Enforcing Jobbing Foundry Economies— The buyer is wielding the whip on the backward foundry—the foundry whose costs do not permit successfulcompetitive bidding. Only those foundries can achievea profitable volume which can meet their competitors onthe bed-rock of greatest operating efficiency. Osborn Moulding Machine practice permits a jobbingfoundry to save a worth-while profit even on worktaken at a figure which would leave no margin for afoundry operated on hand-moulding. Facts—figures—and examples of actual production im-provements are given in detail in our new foundry book,All in a Days Work. The Osborn Manufacturing Company New York INCORPORATED CLEVELAND San Francisco On this 775 lb. casting a jobbingfoundry pocketed the following sav-ings as soon as it changed over tomachine-moulding.
