This model demonstrates the principle of the endless screw, a component used in many machines. A wooded tripod carries a profiled support holding a horizontal endless screw fitted with a handle. The screw meshes at right angles with a cogwheel equipped with a drum. A cord holding a brass weight is wound around the drum. Provenance: Lorraine collections.
