Patent for a new and improved car-seat recorder. This design consists in "[t]he combination of the following elements: a car-axle, the depressible car-seat, and the recording apparatus arranged alongside the seat and consisting of friction feed-wheels, a paper strip, meshing spur-gears, and a puncturing device arranged vertically, a lever which operatively connects said seat and apparatus, and gearing which connects the latter with the axle, whereby movement of the car operates said apparatus and enables the record to be made by slitting the strip when the seat is depressed" (lines 22-33).
