Telegraph Register - Wasserlein, Inking, late 19th Century Reg. No: ST 007094
- Telegraph inking register for receiving and recording telegraph signals.
In operation, the intermittent current generated by the received signals causes a small rotating wheel to be intermittently pressed on to a moving paper tape. The wheel is also in continuous contact with a small fabric roller saturated with ink. The rotating wheel carries the ink to the paper and produces a series of long and short marks on the tape, with the length of each mark depending on whether the duration of the current flow is long (producing a dash) or short (producing a dot.)
The register mechanism is driven by a falling weight attached to a chain passing over a sprocket on the main drive shaft.
- Wooden baseboard. Two vertical coils at one end of baseboard. Gear mechanism enclosed in brass case with inking mechanism mounted above case. Arm with spindle to hold reel of paper tape attached to side of brass case. Various terminals for wire connections.
