 368 FBDEBAI. EBPOETEB. �This was a bill in equity oomplaining of the infringement of re-issued letters patent No. 5,630, for an improvement in coupling and steering eanal-boats. The respondent denied the novelty of the invention, and alleged also that the re-issue was for a different invention from that described in the orig- inal invention. The case was heard on bill, answer, and prpofs. �J. J. Comhs, for complainant. �Henry Baldwin, Jr., for respondent. �Pbb Cueiam. The bill here is founded upon a re-issued patent to the complainant for "improvement in coupling and steering canal-boats." �This re-issue is alleged to be invalid, as being for a differ- ent invention from that described in the original patent. The difference between the two patents consists in a slight change in the points of attachment of the coupling and centering chain, D, to the stem of the forward boat, which appears only in the drawing attached to the re-issue. It is altogether immaterial, inasmuch as the mode of operation, the manner of construction, or the function performed are not in anywise affected. �The remaining defences do not require a detailed discus- sion. It must suffice to say that they are not sustained. �The allegation of infringement is supported by satisfactory evidence, which the respondent's proofs have not overthrown, and none of the prior patents exhibited cover the complain- ant's invention. �There must, therefore, be a decree for the complainant; but, inasmuch as the allowance of an injunction would cause much greater injury to the respondent than benefit to the complainant, the decree will be only for an account. ����
