In this position, electrical energy from the battery 8 is directed to the mot-or lltl.
  • Energization of the motor 10 causes rotation of the shaft 12 and thereby rotation of the eccentrically mounted or unbalanced weight M.
  • the eccentricity of the weight mounting i.e., the displacement of the center of gravity of the weight from the axis of rotation of the weight, and the disposition of the weight proximate to the head portion 2 induces vibration of the head portion 2 and therefore the blade 4. Such vibration imparts a slicing motion to the blade 4 whereby to facilitate ease of cutting.
  • vibration in describing the movement of the head the term vibration is intended in a broad or general sense, including a rapid movement in various directions, as for example a gyratory motion or other such motions which may not be included in some technical or restrictive interpretations of the term vibration.
  • the tab 38 is switched to a second position in which the contact 36a engages the eyelet 22 only.
  • Such arrangement interrupts the circuit of the motor 10, but inasmuch as the contact 36b continues engagement with the eyelet 20, operates to maintain a circuit interconnecting the secondary coil 34 and the battery 8.
  • the switch 18, and thereby the secondary coil 34 is then placed in the magnetic field of the primary coil 40 whereby to charge the battery 8.
  • the razor of the present invention is provided with means for adjusting the position of the razor blade 4 in the head portion 2 of the razor.

  • a retainer ring 66 is slidably disposed in an annular groove 68 in the spindle 58 and is urged into engagement with an inwardly directed shoulder portion 70 (FIG. 1) of the nut 64 by a coil spring 72 disposed about tee spindle 58 and between the ring 66 and a flange 74 disposed on one end of the spindle.
  • a guard member sleeve 78 Fixed to the spindle 58 is an externally threaded sleeve 76 and fixed to the interior of the sleeve 76 is a guard member sleeve 78 supporting at its free end a razor guard member 80 (FIG. 2). Received by the neck member 50 and threadedly engaged with the externally threaded sleeve 76 is a rotatable internally threaded sleeve 82. As shown in FIGS. 1 and 3, the sleeve 82 is provided with a pair of lugs 84 to facilitate manual rotation thereof.
  • the guard member 80 has slots 86 therein which receive spaced upright arm portions 88 of a platform 90.
  • the rotatable sleeve 82 abuts at one end the platform 90 and upon rotation of the sleeve 82 causes movement of the platform, as will be fully described herein below.
  • the platform 90 is provided with end members 92 which receive the guard member 80 therebetween.
  • a rod 94 (FIGS. 2 and 3) is received by the guard member sleeve 78, the externally threaded sleeve 76, the nut 64 and the spindle 58.
  • the rod 94 includes a portion of reduced diameter 96 (FIGS. 1 and 3) which receives the threaded insert 62.
