Mason’s LGCo (Monogram) Patent Nov 30th 1858
Patent Nov 30th 1858
Provenance: Patricia Sprang Collection
John Landis Mason, in New York City, received a patent for his screw-finished jar on November 30, 1858, When Mason’s patents were due to expire in 1871 and 1872, he sought and obtained a seven-year extension. From that point on, just about everything about his invention and patent is confusing as Mason’s patent extension was transferred to the Consolidated Fruit Jar Company (CFJCo). This extension only covered patent protection until the end of the 1870s. The Consolidated Fruit Jar Co. registered a trademark for Mason Jars on October 28, 1879, attempting to continue to control the manufacture and distribution of the jars. In this gray area, numerous other glass houses made Mason jars with the 1858 embossed patent date during the 1880s and 1890s. It is likely that CFJCo lost control of the market.
The OMEGA jar is hand blown with a ground lip. The closure is a shoulder seal with a zinc screw cap with a milk glass liner. The quarts come in various shades of green and blue aqua along with citron. Our museum example is unusually rich and deep in glass color. The midget pints can be found in aqua. In many cases, the glass has character or whittle.
The maker of the Mason’s LGCo monogram Patent Nov. 30th 1858 jar is unknown. Many glass houses embossed a fancy monogram on the molds they were using to blow their own jars. Some jar authorities, in the past, thought it might stand for Lamont Glass Co. the Louisville Glass Co. or the Lindell Glass Co. in St. Louis. Some are not even sure of the exact order of the letters in the monogram.
