This crank communicates a verticaloscillating motion to the crank arm 44 ofthe control case. This crank arm is con-nected at its upper end by a connectinglink 57 with the arm 58 which is pivotedon a line with the pivot of the bellcrank44. The pin connecting 57 and 58 car-ries a roller 59, which runs in the slotof the tumbler block 60. This tumblerblock is pivoted on the pin 61, which isfastened in the upper end of the bell-crank arm of the lever 62, which in turnis pivoted at 63. The lower end of thetumbler block carries a roller 64, whichworks in a Scotch yoke 65, which isfastened to the connection 66 leading outto the operating lever of the chutes. The motion of these connections is.
