Excerpt: ...which they ought to move $ and as the consequence might be shocks of the leaves or spindles against the sides of the teeth, which would catch these leaves or spindles too soon before the line of centres, mechanists may prevent this inconvenience by making the primitive diame. ter of the wheel a little larger than it ought to be, in regard to that of the lantern or pinion. By By means of this enlargement of the diameter of, the wheel, which ought to be proportioned to the faults that may be apprehended in the teeth, the tooth which follows that which impels the spindle or leaf behind the line of centres, catches a little later the spindle or leaf, which follows; and when the preceding tooth has impelled the spindle or leaf behind the line of centres, as far as it can do uniformly, the wheel acquires a little more velocity than it communicates to the lantern or pinion, which is a defect; but this error into which one voluntarily falls, is lefs to be apprehended than the shocks to which pne would be exposed in attempting to avoid it. It is evident, that what has been said on the enlargement of the diameter of the wheel beyond what is necessary for moving uniformly the lantern or pinion, supposes the lantern or pinion to be driven by the wheel; but when the wheel is moved by a pinion, it is evident, that to avoid shocks it is the primitive diameter of the pinion that must be made a little larger than necessary to move the wheel uniformly. As the teeth of a wheel must impel the spindles of a lantern by removing them from the line of centres, and as no shocks are to be apprehended, in this method of moving a lantern, one may without any inconvenience cause a lantern to be moved by a wheel. But as the spindles of a lantern ought, en the other...
