JAMES A. HORNE, OF DENVER, COLORADO.

PROPELLING MECHANISM.

Application filed October 3, 1916, Serial No. 123563; Renewed February 9, 1918. Serial No. 216,402.

To all whom it may concern.

Be it known that I, JAMES A. HORNE, a citizen of the United States, residing at Den ver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Propelling Mechanism, of which the following is a specification.

This invention relates to improvements in propelling mechanism and has for one of its objects to provide a device which is particularly adaptable to either water or air craft, and to water or air craft of varying forms and sizes, without requiring material changes in the bulls of water craft or in the framework and other parts of air craft.

Another object of the invention is to provide a device which maybe actuated to propel the craft to which it is attached either forwardly or backwardly, and the propelling mechanism arranged to operate to propel the craft forwardly at one side and rearwardly at the opposite side, to control the steering and the turning of the craft within a short space.

Another object of the invention is to provide a device which may be applied as a ventilator or to produce strong air currents where required. I

\Vith these and other objects in view, the

invention consists in certain novel features of construction, as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention Figure 1 is a plan view, and

Fig. 2 is a side elevation of the improved device applied to a water craft;

Fig; 10 is a'front elevation of the parts shown in Fig. 9;

Fig. 11 is a detail view of the improved device applied to the hull ofa water craft ,7

with the improved propeller mechanism shown fully submerged;

Fig. 12 is a detail view illustrating the manner of employing the improved device as a ventilator;

Fig. 13 is a plan view of a portion of one side of a boat illustrating another. modified arrangement of the driving mechanism; i Fig. 11 is a side elevation of the modified structure shown inFig. 13, with a portion of the hull of the vessel broken away.

The improved device may be applied to the hulls of water craft or the frame of air craft of various TOI'IUS. and sizes, and it is not desired to limit the invention in any manner v in this respect, but for the purpose of illustration is shown in Figs. 1,2, 3, 6, 7 and 8 applied to the hull of a yacht and in Figs. 9 and 10 to the frame of a conventional aeroplane. The hull of the yacht is represented conventionally at 10 and the propelling mechanism is shown arranged to be actuated by a suitable motor, represented conventionally at 11.

The improved propelling apparatus when 7 applied to a water craft includes hollow shafts 12 extending in opposite directions through the walls of the hull of the vessel at any suitable point and supported for rotation in standards 13. The inner portions of the tubular shafts thus extend within the hull of the vessel while the outer portions extend beyond the hull of the vessel as shown in Fig. 1. In the arrangement of the mechanism shown in Figs. 1, 2 and 3 the inner H mechanism is not shown, as it forms no part of the present invention. I

Extending from the portion of each tubular shaft externally of the hull of the boat are arms 17 each pair of arms being provided at their outer ends with a pivot shaft 18. Rigidly connected to each pivot shaft between each coacting pair of arms 17 is a bucket 19, the latter being preferably semicircular transversely and closed at the ends as shown in Figs. 4 and 5. Each bucket is provided with an opening 20 closed by a valve 21 hingedly united at 22 to the inner face of the bucket. The valve 21 thus swings inwardly and admits water from the outside but will not permit water to pass from the inside of the bucket through the opening 20. A stop 23 is attached to the bucket and extends into the path of the valve 21 to limit the movement in one direction and prevent the valve from being fully opened.

By employing the valves the resistance of the air or water at the return stroke is materially decreased, while the force of the forward stroke is not diminished.

Mounted for rotation through each of the tubular shafts is a rock shaft 2% extending at its ends beyond the ends of the tubular shafts. At the inner end, each of the rock shafts 2% is provided with an operating lever 25 preferably provided with a stop pawl 26 to engage in notches in a segment 27 as shown in Fig. 3 to limit the movement of the lever and to lock it in its adjusted position, as hereafter explained.

Connected to the outer end of each of the shafts 24 are chain pulleys 28, the pulleys being provided with chains 29 operating over chain pinions 30 on the pivot shafts 18 of the buckets. By this arrangement, it will be obvious that when the levers 25 are in one position, the buckets 19 will. be held in position to constantly face with their curved portions forwardly, and when the lever 25 is reversed in position, the shafts 2% will be correspondingly rotated and cause the buckets to be reversed in position through the coaction of the chain wheels and chains, or arrange the buckets with the curved faces rearwardly. It will be understood, that at the same time that the positions of the buckets are reversed, the motor will likewise be reversed, whereby the buckets may be operated to propel the boat astern, or forwardly as required.

In Figs. 6 and 7, a modification in the manner of reversing the buckets is shown consisting in providing the shafts 24 with a beveled gear wheel 31-and the pivot shafts:

18 with'beveled gears 32. Coacting shafts 33 are mounted for rotation by hangers 34 from the outer frame members 17 and provided with beveled pinions 35 and 36 on gaging respectively with the beveled gears 3132. The shafts 33 are arranged to 0pera-te one above the other or in vertical alinement, and consequently, the teeth of the gear 31 and pinions 36 are of the oblique order as illustrated in Fig. 6. By this arrangement, it will be obvious that when the shaft 24 is actuated by the levers 25, the motion of the gears 31 will be transmitted to the pinion shafts 1S and reverse the position of the buckets in the same manner as heretofore described.

