[Vol. XXX. No. 12. ARMATURE WINDING STAND An armature stand designed to take the place of thewooden buck and trestles commonly found in car barns andwhich embodies features of strength and convenience forwinding and repairing armatures not possessed by thebucks and trestles is manufactured by the Device Improve-ment Company, of Hanover, Pa. It consists of two cast-iron standards mounted on angle steel sills, one standardbolted stationary to the sills, the other easily adjustable toarmatures of various lengths. Each standard carries ahinged shelf which can be lowered out of the way when de-sired. The flaring bases of the standards provide small. ARMATURE WINDING STAND lockers with doors in which the armature winder can storehis tools, such as hammers, chisels, pliers, files, clips, tape,etc. The armature revolves on brass rollers, preventingany possibility of damage to the shaft and admitting easyrotation. The safety stops prevent the armature from ac-cidentally getting off the bearings while being pushedaround the shop. The stand is mounted on four large casters so that it maybe placed under chain block or hoist, and the armatureplaced in position and easily moved by one man to any de-sired location. The shelves are strong enough to be usedas seats when putting leads into the commutator, thusbringing the operator close to the work. In winding anarmature the coils may be thrown over one shelf and thearmature winder therefore has everything necessary forthe operation within easy reach without changing his posi-tion, considerations that make for speed and low cost. Anarmature to be wound or repair
