St. Louis Cash Register


This cash register has a wooden case with glass-covered pop-up indicator numbers at the back. A metal lever that moves laterally across the front of the machine points to multiples of 5 from 5 to 95. On the right is an auxiliary lever for indicating amounts from 0 cents to 4 cents. On the left is another auxiliary lever for indicating 0, 1, or 2 dollars, hence the cash register indicates amounts up to $2.99. When the pointer-lever is depressed, the dollar, multiple of 5 cents, and 0 cent to 4 cent amounts are indicated on separate indicators at the back of the machine.

A window in the front of the machine is above the scale for the pointer. It is supposed to be covered with a shutter which can be opened only with a lock and key, keeping a secure record of transactions. No lock or key is evident.

The wooden cash drawer has six compartments for coins and three for paper bills. A spring at the back of the drawer keeps it in place.

The Model 106 is not listed in McCarthy in 1924, although other St. Louis cash registers are. The company is not mentioned in the 1928 edition of the book.
