notes: label: Description
content: This pipe wrench was patented by Amos Call, a hardware manufacturer, in 1866. Like other wrenches, this wrench grasped and forced around pipes and other similar items through a back-and-forth motion. Call titled this model the “Improved Pipe-Wrench” as it included a spring within the neck of the wrench that was said to keep the jaw of the wrench tight the pipe as the wrench turned, allowing the jaw to more easily adapt itself to various sizes of piping. This object displays the new innovations in industrial tools and manufactures emerging during this period as industrial labor became more widespread.
