odgers's anchor. Rodgers's anchor has a shank with a wooden core, for giving more surface, and consequent strength for a given weight of metal. Williams's anchor, patented March 16, 1858. This anchor has three flukes hinged to a block at the lower end of the shank, and so set that two of them may penetrate the ground at the same time, while the third falls down upon the shank to prevent the cable from being fouled. The flukes are set at 120° apart and hinged in a separate block. Williams's anchor. Morgan's anchor, patented June 21, 1864. The arms are separately pivoted near the end of the shank, and are connected by a curved bar passing through a hole in the shank. When one fluke has hold of the ground its arm rests against and is supported by the crown-piece, while the other arm falls down upon the shank, obviating the danger of fouling and by means of the curved bar assisting the first arm to bear the strain. Morgan's anchor. Marshall's anchor. Marshall'S

washers, feltrollers, etc. Felt-carpet. A carpet whose fibers are not spun or woven, but are associated by the felting process. Felt′ed cloth. (Fabric.) Cloth made by felting, without spinning or weaving, was patented in England by Williams, in February, 1850. Felt-grain. (Wood-working.) The grain of wood whose direction is from the pith to the bark; the direction of the medullary rays in oak and some other timber. Felt′ing-ma-chine′. Felting-machines are of various kf the rollers, the hairs are displayed and thus laid over a straight edge. The knives are fixed radially to a rotating disk, and shear past the straight-edge, severing the hairs with nearness to the skin determined by the set of the machine. Williams, 1832, has a frame with a series of parallel knife-edges presented upwardly. Over them is a block carrying an oblique knife which makes a shear cut upon the fixed knives in succession. Flint's fur-cutting knife, 1837, has an edge on one j
sharp knife by a skilled workman, to remove whatever hair may yet remain in the fur. It is then returned to the kettle for a second sizing, to farther close up and strengthen the felt. After the farther operations of being stiffened, cleaned, blocked, colored, shaped, and pounced, the body is ready for the finishing process. The great improvement of the perforated exhausted cone, with its attendant slotted blowing cylinder, is due to H. A. Wells, by whom it was patented April 25, 1846. Williams, in England, had previously employed a partially exhausted cone in connection with a carding-machine for making hat-bodies from tow or waste silk. See blowing-machine, p. 307. In this country, fur, mixed with a little SeaIsland cotton, is generally employed. The forming and sizing of the body are done in a way precisely similar to that of felt hats, hat a much less quantity of stock, from 1 to 1 1/4 ounces, is used. After sizing, it is dipped into a solution of shellac and alcohol,
was built in 1831. She was 70 feet long, 13 feet beam, and 6 1/2 feet deep. When launched she drew 9 inches of water; when equipped she drew 40 inches. She was navigated to the scene of her exploits, twice ascended the river, and her ribs upon the strand of Clarence Cove were visible but a few years since, and may yet remain. Her engines were 16 horse-power. Her weight, without engine, 33,600 pounds. The Garry Owen was the first iron vessel with water-tight bulkheads; suggested by C. W. Williams. See bulkhead. Iron vessels for America, Ireland, France, India, and China were built in Scotland and on the Mersey, 1833-39. The iron steam-vessels Nemesis and Phlegethon were used in the villainous Opium War of 1842. They were not the last vessels built on the Clyde for piratical expeditions. The Ironsides was the first iron sailing vessel of any magnitude employed for sea voyages. The Great Britain, built at Liverpool, was the boldest effort in iron shipbuilding in her

In 1849. Jonathan Haines, of Illinois, invented the header, which is the principal machine on the Pacific coast. 1849. Purviance made the platform removable, to convert the reaper into a mower. 1849. Platt's self-acting rake sweeping over quadrantal platform. Same feature in Palmer and Williams's and in Seymour's, 1851. 1850. Adkins's cutter-bar on hinged frame. 1850. Knowles and Bevington's side dropper. 1850. Heath's binder, with a reciprocating rake beneath the platform. 1851. Watson's automatic binder. 1851. Miller's backwardly reciprocating rake. 1851. Allen geared the operative parts from both wheels, to distribute the driving-power. 1852. Atkins had a rake rigged on a vertical post. It had a jointed arm which swept across the curved platform and gather

in correspondence with the pattern at each end of the pack. In making lenses, templets of sheet-brass are first made corresponding to the curves of the lenses. These templets are used in making the shells and runners, between which the lenses are ground to shape. Perforated templets are used by boiler-makers and others to lay out the holes for punching. In order to allow one section of pipe to slip into another, the holes around the plate are not punched in rectangular patterns. Williams's adjustable templet has movable perforated side bars, combined with T-shaped heads upon the central bar; also adjustable and perforated slides combined with each other and with the central bar. Adjustable templet. 2. (Shipbuilding.) a. A mold of a certain figure to test or direct the conformation of a timber or other object. b. A perforated piece or strip by which a line of rivet-holes is marked on a plate to be punched. c. One of the wedges in a building-block. 3. (Buil
y on a vertical axis. The axis carries an endless screw, which, by means of interposed gearing, rotates a hand or hands moving around one or several dials, or it is caused, by proper mechanism, to leave a record on an endless strip of paper. Williams's wind-gage, or air-meter, consists of a rotary vane a, surrounded by a cylindrical casing; the axis of the vanewheel carries an endless screw, which, by suitable gearing, actuates the pointers on a series of dials; the gearing may be so adjuste,626.McNair, 1869. 94,704.Blanchard, 1869. 94,869.Clark, 1869. 95,473.Heinnemann, 1869. 95,474.Heinnemann, 1869. 95,583.Hayford et al., 1869. 99,186.Haupt, 1870. 100,380.Day, 1870. 100,608.De Smedt, 1870. 101,012.Hayford, 1870. 101,691.Williams, 1870. 102,725.Stevens, 1870. 103,105.Van Camp et al., 1870. 104,916.Tripler, 1870. 104,917.Tripler, 1870. 4,837.Tripler (reissued), 1872. 4,838.Tripler (reissued), 1872. 106,625Sheldon, 1870. 107,620.Nickerson, 1870. 107,854.Beach, 187
