DAVE TAYLGE, OE WES? IZOINT, MISSISSIPPI Application filed @ctoher 11, 31928. serial lilo. 5311,7232.

The invention aims to provide a new and or e in w ich le in subplanes close to the sides of other small boats, of the general ty two propelling paddles are opera stantially vertical the boat.

The paddles are ivoted to their carrying members so that t ey operate when these members move in one direction and merely idle when they are moved in the other direction, and it is a further and important object to provide unique means for turning the paddle-carrying members one-half revolution whenever desired, so that the direction of travel of the boat may be reversed, or by reversing one paddle and not the other, or vice versa, the craft may be readily steered.

It isyet another aim to provide a construction which may be operated entirely by the occupants seat if desired, leaving his hands entirely free to handle a gun, trolling rod, etc.

Yet another aim is to make provision whereby the propelling means may be operated by hand if desirable.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.

Fig. 1 is a equipped with t e invention.

Fig. 2 is an enlarged perspective view of one of the paddles and associated parts.

Fig. 3 is an enlarged vertical section on line 3-3 of Fig. 1.

Figs. 4 and 5 are horizontal sectional views on the line 4--'5 of Fig. 3 showing the paddle in idle and operative positions respectively.

Fig. 6 is an enlarged longitudinal sectional view as indicated by line 6-6'of Fig. 1.

Fig. 7 is a vertical transverse sectional View on line 7'Z of Fig. 6.

Fig. 8 is a fragmentary erspective view showing the manner in whic the propelling means may be held clear of the water when desired.

The form of construction herein disclosed will he rather specifically described, with the understanding that withinthe scope of the invention as claimed, variations may be made.

erspective view of a boat M) denotes a pair of bearings which may be secured by screws ll or any other desired means to opposite sides of a boat B. 12 has reference to a similar air of bearings secured 111 any desired way to t e boat at points spaced longitudinally from the bearings 10. The propelling means are mounted upon the bearings and as the construction for each side of the boat is identical with that at the other side, only that at one side w-illjbe described in detail.

Disposed at, the outer end of the bearing 10, is an upright lever 13 whose lower arm extends considerably below said-bearing and is provided with a vertically elongated tubular bearin 14; secured thereto by any desired means sue as the yokes denoted at 15. The

n per arm of the lever 13 extends somewhat a ove the bearing 10, is bent laterally inward at 16 and is then extended downwardly at 17 at the inner end of the hearing. A fulcrum in 18 passes through the bearing 10 and the ever portions at the opposite ends of said bearing. The lever portion 16 is provided with a rigid 100 19 adapted to receive the lateral lower en 20 of the handle 21 shown in Fig. 7, so that the lever may be oscillated by hand if desired. Ordinarily, however, this lever is operated by foot as hereinafter explained.

'llhe upper end of the shaft 22 is rotatably and slidably received in the bearing 14 and the lower end of this shaft carries a paddle which preferably consists of two pivoted sections 23, stops 24 being secured to the shaft to limit the swinging of said paddle sections in one direction so that when the paddle is in this condition, it will function. Upon movement of the paddle in the opposite direcshaft-turnin means preferably'comprises a helical cam t 25 in the'bearing 14 and a .co-acting stud or shoe 26 on the shaft 22.

This rovision effects smooth and easy turn p i f its sectional nature permits it to be readily the shaft 22 a half revolution when it is slid to the-proper extent in the necessary direction. Before describing the means for Y sliding the shaft, the foot-actuated means for swmgm' the lever 13' will be explained, as in the pre sent disclosure one is dependent upon the other.

At the inner end of the bearing 12, 1s a foot lever 27 whose lower'arm-extends con? siderably below said bearm and is provided 3 with a suitable pedal 28. e upper portion of lever 27. is shaped in the same manner as 4 the upper portion of lever 13, and a fulcrum in 29 passes through the portions of this ever 27 at opposite ends of the bearing 12.

The transverse upper art of the lever is with openings 2. At 33, universal connections are provided between the rod' 30 and the levers 27'-v13, and the connections between rod and levers is also such that said rod ma a foot-actuated crank 34 by means of which the rod may be turned. The other end of this rod is provided with a crank arm 35 to which the upper end of a link 36 is pivoted, and the lower end of this link has a ball and socket or other equivalent connection with the upper end of the shaft 22. By this construction, rotation of the rod 30 effects sliding of the shaft 22 in the bearing 14 and at this time the co-acting means -26 cause one-half rotation of said shaft, thereb conditioning the propellin means for driving the boat in the opposite irection.

, An appropriate spring device 38 acts upon the crank arm 35 or other desired portion of the contrivance to normally hold the rod with said crank arm in its downward position.

It will be seen from the foregoing that by either hand or' foot power, the. propelling means may be easily operated and that the direction of travel of the boat may be reversed with ease whenever desired. .Moreover, one paddle may be reversed without the other or vice versa to effect steering. While the paddles normally project considerably below the boat, they are free to swing suflicidntly to clear any obstruction over which the boat will pass, and if it should I be desirable to hold the paddles in elevated positions, this may be done by hooks 39'enrotate. At the end of the rod ad-. jacent t e lever 27, said rod is provided with.

and shaft in the ot 13,ras shown in Fig. 8.

he invention mag be easily and inex ensively constructs of light weight and reach it may be easil fastened in position upon the boat and it wi lbe observed that the construction is such' as to permit adjustment according to the length of the craft, the arrangements of the seats and the desires of the person or persons who are to occupy the "craft.

The details herein disclosed may be folgageable with the upper ends of the devers lowed if desired but attention is agam invited to the fact that within the scope of the invention as claimed, variations may be made.

Springs S are peferably used to return the movable parts a r each thrust by the foot.
