Felt & Tarrant Mfg. Co. v. Mechanical Accountant Co.
U.S. Circuit Court for the District of Rhode Island
In Equity. Suit for infringement of letters patent No. 371,496 for an adding machine, granted to D. E. Felt October 11, 1887. On motion for preliminary injunction.
1Opinion of the Court
BROWN, District Judge.
