ALBERT H. WYATT, OF PEARL, IDAHO.

MOTOR.

Application filed May 9, 1914.

To all whom it may concern:

Be it known that I, ALBERT H. WYATT, a citizen of the United States, residing at Pearl, in the county of Boise and State of Idaho, have invented certain new and useful Improvements in Motors, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in motors and has relation more particularly to a device of this general character wherein the power is generated by a current of Water, such as in a river or the like; and an object of the invention is to provide a device of this general character having novel and improved means whereby the device may be assembled with convenience and facility and which may be readily adjusted. into or out of operative position.

The invention also has for its object to provide a device of this general character including a hollow rotatable body provided with novel and improved means whereby any water which may enter therein will be discharged in substantially an automatic manner.

The invention consists in the details of construction and in the combination and arrangement of the several parts whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in the appended claims.

In order that my invention may be the better understood. I will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure 1 is a view in top plan of a motor constructed in accordance with an embodiment of my invention; Fig. 2 is a sectional view taken substantially on the line 22 of Fig. 1; Fig. 3 is a fragmentary side elevational view, with parts omitted, of the device as illustrated in Fig. 1; Fig. 4 is a top plan view of the structure illustrated in Fig. 3; Fig. 5 is a side elevational view, on an en larged scale, of the rear portion of the buoyant body disclosed in the preceding figures, and illustrating the operating wheel of the motor; Fig. 6 is an enlarged transverse sectional view taken through the operating wheel, as herein disclosed, with the blades and their concomitant parts shown in eleva- Specification of Letters Patent.

tion; and Fig. 7 is a fragmentary longitudinal view taken through one extremity of the operating wheel as herein embodied.

As disclosed in the accompanying drawings, 1 denotes a float of any ordinary or preferred construction adapted to be suitably anchored in a stream, such as a river or the like, and, as herein disclosed, such float includes the upstanding side walls 22 through which the opposite extremities of the driving shaft 3 project, such shaft extending transversely of the float and being adapted to have suitably coupled thereto any mechanism which is desired to be operated, and which in itself forms no particular part of my present invention.

As it is preferred that the float 1 be produced of wood or other similar buoyant material, I find it of advantage to provide on the exterior surfaces of the side walls 2 the castings 4.4 of any suitable metal and having their forward extremities provided with the outwardly disposed circular projections 5, each of such projections being provided at its axial center with an opening 6 also extending through the casting 4 and through which is adapted to project the extremities of the driving shaft 3, whereby it will be readily seen that such castings 4 serve as bearings for such shaft 3. Positioned adjacent each side of the float 1 and projecting rearwardly therefrom are the arms 7 being tied or connected intermediate their length by the cross arm 8. The inner or forward extremities of each of such arms are provided with the rounded recesses 9 adapted to snugly engage the periphery of the circular projections 5. The upper and lower edges of each of the arms 7 are provided with the perforate lugs or cars 10 through which are freely projected the extremities of the yoke 11 which has its base portion 12 rounded in order to effectively engage the circular projections 5 while the free extremities of the stems 14 of such yoke are threaded and engaged by the nuts or burs 15, whereby it will be readily perceived that a convenient and effective support is afforded for each of the arms 7 and whereby such arms are free to rock or swing, for purposes which will hereinafter be self-evident.

Suitably mounted in the outer or free extremities of the arms 7 is the tubular shaft 16 which has suitably affixed thereto, preferably by the binding or set screws 17, a hol low cylindrical body 18 of predetermined dimensions. As herein disclosed, such cylindrical body has its peripheral well produced from a plurality of longitudinal sections 19 formed preferably of wood, although any other buoyant material will suffice. These longitudinal sections form a cylindrical body which is closed at its ends by the heads 20 also preferably of wood, and such sections 19 are clamped to such heads through the medium of the annular metallic straps 21 disposed therearound and in close proximity to the opposite ends thereof. Each of such heads has suitably secured thereto a metallic spider 22 having formed at its axial center the collar 23 serving as a bearing for the body 18 and through which the binding or set screws 17, hereinbefore referred to, are disposed.

Suitably secured to each of the clamping straps 21 are the brackets 24 substantially L-shape in form, with the stems 25 thereof radially disposed, the brackets of one strap 21 being alined with the brackets of the second strap whereby the blades or paddles 26 are operatively assembled relative to the body 18.

