HOME MADE PIPE BENDER A pneumatic pipe bender with several novel features is- inuse in the car department of the Danville shops of the Chi-cago & Eastern Illinois. The device, which is shown in theillustration, bends pipes to any angle desired without heat-ing and without the use of springs or sand to prevent bends can be made at one time en certain classes of Sllad. Parts Formed in One Operation on Pneumatic Pipe Bender work, as for instance in forming the offset in the train lineto pass over the Cardwell draft gear spring. The device consists of a 14-in. air cylinder, the pistonof which extends out over a hea\y iron plate. The pistonis arranged to carry grooved dies of various sizes and theplates carry three grooved rollers, set on studs, which canbe shifted to various positions, ki one side of the plate isa movable arm which carries a fourth roller mounted on an
