AN EARLY, SMALL, FULL-SIZED TABLE ENGINE,

circa 1810,

This detailed engine, of 'Gothic' style, has a single cylinder of 2.25" bore x 4.5" stroke, has two D-section annular ribs and the cylinder cover incorporates a waisted gland retained by eye-bolts with square nuts and finial ends. The crosshead is retained on the piston rod by an acorn knop, bar-type guides with threaded bottoms secured into the cylinder flange using filed flats, then flanged hexagonal nuts which both retain the cover and give strength to the guidebars

The valve chest includes a plug-type governor valve and a repetition of both gland and cross-head. The main and valve connecting rods are flat section and the valve gear motion is carried on a square transverse shaft supported by decorative brackets; it is powered by an adjustable eccentric push-rod lever. The crankshaft sits within the 'Gothic' frame with the bearings supported on bridges cast- in-one with the end castings. It has three governor pulley diameters, is square in section and drives an elegant square section flywheel.

The engine speed is regulated by a 'Watt style' governor with brass balls, top support from cylinder cover, upward looking bevel gear with onion base and adjustable needle bearing, all driven by a horizontal shaft with three different diameter pulleys to match those on the crankshaft. The governor actuating rod is pivoted from the bed and the vertical rod and plug cock lever are missing.

The bed is supported on decorative cast iron columns with square nuts. 31 ins (78cm) high x 20 1/2 ins (52cm) long
