Abstract

182,022. Hobbies, Ltd., and Jewson, K. S. Aug. 10, 1921. Treadle mechanism. -In treadle - driven mechanism for lathes. drills, circular saws, &c. of the type comprising a reciprocating flexible band D connected at one end to the treadle B and. passing around a guide pulley H and a driving- pulley E, the return spring F for the band D is connected at G to a fixed part of the frame, and the treadle B is provided with a separate return spring C also connected to a fixed part of the frame. The driving-pulley E is connected to the shaft J through a ratchet &c. clutch.
