1. (Mining.) A kind of bucket (a, Fig. 5136) employed in narrow or inclined shafts where the hoisting-device has to be confined between guides. It is held to the guides by friction-rollers and flanges, which bear against them, and is provided with a hinged door for discharging material. b. is a water-bucket, used in mines where the quantity to be raised is small, or previous to putting down a pump. On striking the water, the valve e rises; it falls by the weight of the superincumbent water when the downward motion is stopped. c is a rock-bucket, frequently used in vertical shafts, and d a kibble. The latter is adapted for use in shafts that are irregular, or not perfectly vertical. Each has a becket and ring at the bottom, by which it is inverted for dumping. One ordinary form, used in raising ore to the surface, is a square tube of boiler-iron, having a capacity of about 20 bushels. It has a lip to direct the stuff in discharging.
2. (Sugar-making.) A charge of sirup in the pans.
3. (Fiber.) A wicker basket mounted on wheels and employed to convey cops, etc., about a factory.
