WATER MOTOR 2 Sheets-Sheet 2 Filed Feb. 7, 1929 l l l zl'wuemtov Bad F2 0/272- Z'e dttomwq Patented Nov. 4, 1930 FRED, FACI-INIE, F wrrn'now, WASHINGTON WATER Moron '1 Application fil ed February 7, 1929. s r a l q- 333 19? l This invention relates to Water motors, and more particularly to a water motor intended for operation by the current of a running stream.
' An important object of the invention is to provide adevice of this character which may be readily and cheaply manufactured and which will provide an efficient and durable motor structure delivering a smooth even power driveat a desired point.
A further object ofthe invention is to provide a device of this character where the construction issuchthat the blades are always assured of proper submergence and 1 means are provided for preventing accidental I disengagement of these blades with the bot tom of the stream.
These and other objects I attain by the construction shown in the accompanying draw-- 539 ings, wherein for the purpose of illustration p p p p a from a right angle being such that the entire series of blades is uniformly spaced about is shown a preferredembodime nt of my i11- vention and where1n:
Figure 1 1s a side elevation of a water motor constructed in accordance with my invention; t
Figure 2 1s a sectional view therethrough;
Figure 3 is a sectional view through the v v H I a I p I turbed to an extent that the si'derslip propeller shaft;
3 Figure 4 is a longitudinal. sectional view '8 through the propeller shaft showing the means of securing the blades in position thereon. 1 Referring now drawings, the numeral 10 generally designates a raft, which is preferably in the form 'of'parallel pontoon elements 11 connected adjacent their forward and rear ends by braces 12, which maintain-the elements in a predetermined spaced relation. The forward ends o-f these elements will be-provided with i any suitable: means to permitthe raft to be secured to anchors orthe bank of a stream, as
' desired. Extending downwardly froml-the pontoon elements adjacent the forward and rear ends thereof are convergent braces'13, the lowerends of, which have secured thereto bearings 14: withinwhich operate a horizontal shaft 15.- The forward bearing 14 is pref-1' erably connected with the pontoon elements; f by upwardly and. forwardly incl ning braces,
v hereinafter more particularly to the this character may bevery readily manufac v 'Inorder to insurethe blades against c'on-' indicated at'Tl5; The forward end of the, shaft is con'nectedin any suitable manner as, for example, by chain and sprocket gearing illustratedat 16 with ashaft 17 mounted I in bearings 18 carried by the forwa rd.braces. 12. ,Thi'sshaftgl7 is at present illustrated as having a' pulley 18 attached thereto and is referred to as a'power take-off shaft. to f j L Secured'to the ,shaftjare a plurality of blades"19, these"bla desbeing uniformly. spaced along the shaft between the bearings andeach comprising a straight strip ofmaterial, the, central portion 20 of which per; p'e'ndicularly ,relatedifto I the shaft and the eiid'portions 21 of which areoppositely flexed ortwis'ted toplace them at'an angle of between 51v and 10 to such central portion.
i Adjacent blades aredisposed at substantially right "anglessto one another, the, variation of'the current against thebladegdoesfnot interfere with:properfaction of'the current 0" upon the next succeeding blade and by em ploying a small angle or pitch for thebl'ad'e'," ti iefthrust' obtainable is increased and the operation-of the shaft steadied: Bladesiof tured' and in event anything comes in 'con- .ta ct therewith causing th'eblade tobecome bent, maybe very readily straightened.
tactlwith the bottom-the stream, due" to reduction in the' level .jthereof, I secure toopposite ends of theponto'onsi rigid leglele-v inents' 22; the lower ends of which: are arranged in a plane paralleling-the p'ontoonsi and ,belowthe path movement i'of the blades; [These legs, in "ever rt the stream low? ,ers to a predetermined extent, -willengag fe t upon the"bottom thereof, supporting the ontoons-and thuspreventthe blades from beingfidamagedi Since the' blades' are aii blades and the sprocket to the shaft 15, this shaft is made composite, comprising an inner rod 22 surrounded by a series of sleeve elements 23. Nuts 24 at opposite ends of the rod serve as a means for compacting the sleeve elements and causing them to grip Washers 25 disposed at opposite sides of the sprocket of the shaft and at opposite sides of the various blade elements.
Each blade element is formed with a central. opening 26 for the passage of the rod 22. This structure further facilitates maintenance of the shaft against longitudinal movement,,as certain of the sleeve elements which extend through the bearings 14 may be made of the same length as the width of these bearings and washers 27 disposed at opposite ends thereof which are of greater diameter than the bearing and which accordingly engage opposite end faces of the bearing to hold the shaftsin its proper position. This structure not only maintains the shaft against movement but provides a structure wherein any of the elements may be very readily replaced and the sleeves which ac-s tually form the wearing surface coacting with the bearings may be readily replaced in event any loosene ss occurs at this point.
Since the construction hereinbefore set forth is capable of a certain range of change and modification without materially departing from the spirit of the-invention, I do not limit myself thereto except as hereinafter claimed.
I claim A water motor of the character described comprising in combination, a pair of pontcons, a pair of bearings dependingly secured to saide'p ontoons and adapted to be 7 positioned in a stream of running water, a Vshaft loosely mounted 1n said bearings, a. sleeve posit oned about said shaft and en gaging said bearings, said sleeve comprising signature.
