Thus the new loopremained on the shank of theneedle, and the same cycle ofmovement was repeated. The old, straight handframes of William Lees systemwere built with a seat whichwas conveniently placed sothat the operator might havefree use of both feet as well asboth hands, such frames re-quiring all four to operate. The seat was a part of the framework ofof the machine. When the rotary shafts were applied, the seat part ofthe framework was done away with. The rotary crank-shaft was con-nected by means of wheels or belts with the main shaft, on which were Fig. 176. Barbs Pressed: SinkerLanding Old Loop on Barbs. oy loop. Fig. 177.
