Siiftlied by lulenuilioiial Film Scr::^c Camouflaged Freight Cars for Carrying l\^unitlons to the Front In France AIR HAMMER ATTACHMENT Mister Mecha BY J. S. BREYERc. Southern Railivay. Charleslon. S. C. The air hammer attachment shown in the illustration isfor use in splitting nuts on grab irons and ladders when dis-mantling cars for hea\y repairs. The device consists of a piece of 1-in. square iron forgedat one end and in the shape of a yoke around a hammer, andat the other end bent at 90 deg. as indicated. Xear the endof the barrel of the air hammer there is a collar which fits outer end of the slide carries a centering guide and a boxtool, which is adjustable to various sizes. The split diecarries the usual set of four chasers and also a nicking tooloperated by a lever, which is used to form a recess underthe head of the stay. Ihe details of construction of thedie head are shown in Fig. 2. The usual mechanism for. Nut Splitting Attachment for Thor Hammer into a groove 3-2-in. wide by J-g-in. deep, and is the stop fora 3/16-in. coil spring. The purpose of this spring is to holdthe hammer and chisel against the yoke, and as the yoke fitsclosely around the barrel of the hammer, there is no dangerof the chisel shooting out and causing an accident. In operation, the end of the yoke, which is bent to an angleof 90 deg., is hooked around one side of the nut and the chiselbrought to bear on the opposite side. The air hammer triggeris then pressed, which operates the chisel and very quicklysplits nuts up to ?.s in. in size. AN EFFICIENT MACHINE FOR FINISHINGCROWN STAYS The finishing of crown stays is a job for which standardt}-pes of machines are not well adapted.
