of the change gear 26 is accomplished by mounting the change gear 26 on a thread 3b as the change gear 26 is rotated clockwise relative to the pinion shaft as viewed from the right it will advance to the left as shown in fig3 thereby providing the compressive force on the brake ring 21 conversely rotation of the change gear in the counterclockwise direction relative to the pinion 3 will unclamp or release the brake in the normal windup operation the ratcheting action of the hand lever drives the change gear 26 in the clockwise direction and thereafter the pinion through the brake clamping function previously described this results in lifting the load on the hoist chain 35 it should also be understood at this point that the suspended load will in turn tend to drive the pinion shaft 3 in a counterclockwise direction thereby also applying a braking compression force on the brake ring 21 since the ratchet gear 19 is prevented from rotating in the counterclockwise direction when it is clamped by the brake it also prevents rotation of the hub 14 and thence the pinion shaft 3 the small restraining force produced by the change pawl 25 is sufficient to retain the braking action produced by the change gear 26 thus the load cannot be lowered until the change gear.
