ALLIS-CHALMERS MANUFACTURING CO. v. KENNEDY, 25 F.2d 1017 (3rd Cir. 1928)


ALLIS-CHALMERS MANUFACTURING CO., Appellant, v. Joseph E. KENNEDY, Appellee.

No. 3740.Circuit Court of Appeals, Third Circuit.
April 30, 1928.

Appeal from the District Court of the United States for the District of Delaware; Hugh M. Morris, Judge.

Decree (21 F.[2d] 530)
affirmed.

Clifton V. Edwards, of New York City, George F. De Wein, of Milwaukee, Wis., and William G. Mahaffy, of Wilmington, Del., for appellant.

Thomas Howe, of New York City, and E.E. Berl, of Wilmington, Del., for appellee.

Before BUFFINGTON, WOOLLEY, and DAVIS, Circuit Judges.

BUFFINGTON, Circuit Judge.

In the court below Kennedy, the owner of patent No. 1,436,338, granted November 21, 1922, to Charles L. Carman for a crusher, charged the Allis-Chalmers Company with infringement thereof in a gyratory stone crusher of its make. In a comprehensive opinion that court held the patent valid and infringed. On appeal from a decree so holding we find ourselves in entire accord with that opinion, only adding that we find Carman’s device increased output as much as four to one, and avoided the wear, tear, and rapid depreciation incident to the use of prior crushers.

In view of the full and satisfactory discussion the questions in the case have already had at the hands of the court below, we limit ourselves to now stating the decree is affirmed.
