ROWBOAT Moron.

Ap'plication filed February 14, 1927. "Serial No. 168,223.

@to thestern of a row boat or like small water craft, and which carries :apropeller that is revolved by a handlecarrying fly wheel,

meansfwithin easy access of the operator bemg provided for reversing the propeller, andati'ller rod also in close proximity to the operator being connected with a tiller or rudder in a novel construction'whereby a boat can be propelled in a forward or reverse 16 direction, readily guided or stopped in an easy manner and with a minimum amount of physical exertion. I A- further object is the provision of a means for this purpose which shall comprise 0 few simple parts, that may easily and securely be attachedto the sternvof the boat or removed therefrom, the actuating parts for the propeller being wholly enclosed and the operating mechanism being removable so that the boat cannot be operated except by authorizedpersons. 1 Y To the attainment of' the above broadly stated objects and others which will pre- "sent themselves as the nature of the invention is better understood, the improvement further resides in-certain other novel fea- 'tures of construction, combination and op- ,erative, association of parts, one satisfactory embodiment of which is disclosed by the accompanying drawings.

"In the drawings: I

Figure 1 is a view of the rear of a small water craft having my improvement attached. thereto, the craft being in section. Q Figure 2 is aside elevation of the improvement on a somewhat enlarged scale, one of the plates of the casing being removed." F-igure 3 is a detail longitudinal sectional view to illustrate the manner in which the shiftable gears engage with the beveled pinion on "the shaft of the propeller.

Fi ure 1 is a sectional view approximately 2'') on the'line -1-4 of Figure 2. e V

Figure 5 is a detail sectional view through the fly wheel to illustrate the manner in which the sameis detachably connected with the shaft therefor. v Figure 6 is a detail sectionalview to il- 5 lustrate the connection between the lever and the solid shift rod or shaft.-

The back board or stern 1 of 'a small water i craft 2 is illustrated in Figure 1 of the drawings. My improvement is clamped on the stern board 1. The improvement contemplates the employment of a casing 3 that preferably includes a main body portion and a. removable face plate 3, the latter being disconnected from the body in the showing of Figure 2 of the drawings. The casing?) has both ofits ends enlarged, the upperenlargement 1 being of a substantially-spherical formation and being formed with ahollow inwardly extending hub portion5. The lower enlargement '6 is of an elliptical formation and isfformed with an outwardly directed hub portion 7. vIn the casing, adjacent to the

ends

1 and 6 thereof there'are preferably arranged yoke members 8, and between these yokes there are bearing blocks 9 for a hollow shaft 10. The yoke members have their arms connected by bolts 11, and

these bolts contact with the outer faces of the bearing'blocks 9. Arranged around the hollow shaft 10, and if desired secured j to the lower bearing blocks 9 there is a collar 12 and surrounding;- the said hollow shaftand exertinga tension between this'collar and the hub there is a helical spring 1 1.

"The .wheel 13 has its hub fixed on the elongatedsleeve 15 through which the hollow shaft 10 passes' Also fixed on the sleeve wheel 16 that is arranged face to face with the wheel 13, The hub of the wheel 16 rests on a bearing member 17 which is fixed to the lower end of the hollow shaft 10 by removable means 18. It should be stated that the means that secure the

beveled gear wheels

13 and 16 to the sleeve 15 are also in the natureof remoyable elements. The lower. end of the hollow shaft may be closed and the same is received in a cup-shaped bearing 19. Between the bearing 19 and-the bearing'member 17 there is a race-way and anti-frictional'elements 20. The cup-shaped lvided with a flared depression for the reception of the pointed end of a screw member-21 which is threaded through the lower center of the part 6 of the casing '3, a binding nut 22 being arranged on the screw for holding the same properly positioned. The pointed end of the screw provides abearing for .the'member 19 and alsoserves as an adjusting means for regulating the position of hearing has its lower and closed end pro the

beveled gears

13 and 16 with respect to" portion a end 31 oil the shaft influenced doe; 33 that propelling the hoa t.

. such n'iovelnent will contact; with the .mesh with the pinion and the a beveled pinion 25 on the shaft 2-22 for the propeller ill. The propeller is oil the screw type and its shalit 2t passes through hearing blocks 26 similar to the hearing hloehs ll. the said l'iearines 2th however, being; arranged in the huh T of the part (3 of the casing. Also the shaft 21': preferahly passes through. a packing}; hex that; closes the outer end ol the huh 7.

The hollow shaft 10 has lixed on its upper end a beveled near 2? that is in mesh with a similar great tired on a shaft 29 that passes throuegh hearings 30 in the huh I i ot the upper enlargement or head t at? the casino" 3.

This hall head is received in a sr'rrlcot n in one end at a lever The lever is pivoted, as at -Lt(l. to a aup mrt ti on the upper head at; of the casing it will he apparent that hy actuating the lever 45 longitudinal movementwill he imparted to the rod "l-r'tl so that the same will he moved in an upward direction. and hr virtue of upper walls of the elongated o 'ienine a 38 in the hollow shaft J0 and also hy virtue o'lf such JIIUVtIl'lOlll? will raiee the sleeve to hiring the gear 13 out ol mesh with the propeller shaitt pinion and the near .16 into nlesl'i with such pinion. hen the gear 13 is in Ely wheel turned. the sha lt; 3t is designed, to turn the propeller to more the heat in a 'li'orward direction but when the parts are shifted, as

just described. the turning of the fly wheel in the same direction will reverse the turning of the propeller 5 25 so that the heat will he propelled in a backward direction. Of course, it: necessary that a pressure be exerted on the lever :45 as long as the pro peller moves the boat rearwardly.

.lournaled in suitable hearings d8 on the outer side of the casing; 1, there is the vertically disposed tiller or rudderoperating rod ll). The outer end oi. this rod has a L'l'illllittl portion provided with a handle 50. To the rod it) there is connected the rudder fit. that plate and as disclosed. by the drawings has its lower edge notched, as at 552, to receive the hlades ot' the propeller 25 therein. The outer portion 53 ot the rudder 51 has its end terminating approrcirnately in a line with the axial center of the hub ol? the propeller or projects slightly therehelow. The rudder thus con'iprises a comparatively wide member which will ellectively contact 'lhe rudder is in theiniture of a with the water is properly guiding the boat when the handle 50 is operated. ilauitahle means may he provided to prevent the tree turning); ol. the rod 49.

This arm has its upper end offset to provide a. linger The tii'iger designed to he passed through. a socket of the otlset end 56 ot' a jaw member 57. Threaded through the jaw memher there is a handle operated 60. This hip; (30 is designed to rest on the upper edae ot the stern hoard. l, at the heat 2. lhe jaw it will he noted loosely connected with. the supporting arm 54. it being understood that the screw 58 past-es freely through an opening in the jaw. and the huh portion ot? the handle tor the screw contacts with the outer tare ot' the jaw. 'llhus hy turning the screw the jaw will he tori-ed toward its sup 'iortiugr arm hel: to :torce the said arm against the outer 't'are ot the hoard 1. while the jaw trirtionally engages with the inner face ol. the said stern hoard. In this manner it will be seen that the device is eil eetively held from movement; in any direction when clamped. on the boat.

The simplicity of my construction and the advantages thereof will he perfectly apparentto those skilled in. the art to which such invention relates when the foregoing description has heen care'hilly read in conneetion with the accompanying drawings. but obviously I do not wish to be restricted. to the precise details herein set forth and, therefore. hold myself entitled to such changes there'trom as fairly fall Within the scope of what I claim.
