512 FEDERAL REPORTER. �Prary & Clark made the above-described change in their coffee-mills? It cannot be shown, and, indeed, it is not pretended, that the change is an improvement to the mill, or that thereby the cost of manufacture is lessened, or any other advantage is gained or useful purpose subserved. Manifestly the sole object is to produce a mill of which it can be affirmed that the hopper and grinding-shell are not cast integral, or formed m& single piece literally. But "the letter killeth;" and if the justice of the case is not to be sacrificed, regard must be had to the spirit rather than the phraseology of Strobridge's first claim.

He says: "In the ' French mill' the grinding-shell is not united or fastened in any way to the hopper ; but, on the oontrary, it is a loose and detached piece, which is held in its place and relation to the hopper by a metallic strap or step, bent to the shape of, and extending aoross and below, the said shell, and fastened ��� �
