uble or single tier ambulance. Each couch of the lower tier is divided longitudinally and hinged. It may lie flat upon the floor, while the upper tier is occupied by other patients; or it may be bent so as to form a seat and support, while the stretchers of the upper tier are placed on edge against the carriage sides and form backs for the seats. The sides are separately adjustable. The two-wheeled ambulances are spring carts with provision for recumbent or sitting patients. Rucker, Allen, and Smith's ambulance. Hayward, May 16, 1865. The stretchers may be adjusted for recumbent or sitting patients, the legs operating to support them in either capacity when the stretchers rest on the ground. The packsaddle has wedge-shaped sockets to receive corresponding wedge-shaped blocks on the legs of the stretchers. Sirs, 1863, Wilkins, 1864, Slatter, 1865, and others have patented improvements which might be cited would room permit. Hayward's ambulance. This description

p when the cam passes them. In Stevens's cut-off, 1841 (Fig. 1568), a rotary shaft a is placed between the upper and lower steam-chests b b, and has two lifters c d placed on opposite sides of its center, which alternately raise and depress the valves by the toes e on the rock-shaft. To adjust the toes, a slot and pin are provided in the rock-shaft arm. To cut off shorter, the toes must be dropped, the pin raised, and the eccentric set ahead. To cut off longer, reverse the operation. Allen's Cutt-off. Allen and wells's cut-off, 1853 (Fig. 1569). Upon the rock-shaft M are arranged the loose steam-toes B B, with pawls E E′ pivoted to their outer ends, which are raised by rollers a a on a cross-arm G of the rock-shaft arm F, and when they clear the rollers they drop inward, thus opening and closing the valves. To adjust them, two arms H H are provided with a right and left hand screw. The arms, having motion nearly coincident with the piston, start downwards at the same tim

ooped shank. Harp′si-chord. （Music.) An obsolete stringed instrument resembling a harp laid prostrate, the strings being played by quills operated by keys like those of a piano-forte. Harpoon-rocket. The harpsichord is believed to have been first made by Hans Rucken, in Germany, about 1510. Used in public festivals in Italy, 1522. Improved by Vincentino, 1555. Vertical form invented by Rigoli of Florence, 1620. Pepys, in his Diary (1661), speaks of the harpsichon at Captain Allen's house, where he saw his dear Mrs. Rebecca. The spinet was a similar instrument with one wire for each note, and, like the harpsichord, was played with quills on jacks, operated by keys. The clavicytherium may be considered the original of the whole train of stringed instruments whose strings were mechanically vibrated. See pianoforte. The harpsichord introduced two strings to a note, and preceded the piano, from which it differed specially in the mode of vibrating the string

h drive against the springs and expand the circumferential ring. g is Blake's piston, 1871, a part of which is shown with the cover removed. It has screws which force a body of soft vulcanite or metallic springs against the outer rings of the piston. The screws are turned by bars. h is the Huss 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, 186
