Definitions

  • Figure 1 is a view in partial axial section of the first embodiment
  • Figure 2 is a side view corresponding to Figure 1;
  • Figure 3' is a plan with a semi-section accord-- ing to II-I-III of Figure 1;
  • Figure 4- is apartial view in elevation of the second embodiment
  • FIG. 5 is a similar view to Figure 4, but in partial median section; V
  • Figure 6- is a cross-section on the line VI-VI of Figure 5;
  • Figure 7 is a cross-section on the line VIIVII of Figure 5.
  • the apparatus represented by Figures 1 to 3 includes:
  • the revolving body 5 is in stone of the whetstone type and has a cylindrical revolution shape. On the periphery of the body 5, a channel of is provided, extending parallel to the axis of this body and in which a metallic U-shaped part It is lodged, the median portion H of which forms a grid with parallel slits.
  • the grid H projects beyond the lateral surface of the cylindrical stone 5.
  • the directionof rotation of this stone is indicated 2 v by an arrow in Figure 3. It is seen in the same figure that the front edge of the grid H is situated at a shorter radius than its rear edge.
  • the apparatus represented comprises also a cutting-blade l2 presenting an elbow at I3 and the cutting-endof which is indicated at E4.
  • the blade ii. presents a bent parti 5 which fits into a corresponding slit in the 02.5- ing it for detachably fixing it on this casing, as-is' seen in Figure 3.
  • the part of the blade i2 111- eluded between the end it and the elbow It has a less pronounced curvature than the cylindrical casing 3 ( Figure 3).
  • the free end of the blade 12 passes through the opening 8 to co--operate with the grid l I, as is described farther on.
  • a metallic ring I 5 Around the casing S is placed a metallic ring I 5, slightly flexible, extending over about twothirds of the periphery of this casing. 6
  • This open ring presents, at each end, a bent-back-part ii and N3 respectively allowing it to be turned around the casing- 6 with the fingers, concentrically to the axis of the apparatus, with the ob ject that isindicated below.
  • This stone thenacts asan abrasive which rubs away the part of the bristles that have just been cut and which still projects beyond the surface of the skin. This projecting part of the bristles is thus eliminated, and this is done at the same stage of working as the actual cutting since, in the course of the successive rotations of the revolving body, there is alternately a cutting operation and an abrading one.
  • a sleeve 23 is mounted for sliding on the shaft 2. This sleeve is integral with a propeller 2
  • the sleeve 23 is integral with a coupling member 22 with ratchet teeth, intended to co-operate with a similar element 23 nxed on the shaft 2.
  • a compression spring 24 induces the elements 22 and 23 to stay separate, as is seen in Figure 1. One end of the spring 24 bears against the base I and the other against a disc 25 with a milled edge, as indicated at 26.
  • the disc 25 is intended to move axially with the sleeve 2n without participating in its rotation.
  • Openings 21, 28 cut in the easing 6 allow of taking hold of the disc 25 by its periphery to move it axially. towards the position in which the elements 22 and 23 are engaged. The instant this coupling takes place the propeller revolves and blows out the beard clippings that may be under the grid or inside the casing 6. As soon as the disc 25 is released, the spring 24 brings it back into the position shown in which it is pressed against languets 29 punched in the comprise, not slits, but circular or triangularshaped openings, for example.
  • the apparatus represented in Figures 4 to 7 comprises a; body 3
  • bears a detachable head 32, the cylindrical top 33 of which presents a zone 34 provided with narrow openings 35 formed by a series of small slits and another zone 30' provided with openings 31 larger than the openings 35.
  • a mobile mechanism revolves, driven by a shaft 38 itself driven by the motor enclosed in the body 3
  • the head 32 is fixed on to the body 3
  • the revolving mechanism comprises a part 4
  • This part possesses two radial slots 42, diametrically opposite, as is seen in the drawing.
  • a blade-holder 43 is mounted so as to oscillate; this blade-hoider possesses a hook cooperating with an axis 44.
  • a circular clip 45 placed round It is easily understood that, under the influence of the centrifugal force acting on the bladeholder 43, the clamp 46 and the blade 48, and which is due to the rapid rotation of the shaft 38, each of the cutting-blades 48 is impelled outwards and revolves with its cutting-edge in contact with the inner surface of the casing 33, as is seen on the right-hand side of Figure '1.
  • each of the cutting-blades 48 presents a portion 49 which, when the blade passes in front of the zone 36 with the large openings 31, co-operates with a surface 50 on the inside of the head 32 and this obliges the said blade to recede from these openings towards the axis of rotation.
  • the surface 53 is of a cylindrical shape, but is situated at a shorter distance from the rotation axis than the inner surface, also cylindrical, of the head 32 ( Figure 6).
  • the revolving mechanism comprises also an abrading member consisting of a stone 5
  • revolve in the immediate proximity of the inner surface of the head 33, as is seen in Figures 6 and 7.
  • each of the blades 48 successively passes, for every revolution of the shaft, in front of the zone 34 with the small openings 35 and the zone with the large openings 31.
  • this blade in co-operation with these openings, cuts the hairs of the beard engaged in these openings when the zone 34 is applied against the part of the face that is openings 31.
  • each of the parts 52, 53 of the abrading member successively passes in front of the zones 34 and 350i the head of the apparatus.
  • the abrading member passes in front of the zone 34, it has no effect, whereas, when the parts 52 and 53 of the member 5
  • the dimensions of the openings 31 are, in fact, large enough for the skin to come into contact across them with the abrading member when the zone 33 is applied against the face.
  • either the zone 34 or the zone 36 can be brought, with a very slight movement of the hand, into contact with the surface to be shaved, contact with the zone 34 producing the cutting of the hairs of the beard and contact with the zone 33 the abrasion of what remains of the hairs that have just been cut.
  • zones 34 and 35 are contiguous and that they together extend over an angle of less than The angle within which the pair of zones 34 and 36 is confined may with advantage,
  • a dry shaving apparatus comprising a cutter, means for presenting to the cutter only an extreme portion of each bristle, and abrading means associated with the cutter for abrading the portion of bristle intermediate said extreme portion and the skin of the user.
  • a dry shaving apparatus comprising a cutter including a stationary blade and means for presenting to the blade only an extreme portion of each bristle including at least one revolving grid and abrading means for abrading the portion of the bristle intermediate said extreme portion and the skin of the user including at least one abrading member revolving with said grid.
  • a dry shaving apparatus comprising a stationary blade and a revolving body of a generally cylindrical shape including a grid and at least one abrading member mounted on the lateral surface of said body.
  • said cooperating blade being constituted by a metallic member having on one side thereof a part adapted for detachably connecting to said casing and a cutting edge on the other side thereof adapted to penetrate through said lateral aperture and to cooperate with said grid.
  • said metallic member having an ofiset portion adjacent said cutting edge, the portion of said member intermediate said offset portion and said connecting part having a greater radius of curvature than said casing
  • said apparatus further comprising a resilient annular member surrounding the major segment of said casing and encompassing said cutting blade, said annular member being slidably rotatable around said casing to encompass and apply resilient pressure to selectively greater and lesser areas of said cutting blade intermediate said offset portion and said connecting part, whereby the amount of cooperation between said grid and said cutting edge may be adjusted.
  • a dry shaving apparatus comprising a head, at least one cutting blade and at least one abrading member mounted for rotation inside said head, the lateral wall of said head being provided with a first zone of narrow apertures cooperating with said cutting blade to cut the beard and with a second zone of relatively larger apertures cooperating with said abrading memher, the apertures of said second zone being large enough to enable the skin to come into contact therethrough with the surface of said abrading member.
