SUBMERGED WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 707,857, dated August 26, 1902.

Application filed April 21, 1900. Serial No. 13,802. (No model.)

To aZZ whom, it may concern:

Be it known that I, GUSTAV MARBURG, a subject of the Emperor of Austria-Hungary,

residing at Vienna, Austria-Hungary, have,

water-wheel is divided in the middle and the two halves are capable of being sprung apart, so that they will lie in a direction parallel with the banks of the river or stream.

In order to render the present specification easily intelligible, reference is had to the accompanying drawings, in which similar letters of reference denote similar parts throughout the several views.

Figure 1 is an elevation, partly in section, of a water-wheel constructed according to the present invention. Fig. 2 is a sectional plan on the line A B of Fig. 1, showing the coupling of the two wheel parts at the center or thereabout of the stream; and Fig. 3 is a side elevation of one-half of a modified form of water-wheel.

The water-wheel consistsof the two vertically-divided parts a and b,having stub-shafts 7c at one end of each half, by means of which the said half is mounted to rotate in verticallyadjustable bearings m an d n of any suitable or well-known construction. These bearings are mounted, respectively, on the verticallydisposed standards 6 and 71, arranged one at each side of the stream or river, and the said bearings m and a may be vertically adjusted on the said standards in any suitable manner. For instance, the bearings may be suspended on lines or chains (indicated by d0t ted lines 6) and capable of being raised or lowered by means of the winches 6 mounted at the top of the standards. The standard 6 has a lower roll f, adapted to move on the foot-plate g in the arc of a circle the center of which is the vertically-disposed powertransmitting shaft 0, and the stub-shaft 7c of the wheel-half a carries behind the standard a a bevel-gear engaging a similar gear on the power-transmitting shaft 0, which is coupled at its upper end to the power-shaft d by means of bevel or chain or other suitable gearing. The bevel-gears of the water-wheel shaft and the vertical shaft 0 are retained in engagement when the water-wheel is swung around by means of a yoke m. The standard 7:. simply turns on its lower pivot, which is mounted in the foot-plate 11 and free to turn therein. The water-wheel halves are covered by a half-mantle p p, the two halves of which may be connected together by a latch-lever s, Fig; 2, which serves to make one rigid structure of the two half-mantles, but permits of their separate removal. These mantles inclose the upper part of the waterwheels, so that the motion of the current will only act on the lower parts of the same in one direction to cause them to turn; otherwise they would stand still or simply swing on their stub-shafts, as will be readily understood. The latch 3 must be of suiflcient strength to resist the force of the current. The ends of the waterwheel halves are coupled by a set of flanges q and 1', Figs. 1 and 2, which engage one within the other, the coupling-latch s of the mantles p preventing the disengagement or swinging apart of the coupling-flanges q and 1* when in the horizontal position during rotation. The interior ends of the wheel may be supported by floats or buoys 0 0, several of which may be employed, if necessary. Instead of the floats or buoys the-mantle 19 might be made with will thus turn around on their guide-standdescribed with reference to Fig. 1.

ards e and h and lie along the banks of the river or stream, so that the vessel or other body may pass between them. When this has taken place, the wheel-halves are swung back, either by means of chains or any other suitable means, the flanges will pass into engagement again,and the mantle-halvesp must then be recoupled by means of the latch-lever 8. The wheel-halves may also be pulled apart by means of chains or other suitable means.

The modification of the device shown in Fig. 3 enables thewheel to be employed for streams or rivers of different widths, the blades of each half of the wheel being adapted to telescope oneinto the other, the said blades being normally retained in position by means of fixed intermediate disks. Any suitable joints may be employed for the ends of the wings, such as shown at it in Fig. 3. For instance, the ends of one set of blades may pass into sockets at the ends of the other set and the wheels may be telescoped together when it is required to employ the same with narrow waters. These wheels may be mounted and controlled in a similar manner to those As shown in the drawings, the blades are spirally turned in order to render them more efficacious.

I claim as my invention- 1. The combination of a submerged waterwheel vertically divided in the middle and means for allowing the two parts of the same to swing apart substantially as described.

2. The combination of a water-wheel divided into two parts vertically, ahorizontallydisposed stub-shaft to support each part of the same at the outer end, means for coupling the two parts togetherand means for allowing the supporting-shafts to swing apart in the horizontal plane and separate the two wheel parts substantially as described.

3. The combination of a Water-Wheel divided into two parts, means for supporting each part of the same at the outer end and floats to sustain the inner ends of the same, a coupling to connect the two parts at their adjacent ends and means for allowing the two parts to swing apart horizontally in the manner and for the purpose substantially as described.

4. The combination of a water-wheel consisting of two parts, means for coupling the two parts at their adjacent ends, stub-shafts at the outer ends one to carry each wheelhalf, vertically-adjustable bearings for the said stub-shafts in the manner and for the purpose substantially as described.

5. The combination of a water-wheel consisting of two parts, means for supporting each part rotatably at its outer end, a coupling to couple the said parts at their adjacent ends and means for adjusting the length of each part to suit currents of different breadths substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

GUSTAV MARBURG.
