THE ANCHOR DRIFTOGRAPH,
Abstract
It was proposed to construct, and introduce into practical anchor station work, a driftograph, based on the principle of making allowance for drift by recording the movements of a heavy pin-studded cylinder over the sea floor. The driftograph has a recording mechanism, which during operations is enclosed in a hermetically sealed thick-walled steel cylinder. The latter is mounted inside a cylindrical watertight housing, fitted with pins to secure better gripping of the bottom. The housing is hollow, and has on its ends the half-axles, turning in the rings of the side-rods when the roller is in motion. Between the siderods, which are joined by the cross-tie bolt, there is mounted a triangular flat hull, made of thin sheet iron. The purpose of this hull is to keep the driftograph from burying itself in the sea-floor when it is being pulled around, and to make it easier for the driftograph to surmount sea-floor obstacles.
