HiiUr Pneumatic Hoist. The hoisting device shown in our engraving isbeing used with great success over lathes, planers,wheel-boring mills, etc., for quickly lifting andlowering This device has an improved operating valvethat makes ils aciion positive, and ils speeil entirelyin Ihe hands of operator. These hoists are preferably handled with com-pressed air, but any fluid present may be used. Their usefulness is not limited to lifting, butthey are worth half a dozen hands in helpingmove machinery or other heavy objecU, and can heused in any position. Their advantage over chain hoists is their speed,no manual labor required, und the additionalamount of work a tool can do when quicklyserved. The sizes and capacities arc as follows (eightypounds of air being used): S diameter 450 lbs. 6 diameter lbs. 4 ■• 800 ■• 8 ■■ These handy little lifiers are made by the well-known tool makers, Pedriek & Aycr, ^ What men can save in oil and fuel is shown inthe improvements made when oil oil aroad by contract.
