CURRENT-MOTOR.
Specification of Letters Patent.
Patented Feb. 24, 1920.
Application filed fieptcmber 22, 1919. Serial No. 325,312
To all whom it may concern:
Be it known that I, HARRY HOLDEN, a citi zen of the United States, residing at Los Angeles, in the county of Los Angelcs and State of California, have invented new and useful Improvements in Current-Motors, of which the following is a specification.
This invention relates to a fluid current motor. It pertains especially to a motor having an endless carrier provided with impeller blades which are impelled by a flowing fluid, and While traveling in the opposite direction to the current are held out of the fluid; and are maintained broadside to the direction of flow while in the fluid, feathering in entering and leaving the same. The invention is especially adapted to be placed in a flowing stream of water, deriving energy therefrom which may be transmitted and used for industrial power purposes.
It is the primary object of this invention to provide novel, positive, and simple means for maintaining the impellers normal to the fluid current while therein and feathering the same as they enter and leave the water.
These objects will be more fully under stood, as will also other objects and corresponding accomplishments of my invention from the following detailed description of a preferred embodiment thereof. For the purpose of this description reference is had to the accompanying drawing, in which:
Figure 1 is a central longitudinal section through the motor; Fig. 2 is a section taken on the line 22 of Fig. 1, parts being in section; Fig. 3 is an enlarged detail in side elevation of the chain showing a bearing block; Fig. 4 is a plan viewof the motor; and Fig. 5 is a diagrammatic view showing various positions of the impeller blades during the course of their travel.
Referring more particularly to the draw ing, especially Figs. 1 and 2, A indicates a pontoon located in a stream of water 13. The pontoon supports a carrier comprising wheels, over which are passed chains having mounted thereon impeller blades and feathering means for the blades. The last mentioned structure is indicated generally b C.
Referring particularly to Figs. 2 and 3, the pontoon comprises two side walls 7 and 8 disposed in the direction of the flow of the stream. The approach thereto consists of flaring walls 9 and 10, which direct the water inwardly between the side walls, so that the greatest efiiciency from the current may be obtained.
Mounted upon the side walls near the forward ends thereof are bearing blocks 11 and 12 in which is journaled a shaft 14. Adjacent the rear end of the walls are blocks 15 and 16 in which is fixed a shaft 17. Fixed to shaft lei adjacent wall 8 is a sprocket wheel 18, and adjacent wall 7 a sprocket wheel 19. J ournaled on shaft 17 adjacent the walls are sprocket wheels 20 and 21. Extending from the middle of shaft 17 to the middle of shaft 14 and journaled on the latter is a guard 22. Passed over sprocket wheels 19 and 21 is a chain 23, and passed over sprocket wheels 18 and 20 is a chain 24. The chains 23 and 2i are similar and only one will be described. Re-
indicated by, 25.
The impeller blades are paddles of rectangular form as indicated by 26, with brackets mounted on opposite sides having stub shafts 27 and 28. Mounted upon the top of each paddle at the center thereof is a finger 29 adapted to engage the guard 22 at the shaft 1 1. Disposed on the lower edges at the corners thereof are brackets carrying feathering wheels 30 and 31. Adj acent the fingers 29 and mounted on the blades are weights 32 acting to counterpoise the paddle so that it will hang in horizontal position.
Mounted upon the inside of the side walls 7 and 8 are feathering ways 33 and 34: which extend parallel to the chain and below the same, so that when the feathering wheels 30 and 31 are disposed therein the blades 26 will be normal to the current flow. The ways are in the form of a channel, which at the forward end curves upwardly as indicated by 35 in Fig. 1, the channel being cut away on the lower side. At the rear end the ways are arcuate, the channel extending until its direction is normal to the current flow as indicated by 36 in Fig. 1.
Referring to Fig. 5 a diagrammatic View in section showing the operation of the paddles is shown. The paddle or blade in its different positions is indicated by letters of the alphabet from a to 2'. Starting with the paddle in position a, it travels in the direction of the upper arrow, remaining horizontal. In the position Z) the finger 29 approaches guard 22, and in position 0 engages the guard. It then begins to tilt or feather, until in the position d the lower end thereof enters below the surface of the water B. The impulse of the water against the blade moves the lower end thereof toward the curved portion 35 of the way, and as the blade travels backward in the direction of current flow it is righted to the position 6. Finally the blade reaches the position f and is impelled by the current flow to travel toward the rear, reaching the position 9. The blade then is raised in feathered position. In traveling to the position h, the feathering wheel is so guided that the blade is maintained upright and feathered in leaving the water. After the feathering wheel leaves the Way, the blade tilts into horizontal position as indicated by i, and then travels to the forward end. If the blade is overbalanced in either direction, guard 22 will prevent its moving into a vertical or upri ht position.
It is obvious that I have provided a current motor having few parts to produce friction. This increases the efficiency of the motor and insures positiveness of operation, avoiding difficulty such as the motor getting out of operation.
What I claim is:
1. A current motor comprising in combination, an endless carrier having a shaft, blades freely pivoted thereon so as to be presented broadside to the stream, said blades being counterpoised, a way to maintain said blades broadside to the stream While therein, means on said blades to engage said Way, and fingers on said blades to engage said shaft whereby to right said blades before entering said way.
2. A current motor comprising in co1nbination, an endless carrier having a shaft, blades freely pivoted thereon so as to be presented broadside to the stream, said blades bein counterpoised, a way partially parallellng the path of travel of said carrier so as to maintain said blades broadside to the stream while therein, said way having an arcuate guide at the forward end to guide said blades into said way in feathered position and having an arcuate rear end to maintain said blades in feathered position while leaving the stream, and fingers on said blades to engage said shaft whereby to right said blades before entering said Way.
3. Acurrent motor comprising in combination, pairs of sprocket wheels mounted on a shaft, chains passed over said sprocket wheels, blades freely pivoted between said chains so as to be presented broadside to a stream, said blades being counterpoised, a way below the lower side of said chain to maintain said blades broadside to the stream while therein, means on said blades to engage said way, and fingers on said blades for engaging the forward shaft whereby to right said blades before entering said way.
l. A current motor comprising in combination, a pair of shafts, a pair of sprocket Wheels on each shaft, chains passed over said sprocket wheels, blades freely pivoted between said chains so as to be presented broadside to a stream, said blades being counterpoised, a way partiallyparalleling the path of travel of said carrier so as to maintain said blades broadside to the stream while therein, said way having an arcuate guard at the forward end to guide said blades into said Way in feathered position and having an arcuate rear end to maintain said blades in feathered position while leaving the stream, and fingers on said blades to engage the forward shaft where by to right said blades before entering said way.
5. A current motor comprising in combination a pair of shafts, a pair of sprocket wheels on each shaft, chains passed over said sprocket wheels,blades freely pivoted between said chains so as to be presented broadside to the stream, said blades being counterpoised, a way partially paralleling the path of travel of said carriers so as to maintain said blades broadside to the stream while therein, said way having an arcuate guide at the forward end to guide said blades intosaid way in feathered position, and having an arcuate rear end to maintain said blades in feathered position while leaving the stream, a guard extending between said shafts on the upper side thereof, and fingers on said blades for engaging said guard whereby to right said blades before entering said way.
In witness that I claim the foregoing I have hereunto subscribed my name this 16th day of September, 1919.
