The latter is accomplished by a novel mechanism for converting the rotary motion of the motor shaft into a generally transverse reciprocating motion. The mechanism employs a follower having a guide slot with parallel side faces and conically extending, radial outer contoured surfaces. The follower comprises a bore for the motor shaft or for a cam on the motor shaft and is slidingly mounted thereon. | |
