Definitions

  • This invention relates to dry shavers of the type in which a movable cutting member moves relatively to another member to cut hair by a shearing operation, and more specically to that 5 type of dry shaver in which one of the two relatively movable members is moved in contact with, and directly across, the face in the shaving operation.
  • a stationary face engaging cutting member having turretlike teeth upwardly projecting in opposite directions; the provision of a cutting member having projecting pyramidal teeth, the facing sides of adjoining teeth being inclined to each other to form V-openings; the provision of said V-openings between teeth, the sides of which are inclined to each other; the provision in the face engaging cutting member of a dry shaver, of a shank portion from both sides of which project a plurality of teeth, the top edges of opposed teeth converging on a medial line of the shank, the point of intersection of the top edges of a pair of opposed teeth being spaced (on the said medial line) from the point of intersection of the adjoining teeth; the provision, in the cutting member of a dry shaver, of teeth the sides of which are inwardly converging and downwardly inclined; a new arrangement of the stationary cutting member and the movable cutting member, together with a guard member sheathing the coacting teeth of the said members; an improved contour and shape of guard teeth protecting the face
  • Figure 4 is an exploded isometric view, showing, from top to bottom, the face engaging, stationary cutting member, the movable cutting member, and the base member of the shaving head, the latter comprising as part thereof the guard teeth;
  • Figure 9 is a perspective View on an enlarged scale showing the construction of the teeth of the stationary cutter.
  • the shaving head of my improved dry shaver comprises essentially three parts, namely a base member designated generally by the reference character I0, a movable cutting member designated generally by the reference character 30, and a stationary cutting member desnated generally as 50.
  • the base member I0 is made integral and of generally rectangular shape and is provided with a central longitudinal passage which forms right and left sides, respectively, IIR and IIL (which serve as guards, as will be more fully described).
  • IIR and IIL which serve as guards, as will be more fully described.
  • the movable cutting member 30 Within this longitudinal passage of the base member I is reciprocated the movable cutting member 30, for which purpose the base member is provided with a slideway I2 at the bottom of the central longitudinal passage (best shown in Figure 3).
  • the distal end c is also in the form of a trapezium, as clearly shown in Figure 9.
  • the facing lateral sides between the teeth converge downwardly so as to meet at an imaginary line Z.
  • a concave face engaging member having oppositely projecting and oppositely inclined lateral portions, the top surfaces of which intersect in a medial line and slots running inwardly from the outer edges of said lateral portions so as to form outwardly projecting teeth.
