To all whom it may concern.

Be it known that I, HEINRICH WEsTEN- DORP, a subject of the King of Saxony, and residing at Chemnitz, in the Kingdom of Saxony and German Empire, have invented certain new and useful Improvements in or Relating to Shaving Apparatus, of which the following is a specification.

My invention relates to a shaving device and particularly to a device designed to cut off the hair by means of a shearing action. In the hitherto usual methods of shaving it is necessary to lather the skin which is always a very inconvenient process necessitating auxiliary apparatus.

The object of my invention is to dispense with lathering and to provide a device which acts like scissors to cut the hair closely to the surface of the skin. The new device comprises two blades moved in opposite directions after the manner of hair cutting apparatus. Owing to the particular shape and arrangement of the blades the hair is cut immediately over or on the surface of the skin, which is impossible inthe usual hair clippers owing to the linger-like shape and arrangement of the cutters between which the hair is cut, andthe lessso as the cutters of hair clippers must have a certain thickness depending on the length of the hair being cut. For this reason ordinary hair clippers cannot be used for shaving purposes.

The device according to my invention operates in the following manner: The hair is caught by comblike blades mounted closely to one another on the periphery of a circular rotatable cutter and at an acute angle to the direction of its rotation, and is guided with a stationary cutter against which the obof the circular cut-` ter cooperate in the manner of scissor-blades.

The cutting edge of the stationary cutteris formed with very ine.notches or teeth which prevent sli ping of the hair on the cutting edge so t at the hair must be cut thereon, and as the cutting edge of the cutter is extremely thin, the hair will be cut closely to the surface of the skin. Owing to the close comb-like formation of the oblique teeth which are blades of the circular cutter, the formation of folds of the skin between the oblique blades and 'the cutting edge of the stationary cutter is avoided, whereby injury to the skin is impossible. The device when guided against the hair will always grip the hair and cut it, but will never hurt the skin.

My invention is shown in the accompanying drawing wherein` Figuresl and 2 are an elevation, partly in section, and an end-view respectively of my new shaving device, in which the comblike blades grip the hair on the inner periphery of and cut it off in the outward direction against a stationary annular cutter, Figs. 3 and 4 are corresponding views of a modification in which the hair is gripped on the outer periphery of and cut against the circular cutting edge of a stationary disk cutter, the operation of the device being the same in both cases. Figs. 5 to 8 illustrate a detail of various modifications of the cutting edges of the two'cutters, whereas Fig. 9 illustrates the rotatable cutter in perspective and a broken-off portion of the disk cutter shown in Figs. 3 and 4.

a is the rotating comb-like circular cutter provided with a great number of oblique blades. The sides of the blades may be curved, as illustrated, or straight.

b is the stationary cutter the cutting edge of which is formed with very line notches or too small to be shown in the drawing. The cutter b is connected with a sleeve c which serves as the handle and also as a bearing for the revolving shaft al, carrying the cutter a. The circular cutter a is rotated by means of the crank handle e and caused to bear on the cutter 6 by means of a spring f or any other resilient means. The shaft d instead of being rotated by hand may be rotated by means of mechanical or electric devices of any kind. The coperating cutting edges of the cutters a and b may be located in a plane at right angles to the longitudinal axis of the shaft, as shown in Figs. 5 and 7 or inclined thereto,l as shown in Figs. 6 and 8.
