The number ofvibrations was obtained by means of a revolution counter,attached to the main gear. In conjunction with this therewas an automatic belt shifter that operated when the boltbroke. When the bolt broke the dynamometer drew the con-nection bar out until it disconnected a dog which allowed agravity belt shifter to throw off the belt. The temperatureswere obtained by means of a bath of cylinder oil and a gasstove. The inside of* the outer sheet, the bolt, and both sidesof the inner sheet, were exposed to boiler temperature, as indie locomotive boiler, while the outer sheet was exposed to theatmosphere on
