| + Control the Fan by clutch, when the Fan only is driven by the belt. I have designed a pulley for the Crankshaft, this of course controls the following pulley, + so when out of action the belt is Stationary as well as the Fan. From the foregoing brief description I trust you will see the object of the idea. Thanking you, Yours, Faithfully Thomas. T. Edition | ||
