EDGAR A. MCOLUNG, OF DAYTON, WASHINGTON.

CURRENT-MOTOR.

ocaoai.

To all whom it may concern:

Be it known that I, EDGAR A. MOCLUNG, a citizen of the United States, residing at- Dayton, in the county of Columbia and State of Washington, have invented certain new and useful Improvements in Current-Motors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in endless chain current motors.

One object of the invention is to provide a machine of this character which may be arranged to operate in an open stream or in connect-ion with a water-fall.

Another object is to provide a current n10- tor in which the blades on the upper stretch of the drive chain will be automatically opened by the pressure of the water and will be automatically closed in the same manner on the return stretch of the chain.

Still another object is to provide a motor of this character which may be constructed in a plurality of hingedly connected sections, each of which is provided with an independent current operated driving mechanism geared to a common power shaft which is formed in jointed sections and extends throughout all of the motor sections.

Vith the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings, Figure l is a top plan view of the machine; Fig. 2 is a front elevation of the same; Fig. 3 is a side elevation, with parts broken away; Fig. 4 is a central longitudinal section; Fig. 5 is a horizontal section on the line 5 5 of Fig. 3; Fig. 6 is a vertical section on the line 66 of Fig. 3; Fig. 7 is a side view of a portion of the drive chain and one of the current blades, showing the latter in open or operative position; Fig. 8 is a front view of the same; Fig. 9 is a vertical section on the line 99 of Fig. 8; Fig. 10 is a rear View of the blade as shown in Fig. 8; Fig. 11 is a detail fragmentary sectional view of a portion of one end of the blades, showing the manner in which the sections thereof are hingedly connected to the drive chain; Fig.

12 is a detail perspective view of one of the links of the drive chain; and one of the coupling members for connecting the blades to the links of the chain; Fig. 13 is a fragmentary sectional view of one of the hinge connections between two sections of the motor.

In the embodiment of the invention here shown, I provide a main supporting frame 1 comprising a series of vertically disposed outer side bars or standards 2 and intermediate bars or standards 3, said bars being connected at their upper and lower ends by upper and lower cross bars 4:. The intermediate bars 8 are preferably arranged in pairs and are connected together at their upper and lower ends by longitudinal connecting bars 5. The pairs of intermediate bars 3 are spaced apart at the center of the frame to form a space or passage in which is arranged a driving mechanism, hereinafter described. The intermediate bars or standards 3 at the opposite sides of the space or passage at the center of the machine are connected together by pairs of longitudinally disposed side plates 6 which are preferably spaced apart, as shown.

The motor when arranged for use, is preferably formed of a plurality of sections, each of which comprises a frame constructed as just described and said sections are hingedly connected together by means of pairs of hinged plates 7 secured to the adjacent ends of the side plates 6 of the adjoining sections. The plates 7 overlap and on the inner plates of one of the sections is formed annular bosses 8 which are engaged by annular flanges 9 formed on the inner plate of the opposite section and said plates when thus engaged are provided with a pivot bolt whereby they are pivotally or hingedly secured together.

In one end of the upper side plates 6 of the sections, is revolubly mounted a drive shaft 10, while in the opposite end of said plates is revolubly mounted a chain adjusting and supporting shaft 11. On the opposite ends of the shafts l0 and 11 are fixedly mounted sprocket gears 12 with which are operatively engaged the sections of an endless drive chain 13. The upper and lower stretches of the chain sections are held in operative position between the gears 12 by a series of idle rollers 15 which are revolubly mounted on stub shafts secured to the inner sides of the upper and lower side plates 6. On the chain 13 is secured series of current engaging blades 16, each of which is formed of folding sections, said sections being hingedly connected at their inner edges to a supporting shaft 17 which is arranged between and secured to specially formed links 17 constructed as shown in Fig. 12 and arranged in the opposite sections of the drive chain between which the sections of the blades are adapted to open and close. One of the sections of the blades is formed at its inner edge with an extension 18 which is adapted to overlap the adjacent edge of the opposite section, when said sections are in open or extended position. Slidably engaged with the rear side of the sections of the blades are brace bars 19, the opposite ends of which are pivotally secured to studs 20 arranged in the links of the chain, whereby when said blades are in an open or extended position, the brace bars will hold and brace the same against the pressure of the water on the opposite side of the blades. On the forward or front side of one of the blades is formed a stop 21 which is adapted to be engaged by the opposite sections of the blades when the sections are brought together in folded or closed position. On one section of the blades is pivotally mounted a latch 22 which is provided with an angularly formed operating arm 23, the end of which is engaged with a suitable guide 2a arranged on the rear side of said section and said arm is engaged by an operating spring 25, also secured to said section of the blade. The latch is provided with a locking notch 26 and a beveled outer end, whereby when the opposite section of the blades is folded inwardly into engagement with said beveled end of the latch, the latter will be sprung outwardly to engage the notch 26 with the edge of said section thereby holding the sections of the blades in folded or inoperative position.

On the for ard end of the frame and in the path of movement of the beveled end of the latch 22 is an adjustable trip finger 26 having a beveled lower end which is adapted to be engaged by the beveled end of, the latch 22 as the blades pass the same, thereby releasing the latch and permitting the blades to be opened by the action of the current. The trip finger 26 is adjustably secured in the frame by means of a set screw or other suitable fastening. hen itis desired to throw the machine out of operation, the finger 26 is retracted and secured by its fastening device out of the path of movement of the latch 22 so that the latter will not be tripped by said finger and the blades will consequently be held in folded position so that when passing around, the force of the current will not act on the blades. On the opposite end of the frame is secured parallel depending blade closing arms 26 which are adapted to engage the blades 10 as they are brought around by the chain 13 and to fold said blades together to an inoperative position in which they are held by the latch 22. The blades when thus folded, do not, on their return stroke, offer any resistance to the force of the current and consequently do not act to operate the motor until released by the engagement of the latch 22 with the finger 26 arranged on the forward end of the frame. By arranging the blades as herein shown and described, the blades on the lower stretch of the chain will be forced open to an operative position by the pressure of the current and will thereby operate the drive chain and through the latter will utilize the power or pressure of the current to the drive shaft 10.

