A three-page article from the journal Engineering (21 August 1868) describing a portable steam-driven cotton baling press built by Appleby Brothers of London for cotton-growing districts, especially India. It explains the engine, drive and steering arrangements, and the screw and hydraulic ram pressing sequence that forms 100-ton bales in about seven minutes. It also covers the plan to drive extra presses and the benefits of compressed bales for rail transport and fire risk. The first page is a full-page pair of engineering elevation drawings.
