<p>A dry shaving device with a handle (11) comprises a straight, stationary bottom blade (7), which touches a surface such as skin from which bristle or other hair-like material protrudes, so that these blades have a shearing action on the bristles, thus severing them from the surface, at the surface. This is effected by the action of pulling handle (11) parallel to the surface with blade (7) and wheels (1) touching the surface, causing wheels (1) to rotate and drive belt (3) via pulley assembly (2, 20 and 22), thus turning cylindrical blades (6) on shaft (5). The assembly is mounted on carrier (10) attached to handle (11). This action may be reversed by pushing the handle in the opposing direction so that blade (7) is rotated, by natural friction between blade (7) and blades (6), to a new position where it is acted upon by blades (6) in the same manner as before but in the opposite direction. The device is designed to be hand-operated, but power such as an electrical motor could be applied as necessary, to drive shaft (5).</p> |
