See the introduction to this "Canning Jars" section previously mentioned for standard manufacturing similar diagnostic dating info for canning jars.
One of the wonderful range of canning jar closures, there have been not less than 3 normal classes of "lever" form closures: cam levers, basic levers, and clutch levers. These standard varieties worked via the motion of a lever (cope with) to apply pressure in a few manner to carry the lid tightly against the sealing surface. See Toulouse (1969a) The Collectors' Guide to Fruit Jars book for more information. The 1st lever type patents for canning jar closures have been issued during the early 1860s with different Other people issued from that time until eventually the early 20th century.

 Generally speaking, the courting of such type bottles determined by producing similar diagnostic features follows rather effectively the tips presented through this website and summarized over the Bottle Dating page; see that webpage To learn more.
These groove ring wax seal finishes, regardless of the specific production technique utilized (talked about afterwards), seem when hunting down in the rim of your finish being two circular and parallel ridges with the indented groove separating them. This groove was known as an "annular groove" by early glassmakers.
 Also, these typing pages can only scratch the area of your diversity of any group - like canning jars. Contrary to most visit homepage other foods bottle categories, canning jars have in fact obtained major notice from researchers. The remarkable variation in jar brands, and in particular, the hundreds of different closure styles, has piqued the interest of collectors and researchers for decades and impressed numerous authors to solution this classification with zeal and investigation depth (Toulouse 1969; Creswick & Rodrigues 1969; Roller 1983; Creswick 1987; Other folks). As well as figured flasks (McKearin & Wilson 1978) And maybe Western liquor bottles (Thomas 1974, 1977, 1998a & b, 2002), canning jars have had several of the most effective historical study accomplished on them nevertheless all of the "fantastic" guides are very long away from print.
So, what do these bits of knowledge increase approximately? Even though the makers mark of S. G. CO. could conceivably stand with the names of a number of glass firms (most during the eastern U. S.), given the believed age in the bottle (nineteen twenties or 1930s) and The placement on the diary person (south central Oregon) the initials Virtually unquestionably suggest generation from the Southern Glass Enterprise (La, CA.) which was in small business from 1918 to about 1930 and was known as a milk bottle producer (Toulouse 1971; Lockhart et al. 2009b). Understanding the maker narrows the manufacturing time down a tad extra. Even so, the quantities about the rim in the end are rim date codes - a bottle monitoring strategy employed by West Coast glassmakers within the mid-1920s to early 1930s - indicating this bottle was built in February ("2") of 1925 ("five").
