[Because this engine underwent so many changes during the planning, and because the drawings are so numerous, they have been arranged slightly differently to the other portfolios. Drawings of the engine house and engine are listed first, chronologically, then the component drawings, again chronologically. All the drawings are uncoloured reverse copies and bear letter codes unless otherwise noted.]

Original Portfolio or 'Book' No. 393.
For the Salford Twist Co. Flax mill [?], Salford. The firm later became Philips Wood & Lee, and then Philips & Lee. George Lee ordered this engine to power the firm's new mill, which was located alongside the old one and may have been for flax spinning, in 1800. The initial plan was for a 60 or 62 horse engine, but the entry in Engine Order Book No. 3 dated 20 Aug. 1800 was for a 70 horse engine. The order was altered to a 100 horse power engine with a 48 inch cylinder circa Feb. 1801. The firm appear to have called this engine "Ixion". This engine was omitted from the Catalogue of Old Engines.

Published references: Dickinson & Jenkins, p. 172, 189, 203. Dickinson & Jenkins refer to the drawings of the eccentric circles and the beam, but ascribe them to the 1799 30 horse power engine, when in fact they were for the 100 horse power engine. |
