Definitions

  • the invention provides another and better solution by securing the supporting body for the central support to the sidewall of the apparatus and to provide it with one or more apertures in which rotatable driving means such, for example, as cogwheels, balls, discs, rollers, etc. are provided which transfer the motion of the shaft of the driving mechanism to the movable part, in the present case the cutting plate and/or the cutting member.
  • rotatable driving means such, for example, as cogwheels, balls, discs, rollers, etc. are provided which transfer the motion of the shaft of the driving mechanism to the movable part, in the present case the cutting plate and/or the cutting member.
  • the side-wall of the apparatus fis meant here the side-wall of the cutting head or of the frame shaft, which generally serves to or the casing of the dry-shaving apparatus wherein the cutting head according to the invention is utilized.
  • Fig. 1 is a cross-sectional view in elevation of dry shaving apparatus according to my invention.
  • Fig. 2 is a cross-sectional view in elevation of a modification of the apparatus shown by means of Fig. 1.
  • Fig. 1 represents the cutting head of a dryshaving apparatus, which head consists of a cutting plate I provided with radial slits and of a rotatable cutting member 2.
  • the cutting plate On the underside at a central depression 3 the cutting plate is supported and secured by a supporting body 4.
  • the supporting body t is connected, through the intermediary of a flange 5, to the side-wall of the apparatus and more it exhibits apertures 6 in which are provided balls 1 which transfer the motion of the shaft 8 of the driving mechanism to the rotatable cutting member 2, and this through the intermediary of a cylindrical part 9 which is provided with two legs 10 which penetrate into holes provided in the cutting member 2.
  • the drive is preferably effected exclusively by friction. Since the actuation of the balls 1 takes place from the shaft 8 by means of a bowl-shaped member ll whose diameter corresponds to that of the actuated portion of the cylindrical body 9, I obtain here a transmission ratio of 1:1.
  • the cutting member 2 is pressed by means of a spring 12 against the running surface of the cutting plate I.
  • the other end of the spring l2 bears upon a flange I3 of the member 9.
  • the cutting plate is secured to the casing by means of a nut I4.
  • the cutting member 2 is centred at [5 on the central supporting body 4, which results, as has been stated, in that the cutting member runs more quietly.
  • the cutting member may also be centred indirectly on the supporting body if it runs on a cylindrical depression of the central portion of the cutting plate, which depression surrounds the supporting body.
  • FIG. 2 Another form of construction is represented in Fig. 2 wherein similar components are denoted by the same reference numerals.
  • the supporting body 4 forms a hollow cylinder which is coaxially arranged with respect to the driving shaft 8 so that the balls 1 are actuated from the inside and the cutting member is actuated, through the intermediary of the cylindrical body 9, on the outside of the cylinder. in a reduction of the number of revolutions of the shaft 8 so that use may be made of a motor which runs at a comparatively high speed, which is beneficial to the dimensions Besides, in contrast with the construction according to Fig.
  • the pressure between the balls 1 and the running surface of the cylindrical body 9 is not directed exactly axially but substantially radially so that these forces can be taken up by the body 9 itself. Furthermore, axial vibrations of the driving shaft are only transferred to the body '9 to a highly decreased extent so that also the axial displacements between the legs l and the side-"walls of the corresponding apertures in the cutting member are slight, owing to which a more regular functioning; of the cutting member is ensured.
  • the special pressure means mentioned in the descriptionof Fig. 1 may be dispensed with on account of the force increasing effect of the cone lfiprovided on the shaft 8.
