Patent Model for a Hand Press

Morse, Jedediah · ca 1857

This patent model demonstrates an invention for a hand press which was granted patent number 18527. The platen was lowered by a series of conical rollers turning against cam discs. The platen adjustment wedge was placed at the crown of the press instead of the usual position in the hub of the platen, to avoid being knocked - "for it is well known that pressmen are in the habit of throwing their wrenches or other tools down on the platen.”
