To all whom it 'may concern.' through brai'let bearings 15 projecting from 13e it known that I, Tnmits R'Com, a the stern otl the boat. the lower end ot' lsaid icitizen of the United States, residingr at' shaft 1t extending into :teasing 15 which .Memphis in the county of Shelby and State 'f inclosesthe gears a rand to. and earries a6() of Tennessee, have invented certain new and bevel gear lo which is in mesh with said y useful Improvements in Gearing for Motoigears J and It). 'lhe upper end ot' said lshaft Boats, of which the following is a specitiea- 1.t extends into a easing lT and carries` :i tion, reference being had therein to the acbevel gear lh' which is in mesh with a siniicoinpanying drawing. L lar gear l!) carried b v a horizontal `shaft 2t) l This 'invention relates to propelling meehmounted in bearings ilY carried by thenpper anisin for motor boats, and the principal obedge ot' the .stern and which projects beyond ject of thesaine is'to provide a novel type ot' i said stermand entersa Casin' lf here) j driving` tnechztnistn for the propeller by gear .l is motiiited on said shaft Qt) within means' of which theloperation of the pro- .said casing Q2, said gear being in mesh with 15 pellet may he contrt'illed7 and also to provide a similar gear i-l carried by the upper end of y. means whereb)- the propeller may he utilized a vertical shaft Q5 the lower end ot' which .asa rudder. c Q projects into a easing 2V having a bottoni In carrying out' the objects of the inveiisocketed extension in which a pivotal end tion generally stated above it will, ofcourse, 28 of a bracket arm "J is mounted. -said he understood that the essential features bracket arm QJ projecting t'roin the -keg Ilo. thereof are susceptible of changes iii details The end of said shaft :iti within the easing and structural arrangements, but a preferred 2G carries a bevel gear 31 which is in mesh and practical embodiment thereof is shown with a `similar gear 3'.' on the end ol' a .shaft in the accompanying dra-wings. whereiii-H il?. .which projects through the said easing Figure 1 is a-loiigitdinal `sectional view QG and has itl outer end journaled in a bearofthe stern of a boat, showing the improved ingll of a'propeltcr housing 2li. one end ot' driving and steering gear applied thereto. which is secured to a tube :to the upper end Fig. 2 isa horizontal sectional view taken on of which ha a rotatable engagement with the line L-Q, Fig. 1e Fig. 3 is a detail end the casing 2'. and whose lower end has a elevation 0f the bout, Fig, t is u detail threaded engagement with the ta itig tt. fragmentary View of thc main power shaft The lower end of said housing is connected and one 0f the 10059 gear wheels thm-e0 with the socketed extension .27 of said eas- Showjng the gunner Said Shaft to .lug 2li. ]il'tlptlltl' 37 lS lllOitlllQtl till ,lit said gear, n. shaft ll within the. propeller housing 2li. Referring to said drawings by numerals Ihe tube 36 surrounds th'e shaft 33 and has 1 designates a' portion of a boats stern, the 11S PPGI' @lill lllOUniLd m il bl'lllitt brat'- tlooring of which carries an end bearing 2 mg 38- Y for a main power shat't 3 extending longi- A steering lever 39 is mounted within the. tudinally of the hoat. .Said shaft is in secboat and has a pivotal connection with a 40 tions which are leld in slidable engarcment rack 40 which is engaged by a pawl and by means of a t-.utch sleeve 4. A shifting lever 41. A rod connection 42 extends from lever 5 is` pivotallj.' iuountcdton said flooring the steering lever to la crank or tiller arin 'adjacent to said shaft and carriesa cani 6 43 projecting fr oin the tube 36. j at its lower portion which engages between It. will be obviousrfroin the foregoing that; 45 two eollars T and S fast on said shaft so by rocking the lever 5 forwardly the gear that when the saidl lever is rocked, the said 10 will be locked to the sliaftV and .caused shaft will be shifted longitudinally. The to rotate therewith thereby imparting its rear end of the main power shaft has loosely movement to the shaft 14 which 1n turn is mounted thereon two bevel gears J and 10, communicated to the shaft 20, which in turn ywhich are disposed on opposite sides of the communicates its movement to the shaft 35,

hearing 2, and' each gear cai-ries an outstaiidand the latter shaft,communicates lts moveing laterally projecting lug 11 which is mentl to the propeller shaft. The movement adapted to be selectively engaged' by either just described imparts a forward movement of the lugs 12 or 13 projecting laterally from to the propeller. vTo reverse, the lever 5 is the shaft 3. rocked rearwardly which causes gear 9 to be A vertically arranged shaft 14 projects locked to the shaft 3, and thereby impart a reverse movement to the shafts- 14, 2t), 35 and the propeller shaft. To disconnect the cates its movement to the rod 42, and the latter actuates the arm 43 which causes thev tube 36 and the casing 26 to turn and thereby throw the propeller to either the right or left and therebv steer the boat, as will be readily understood.

While in the foregoing description and the kaccompanying drawings `the steering mechanism has been shown as provided with a lever for operatin the same, it will, of course.,v be understoo that other means for operating the same may be used if desired. f

"hat I claim as my invention is 1. A driving and steering mechanism for boats, comprising a main power shaft located within the boat, a ropeller shaft cx tcrior of the boat, a )ropeller thereon, a vertically disposed sha t operated by the main power shaft, a horizontally arranged shaft operated by the vertical shaft and project ing beyond the boat, a vertically arranged Ashaft exterior of the boat andV operated by said horizontal shaft, a. gear connection hctwcen the last mentioned vertical shaft. and the propeller shaft., a housing inclosing the propeller shaft and propeller, a bracket for pivotally supporting said ,housing` and propeller to steer the boat. Y

2. i' drivingand steering mechanism for. boats comprising a.- main pmver shaft within a hoat,rcvcrsing mechanism carried il'iereby, a vertical shaft operated by and connected with said reversing mechanism, a horizontal shaft operated by said vertical shaft, a vcrmeans for shifting said housing; to canse the tical shaft exterior of the boat and operated f by the horizontal shaft, a tube surrounding the last-mentioned rvertical shaft, a casing carriedl oy the lower end of the tube and into which said shaft projects, `a bracket arm projecting from the boat and having a pivhousing having one end connected to Said tube and its other end-connected with said casing, a propeller shaft within said housing and projecting into said casing, a gear con# nection between said propeller shaft and the end of the'vertical shaft within said casing, a propellery on the propeller shaft, andl means connected with said tube for shifting otal connection wita said casing, a. propeller v said housing, casing and propeller and shaft to steer the boat.-

3. A steering and driving mechanism for boats comprising a main power shaft within a boat,` a vertically disposed tube exterior of the boat, a casing projecting from the 'bot- Y i tom of .said tubc,-a pivotal connection be ineen said ,casing and the boat, a propeller shaft having oncend entering. said casing, a shaft Lritenfliirer through said tube and into said casing for operating the propeller shaft, means operated by the main power shaft for operating the shaft Within said tube, a propeller on the propeller shaft, a housingfor the propeller and shaft, said housing having oneend connectedA to saidA tulle and the other end connected with said casing, a crank arm projecting from said tube, a Yshifting lever within said boat, and a rod connection between said crank arm and said shifting lever.

vIn testimony whereof I hereunto atlix my Y signature in presence of two witnesses.
