Description

This model was submitted to the U.S. Patent Office with the application for the patent issued to Joseph W. Fowle, of Boston, Massachusetts, August 14, 1877, no. 194037.

The model represents a 1-cylinder, vertical marine engine connected to a propeller shaft and propeller in the ordinary manner, with a float or inertia device for closing the throttle valve of the engine each time the vessel in which the engine is installed pitches sufficiently to raise the propeller out of the water.

The gear consists of a heavy weight suspended in suitable guides and stops near the keel of the ship. This weight is not rigidly fixed relative to the ship but tends to float in position as the vessel rises and falls. The change in relative positions actuates a valve lever on an auxiliary steam cylinder and piston, which, in turn, moves the main throttle valve of the engine.
