UNITED STATES PATENT OEEIcE.

MICHL. H. COLLINS AND WM. H. HOLLAND, OF CHELSEA, MASSACHUSETTS.

IMPROVED PADDLE-WHEEL.

Specification forming part of Letters Patent No. 58,603, dated October 9, 1866.

To all whom it may concern:

Be it known that we, MICHAEL H. COLLINS and NVILLIAM H. HOLLAND, of Chelsea, in the county oi' Suffolk and State of Massachusetts, have made a new and useful invention having reference to Paddle-Wheels for Steam- Vessels; and we do herebyT declare the same to be fully described in the following specification and represented in the accompanying drawings, ot which- Figure 1 is a top view, Fig. 2 a side elevation, Fig. 3 a longitudinal section, and Eig. t a transverse section, of a paddle-wheel provided with our invention.

Thehub A ofthe wheel consists of three circular plates, a b c, fixed at equal distances apart on a tube, d, and kept apart by two collars, e e, arranged between them and on and around such tube.

From each ot' such plates a b c a series of forked arms, h h., extends, the arms of each series radiating' from the axis of the hub, and being riveted to their plates a, b, or c. Each series of such arms is also riveted to one of a series of platc-rings,t' 7c Z, arranged concentrically with the hub.

Around each ofthe rings il is another such ring, m, which is arranged at a distance from and in the same plane with the ring which it circumscribes. Each two rings, i m, m l, are joined by a series of radial connection-plates, a a, arranged at equal distances apart, the junction of the plates and rings being by means of rivets. Through each of the plates a we form an elongated hole, o, to facilitate the escape of water from the space between the two obtuse angular paddles connected to such plate a.

We fasten by rivets to each two opposite connection-plates two obtuse-angular platepaddles, r r, which we arrange between the two rings m m, in manner as shown in the drawings. Each of such paddles consists of a rectangular plate of metal bent at its middle to an obtuse angle. The plates ot' each pair have their angles or bends arranged in opposite directions with respect to each other, in manner as shown in the figures. Furthermore, each paddle of each pair of paddles is connected at its bend to the next paddle to it by means of a junction-plate, p, which is riveted to the two paddles, and also to the central ring, K, from which 1t projects radially. A hole, q, is made through each of the plates p, to enable the water to tlow through the plate while the wheel may be in operation.

Each paddle at its two ends is to lap on its supporting-plates a a, in order thatit may be riveted to them. So with respect to each ofthe connections p, it is to have flanges by which it may be connected by rivets to the next adjacent paddles and to the ring k.

A paddle-wheel constructed in manner as above described may be made of wrought plate-iron, and be of great strength and very light, and will be exceedingly eflicient as a motor or propeller.

Vhat we claim as our invention in the said wheel is as follows:

1. The arrangement and combination of its obtuse-angular plates or paddles r r with the three series of end and niiddle connections, a p u, and the three wheels, composed of the rings t' 7c l and the three series of spokes, applied together and to a hub as described.

2. The combination and arrangement of the external rings, m on, with the paddles r r, the

three series of connections n 11 a, and the three wheels, composed of the three rings t' k Z and three series of spokes, applied together and to a hub as described.
