The Roberts Engine66 viewsThe Roberts engine at Bancroft is a two cylinder horizontal cross-compound engine. ‘Compound’ means that the steam first passes through the high pressure cylinder (James) and then the low pressure cylinder (Mary Jane) to extract as much energy from the steam as possible. Efficiency is further improved by a condenser in the cellar which condenses the exhaust steam creating a vacuum which increases the effective pressure across the low pressure cylinder.
