The patent was originally issued to Edwin J. Howlett and Susan M. Kirk, and was re- issued to Edwin J. Howlett, as assignee. The answer denied that the re-issue was for the same invention that was described in the original patent, pr that Howlett was a joint inventor, and alleged anticipation of the devices therein contained. �J. li. Bennett and George Harding., for complainant. �P. K. Erdman, F. A. Lehmann, and J. J. Combs, for re- spondent. ■ �Butler, D, J. Claitns 2 and 5 of the plaintiff's patent, are, very elearly, for equivalent devices. The blade B, and the plate E, are intende(^ for separate, independent use. When the former is detach^d ^nd removpd, as contemplated to be when not in use, the latter supplies its place, and per- forms its oESce. Both cannot be used at the same time. Paragraph 14 of the specifications, and the testimony of the experts on each side, as well as an examination of the plain- tiflf's drawings and model, show that one of these devices is the mere equivalent of the other. The complaint, as exhib- ited by the testimony, and urged by counsel, is that the de- fendants have infringed the fifth claim. It goes no further. �*Keported by Frank P. Prichard, Esq., of the Philadelphia bar. ��� �
