' WATER-WHEEL.

Specification of Letters Patent.

Patented Oct. 4., 1921.

Application filed August 30, 1920. Serial No. 406,810.

To all whom it may concern Be it known that I, JOHN KING, a citizen of the United States, residing at Williams Lake, British Columbia, Canada, have invented certain new and useful Improvements in \Vat-ei Wheels; and I do hereby de- Clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

, This invention relates to water wheels. and aims to provide a power apparatus of that character comprising a novel and improved construction.

'One of the objects is the provision of a water wheel rotating about a vertical or substantially vertical axis.

Another object is the provision of a water wheel of that character whose blades are movable vertically, with novel means for mounting the blades and for lowering them into the water and raising them out of the water at the proper time.

A further object is the provision of supplementary or extension blades for the main blades, and novel meansfor mounting said supplementary blades from the main ones to enable the supplementary blades to fold or swing back when raised out of the water.

lVith the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides inthe 7 construction and arrangement of parts hereinafter described and claimed, it being understood that changes'can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, where n:

Figure 1 1s a plan view of the improved water wheel, portions being broken away.

Fig. 2 is a diametrical section thereof, portions being broken away and portions shown in elevation. I

' Fig. 8 is a vertical section of one of the standards for the blade arms.

Fig. 4 is a plan view showing a pair of blades with the supplementary blade swung back. i

Fig. 5 is an elevation showing a pair of blades as when in the water.

In carrying out the invention, a vertical or substantially vertical shaft 10 is mounted. on a float or foundation 11 disposed in the stream at any suitable point thereof, and the lower end of the shaft 10 is journaled in a step bearing 12 secured on the float 11. A wheel 13 is secured to the shaft near the lower end thereof, and has an annular series of gear teeth 14; meshing with a pinion 15 secured on ahorizontal shaft 16 journaled in bearings 17 mounted on the float 11,-whereby to transmit the motion from the shaft 10 and wheel 13 to the shaft 16. This shaft preferably has a clutch 18 for opening and closing the connection between the water wheel and a pump or other machine operated by said wheel.

The wheel 14 is maintained in its plane of rotation by means of rollers 19 above and below the rim or marginal flange of said wheel 13, and carriedby brackets 20 secured on the float 11. This will prevent the shaft 10 and wheel 13 from tilting, and will enable the water wheel to-rotate freely about the axis of said shaft.

Vertically spaced hubs 21 are secured on the shaft 10, by means of set screws 21' or the like, which permit said hubs or disks to be adjusted vertically, and radial arms 22 having the blades 23 at their outer ends, are hinged at their inner ends to the hubs 21. As shown, there are three hubs 21 and several sets of arms 22 and blades 23, with three in each set, and the blades 23 of eachset are spaced vertically to be submerged in the water to different depths, as seen in Fig. 2, with the blades disposed in different vertically planes radially of the wheel. The arms 22 being hinged to the hubs 21 can swing vertically for raising and lowering the blades, and rollers 24 are mounted in brackets 25 secured to the arms 22 to travel on an arcuate track 26 mounted on the float 11, with the end portions of the track sloping downwardlyl/Vhen the arms 22 are between the ends of the track 26 at one side of the float 11, said arms can swing downwardly to submerge the blades 23, whereby the current will move said blades (in the direction of the arrow in Fig. l) to rotate the wheel, and as the rollers 24 contact with the corresponding end of the track and roll onto same, the arms 22 will be raised to elevate the blades out of the water.

In order to limit the depth to which the blades are submerged in the water, slotted and are stepped or offset as seen in Fig. 3, so that the arms 22 of each set pass through the corresponding standard. These standards guide the arms 22 for vertical movement, and carry stops 28 for limiting the downward movement of the arms when the blades are submerged. The stops 28, .as shown, are inserted in apertures 29 in the standard, and can be adjusted vertically, to regulate the )osition of the blades 23 when submerged. he hubs 21 can also be adjusted vertically, to re ulate the positions of the arms 22 when submerged and raised, so that adjustments can be'made to suit the conditions by adjusting the hubs 21 on the shaft 10 and adjusting the stops 29 on the standards 27.

In order to takeup the strains from'the arms 22, inclined arms 30 are hinged to a hub or disk 31 secured on the shaft 10 be low'the hubs 21 and above the wheel 13, and the upper free ends of said arms 30 are connected by a chain 32 or other flexible element, and said chain 32 and arms 30 are connected by stay chains 33 to the wheel 13. The chain 32 is connected by stay chains 34 with the arms 22, whereby the pressure against the blades or addles 23 is transmitted partially to the chains 34 and 33, thereby preventing said arms from bending or breaking. Said chains enable the arms 22 to swing upwardly without interference, and the arms 30 can also swing upwardly if necessary. 7 r i In order to increase the power, supplementary or extension blades 35 are used, being hinged to the outer ends of the arms 22 and blades 23, as at 36, so that the blades 35 can swing rearwardly into folded position, as seen in Fig. 4. brace 37 is hinged at one end to each blade 35, as at 33, and is pivotally connected at its other end to a slide 39 movable along a bar 40 secured to the corresponding blade 23in rear thereof. Thus, when the blade 35 swings rearwardly in being raised out of the water, itpushes the brace 37 so that the slide 39 slides inwardly on the bar l0, and when the blades enter the water, the pressure of the water against the blade 35 will swing same forwardly into alinement with the blade 23, thereby pullin the brace 37' and slide 39 until the slide 39 strikes the outer end of the bar 40, thereby limiting the movement of the blade 35.

It is preferable to provide a float 41 on the upper edge of each blade 35, having sufiici'ent buoyancy to counterbalance the weight of the blade 35, thereby avoiding abnormal strain by gravity on the arms 22 when the blades 35 are extended and sub-' merged in the water.

In operation, the rollers 24; in riding on the track 26 will support the arms 22 in raised position, and as they move off of the track, the arms will swing downwardly by oravity, thereby lowering the blades into the water vertically. The blades are thus submerged at one side, and the current of the water will thereby rotate the wheel, and as the blades complete an arc of movement in the water, they are raised out of the water again by the contact of the rollers 2lwith the opposite end of the track 26. As the blades 23 are raised out of the water, the supplementary or extension blades 35 swing back, and when the blades enterthe water again, the blades 35 are swung into operative position by the pressure of the water against same. The blades 35 being swung inwardly when raised, will lessen the strain on the arms 22 and other parts of the wheel owmg to leverage. The power derived from the wheel can be used for operatin a pump or other machine." (Not shown). i f
