IMPRovnMENT -IN Paloma-WHEELS.

To all whom it may concerm e VBe it known that I, Lninnnn W'. WRIGHT, of Brooklyn, inthe 'county of Kings and Stateof New York, have inventedfa certain new and useful Im-f provement, in'Pjaddle-Wheels; and the following is hereby declaredto be afull and correct description of the saidinvention. j

The objects of 4this invention are to prevent coneussiou as the buckets ofjthe wheel strike the water, to avoid the swell or sidevvise wave from the paddlewheel, and to lessen the lifting of water as the`buck ets leave the same. f

'I accomplish these objects by placing the buckets diagonally (at about forty-live degrees) to the axis oi' the shaft, and arranging 'them in ranges or `rows around the wheel, the buckets of one range standing at anlopposite inclination to those of the next range, and I placethe buckets of one range' intermediate to those of the adjoining ranges.

Figure 1 represents ,an elevation 'of my improved paddle-wheel; y

Figure 2 is aplan of the same;

Figure 3 is an elevation; and i .Figure 4, a plan of one of the buckets detached.

ais the shaft of the paddle-wheel; b-b, the arms connected tothe shait a and to the rings d, in any suitable manner, and to these arms the buckets c vare attached, the whole composingthe paddle-wheel.

These buckets are to be` arranged in two, four, or, more ranges or rows, running around the wheel, each range standing at an opposite inclination, and each bucket in a position diagonal'to the axis of the shaft, and intermediate to the buckets of the adjoining ranges.

I prefer that the diagonal position of the buckets should be about forty-five degrees to the vertical .planes of the rims' or arms to which they are attached. i

By reference to fig. 2, it will be seen that by plac#l ing the buckets in the diagonal position above mentioned, and by making the; inclination of each range of buckets run in an opposite direction, each of said i ranges forms a section of a many-threaded screw, one

projecting beyond the edges'of the rims of the wheel, and each bucket coming to a sharp point. Instead of .being so formed they may be made' with a circular or straight outer edge,"as shown at fg, by dotted lines, fig. 1, or, if desired, the buckets might be iiush withv the rims of the wheel.

A paddle-wheel made in the manner above set forth possesses many advantages over the wheels heretofore used. The diagonalposition of the buckets prevents concussion as they enter the water, and gives to each of said buckets the properties of a section of a ,se`rew so that each bucket commences to take a hold upon the water at the point of entering, and continues, during its entire passage through the water, to act against the water, and, during the latter part of its passage,

very little or no water is lifted,'and,astl`ie, lateral.

tendency of the water, as shown by the buckets of" one range, is counteracted bythe next range of blickets, the water is passed 'directly to the rear, and the heavy side swell caused by the ordinary paddlefwheel is avoided, and the wheel acts vequally well, or nearly so, when going in' eitherl direction, and the' wheel may be immersed to a greater extent than the paddle- Wheels heretoforemade ,without injuriously affecting the same, thereby'increasing Athe hold of the wheel on the water, and the paddles are not `liable to be injured by the waves. j

I do not claim a paddle-wheel in which the buckets in one range stand at alternate inclinations between Vthe rings, and are so placed to `the adjacent range as to forma zigzag passage. ,l

In my wheel all the buckets of one range stand inclined in one direction, and one bucket is separate and distinct from the next in the range, so that the buckets of one range are like-the many threads ofja rightfhanded screw, and the buckets of the next range are like the many threads of a left-handed screw, and, these are arranged so that the edges of the buckets of one range are opposite the spaces between the buckets of the next range.V A

What I claim as my invention is- 1. A paddle-wheel made of ranges of buckets, ar-

ranned as alternate right and left-hand screw-thread l sections, and positioned in .the manner'and `for the purposes set forth.

2. A paddle-wheel in which the buckets are arranged as aforesaid, and the outer edges of thebuck ets project, in the-- manner and for the purposes set forth. j t i Signed this 28th day of December, A. D. 1869.
