For over a century, the has been the silent timekeeper of industry. While modern workplaces rely on digital logs and biometric scanners, the Cal6B Calculagraph remains a mechanical marvel—a testament to precision engineering designed to calculate elapsed time with a simple pull of a lever.
Connect to a standard grounded outlet. You should hear a faint, steady hum—this is the synchronous motor keeping the internal timing gears in motion.
Telephone switchboards (timing tolls), machine shops (job costing), and laboratories. 2. Installation and Setup cal6b calculagraph manual
Insert your time card into the front slot until it hits the backstop. Pull the forward and release. This prints the "initial" time dials. At this stage, the elapsed time pointers are at zero. Step 2: The Finish Punch
The Cal6B is a mechanical time-recording machine primarily used to calculate . Unlike a standard time clock that merely stamps the current time, the Calculagraph uses a unique internal gear system to print two or three "dials" on a card. By comparing the start position to the end position, the user can instantly see exactly how many hours and minutes have passed. Key Specifications: Drive: Synchronous motor (110-120V AC, 60Hz). Printing Method: Ribbon-based impact printing. For over a century, the has been the
The beauty of the Cal6B lies in its two-lever system (usually a left lever and a right lever). Step 1: The Start Punch
Use compressed air to blow out paper dust from the card slot. Common Issues: You should hear a faint, steady hum—this is
Invented by in the late 19th century, the Calculagraph was revolutionary because it removed human error from billing. The Cal6B represents the peak of this mechanical lineage—a bridge between the purely spring-driven models of the 1920s and the electronic registers of the 1980s.
