WATER-POWER WHEEL.

SPECIFICATION forming part of Letters Patent No. 447,810, dated March 10, 1891.

Application iilecl J'une 17, 1890. Serial No. 355,766.A (No model.)

To @ZZ whom t may concern:

Be it known that we, JOHN DAHLQUIs'r, a citizen of the United States, residing near Portland, in the county of Multnomah, State of Oregon, and OLoF N. DAHLQUIsr, a citizen of the United States, residing at Tucker, in the county of Oowlitz and State of Tashington, have invented certain new and useful Improvements in \Vater-Power Wheels; and we do hereby declare 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.

Our invention relates to water-power wheels adapted to run in any stream of running water and to be operated by the natural current of the stream.

The object of our invention is to produce a water-power wheel having a series of paddles pivotally secured in a suitable frame, and a mechanism to throw the paddles out of working position, the whole being placed and secured in a frame having slotted standards, which are secured between two piles, thus enabling the whole frame to be lifted bodily out of the water for repairs, dto.

By the mechanism above mentioned the wheel can be stopped without taking it out of the water; and with these ends in view our invention consists in the parts and combination of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure l is a vertical central section through the wheel and supporting-frame. Fig. 2 is a longitudinal central section through the same. Fig. 3 is a side elevation of the short locking-rod. Fig. 4 is a side elevation of the long lockingrod.

A represents the top and bottom of the su pporting-frame 5 B, the side pieces thereof. The said side pieces B are eachprovided with a groove b, by means of which the frame can be slid down and be secured between two piles, (not shown,) and can be readily hoisted out of the water when necessary.

O is a shaft having bearings in the top and bottom pieces A of the frame. Around the shaft C are secured circular plates D, between which are secured arms D', connected at their outer extremities by means of circular bands d. These circular bands dare connected with each other by means of standards d', to which are hinged the paddles E and F. These paddles E and F, constituting an upper and lower series of paddles, are arranged alternately with respect to each other. The paddles are provided with projections e and f, respectively. The circular plates D are slotted around the shaft O, and above' the upper circular plate D is a sleeve G, havingv extensions g and g', the said extension'g resting directly upon the plate D. This extension g is slotted like the plates D.

H is a locking-rod, which is passed through the slots in the extension g and some of the plates D and serves to lock the upper series of paddles E. This rod H is provided with notches h.

H is another locking-rod, which extends through the slots in extension g and all of the plates D and serves to lock the lower series of paddles F. This rod H is provided with notches h.

Pivoted to one of the side pieces B at 7l is a cross-beam I, having a central aperture, by means-of which it is secured loosely around shaftI O. The sleeve G extends up through this cross-piece I and is secured to it by means of the extension g', which rests directly on the cross-beam. The other end of this cross-beam I works in a slot or opening` B in the other side piece B.

Secured to the beam I is a staple t", to which is connected a rod i, working` in an opening A in the top of the frame.

The operation of our Water-power Wheel is as follows: The piles hereinbefore referred to, but not shown, are iirst secured in the stream in which it is desired to place the wheel, the wheel being secured in the frame as described. The frame is then slid down between `the piles and is held in position between them by means of the grooves b in the side pieces B. The paddles on one side of the wheel are, by means of the projections e and f, resting against the y up side 7 ofv the locking-rods H and I-l, or, in other words, against the side of the locking-rodsv toward which the current is running. The current now starts the wheel and bears against each IOO and every paddle in its turn until the paddle gets parallel with the current, the wheel still revolving. The current of the stream then throws the paddle that is parallel with it out of place and swings it out, so that it offers no ,resistance to the current and passes up edgewise against the current. It will be readily understood that the current acts only on the paddles on one side of the wheel, and those on the opposite side pass up edgewise against the current. This action being kept up by the current, the wheel will give a power sufficient to run any desired machinery. It is obvious that the wheel may be connected to the machinery which it is desired to operate in any suitable manner. W`hen it is desired to stop the wheel, the rod i is pulled up, which in turn raises the cross-beam I and sleeve G by means of extension g. This raises the locking-bars II and H', thus bringing the notches 7L and h directly behind the projections c and f, respectively, thus taking away the support of said projection. The paddles, having no support, swing edgewise with the current, thus offering no resistance. Consequently the wheel stops. When it is desired to start the wheel again, the rod is lowered, thus lowering the locking-rods II and Il. Thus the notches 7L and it are let down below the projections e and f, and the projections again bear against the rod. The current will again revolve the wheel, as above set forth. It will be understood that the lifting-rod i may be connected with any suitable gearing for lifting.

It is evident that many slight changes and alterations may be made in the relative construction and arrangement of parts without departing from the spirit of our invention. Hence we would have it understood that we do not confine ourselves strictly to the parts herein described.

Having fully described our invention, what we claim, and desire to secure by Letters Patent, is-

l. The combination, with the series of paddles having lugs on their inner ends, of the sleeve having extensions, one of which is slotted, the locking-rods provided with notches, and the cross-beam suitably connected to a lifting-rod, substantially as described.

2. In a water-wheel, the sleeve having extensions, one of said extensions being slotted, the alternate long and short locking-rods having notches, the cross-beam connected to the sleeve and a suitable lifting-rod, and an upper and lower series of paddles having lugs or projections, the whole secured and operating in a suitable frame, substantially as described.

3. In a water-wheel, the frame, a cross-beam pivotally secured to said frame and connected to a lifting-rod', the sleeve having extensions, one of which is slotted, the said sleeve working around a shaft and secured to the crossbearn, the long and short locking-rods having notches, and the upper and lower series of paddles provided with lugs or projections which engage 'the locking-rods, substantially as described. D

4. The combination, in a water-wheel, with a frame having grooved side pieces. the shaft C, the cross-beam pivoted to one of the side pieces of said frame, a lifting-rod secured to said beam, the sleeve G, having extensions g and g', the extension g being slotted, the alternate long and short locking-rods having notches, the slotted plates D, between' which the arms D are Secured, a vertical standard d and ring CZ, connecting the arms D', and the paddles having projections engaging the locking-rods, the said paddles being hinged to the standards el', substantial] y as described.

In testimony whereof we affix our signatures in presence of two witnesses.
