M. Seips 1885 Cocktail Shaker

Here is an antique two piece cocktail shaker which I believe is silver plated. There is no maker’s mark on the bottom, only a number 18 or 81 not sure, and a tiny little script engraving that looks like “G5yob” (could be engraver’s mark). It measures just a tad over 8 inches tall. The cup is about 5 and 3/4 inches tall and 3 and 5/8 inches in diameter at the top.



The straining mechanism on this shaker is the same as that illustrated and described in Michael Seips’ August 11, 1885 patent (324173) assigned to Manning Bowman & Co of Meriden, CT. Mr. Seips indicated in his patent that his two piece shaker eliminated the need for a separate cap which could easily be misplaced or bent out of shape. Seips’ design greater a sliding top that when in the up position exposed the straining holes; when in the down position sealed the holes and allowed for shaking of the contents without spilling a drop.

Since there is no maker’s mark on this shaker, I do not know if its manufacturer was actually Manning Bowman. I do know that Manning Bowman did actually produce this design of shaker. Tiffany & Co. also offered this design for sale. Tiffany indicated on their shakers that the design was patented. ( Called ” Cocktail Mixer With Patent Strainer Top ” in their 1893 Blue Book). I don’t know if they entered into some sort of arrangement with Manning Bowman or if they waited for the Seips’ patent to expire and patented themselves…I have not found evidence of this.  Gorham also produced their version of this type shaker.

The full patent can be found here:


An unusual shaker based on a patent that doesn’t get acknowledged that often.
