PADDLE-WHEEL.

SPECIFICATION forming part of Letters Patent No. 350,395, dated October 5, 1886.

Application filed April 15, 1986.

To all whom it may concern:

Be it known that I, JAMES \V. REED, a citi zen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Paddle- WVhcels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being 11 ad to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to certain new and usefulimprovcmentsin paddle-wheels; anditconsists 1n the construction and combination of the parts, as will be hereinafter fully set forth,

and specifically pointed out in the claims.

In the accompanying drawings, which illustrate my invention, Figure l is a plan view of a paddle-wheel constructed in accordance with my improvement. Fig. 2 is a sectional view taken through the line x 00 of Fig. l; and Fig. 3 is a detail perspective view of an angle-plate which is secured to the radial arms, said angle-plates having also attached thereto the ends of the paddles.

In the accompanying drawings, A refers to the central shaft of the paddle-wheel, by means of which the same is secured to the vessehand power applied thereto for rotating the paddlewheel. This shaft has rigidly secured thereto by means of clamp-plates a a a seriesof five sets of radial arms, B B, said radial arms being indicated by the letters I). The arms 6 Z) are secured at their inner ends to the plates or disks a a, which are keyed or otherwise rigidly secured to the shaft A. The terminal portions of these arms which are indicated by the letter B, have attached thereto angleplates G, the edges of which are bent, as shown at c in Fig. 3. These angle or keystone shaped plates are rigidly secured by means of bolts (1 to the terminal portions of the arms b, and to the bent portion 0 thereof the paddles or boards D are secured by means of bolts 6. It will thus be noted that the paddles or boards D are secured to the arms I) at an angle therewith, and also at an angle with the main shaft A. The boards or paddles D extend diagonally Serial No. 198,904. (No model.)

from one set of arms to the next adjacent set, where they are secured to an angle-plate, G, which is attached to the arms B of said set, thus providing the wheel circumferentially with a series of diagonal paddles, each paddle attached to said angle-plates,extend therefrom to the spokes of the next set which are not occupied by the paddles of the outer sets. It will therefore be noted that the hubs E have twice the number of spokes as the hubs E and the central hub, F. The ends of the spokes may be secured to each other by the circumferential rim, when it is desired that they should brace each other.

It will be noted in a paddle-wheel constructed as hereinbefore described the paddles will enter the water successively, and when in a vertical position said paddles will present a horizontal straight line as well as vertical edges. By arranging the paddles as shown in the accompanying drawings 1 secure the largest amount possible of bearing-surface, and also cause the" water to be acted upon so as to create countercurrents whichbreak to a great extent the wavemot-ion usually produced by paddlewheels. Whatever wave-motion is produced by my improved paddle-wheel is directly and immediately astern and is sent in a converging direc tion with the course of the vessel. By so doing I am enabled to provide a paddle-wheel of great power, whirh creates but a small amount of Wave and does not interfere or produce counter-currents astern which interfere with the steering of the vessel, as the water is not displaced by the rudder.

I am aware that it has been proposed to construct paddle-wheelsas shown in Patent No. 177,461; but I do not claim such construction, as in said patent the paddles between the arms do not occupy opposing angles to each other, which is a special feature of my improvement,

to twist or turn the paddles so as to accom- :00 and with my improvement it is not necessary lnodate them to the angle of the supporting I so that the sides of the paddles will converge arms.

I claim- The combination, in a paddle-wheel adapted 5 to be applied at the stern of a vessel, of a central shaft having secured thereto a series of hubs, E, E, and F, the center hub, F, and the end hubs, E, having a less number of spokes than the intermediate hubs, E, tapered 1o angle-plates G, with converging flanges sccured t0 the ends of the spokes and paddles D, attached 1:0 the flanges of said angle-plates,

toward the central shaft, while the edges are parallel therewith, the parts being organized r 5 substantially as shown, and for the purpose set forth.

In testimony whereof I allix my signature in presence of two witnesses.
