The plaintiffs, copartners under the firm name of. American Can Cutting Company, seek recovery upon a contract entered into by them with the defendant, dock company, by the terms of which they were to render services to the dock company in the opening of cans of imported oil and of transferring the oil into bulk for shipping and marketing in this country. A trial upon the merits in the superior court for King county, sitting without a jury, resulted in findings and judgment denying to the cutting company any recovery, from which they have appealed to this court.
*559Our problem is one of construction of the contract, or rather of the renewal of it. The facts are not in dispute and may be summarized as follows: On October 28, 1918, the cutting company was the owner of an invention consisting of certain machinery and a process by the use thereof for the cutting open and emptying of cans of oil and for the crushing and baling of the empty cans. The dock company was engaged in the business of operating a dock at Seattle at which were received oils imported in cans from the Orient. While it was seemingly necessary to put the oil in cans for shipment by water, it was evidently more efficient to have the oil transferred into bulk for shipment and marketing in this country. On October 28, 1918, the -contract.here to be considered was entered into between the cutting company and the dock company. After general introductory recitals in the contract evidencing generally its purpose, its terms, in so far as we need here notice them, are as follows:
“It [cutting company] will install and equip the necessary heating coils and sluicing pipes, and other appurtenances, in the dumping tables furnished for that purpose by the dock company; the number of dumping tables so to be equipped to be sufficient to handle the oil that comes to the dock for such handling. This equipment and installation of coils, pipes and appurtenances, other than the dumping tables themselves, to be at the expense of the cutting company, provided, that during the six months period covered by this contract the cutting company is furnished by the dock company with not less than six million cans of oil to be cut and emptied. If during such six months’ period the number of cans so furnished by the dock company for that purpose is less than six million, then in such event, at the end of such six months’ period, the dock company shall pay the cutting company the original cost of installation and equipment of the necessary heating coils and sluicing pipes and other *560appurtenances thereto; less fifteen (15) per cent of the same; . . . The cutting company shall furnish the dock company with the invoices or copies of same of material and labor procured in such installation or equipment within five days following the receipts of same so that the dock company have an opportunity to check the same if it should so desire. . . .
. “The operation under this contract shall commence on the 15th of December, 1918, and shall continue for a period of six months thereafter. . . .
“During the six months period covered by this contract and if this contract shall be renewed or be modified and renewed for an additional period of not less than two and one half (2y2) years, then during the period covered by such renewal, the cutting company will not use or so far as lies in their power, permit to be used their machines or process on Puget Sound for or by any other company or person than the dock company.
“It is further mutually agreed: That the dock company may have an extension of this contract for an additional period of six months upon all and singular, the same identical terms as are herein contained, provided notice of the intention to elect to have such extension shall be given to the cutting company not later than May 15th, 1919.”
. The installing of the equipment and operation thereof and the work contemplated were proceeded with by the cutting company, the dock company paying for such services from time to time at so much per can as agreed upon. During the original six months’ period specified in the contract, there were furnished by the dock company only 1,028,065 cans to be cut, emptied and crushed by the cutting company. That being less than 6,000,000 cans, the cutting company thereby became entitled to receive from the dock company the cost of installing the equipment above noticed in the first quoted paragraph of the contract, less 15 per cent. This was found and agreed by the parties to be *561$7,549.52, and was in due time paid by tbe dock company to tbe cutting company, in addition to tbe agreed compensation per can for tbe services rendered by tbe cutting company.
On June 17, 1919, tbe dock company gave to tbe cutting company notice of its election to have tbe contract extended for another six months ’ period. While this was after tbe time for giving such notice as specified in tbe contract, tbe cutting company accepted it as being timely given and proceeded with the work accordingly. During tbe second six months’ period there were furnished by tbe dock company and cut, emptied and crushed by tbe cutting company 2,022,464 cans, for which services the dock company paid tbe cutting company tbe agreed price per can. At tbe end of tbe second six months’ period, tbe dock company having furnished less than 6,000,000 cans, tbe cutting company again demanded payment for tbe cost of tbe installing of tbe equipment specified in tbe first above quoted paragraph of tbe contract, less 15 per cent, to wit, $7,549.52, recovery of which 'is sought in this action.
Tbe claim of tbe cutting company is rested upon the theory that tbe last above quoted clause of tbe contract, providing for its extension of an additional six months’ period, and tbe extension of the contract accordingly, constitutes, in effect, a new contract as if originally entered into at tbe beginning of tbe second six months’ period, accompanied by tbe installing of tbe equipment by tbe cutting company specified in tbe first above quoted paragraph of tbe contract as of that time. Counsel for tbe cutting company rely particularly upon tbe language of tbe last above quoted paragraph of tbe contract that such extension was intended to become “upon all and singular, tbe same identical *562terms as are herein contained.” We have but little trouble agreeing with this contention in so far as the contract remains executory; that is, in so far as further duties and obligations are to be performed according to its terms after the beginning of the second six months. But it seems quite plain to us that, as to compensating the cutting company for the installment of the equipment specified in the first paragraph of the contract above quoted, to the extent of the cost of such equipment, less 15 per cent, that portion of the contract has wholly ceased to he executory, hut has, in all things in that respect, been fully executed and performed by both parties; the cutting company having done all that it was required to do in that respect, and the dock company having paid all that it was required to pay with reference to the installing of such equipment. Plainly, we think the cost of the installing of the equipment, less 15 per cent, was not, under any circumstances, intended by the parties to be paid for a second time.
Some contention is made in behalf of thé cutting company that the trial court erred to its prejudice in excluding certain evidence offered in its behalf upon the trial. We deem it sufficient to say that it seems plain to us that this offered evidence would, if received and given the effect claimed for it by counsel for the cutting company, work a variation of what seems to us the plain terms of the written contract, and was, therefore, properly excluded.
The judgment is affirmed.
