s piston, 1871. combining wedges and screws. By turning the screws, the radial bars projecting from the central boss are forced against the wedges on the inside of the expanding ring. i is Allen's piston, 1873. It has wedges and springs, and a rack to hold it to its set. The portion of the wedge-plate at z is broken away to expose the rod and the spring which bears against the segment which distends the packing-ring. The rotation of the wedge-plate acts upon each of the three. j is Carey's piston, 1873, which has an axial screw and a conical nut, the latter pushing against the stems of the followers to force outwardly the peripheral piston-ring. k k′ are Adams's piston, 1868, in which the piston-rings are wedge-shaped at their overlapping portions, and are driven outwardly by the lateral pressure of a wedge actuated by springs on the face of the piston. l is Buchanan's piston, 1865, in which the piston-rings are expanded by steam admitted behind them, through aperture
of revolutions made. See speed-gage; speed-recorder. 2. (Nautical.) A log consisting of a spiral vane turned by the passing water, and registering its revolutions. See velocimeter; log. Speed-meas′ur-er. An instrument invented by Mr. Carey, for meas- uring the number of revolutions made by the wheel of a carriage. It is secured by straps to one of the spokes near the hub, and has clock-work mechanism for registering the number of revolutions. See odometer; speed-gage; speed-reing. Stereotype shooting-board. About 1779, Van der Mey's process was revived by Dr Alex Tilloch of Glasgow, but it still does not seem to have come into general use, as we hear little of it until it was taken up by the French printers. Carey's method of stereotyping, France, 1793, was as follows: The form was attached to a block suspended face downward from a beam, and was suddenly allowed to fall upon a surface of hot lead, just in the act of solidifying. The matrix thus obtained w
