Burroughs Payroll Segregator
- Description
- In the first half of the 20th century, many workers were paid in cash. Businessmen needed to know the coins and bills they would need to meet their payroll. This device, invented by John Magnus of Burroughs, was designed to carry out such calculations. It has seven columns of black and white color-coded plastic keys. The keys in each column are numbered from 1 to 9. The front of the machine has ten sets of numeral wheels labeled with denominations of money from 1 cent to $10. Knobs on the right zero the wheels.
- A red paper tag attached to the object is marked: PATENT DEPT. (/) #45. The machine is marked on the front: BURROUGHS (/) PAY ROLL (/) SEGREGATOR. A metal tag attached to the base of the keyboard reads: B.A.M.CO. (/) MODEL (/) NO. 401.
