The consideration expressed in the conveyance of the interest in the patent by the plaintiff to the defendant was not conclusive upon the parties. Either party was at liberty to show the true consideration of the transfer. (Adams v. Hull, 2 Denio, 306, and cases cited.) It follows that the defendant was at liberty to show that he was not to pay twenty-five hundred dollars for the interest in the patent only, but was to have, in addition thereto for that sum, the right to use the improvements already invented by the plaintiff, and the right to further suggestions of the plaintiff in perfecting the machine. The objection of the plaintiff to the evidence, upon the ground that it contradicted the writing, was properly overruled. It must be borne in mind that the defendant did not execute the writing; that it was a mere conveyance of the interest in the patent by the plaintiff to the defendant, reciting the consideration. The evidence was also objected to as inadmissible under the answer. This objection was not well taken. The allegation in the complaint in substance was, that the defendant promised to pay the plaintiff twenty-five hundred dollars in consideration of the transfer of his interest in the patent. This was denied by the answer. Under this denial the defendant had the right to prove any thing that would *Page 265 show the allegation untrue. The proof offered did so show. It proved, that, for the twenty-five hundred dollars, the defendant was to have not only the interest in the patent, but also the improvements of the plaintiff and his further aid in perfecting the machine; and that the plaintiff was not entitled to the twenty-five hundred dollars upon conveying his interest in the patent merely, but was to perform other acts in addition thereto, for that sum. The evidence was, therefore, admissible under the denial of the plaintiff's allegation. The defendant having admitted sales of the right to use the patent, to an amount sufficient to entitle the plaintiff to recover the fifteen hundred dollars, provided he was entitled to such recovery upon the other facts of the case, it was immaterial what he received upon the sale of any particular writing. It was not error, therefore, to exclude such evidence. The defendant did not rely upon the fact, that the plaintiff had procured a patent for his improvements to the machine, to show the breach by the plaintiff of his contract, to permit the defendant to use such improvements. His refusal was proved by other evidence. The consent of the defendant to the obtaining of such patent was, therefore, immaterial. The real question in the case is, whether the referee was correct in finding that the agreement of the defendant to pay the plaintiff the further sum of fifteen hundred dollars was conditional upon the plaintiff giving to the defendant for his use, his improvements of the machine, and his further aid in perfecting it. This question has been very ably argued by the counsel for the appellant. But the exception to the report is too general, according to the settled rule, to authorize this court to review this or any other question arising upon the report. (Newell v. Doty, 33 N.Y. 83.)
The judgment appealed from must be affirmed, with costs.
