For Philips & Lee. Cotton mill [?], Salford, Lancashire. Engine ZE was called "Tantalus", and one of the other engines was named "Pollux", but which one is unknown. These three engines were ordered at the same time. Engine ZF was erected near the engine called "Pluto" [see Portfolio 5/242b]. Engines ZH and ZE, "Tantalus", were connected together. Engine ZE was of an usual arrangement which Boulton Watt & Co. referred to as "wiggle waggle". The inner end of the beam was connected directly to the piston rod, and the outer end was mounted on the engine framing. The connecting rod was connected to the beam between the beam's centre and inner end, and worked the crank shaft which was mounted in the centre of the base frame. Boulton Watt & Co. only made four engines employing this arrangement: an earlier one for Philips & Lee in 1807 [see Portfolio 5/844a]; one for Thomas Lowe in 1807 [see Portfolio 5/845]; one for Bally Ellen & Steart in 1808 [see Portfolio 5/846]; and this one.
