In the 1889 lawsuit in a District Court (part of the federal court system), Densmore v. Three Rivers Mfg. Co., describes a contract made 1874-03-21 between J. Allen and J. Kelsey, with the Three Rivers Mfg. Co. where the latter licensed from the former the right to manufacture the lath machine of this patent; the complainant, Densmore (believed to be Edwin Densmore of Grand Rapids), was also a licensee of the patent. The basis was a payment of $30 royalty on each machine sold. Three Rivers Mfg. Co. also agreed to supply lath mills to Allen and Kelsey at $150 each. The complainant alleged that Three Rivers Mfg. Co. had not fulfilled its part of the contract and therefore the contract was voided. The court demurred with that conclusion and also said that they did not have jurisdiction to decide whether or not the terms of the agreement had been breached; such a conclusion was the jurisdiction of a state court. |
