Description
A ship-log records the distance traveled through the water. With the time in hours between the observations, it gives the ship’s speed in knots.
This is a very nice set with clock, line, rotator, sinker weight, tin with oil and shoe in a pine case with labels and instructions for use in the lid. The log is fixed on a shoe at the stern of a ship. The recorder would have been connected with a line to the rotor at the end of the line. The governor wheel is fitted in an open end housing. The enamel face with two dials.
Thomas F. Walker (1837–1921) patented a log in 1878, the Walker’s patent taffrail ship-log. It was one of the first logs in which the recorder was placed on board the ship rather than being part of the rotator.
