Where it happened. (See photos 3070 to 3074), Sanders Cotton Mfg. Co., Bessemer City, N.C. In this and the adjoining mill (run by the same company) there were still many dangerous, unprotected gears, belts, belts running through the open floor, rough broken flooring on which the workers would likely stumble, etc.- when I went through these mills (October 23rd, 1912) over two months after the accident. Location: Bessemer City, North Carolina.

Washington youngster solves parking problem. Washington, D.C., March 30. Transportation and no parking worries. Nelm Clark, 16-year old Washington youngster, solved this problem by combining a lawn mower motor with a set of motor cycle gears to make this unusual midget auto. Costing $60 to build the contraption weighs only 150 pounds--the weight is its main feature--and if you run out of gas you easily push it or tuck it under your arm and walk home, 3/30/1937

Two new tools were set in the New Britain-Gridley lathe, pictured above, to adapt it for the cutting of twenty-millimeter shell booster parts. The new parts are an eccentric spindle, which may be seen attached to a driving rod in the center of the machine, and a thread rolling attachment. In peacetime, the machine was used to turn out spur gears, worm wheels and commentator rings in steel and brass
