Description:
Abstract:

This invention consists in the employment, in connection with an engine or other governor, and a dash-pot of usual construction, of an intermediate spring connection, uniting the moving parts of the governor to the piston of the dash-pot, by means of which the governor is adapted to move with greater freedom and to be checked with less suddenness under quick changes in the load, than if its parts were rigidly connected.

Claim:

The combination, with a governor and dashpot, of an intermediate spring connection.
