IPIBOPIET.'LERk 0F MACHINERY TO BE 'USED IN CURRFEN'JLS.y

Specication of Letters Patent No. 8,525, dated November 18, 1851 Fig. 2 is a Ysponding parts in each of the figures.

The nature of my invention consists in attaching one or more levers at about their centers to a suitable frame overhanging a river or stream, said frame being properly secured on the bank, in any suitable way, the levers are attached to the frame by universal joints. To the outer ends of the levers floats or blades are attached against which the current acts in a manner which will be hereafter described.

The frame above mentioned is hung upon pivots so that it may be raised or lowered by a windlass or otherwise, and the floats or blades of the levers be at all times properly submerged in the stream. The other or inner ends of the levers are attached to cranks or connected'with toothed wheels in such a manner that power may be applied to any machine designed to be operated.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

` A A represents the levers, and B B the floats or blades attached to the outer ends.

C C are the universal oints by which the levers are attached to the cross piece (a) on the end of the frame D, these universal joints are of ordinary construction and will be readily understood by the following description. Each lever A sets between two plates (b) (b). These plates extend up on the sides of the levers and are united under the lever forming a sort of clasp. A hole is drilled through the plates and lever, through which a bolt (c) passes. They are thus allowed to vibrate vertically. A rod (cl) is attached to the plate underneath the lever and projects downward into the cross piece (a) of the frame D and the levers are thus allowed to vibrate horizontally.

(e) (e) are pivots on which the frame D is hung loosely and it will be seen by the drawings that the frame D is hung to an outer or stationary frame E which is to be vfirmly attached to the shoreor banks of the stream which is represented by I-I. On this stationary frame E is placed the windlass F around which ropes or- -chains G pass that are attached to the movable frame D and by this means the frame D is raised or lowered as the height of the stream varies and the floats or blades B B at all times properly submerged.

I, I, are cranks to which the ends of the levers A A are attached, pins (f) (7) on the levers passing through the ends of the cranks as seen more particularly in Fig. 2. These cranks are attached to and form part of the shafts J, J, to the ends of which the toot-hed wheels K K are affixed. The shafts J, J, have their bearings on the cross pieces nd other parts of the frame D, as seen in L, L, are pinions hung on the shaft M, said pinions meshing into the toothed wheels K, K.

N, is a fly wheel also attached to the shaft M.

It will be seen that the gearing just described as well as the levers are all attached to and move with the frame D, when it is raised or lowered.

The operation is simple. The frame D is properly adjusted by means of the windlass F and the floats or blades B, B, submerged. Fig. l shows about the position ofthe frame D and levers A A when the nachine is ready for operation, the dotted line X X representing the water line. We will suppose the current of a river running in the direction indicated by the arrow fig. 2, it acts upon the blade of the lever A till the crank I is brought around to the position shown by the dotted lines making half a revolution, the current then acts upon the blade of the lever A which also makes half a revolution and brings back the lever A above the surface of the water to its original position ready to be again acted upon by the current, it will be seen that the fly wheel N is necessary to carry the cranks past their centers, and if one lever is only used the fly wheel by its momentum would throw the lever back the half revolution of the crank after being moved forward by the current. The shafts J J and toothed wheels K K being made to revolve by the alternate motion of the levers A A a continuous motion is given to the shaft M as Will be readily seen, and power may be applied from it to any machine.

I do not conine myself to the exact mode of gearing herein described as many modifications of the same may be used and answer equally Well. But

Vhat I claiml as my invention and desire to secure by Letters Patent is-` The application for the purpose specified of one or more levers A A With the floats or blades B B at their lower-ends against which the current acts, said levels being attached at about their centers to an adjustable frame D by an universal joint C as described, the upper ends of the levers being attached to cranks I, I, by which, through any suitable gearing motion is communicated to the shaft M substantially as clescribed.
