Artifact Description

The hatch rollers recovered from the Jacksonville "Blue China" wreck site are associated with a heavily degraded composite wood and graphitized iron hatch roller base (19.2 x 18.9cm and Th. 1.8cm and a central aperture 2.9 x 2.9cm). The latter consists of a wooden core with an iron outer sheathing and is characterized by 16 angled sprockets set 2.4-2.6cm apart (center to center distances). Four symmetrically set circular nail holes are positioned 4.5cm inward of the roller edge, each 0.8cm wide and with a central shaft 0.55cm thick.
