Home-Made Armature-BandingTensioner A home-made device which provides about in the armature-banding wire, has been con-structed by the mechanical department of the Gales-burg Railway, Lighting & Power Company, Galesburg,111. This tensioner con-sists of sixteen steelspools, 1 in. in diameter,mounted on bearingsset on a steel bar at 1 Va-in, centers. As shownin the accompanying il-lustration, this bar isbent to form a clamparound a pipe wire is threadedthrough the spools inthe usual manner, andthirteen spools are usedto obtain 250-lb. tensionin the banding supply of band
