AN IMPORTANT MODEL OF RICHARD TREVITHICK'S ILL-FATED GATESHEAD LOCOMOTIVE OF 1805, SUCCESSOR TO THE PEN-Y-DARREN LOCOMOTIVE OF 1804

AN IMPORTANT MODEL OF RICHARD TREVITHICK'S ILL-FATED GATESHEAD LOCOMOTIVE OF 1805, SUCCESSOR TO THE PEN-Y-DARREN LOCOMOTIVE OF 1804,
similar to the Pen-y-Darren locomotive, it was built with the engine position reversed, such that the flywheel was mounted at the chimney end. It was ordered by Christopher Blackett, owner of Wylam Colliery who feared for his wooden truck and refused to pay. It was subsequently turned into a cupola blowing engine. The horizontal boiler is flanged at the fire-hole door end and the back-head plate supports the chimney and main crankshaft bearing brackets. The cylinder is set horizontally into the boiler and has integrally cast plug valve gear driven via a plug rod and lever mounted on the cruciform piston rod cross-head. The cross-head runs on horizontal bar guides supported on wrought iron brackets secured to the chassis, and drives twin cotter big and little ends connecting rods set to avoid the flywheel and intermediary drive spur gear. The flywheel incorporates a counter-balance weight and is mounted on a square and faceted crankshaft with a slip plate driven gearwheel engaging the main drive spur wheel and individual gearwheels bolted to the outside of the cast iron spoked wheels, 10in (250cm) high x 15in (38cm) wide
