-To all whom it may concern:

Be it known that-I, DANIEL WINEEfof Lockport, in the county ofNiagara and State of New York, have invented a new and useful Improvement in the Mode of Constructing Steam-Vessels 5 and I do hereby declare `that the following is a` full` and exact description thereof, reference being had to `the accompanying drawings, in Which-f y Figure l isra horizontal section, Fig. 2 a transverse vertical section, and Fig. 3 a front elevation, of my improvement.Y

wings and revolvin gon suitable bearings With-` in cylindrical cases open at both ends to receive Water, said air-cylinders, bladesgand theirI inclosing-cylinders (being of suitable length and diameter) `constituting the chief part of the hull of the vessel, the Inaindeck and cabins thereof being built abovethem.`

As represented in the drawings,`A A are a pair of cylinders, preferably conicalor poin ted at their` forward ends, and made ot'- metal plates with joints tightly riveted to exclude Water. These cylinders are nearly the length which the deck of the Vessel is designed to be, and are provided with journalsV a, b at either i end, which restin bearings in the cross-arms C C `of the inclosing-cylinders B B. These cross-arms are shown most` clearly in Fig.`3, which is a forward-end View, The cylinders A A have securely attached `to their outer surfaces helical rings or blades d d, preferably four in number, which start fromtheforward end and continue the IWhole length. These spiral blades project sufficiently to extend c `nearly to but do not touch the outer or inclosin g cylinders, B B, leaving them freeito revolve therein. The outer cylinders are also constructed of metal plates of sufficient thickness c to retain their form, and are connected together at their sides, and strongly braced and trussed, if required 5 and from the two outer sides of the pair the sides of the vessel are carried up, as represented in dotted lines, lto sufficient height for decks and cabins, the lower being built `closely to or upon the tops ofthe cylinders.

and planking, forming an air-chamber, g, which adds tothe buoyancy of the vessel. j', is also provided. A similar air-chamber, gf, 'is formed by tightly inclosing the space between the lowerdeck and nppersides of the cylinders. Theseparts so constructed constitute the hull of the vessel, which, when loaded,

sinks solas to` submerge the greater part of y the cylinders, `e e being the Water-line.

i Rotary motion isfimparted to the Win ged air-cylinders A A by` means of their being connected With a steam-engine by cranks and pit-3 man applied `to the, rear journals, b b, or by they revolve.

Cylinders'A A and chambers g y being filled with air give buoyancy to the vessel, and the inclosingturnks B Bropenat their ends and presenting` only their edges to the water, meet with very little resistance. The water being confined within cylinders B B is acted on by therot'atin g blades during its passage through their whole length, as it cannot be forced laterally away by their motion or displaced, eX- cept in one direction, that counter to the direction inl which the boat moves. Thev displaced Water is discharged with great force and velocity from these, trunks `or cylinders directly back,so that all the face of its current is exerted -on` theresi'sting medium of the Water to propel the Vessel forward. i

They are constructed with transverse compartments, so that in ,case of an accident The arms c c, which sustain the bearings a" A- rudder is employed in Y speed in smooth water, and the construction"` above their points of junction, and a horizontal line touching' their peripheries to form a series of air-chambers, substantially as shown and described.

In Witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
