Definitions

  • the present invention relates to such shaving or clipping machines as are provided with a grooved comb plate resting against the skin when the machines are used, the said comb plate surrounding a likewise grooved knife plate, which by means of a drive device located in the casing forming the handle of the machine and supporting the comb plate is adapted to be set into reciprocating motion, the clipping taking place by the cooperation of the grooved edges of the plates.
  • the old machines of this kind have not given the desired result as they do not rest sufiiciently tight against the skin although various attempts have been made to obtain a good efiiciency by a special embodiment of the grooved comb plates.
  • the problem has been solved for the first time and, from a point of view of construction, in a very simple way
  • the handle there are mounted one or several fans, vacuum pumps or the like driven by the drive device and adapted to produce, via one or several channels, an air current going through the comb plate and causing the skin to rest against the comb plate.
  • the machine need only be slightly moved over the skin, the skin being sucked to rest well against the comb plate.
  • it is quite unnecessary to press the apparatus hard against the skin as has mostly been done earlier, in order thereby to obtain an increased efficiency, which increased efiiciency, however, has not been forthcoming. Consequently, a good shave is obtained by the present machine without the skin being irritated.
  • Figure 4 is a section on line IV-IV of Figure 1, and
  • Figure 5 shows the clipping members on a larger scale.
  • the handle the casing of which has been given a circular cross section.
  • an electric motor 2 driving a shaft 3.
  • 4 indicates the grooved comb plate connected with the handie, the said comb plate surrounding the likewise grooved knife plate 5, see Figure 5.
  • the knife plate is adapted to be set into reciprocating motion in a wellknown way, hair entering between the grooved edges of the plates 6, 5 being cut off.
  • the grooves 6 of the knife plate 5 communicate with a channel 1, and by means of a fan 8 attached to the shaft 3 there is efiected an air current going through the comb plate and causing the skin to rest against the comb plate.
  • the grooves 6 of the knife plate 5 form such an angle with the grooves l l of the comb plate 4, and have such a width relatively to such grooves that, as is clear from Fig. 2, there is never a complete closure of the cut-outs. In other words, air will continuously pass through the slots of the comb plate and knife plate into the channel I.
  • the cut hair which, of course, follows the air current is to be collected in an annular chamber l3 formed by the outer wall of the handle I and a cylindrical sieve I2 is located at some distance from the said wall.
  • the air current going through the sieve l2, the said air current being sucked into the fan through channels I4 will, thus, before leaving the handle through the hole l5 be freed from cut hair.
  • the handle is provided with openings it, which are adapted to be opened and shut off by means of a turnable ring l8 provided with openings H.
  • the ring I8 is adjustabl in various turning positions by means of a spring-actuated ratchet l 9 adapted to cooperate with holes 2!! in the ring.
  • a shaving machine comprising a motor, a slotted knite plate member operatively connected to said motor and reciprocatable by the latter, a series of cutter blades on said knife plate ad-' jacent respective slots, a slotted stationary comb plate member surrounding the outer end of said knife plate, a series of stationary cutter blades on said comb plate adjacent respective slots, adapted to cooperate with the cutter blades of said reciprocatable knife plate member, the slots in said comb plate registering with the slots in said knife plate to form openings for the reception of hairs to be sheared, the cutter blades and slots of one of said plate members being angularly disposed with respect to the cutter blades and slots of the other of said plate members, whereby the openings are maintained against closure independent of the mutual positions assumed by said plate members during reciprocation of said knife plate, means for creating a suction at said plate members, and perforated strip members along the sides of the comb plate member for preventing skin portions located laterally of the knife plate member from being drawn against the comb plate member.
