into the box-screen I, which, being shaken by suitable mechanism, separates the still remaining lighter portions of the hulls that pass the wire screen, carrying these portions out over the apron J, while the cleaned and hulled seed passes out through the chute K. Cotton-seed hulling-machine. Cot′ton-seed mill. One for grinding the seed of cotton, either for manure or for obtaining from the meal the oil, either by pressure or the more usual mode of treatment by bisulphide of carbon (Sim's process) or hydrocarbon. Cotton-seed planter. Cot′ton-seed Plant′er. One in which the feedmotions are positive, as the seed adheres by the interlacing of its fibers, and requires to be torn apart and driven down the chute to the ground. In Fig. 1491, the adjustable teeth are arranged within a case in a hopper, and are operated by gearing in connection with the driving-wheel, and regulated by cams secured to the case, whereby the cotton-seed is projected down the tube.

the air from pump e is led through the steam-jacketed chamber m to enable it to volatilize the bisulphide of carbon in a. g is a gas-holder to hold any superfluous gas, to keep the capacity adjusted to the varying volume of the contents. The boiling-point of the bisulphide of carbon is 118° Fah. The process is adapted to dissolving the oils contained in the strippings of machine-cards in factories, and saving the waste from the axles of car-boxes, the journal-boxes of machinery. See also Sim's and Hutchinson's processes and machines, patented 1869, 1870, 1871. These are also particularly intended for extracting fusel-oil from grain. Oil-fil′ter. Robinson's oil-filter acts by the upward pressure of a column of water below the oil. The operation is as follows: — Robinson's oil-filter. Oil-gas apparatus. The butt g of oil being placed on a stillion, communication is made with its lower portion by means of a pipe a leading from a cistern of water n. As the water flo

ng through an eye-bolt in the block a, allowing considerable freedom of motion; the block is secured to a lathe or work-bench by screw attachment b; c is a piece of wood being pared. 2. One used for peeling fruit, having a guard to regulate the depth of cut. 3. A farrier's hoof-paring tool. 4. (Surgical.) A knife used in removing the cuticle or ragged edges of parts which are to be placed in apposition that they may grow together. The examples are respectively, — Upper one, Sim's knife for paring edges in the operation of vesico-vaginal-fistula. Below it, curved knife for same operation and that of cleft palate. Paring-knife. Par′ing-ma-chine′. A key-grooving machine. Par′ing-plow. （Husbandry.) A plow for cutting sods or turfs from the surface of the ground. A sod-plow. Paring-scis′sors. （Surgical.)

A gold-colored alloy of copper and zinc. See Semilor; alloy. Sim′ple. （Weaving.) a. A draw-loom employed in fancy weaving. b. A cord dependent from the tail of a harness cord in a draw-loom, having at its end a bob, Sim′ple. （Weaving.) a. A draw-loom employed in fancy weaving. b. A cord dependent from the tail of a harness cord in a draw-loom, having at its end a bob, by which it is pulled to work a certain portion of the harness. Sinch (Spanish cincho, a girth). (Harness.) A strap whereby the loop on the end of the girth of a Spanish saddle is laced to the se and nozzle. An invention for this purpose was introduced into Glasgow, in April, 1868, by Mr. Sim. On one side of the roadway, pipes were laid next the pavement, and con nected with the water-er-stock the results. Wesselholft, October 6, 1868. Extract of malt for dietetic purposes.