Journaled in suitable bearings in one side of the frame is a power shaft 27, the shaft of each section of the motor being connected together between the same by a universal joint connection, as shown. On one end of the shaft 27 is mounted a bevel gear 28 which is adapted to be engaged by a similar gear 29 on the drive shaft 10. The gear 23) is loosely mounted on the drive shaft and is operatively connected thereto by means of a suitable clutch 30, whereby the drive shaft may be thrown into and out of gear with the power shaft when desired.

Slidably mounted between the pairs of intermediate standards 3 and the outer side standards are hollow floats 31, said floats being provided with guide blocks 32 which are slidably engaged with vertically disposed guide tracks 33 secured to or arranged on the outer side standards and the adjacent intermediate standards of the frame. The guide blocks 32 are provided with threaded passages wit-h which are engaged the lower threaded ends of float adjusting rods 3% mounted. in suitable bearing brackets on the frame and provided on their upper ends with bevel operating gears .Revolubly mounted in the upper ends of the standards or supporting bars 2 and 3 are front and rear float operating shafts 36 on which are fixedly mounted a series of bevel gears 37 which are operatively engaged with the bevel gears 35, on the upper ends of the float adjusting rods 3%. The shafts 36 at the opposite ends of the machine are operatively connected together to move in unison and thereby simultaneously operate all of the float adjusting rods 3%, by a connecting shaft 38 on the opposite ends of which are mounted bevel gears 39 which engage similar gears 40 on the float operating shafts 36. Slidably keyed on the shaft 38 is a bevel gear -Ltl, said gear being shifted into operative engagement with a bevel gear 43 by a lever 42. The bevel gear 43 engaged by the gear 5L1 is arranged on the upper end of a vertically disposed power transmitting shaft 44 which is revolubly mounted in suitable bearings on the frame of the machine and has fixedly mounted on its lower end a bevel gear 45. The gear 45 engages bevel gears 46 and 47 loosely mounted on the power shaft 27. The gears 46 and 47 are adapted to be separately locked into operative engagement with the power shaft by a double reversing clutch 48 arranged 011 said shaft whereby the motion of said shaft is imparted to the power transmitting shaft to drive the power shaft in one direction or the other. The clutch 48 has connected thereto a shifting lever 49, to which is connected an operating rod extending to the upper end of the n1acl1ine,whereby said lever is actuated to shift the clutch and thereby reverse the power transmitting shaft from the top of the machine.

Pivotally mounted in the frame of the machine, below the floats 31, are current deflecting blades 50, which are adjusted by means of cables 5l connected to the forward ends of the blades and to winding drums 52 which are revolubly mounted in the frame of the machine, as shown. On one end of the drums 52 are arranged worm gears 53 which are operatively engaged by worms 54 on the lower ends of vertically disposed drum operating shafts 55 which are mounted in suitable bearings on the frame 1 and are provided on their upper ends with bevel gears 56.

Revolubly mounted in suitable bearings in the upper portion of the frame, is a second power transmitting shaft 57 which is formed in two sections each having gears 57 engaged with and driven by the gear 48 on the first power transmitting shaft 44 and 011 said shaft 57, adjacent to each end of the same, is slidably mounted a double bevel gear 58, said double gears 58 being slidably keyed to the shaft 57 and connected with said gears are shifting lever 59 whereby the gears are moved or shifted on the shaft 57 to bring one side of the gears into operative engagement with the bevel gears 56 on the upper ends of the drum operating shafts 55, whereby said shafts are driven to operate the winding drums in the desired direction.

Between the sections of the motor and adjacent to the outer sides of the hinged connections thereof are pairs of connecting bars 60, the opposite ends of which are hingedly connected to the adjacent ends of the motor sections by clips 61 or other suitable fastening devices. Between the bars are revolubly mounted cable winding drums 62 to which are connected and on which are adapted to be wound anchoring cables 63, the opposite ends of which are-secured to suitable anchors in the bottom of the stream. The drums 62 are provided on one end with worm gears 64 with which are operatively engaged worms 65 formed on drum operating shafts 66. The shafts 66 are preferably formed in jointed sections to permit the free movement of the adjoining motor sections and on the inner end of said shafts are fixedly mounted bevel gears 67 which are operatively engaged with similar gears 68 on the lower ends of vertically disposed shafts 69, on the upper ends of which are fixedly mounted bevel gears 70 which are adapted to be engaged by the adjacent face of the double bevel gears 58 on the second power transmitting shaft 57, when said gears are shifted in the proper direction by their shifting levers 59. By thus connecting the drums 62, motion is imparted there to from the power shaft through the connecting gears and shafts to operate the same in the desired direction.

In connection with my motors herein shown and described, I preferably employ a series of fastening cables and adjustable fastening mechanism such as shown and described in my application for Letters-Patent on improvement in rotary current motors filed September 21, 1909, Serial Number 518,823. In connection with the presentform of motor, I also employ the form of drift guards also shown in the above mentioned application.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.
