WATER MOTOR.

Application filed August 27, 1924. Serial No. 78%,435.

This invention relates to water motors, embodying a water wheel adapted to be wholly submerged, the wheel including pivoted blades mounted in a novel manner so as to occupy a particular position to cause the wheel to rotate, and to subsequently shift their positions automatically so as to offer no resistance to the current at the opposite side of the wheel during, the operation of the latter.

The nature and advantages of the invention will be better understood when the following detailed description is read in cor.- nection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

Tn the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a top plan view.

Figure 2 is a view in elevation taken at a right angle to Figure 1.

Figure 3 is a sectional. view taken on line 33 of Figure 2.

Figure 4 is a perspective view of one of the blades of the wheel.

The motor forming the subject matter of the present invention embodies a stationary frame, the base of which is in the form of a cross as clearly shown in Figures 1 and 3, the frame being indicated generally at A. It will be noted. that the terminals of each base member is provided with a loop 11 by means of which the frame may be adequately secured at any desired location for use. The frame also includes a top portion 12 which has mounted thereon spaced bearings 18 for a driven shaft, the shaft being preferably made up of sections M having their adjacent ends connected by a joint 15 as shown. One

. end of this driven shaft is equipped with a bevel gear 16 which meshes with a similar gear 17 carried by and arranged centrally of a water wheel to be presently described. The component parts of the base of the frame are also connected together by diagonally disposed members 18.

The water wheel includes a frame of the same general outline as the stationary frame as above referred to, the frame of the wheel being indicated at 19 and mounted within the stationary frame for rotation. Pivoted between the upper and lower members of this frame 19 at each side of the wheel is a pair of blades of the character shown in liigur il, each blade being indicated at 20 and secured to a shaft 21 having reduced extremities These blades are used in pairs, and are so mounted upon the frame of the wheel, that the pivotal movement of one blade of each pair is limited by the shaft 21 of the other blade of said pair, while the movement of the last .nentioucd blade in the some direction is limited by a pin 23 mounted between the upper and lower portions of the wheel frame. This arrangement is clearly illustrated in Figure 8, and which arrange ment allows blades to assume the various positions shown in Figure 3 while the wheel is in operation. thus allowing; the wheel to be rotated by the current at one side of the wheel without the blades at the opposite side offering any resistance to the current as will be readily appreciated. In other words when the blades 20 of each pair are arranged inoperative position, they assume the positions shown at the right hand side of Figure 3, radially with respect to the center of the wheel. Consequently the current flowing; in the direction indicated by the an row in Figure 3 strikes the blades of said pair which cannot move with the current because of the fact that their pivotal movement is limited in this direction in the manner above described. Therefore the wheel is rotated by the current at one side of the wheel, and as the wheel rotates, the blades just mentioned are automatically swung from the position shown at the right hand side of Figure 3 to the positions shown at the top of Figure 3 being feathered to this position. Again, as the blades are swung to this position their movement is limited by one blade swinging against the adjacent side of the wheel frame, while the other blade strikes against the shaft 21 of the first men tioned blade. As the wheel continues to rotate the two blades assume the position shown in the left hand side of Figure 3, wherein it will be noted that the blades are arranged in spaced parallel relation, so that the blades will not offer any resistance to the current at this side of the wheel. As the wheel continues to rotate, the blades finally assume that operative position as shown at the lower part of Figure 3, and remain in this position until they about reach the position at point diametrically opposite the heel, or in other words at the top of Figure 3. Consequently as the wheel rotates, the gear 17 being meshed with the gear 16 imparts rotary motion to the driven shaft, and power may be taken from this shaft for various purposes.

Pivoted upon the base of this stationary frame is a. lever 24, which lever is normally held in the position shown in Figure 2 by means of a coil spring 25. Secured to the upper end of this lever is an operating rod -or element 26 which extends to the shore,

and through the instrumentality of which the lever 21- can bev moved to a position to obstruct and prohibit the rotation of the wheel when it is desired to stop the motor.

lVhile it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall withinthe scope of what is claimed.

What I claim is:

A water motor comprising a stationary frame, a movable frame of rectangular contour in plan mounted for rotation central of the stationary frame, and including spaced upper and lower frame members,

diagonally arranged members connecting the corners of said framemembers, vertically disposed blades arranged in pairs adjacenteach corner of the movable frame and pivoted between the upper and lower diagonal members, vertical members connecting the corners of the corresponding diagonal members and against which the outermost blade 01 each pair is adapted to contact the limited movement or the blade in one direction, the other blade of said pair contacting the pivot of the first mentioned blade, a vertically arranged pin connecting the corresponding; diagonal members behind said ade and adapted to be engaged by the adjacent blade of each pair when the blades are reversed with regard to the position first mentioned, with the outer blade then contacting the pivots of the inner blade, each pair of blades being adapted to occupy posi- 'tions to cause the frame to rotate, and subsequently fi their positions automatically-to ofi'er no resistance to the current at the opposite 01'"; the frame as described.
