202 F. 962 | S.D.N.Y. | 1913
This is a suit for an injunction to prevent the alleged infringement of letters patent No. 999,478, issued to Samuel B. Archer for a machine for peeling potatoes. The machine consists of a metal cylinder having a metal disk near the bottom which revolves at an angle to the sides of the cylinder, and having the interior surfaces of the cylinder and the disk coated with a granulated abradant, consisting of emery or some similar substance, in combination with the mechanism for operating the same. In practice the potatoes are put in the cylinder, and the disk at the bottom made to revolve rapidly, with the result that the potatoes are thrown by centrifugal force against the sides of the cylinder, and then fall down upon the surface of the disk, the result of which operation is that after a certain time the skin of the potato is worn off and removed. Machines embodying these general principles are old. They have been used
“The patents to Robinson, "Williams, and Mayhew disclose devices for peeling fruits or vegetables, which devices are of the same general character as that of the applicant’s, but differ therefrom in the nature of the peeling surfaces; Williams and Mayhew using metal surfaces with integral projections or burrs thereon, and Robinson using a grooved or striated metallic surface. We would agree with the primary examiner that the mere substitution of a lining or coating of granulated abradant for the burrs or striations of these devices would not involve invention, if no unexpected result attended the substitution. If such a substitution resulted in the paring of. the vegetables with the same degree of efficiency obtained'through the use of the roughened metal surfaces and no greater degree of efficiency, the applicant would merely have substituted one well-known abradant for another. The affidavit of the applicant and the accompanying report furnished by the Navy Department, filed in this case upon May 16, 1911, and passed upon by the primary examiner in accordance with the provisions of rule 141, show that a machine provided with peeling surfaces, lined or coated with a granulated abradant, developed in a competitive test very considerable and important advantages over machines having burred or striated metal for the' peeling surfaces. These results, so far as we can perceive, could not have been foreseen by those skilled in the art and clearly confer patentability upon the applicant’s machine over such references as the patents to Robinson, Williams, and Mayhew, and over any references showing merely that hard granular materials have abradant qualities, such as the patents to Davis, Patterson, and De Yasson.”
The bill is dismissed, with costs.
