-T 'tchem it may'cencerh I Bert'known that I, HERMAN OVENTROP, at.

citizen of the United "States of America, re

siding at the city of St. Louis ini-the State Missouri, have invented certain new and useful 1m rovernents inMarine Vessels, of which the fo lowing, is a full, clear, and exact des script-ion reference being had to'the accommnyi'ng' drawings, foi'iningpart ofthis' specithat is equipped with a H opellerlofbuoyanti nature, whereby the hu of the vessel is'ele-f vated from the body' of [water on which the vessel floats, thereby eliniinatingbfriction between the hull of the vessel andjthe water,

and making it possible, due to gthe eliminate tion of this friction, to, propel the vesselat a higher rate of speed'than that which is pose sihle with vessels'of ordinary construction.

Figure I is a side elevation ofniy marine vessel. 'Fig 11 is a top or plangviwof the steering end of the vesseL- Eig.""I1I is an en{ larged planner bottom view of-fan end'por 'tion of thewessel. Fig. IV is an enlarged side elevation of an end portion of the vessel.

Fig. V is an enlarged viewof portions of the propeller floats at an end of the vessel with the decks of the vessel shown partly in eleva tion and partlyin vertical section. Fig. VI

is an enlarged section taken online VI-Vl, Fig. lV with one of the propeller floats shown partly in elevation and partly in lon itudinal section and its centralportion bro en.out. l ig.-\"ll is in part an elevation and in part a vertical section ol members of the propeller Fig. Vlll is a top or plan view of members of the propeller floats illustrated having their central portions broken out."

In the accompanying drawingsz A designates the body of my vessel which is 'preferably provided with a lowcr deck'B and 'an upper deck (5. 'l'he-body of the vessel may, howeverbe ofany suitable construction other than that illustrated in the drawings; 1

The lower deck B of the vessel has deck extensions B projecting beyond the upper;

deck C and is provided, near its ends with openings 1), one of which is seen in l i'g. 111, through whiclrmy propeller, to be herein? alter described, operates.

All-of the parts flanged inwardlywithin the bodies} oneof the wardly;t"as seen in Fig; VIn; 'Ifhe floats 2 have "secured; to them hinge ears-or members 3 preierabl' attachedto/the floats by rivets and whic v protrudebeyond the sidesof the *lioats and are perforated to receive shafts 4 bv which the floats are united to each other. The shafts 4 are retained in positionin the hinge ears 3 by seating them in bracket arms "'5 securellto the floats and'sha' ed similarly to the hinge ears each shaft being rigidly held'in th bracket that receives it, by suit able means,'such as a set serewfi; 17 are guide wheels provided wit centrallyarrangedfianges 8. These guide wheels are loosely fitted to-the shafts 4 and are ada ted to operate upon-the continuous ftracks B with their flanges in positions bewheels on the tracks.

'9 designates tie-rods that extend longitudinally of the buoyant I ropeller and serve to unite the shafts 4 whic i connect the floats 10 fitted to said shafts. It will-beseen that i by the described construction, the floats 2 I are so connected to' each other as to furnish i an endless chain of floats Wllloiwill operate l around the continuous tracks D and be guided I by said tracks into the water on which the vessel floats and then emerge from the water i to travel-inan upper course above the lower i deck of the vesse 11 designates a re eller shaft that is suit.- ably mounted in t 'ie ody of thevessel and i to which'power may be communicated in any 1 suitable manner. This shal't has fixed to it a deck beneath the upper deck C, as seen in I of the floats '2 arejlprferably of. sheet metal and riveted-to each other, the tie-plates 'being 2 and theends of which areatt'ached to collars.

' These tracks, see Figs; Y1 and Vi preferably consist of airs of channel rails'l that'are s aced. bac to backand-separated from eac other to furwheels t0 be hereinafter described, operate.-

2 designates floats that comprise U .sha ed I ishellbfodies having flanged heads seate. in

hperipheral I tween the rails 1 of said tracks for the purpose of presenting lateral movement of the v pair of propeller operating wheels that comprise spider arms 12 terminating at their outer ends in sockets 13, and connected to each other by links or stays 14. The propeller operating wheels are adapted to be so rotated that the sockets 1.3 of the wheels will be moved consecutively to the hinge ears connecting the floats 2, as seen in full lines-- Fig. VI and dotted lines Figs. I, IV and VII, whereby said hinge ears are engaged b said wheels and movement is imparted to t e entire chain of floats 2 for vessel propelling action.

It'will be readily perceived that the floats of my propeller serve at all times to buoy the body of the vessel with which the ropeller is associated, whereby the hull of t e vessel is u held out of contact with the water so'asi-to o viate friction between the hull and the water, and that the floats at the same time act as'propellers for the vessel,-due to their 'being kept in motion around the continuous tracks by I claim. r 1. A marine vessel comprising a body having a deck constructed w1th propeller 0 enings near its ends, a pair of continuous e lipwhich their movement is directed.

I tical tracks extending und er and over the deck and through the propeller openings and each consisting of a air of channel rails s aced apa rt, back to ack and providing a ange way, a continuous series of floats provided with arms adapted to engage the connecting hinges of the seriesof floats. I

2. A marine vessel comprising a body having a deck constructed w1th propeller 0 enings near its ends, a'pair of ,contlnuous e 1i tical tracks extending under and over t e deck and through the propeller openings, a

continuous series of floats provided with connecting hinges and guide wheels running on the tracks, connecting hinges, and a rolpeller shaft. having a pair of operating w ee s each provided with arms adapted to engage the connecting hinges of the series of floats.
