Compound Spirits
rectified spirits to which has been added one or more flavoring ingredients. They are called also compounds. The chief compounds are gin, British rum, British brandy, and some grades of American whisky, cordials and liquors. a COMPOUND STEAM-ENGINE, form of steam-engine originally patented The by Hornblower in 1781, in which steam at a relatively greater pressure was allowed to expand in a small cylinder, and then, escaping into a larger cylinder, to expand itself against a larger piston. expar Compound engines are of two classes, which may be called compound and independent compound engines. former are those in which the cylinders are near each other, and the pistons commence their respective strokes simultaneously or nearly so, the steam expanding from one cylinder direct to the other through as small a passage as convenient. To this class belong most land engines, and the compound marine with cranks at about 130°.
