Every pulley a split pulley, 70 per cent, lighter than cast iron and 50 per cent, lighter than wrought iron or Steel. Strong enough for any power required. Made in any size from nine inches to sixteen feet As a material for pulleys wood is better than iron from the fact that it holds a belt much better. Most good mechanics are aware of this fact, but it may not be generally known how great is the difference, and for 'he benefit of our readers we give the result of tw ) tests made and published by two ol the most eminent mechanical authorities :â A â Rehvalue of leather belt Rei. value of leather belt pq c v â 0 t. 01 "_i â c j? d ⢠c 0 .20 â¢30 .40 â 50 .60 4-38 . â 70 >3-43.
