m'kAT ». DIBEET. 689 �1858, for "improvement in sewing macHnes." This was a machine patent, and it claimed the invention of an improved machine for sewing the' sole on a boot or shoe. After it was issTied, to-wit, on the twenty-eighth of June, 1859, the same inventor applied for another letters patent, claiming (1) the procesB of uniting the soles and vamps of boots or shoes by the use of the said machine, and (2) the boot or shoe as a new article of manufacture made under the said process.
