TECHNICAL DATA of the A M E R I C A N A D D I N G M A C H I N E ************************************************************************* 7 / 8 Serial Number: 0032221 Dimensions: (ca.) Width = 9_1/4" / 24 cm Depth = 9_1/4" / 24 cm Height = 9_1/4" / 24 cm Weight: (ca.) 16 lbs / 7.3 kg Manufacturer: AMERICAN CAN COMPANY ADDING MACHINE DIVISION Chicago, Illinois / USA 1913 H O W T O U S E the AMERICAN ADDING MACHINE **************************************************** Clear the Arithmetic: --------------------- (1st) Pull & hold the right (outside) crank; (2nd) Pull the MAIN-LEVER; Release the (outside) crank. ( ATTENTION: The arithmetic will be cleared also after a ZERO INPUT !) Enter & Add a Number: --------------------- To enter a ( 7 DIGIT ) number, it is supposed, that the operator placed his index finger on the figure desired and than placed the thumb on the lever directly below. Then lift the thumb until it touches the index finger. After enter all figures, pull the MAIN-LEVER to add the number to the ( 8 DIGIT ) memory. Make sure to push back the MAIN-LEVER in full: NOW (!) the 10s-CARRYs will be processed - and the input will be cleared. Repeat a Number: ---------------- Enter the number. Pull the left lever (= REPEAT-LEVER ) until it locks. Pull the MAIN-LEVER. In the round window left under the input-levers a REPETITION-COUNTER get active ( 0 .. 9 ). Release the REPEAT-LEVER b e f o r e the last input. Subtraction: ------------ Only ADDITION is performed. For SUBTRACTION 9-Complement "Addition" has to be used. ( For DETAILS see the INSTRUCTIONS to the BURROUGHS ... ) R E M A R K S TO "PAY ROLL DISTRIBUTION ... " ----------------------------------------------- It reads: 10$/25ct .. 5$/10ct .. 2$/5ct .. 1$/1ct What is the MEANING of it = ??? = Just DECORATION G U E S S : May be it refers to making COIN-ROLLS to give to a bank ... 40 x Quarters (= 25 ct) = 10 USD 50 x Dimes (= 10 ct) = 5 USD 40 x Nickels (= 5 ct) = 2 USD BUT: { 50 x Pennies (= 1 ct) = 50 ct } x2 = 1 USD ??? Have a look at "Calculating Trickies" ...
