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.
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.

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.
