These Plates are off a MANUALLY operated overhead crane made by the Alfred Box Co. The crane was built into the building in the late 1880's. The building was originally a brick manufacturer or a trolley repair shop, there was a couple of each in that area. Now it is a paper mill. The crane was not electric powered in any way, all funtions were by hand cranks. Alfred Box didn't make an electric crane or hoist until 1921, then his company merged with two others to become Shaw-Box which is still in business today. I rubbed soapstone on the one for clarity. They are pretty beefy cast steel 9" x 38" x 1/2".
