The engagement of the pulley and clutch is determined by a hand-controlled block F sliding on the shaft, the movement of which is communicated to the rightand left-handed screw shafts by links G connected to the levers H.
By the time he caught up with them, Donnie had recovered somewhat, but gone was the enthusiasm demonstrated earlier and he continued to clutch his father, as close as the seat belt would allow.
The clutch mechanism is freed at the proper time by the action of the vertical rod at the end of the beam, and the brushes then he 4-lb weight is being lifted.
The automatic sight consists of a bent lever roller cam m, also secured by the bolt e to the carrier; the lower end of the lever carries the cam roller n, which is constrained to move in the cam p by means of the spring in the spring-box g; the rear end of the horizontal arm of the lever is formed into jaws v; the same action of the clutch t which releases the worm and hand-wheel forces a catch on a vertical stem u into the jaws of the lever, and fixes the rocking and sight bars rigidly to it.

The worm and hand-wheel are thrown into and out of gear by means of the clutch t.
