Specification of Letters Patent.

Patented Jan. 18, 1921.

Application led April 5, 1920. Serial No. 371,535.

To all whom it may 4cof/wem Be it known that I, HUGO A. J. THIESEN, a citizen of the German Republic, residing at St. Louis, State of Missouri, have invented certain new andy useful Improvements in Current-Motors, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings, forming a part hereof.

The present invention is directed to imrovements in current motors, and particuarly to water wheels disposed in the path of a stream of water, although the application of currents of air or ases is not to be eX- eluded. The object 0T the invention is to utilize one or more pairs of wheels mounted on a common shaft, the wheels of any pair rotatin simultaneously irl opposite directions, t e corresponding wheels of an pair (where more than one pair are emp oye'd) rotating in the same direction.` By this arrangement a ymaximum efficiency `is developed from a given current, the construction of the motor is simplified, and its installation rendered easy, all as will more fully appear from the following detailed descril tion of the invention in connection with t Figure 1 represents aside eevation of a portion of a frame in--which the water Wheels are mounted, parts being shown in section; Fig. 2 is a front elevation of Fig. 1; Fig. 3 is a top plan of the wheels shown in Fig. 1, the outer casing being in section.; Fig. 4 is a vertical cross-section through the wheel shaft taken on the line 4-4 of Fig. 5 between the gear hubs of two adjacent wheels; Fig. 5 is a sectional detail through the gear hubs of twoad'acent wheels along a radial lane through t e axis of the wheel shaft; ig, 6 is a front elevation of a frame showing four independent sets of wheels;

and Fig. 7 is a vertical sectional detail show ing the bottom apron leading to thewheel casing... v

Referring ,to the drawings, 1 represents suitable cylindrical codage heid 1o agio position by .a frame composed of' structural menzibersV 2, hereshown' as Lbeams, the frame being built to hold any desired bep ofzoasj'ngs depending on the horse power to be developed. At the bottoni of the frame in' the rear, or on the side facing the current are hinged aprons 3 which serve to direct the current to the bottom casings" and prevent the current from undermining the structure by eddying and washing away the sands. Disposed in the casing 1 at each end thereof (all the casings being alike so that a description vof one will suice for all) is a spiderpro'vided with a central hub 4 and radiating arms 5, the outer ends of the latter being made fast to the inner wall of the casing by angle pieces 6 as shown (Fig. 2). The hubs 4 of the spiders are disposed along the axis of the casing 1 and form bearings for the ends of the wheel shaft S, the front projecting end of the shaft terminating in a bevel gear wheel 7.` Mounted loosely on the shaft S at the center thereof is the hub 8 of the water wheel lV, and keyed to the shaft on either side of the loose wheel WV are the hubs' 9 and 10 of the fast wheels W', W, respectively. The wheels W, W', constitute members of a pair in which provision is `made to cause the loose wheel W to rotate in one direction while the fast wheel W and its s haft S rotate in the opposite direction 1n dlrect response to the current. This pro- `vision is as follows The inner adjacent ends of the hubs 8, 9, are formed with bevel gears or gear rings 11, 11, which mesh with bevel e accompanying drawin sin whichpinions lloosely mounted on studs or spindles 13 extendingin diametrically opiposite directions from `a sleeve 1/1 mounted loosely on the shaft S between the hubs. It

`is apparent from the connections described that when the wheel W keyed to the shaft rotates in one direction, it will impart simultaneous rotation to the loose wheel W in the opposite direction. This reverse direction is assisted by the waters discharged from the wheel W', the current impinging against the blades of the wheel W so as to turn it and the shaft S in one direction, while the waters leaving said wheel impinge against the blades of the loose wheel 'W so as to impart thereto a rotation in the opposite direction, it` being understood that the blades of the two wheels are not only transversely curved in opposite directions but are set at an angle to the planes of rotation of the wheels, those on one wheel being setv reversely to the blades of the adjacent wheel. This causes the current to drive one wheel (W) in one direction, the discharge waters therefrom impinging against the blades of the adjacent wheel (W) so as to drive it or tend to drive it in the opposite direction, this opposite direction being rendered fully responsive to the current by the gearing interposed between the wheels as previously described. rlhe wheel W is fast on the shaft S, the same as the wheel Vil', the blades of the wheel W being set and curved to correspond with the blades oit' the first wheel (lV) so that when the waters discharged from the loose wheel W impinge against the blades of the last wheel (W) they will drive or tend to drive said wheel and the shaft S in the same direction as the wheel lV. Thus, with the foregoing arrangement the maximum eiliciency results from the action of the current, the latter driving the wheels exposed thereto with i'ull force and eiect and consequently driving the shaft S from which the power is taken and distributed to other machinery. In the present embodiment of the invention the bevel gear wheel 7 terminating the front end of the wheel shaft meshes with a horizontal bevel gear l on a vertical shaft 1G, the latter terminating at the top in a bevel gear 17 which in turn engages a vertical gear i8 on the main transmission shaft 19 from which the power may be conducted to any suitable point of consumption not shown. The casings l are secured to the upright structural members of the frame-F by means of plates 20 secured to the outer walls of the casings, said plates being provided with claws or hooks d which engage the flanges of the I- beams constituting such structural members.

Any equivalent means for anchoring the casings to the frame :tall within the scope o l3 my invention.

In F ig. 6 are shown a battery oit lour motors, there being two vertical shaits 1G each driven by a pair of motors, and each shaft contributing its share in driving the shaft 19. The operation is obvious from Figs. l and 3, it being clear that as rotation is imparted to the wheels lV', W, the shaft S will be rotated, and from said shaft the motion is transmitted to the other shafts, the gear connections between the middle loose wheel W, and the iirst wheel lV of the series keyed tothe shaft, making certain that the speed of reverse rotation of said loose wheel is fully commensurate with the speed of rotation of the wheel W, so that the waters discharged from said loose wheel will in turn act on the last wheel W to impart to it a rotation speed commensurate with that of the wheel W. Obviously, the details shown may be considerably altered without involving a departure from either the nature or spirit of the invention. Features shown but not alluded to are well understood in the art and require no description in the present connection.

Having described my invention what I claim is: Y
