American engineer and railroad journal . f a part of theload when another part1 s suddenly removed,such as occurs withmany cylinder hoists,and the height to whichthe load is raised maybe nicely adjusted by achain hoist, which is aconvenience in puttingaxles or other piecesinto lathes. The hoist shown ismanufactured and soldby the Chicago Pneu-matic Tool Co. It is op-erated by a Whitelawreversible air motor,and without the chainit weighs 40 pounds,and this size will lift800 pounds. It is madein two sizes, the largerone having aboutdouble the capacity ofthe one illustrated. The motor is intended to work at a pressureof about SO pounds per square inch, and the size illustrated con-sumes only 10 cubic feet of free air per minute. The motor maybe reversed at any time, giving complete control of the throttle is governed by the bar attached to the rear of themotor, and ropes hanging from holes in the bar are fitted withhandles for operating the hoist. The ingenious construction ofthe hoist is clearly seen in the Pneumatic Chain Pneumatic Tool Co. THE AIR-BRAKE SITUATION.

By the pur-chase oi the Boyden inventions, which the Supreme Court saidwere highly meritorious, the Westinghouse company still claimto control the situation, although this is contested in the United States courts by the New Tork Air-Brake Company. The West-inghouse company have been successful in compelling the NewYork Company to cease making t
