e temperature of about 200° F. After exposure to the air for a few days the surface is rubbed with cotton-wool or a fine rag, and variegated with a few streaks of metal powder or shell gold. Small objects may be dipped in the melted mixture and then exposed to the heat of the fire until thoroughly penetrated and evenly coated with it. The bronze letters and figures upon the bonds and paper currency of the United States — as, for instance, the faint attempt at a metallic ring, as Mr. Secretary Chase called it, on the old twenty-fivecent fractional currency — are made by printing in drying-oil, and applying the metal in fine dust to the damp surface. Bronz′ing—ma-chine. A machine for bronzing wall-papers or printed sheets. Those parts of the sheet which are to receive the bronze powder are first printed with letters or figures in ink or size. The machines vary in the special devices for distributing and removing superfluous powder. Bronzing-machine. In Fig. 941 th

e from the meridian of Greenwich Observatory was in 1679. The first magnetic chart was constructed by Dr. Halley, in 1701. It was limited to the Atlantic and Indian Oceans. Char-tom′e-ter. An instrument for measuring maps and charts. Chase. 1. (Printing.) A rectangular iron frame (a, Fig. 1255) which receives the matter from a galley, and in which it is arranged in columns or pages, and locked up in order for printing. Rules (if necessary) and furniture for spacing the pages are placed between the pages, and all locked firmly in the chase by wedges c c c, called quoins. Chase. The furniture, b b b, consists of slips of wood or metal, half an inch in thickness, and of any required length. Those at the head, foot, and side are called head-sticks, footsticks, side-sticks. Those between the pages are called gutters. Gutenberg used screws to lock up his form in the chase. Quoins came later. 2. (Ordnance.) a. The portion of a gun forward of the trunni

sses, etc. It is made by reducing to a degree of fineness, by machinery, coarse woolen cloths, rags, tags, old stockings, etc. Tilton and Ritson's flock-cutter. Flock-cut′ter. A machine for cutting fiber to a very short staple, called flock. In Barber's patent (1846) it consists of a cylinder with spiral knives rotating in contact with a concave having straight knives, the effect being a shear cut upon the fiber passing between the edges, which shave past each other. See also Chase, 1862; Pitts, 1856; Marble, 1872. The example (Fig. 2026) has a bed in which knives are arranged in parallel groups, of which one in each group is radial and the others of the group parallel therewith. The lower cutter H has a rotary motion and a vertical adjustment. The other cutter J has a self-adjusting movement, without rotation, but floating, as it were, on the surface of the runner.

A machine of the nature of a screw-stock to cut a thread on the end of a wrought-iron pipe. The figure shows the Chase machine fitted for handpow-er, motion being transmitted to the several parts by means of gearing; the pipe is shown projecting toward the left, and is held stationary by the adjustable jaws of the pipe-vise.

rge, each receiving its water from the same set of guides at the same time, and the water leaving each wheel independently. The two sets are cast together and to the same shaft (Fig. 6789). The Girard free turbine is so called from its having a pressure of air in the casing into which the wheel discharges, to allow the wheel to run in air and avoid the friction of tailwater. This pressure is, of course, in diminution of head, but it is supposed that the gain is greater than the loss. Chase inward and downward flow turbine. Schiele's inward-flow turbine (plan, showing scroll). The reversal of the action of the turbine driving it by steam-power in the direction contrary to its natural motion as a water-wheel forms the centrifugal or centripetal pump, according to whether the turbine be on the inward or the outward flow principle. See centrifugal pump; cen-Tripetal pump; propeller pump, Fig. 3977. Ruthven's English patent of 1849, for a hydraulic ship propeller, acting by
