No crane service is necessary, andthe only labor required is that needed toload and unload the crates. It may be mentioned that the machinetakes steam on part of the up strokeonly, the remainder of the stroke beingaccomplished under the combined in-fluence of expansion and inertia, whilethe down stroke is effected entirely bygravity. The exhaust from the machine,after it has passed through an oil separ-ator, can be used for heating the places where greatest fuel economyis desired, steam consumption can be re-duced by filling the interior of the pistonrod and a cylinder located in the bottom. owing to the great reduction in the num-ber of defective sheets produced. It is claimed that by this method ofagitating the acid and material, and bysimultaneously performing the opera- mm of the base with compressed air. Mostof the dead weight of the moving partscan thus be balanced, so that a smalleiquantity of steam is required for liftingthe load in the crates.

Except when employed with thispickling machine, the two-bath systemmeets with the objection that it increaseslabor cost.
