To all whom t may cmweai: i

Be it lrnownthat'lJlLoUIs ZwIEsLnn, a lcitizen of the United States,l residing at Kansas City, iny the county of Jackson.- and State of ldissouriJ have invented certain new anduseful Improvements in Propellingand SteeringApparatus for Vessels,-of which the following is a specication.

'My invention. relates toliinprovements in Y der which may be controlled with less effort 'than rudders of ytheusual type;

Other objects will hereinafter appear, and in order that the invention may be fully understood reference will nowbe had -to the accompanying drawings, inr which:

Fig, `1 is a. broken "longitudinal central section of a vesselembodyingY the improve ments. n

` Fig. 2 is a broken frontV elevation partly in section l.of the ,vessel ligf'is an irregular crosssectioii of the vessel on line 1II; I1I ofFig. `1.

Fig. 4, is a'. broken plan view of` part of thevhating and clutch rnechanisngi.Yr f

Fig. 5 is a. broken horizontal sectionV on showing the f rudder and associate parts.

Referring now in 7det-ailLto` the various which yhas vloweiand,upper vcompartinentsy .fi and 6, respectively.

. rEhelower coinpartmente is provided with fore and aft cylindrical'housings 8` and 10,

respectively, which, in the present instance are arranged in groups of three, those inythe rear group being in axial alineinent with those in the forward group. v'llhexadjacent ends of the housings`8 and 10 kare spaced apart to leave an engine or motor room 12 containing in the present instance, three motors 14 which are, preferably, of the synchronous and reversible type.

The forward endsof the housingsS have inlets 16 at the bow of the vessel and outlets 18 at their rear ends for the intake and disfguards 215. trally `disposed shaftft, journaled1--inwbear ings /18 and 50, the former of` whichwh'asdlJ stuiiingn-boxg52 to preventlwater from leaking into tbe-inctor ro'ein12 frcin'aroundthe` chargent n water.4 :Drift-wood` andA other dbris isY prevented. Vfrom entering theV inlets l=guards20 ftiXed'to the front of the hullf2. The outlets 18 are equipped `.with

guards21,toprevent theientrance of drift-- wood-and` other dbris. when rotation of the i prcpellers hereinafter described is reversed tebaclc the vessel.

f Aiflach. housing'S is equipped witlian elongated screw propeller 22 havingv a series of convolutions"2aL extendingv arounda central 1 shaft 26 jouiiiialed in bearings 28 and29. rthe' bearings 29 are provided with stufiing bcxes 30 to yprevent water from leaking into the motor room` 12 from around the shaft 2G. The' end of each shaft'26 which extends into the inotci' rooni 12 is `providedwith a slidable clutch member 32 controlle'dby a llever t-wherebyitinay beshiiftedeinto and out of engagement with acoinpanion Vclutch ni'eniber iixe'dly mounted upondihe 'motor slia'ftig. V l.

:Each rear housing 101lias anr inletil@ at the bottom of the hull l2 and an outlet-42 `at the stern of said hull, and `like each `housing 8 has an elongated screw propeller.- 44 sirnlilaito the screw propellers 22. vDbrisiis prevented from entering the` ,inlet .40` by "Each propeller 44:. has .a cen,-

shaftlle. Each shaftaiis provided at its forward end with clutchmeniber 5.1 sl i dably `mountedthereon and controlled by` a lever whereby it niayi be shifted into and out of Aengagenfient with ai companion clutch p member tixcd upon the motor sliaft138. partsT 2 designates the hull 0f the vessel v vwith a plurality of oppositely disposed The upper compartment '6 'is `provided cylindricalhousings'60 and 62, four -beiiig employed in ythe present instance. The housings 60 are arranged in axial alinement vwith thelliousings V62 and have `ports'li at yone side of the hull2 and ports 68rat `the bottom of said hull, as best shown by; Fig. 3.

'Drift-wood and other dbris is prevented 8 and 10 are below the water line and are equipped with propellers 76 and 78, respectively, of the same type as the other propellers hereinbefore described. Each oppositely-disposed set of propellers 76 Vand 78 are mounted upon a common shaft 80 journaled in bearings 82 and 84, the latter having stuffing-boxes 86 to prevent water from leaking into the compartment 6 from around said shaft 80. The shafts 80 are provided intermediate their ends with slidable sleeves 88 equipped at their ends with bevel gears 90 and 92, which maybe adjusted to neutral position or caused to alternately engage bevel gears 94 when the sleeves 88 are shifted through the intermediacy of levers 96. The bevel gears 94 are fixedly mounted upon the ends of a drive shaft 98 driven by a suitable motor 99.

lVi'th the propelling mechanism arranger as shown and described it is apparent that when all of the propellers 22 and 44 are in operation the vessel will be forced through the water at maximum speed. It is also apparent that said propellers will operate under the most favorable conditions as they are not exposed to theraction ofthe waves which subject the ordinary exposed propellers to all kinds of4 stresses. The operation of the propellers 22 andl 44 will also'be attended with the greatestA efcienc'y owing to their large number of convolutions acting on the water passing' through the housings 8 and 10, respectively. Furthermore,

should one ofthe propellers 22 or 44 get out of order it can be readily thrown out of gear with its respective motor 14 through the intermediacy of the intervening clutch mechanism, so that the vessel may proceed on her course.

The propellers 76 and 78 are only vused i in turning the vessel or in docking the same.

CII

Cil

By driving the forward shaft 80 in one direction and the rear shaft 80 1n a reverse d1- rection, which may 'be accomplished byL i tween two other vessels, which a vessel guided by its rudder in the usual manner could not enter or leave.

Referring now to the steering mechanism, f

each of the rear housings 10 is equipped with a rudder 100 mounted upon a vertical post 102, which may be turned by any suitable means such as a handle 104. The post Y.thus render said rudder 100 easy to control. The forward portionsof the rudders 100 are reduced slightly to lit within the rear portions of the respective housings 10, as shown more clearly by Fig. 1.

The rudder-s 100 are used in steeringthe vessel when on the high seas, at which time the propellers 76 and 7 8 areinactive unless it should becomenecessary to make a sharp turn to avoid another vessel or other object.

From theV foregoing description it is apparent that I have provided propelling and steering mechanisms embodying t-he advantages above pointed out, and while I have shown and described rthe preferred construc-` tion, combination and arrangement of parts I reserve the right to make such changes as properly fall within ythe spirit andscope of the invention as claimed.

Having thus described my invention, what I claim and` desire'to secure by Letters Patent,is: ,f

1. lIn a propellingapparatus for vessels a group of parallel-housings in the forward portion ofthe hull Vand having portsl at their ends, a group of housings in the rear portion of the hull having ports at their respective ends andarranged in alinement ,withV the Vforward group, elongated screwpropellers arranged vwithin the respective housings, driving mechanismjwhereby all'of-the pro- .pellers .may be,y simultaneously driven, and means whereby any of the vpropellers may be thrown out of gear while the others continue to operate. Y

2. In a propelling and steering apparatus forvessels a housing ,arrangedy in the hull andhavingports at its ends, an elongated screw propeller arrangedwithin said housing and having a Aplurality of convolutions, 1a driven shaft uponwhich said. propeller is fixedly mounted, a balanced rudder having its forward endreduced and extending into the rear end ofthe housing, and a steering post ,extendingA through the intern'iediate portion of said rudder and journaled in the housing; p .c

i In testimony whereof I aflix my signature, in the presence of two witnesses. Y n Y LOUIS ZIVIESLER.
