Hoisting Coal from Canal Boats with Dederick Machines

"An improvement made by Mr. P. K. Dederick, of Albany, N.Y., was a horse-hoisting machine that very materially reduced the labor of the horse in hoisting. Previous to this, the horse walked forward to hoist a full bucket, and was obliged to back to lower the empty bucket into the hold of the vessel. With most horses, this latter was harder work than hoisting the loaded bucket, while the Dederick machine increased the speed of unloading but little, it reduced the labor of the horse about one-half."

Quoted from: "Coal handling machinery", C.W.Hunt Company, 1893.

Crane Locomotives

"At the beginning of the 20th century, all essential transport and machine movement, even in the building trade, was by water or rail. This left its marks on the cranes of the day, and a large number of rail-mounted crane structures were utilized - including the rather strange looking 'crane locomotives'. These were steam locomotives to which a steam crane had been added."
