Specification of Letters Patent.

Application iiled March Z2, 1904. Serial No. 199,488.

To all whom, it may concer-71,:

Be it known that I, JOHN RAUsoI-inn, a citizen of the United States of America, and a resident of St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Current-Motors, of which the following is a specification.

My invention relates to improvements in current-motors, and has for its object simplicity of construction together with effectiveness 1n use.

A further object is greater efficiency coupled with a minimum amount of friction in operation.

To these ends my invention consists of thev features of construction and combination of parts hereinafter described and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation, partly in section, of my improved current-motor. Fig.A 2 is a plan view of the same. Fig. 3 is a front view, and Fig. 4 is a perspective view, of one of the paddles and links.

In the drawings let A represent a boat by which the parts of my improved current-motor are carried. This boat is formed with an opening 2 and a trough 3 below said opening, through which the paddles B are moved by the current of water. The front end of the trough is formed with a mouth O, the sides 4 and floor 5 of which iiare outwardly for the purpose of directing the current of water into the trough. The bow G of the boat and the front edge 6 of said floor are wedge-shaped. Vertical shutters 7 are adapted to slide up and down between the guides 8 on the bow for the purpose of regulating the quantity of water passing into the trough. Each shutter is provided with a rack 9. A series of guards 1() are positioned back of the shutters for the purpose of preventing any material entering the trough which would be liable to clog the motor mechanism to be hereinafter described. The shutters and guards are arranged in rows adjoining the front edges of the floor, as shown in Fig. 2, and shafts 1,1 are journaled on supports 12 back of each row of shutters. Pinions 13, which are feathered on the shafts, may be moved to mesh with any rack on the back of the shutters. By

turning the handles 14 on the shafts any shutter may be raised or lowered, as desired. A dog 15 back of each rack may be thrown into engagement therewith for the purpose of holding its corresponding shutter in adjusted position.

The motor mechanism consists as follows: Positioned on the upper edge of the wall 16, surrounding the opening 2 in the boat, is a shifting frame or support D, which is for the purpose of permitting the motor mechanism to be raised to allow any debris which might collect on the paddles to be carried by the current of water through the trough. The frame D is connected to the side wall 16 by means of the bolts 17, which pass vertically and loosely through the openings 18 in the shifting frame D. This construction is a means of safety to prevent the paddles or other parts breaking. Transverse shafts 19 and 2() are journaled in the shifting frame D and carry pairs of wheels 21 and 22. These wheels are formed with flat segmental peripheries 23, around which the chains E pass. These chains are composed of links 24, which are pivoted together at 25. The peripheries 23 engage the links and drive the chains continuously around the wheels. Each link shown in Fig. 4 is a bar 26 having a split end 27, which admits the opposite end23 of the adjoining link. The ends of the links are provided with openings 29, through which the pivots 25 pass. Each bar has a bracket 30 on its side, to which the paddle B is attached by the bolts 31 in inclined position, as shown in Fig. 1. The frames and bars on each pair of links are braced by means of the transverse rods 32. The paddles B correspond in length and width substantially with the dimension across the trough, so that the full power of the current of water passing through the trough is transmitted to the motor mechanism. Transmission mechanism F is connected with the motor mechanism for the purpose of conveying the power generated by the motor mechanism to 'a countershaft 33. This transmission mechanism consists of sprockets 34 and 35, respectively on the shaft 2O and counter-shaft 33, and a chain 36, which engages the teeth on said sprockets. The counter-shaft 33 carries a fly-wheel 37 and is journaled upon the supports 38, which are fastened by bolts 39 to the roof 40, carried by the boat. An idle sprocket 41 meshes with the links of the chain 36 and is swung from the bearing 42 on said roof by means of the arms 43 for the purpose of taking up the slack of the chain ivfheril the motor mechanism and frame D are ite IlO

Having described my invention, what I claim as new, and desire to protect by Letters Patent, is-

1. A device of the class set forth, consisting of a boat, an opening in said boat, a trough below said opening, the mouth of which has sides and a loor which flares downwardly, vertical shutters sliding in the bow of the boat to close the mouth of said trough, a rack on each shutter, a shaft adjoining said shutters, a shifting pinion feathered on said shaft and adapted to engage the racks on the shutters, means for turning said shaft, and dog mechanism back of said racks. 4

2. A device of the class set forth, consisting of a boat, an opening in said boat, a trough below said opening, a mouth at one end of said trough, means for modifying the size of said mouth, wheels in said opening, a wall surrounding said opening, a shifting frame, on said wall, on which said wheels are journaled, means for permitting said frame to rise vertically, chains passing around the peripheries of said wheels, each link of which consists of a bar having a split end admitting the opposite end of the corresponding' link, a ivot through the connecting ends of said links and a bracket on each bar, paddles attached to said brackets in inclined position and corresponding' substantially in width and length with the transverse dimensions of said trough, transverse brace-rods between said links, power-transmitting mechanism connected with said wheels, and means for taking up the slack of said mechanism when the frame on which the wheels are journaled moves upward.

3. A device of the class set forth, consistingof a boat, an opening in said boat, a
