DRY- S HAVING DEVI CE Filed Dec. 31,1937 7 Fig.4

o w o H w PatentedNovrZl, 1939 UNITED STATES 2,181,038 nnr-smvmo nnvl'os Leopold Wimberger, Vienna,

Austria, assignor to L. Wimberger Kommanditgesellschaft & 00., tfiiititent-Verwertungsgesellsclntft, Vienna, Aus- Application December 31, 1937, Serial No. 182,871 In Austria December 10, 1937 1 '10 Claims.

The invention relates to apreferably electrically operated dry shaver, consisting of an outer shear-plate and an inner shear-member cooperating with the outer shear-plate, the outer 5 shear-plate having in its middle part a plurality of .openings of about the same diameter in all directions and, on both side parts, rows of crossslots and the inner shear-member having a platelike surface pressed to the inner surface of the outer shear-plate and having also cross-slots, whereby openings of the above mentioned form may also be provided.

One object of the invention consists in that at least a part of the cross-slots at least 'of the outer shear-plate, moving on the skin, are united with at least a part of the above mentioned, preferably circular openings, the diameter of these openings being greater than the width of the cross-slots. The inner ends of the cross-slots are thus provided with circular enlargements.

As a further object of the invention the inner shear-member is provided with longitudinal bridges by which are connected the cross bridges v separating the cross-slots. -By way of examplesseveral forms of the invention are illustrated in the drawing. Figs. 1, 3.

5 and 6 are plan views, illustrating the surface of the outer shear-plate; Fig. 2 is a plan view of the surface of the inner shear-member; Figs. 4 80 and 7 are cross-sections of the upper part respectively of a detail of the shear-head.

In all figures l designates the outer shearplate and 2 the inner shear-member. Openings 4 of preferably circular form are provided in the middle part of the outer shear-plate I; on both sides of this plate are provided short cross-slots 3, operating as guiding members forthe hairs and as primary shearers. These cross-slots lextend directly to. the of which is greater than the width 5 of the crossslots Each of said cross-slots thus has acircular The effect of enlargement at the inner 'end.

the cross-slots maybe improved by taperingthe free ends iii of the same (see Fig. 3). Hairs lying on the skin may be, with greater effect, introduced in the cross slots by a step-like portion l3 (Fig. 4 or'7). 1

As a result of the union of 'the cross slots 3 with at least a part. of the circular openings 4 60 the hairs entered through the slots 3 in the openings4 may not escape; therefore an excellent shaving effect is obtained. Hairs not entered in the slots may be caught'bythe inner openings 4 separated from the-slots -3 and provided more in "55. the middle of the plate, preferably for the puropenings 4, the; diameter 1 a pose of a secondary flnestshaving. Conforming to the fact, that the outer openings 4 are preferably displaced. with respect to one another two unequal lengths of the cross-slots 3 are obtained. The inner shear-member 2 moved to and fro in relation to'the outer shear-plate I has preferably slots of a width 8 of greater or the same largeness as the width 6 of the bridges of the shearplate I, whereby, conforming to the invention, the cross-slots 3' of the inner shear-member 2 being divided in the middle part by small bridges 9. The bridges 9 are staggered, as shown by Fig. 2, and are so located that in one of the end positions of the inner shear-member 2 they are situated between two openings 4 of the shear-plate I. The openings 4' of the inner shear-member 2, if provided in the same, (see left half of Fig. 2) are situated "preferably in line with the crossbridges separating the cross-slots 3'. During the shaving operation the openings 4 of the 'outer shear-plate I cooperating with cross bridges or' openings of theinner shear-member 2 produce a better result of shaving than by known devices, because the cooperating shear-Openings 4,-4 in the outer and inner shear-plates are reduced by the movement of the inner shear-plate from the full circular form down to a point.

The cross section of the shearing headillustrated by Fig. 4 shows the situation of the longitudinal bridges 9 and the step-like portion I3 for better introducing the hairs in the slots. Fig.

7-shows in modification another form of the steplike portion l3.

In Fig. 5 and Fig. 6 other cross-slots are illustrated. The slots ll of Fig. 5 are situated obliquely to the longitudinal edge of .the shear-plate I. They extend not radially to the circular openings but tangentially. The arrangement described may also be used for crossslots sucheas are shown in Figs. 1 and 3. The arrangem'ent. conforming to 'Fig. 6 shows also obliquely situated slots l2 which are curved.

The invention may be reduced to many other forms not described.

-Havirlg-now described my invention, what I claim is:
