rojections of each of which fit into the depressions of the other. These are arranged in a suitably shaped box C, and driven by pitmen so arranged that por tions of the periphery of each blower shall be constantly in close proximity, while the two ends or wings of each move in proximity to the curved sides of the box. The rotation of the two blowers in opposite directions draws the air through an opening in one side of the box, and forcibly discharges it through a blast-pipe at the other. Root's blower, b, is similar in principle to the foregoing; the projections of the cams are, however, rounded off so as to form circular arcs, while the depth of the depressions is decreased, causing a longer lap on the abutting surfaces, so as to provide against the escape of air in the wrong direction. In c a series of bellows, provided with suitable valves, are radially arranged around a tube surrounding the axis of a wheel. A heavy block moving in guides descends by gravity on approaching

between the valve and piston is drawn forward to the discharge opening, which is unstopped by the motion of the inner sleeve. Baker's measuring-faucet. Baker's measuring faucet is on the principle of the rotary pump. An eccentric in the chamber is revolved by a crank, and the sliding piston ejects at each revolution the known contents of the cylinder. A register on top keeps tally of the revolutions. In another variety of this type, two cylinders work together, in the manner of Root's blower, projections on one entering cavities in the other, and each being packed against its own portion of the twin cylinder inclosing the two. Measuring-funnel. Meas′ur-ing-fun′nel. One having graduations to indicate quantity at different degrees of fullness.

An instrument for estimating the force of an electric current by means of an oscillating needle which traverses against a graduated arc of 90°. Quad′rant Steam–en′gine. This is a modification of the oscillating-piston engine. Root's double-quadrant engine has a pair of oscillating single-acting pistons connected by links to one crank. The steam is admitted to act on the outer sides of the pistons alternately by means of one in- duction-valve, and is exhausted through the space between the pistons. The piston and crank connection is such that the steam acts on each piston during about two thirds of the revolution of the crank, and thus there are no deadpoints. Quadrant-engine. Quad′rat. 1. A ma

lings are worked spaces connecting rooms, and the cutting of the thirlings changes a wall to a row of pillars. Room and space staff. （Shipbuilding.) A long measuring-rod used in spacing and regulating the distances apart of a ship's frames. Room and space is the distance between the stations of the timber frames which constitute the ribs. It varies from 2 feet 6 inches to 3 feet 9 inches. Room is the rib; space the distance apart. Room-pa′per. Wall-paper. Paper-hangings. Root. （Hydraulic Engineering.)

The machine a, used in Britain, has two widely fluted rollers placed under a hopper and turned by two hand-cranks. The pomace falls into a chute, which delivers it into a tub. The object is to obtain the root in such a shape as to be more digestible and less

acts expansively in giving the upward stroke. See also Whitham's United States patent, September 4, 1841, using live steam on annular head, and expanding same steam on circular head See also Henderson's patent. April 5, 1870, No. 101, 617. In Root's engine, August 7, 1866, No. 56,993, the piston is attached to an elongated trunk extending through both heads of the cylinder. The pitman passing through the trunk is attached to the end thereof most remote from the crank-shaft, and this end works in guides secured to the cylinder-head Root's trunk-engine. The double-trunk engines constructed by John Penn and Sons, Greenwich, England, for the English iron-clad Hercules, are said to be the largest pair of screw engines ever built. There are two cylinders, each 127 inches in diameter, by 4 feet 6 inches length of stroke of piston; the diameter of the trunks is 47 inches, whose area, being deducted, gives the pistons an effective diameter of 118 inches.
