Bush
1911 Encyclopedia Britannica
or (I) (A word common to many European languages, meaning "a wood," cf. the Ger. Busch, Fr. bois, Ital. bosco, and the med. Lat. boscus), a shrub or group of shrubs, especially of those plants whose branches grow low and thick. Collectively "the bush" is used in British colonies, particularly in Australasia and South Africa, for the tract of country covered with brushwood not yet cleared for cultivation. From the custom of hanging a bush as a sign outside a tavern comes the proverb "Good wine needs no bush." (2) (From a Teutonic word meaning "a box," cf. the Ger. Rad-biichse, a wheel box, and the termination of "blunderbuss" and "arquebus"; the derivation from the Fr. bouche, a mouth, is not correct), a lining frequently inserted in the bearings of machinery. When a shaft and the bearing in which it rotates are made of the same metal, the two surfaces are in certain cases apt to "seize" and abrade each other. To prevent this, bushes of some dissimilar metal are employed; thus a shaft of mild steel or wrought iron may be made to run in hard cast steel, cast iron, bronze or Babbitt metal. The last, having a low melting point, may be cast about the shaft for which it is to form a bearing.
