Masury & Sons of NY Patent date of Dec 6 1873
Cast iron implement with a crank turned gear shaft. I'm guessing a workshop or kitchen use tool.Looks as though it was wall mounted with the round wheel at the top.Plunger shaped disk at the bottom is about 3" in diameter.
It may be for putting lids on paint cans, or removing the contents of the can, the latter being most likely.
John Wesley Masury (1820-1895) was a successful paint manufacturer who also invented and patented a number of paint-industry innovations, including a water-cooled method of grinding pigments, metal paint containers and the lip-closure on paint cans, still referred to as the dripless can, that made the marketing of ready-mixed paints feasible. The letters patent granted to John W. Masury, July 12th, 1859, for an improvement in paint cans. The claim of the patent:
The construction of a metallic can, for hermetically sealing paints and other substances, having attached thereto a rim or ring of thin brass or other soft metal, in such a manner that the top or cover may be removed by severing the said rim or ring of brass or other soft metal with a penknife or other sharp instrument, in the manner and for the purposes ...
The result? An enormous growth of the paint industry then began in the 1860s, stimulated by the above invention of modern the paint can. The first factory-made paints in cans consisted of more finely ground pigments in an oil base; after purchase, additional oil was added to the contents of the can to make up the paint. Such paints saved the time of handgrinding pigments. After 1875, factory-made paints were available at a reasonable cost and, as a result, greater numbers of people painted and decorated more of their buildings, and more frequently. The new commercial market created by ready-mixed paint became the cornerstone of the modern paint industry. The company became "John W. Masury & Son" in the 1870's.
Here is one patented by F.L.Miller with a similar rack & pinion.

Glad someone explained that.........I thought it was an original prototype of a mam-o-gram machine. Live and Learn
@ fhrjr2, all they needed was the invention of the x ray machine.
