectively provide a housing as shown in Figure 3, in which 'a spare cutting element indicated at 22 in that figure may-be disposed with the element bent to a curvature greater than its natural curvature shown in Figure 2; so as to engage resiliently with the circular wall of the recesses 2| and thereby to be retained in position.

For "securing the two body partstogether, the annular flat face l3 thereof is provided in each case with an upstanding connecting pin 23 of 1 slightly tapered configuration, each pin being adapted frictionally to engage within a corre spondingly tapered recess 24 when the two body with the fiat faces l3 thereof face toface with one another. To facilitate operation of the device, each body part is formed on its periphery at a pOsition opposite to therecess IS with a thus brought into overlapping relationship with 7 one another when the two parts are assembled f together, and the opposed faces of these. handle portions are formed near the outer edge thereof with recesses 26 so thumb nail of the user the that by the insertion of the rebetween, the two body parts can be forced apart to permit when necessary of the removal and replacement of the of the user so that the pins 23 engage frictionally with their corresponding recesses 24,- thus effectively securing the parts together against movement when the device of use.

relative is either in or out Each body part is recessed peripherally at 21, 28 on each side of each handle portion 25, and

each recess 28 which is adjacentthe pin 23 is I provided centrally with a nail-cleaning part-29 adapted to be inserted at the back of the users nail in the known manner. from Figure 1, when the two parts u,

As will be apparent l2 are assembled, the two nail-cleaning parts 29 are spaced apart from one another so that either part may be used as desired.

'Z-As will be clear and from body parts ll, one another, that is to say,

from the above description an examination of-Figure 2, the two i2 are completely identical with either part may be formed from the same moulding die with resultant saving in production costs.

- Each body part preferably has its outer fac formed as a central cylindrical portion 38 surrounded by an outwardly tapered annular face 3!. as shown in Figure Mbeing formed peripherally circular rim 32 33 which may serve lar matter.

the inner edges '40 cut length of strip is then adapted to trim the users nail, trimming being effected by positioning the users finger in relation to the device as shown in Figure l with the flesh of the finger adjacent the nail engaging with the 44 of the body part of one side of the opening 12, so that the edge of the nail projects into the opening 42 for engagement with the cutting edge parts 13, and as the nail is'drawn along the length of the cutting element 18, the desired trimming is efiected, the nail parings falling out through the holes IS.

The trimming operation can be effected in several different ways, for example, by drawing the nail continuously across the cutting edge of one of the holes il in the cutting element, by draw: ing the nail along the whole length of the cutting element, or by turning the body so that the cutting element has in eiiect a rolling engagement with the edge of the nail.

In Figures 7, 8 and 9 are depicted alternative shapes to the holes M in the cutting element. These are formed in a manner similar to the construction already described.

The manicuring device particularly described above is extremely convenient to handle, can readily, be disposed in the pocket or handbag oi the user, it presents a neat appearance and can readily and inexpensively be made by mass pro duction methods, while when a cutting element has become worn, it can readily be replaced.
