HOWARD, PENNSYLVANIA.

CURRENT-MOTOR.

Application filed February 15, 1916.

To all autom t may concern? Be it known that I, Cmnnncn C. COOKE, a citizen of the United States, and a resident of Howard, in the county of Center and State of Pennsylvania, have invented a certain new and useful lniprovement in Curthe following is a specification. v

My invention relates generally to current motors, and more particularly to an arrangement the main object of which isv the provision of means whereby to do away with the necessity of transverse dams, and thus enable the erection of the moto1 at any point within a stream without encroacliing upon the riparian rights of others.

ln the accomplishment of this object, it is necessary to provide an endless bucket motor of such a nature as to operate with the an open sluiceway, and particularly one capable of operation in connection with a sluiceway adapted to form part of a longitudinal dam having current deflecting wings extending` upstream and at an angle thereto below the normal water level, so as to permit of the passage of ice and other matter upon the surface of the stream as desired.

The means and mechanism by which these objects are carried out, are shown in the preferred form in the accompanyingdrawings, forming a part of this specification, and wherein- Figure 1 is a plan view illustrating the r arrangement proposed by my invention.

Fig. 2 is a vertical longitudinal section taken therethrough substantially on line 2`2 of Fig. 1.

Fig. 3 is a vertical transverse section taken substantially on line 3-3 of Fig. 2, and

Fig. Ll is a detail perspective view of a portion of the endless member with one of the buckets proposed as a part of my improvenients.

Referring now to these figures, I construct a wall spaced from and bank 11 of whether the bank is high or low, the wall being in upright position with its upper edge well above the high water mark throughout its length. At the upper end of the wall 10 a transverse wall 13 of the height of the said upper wall 10 connects the lat ter with the bank 11 as particularly seen in Fig. 1, and substantially from the angle Spccicatcn of Letters Patent.

parallel to theV a stream 12 irrespective of Patented leba 13, 1917., serial ivo. 7a4-ii.

between the walls 10 and 13 an angular current deflecting wing 1d is extended outwardly into the stream 12 in an upstream direction, this wall being of considerably less height than that o" the walls 10 and 13 as will be seen by reference to the dotted lines in lF ig. 2, so as to terminate some distance below the normal level of water in the stream and thus obviate any material retardation of the flow so as to obviate stoppage of surface matter or. encroachment upon the riparian rights of others along the stream at a lower point.

`djacent the angle between the walls 10 and 13, or in other words, adjacent the outer end of the transverse wall 13, the latter is provided with an opening 15 as best seen in Fig. 2, leading to the the sluiceway 1G formed in connection with the longitudinal wall 10 along' the inner surface thereof, the said opening 15 in the upper end of the sluiceway being at a suitable point below the normal surface of water in the stream 12 to obtain the desired head, and lia-ving its lower end terminating above high water niark.

To this end, after the walls 10 and 13 are constructed, the normal base of the stream iiiclosed by them may be dug out to a considerable extent.

Adjacent the upper and lower ends of the sluiceway 16, are mounted transverse shafts 17 and 18 respectively having pairs of spaced sprocket wheels 19 and 20, the sprocket wheels 2O of the lower shaft 13 being considerably larger than the sprocket wheels 19 of the upper shaft 17. he latter shaft may also be provided with a pulley 21 or other suitable means from which the power developed by the motor may be traiismitted to a suitable point of construction.

Over the sprocket wheels 19 and 20 travel spaced parallel chains 22, the links of which are at spaced points connected by transverse shafts 23 as shown in Figs. 3 and -1 and upon which shafts are loosely journaled extensions 24 at the inner side edges of the buckets 25, the outer side edges of which are connected by links 2G to the chains 22, which links are pivotally united to the parts they connect as just mentioned so as to permit the buckets, though normally held in positions outstanding at right angles to the chains, in their passage between the shafts 17 and 18, to flex as they pass around tho sprocket wheels 19 and 20. The chains 22 may be controlled by a chain tightener 22, as shown in Fig. 2.

It is to be particularly noted that each oi' the buckets 25, open at one side so as to receive therein, the water passing into the upper end oi the sluiceway through opening 15, is provided at its opposite side with a funnel shaped extension 27, the opening 2S of which substantially forms a pressure nozzle through which the current expands into the space between the said buckets and the next preceding bucket, and thence throughout the entire series of buckets within the sluiceway so as to eliminate all dead water between the buckets which would otherwise require the pressure at the bucket adjacent the inlet opening 15 to push the entire series oi' buckets within the sluiceway in addition to turning the shafts 17 and 18.

It will therefore be seen that, due to the particular construction or' the buckets as shown, 1 am enabled to utilize the same to the ends desired within an ordinary sluice way and that due to this Jfact this sluiceway may be erected in connection with a longitudinal wall so as to take full advantage of the head ci water provided by the longitudinal dam construction first above described.

1. A current motor including` a longitudinal dam consisting of a wall parallel to, and spaced from, the bank of a stream and extending above the normal water level thereof, a transverse wall connecting the upper end of the said longitudinal wall with the bank of the stream and having an opening below the normal water level and adjacent the angle between the walls, a wing extending angularly in an upstream direction substanti ally from the angle between said longitudinal and transverse walls i'or the deflection of current into the opening of the latter wall, a sluiceway formed in connection with the longitudinal wall with its upper end adjacent the opening of the transverse wall to receive current therefrom, and having its lower end terminating above high Copies of this patent may be obtained for five cents each, by addressing the water mark, and an endless impulse member operating within and mounted in connection with said sluiceway.

2. A current motor including a longitudinal dam consisting of a wall parallel to, and spaced from, the bank of a stream and extending above the normal water level thereof, a transverse wall connecting the upper end of the said longitudinal wall with the bank of the stream and having an opening below the normal water level and adjacent the angle between the walls, a wing extending angularly in an upstream direction substantially from the angle between said longitudinal and transverse walls for the deiiection of current into the opening of the latter wall, a sluiceway formed in connection with the longitudinal wall with its upper endadjacent. the opening of the transverse wall to receive current therefrom and having its lower end terminating above high water mark, the said vertical and transverse walls extending substantially above the normal water level of the stream and the said wing end substantially below the normal water level of the stream, and an endless power member mounted in connection with the said longitudinal wall and operating within the said sluiceway.

3.1n a current motor of the type described, an endless power member includingV a plurality of buckets open at one side and having at their opposite sides nozzles projecting away 'from the same and establishin communication between opposite sides of the buckets. v

4. 1n a current motor of the type described, an endless flexible power member having outstanding buckets each of which is open at one side and provided at its opposite side with a :tunnel-shaped extension, the aperture oit which communicates with the interior of the bucket, for the purpose described.
