Description
i i l UNITED STATES PATENT OEEIQEO WILLIAM H, HOLLAND, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO HIM- SELF AND WILLIAM GOODMAN, OF SAME PLAGE.
IMPROVED PADDLE-WHEEL.
Specification forming part of Letters Patent No. 55,770, dated June 19, 1866.
To all 'whom fit may concern.-
Beit known that I, WILLIAM I-I. HOLLAND, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Paddle -Wheels for Steam-Vessels; and I do hereby declare'the same to be fully described in the following specication and represented in the acco1npa nying drawings, of which- Figure l is a t'op View, Fig. 2 a side elevation, and Fig. 3 a longitudinal section, of a paddle-wheel constructed in accordance with my invention.
In the said drawings, A A are two thin wheels applied to a horizontal shaft, B, and arranged with respect to it and cach other as represented. Between these two wheels, and applied to them at their rims and spokes, is a series of curved oats or buckets, C C C C. Each of such oats consists of a plate of metal bent at its middle into a forni approximating to aparabola. At or nearits two ends each ofthe floats is fastened or riveted to the two wheels A A. These floats are to be arranged at equal distances apart, and in other respects iu manner as exhibited in the drawings.
In revolving the paddle-wheel for the purpose of propelling a vessel ahead, such paddlewheel should be turned in the direction indicated by the arrow f-t-hat is, so that the ends of the iioats shall rst enter the water and thc force of propulsion be exerted against the con` cave side of the bucket.
Furthermore, two auxiliary wingsvor floats, D D, are extended from the spokes of the sidewheels A A to each of the mainiioats O O, such auxiliary oats being arra-ngedin manner as represented in the drawings. They are for the purpose ot' enabling the wheel, when its niotion is reversed, to propel 'the vessel astern, which it would be difficult to do with the main Heats when formed as described. Besides this, the auxiliary floats serve as braces or supports for the main oats.
I claim- The arrangement and combination of the series ot auxiliary floats D D with the wheels A A and the series of Inain fioats C C O,t`ormed and arranged substantially as described.
IVM. H. HOLLAND.
