Canada

USED EXTENSIVELY IN CANADA, AND AROUND THE WORLD. THIS EXAMPLE WAS USED BY BELL CANADA, ALTHOUGH THE EXACT LOCATION IS UNKNOWN.

Function

USED TO TIME LONG DISTANCE TELEPHONE CALLS FOR CHARGING PURPOSES.

Technical

BASED ON AN 1897 U.S. PATENT, THE MODEL 6 CALCULAGRAPH IS CLOCKWORK DRIVEN AND AUTOMATICALLY CALCULATES AND PRINTS THE ELAPSED TIME BETWEEN THE START AND END OF A CALL. THE MODEL 6 WAS INTRODUCED BEFORE 1900 AND WAS MORE OR LESS REPLACED BY THE ELECTRICALLY DRIVEN MODEL 30 IN 1930. MANY CONTINUED TO BE USED FOR YEARS, HOWEVER, SO IT IS VERY DIFFICULT TO DATE A PARTICULAR UNIT ACCURATELY. THIS UNIT IS MOUNTED IN A SWITCHBOARD STRUCTURE DESIGNED TO BE PLACED IN A SWITCHBOARD LINE-UP. THE CABINET IS PHYSICALLY AND VISUALLY COMPATIBLE WITH THE 105B MAGNETO SWITCHBOARD.
