The illustrations show the Motorbloc built on a Franklin-Moore all-steel suspension spur-geared chain hoist. For oc-casional use at points where electric current is not available,or in the event of the temporary failure of electric power,the hand chain can be quickly applied, and the hoist oper-ated as an ordinary block. Decembef, 1922 RAILWAY MECHANICAL ENGINEER 731 Heavy Type Pneumatic Flanging Machine THE pressing demand for a pneumatic flanging machinewhich would successfuUy flange the heavy plates nowbeing used in the construction of locomotives,prompted the McCabe Manufacturing Company, Lawrence,. New McCabe Machine Which Flanges ?4-ln. Boiler Plate Cold Mass., to build a heavy t)-pe machine shown in the illus-tration. This machine will flange cold any thickness ofboiler plate up to and including ^ in. Circular heads, halfheads, dished heads, segments of circular heads and straightflanging are flanged cold. Corners varjing from 1J4 in-radius tt) 8 in. radius are flanged in one heat and with onecomplete stroke of the bending ram. The new McCabe flanging machine is equipped with apatented pneumatic plate damp. This clamp eliminates mostof the manual labor that was required in the former adopting this new clamping de\ace, the speed of flangingcircular work has been increased over 50 per cent. Themachine is of cast steel construction; is self-contained; re-quires no foundation; and can be operated anywhere aboutthe shop within range of the air system. All that is requiredto put the machine into operation is an air hose (100 ) and
