(or. 30-44) p lar form employedbeing a matter of choice and 6 Claims.

This invention relates to newand useful improvements in mechanical razors, and relates more particularly to a shaving implement having a plurality of cutting elements which have a true shaving action as distinguished from motor driven razors generally which'provide movable and stationary cutting elements which clip the hairs therebetween. i r r The preferred embodiment of the present in vention comprises a razor having a plurality of forming no part of the present invention. Another object of the invention is the provision of an improved automatic shaver wherein u a plurality of cutters are mounted in a reciprocating blade carriage, only the cutting edges spaced cutting elements which are mounted in substantially blade supper ,Means are provided forrapidly reciprocatingthis blade supporter carriage at right angles to the respective edges ofthe cutting elements. The cutters are formedas flat blades and are rigidly mounted on the movable carriage, as aforesaid, at an angle of {more or less, to the plane of movement of said carriage.

This support or carriage is formed with a plurality of spaced recesses which receive such eut ting elements or blades, the recesses such depth as to permit only the actual cutting edge to project beyond the surface of the mov able support. In other words,.the blades are provided with no guard other than that formed by the edges of the recesses and the cutting is .effected in much the same fashion as it is ;per-. formed by astraight or safety razor, except, of

course, theaction is much more rapid.

It is thus apparent that one of the principal objects of the invention is the provision of an improved mechanical razor wherein there is provided a true cutting action and wherein thehairs 1 are severed cleanly and at their bases. Another object of the invention is to provide' arazor havmg a plurality of cutting elements sopositioned as to effectively prevent the cutting of the skin of the user, the several cutting edges rapidly severing the hairs so that the entire fshaving opparallelrelation to each other on a being of I eration may be performed in'a fraction of" the time normally required for shaving.

Still another object of the invention is the provision of a razor of this general character wherein the several blades may through use, and

. cylindrical portion H tion I 2 at its lower end, which collar portion'is of the blades projecting above the upper surface of the carriage, such upper surface being substantially fiat.

The razor constituting the present invention, though motor actuated, is nevertheless not a dry shaver, since it is primarily adapted to be used after the face has been lathered in the usual fashion.

Aswas earlier pointed out, the present mechanical razor] may be driven by any suitable source of power such as an electricmotor, spring Since the particular type of power employed forms no part of the present invention, no details thereof are illustrated in the drawing. Such prime mover is adapted to be enclosed within a housing H] and the cutter head comprises a substantially provided with a collar porprovided with an angularslot ed to cooperate with apin l4 l3 which is adaptat the upper end of the housing l0, thus providing a conventional bayonet type of fastening means for securing the cutting head uponthe housing. The cylindrical. portion Il may be formed integrally with the collar portion l2 or they. may be made in separate pieces and rigidly secured together. The cylindrical portion H is formed with a central vertical aperture I! which supports a shaft I8 which leads downwardlyinto thecasing l0 and vertical section takenpn adapted to be driven by means of the prime mover not shown) contained within such casing.

At its upper end the shaft I8 is formed with an eccentric cam driver portion l9. At its upper end, the cylindrical portion l I is formed with opposed extension portions 2| and with a diagonally inclined face 22, the opposed edges of which are formed with narrow raised portions 23, shown clearly in Fig. 6, which form bearing surfaces for a movable plate 26 forming the base of a blade support or carriage 25. This plate 26 is substantially rectangular in shape and is engaged at its opposite terminals on its side and upper edges by means of inverted L- shaped guide plates 21 which are secured at opposite sides of extension portions 2| of portion H by means of screws 30. The plate 26 is formed with a diagonally disposed aperture 32 of such width as to permit the cam driver W to pass from side to side during its eccentric movement, all as indicated by the broken lines in Fig. 6. The breadth.- of this aperture, as shown in Fig. 1, is substantially the same as the it will be apparent that as the shaft l8 rotates, the eccentric movement of the driving cam l9 will impart reciprocating movement to the blade carriage 25.

diameter of the cam driver I9, and accordingly 7 Mounted on the upper surface of the plate 26 I 30 is a blade support comprising a pair of spaced, opposed angle portions 36 having apertures therein. Plate 26 is further formed with a plurality of apertures 31 therein, the lower terminals of such apertures being enlarged as shown at 38. Such apertures receive screws 39, the heads 40 of such screws residing in the enlarged portions 38 of apertures 31, all as shown in Fig. 4. The spaced angle portions 36 are connected integrallyat their rear terminals by means of a cross piece 42 which is formed with a diagonally inclined upper surface as shown at 43 which receives one of the blades or cutting elements designated as 44. At their forward terminals the angle portions are connected by a guard portion 45. The upper surfaces of the angle portions are formed with a plurality of spaced, aligned diagonal seats 41 which receive the blades 44. The blades are held in place by means of elongated plates 5 depending terminal portions 5| having threaded apertures 52 therein. The lower surface 53 of each plate is diagonally disposed, thus clamping the main body of the blade between such surface and the surfaces 41 on angle portions 36.

The blade is so positioned as to permit the cutting edge 53 thereof to lie on the same plane as or to project only slightly above the upper surface of the blade carriage, and such cutting edge is thus effectively guarded against cutting the skin of the user. Such upper surface is thus .in contact with the skin during the shaving operation and thus provides a distinct safety factor, particularly since too much pressure against the face retards movement of the carriage. This retarding of movement is more pronounced if asmall self-contained spring motor, instead of an electric motor, is positioned within handle I0. It will be noted that the blade 44 and the plate 50 are formed with recesses M and 50', respectively, along their rear edges in order to permit the lather from the face to pass underneath the blades during the shaving operation.

It will be apparent that many changes and modifications may be made herein without de- 0 having downwardly,

parting from the spirit of the invention as defined by the appended claims. For instance, the blade carriage may be mounted at the upper end of the cutting head by any other suitable means and various blade securing means, other than that illustrated, may be employed. The blades may also be formed with a small aperture through which a pin may pass, thus securing the blades in place. Also, the blade carriage may be so arranged as to move in a plane which is at an angle other than a right angle to the cutting edges of the blades. A further modification may be in the means for imparting reciprocating movement to the carriage such as by a reciprocating arm of the type used in various dry shavers.

The plane on which the blade carriage is mounted relative to' shaft I8 is illustrative only, and it will be appreciated that the blade carriage may lie on any other plane desired.
