Definitions

  • the dry shaving devices currently available are usually elctrically-powered, consisting of a rotating or oscillatory set of blades acting against a stationary foil, or grid of blades forming a foil, by which a shearing action cuts bristle from the surface of facial or other skin at a close distance from the skin, the bristles protruding up through the foil or grid of blades before being cut.
  • the significant disadvantage of this system is that, because of the thickness of the stationary foil between the set of cutting blades and the skin, the bristle is cut at a slight distance above the surface of the skin, resulting in a shave not as close as that derived from a conventional wet shave, ie. using what has become known as a safety razor, in combination with soap or other bristle-softening measure to assist with cutting.
  • the device described here seeks to combine the virtues of each type of shaving heretofore described, ie. to produce a shave closer than that achieved with current dry methods and of comparable closeness to a wet shave, but with the relative convenience and quickness of a dry shave.
  • This device operates on a similar principle to that of what is known as a cylinder grass mower.
  • the main differences between this device and such a mower are:-
  • this device is designed to cut as close to the surface from which material is being cut, and as far as possible actually at the surface, rather than, in the case of a grass mower for example, leaving a short length of grass behind for visual and perhaps other imperative.
  • this device is operable in two directions, whereby cutting is effected by moving the device either backwards or forwards, and this is effected automatically without the need to make any adjustments.
  • the cutting assembly is serrated from the drive assembly by a system of springing, whereby the cutting assembly is allowed to follow the surface or contours of the skin, broadly independently of the drive wheel assembly.
  • Fig.1 comprises a side elevation and a half-front sectional elevation
  • Fig.2 shows a cylindrical blade assembly in relation to the stationary blade at the surface of the skin, with the alternate position (in dotted outline) of the stationary blade as for the reverse direction of operation.
  • a drive wheel 1 having gear teeth on the inside face of the wheel band 8 into which is permanently engaged a cog wheel 2.
  • Another wheel 20 is located on the far side of a spindle common to this and the cog wheel 2.
  • This smooth, or toothed, wheel 20 drives via a smooth or cogged belt 3, a driven wheel 4, attached to a shaft 5, which slides vertically in slot 9.
  • the belt 3 is elastically-extendable, thus allowing the shaft 5 to move perpendicularly in relation to surface 13 and away from surface 13 when an appropriate force is applied to the shaft 5. This action does not interfere with the action of the belt 3 in driving the shaft.
  • a series of blades is arranged in a circular formation with their cutting edges outermost. This is a typical section through the cutting cylinder, and the blades are arranged by means of fixing pieces 17 to a circumferential support member 18, which is in turn attached to the shaft 5 via spokes 19.
  • the outer, cutting edge of the blades 16 moves across the leading edge of the stationary blade 7 in a shearing action. Because the blades 16 are mounted essentially in a spiral manner, according to the half-front sectional elevation of Fig.l, there is an additional shearing action in a sense longitudinal to the edge of the stationary blade 7.
  • the actual position of this blade in either position 7 or 14 may be varied according to the best position for effecting the closest or most comfortable shaving.
  • the lower portion of Fig.2 shows an alternative style of stationary blade which may allow a closer cut of bristle 21.
  • the stationary blade may be of any shape to produce the closest cut, and in any position. It is arranged to be in direct contact with the skin 13, or surface from which material is desired to be cut.
  • the spiral nature of the arrangement of the blades 16 forming the cutting cylinder means that one blade of the set of blades 16 is always in contact with the stationary blade 7/14.
  • the number of spiral blades 16 forming part of the cutting cylinder may vary according to the desired frequency of cutting.
  • the number and gearing of the drive assembly shown is calculated to provide approximately 1.5 cuts per millimetre of horizontal travel by the blade 7/14, but this may be varied by alternative gearing and/or blade frequency, according to need or requirement.
  • the device is operated by holding the handle 11 and applying the drive wheels 1 to the surface of the skin 13 or other surface from which material is to be cut, and then manually moving, by means of the handle 11, the entire assembly essentially parallel to the surface 13 and at the same time applying a force approximately perpendicular to surface 13, so that surface 13, being resilient and flexible in a soft and malleable manner, is persuaded to make contact with blade 7/14 at its leading, cutting edge.
  • Such action causes wheel 1 to rotate, and also cog wheel 2 which is meshed into it.
  • This drives shaft 5 and wheel 20, via belt 3, thus turning shaft 5 on which is mounted blade cylinder assembly 16, 17, 18 and 19.
  • bristle is carried in a circumferential manner upwards and into a reservoir/box 12 where it is stored until discharged at a convenient time.
  • the handle 11 is attached directly to carrier 10, which carries the entire assembly via shafts 22 and 5.
  • Drive wheel 1 is arranged to rotate about the main axis by either a form of shaft or spindle 23, or a further wheel 24, for location purposes.
  • the action of moving the assembly parallel to and in contact with the surface 13 may then be reversed, so that the assembly moves in the opposite direction.
  • the action of doing this causes blade 7, by friction between the two, to a new position, essentially as at 14, whereby the other face of the double-sided stationary blade becomes its cutting edge.
  • the assembly operates essentially in exactly the same way as in the other direction of pull, in all significant respects.
  • the shearing of the bristle material in this invention is essentially different to the action in other shearing devices of a dry shaving nature; for example -
  • a foil separates the moving blade, or blades, from the surface from which material is to be removed, thus leaving behind an unwanted length of bristle, however short.
  • the drive in the device described here from the drive wheels to the rotating blade cylinder, may be effected on one side only.
  • power drive may be integrated as an accessory.
  • the diameter of the cutting cylinder and the drive wheels may be made the same size, or in sizes more similar than those shown here.
  • the bottom blade may be positioned to be lineable with the bottom, outer edge of the drive wheel, or close to it.

Abstract

Un dispositif de rasage à sec comporte une poignée (11) comprenant une lame inférieure fixe, droite (7) qui vient en contact avec une surface telle que la peau d'où font saillie des poils ou autre matériau analogue à des poils, de sorte que ces lames aient une action de cisaillement sur les poils au niveau de la surface, les coupant et les détachant ainsi de la surface. On effectue ceci en tirant la poignée (11) parallèlement à la surface, la lame (7) et les roulettes (1) touchant la surface, de sorte que les roulettes (1) soient mises en rotation, que la courroie (3) soit entraînée par l'intermédiaire de l'ensemble poulie (2, 20 et 22), et que les lames cylindriques (6) soient mises en rotation sur l'axe (5). L'ensemble est monté sur un support (10) fixé à la poignée (11). On peut effectuer l'action inverse en poussant la poignée dans le sens opposé de sorte que la lame (7) tourne, par friction naturelle avec les lames (6), vers une nouvelle position où elle est actionnée par les lames (6) de la même manière que précédemment, mais dans le sens opposé. Le dispositif est conçu pour être actionné à la main, mais une alimentation telle qu'un moteur électrique peut être installée si nécessaire pour entraîner l'axe (5).
