10 Inch Single Block
Description
10 inch single or common block. Dark brown pulley with rope around it. Inner pulley no longer works.
A 10" single block with the rope running through its sheave. A sheave is the piece of metal through which the rope passes. Blocks could be used on board ship to move a rope in one direction, or to increase the mechanical pulling power of a rope. A ship of the line, such as Invincible, would have had over 1,000 blocks of various designs to operate her running rigging alone.
