The pneumatic chain hoist, which is shownin Fig. 1, consists of a Dake reversing air motor directly con-nected to an ordinary chain block of a standard make. Twopendant hand chains control the motor valve, to which is alsoattached a lever to operate the valve stem on the oil cup, giv-. NEW 400-TOX wheel press, with special elevating tool works COMPANY.

Gor-don, formerly master mechanic of the Juniata shops of thePennsylvania Railroad, the special purpose of the design beingto avoid the necessity of using cranes to place the wheels andaxles in position. The machine is driven by a General Electric constant-speed,multipolar motor which is mounted upon a neat bracket at therear of the hydraulic cylinder. The motor drives the pumpsthrough a gear reduction, and also there is a bevel gear driveand clutch arrangement by which it may operate the elevatingmechanism. The elevating mechanism consists of an elevatingscrew at each end, both of which are operated together by aworm on the long interconnecting shaft below the bed. Themachine is guided in elevating b
