WATER Moron. v 5

Application led Apri1p25, 15222. Serial No. 55,'368.

To all whom it may concern:

Be it known that I, lVILLIAM ADELMANN, a' citizen of the UnitedL States, residing'at the city of New York, borough of the Bronx, in the county of Bronx and State of New York, have invented certain new and useful lmprovements in Water'Motors, of which the followingv is a specification.

This invention relates to water power appliances and has particular reference. to a construction including a member adapted to be rotated constantlyA around a horizontal axis by the weight and force of a current of water flowing thereoveror caused to fall upon the side thereof remote from the source of the flow or supply of water.

Vhile I am aware that various types of water wheels have been proposed heretofore, none that have been brought to my attention have possessed the adaptability for erection and operation in any suitable or desired spot in a river or other current of water without the expenditure of a considerable amount of money in the erection of a dam. One of the objects of'theimprovement therefore is to provide a construction of a strong durable nature adapted to be easily built in or along any stream and 4with the necessity for practicallyv no damconstruction except as will be set forth more fully below.

Another object Yof the invention "isto' p rovide' a` watert motor adapted for continuous operation and development of` power`v not only day `and night but throughout 'the `full twelve months of the yearirrespective of the condition of thestream with respectlto ice or 'other materials supported or'floating on the surface of the water. In yother words', one of the chiefobjects of'i'th'e invention is to provide a vwater power mechanism which will 'be of constant adaptabilitvv for power and which will be fool proof, requiring never more than a m'inimumamount'of attention to keep` it in running order.

A still further object of thefinventionl is to provide a water'power plant" so designed as topossess the highest'fpossible percentage of'efiiciency in proportion'to the amount of water iiowing along the stream.`

With the foregoing and other objects in view the invention consistsV infth'e arrangement and combination' of parts hereinafter described an'dclaimed, andwhile the invention is'not restricted'to' the exact details of construction" disclosed or" sugges ted he'reir7 still for the purpose kof.illustrating a .practical .embodiment .thereof .reference-.is 1 hadl 'to` the accompanying drawings,` in whichv like reference' characters designate the same parts in the. several views, and in .whichf- Figure l is a plan View;

F ig. 5 is a plan View indicating` a'modiication.

Referring now more specifically vto the drawings 10 indicates the bed of anyconvenient stream whose normal banks may be understood to be atll. The site for the machine having been determined suitable permanentv buttresses 12 lof concrete, or its equivalent, are erected fromv a suitable depth belowth'e'bed of the stream and along the banks thereof and extending to a suitable elevation, say 'eight or ten feet above the bed of the stream, and extending parallel to the stream. Fitted 'in these buttresses are aY pairof bearings 13 and 14 atan elevation ofsay about four'feet, more or less, and with their. axes' intransverse horizontal alignment; Extendingup the stream as continuations ofv thebuttresses are suitable re taining walls 15 of a height approximating that of the buttresses andcarried substantially' level. along their upperv edges far enough upthe stream to produce a head of water for the operation of Vmy motor. The length of these retaining walls up the stream will naturally depend upon the amount of fall found in the bottom of the stream at the place selected.

Built in or'fsupported in any convenient manner upon or between the buttresses is a girder 16. Thismember extends across the stream between the buttresses and -is made of angle metalor its equivalent with suiiicient stiffness and strength to support the members carried thereby, as fully set forth below, If the stream is suificiently wide thisgirde'r may demand intermediate supports of concrete or the like, but for a span of from ten to fourteen or sixteen feet no intermediate supports are ordinarily necessary;v

A s shown in the main figures the wheel or rotor 17'is composedofv a pluralityof sections 18, each of;- say'fforexample, six

f the girder.

feet in diameter and eight feet in length and comprising a solid core or center 19 and a circular buckets 20. Also each section has closed ends 21 of disk shape. A gudgeon'22 is secured to the center of one end of the lirst section and has bearing in the bearing cup 18. rlhe several sections are secured together end to end by means of fastening members 23 passing through registering holes in the adjacent disks 21. The remote end of the opposite section has connected to its center a power shaft 2a which has bearing` in the bearing sleeve 11i and from which shaft the power may be taken as from a pulley 25 or its equivalent. Thus the rotor will be of unitary construction and substantially integralthroughout and supported only at its ends. lflfhen however the stream is too wide for the rotor to be supported only at its ends l may provide one or more intermediate buttresses 12, as in Fig. 5, and in which auxiliary shafts 24 may be journaled. Otherwise the connections between the parts of the rotor may be the same as above outlined. lt will of course be noted that the buckets 2O on the effective or downstream side of the axis of the rotor are bent upward. By constructing the wheel or rotor of a pluralityV of sections arranged end to end, the several sections may be made of standard lengths or sizes, and for the erection of a motor in any particular' place accor-ding to the width of the stream or the amount of available power, it is expedient to employ and assemble any desired number of such standard sections, a result that is readily accomplished by reason of the construction of the sections, with their own independent sets of blades or buckets and with standard end fastening means.

The girder `16 is provided along its upper y edge with a rabbet 26 in which are received the ends of a series of stringers 27 arranged parallel to one another and resting with their other ends at or upon the bottom of the stream on the up stream side of the machine, the stringers being given an inclination suitable for directing the water ormaterials floating on the water up and over To effect this action I provide transverse planks 28 which may be of heavy oak or other durable species of wood while the stringers may be of metal, such as Lbeams These stringers may easily be put in Vplace and fastened if-desired to the girder and then the planks 28 are put Vin place transversely of the stringers, making a substantially water tight bridge over which the water will flow.

29 indicates an adjustable coping supported at its up stream edge upon or near the top of the girdeiythe upper surface ofthe coping lying substantially flush with.

series of concave blades orY vfor any desirable purpose.

the upper surface of the uppermost plank 2S. Any suit-able means however such as shown at 30 may be arranged to adjust and variably support the free edge of the coping, whereby thel same may be held close to or more remote from the Vtop of the rotor 17. l

`With the deyiceerected as set forth and with the coping adjusted at a suitable level corresponding to the depth ofthe water, the velocity of the current, or otherV local conditions, the water flowing thereover and falling upon the down stream side of the rotor will fill the buckets on such side and the force of the stream and the weight of the water in the buckets will cause a rotaf tion of the rotor as indicated by the arrow. This rotation of the rotor will be continuous, according to the continuity'of the current, day and night an-d throughout the seasons. Any floating materials such as cakes of ice, logs, or the like, will pass over along with the water and will have no other effect upon the rotor than to insure rotation thereof as intended. No lbreakage or other damage to the rotor can result froml such materials. Obviously the power taken off at the pulley or gear wheel 25 may be transmitted to any desired distance and used Because of the continuity of the power the efficiency of the machine will be relatively high even thoughv the power developed in any unit of time may be only moderate, although in most installations the power will be ample for the driving of heavy machinery such as dynamos orother power storing or generating mechanism.
