The Metal Chips and Heads of Rivets When Cut OffAre Caught in Wire Baskets with Wooden Handles CUTTING off rivet heads is a strenu-ous occupation. Bits of metal arelikely to fly in unlooked-for directions,sometimes injuring bystanders veryseverely. Safety engineers on the SouthernPacific Railroad figure that loose rivetheads flying around with the speed ofbullets are not conducive to the generalgood health and well-being of em-ployees or of the public. Hence they have equipped alltheir rivet-cutting gangs with wirebaskets mounted on long woodenhandles. When using one of thesedevices, a rivet-cutter angles forthe head when it comes off in muchthe same way as entomologistsand youngsters seek to capturemoths wilh butterfly nets—in fact,the rivet baskets and a professorsbutterfly net look a good dealalike. At any rate, the baskets haveproved themseKes to be a sure pre-ventative of flying rivets; for theycatch their prey before it has flownsix inches—thus effe
