current of water; and to present the greatpossible area to the current of water whereby the maximum degree of power obtainable from the velocity of the flowing water can be obtained; and to provide a new-motor involving a plurality of endless chains carrying a series of adjustable blades against which the current of water in a stream may impinge; and to provide a novel means for adjusting the angular relation of the blades sons to increase or decrease the area of the blades against the stream or current. i

The invention. consists of the parts and the construction and combination of parts,

"as hereinafter more fully described and claimed. having reference to the accompanying drawings, in which Figure 1 1s a plan view in partial sectlon taken on line X-X, Fig. 2. Fig. 2 is an end viewof the motor.

Fig. (3 is a detail View of one of the sprocket wheels advancing screws. Fig.7 is a detail perspective View of a link and joint structure of a blade. Fig. 8 is view of one of the sprocket wheels formed in sections.

One of the particular features of my present current motor is the provision of a power generating element adapted to be entirely submerged and disposed in a line transverse to the direction of the current of a stream of water, and which structure is effective, by the peculiar adjustment of its blades. to derive .power from the current continuously. Maximum efficiency is ob tained in thisRmacliine by, reason of the fact that the planes or blades adapted to be impinged upon 'byfthe flowing stream are at all.

Specification of Letters Patent.

vention I employ a suitable rigid and sub stantial frame structure 2. which maybe erected as the conditions require at suitable points in a stream or current of'waterj and upon the frame structureQ.thre areja'd; justably mounted a pair of carriag 3 formed of a suitable system, of 'bea'ms.

Upun each ot' these carriagesg is journals-d 3 a transverse shaft at disposed endwiseto the current of the water in the stream.

respective stationary frames 2 according to the variations of the elevation of thewater in the stream. Any suitable means may be employed for vertically adjusting the' carriages 3, and in the present instance I'li'ave shown vertical screws 5 extending upwardly through the stationary frames 2 and provided with suitable wheels (tat theirupper portion whereby the screws may be turned to lift or depress the carriages in the ends of which the screws engage suitablethreaded bearings 7. Uponeach of the'shafts iare secured threaded sleeves 8 arranged at suitable distances from each othergan'd upon each of the screws on the shafts 4 are moun'ted sprocket wheels 9 arranged in pairs upon the shafts 4:. The sprocket wheels?) on the parallel shafts 4 areso adjusted that they will properlyaline with each other. Upon the alined sprocket wheels 9 there are mounted parallel sprocket chainslO and 11. which are thus presented transversely to the flow of the stream. 1'

The sprocket chains 10 and 11 are each composed of a plurality of links. upon su' able ones of which. as 12. are provided p. ots 13. upon which are mounted suitable blocks 14 carrying pivots 15 adapted to 'sup port the shorter ends of blades 16. These blades 16 maybe of any desirable numberia's determined by the distance'between the par allel shafts 4, and since their ends are connected. as at 13. to the parallel chains 10 and 11, the blades are first carried transversely across the stream above the plane of,

whereby the angi'ilarity o1 the" blades' 16 may be nicely adjusted as thevelocity of'the flow of the water may require, and by which means the blades .16 may be brought into parallelism with'the direction of flow of the stream. This means for accomplishing the adjustment or angular position of the several blades 16 comprises a series of spiders 17, one of which is firmly secured upon the shafts 4 on the outside of each 4915 the sprocket Wheels 9, which, as before stated, are turnably supported uponftheir respective screws 8. Each of the spidersl? carry a number of levers 18, fulcrumed at 19 upon the radial arms of the spiders, the shorter arms .of the levers 18 being connected by links 20 to suitable pivots21 upon the adjacent sides of the sprocket wheels 9.

The longer arms of the levers 18 are connected, as at 22, to the outer ends of links 23, which are pivoted at 24. upon the flanged I end of sleeves 25 reciprocably keyed upon each shaft 4. These sleeves 25 are each provided with transverse threaded extensions 26 mounted upon parallel screws 27 journaled in convenient members of the carriages 3. The sleeves 25 are turnably mounted within the members 26 but are moved longitudinally by the same when the screws 27 are rotated by means of gears 28 fastened on their ends and which mesh with master gears 29 loosely supported adjacent the ends of the power shafts 4. I

The master gears 29 may be provided upon one side, as 30, with gear teeth meshing with pinions 31 secured upon the lower ends of, vertical shafts 32, having splined on their upper ends sprocket wheels 33 by'which power is conveyed from one shaft 32 in one of the frames 2 to the other shaft 32 in--the or equivalent means 34. Upon each of the actuating shafts 32 at one end of each carriage 3 is mounted a bevel gear 35 meshing with a corresponding gear 36 which is secured upon a transverse shaft 37, one of which is mounted upon the upper portion of each. carriage 3. Upon the other'end of each shaft 37 is provided a fixed gear 38 meshing with a gear 39 secured upon the uppera'end of short actuating shafts 40by which power is transmitted from the actuating shaft 32 to operate the screw driving gear 29' loosely mounted on the opposite end of the shaft on which is mounted the gear-29, In operation when one of the vertical shafts 32 is operated, motion is transmitted to the several master gears 29 and 29 loosely mounted adjacent the ends of the shafts 4, and these gears 29 and 29 actuate the screws 27 which cause the advance or retraction .of the transverse blocks 26 turnably-engaging.

and reciprocably moving their respective sleeves 25. When the sleeves 25 are drawn away from each other by their screws 27,

the links 23 pull on the long arms of the levers 18 and swing the shorter arms of the same toward each other so that the links 20 tend to rotate their respective sprocketupper end a transmitting gear 44.

wheels 9 upon their supporting screws 8,

which rotation 'of 'thewheels 9 relatively to the shafts 4 cause a'change of angle of the reason that the sprocket wheels 9 are turnable upon their shafts, and by reason of the screws 8 may advance toward each other to allow the blades 16 to adjust themselves angularly between the parallel sprocket chains 10 and 11. The pitch of the screws 8 is such that when the levers 18 are actuated the several sprocket wheels 9-turn upon their shafts in a reverse direction so that one of the sprocket wheels moves to advance its chain forwardly and the other sprocket wheel carries its chaln rearwardly simultaneously moving the chains toward each other. \Vhenthe operator has'adjusted the blades 16 in such angular relationas he may determine best suitsthe velocity of the stream or which will produce the power desired, the entire system of traveling blades and their supporting sprockets being submerged,

' the power of the moving current is exerted againstall of the blades irrespective of the direction of their travel by reason of the fact that all of the blades present a plane of angular resistance to the current of water which is constantly effective to drive the blades 16 in a continuous, endless orbit; thus all of the blades, when angularly-disposed to the direction of the current, do work,

Power may be taken from either or botl of the shafts 4 by any suitable form of transmission mechanism, and this is indicated inone form" by a gear 41 meshing with a gear 42 fixed upon the lower end of a transmission shaft 43 journaled at its lower end in one of the carriages 3. and having splined upon its In Fig. 8 I have shown one of the sprocket wheels as being built up of a number of sections 9'. This may be any desirable form of wheel when the apparatus is erected on a very large scale or when one of the motors is going to be erected in a mountainous country and an integral sprocket wheel would be too massive for convenient transportation. c
