1874 · Clockwork Vault Lock · Werk 724 von 1.871

A time lock of 1874 mounted on the inner face of the open steel door of a safe in a small-town bank in the American Midwest, a flat, nearly square metal case seventeen centimetres high, twenty wide and seven deep with rounded corners, its whole cover bright fire-gilt gold with an irregular crystalline hammered texture, in the cover a large flat glazed window, wide across the top and narrowing in a curve toward the bottom, behind the glass side by side two small round black rings around open spoked brass wheels, small, at a slant, polished steel bolt bars on the door, a hand in a dark sleeve holding a small winding key at the case, warm kerosene lamplight from the right.
Was die Quellen offenlassen: Die Firmengeschichte nennt für 1872 keine Patentnummer. Die auf my-time-machines.net wiedergegebenen Patentdaten 1875 bis 1877 stehen auf Riegelplatten späterer Schlösser und widersprechen den Jahren 1872 und 1874 nicht.
