Opinion

LITTLETON, Judge. ’

The indisputable facts of record establish that plaintiff’s invention, which is the subject-matter of this suit, possesses patentable novelty and undeniably has commercial utility and advantage over the prior art, and the court so found in the former consideration of the question of validity and infringement (72 Ct.Cl. 72) and in the present proceeding on accounting. The defendant, having adopted and used the invention and obtained the benefits of its advantages, may not now deny its utility. Lehnbeuter v. Holthaus, 105 U.S. 94, 96, 97, 26 L.Ed. 939; United States v. Societe Anonyme Des Anciens Establissements Cail, 224 U.S. 309, 323, 32 S.Ct. 479, 56 L.Ed. 778; Dunkley Co. v. California Canneries et al, 9 Cir., 7 F.2d 972, 976, 977.

The claim of the patent in suit is as follows: “A gun with barrel recoil, a recoil brake arranged in only one radial direction from the axis of the barrel, and a counterpoise placed, diametrically opposite the recoil brake so that the center of gravity of the brake is thereby moved nearer to the axis of the barrel.” The recoil mechanism with which the invention in suit directly deals is located below the barrel of the gun. This location of the recoil mechanism is simpler and less expensive to manufacture than other types, and it is protected against damage from hostile fire. Such unsymmetrical location of the recoil mechanism sets up an objectionable turning couple when the gun is fired. This turning couple causes the muzzle of the gun to jump which, in turn, causes a strain on the guides of the gun barrel and undue stresses in the elevating mechanism, as well as the jumping of the gun carriage about its anchoring spade. Plaintiff’s patent discloses a form of gun construction in which the recoil brake or-mechanism is placed in this position. He provides a combination of elements by virtue of which the objectionable turning couple may be offset or counteracted in whole or in part. He does this by providing a counterpoise or weight attached to the barrel of the gun diametrically opposite to the recoil brake or mechanism. By the use of this counterweight a neutralizing couple is introduced which neutralizes the obj ectionable turning couple to a degree dependent upon the weight of the counterpoise and its location and distance from the axis of the gun barrel -as compared with the weight of the movable part of the recoil mechanism and the distance of its center of gravity from the gun axis. When the counterweight is used, it results in an ultimate saving in weight of the gun and carriage structure and in the cost of manufacture due to the reduction of the stresses and consequent reduction in size and weight of certain portions of the gun mechanism and enables the same accuracy of fire to be realized in a mobile gun with a lighter weight gun carriage and brake mechanism than would otherwise be necessary. The clear preponderance of *497 evidence in this proceeding on accounting shows that the advantages accruing to the defendant through the utilization of plaintiff’s invention in the matter of saving in weight and manufacturing costs, and other advantages of value in use, amount to $171.61 per howitzer on 2,129 155 mm. howitzers manufactured and used or acquired and used by the defendant, and we have so found. The record is voluminous and no' useful purpose would be served by a detailed discussion of evidence which establishes the monetary equivalent of these valuable features of plaintiff’s invention.

Plaintiff contends for a much greater monetary value for the benefits derived by the defendant from the use' of his invention. He claims a monetary value to the Government of $411.90 per howitzer by reduction in weight and a saving in cost of $487.13, which amounts, he .insists, constitute the reasonable monetary value of $899.04 per howitzer. This claimed value for the benefits derived from use of the invention in suit is not sustained by the evidence.
