Vintage McIntosh Battery & Optical Co Battery Device
Antique battery made by the McIntosh Battery & Optical Company of Chicago, illinois. This would appear to be some sort f industrial battery for maybe a medical instrument.
Dr. McIntosh founded the McIntosh N.U. Supporter Co. in the early 1870's. He also entered the medical electric field, first incorporating as the "McIntosh Galvanic Belt and Battery Co.".
His 1881 ad for this company featured a microscope convertible to a stereopticon as well as a conventional small medical battery. The company name was soon changed to the McIntosh Galvanic and Faradic Battery Co. Around 1889, the company's name was again changed to the McIntosh Battery & Optical Co.
The company offered microscopes into the 1890's, however few are to be found in collections today. Dr. McIntosh died in 1892 and the company was sold around 1897.
This is a rare survivor from an obsolete yet innovative Victorian company. I am not completely sure what it was used for but believe it was part of antique medical instruments or scientific instruments.
Antique battery measures 5“ long by 4.5“ wide by 3" thick and weighs almost 3lbs.
In good condition (please see all pictures as they form part of the condition description) and fully working when wound up. It ticks like a metronome but I do not know what the numbers refer to.
