N. G. E. JOHANS SON APPARATUS FOR CUTTING FINGERNAILS 2 Sheets-Sheet 2 Filed Dec. 21, 1943- mm mwnma* UNITED STATES, PATENT OFFICE films APPARATUS CUTTING FINGERNAILS Nils Gustaf dohans son, Orrefors, Sweden- Application December 21, 1943, Serial No. 515,179 V In Sweden November 17, 1942 3, oi (oi. 30 124) The present invention relates to apparatus for cutting fingernails andhas for its objectfto produce such an apparatus which in usewill prevent thesc atte'ring of .the'nailfc uttings.

Another object of the invention is t pre ate a naiTcutterof a cbmpact construction and a handy shape and inwhich the cutting'means is protected insu'ch mannefthatftlie apparatus can be carried'in th pocket.

A further object or the'invention a nail cutter in 'which'the'hail'is guidediiuring the cuttingbp'erationjand the fin'geretipsai'e protected, 'so that there; will. bel'1'io" risl{of 'l'tt'ng three embodiments of the novel nail. cutter, illustrated, by way of e'xample jintheaccompanying drawings, in which: I v Q Figs: 1-6 relate to theQfirstembodirrientij ;I Fig. 1 is an endviewlof the cutter; Fig. 2 is aside View} 7 Fig.3isatop view; s v Fig. 4 is a sectional view onthe line IV.IVin Fi -5; r Fig. 5 is a sectional view.on the line AIL-Vin Fig.4;

Fig. '7 is a sideview of the apparatus; j

Fig. 8 shows a section on the line a Fig. 7;

Fig. 9 is a perspective view of the apparatus according to the third embodiment. The nail cutter according to the presentinvention, comprises, in its generalflcombinatio'n, a box adapted to receive the nail cuttings'a'cutter mounted inside the box close to at least one section of the wall of the box, and'a .slot provid'ed in said wall section across the "edge of the cutter, to allow the insertion of a nailfagainst the cutter and to guide the nail during the cutting operation, said wall section forr'ninga guard member for the cutter. 1 I In the embodiment shown in Figs. 1-6.: the box I is of a flat square shape and has a cover 2 on one of the two flat sides. The box'and ,thccover are produced of sheet metal or the like but may also be cast or presseohior instance ofBalgelite. The cover 2 is connected tot he box l' by n eans is to produce C fof hinges 5 and is provided with a spring-pressed 6 of usual type. In one of the short walls 15 a. .slot 3 is provided which extends from the cover 2 to the opposite flat side, viz. the bottom '.of the box. The'slot 3 extends also through the cover, as shown in Figs. 2 and 3. Inside the box and behind the slot 3 a cutter 4 is mounted parallel to the wall I5 and close to the same. Thus, the wall 15 forms a guard plate for the cutter. Preferably, this guard wall is slightly ,coricave'on the outer side, to facilitate the guid- Zing of the apparatus against the finger tip (compareFigsll and.2)l I x I Preferablythe cutter 4 is mounted in such way that it canfbe exchanged for a new cutter when 'the edge has become blunt. In the embodiment shownin Figs. 1-6 the cutter 4 consists of an ndless's'teel band one edge of which is made sharp) This steel band is mountedin the box so as to form a cylinder and may be rotated to advance new portions of the edge in position behi'nd the slot 3., To retain the steel band in the cylindrical shape corner pieces or shoulders 8 areiprovided in the .box, which pieces are formed with 'arcuat'e bearing surfaces for the cylindrical cutter and, thus, constitute guiding members for in Figs. 1-6, this operating handle 9 consists of a milled pin connected to the cylindrical cutter by means of a diametrical plate spring II) which by. terminal projections is removably inserted in apertures in the cutter band, the arrangement beingsuch that the cover 2 when in closed position, will hold the back or rear edge of the cutter against ,the bottom of the box by the aid of the operatingjmember 9 and the resilient strip H]. 'Ihus, unintention-al rotation of the cutter is preventedgbut after opening the cover 2 it is possible, by rotating the operating member 9, to adjust the cutter in relation to the slot, so that 'difierent portions of the cutter edge can be brought into position behind the slot as the edge of the cutter becomes dull. When the cutter has become blunt over the whole edge, the spring I0 kisily can be removed from the cutter and ins'erted in a new cutter.

.,The slot 3 and the cutter 4 may be arranged in such manner in relation to each other, that th Edge portion lying behind the slot, is at right.

angles to the longitudinal direction of the slot, as illustrated by the line a-a in Fig. 3. However, the arrangement also advantageously may be such, that the edge portion lying behind the slot .forms an acute angle with the longitudinal direction of the slot, as indicated by the line bb in Fig. 3. When a cylindrical cutter is used this may be attained by arranging the plane in which the circular edge line of the cutter lies, somewhat slanting (according to the line b-b in Fig. 3), but instead the slot 3 may be inclined correspondingly.

The box comprises internally the space H in which the nail cuttings are collected. To prevent these cuttings from falling out through the slot 3, the portion of the slot not closed by the cutter 4, may be closed by means of a weak resilient plate I2 provided inside the short wall (the guard plate) la and secured, preferably, to the adjacent short wall (see Figs. 4 and 6). This resilient plate l2 yields to the pressure of the nail when the nail is inserted through the slot, but then prevents the nail cuttings from falling out through the slot. Said plate I2 or a similar member needs not to be resilient but may also be firmly mounted at a distance from the internal surface of the guard plate, so that it does not prevent the cutting operation but prevents the nail cuttings from falling out.

The nail cutter according to the invention may be combined with a nail-file 1 formed as the blade of a knife and provided with a nail-cleaner. This nail-file is mounted in such way that it can be clapped into the box, as shown in Figs. 4 and 6. For instance, the nail-file may be mounted in a corner piece 14 which may be a separate member or may be formed unitarily with the adjacent corner piece 8. Also other known tools may be arranged in a similar way.

The manner in which the nail cutter according to the invention is used will appear from the foregoing description and the drawing.

In the embodiment shown in Figs. 7 and 8 the box 2| is of tubular shape and provided with a cover 22. The parts 2| and 22 are produced of Bakelite or other like materials which can be pressed or cast. The cover 22 is screwed into the tubular box. A slot 23 is provided longitudinally in the cylindrical wall of the box. If desired, a plurality of such slots may be provided. The external side of the cylindrical wall in the extension of the slot has an arcuate shape corresponding to the shape of the nail. The tubular cutter 24 is held between the cover and a shoulder in the box. After removal of the cover the cutter can be rotated into another position and, if necessary, exchanged for a new cutter. A portion 24a of the cylindrical cutter is formed as a nail-file, and the tubular wall of the box is provided with an opening 26 in front of said nail-file, through which opening the nail may be inserted against the nail-file. A nail-cleaner 21 may be provided on the external side of the bottom of the box. When clapped down the cleaner rests in a recess in the bottom.

In the embodiment shown in Fig. 9 the box 3| is in the shape of an oblong hollow handle provided with a cover 32. A slot 33 is provided in the end surface, viz. the bottom surface of the box. A cutter 34 consisting of a square plate, is mounted in a recess in the bottom end wall of the box, close to the slot. The recess may extend through the whole width of the handle, and the cutter may be held by friction in the recess 4 or by spring-pressed locking means or the like.
