Definitions

  • the object of the invention is a shaving mechanism with upper and lower cutter, in which the oscillating upper cutter, with open teeth, is curved in longitudinal direction and bears against the similarly curved stationary cutter.
  • the cutters can be brought into uniform contact with the skin to be shaved.
  • the hairs are well lifted up, thus allowing a quick shaving.
  • Even sharply rounded and hollow parts of the skin can be thoroughly shaved.
  • the upper cutter can be manufactured from an endless band.
  • Fig. 1 is a longitudinal section through the cutting head of the shaving mechanism
  • Fig. 2 is a cross section through the cutting head
  • Fig. 3 is a plan view of the cutting head, with certain parts removed.
  • the lower cutter l with open teeth on its edges is curved in longitudinal direction and fixed to the cutting head 3 by means of the screws 2.
  • a very thin upper cutter 4 likewise with open teeth on both edges.
  • This upper cutter is also curved in longitudinal direction, but has a plane cross section.
  • the ends 5 of the spring stirrup 6, serving as a driving means for the upper cutter 4 engage slots l5 of this latter cutter. Since the ends 5 have the tendency to go away from one another, the upper cutter 4 is constantly stretched by the stirrup 8. On compressing this stirrup, the upper cutter can be removed.
  • a spring 1 bearing on the one end against the cutting head 3, and on the other end against the stirrup 6 provides for the upper cutter 4 being pressed against the lower cutter I.
  • a fork 8 receiving a sleeve Ilia rotatably mounted on the pin I0 fixed to the casting oi'the shaving mechanism, engages the stirrup 8.
  • the sleeve Ilia also passes through one end of and the fork 8 and lever H are secured together on the sleeve between a flange Illb at one end thereof and a nut I00 threaded on the other end.
  • An eccentric I: on a driving shai't l4 engages in a slot I: in the lever ll.
  • Shaft M is driven by a non-illustrated motor. It the eccentric I3 rotates, lever II and fork I oscillate. This latter transmits the oscillating movement to the stirrup 8 and thus to the upper cutter 4. Since the slots is are long enough so that the ends I cannot at any moment bear but against the outer edge of these slots, the upper cutter is drawn, on a righthand movement. by the right-hand end I. on a a lever H:
  • a lower stationary cutter with open teeth curved in longitudinal direction, and an upper oscillating cutter with open teeth, bearing in a corresponding curve against said lower stationary cutter.
