This is an unusual antique julep strainer that is marked “C. J. Hauck & Son, Brooklyn, N.Y., Pat. Jan. 14, 90.” It measures approximately 5 and 1/2 inches in length and the bowl measures approximately 3 inches wide and 3 and 5/8ths inches long.
C. J. Hauck was a manufacturer of fancy metal goods at his Brooklyn, N.Y. location in the 1860s. His son, Edward, obtained a patent for a cocktail shaker in 1884, and another son, Charles Jr., obtained a patent for this variation of a julep strainer on January 14, 1890. This photo was taken with a copy of that patent as a background. The handle of the strainer shown here appears to have been modified somewhat in the past…perhaps by a bartender long ago.
I have written a blog post about J. C. Hauck, including patent illustrations, which can be found here:
