Object Details
- American Arithmometer Company
- Description
- This relatively early example of a Burroughs full-keyboard printing manually operated adding machine was collected by the rival firm of Felt & Tarrant Manufacturing Company.
- The machine has a ferrous metal frame painted black, with glass sides that reveal the metal mechanism. This mechanism includes a dashpot, a device for cushioning a movement to avoid shock.. There are nine columns of color-coded black and white plastic keys, with two black keys for cents, three white keys for dollars to 999 dollars, three black keys for thousands through 999,000 dollars, and a ninth, leftmost column for millions of dollars. The metal total key is left of the keyboard, and metal error and repeat keys are right of the number keys. The keyboard is covered with green felt. The machine is operated by bringing forward a metal crank with a wooden handle that is on the right side.
- The printing mechanism is at the back of the machine. The carriage is 10 1/4" (26 cm.) wide, and the results printed are not visible to the operator. This carriage can be set in six different positions. It has a pinch roller release to adjust a single sheet of paper, as well as adjustable paper guides. An adjustable release is on the left side at the back. A smaller carriage for rolls of paper 3 1/2” wide. A saw-toothed edge allows one to tear off part of the roll of paper. A row of nine number dials at the front of the machine, inside the case, shows the running total. This machine lacks a paper tape, apparently has no ribbon, and is missing a portion of the glass on the right side.
- The Class 1, Style 3 differs from the other Burroughs Registering Accountant received from the collections of Felt & Tarrant Manufacturing Company in having a wide movable carriage, separate error and repeat keys, and a register showing running totals at the bottom front of the machine.
