Machine for Wrapping Wire-Rope, Patent Model

Active selection in cart:
This patent model was included with John A Roebling’s “Method of and Machine for Manufacturing Wire Ropes” patent that received patent number 2,720 on July 16, 1842. Roebling’s patent detailed how to manufacture wire rope; this model functioned to wrap greased insulating wire around the wire rope. Wire rope’s strength and durability made it a superior choice to hemp rope in many industrial applications, but its applications went far beyond replacing rope. Date: 1840s. Record ID: nmah_1403809.
