\- following is a speci-dcation.
This invention relates tol current motors, the invention being designed to furnish a .cheap and effective power generating machine oit. snel] ctmstrnction that avi'nodeinte current. oit Water may be utilized for the pui pose of developing power for use in facto-l Y ries and for ruiming pumping and other nia* chinery iorthe purpose oit' .raising water and irrigating ground, :for mining purposes and.
fordriving dynanios, etc. lilith. 'the above and other objects in View the nature of which will. more fully appear as the description proceeds, the invention consists in the novel construction.y combination and arrangement ot' parts hereinafter fully describetl, illustrated-and claimed.
Figure 1 is a plan View of a current motor embodying the present invention. Fig. 2 is a vertical. longitudinal section through the same. Fig. 3 `the line 3-3 of l? Fig. #l is a detail perspective vien' of a corner olf one et' the current boards. llig. 5 is a detail perspectivel vien' of one of the side chain links. llfig. 6 a similar view of one of the center chain link members. llig. T spective 'View of one of the guide pins.
In' carrying out the present invention I employ a pair ol' llo-ats 1 land extending vsubstantially parallel to each other and connected by cross bars 3 and -el ar *tinged respectively at the top of the floats and in a lo'vver plane above tlie surface of the Water, as indicated in Fig. 8.
5 designates oblique or diagonal. braces for forming a rigid braced connectionA between the oppositely arranged floats.
l rlhe floats are provided at their forward ends With cable rings 6 to which suitable anchoring cables are adapted to be connected for holding the structureas a whole in posi tion. to have the current boards hereinafter Vside with a plurality of brackets T'forming' sockets in which are received the outer er n vertical" cross section on' a detail perti'emities ot' suitable stay bars or braces (not shown) extending` :troni the shore or bank .ofthe stream to vhold thestructnre at a snitable distance front the shore. The mechanisin co1n]n'ises essentially a pair-oit' sprocket wheel shaft'ts and 9 mounted in bearings l0 secured to beams 11 on the inner .sides oi the limits l and as shown in Fig. 3, said l-ie'ams 1l extending lengthwise of the floats, Beneath the beams l1 are arranged parallel guides 12 which extend parallelto `the beains 11 and are. securely fastened to' the inner sides of the lioats so as to leave intewening passageways or channels 12%. the purpose. of' which will hereinafter a ppea r.` '4 i Eaten of the shafts 8 and9 is. provided adjacent to the .floats with sprocket wheels 14 lasty thereon and around` each run side sprocket chains 15. llachof'said shafts has also fasttherefni a. centrally arranged sprocket .wheel 1i' and around said sprocket Wheel runs a central chain 18. All of 'these chains are endless andare adapted .to carry an endless` series ot' current boards 19. `Each of these boards 19 is provided at opposite corners thereof with lugs 19 .carrying outwardly extending pintles 20 which pass through eyes 21 on opposite transversely alined links 22 of the side chains 15. The.
pintles 2O are of sntlicient length to project beyond the links of the chains land enter and travel lengthwise of the groove or channel 13 betweenthe guides 12 hereinabove described. lhisprevents the sagging of the chains in the bottom runs thereof and also acts to support the current boards 19. Each current board is also provided intermediate its ends with a bracket 23 having an eye 2.4- adapted to receive one of the coupling pins of the links of the center chain 18, whereby all of the current boards are connected to the central chain as Well as to the side chains 15. Stay chains 25 and 26 connectthe free edges ol the current boards 19 to links of the'` lever 28 which is fulcrulned intermediate its ends as shown at 29. One end of the lever is bent to extend inward into an arcuate limiting slot 80 while the bolts 27 extend in opposite directions throughsuitable guides 3l on the current boards.` When the lever 28 is I. rocked in one direction, the opposite ends of said bolts resting on the -lower guide 12.
This causes the current boards toassume a horizontal position, in which condition they are propelled along the lower run, above the surfaceof the water and consequently not being eected by the current.
To set the current motor in operation, the levers 28y of the several current boards are operated in the opposite direction so as to draw the bolts 27 inward. This allows the free edges of the current boards to swing downward to the position shown in Fig..24
where they are acted water. y
In Figs. 1 and 2, I have shown one of the shafts extended part way through one of the floats and provided with a power wheel 32, the float beingvformed 4with a pocket 33- in upon by the current of which said wheel. works. This enables the cenere power developed by the motor to be belted parallel guides, and movable projections on f said current boards adapted to move be* tween said parallel guides when drawn outward.
2. A current motor comprising parallel connected floats, sprocket wheel shafts j ournaled on said i'loats, endless sprocket chains running around said shafts, an endless series ot' current boards hingedly connected at one edge to said chains, guides extendingr lengthwise of the floats, pintles on said boards extending beyond the chains and working in said guides, oppositely movable bolts on each current board shift-able into and out of engagement with the guides on the ioats, and a bolt operating lever on sai-d current board, operating to simultaneously move the bolts in opposite directions.
ln testimony whereof' I aliix my signature in presence of two witnesses.
