UNITED STATES PATENT OEEICEo JOSEPH F. BREUX, OF HARDWIOK, VERMONT.

FEATHERING PADDLEiWHEEL.

SPECIFICATION forming part of Letters Patent No. 242,874, dated June 14, 1881.

Application filed March 2, 188]. (Model.)

To all whom it may concern:

Be it known that I, JosEPH F. BREUx, of Hardwick, in the county of Caledonia and State of Vermont, have invented a new and usefullmprovement in Paddle-Wheels; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part oi' this specification, in which- Figure I is a vertical section through the wheel at right angles toits axis. Fig. 2 is an edge view of a portion ot' its periphery; and Fig. 3 is a detail view, in perspective, ot' one of the paddles. Y

My invention is designed to provide an improved form of feathering paddle-wheels for steam-vessels, whereby the full power of the paddle against the water is utilized for the effective part of its movement, while the carryin g of dead water is avoided by the paddles as they pass from their lowest position to the surface in the rear.

The general principle upon which I coustruet my wheel is to loosely hang the paddles between two rims of the wheel, so that they will afford a full resistance to the water when pulling on a horizontal line, but leave the water edgewise when they commence to rise therefrom. This general principle I do not claim as new. My invention, however, consists in the peculiar arrangement of parts acting on said principle, in which the paddles are provided with triangular end frames or arms which are pivoted at one side of the paddles, so that the pivots of one paddle are near the face of the next, and which paddles co-operate with lugs or stop-proj ections of the side frames or spokes ofthe wheel, so that when the paddles are pulling they rest within the periphery of the wheel against said lugs in radial position, and when they reach that point otl the wheel where they would commence to rise from the Water they drop down outside the periphery of the wheel vand rise through the water edgewise, so that they carry no dead water.

In the drawings, A represents the shaft of the wheel 5 B B, the side frames, composed of the rim and spokes, made in any approved way 5 and C represents the paddles. Ihe rims ofthe wheel are connected by rods D, which hold said rims a distance apart a little greater than the length of the paddles, so that the latter can swing freely between the same. To the ends of these paddles are attached triangular end pieces or arms, a, that are bolted tothe paddles and project therefrom at right angles, and are pivoted or hinged upon the"rods D at their outer or 'convergent ends. At the point where the arms a are hung to these rods D said arms are re-enforced by cap-pieces b. The portions of these arms next to the center ot' the wheel are `also extended past the paddles, and when the paddle is under a working strain these extensions c rest against lugs or stops d on the inner sides of the spokes ofthe wheel-frame.

W'hen the wheel is at work in the water and revolving in the direction ot' the arrow, the

face :v of the paddle, or the one opposite the A frame or arms a, is the working-face, and the pressure ofthe water thereon throws the paddles up inside of the periphery of the wheel, so that they occupy a radial position, with the extensions c resting against the stops d on the side of the wheel-frames. This is the position ot' all of the paddles which are capable ot' exerting a beneficial pulling strain. After the paddles pass to the rear, however, ot' the central vertical line ofthe wheel and the paddles commence to rise, they drop down upon their f pivot-rods D, outside of the periphery of the wheel, bringing the paddle-blades into a more nearly vertical plane, so that they rise edgewise from the water. When the paddles thus drop down they are supported by the next pivot-rod in the rea-r.

Having thus described my invention, what I claim is- A paddle-wheel consisting of the combination of side frames or rims connected by rods D, and having stops d on their inner sides, and the paddle C, having right-an gular projecting arms or frames a, which are pivoted or hung upon the rods D, with the pivot of one paddle arranged near the face of the next,whereby the paddles are made to occupy a radial position when pulling and drop down to be lifted through the water ed gewise, as described, when they cease to have a useful effect.
