Definitions

  • FIG.5 A. BEISMA CUTTING HEAD FOR DRY SHAVER Filed Nov. 23, 1962 FIG.5
  • the invention relates to a cutting head for a shaving apparatus having transverse driving, in which one of the cutting plates provided with teeth on both longitudinal sides is fixed by means of a U-shaped brace connected therewith, the limbs of which are connected on both sides to the housing of the motor, while the movable cutting plate is provided with notches on both ends which embrace limbs of the brace.
  • the fixed cutting plate as such in the form of a brace, as a result of which, however, also a rather heavy and expensive construction is obtained, since difliculties are encountered in fulfilling the various requirements, for the cutting function, the fastening and the guiding of the movable blade.
  • the object of the invention is to provide a cutting head for shaving apparatus which can be manufactured in mass production with comparatively low costs and which can be made available in a light construction, while rigid requirements as regards durability and reliability are satisfied.
  • connection brace connected to the fixed cutting plate is formed by a metal plate provided between the fixed and the movable cutting plates and extending throughout the greater part of the width thereof, the longitudinal edges of which plate constituting guides for the movable cutting plate.
  • each limb of the connecting brace is formed from two resilient pieces of plate extending substantially in parallel with each other, the inner of which pieces forming a lug which is embraced by the corresponding notch of the final edge of the moving blade and the outer of which forms a connecting ing which is provided with a spring catch with the motor housing.
  • the function of the limbs of the brace is distributed for each brace over the two lugs of which the limb consists, while using the spring action thereof, as a result of which a cutting head is obtained which can rigidly be connected and which has easily removable cutting plates.
  • connection lugs fall within recesses inside the side walls of the motor housing and co-operate with parts of the spring catch provided therein.
  • a further embodiment is characterized in that the inner lugs of each brace limb laterally support in a clamping manner fixed surfaces of engagement provided in the motor housing.
  • the function can be given in a simple manner of taking along the moving cutting plate when removing the fixed cutting plate, because the inner lugs and in a laterally widened head which overlaps the edges of the notches provided in the short sides of the movable cutting plates.
  • FIG. 1 is a perspective view of the dismantled component parts
  • FIG. 2 is a longitudinal cross-sectional view taken on the line 11-11 in FIGURE 1 of the mantled cutting head with part of the motor housing;
  • FIGURE 3 is the same cross-section as FIGURE 2 shows the cutting head in an oblique position, a limb of the brace being slid in the housing, and FIG. 3a shows a detail in side elevation;
  • FIGURE 4 is a cross-section taken on the line IV-IV in FIGURE 1 of the mantled cutting head
  • FIGURE 5 is a plan view of the motor housing.
  • FIG. 6 is a cross sectional 'view of the present device with the parts thereof in their assembled condition.
  • FIGURES 1 and 4 the component parts are shown in an upside down position with respect to the position shown in FIGURES 2 and 3.
  • the first pair of legs of the frame 3 which form the actual connection with the motor housing are designated by 8.
  • a driving cone 9 is fixed in the movable blade 1 and the head of the driving journal driven by the motor shaft in a vibrating motion is indicated by 11 in FIG- URES 2 and 3.
  • the fixed cutting plate 4 is provided with two flanged eyelets 12 (see FIGURES 1 and 4), of which in FIG- URES 2 and 3 only the center lines are indicated, which are passed through apertures 13 (FIGURE 1) on either side of the body of the frame 3 and with which this frame is rigidly connected to the plate 4.
  • the second pair of legs 14 are formed which extend in parallel with the connection legs 8 of the limbs 5.
  • the legs are widened on either side, so that a widened head 15 is formed which legs embrace the edges of the slots 7 of the movable blade 1 (FIGURES 1 and 4), as a result of which this is detachably and slidably connected to the frame 3.
  • the legs 14 also form an additional support against vibration in a longitudinal direction of the fixed cutting plate 4 with the movable cutting plate 1, because these resilient legs engage with some pressure transverse ribs 17 provided in the motor housing 16.
  • the movable cutting plate 1 after removing the cutitng head may be removed by sliding the cutting plate to the left or to the right through such a distance that the end edge of the slot 7 abuts against a leg 14. At the one end the cutting plate may then be lifted and guided beyond the widened head 15 of the leg located on that side possibly by forcing it slightly to the exterior in a resilient manner.
  • the blade 1 In order to prevent that when fixing the cutting head to the motor housingwhen by the fixing movement itself the blade 1 has to be brought from such an extreme position into a position in which both legs provide guidancethe blade during its movement to the center would abut with its free end against a leg 14 and consequently could not be brought further into its work position the slots 7, are provided with bevelled corners as indicated by 18.
  • the cone 9 is constructed with a widening such that the driving pin 11 during fixing the cutting head in an oblique position and with the movable blade 7 in the position slid most laterally, all the same engages already therein and, on further pressing the cutting head, is automatically guided into the central aperture 19.
  • a spring catch of the shaving head in the motor housing is obtained by means of the outer legs 8 of the limbs because in the housing 16 (see also FIGURES 3a and 5) on either side a pair of abutment stops 20 are provided which project at right angles to the principal surface of the corresponding leg 8.
  • Each leg 8 ends in a rib 21 projecting on either side beyond the central portion of the leg which rib is obtained by bending that end of the leg concave.
  • legs 14 will also be passed along and in a resilient manner against the side of the ribs 17 because the upper edge thereof is rounded.
  • the shaving head may also be inserted and removed again without objection in an upright position in the direction of the arrow R.
  • a cutting head for a dry shaver having a reciprocating driving means comprising a housing, a fixed cutting plate, a movable cutting plate provided with cutting teeth and notches at opposite ends thereof, a substantially U-shaped frame having a first pair of legs thereof removably connected to said housing, a second pair of legs on said frame insertable in the notches of said cutting plate, said frame being rigidly connected to said fixed cutting plate, the body of said frame being located between said fixed and movable cutting plates, and the longitudinal edges of said fixed plate constituting guides for said movable cutting plate.
  • a cutting head for a dry shaver having a reciprocating driving means compirsing a housing, a fixed cutting plate, a movable cutting plate provided with cutting teeth and notches at opposite ends thereof, a substantially U-shaped frame having a first pair of legs thereof removably connected to said housing, a second pair of legs on said frame insertable in the notches of said cutting plate, said frame being rigidly connected to said fixed cutting plate, the body of said frame being located between said fixed and movable cutting plates, the longitudinal edges of said fixed plate constituting guides for said movable cutting plate, each of said pairs of legs being resilient, struck-up parts of said frame extending substantially parallel to each other.
  • a cutting head for a dry shaver as claimed in claim 2 further comprising recesses and abutment stops in said frame, said outer pair of legs on said U-shaped frame resiliently engaging the abutment stops in said recesses in the housing.
  • a cutting head for a dry shaver having a reciprocating driving means comprising a housing, a fixed cutting plate, a movable cutting plate provided with cutting teeth, and notches at opposite ends therof, a substantially U-shaped frame having a first pair of legs thereof removably connected to said housing, a second pair of legs on said frame insertable in the notches of said cutting plate, said frame being rigidly connected to said fixed cutting plate, the body of said frame being located between said fixed and movable cutting plates, and the longitudinal edges of said fixed plate constituting guides for said movable cutting plate, said frame having recesses therein and abutment stops in said recesses, said first pair of legs each having a rib at the free end thereof projecting inwardly, said ribs being inserted first into said recesses and resiliently engaged with said abutment stops when said cutting head is placed in said housing.
