Description Notes

Chronograph for laboratory use with three pens. All the moving parts supported on a heavy metal frame. At right hand side of frame is a drum for holding the reel of paper. Three electromagnets each with pair of terminals (one set of terminals has screw missing). Three pens attached to the armatures of the electromagnets. Below the pens is a support for the paper which would then pass between the two pulleys and feed off down the metal chute. There is a sprung lever attached to the lower pulley and another small lever which allows the pins to be raised off the paper. The larger pulley is driven by the main case pulleys on the other side of the frame.
