Y. 186 HOISTING AND HANDLING MACHINERY. 187 that when the latch is knocked up with a shovel or hammer the weightof the material in the bucket upsets it just enough to allow the mate-rial to fall out; then the empty bucket swings back into a verticalposition and clamps itself. These are much used on ordinary derrickwork, the 2 cubic-yard size being very AN EXTRA HEAVY by Page & Schnable. In New York the laborers or cellar diggers shovel the materialinto the bucket which the derricks hoist over the wagons, where it isdumped; the wagons being in turn dumped onto scows, making thehandling of the cellar excavation run up to $2 or $3 a yard as against25 cents in the country. Working these buckets should soon showthe advantages of the clam-shell, orange-peel, and similar formswhich feed themselves, doing away with much expensive labor andthe waste of time in waiting for the derrick, and in other delays. These self-filling buckets have two or more parts which are low-ered on to dirt, coal, gravel, sand, ore, etc., with wide-open jawswhich shut up as soon as hoisting begins, but not before they havescooped up a full load. Many mechanical devices are used to operate these jaws, and onthe larger sizes pneumatic power is used. A i cubic-foot orange-peelbucket costs about $100 and is useful in cramped quarters, such as
