As the latter movesback and forth, it slowly revolves the ratchet wheel D and bymeans of the bevel gear I and J, the transformer shaft K isslowly turned. From the transformer the motion is transmittedto the lubricator by a shaft usually made of iron pipe (used inplace of a solid rod), which, with one universal joint at thetransformer and one other at the lubricator, takes care of the dif-ference in positions of the transformer and the lubricator. Thistransformer may be located on the running board or on a bracket
