Patent Model for a Self-Inking Platen Press

Description (Brief)
This patent model demonstrates an invention for a self-inking platen printing press which was granted patent number 9925. Four or more platens rotated intermittently around a single axis. The bed was rocked, clamshell fashion, against each platen in turn. Sheets of paper were fed to grippers on the uppermost platen, printed when that platen turned to the vertical, and then dropped to a pile beneath the press when the platen went to the bottom position.
