- Gerbrands, Ralph
- Description
- This motorized instrument contains a rotating reel of paper with a recording pen tip. It has metal sides, a wooden door in front of the paper, and a plastic cover on top. The glass ink holder, as well as a mount for a second pen, are stored separately. The cumulative recorder was an improvement on the kymograph that allowed experimenters not merely to record of individual events, but acquire a cumulative record of animal behavior. It was invented by the psychologist B.F. Skinner. This is an early commercial model, manufactured by Ralph Gerbrands.
- A mark on a tag on the motor on the left side reads in part: REG. U.S. Telechron PAT. OFF. (/) MOTOR MOVEMENT (/) TYPE 1M9A-10M V 110/120 (/) MOT MOD M 1855 CY 60 W 4. It also reads: U.S. PAT 1768386 2184342 (/) TELECHRON INC. (/) ASHLAND MASS MADE IN U.S.A.
