20 F. 315 | U.S. Circuit Court for the District of Southern New York | 1884
This suit rests on reissued patent No. 4,479, dated July 25, 1871, granted to John Ashcroft, for an improvement in processes for treating coffee, division A. The process consists, essentially, in subjecting unripe or damaged coffee to the direct action of steam in a close compartment to heat and sweat it, and then to dry heat to complete the curing of it. There are four claims. The first claim is, in substance, for the process of maturing and browning coffee by subjecting it to the direct action of steam; the second, the process of maturing and browning coffee by subjecting it to the sweating and expanding action of steam and the drying action of hoat; the third, subjecting it both to the action of steam and beat while in sacks; and the fourth, subjecting a series of sacks to the action of sweating steam and drying beat. The defendants subject the coffee to the action of heat in a close compartment. The beat raises steam from the moisture of the coffee and produces a result similar to that ■of the process of the patent. The orator’s evidence tends to show that this process, taken by itself, is the same as that of the second claim and, in connection with the result, the same as that of the third claim of the patent. The witness giving this testimony is understood, however, to refer to these claims as measured by their own terms, which do not refer to the source of the steam. His meaning, apparently, is that the steam generated from the moisture of the coffee performs the office of steam applied from without. But this does not alter the
Let there be a decree dismissing the bill, with costs.
