<p>A blade assembly (16) for electric hair clippers includes a stationary blade (34) having a plurality of teeth (68) arranged in a row, and a reciprocating blade (36) having a plurality of teeth (82) which complement the stationary blade teeth. A cam eccentric (28) which is turned by a shaft (30) attached to a motor moves the reciprocating blade in a back-and-forth motion through a set operating stroke (A), determined by the lateral distance the cam moves during its rotation. A guide bar (96) maintains the reciprocating blade in a blade guide (48) parallel to the stationary blade throughout the operating stroke, but not through the maximum stroke (B) the blade can travel when the blade assembly is removed from a handle (12) for cleaning or other servicing. Anti-lock ribs (56) or an anti-lock bar (156) are provided on the blade guides to engage the guide bar throughout the maximum stroke distance, thereby maintaining the reciprocating blade parallel to the stationary blade throughout the maximum stroke distance. The blade assembly is removably secured to the handle of the clipper by snaps or the like without the use of screws. <IMAGE></p> |
