A toolespecially designed for rivet cutting is now being made by Motor Head Face Lathe Fitted With Alternating Current Motor the controller or switch and the rests are mounted on the floorcolumn, making the machine especially adaptable as a port-able tool. All electric parts are totally enclosed and dust-proof. The equipment of the machine includes a 16-in. toolrest with an offset holder, one right-angle rest, one 6-in. andone 12-in. face plate and one 2]4-in. screw chuck. The machine is fitted with either an alternating currentor direct current motor, the illustration showing the rearview of the alternating current machine with the speed con-troller attached to the head. The alternating current motorhead will run at SOO to .\500 r. p. m., the speed being con-. pneumatic Rivet Cutter Especiaily Adapted for Use on Steel Cars the Rice Manufacturing Company, Indianapolis, Ind., knownas the Red Devil rivet cutter. By its use it is claimed that?^-in. or 1-in. rivets can be cut with from three to five blowsand l}4-in- rivets in 10 seconds. The device consists of a cold drawn seamless tube ; ft, long with suitable fittings hydraulically pressed into 273 274 RAILWAY MECHANICAL ENGINEER Vol. 93, No. 5 each end. The rear end is fitted with a valve by means ofwhich air is admitted into the tubes behind the plungerwhile it e.\hausts from the forward end into a rubber by-pass. By giving the valve a quarter turn air may be admittedinto the by-pass at the forward end of the tube and exhaustedfrom the rear. At the forward end there is a bushing de-signed to provide a tit for the end of the chisel bar. Insidethe tube there is a plunger ground to fit with sufficient clear-ance to allow easy movement with a minimum amount
