Duesh v. A. J. Medlar Co.
Opinion of the Court
The suit is for infringement of claims 1, 6, and 7 of letters patent No. 90,577, issued May 25, 1869, to Joseph Rcpetti, for cracker-machine; and also for infringement of claim 8 of letters patent No. 209,963, issued to Henry Duesh, November 19, 1878, for improvement in soft-dough machines. The claims of the first patent here involved road as follows:
“The combination of the automatic stopping device, consisting of the finger, l, rock-shaft, i, arms, h and h', rod, d, spring,/', and stopper, g, with the plunger, j, screw, k, and pulleys a and a’, or their equivalents, substantially as and for the purpose herein described. (6) The combination of the bevel wheels, 7 and 8, hand wheel, 9, with non-rovolving screw, k, revolving nut, z, and plunger,,?, substantially as and for the purpose specified. (7) The combination of the slide, 6, with the movable bottom, y a, and dough-box, 10, substantially as and for the purpose set forth in this specification. ”
As respects the claim of the Duesh patent, here involved, it is sufficient to say that no infringement is shown. The patentee is clearly confined to a “ tape-váre ” knife, in his combination. This the defendant does not use. Although the words “tape wire” are not found in connection with knife, in the third claim, the knife there referred to is the same knife described in the first claim as a “ tape-wire knife.” The specifications clearly disclaim a round wire, such as the defendant employs. “ I am aware that it is not new, broadly, to cut dough by means of a round wire, and such I therefore do not claim; the gist of my invention consisting in the use of a tape-wire knife,” says the plaintiff.
The many other questions discussed need not be considered. The bill must be dismissed, with costs.
