Water Elevator Chain.

Patent for a new and improved water-elevator chain. This design "has relation to that class of water-elevators in which the buckets are connected to an endless chain formed of wire, the several links being connected to each other by loops or eyes formed thereon; and the object thereof is to improve the construction of this class of wire chains, whereby the bearings for the links are greatly increased and strengthened and the general construction of the chain rendered more durable, also the links more conveniently coupled together or uncoupled without injury thereto" (lines 17-28)
