Description: |
Claim:
Our invention relates to that class of steam-governors in which centrifugal force in revolving counterbalanced weights connected by suitable means with the main or valve governing eccentric is utilized, so that variations in the speed of rotation of the flywheel and of the shaft upon which it is mounted automatically varies the supply of steam to the cylinder, whereby uniformity of operation in the engine is secured, and it is adapted to meet the requirements of variations in its load or work. Heretofore said weights, one or more, have been pivotally secured -to the wheel, so as to be capable of swinging freely as pendulous weights, and suitable connecting-links have been secured between the weight and its pivot to its supporting-arm, and to suitable means for causing the main eccentric to be moved laterally in its relation to the shaft, so that as the weights swing outwardly by centrifugal force the eccentric, through the medium of the usual connecting-rod, partially shuts off the supply of steam, whereby the engine is slowed down. In practice such constructions are lacking in sensitiveness and serviceability by reason of the number of parts employed, the friction existing between them, especially between the weight-supporting arm and its pivot, and the necessity of using counterbalancing-springs of very high tension on account of the excessive strain upon them when the speed of rotation is high. |
