Definitions

  • Fig. l is a section of the first example, through the axis of rotation of the knives.
  • Fig.2 is a top view to Fig. 1,
  • Fig. 3 is an elevation of the second example, partly in section, and
  • Fig. 4 is a section along line IV-IV in Fig. 3.
  • the head of the razor is formed by a comb under which several kn'ves with rows of blades arranged on concentric plates, rotate. Each of these rows makes contact with an individual zone of the comb of the razor, the different zones being axial to one another.
  • Fig. 1 the rotatable knives are driven by a non-represented motor.
  • a bearing support 2 is screwed, supporting a threaded coupling rod 3.
  • This rod at the one end, carries a nut 4 with a projection 5, and, at the other end, a projection B entering a groove I provided on the bottom of the drive carrying the knives.
  • the rod 3 rotates in a ball bearing 8 mounted on the'support 2-.
  • the projection of the nut 4 enters a groove 9 of a coupling sleeve l0 taken along by the axle 23 of the non-illustrated motor.
  • the device carrying the knives at the bottom of which the groove T is provided, is held coaxially to the coupling rod 3 by a shouldered screw II, and is composed of a sleeve I2 ending in a plate I3 on which eight blades I4 and two pins I5 are arranged, these pins I5 driving a plate I6 of smaller diameter, lying above plate I3 and having four blades II.
  • the plates I3 and I6 are permanently under the effect of individual springs I8 and I9 respectively, tending to press the blades It and ll against the comb
  • the diflerent knives are thus axially yieldable indee pendent of one another.
  • the comb is round and fixed to a sleeve ZI by means of a ring 22. This sleeve and this ring form together with the comb a protective cap inside of which the hairs out off are collected.
  • a cover 24 prevents the hairs from penetrating into the motor.
  • the handle I likewise contains a non-represented mo,- tor; Its axle 32 is supported on ball bearings33 and is prolonged by a long screw 34 fixed to the end of the axle. On a square part of the screw 34 a drive member in the form of a cap 25 isheld, the edges of which cover the bearings.
  • This drive members 25 carries tongues 26 leaving channels 21 between them the purpose of which is described later on.
  • the sleeves 28 forming part of the rotatable knives 29, the blades of which cooperating with the comb I00 for cutting off the hairs, ride on the member 25. 4
  • the sleeves 28 are coaxial and fitted into one another with a certain play allowing them to slide with regard to one another.
  • Helical springs III lie between these sleeves and penetrate into; the channels 21 of the member 25. The different knives are thus coaxially yieldable independen of one another.
  • the head of the screw 34 serves as safety means on disassembling, for upon removal of the comb, the screw 34 will abut the flange portion of the sleeve 28 of the inner knife 29 and the remaining knives 25 will be retained in position by abutting this'inner knife and each other in turn.
  • a body comprising a head-portion having a comb plate forming the outer'end face of said head portion, said comb plate com ⁇ blades engaging one of said raceways, and spr n each supported on said drive means and on one of said cutters to yieldably press the blades of said cutters into said annular raceways.
  • a body comprising a head portion having a comb plate forming the outer end face of said head portion, said comb plate comprising a plurality of slit annular raceways coaxial to and surrounding one another, a drive means mounted on said body, a cutter for each raceway coupled with said drive means to be rotated around an axis coinciding with the common axis of said annular raceways, said cutters being mounted so as to be axially yieldable independent of one another, each cutter having a plate substantially perpendicular to the common axis of said annular raceways, and blades engaging one of said raceways and being fixed to and projecting axially from said plate, the plates of adjacent cutters being at an axial distance from one another, and springs each supported on said drive means and on one of said cutters to yieldably press the blades of said cutters into said annular raceways.
  • a body comprising a head portion having a comb plate forming the outer end face of said head portion, said comb plate comprising a plurality of slit annular raceways coaxial to and surroundin one another, a drive means mounted on said body, a cutter for each raceway coupled with said drive means to be rotated around an axis coinciding with the common axis of said annular raceways, said cutters being mounted so as to be axially yieldable independent of one another, each cutter having a plate substantially perpendicular to the common axis of said annular raceways, and blades engaging one of said raceways and being fixed to and projecting axially from said plate, the plates of adjacent cutters bein at an axial distance from one another, springs each supported on said drive means and on one of said cutters to yieldably press the blades of said cutters into said annular raceways, and a stop on said drive means to limit axial displacement of said plates caused by said springs on said comb plate being removed.
  • a body a cylindrical head piece fixed to said body, a ring fastened to said head piece, a comb plate arranged at the outer end face of said head piece and fixed to the latter by means of said ring, said comb plate comprising a plurality of slit annular raceways coaxial to and surrounding one another, a drive means mounted on said body, a cutter for each raceway coupled with said drive means to be rotated around an axis coinciding with the common axis of said annular raceways, said cutters being mounted so as to be axially yieldable independent of one another, each cutter having blades engaging one of said raceways, and springs each supported on said drive means and on one of said cutters to yieldably press the blades of said cutters into said annular raceways.
  • a body comprising a head portion having a comb plate forming the outer end face of said head portion, said comb plate comprising a plurality of slit annular raceways coaxial to and surrounding one another, a cutter for each raceway, mounted so as to be axially yieldable independent of one another, a drive means in engagement with one of said cutters and mounted on said body to be rotated around an axis coinciding with the common axis of said annular raceways, a means connecting the cutter engaging said drive means with the adjacent cutter to rotate the latter, each cutter having blades engaging one of said raceways, and springs each supported on said drive means and on one of said cutters to yieldably press the blades of the cutters into said annular raceways.
