SPINNING FRAMES. 229 THE DRIVING OF THE SPINNING FRAME. The steadiness of the drive to the Spinning Frame Spindles is ofmuch importance, and it will always be observed that when a pair ofengines are working together driving a mill, the driving will be muchsteadier than when working with a single engine. A 72 SpindleFrame, 4 inch pitch, 4 inch traverse, will require a belt 4 ins. broadand 80 feet long, according to the plan of mill given in this book. Atone time all the belts used in jute mills were made of leather, but thisis not now the case. Many mills work cotton belting. This belt hasmany advantages over leather for driving jute mill machinery ; notonly is it cheaper, but it runs much smoother, owing to the absenceof joints. There is only one joint in the belt. This joint is made veryeasily, and in a much shorter time than you can make a sewed cost of the six copper rivets and washers is trifling comparedwith the price of belt laces.
