“ The disintegration aimed at by the statute does not extend to reducing all manufacture to isolated units of the lowest degree. It is as lawful for one corporation to make every part of a steam engine, and to put the machine together, as it would be for one to make the boilers and another to make the wheels. ”

“ It is said that from 70 to 80 per cent of all the shoe machinery business was put into a single hand. This is inaccurate, since the machines in question are not alleged to be types of all the machines used in making shoes, and since the defendants' share in commerce among the states does not appear. But taking it as true, we can see no greater objection to one corporation manufacturing 70 per cent of three noncompeting groups of patented machines collectively used for making a single product than to three corporations making the same proportion of one group each. ”

“ Instead, they only let machines, and on the condition that unless the shoe manufacturers use only machines of the kinds mentioned, furnished by the defendants, or if they use any such machines furnished by other machinery makers, then all machines let by the defendants shall be taken away. This condition they constantly have enforced. ”
