From the 17th century onwards people had made many attempts to devise a mechanical log which would automatically record the ships distance done. Edward Massey invented a mechanical log in 1802 with four blades which was used by the Admiralty from 1807-1815. As the rotator was dragged behind the ship then the log rotated and the revolutions were transformed in miles on the dials, to be read after the rotator was brought in. The design of Massey was further refined by Thomas Walker and Son, who took out a patent for the A1 Harpoon Log in 1861.
John Hand & Sons, instrumentmakers in Philadelphia from 1872 made this log as a copy of the Walker’s A2 harpoon log. On the log there are three dials, the first registers the miles up to 100, the second registers the units up to 10 mile, the third registyers quarters of a mile. One of the four rotator blades is stamped with the Hand trademark, a compass card on a hand with JOHN E. HAND & SONS PHILA – BALTO.
The case is made of pine. In it two pages of The New York Times of December 13, 1976.
