Wharf Street Mills, Ashton-under-Lyne

of Ashton-under-Lyne.

1892 'THE NEW ENGINES AT MESSRS. KNOTTS' MILL. .... recently erected by Messrs. Scott and Hodgson, engineers, of Guidebrige, ... it must be remembered that the boiler-house and engine-house are separated from the mill by a street, and that the motor power has to be conducted across by means of a huge shaft. A week before the Wakes the mill was stopped in order that the old engines might be pulled down and the new ones — a set of vertical triple expansion engines — put in their place. The time occupied in putting in the new ones was 21 working days, and during that time part of the old time engines had to be removed and the foundations altered, so as to fit the new ones. And now for the figures and measurements. The as we said are triple expansion and vertical, and are working with a pressure of 200 lbs. The high pressure cylinder is 14 inches diameter, the intermediate 22 1/2 inches, and the low pressure 36 inches. The stroke is 3ft. 6in., and makes 65 revolutions a minute. The cylinders are fitted with Corliss valves, the high pressure having a trip gear regulated automatically by the governor. The crank shaft is constructed on the built-up principle, and is made from Siemens Martin mild steel. The flywheel. which is in two sections, is 16 feet in diameter, and weighs about 15 tons. ...'^[1]
