| View Cart ⇗ | Info
“The capstan is a familiar example of this form of wheel and axle. It is used by sailors for warping vessels up to a dock, raising anchors, &c.; and consists of a massive piece of timber, round which a rope passes. This is surmounted by a circular head, perforated with holes, into which, when the instrument is to be used, strong bars, called handspikes, are inserted.” —Quackenbos 1859