The extremities of the tubular shaft 16 project beyond the arms 7 and to such pro jected portions are suitably fixed the sprocket wheels 27 around which are adapted to be directed the sprocket chains 28 which are also disposed around the sprocket wheels 29 suitably affixed to the projected extremities of the shaft 3, hereinbefore referred to.

As is thought to be obvious, the cylindrical body 18, after the float has been suitably anchored in a river or the like, is caused to be partly submerged within the water and, as is believed to be clearly apparent, the current of the stream will impart axial rotation to the cylindrical body 18 which will result in the requisite rotation of the driving shaft 3.

I have found in practice that water will find its way within the cylindrical body 18 and unless means are provided for permitting the discharge of such water the efliciency of the motor is materially atl'ected. As herein disclosed, I provide on the inner wall of the cylindrical body 18, the longitudinally disposed trough 30 which is adapted to receive the water within the body 18 as the same revolves, and in communication with such trough at substantially midway thereof is the flexible tubing 31 which is caused to be directed a predetermined number of times, as indicated at 32, around the tubular shaft 16 and has its opposite extremity in communication with the bore of such shaft whereby it will be readily perceived that as the body 18 rotates any water which may be collected therein is caused to be discharged through the tubular shaft 16 in substantially an automatic manner. It will also be observed that the particular manner whereby the arms 7 are pivotally engaged with the circular projections 5 affords a means whereby the tension of the chains 28 may be controlled.

l Vhile I do not wish to be limited to any particular manner whereby the float 1 may be anchored in the stream, I prefer to employ the arrangement disclosed in the accompanying drawings whereby a suitable cable 33 or the like is disposed across the stream and has slidably engaged therewith the carriage 34 including the connected arms 35, in the corresponding extremities of which are suitably supported the double sheaves 36 around which are directed, in the usual man ner, the flexible members 87, one extremity of which being anchored, as at 38, to the bow of the float 1, with an intermediate stretch 3Q directed around a single sheave 40 also suitably secured to the bow of the float 1 while the opposite extremities of the flexible members are directed around the idler pulleys 41 suitably mounted within the apertures 42 produced in the side walls 2 of the float and engaged with the vertically disposed rotatable shaft 43 provided at its upper extremity with the bull wheel 44 whereby such shaft may be rotated as desired. By this arrangement it will be readily perceived that when it is desired to direct the float out into the stream or back to the shore, it is only necessary to impart axial movement to the shaft 43 whereby such longitudinal inclination will be given to the float 1 as to cause the same, under the action of the current, to travel as directed. In order to facilitate this operation or manipulation of the float 1, I find it of advantage to have the body proper thereof mounted upon the longitudinally disposed spaced pontoons 45 having their bow portions pointed, as indicated at 46, as and for a purpose which is believed to be clearly apparent to those skilled in the art to which my present invention appertains.

From the foregoing description, it is thought to be obvious that a motor constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and by reason of the effectiveness with which it performs its functions, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice. It is also to be observed that the blades or paddles 26 are maintained in substantially rigid relation through the medium of the brace members 47 connected at their extremities to adjacent blades or paddles, as is believed to be clearly shown in the accompanying drawings.

I claim:

1. A device of the character described comprising a buoyant body including upstanding side Walls, castings secured to such upstanding Walls, a shaft operatively supported by such castings, the portion of each of the castings surrounding the shaft being provided with circular projections, a frame projecting beyond the adjacent extremity of the buoyant body and having its inner ends in engagement with the circular projections of the castings, a yoke carried by the adj acent portions of the frames and surrounding the circular projections, a rotatable member mounted in the frame, and an operative connection between the rotatable member and the shaft whereby the member and shaft are caused to rotate in unison.

2. A device of the character described comprising a buoyant body including upstanding side Walls, castings secured to such upstanding Walls, a shaft operatively supported by such castings, the portion of each A in engagement With the circular projections f of the castings, yokes adjustably connected With the frame and directed around the circular projections of the castings, a rotatable member mounted in the frame, and an operative connection between the rotatable 1" member and the shaft whereby the member and shaft are caused to rotate in unison.

In testimony whereof I hereunto aflix my signature in the presence of tWo Witnesses.

ALBERT H. WYATT.
