The mechanical governor, which is the emergency gov-ernor, is set to operate a butterfly valve when the speed reaches , or 50 revolutions above normal, when the governor trips aweight which closes the butterfly valve. This emergency valve canalso be operated by hand. The electric governor is the one usedfor the ordinary governing. The governor shaft of the electric gov-ernor is run by a 3-in. leather belt from the turbine shaft. The gov-ernor shaft runs about 200 and is equipped with the regularfly-ball governor. When the shaft is above normal speed, the sleeveof the fly-ball governor makes an electrical contact. When it isbelow speed, another electrical contact is made. Supposing thatthe turbine is above normal speed and the high-speed contact ismade, a circuit is established through a magnetic clutch which con-. FiG. 3.—Genek.\l Pl the plant adjoining the old plant was built. This is 40 .x 80 ft., withA 9-ft. basement. The interior finish of this building is as follows:Maple hardwood floor, wainscotted with dark green terra vitra tile,and the rest of the side wall is finished with terra cotta pressedbrick. All the machinery and iron work is painted deep blue greenwith vermilion and wlaite trimmings. The machinery in the oldbuilding is also painted in the same manner. This addition is shownin the foreground in the general view of the plant. Fig. 2, and its posi-tion is shown on the plan. Fig. 3. In adding to the plant, an ingenious plan has been worked outwliereby the new turbo-generator outfit may operate both the old nects the governor shaft with the port valves, and which runs thegovernor valves down so as to close some of the row of ports. Whenthe speed is below normal, the low-speed contact on the governoroperates another magnetic clutch, which causes the governor sh
