Description: |
| This patent was the subject of infringement litigation, Edna Brass Mfg. Co. v. Wiltbonco Mfg. Co., Massachusetts District Court, decision date 1923-08-01. The plaintiffs had been assigned this patent, which is "related to an improvement in water gages, which consisted chiefly of a single removable yoke or hook for holding the two parts of a gage together. The defendant's gage did not have a single removable hook, and can be considered an infringement of the Mauger patent only by giving that patent a liberal construction... The pioneer patent in the art was granted to Klinger in 1892 (patent 470,850), which related to a method of ribbing the glass so that the water could be seen more easily on account of the refraction of light. The manner of attaching the two frames together was only incidental to the invention... Many attempts were made to provide a connection such that the gage could more easily be taken apart, and several patent were granted for improvements in the means of connection..." The decision was in favor of the defendant. The decision was appealed; the First Circuit US Court of Appeals affirmed the lower court's decision. |
