T0 all whom t may concern:
Be it known that L MARTIN ALFoNs Roir MER, a subject of the Emperor of Germany, residing at Florence, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Wave-Motors; and I dohereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to wave motors, and one of the principal objects of the invention is to provide means of comparatively simple construction to be connected to a sea wall for reciprocating a float by means of the undulating movement of the waves and for transmitting the reciprocate-ry movement into a rotary movement for revolving` a shaft from which power is transmitted to a point where it may be utilized for various pui poses. Y
Another object of my invention is to provide a wave motor in which means are provided for modifying or regulating the action of the waves upon the float with a view to securing a uniform reciprocatory movement of the float to attain a uniform and constant rotation of the driven shaft.
These and other objects may be attained by means of the construction illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a wave motor made in accordance with this invention and secured to a sea wall shown in section, Fig. 2 is a front elevation of the crank shaft, the fly wheels, and connections to the float bar, the latter being shown broken away, Fig. 3 is a top plan view of the wave motor the regulating gate being shown in section, Fig. 4 is a sectional view taken on the line 4-4 of Fig. 3 and made on a larger scale, Fig. 5 is a sectional view taken on the line 5-5 of Fig. 1 looking in the direction indicated by the arrows, and Fig. 6 is a side elevation of another form of this invention, designed for the purpose of operating under various conditions of the tides and surf, the sea wall being shown in section.
Referring to the drawings, the numeral 1 designates a sea wall, and supported upon the top of the sea wall is a suitable bracket 2 having spaced inclined arms 3. Journaled in these arms is a crank shaft 4, and on the outer ends of the crank shaft are heavy fly wheels or pulleys 5, and belts 6 may surround the pulleys 5 and lead to a pulley upon a shaft to be driven for any required purpose. The bracket 2 may be anchored in the sea wall 1 by a rod or bar 7.
A connecting rod 8 is pivotally connected to the crank portion of the shaft 4 at one end, and the opposite end is pivoted to a float bar 9 mounted to reciprocate in guides 10 supported upon brackets 11 suitably anchored in the sea wall 1 by means of bolts 12 and anchor bars 18. On the lower end of the float bar 0 a float 14 is connected, said float being formed of a buoyant substance like cork or an air tight casing whicn will be of sufficient size and buoyancy to opera te the crank shaft 4 when impelled by the waves. Extending outward from the sca wall 1 upon opposite sides of the wave motor are walls 16 which are arranged substantially in parallel relation, said walls 10 having divergent outer ends 17 extending out some distance from the sea wall.
A regulating gate 18 provided with a buoyant shoe 19 of curved form, is mounted l" to move up and down on the guide posts or standards 2O firmly secured in the bed of the ocean and provided with braces 21.
The operation of the invention may be briefly described as follows: Vhen the sea is running high, the gate 1S having the curved shoe 19 at its lower end will float and will rise and fall with the undulation of the l'waves and will serve to break the height and force of the waves sufciently so that when they reach the float 14 they will have a uniform undulating action which will serve to uniformly lift the buoyant float 14 and to give a continuous rotary movement to the crank shaft 4.
Under certain conditions of the tide and turf, it is found desirable to provide means for regulating the action of the float 14. As shown in Fig. 6 means are provided for regulating the movements of the floats and to provide a wave motor which will operate etlieiently in either rising or` falling tides, in which the sea wall 1a is provided with an opening 2a, and extending above the opening 21 is a contracted recess 3 of less width than the opening 2a. A concrete basin 4a is provided in the rear of the sea wall l, said basin being preferably rectangular in form and providing a chamber 5a in which is located a buoyant float 6, which rises and falls with the tide. Connected to the lower portion of the float 6a is a valve or shutter 7 designed to close the recess 3 when the float falls a certain distance with the lowering of the tide to pre` vent the iiuctuation of the Water level due to the Waves only from affecting the surface of the Water in the basin, and in turn preventing the constant oscillation of the float 6a therein and will result in a smoother and more uniform running of the motor. Connected to the float 6 is a shaft 8a mounted in guides 92L connected by means of rods l0 to the sca Wall la. The upper end of the rod 8 is provided with an arch 1la which is connected to a similar rod 8b upon the front side 0f the sea Wall. The rod 8" is mounted in guides l2fL connected by rods 13 to the sea Wall la.
From the foregoing it will be obvious that a Wave motor made in accordance with this invention can be installed at small cost, is simple in construction, cannot readily get out of order and will operate uniformly and constantly for its purpose. Various changes may be made in the details of construction Without departing from the spirit and scope of the invention as defined in the claims.
That is claimed is:
l. A Wave motor comprising a float bar, a float connected to the lower end of said bar, guides for said float bar, a connecting rod pivotally connected to said bar, a crank shaft to which said connecting rod is hinged, pulleys on said crank shaft, ivalls one upon each side of said Wave motor, said ,Walls having divergent outer ends, and a regulating gate provided with a curved shoe, said gate being mounted in guide posts and adapted to modify the action of the Waves upon the float.
2. A Wave motor comprising a oat bar, a float connected to said bar, guides for said bar, a connecting rod attached to said bar, a crank shaft to which the connecting rod is hinged, in combination with a regulating gate having a shoe upon its lower end to ride the wave and to regulate the action of the float.
3. The combination of a Wave motor com- )risino' a float a crank shaft connections be- 50 tween said float and crank shaft to rotate the latter as the Waves rise and fall, and a regulating gate provided With a curved shoe, said gate being connected to parallel Walls extending from opposite sides of the motor.
Ll. A Wave motor comprising a ioat, a float bar, a connecting rod, a crank shaft, means for supporting said iioat bar from a sea Wall, Walls extending outward from said v sea Wall and provided with diverging outer ends, a regulating gate mounted between said walls and adapted to rise and fall upon the Waves, and a curved shoe secured to the lower end of said gate.
5. A Wave motor comprising a sea Wall having an opening therein, a basin at one side of said sea Wall, a float provided with a shutter for closing a portion of said opening in said sea Wall, a rod to which said float is connected, guides for said rods, an
