Definitions

  • the present invention relates to a dry shaving apparatus, including at least one cutting member and at least one abrading member mounted on a body rotating within a sheath provided with openings, comprising means allowing the removal and the positioning of the cutting and abrading members rapidly and without tumbling.
  • the said body is provided with a central part driven by a driving shaft and comprising at its ends cheeks which receive the ends of the above-mentioned members, one of these cheeks being provided with openings within each of which is engaged a lug extending from one of the ends of each of these members, whereas the other cheek comprises radial slots into each of which is engaged a lug provided at the Opposite end of each of these members, a holding member being mounted around at least one part of the said slotted cheek to hold radially these lugs in working position, this holding member having an opening capable of coinciding in succession with the various slots, when it is made to rotate around the cheek which it carries, in order then to allow free passage for the corresponding lug and thus permit, with ease and without fumbling, the positioning and removal of the above-mentioned members.
  • Fig. l is an elevation view of the rotating body included in the apparatus, the sheath surrounding this body being removed.
  • Fig. 2 is a plan view corresponding to Fig. 1.
  • Fig. 3 is a longitudinal sectional View according to III-III of Fig. 2.
  • Fig. 4 is a cross sectional View according to IV-IV of Fig. 3, it being understood that certain members are removed.
  • Fig. 5 shows a detail in elevation.
  • Fig. 6 is a view from below corresponding to Fig. 5.
  • Fig. '7 is an outer view, in elevation, of the head of the apparatus showing the sheath.
  • Fig. 8 is a plan view corresponding to Fig. 7, partially in section.
  • Fig. 9 is a detail View in vertical section.
  • Fig. 10 is a perspective detail view.
  • Fig. 1l is an elevational view on the opposite side to that according to which the apparatus is viewed in Fig. 7
  • the dry shaving apparatus shown in the drawing includes a rotating body formed of a cylindrical portion l and two cheeks 2, 3 fixed to a shaft 4 driven by a motor not shown.
  • the cheek 2 is provided with six openings ll each of which is designed to receive a lug I2 extending from one of the ends of each of the members 8, 9 and ID.
  • the other cheek, 3 has six radial slots I3, into each one of which extends a lug Ill provided at the opposite end of each of the members 8, 9 and I9.
  • a holding member i5, cupshaped, is mounted around one part of the said slotted cheek 3.
  • the cylindrical part of this holding member I5 has a radial slot I6 which, when the member I5 is made to rotate by hand around the cheek 3, may be brought successively in registry with each of the slots i3.
  • the bottom of the cup, formed by the member I5, is interiorly provided with a series of swells Il, spaced at 30 from each other and obtained by embossing themetal of this bottom. These swells, twelve in number, are arranged to co,
  • the abrading members shown in the drawing are each formed by an abrasive stone I0, a part of which is of general cylindrical shape 22'; provided with oblique slots123.
  • the main cutting members 8 are formedof metallic blades whose cutting portion Eli'conprises'a seriesof slanting edges, as shown more clearly in Fig. l.
  • the cutting portion li' moves practically in contact with the inner surface of. the perforated sheath 5.
  • This sheath, in the perforated part applied to the surface to be shaved, is of very small thickness, for example of the order. of 5/100 mm.
  • the cylindrical surface- 22, of the abrading members Ill rotates at a short distance from the inner surface of the sheath 5, but without contacting the same.
  • the auxiliary cutting members 9 are formed as. follows; as in the case of the members 9;,theyl comprise a metallic blade each arranged on the rotating body along a'radial plane with respect tothe axisof this body, but instead of being provided lwith a cutting part all along one of their longer sides, the active-part of the members 9 is composed of two cutting parts 25, 28 merely at right angles to each other (Figs.v 3 and 9) and rotating Within the sheath 5, one opposite one of the ends of its cylindrical part, and the otheropposite the adjacent endY part 2t', planeshaped, of this sheath.
  • the openings are formed by slots 28. These slots are obliquely arranged with respect'to the axis of the rotating body and extend along the common circular edge 2910i the adjacent regions, respectively cylindrical and plane', of this sheath. The reason for such an arrangement is to permit of closeshaving, in places where little room is available, by applying the edge 29 to the region to be. shaved.
  • Fig. l0 there is shown a modiiication of the slots siwhichare radial instead of being oblique;
  • the space remaining between adjacent slots constitutes a kind'of tooth and, as shown inFig. .10, every other :tooth discloses across slot 3D.
  • a dry shaving apparatus including a cylindrical sheath, a body rotating inside the sheath, and at least one cutting and one abrading' member mounted on the body, the sheath having openings there-in before-which the cutting and abrading members pass alternately, the improvement which consists in the body comprising a central portion having a drive shaft extending axially therefrom, and a pair of end cheeks rigidly connected to the central portion, one cheek having holes and the other radial slots therein, the cutting and abrading members having lugs at both ends for engaging respectively in the holes of one cheek and the slots of the other, and a holding member rotatably mounted on the slottedcheek and having an aperture therein registeringin turn'with each of the slots thereby to permitdisengagement of each lug from the enveloping slot as the aperture of the holding member is Ypresented to each slot in turn.
  • eachcutting member comprises a blade located in a radial plane of the body.
  • each abrading member comprises a stone having an. abrading surface arranged to rotate: past the inner surface of .the sheath at the pointy thereof where the openings are provided.
  • At least one cutting member comprises a blade having two cutting edges substantiallyat right angles to one another, oneedge rotating in a.
