PATENT LOG Meaning and Definition

1. A patent log refers to a tool used in maritime navigation. Specifically, it is a type of logbook or device that measures the speed and distance traveled by a ship through water. The term "patent log" is derived from the word "patent," which in this context refers to a system or apparatus that has been officially authorized or granted a patent for its design and functionality.

   The patent log consists of a rotatable rotor or impeller, often shaped like a small propeller, which is connected to a line or cable. This line is then deployed over the stern of the ship into the water, allowing the rotor to spin freely as the ship moves forward. The rotation of the rotor is directly proportional to the speed of the ship, and this information is recorded on a dial or counter mounted on the ship's bridge or navigation station.

   By observing and recording the revolutions of the patent log, navigators can determine the speed at which the ship is moving through the water. This information is vital for various navigational calculations, including estimating arrival times, planning routes, and maintaining accurate charting and position fixing.

   Overall, the patent log serves as a reliable and essential device for measuring a ship's speed, enhancing the accuracy and safety of maritime navigation.

Etymology of PATENT LOG

The word "patent log" has its roots in the 16th century, where the term "patent" referred to an official document or license. The word "log" comes from the Old Norse word "lag", which means "a record of a ship's progress".

In the context of navigation, a "patent log" originally referred to a device used to measure a ship's speed and distance traveled through the water. These logs were considered official and granted by a patent, hence the term "patent log". Over time, "patent log" started to be used more broadly to refer to any ship's log or record-keeping device used to measure and record a ship's performance.
