T 0 all whom it may concern:

Be it known that I, DANIEL M. Prl-xn'rz, a citizen of the United States, residing at Germantovvn, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Twin Steamships or Vessels, of which the following is a specification. I

My invention has relation to a combined twin steamship or vessel, constituting in such type of ship or vessel, a flat bottom divided by a deep and wide medial longitudinal channel extending from prow to stern and with depending projections, and in which channel are arranged a series of paddle-wheels, with respective water tight caps thereover, the said wheels arranged so as to revolve at different. speeds with respect to each other and with buoyant devices, such as, compressed air chambers, in front and on the sides of the ship or vessel, forlessening friction of the body of water in the flotation thereof; screw-propellers on the sides, in pockets, at suitable distances apart and open to the outside and to the bottom of theship or vessel and connected steering rudders in the stern, arranged to act in unison, and to rotate in the same direction.

The nature, characteristic featnresaand scope of my said invention, as above defined, will be more fully understood from the following description taken in connection with the accoi'npanyingdrawings forming part hereof, in which- Figure 1, IS a top or plan view of a combined twin steamship or vessel embodying essentially, as shown, all the characteristic main features of my present. inveption. Fig. 2, is a longitudinal central sectional view through the combined twin steamship or vessel. Fig. 3, is a side clevational view of the steamship or vessel, partly broken away, to show one set of side screw-propellers with partially, actuating means therefor; and Figs. 4 and 5, are respectively, transverse sectional views through the steamship or vessel on respectively the lines w, w, and y, 1 of Fig. 1, to show the coup pressed air compartments side screw propellers, one of the paddle wheels mounted in the wide and deep channel and the depending rojections on both sides of the said longitudinal channel of the con'lbined twin shi p or vessel.

Referring to the drawings 10, is the combined twin steamship or vessel having a Wide and deep medial longitudinal channel 11, extending from prow to stern of the combined structure. At suitable distances apart in the channel 11, are arranged a series of paddle- wheels 12, 13 and 14, as shown with water tight caps a, Z) and c, extending,thereover, as clearly shown in Fig. 2. Each of the paddle-wheels are arranged so as to be revolved at different speeds, by separate engines in the hold of the ship or vessel. In the stern are arranged two steering rudders 15 and 16, connected with each other by a belt or chain 17, and acting in unison, and operating in the same direction, by suitable steering means,

controlled from the ships pilot house, not

shown. Projecting downwardly from the walls of the channel 11, are projections or blades 18 and 19, extending below the respective paddle-wheels, so that in case of grounding of the ship or vessel by reversal of the ships course, the same may, when the tide permits be readily floated off of its grounding, without affecting the paddlewheels, as they are fully protected by the said projections or wings. 18 and 19, as clearly and fully shown in Figs. 4; and 5.

()n the respective sides of the twin body of the vessel or ship in pockets 22 and 22, open to the outside and to the fiat bottom, arc mounted screw propellers 23 and 23, opera led by separate engines, and preferably at greater rates of speed than the respective centrally arranged paddle wheels 12, 13 and H. mounted in the longitudinal channel 11. [n the front and on the sides of the twin structure, near the flat bottom are arranged buoyant. or compressed air chambers 24, 24 and 2-4. for lessening friction of the body of surrounding water uponthe ship or ves- Sol, in action and hence to buoy up the same,

'under the (lead load tending to overcome the effect of sucl'i chambers,'\-vhile ploughing through the body of water.

My present invention is designed especially for deriving a high rate of speed, in nm igaliug or propelling the shlp, not through a deep body of water as they do now. but largely over a thin surface of the actual body. of water in which the ship or vessel is being impelled. By reason of havt l' L'reat width. such a' combined twin structure can roll in a rough or lenipestuons sea, without capsizing or overturning. And by arranging the series of paddle- wheels 12, 13 and 14, in the medial longitudinal channcl 11, of the combined structure and so to operate at. respectively, different rates of speed as already explained, each paddleuheel will draw Water from the one in front and hence keep its action clear of the other, so as to exert respectively their full pro- 'ptlling powers on the ship or vessel. The

arrangement on the respective sides of the combined structures, of senor-propellers, in the pockets open, stated, to the outside and the flat bottom and operating in series on both sides, by separate engines, at high speeds in opposite directions effectually throw the water outward away from the ship or vessel and thus facilitate the travel over practically a thin surface 5 the body of water as Well as to a considerable extent lessen "friction of the actual body of Water on the said series of pad.clle-\vl1ecls in action, for impelling the ship or vessel under the directing influence 01" the rubbers, n-orhing in unison, in the same direction, from the stern of the vessel or ship.

1; Wing thus described the nature and ob of my invention, What I claim as new and desire to secure by Letters Patent z 1. A, combined twin tiat bottom ship or vessel having a medial longitudinal wide channel extending from prow to stern, impelling means arranged, in. series, in said channel and each operating at different speeds from the other, side screw-propellers arrangedin series in pockets open to the outside and flat bottom, and said propellers actuated, at ditl'erent speeds with respect to those of said impelling means, substantially as and for the purposes described.

, 9. A. combined twin fiat bottom ship or vessel having a medial longitudinal wide and deep channel extendingfrom prow to stern, rotary impelling means, in series, arranged in said channel and each operatingat dil'lerent rates oi speed, side scre\vpropellers mounted in pockets on the respective sides, raid pockets open to the outside and to the flat bottom and buoyant-means in front and in the sides, near the bottom of the ship or vessel. substantially as and For the purposes described.

3. A combined twin tlat bottom ship or vessel having a medial longitudinal wide and deep channel with water-tight overhead caps, in'ipelling means, in series relation, in said channel below said caps, side screwpro mllers, in series, operating at diti'ereut speeds and steering means in the stern, operating in unison, in the same direction, substantially as and for the purposes described.

st. A combined twin fiat bottom ship or vessel having a medial longitudimil wide and deep channel with upper Water tight caps and depending projections or wings, paddle impclling means mounted in said channel and each operating at ditl'ercnt speeds with respect to each other, side screwpropellers arranged in pockets open to the outside and flat bottom, and the 'ii-o 'iellers on the res nsctive sides operating in series at dili'crent speeds to that of said paddle in'ipelling means, buoyant; chambers in the front and sides of the twin structure and steering means in the stern acting in unison and at. the some rates of speed, subshmtially as and for the purposes described.

in witness \vhereo't, I have hereunto set my signature, in thc'presem-e of two sub scribing witnesses.
