Specification of Letters Patent.
Patented Dec. 6, 1921.
Application filed January 9, 1919. Serial No. 270,283.
To all whom it may concern:
Be it known that l, Orr-ii L. flows, of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in ater-Motors; and 1 do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.
The object of my invention is to provide an improved type of water motor, comprising a frame suspended on a track above the stream of water and on which frame is a supporting beam for the cradle of the vane carrier, the support and the cradle being capable of being raised so as to lift the vane carrier from the current, the carrier being so arranged on the cradle that it may be swung horizontally in the event of undue pressure created either by heavy currents or by the normal current and flotsam.
. In the accompanying drawings, Figure 1 is a view in side elevation. Fig. 2 is a view at right angles to Fig. 1, parts being in section. Fig. 3 i a top plan view and Figs. at and 5 illustrate a slight modification of the means for suspending the frame.
In the drawings, 1 designates a vertically disposed frame which is suspended on elevated ways 2 appropriately positioned between uprights arranged on opposite banks of astream. A swinging beam 4 is carried by the frame 1 and may be secured thereto at any one of several elevations by a cross rod 5 which serves as a pivot for the beam. The latter is of rectangular form and is provided with a centrally and longitudinally disposed track 6 over which travels a suspended balancing weight The position of this weight on the beam is controlled by guiding ropes 8 and 9 which travel, re spectively, over pulleys 10 and 11, the ropes being connected with the weight and after passing around these pulleys they are carried up over appropriately journaled heaves on the frame 1 and uprights 3, and then to any convenient point adjacent one of the supporting uprights 3 where theymay be controlled for moving the weight 7 along its track. It will be apparent, see Fig. 2, that a pull on rope 9, with the rope 8 loose, will draw weight 7 to the upwardly extending end of the beam 4.
A vertically disposed rectangular frame 20, with its uprights indicated at 21, forms a cradle for a vane carrier to be later decribed. The connection between the cradle and the beam is such as to insure an anprorh mately vertical movement of the cradle in the up and down movements of the beam. The arms 21 are provided with a series of spaced apart apertures permitting adjust ment of the cradle on the beam various heights. Extending centrally of the cradle and supported thereby is a rod 2% which forms a pivot for a horizontally disposed bar 25 c0nst1tuting a vane carrier, this bar being suitably braced by cables 26, guyed to the cradle. A platform 22 is a partof the vane carrier and is connected with an held in spaced relation to the part 25 by uprights 26" so as to insure a turning of the platform in the turning movement of the vane carrier, the platform forming a support for a pump 23. Preferably the vane carrier ar ranged so that a greater portion of its leugt is at one side of the pivot, see Figs. 1 an? 2,. 27 deslgnates a series of vanes journaed on the vane carrier and appropriately geared to convey power to the pump the l t having suitable land connections. In ore that the vane carrler may be maintained in position against the current I provide a weight 28 which is suspended from a cable 29 passing over a sheave on the frame 1, the other end of the cable being connected with the vane carrier. The power of this weight is just sufficient to maintain the vane carrier in position across the streams for the normal current of the latter and if excessive currents appear the carrier will swing about its vertical pivot on the cradle. The gathering of flotsam about the vanes or the carrier which would create extraordinary pressure is suflicient to overcome the power of the weight and move the carrier so that the vanes will be ineffective. To prevent swinging of the cradle about its pivotal connection with the beam chains 30 are connected to the arms 21 and the vertically disposed frame 1. This chain also aids in maintaining the desired angularity between the cradle and beam as well as between the beam and the frame.
The use of my improved motor will be apparent. It is readily suspended, and the depth of the vanes in the current regulated either by elevation of the supporting beam by changing its point of connection with the frame, or by tilting the beam so as to slightly raise the cradle, the latter being effected by a movement of the balancing weight 7. When it is desired to remove the cradle from the stream, manipulation of the rope 9 will efiect movement of the weight 7 along the track 6 to the end of the beam opposite that which carries the cradle. This lessens the Weight on the cradle end of the beam and enables the beam to be more readily turned about its pivot by pulling on a rope31,'power being applied by any preferred means, not shown. Before the parts are elevated, asdescribed, it is advisable to turn the vane carrier about its pivot. This is readily effected in any preferred manner.
In Fig. 4 I have shown a derrick from which the frame 1 is suspended where it is impracticable to have a way stretched from one bank of a stream to the other. 35 designates a mast or post from which a swinging boom 36 is appropriately suspended, the frame 1 supporting the cradle and vane carrier, both of a like construction to the same parts shown in Figs. 1, 2 and 3, being secured to the boom. For the purpose of controlling the position of the vane carrier in the stream, a weight 37 is provided, the cable 38 to which the weight is attached passing over a sheave 39 on the post-35 and thence to the cradle at the vane carrying end thereof. The boom 36 is held in position as against swinging movement by .a cable 40 secured thereto and passing about a sheave 41 on a short post 42, the weight 43 being suspended from the post 35. For maintaining the vane carrier in operating position I provide acable 414C and a weight 45, shown in Fig. 5.
I claim as my invention:
1. In a water motor, a frame, a support from which said frame is suspended, a beam pivoted on said frame, a cradle carried by said beam, a vane carrier on said cradle, and means for raising and lowering said cradle.
2.

4. In awater motor, a frame, a support from which said frame is suspended, a beam adjustably' pivoted on said frame, a longitudinally disposed track on said beam, a cradle carried by said beam at one side of its pivotal connection, a weight suspended from said track and adapted to travel thereover to control the position of said beam and regulate the elevation of said cradle, and a vane carrier movable horizontally on said cradle.
5. In a water motor, a frame, a support from which said frame is suspended, a beam adjustably pivoted on said frame, a longitudinally disposed track on said beam, a cradle suspended adjacent one end of saidbeam and pivotally connected therewith, a weight movable on said track for controlling the position of said beam and regulating the elevation of said cradle, a vane carrier movable horizontally on said cradle, and a weight controlling the horizontal movements of said vane carrier.
6. 111 a water motor, a frame, a support upon which said frame is movably suspended, a' beam vertically adjustable on said frame and pivotally connected therewith, a longitudinally disposed track on said beam, a cradle suspended adjacent one end of said beam and pivotally connected therewith, a weight movable on said track, means for moving said weight to controlthe positionof said beam and regulate the elevatlon ofsaid cradle, and a vane carrier movable horizontally on said cradle and a weight controlling the horizontal movements of said vane carrier.
In testimony whereof I have signed this specification.
