MARINE PEDOMOTOR.
Application filed February 21, 1925. Serial No. 10,845.
This invention relates to improvements in water boats and more particularly to a marine pedomotor.
One of the important objects of the present invention is to provide a. marine pedomotor which may be easily and efficiently operated, the same being further simple in construction, inexpensive and furthermore adapted for the purposes for which the same is designated.
Other objects and advantages ofthis invention will become apparent during the course of the following description.
In the accompanying drawing forming part of this specification and in which like numerals designate like parts, tl'iroughout the same:
Figure 1 is a top plan view of the boat embodying my invention.
Fig. 2 is a central longitudinal sectional view thereof.
Fig. 3 is a bottom plan view, and
Fig. 4 is a cross sectional view taken approximately on the line 1- 1 of Fig. 1.
In the accompanying drawings wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates generally the water boat the same comprising the floor 2, the same being secured on the cross beam 3. The sides and ends of the boat are designated at 4 and 5 respectively. The boat is substantially rectangular in design as clearly illustrated in the drawings. Suitable reinforcing means 6 extends around the sides and ends of the boat adjacent the floor 2. V
The rear portion of the floor is cut out as illustrated at 7, the cut out portion being arranged intermediate the side of the boat and between the longitudinally extending air tanks 8 and 9 which are supported on the bottom of the boat for rendering the same buoyant. The forward ends of the air tanks have their sides tapered while the rear ends of the air tanks have their bottoms flattened and incline upwardly.
A pair of supporting brackets 10 are secured on opposite sides of the opening 7 intermediate the ends thereof. A shaft 11 is journaled at its respective ends in the upper portions of the brackets. Carried by the shaft 11 is the paddle wheel 12, the same being of any well known construction and being adapted for operation within the opening 7. A substantially semi-circular casing 13 extends over the paddle Wheel and the supporting bracket for the shaft thereof.
A crank shaft 14c is supported transversely on the spaced brackets 15 provided therefor at a point forwardly of the paddle wheel 12 and casing 13 therefor. A pair of hook cranks 16 and 17 is provided at each end of the crank shaft 1d and clearly illustrated in Fig. 1 and the purposethereof will hereinafter be more fully described.
A sprocket wheel 18 is secured on the intermediate portion of the crank shaft 14 and a similar sprocket wheel 19 is secured on the shaft 11 which supports the paddle wheel 12, the aforementioned sprocket wheel being in alinement and adapted to extend thereover is the sprocket chain 20. This provides a means whereby the crank shaft 1 1 when actuated through the medium of the foot crank will transmit rotary motion to the shaft 11 and the paddle wheel 12. It is of course to be understood that the forward end of the casing 13 is provided with suitable openings to accommodate the passage of the sprocket chain therethrough so as to interfere with the operation of the paddle wheel when the casing is in its normal position thereover.
A pair of supporting feet 21 are arranged on the forward end of the casing as clearly illustrated in Figs. 1 and 2 of the drawings. The feet are arranged adjacent the foot cranks provided at each end of the crank shaft so that two persons may be seated in sucha position as to facilitate the actuation of the crank shaft 14 through the medium of the foot cranks 16 and 17.
The usual rudder 22 has its post 23 extending upwardly through the floor 2 at the stern of the boat. An arm 24 extends laterally from the upper end of the post and provides a means for controlling the movement of the rudder. A pair of steering posts 25 having their lower ends extending through the bottom 2 of the boat 1 adjacent the respective ends of the crank shaft. Steering wheels 26 are mounted on the upper ends of the steering posts and are adapted to be actuated by the occupants of the seats 21.
A cable 27 is associated with the free end of the laterally extending arm 24 and is attached to a suitable drum 28 mounted on the lower end of one of the steering posts, suitable guide pulleys 29 being provided in connection with the cable 27. This construction enables, the boat ,torbe steered in a simple and efficient manner. Additional feet are arranged at the sides of the bow of the boat. Access to the boat is had by way of the passages 31.
In operation, either one or two persons may propel the boat and by being seated on the feet 21, the feet of the occupants will be each in engagement with the foot cranks oi the crankshaft and, by operation of the same," the crank s mi t 1s will t *ansn'iit rotary motion to theshatt 11 and the paddle 12, thereby. causing the paddlewheel to rotate and in turn move the boat. along the surface of the water.
,ltflwill; thus'be seen from the foregoing description that a marine pedomotor has been provided which may be eiiiciently and easily operated, thesame being further of such constructionas to/ render it strong and durable.
llVhile I have shown the .prererred embodiment. of my invention, it is to be understood: that various changes in the; size, shape and arrangement of parts may be resorted towithout departing from thespirit not the invention andthe-scope ot' tneappended claim.
Having thus described my invention, what I claim as new is In a marine pedomotor including a floor, side and end walls extending upwardly from the floor, a v pair-of--air tanks extending longitudinally on the bottom of the floor, saidaloor being provided with an enlarged opening, a pair or upstanding brackets secured 0n the floor adjacent the longitudinal sides of the openin a transverse shaft: journaled at its respective ends in the upper portions of the brackets, a paddle wheel mounted on said shaft and extending through the opening, a casing over said paddle wheel and said bracket, a crank shaft supportedforwardly of the casing andarranged parallel with respect to the iaforementioned shaft, alignin sprocket wheels on the respective shafts, a sprocket chain extending .over the sprocket wheels and adapted to extend through an opening provided therefor in the frontside of the casing, toot cranks on the crank shaft for-actuating the same, and
means for steering the pedomotor.
In testimony whereof I a'l'lix my signature.
