Figs. 135, 134, 137, 136. Movements of various kinds
[Fig. 136]. This represents an expanding pulley. On turning pinion d to the right or left, a similar motion is imparted to wheel c, by means of curved slots cut therein, which thrust the studs fastened to arms of pulley outward or inward, thus augmenting or diminishing the size of the pulley.
[Fig. 137] represents a chain and chain pulley. The links being in different planes, spaces are left between them for the teeth of the pulley to enter.
[Fig. 138]. Another kind of chain and pulley.
[Fig. 139]. Another variety.
[Fig. 140] shows two different kinds of stops for a lantern-wheel.
