A speedometer. (Generic title notwithstanding this invention is intended for use by airplanes at sea; one might guess at a naval affiliation of the inventor.) This system uses two telescopes at an angle; the operator measures the time it takes for an object to pass between one sight and the next. Stanworth provides a table of times and altitudes from which horizontal velocity could be roughly calculated.
- Inventor location: Norfolk, Virginia
[Attorney looks like Munn & Co. but is a little harder to decipher than other instances of the same signature.]
