C. Paul Parker, of Chicago, Ill. (Lionel V. Tefft, of Peoria, Ill., and Francis C. Downey, of Kansas City, Mo., on the brief), for appellants.
Eugene A. Thompson, of Syracuse, N. Y. (Denison & Thompson, of Syracuse, N. Y., and Henry S. Conrad, of Kansas City, Mo., on the brief), for appellee.
Before BOOTH and GARDNER, Circuit Judges, and MUNGER, District Judge.
This is a patent suit in the conventional form, the defenses being invalidity of the patent and noninfringement.
The trial court dismissed the bill on the ground of noninfringement, the validity of the patent not being passed upon.
The patent involved is No. 1,288,694, issued December 24, 1918, to Simon E. Schroeder and Charles W. Bird, entitled "Driving Mechanism for Operating Devices."
The specifications state:
Claims 10 and 11 only are involved. Claim 10 reads as follows:
Claim 11 reads as follows:
The two main elements upon which the present suit turns relate to the support of the wringer in connection with the detachable driveshaft. They are thus stated in claim 10: "* * * A vertical drive shaft in said support, provided with a seating member at its upper end formed for clutch engagement with an opposing member adapted to be positioned relative thereto at varying angles about the axes thereof; * * * a sleeve member suitably connected to the operating mechanism and supporting said short shaft and fashioned for seating upon the seating member of the drive shaft * * *."
The patentee was well acquainted with the prior art covering wringers attached or attachable to washing machines.1
It is thus apparent from the excerpts that swinging wringers were old in the art.
If further proof is needed, it is found in Cooling, No. 1,340,328; in Schroeder, No. 1,048,215; and in Winger, No. 1,070,761.
Detachable drive shafts were also old in the art. Greenlief, No. 1,082,745, discloses one; Wenzelmann, No. 1,118,980, discloses one; and the evidence shows that the Dodge and Zuill wringer, in use before the application for plaintiff's patent, also disclosed one.
We come then to the combination of the elements as described in claims 10 and 11. These claims were added in the Patent Office. They were both rejected on the reference Wenzelmann. The claims were then modified and were again rejected on the references Greenlief and Winger. They were again modified and applicant's attorney stated as follows: (Italics ours.)
It is apparent that claims 10 and 11 were carefully and closely examined in the Patent Office, and allowed only when narrowed and limited to the form in which they now appear.
The same narrow construction must follow the claims after the patent is allowed.
In the case of Phoenix Caster Company v. Spiegel, 133 U. S. 360, at page 368, 10 S. Ct. 409, 412, 33 L. Ed. 663, the court said: "It is well settled that, where a patentee has modified his claim in obedience to the requirements of the patent office, he cannot have for it an extended construction which has been rejected by the patent office, and that, in a suit on his patent, his claim must be limited, where it is a combination of parts, to a combination of all the elements which he has included in his claim as necessarily constituting that combination."
