Mechanical Accountant Company

This little known competitor appeared on the key-driven calculator scene 
around 1902. Located in Providence, RI and producing what is probably the 
earliest key-driven machine with two registers, it seems to have survived 
until at least the mid 1920s. Very little is known about model or serial 
number chronology or the history of the company.

Our only sources of information is the American Digest of Business Machines 
and Martin. Apparantly the side mounted short-stroke clearing lever would 
zero both dial-sets, each of which was protected from external contaminants 
by a clear, full-width, curved plastic piece. In contrast, both the 
Comptometer and Burroughs machines had their plastic protectors mounted 
beneath apertures in the register cover.

Both Martin and McCarthy tell us that the upper set of dials was for the 
"last item set up on the keyboard" while a bar at the bottom of the 
keyboard is for clearing the "register dials only". Unfortunately, this 
last seems to be in error. We have it from Larry Wilheim who has two of 
these rarities...

"...the bar across the bottom clears the individual item or top dial."

In discussing this machine, Martin states flatly "the designer is 
J.A.V.Turck" who joined Felt & Tarrant at some point before 1913. 
How this competitor managed to stay in business well into the 1920s 
producing so few machines and without their original designer seems 
a mystery.
