CHARLES'IR.. STEDMAN, OF'GLEVELAND, OHIO.

To all/whom t may concern v'B e it known that L' CHARLES R. STEDMAN, acitizen of the United States1 residing at Cleveland, in thefcountyjof Cuyahoga and i5 Sf-,ateof Ohio', have invented a new and useful Improvement in `-Vessel-Guiding' Mechanism,v of which theffollovving is aA` specification, the principle `of the invention being hereinexplainedv andthe best modeV in which lit@ If'have contemplated applying that principle-so as to distinguish it from other inventions; l

l"My lnventionhas'genera'l reference as the l vtitle indicates, to vessel guiding mechanism 115 while more particularly to a contrivance for effecting an auxiliary propulsion in a direc- .tion other thanin line `withthe keel.

The object of thel invention isto provide the vessel itself'with a positive control for 20 4turning it inl either direction or for moving git'in asidewise directionv thereby avoiding "expensive vtugging Yassistance and affording absolute precision lin approaching a dock.

AIncidental objects have been first, yto accomplish' the results sought in a comparaitilvely simple and economical manner; second, to require ,little space within the hull; `and third togavoijdv under ordinary circum- AAstances'v all exteriorly projecting parts. f

: inventive conception is'embodied in KV-rneanswhich are hereinafter explained and variously combined in the claims, while the annexed drawing andy particular descriptionl thereof togetherv set forth'in detail certain -means constitutingv my" invention, the ldisclosed Ineans7 however` being but one of various mechanical forms in which the prin- ,ciple of'my invention may be applied.

` Iny Fig.- 1 thevv entire hull of a vessel has been designated by the reference character Mounted in this hull is shown an engine, a'sternpost carrying. the rudder and a propeller inclosed by the stern post. In the exemplihcation seen in the drawing the hull is provided' near each end and only a short distance above the keel with openings a extending therethrough from side to side andgi'nthis instance'transversely of the keel. Thel sides vof the vessel are provided exteriorly withl annular recessesv z2 surrounding the openingsa.

s i tending between Ithe two forward and likewise between the two rearward of the openings respectively I. seat a pair of cylin- 'dricahtubes B. These ytubes B while open ateach endv are water-tight with respect to the hull of the vessel.

Secured to Vthe* interior of the tubes B in any approved manner arek four supporting Ahangers b. These hangers are equispaced and otherwise arranged; such that alternate ones are mainly parallely and adjacent onesv transverse with respect to each other, as clearly seen in Fig. 2.- Thehangers b are adapted to` support between their innermost extremities b2 a Shaft housing b3 provided at 'opposite ends s withybearing members b4.

vversible type,-and sincenothing isclaimed iny Y regard to 'this feature its detailed construc- 'tion is omittedi? f llhe' bottomY of# the tube B is provided with draining facilities asl suggested by the pipe 58 seen in Fig.' v1,. @pposite ends of the f tube VB are provided with a'plur-ality of parallel V upright vanes b whose smallest dimension-'isiseen to be transverse with respect to the imaginaryk axis" of the tube B. These vanes l5? are illustrated in Figs.` 4 and 5. 'Their purposel vis to prevent entrance'into the tubes of largeobjects' likely to interfere Vwith or obstruct the vpropeller 67. An auxiliary drivingA shaft (j may be operatively connected at will with the engine through "the'f'med'iu'm of a lclutch c.- This-'clutch is shown in Fig. l and since'its particular con! struction is of no moment here, a detailed representation of it has also been omitted, The other extremity ,ofthe shaft C projects into the forward tube B and also into the housingb3 where it is provided with a com? plementary bevel gear c2 whichris in mesh withthe bevel'gear Z96.- In this "manner as will now be'perceived, power may be transmitted from the engine such that therota tion of the shaft C effects the rotation of propeller b?. d v. p v

Supported uponeach end ofthe tubeB is a Vcasing D. This casing is secured tothe sideof the hull by means of a4 plate 0V, provided interiorly of the casing Dvwith an the shaft b5 and hence the revolution of the .opening d2.. Seatedrin thel opening cl2 and projecting into the casing D .is abearinggg member cl3. About midway of the casing D ,is an upright partition d4, providedwith'a smaller opening Z5 which is yin line with the imaginary axis of the bearing d3. l

A stub shaft E is mounted for movement :in the bearing. cl3.' This shaft is provided inwardly adjacent its journal in thek bearing 'da vwith aspliney eiand in turn inwardly adjacent `therspline e the shaft E is grooved circumferentially Vvas designated by e2V and best seeninFig. 6. The remainder e3 of Athe shaft E is of smaller `diameter and ,ex-

tends through the openinga5 inthe partition (Z4. Upon the extremity of this reduced portion ofthe shaft E a pin e" is provided, while interposed between this pinand the v partition Ztis a compression spring e5.

Keyed upon the spline'c is a worm gear'ec.

An' upright operating rod S67 extends into vthe casingD, and'onits inneryextremity supports a pinion` es adapted `tolmeshwith the grooves e2. YA second operatingrod e9 likewise extends through thecasing D land stern of the vessel has thefmain -sh'aft C "extending into it at which point the latter .carries a sliding clutchfc3 whereby tofcon nectVA or; disconnect a,y beveled'. gear c4.

YMounted interiorly of the @stern tube Bjare bearingsa'sv adapted to'support axiallyy of said tube a stub-shafta1 yupon'l which vis mounted ."a propeller as' and also another beveled;` gear' a? adapted to .mesh jwith: the

bevel gearvct In this manner depending upon whether lthe gear c4A isin or-*out yof engagement with the gear a the lateral propulsion of the stern of the vessel may be adgditionally effected or 'not asthe case may be.

` rI he operation ofthe mechanism forfmo'v- 'ing a Adoor F, assuming the-samev to be in Vits'closed position asl seen in Fig. 4,' is therefore i as follows: Prior' to establishing ya iconnection'between the shaft C and the en-` gine preparatory to Vdriving the propeller 57, the two doors F of anyparticular tube B should be opened and preferably entirely removed "from vin Yfront of the opening,y

thereto. kTherodvefris first rotated either by hand or otherwise, whereupon the shaft E is moved outwardly: against the vaction of thespring e5. During suchoutward'` moveyment the door F is necessarily *movediv out -of the recess Va2 and lbeyond the outer sur- Y V,face of that portion of the hullA which is immediately above the casing D. i Next, the

rodcgis' rotated and hence also the worm ce. -In consequence of the rotation of the latter the shaft El lis itself rotated. and the door F ,swung upwardlyl as indicated in dotted .linesrin Figui. After` the two doors F of one or the other of the tubes B have' been fropened,.power mayl be transmitted to the propeller b? whereby the water is propelled `through the tube B andthe corresponding .end o-f theV vessel caused to move in the reverse direction. It is obvious that a simultaneous operation .in reverse directionsV of ythe propellers in the two tubes .B kwill confV -trive-to turn the vesseleven more quickly, andY similarly their 'simultaneous 'operation in the same'direction will cause ,th'evessel' asa whole to 'move' sidewise. 1