In Fig. 8 another modified construction is shown in which the inner ends of the shafts 24: are headed as shown at 37 and mounted for rotation in suitable sockets or seats in the inner ends of the tubular shafts 12. EX- tending between the confronting ends of the tubular shafts, is a connectin section or shaft 38 having an enlargement 39 at one end which forms a stop for the enlarged end 37 of one of the shafts 2st, and provided with an enlargement 10 at the other end which serves as a stop to the enlarged end 37 of the other shaft 21. The member 38 is provided with bearings at its ends adjacent to the enlargements 39-4O to engage in the bearings of the standards 13. The member 38 is provided with a chain pulley 41 over which a chain 42 leads from the chain wheel 16 of the motor. It will be noted in the arrangement shown in Fig. 8 that the tubular shafts 12 and the member 38 are rigidly coupled together so that the rotary motion of the motor is imparted constantly to both of the tubular shafts, which are thus arranged to operate togther.

In the modification shown in Fig. 8, the chain drive illustrated in Fig. 1 is employed, but attached to the outer ends of each of the shafts 24 is a crank arm 13, from which pull cables '-l4- 45 lead, as shown. Mounted upon the hull 10 of the boat, preferably rearwardly of the motor 11 are standards LG-4L7 carrying wheel like devices 4.84.9. The cable 4 1 is arranged to be wound upon a drum on the standard 46, while the cable 45 is arranged to be wound upon a drum upon the standard 47. The standards are thus rotatable independently of each other and are independently connected through the cables with the shafts 24. The cable leads over a guide pulley 51 supported by a bracket 52 from the hull of the boat, while the cable 44: passes over a guide pulley 53 supported by a suitable bracket 54 from the hull of the boat. By this arrangement, it will be obvious that the re versal of the buckets may be accomplished by manipulating the wheel like devices 4-748. If the devices 4l748 be actuated simultaneously, the buckets at each side will be simultaneously reversed but as the wheel devices are operative independently, the buckets at one side may be reversed from those at the other.

In Figs 9 and 10 the improved device is shown applied for a flying machine in which 55 represents the framework for the wings, not shown, and 56 the car for the motor and aviator. IVhen applied to a flying machine the shaft 24: is mounted upon the frame 55 above the car 56, and carries the buckets 19 and the operating mechanism, the latter being arranged at each side of the car 56 and driven by belts 15 from the motor, the latter not shown, as it forms no part of the present invention.

lVhen thus employed the buckets 19 take the place of the ordinary screw propeller device.

The buckets in the modified structur shown in Figs. 9 and 10 are shown arranged to be actuated independently, as in the other forms of the device, one set of the buckets may be actuated and the other held stationary, or the buckets operated in opposite directions to accomplish the rapid turning of the flying machine when required, and like wise to enable the aviator to cause the ma-.

chine to travel in any required directions or to turn rapidly.

In Fig. 11 the improved device is shown applied to the hull of a vessel below the water line, the level of the water being indicated by the finely spaced lines above the propeller mechanism. When thus employed no change whatever is required in the hull of a vessel, the shafts 2 1 being located at a lower point in the hull than when employed as shown in Figs. 1 and 2.

In Fig. 12 the improved device is shown arranged as a ventilating apparatus and located within an opening in a wall, a portion of which is represented at 57. The shaft 24 is located transversely of the opening, and the buckets 19 are arranged to rotate within the opening as shown. In this modification the motor 11 is located at any convenient point and arranged to actuate the shaft 2 1 and the buckets-by a belt 15.

In Figs. 13 and 14.- another modified arr'angement of the driving mechanism is shown, which may be employed, if preferred. In this arrangement, the arms 17 are attached to and rotate with shafts 57, one only being shown, which extend through the sides of the hull 10 and operate within sleeves 58, mounted for rotation in the hull,

each provided with a suitable packingde vice 59.

Each sleeve 58 is supported by a suitable bracket 60, and mounted upon the inner end of each shaft 57 is a chain wheel 61 from which the chains 15 lead to the motor as in the form of structure shown in Figs. 13 and 8.

The chain wheels 28 are connected to rotate with the sleeves 58 and carry the chains 29, as in the form of structure shown in Figs. 1-3 and 8.

In the modified structure shown in Figs. 13 and 14, the chains 29 are located between the hull 10 and the inner sets of the arms 17.

Mounted for oscillation upon each standard 60 and spaced from the shaft 57 and sleeves 58, are stub shafts 62 carrying chain wheels 63 connected by chains 6 k to a chain wheel. 65, the latter being fast on the sleeve 59. An operating lever 66 is connected to each of the stub shafts 62, to actuate the latter. Each lever 66 is provided with a stop pawl device 67 cooperating with a toothed segment 68. The mechanism shown in Figs. 13 and 14 operates in precisely the same manner and accomplishes the same results as the mechanism shown in Figs. 1-3 and 8, and does not constitute'a departure from the principle of the invention or sacrifice any of its advantages.

Having thus described the invention, what is claimed as new is:

1. In a propelling mechanism, a supporting body, hollow shafts mounted upon said body and extending from opposite sides thereof and each having radially directed arms, buckets mounted for oscillation relatively to said arms, a rock shaft extending through each of said hollow shafts, means for rotating said hollow shafts, means 0perative by said rock shafts for maintaining said buckets with their open sides in constant vertical position, a crank arm carried by each of said rock shafts, means for independently operating said crank arms to cause the oscillation of said rock shafts to reverse the position of said buckets.

2. In a propelling mechanism, a supporting body, hollow shafts mounted upon said body and extending from opposite sides thereof and each having radially directed arms, buckets mounted for oscillation relative to said arms, a rock shaft extending througheach of said hollow shafts, means for rotating said hollow shafts, means operative by saidrock shaft for maintaining said buckets with their open sides in constant vertical position, a crank arm carried by each of said rock shafts, a pull cable connected to each of said crank. arms, and means for applying strain independently to said pull cables.

In testimony whereof I aflix my signature.
