Specification of Letters Patent.

Patented Oct. 20, 1914.

Application filed May 9, 1913. Serial No. 766,632.

Be it known that I, JOHN E. MoWon'rnR, a citizen of the United States, residing at 4531 Garfield avenue, in the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Flying-.Machines, of which the following is a specification.

-This invention relates to flying-machines.

One object of this invention is to provide a flying-machine having propelling and sustaining devices or wings of comparatively large, area of blade surface and so constructed and operated that a machine of practical size may ascend vertically from the ground.

Another object of this invention is to provide a flying-machine which will maintain its lateral and also its longitudinal equilibrium automatically under all ordinary variations and changes in the velocity of the wind.

Another object is to provide a flyingmachine the automatic stabilizing action of which may at any time be supplemented or controlled by the operator.

Another object is to provide a flyingmachine Whose lateral motion may be con-' trolled by the operator even'when the machine is hovering.

' Another object of this invention is to'pro-' vide a flying-machine in which the direction of lift of the propelling and sustaining devices may be automatically or manually controlled.

Another object is to pro-vide a flyingmachin'e which will automatically maintain the direction of lift of its propelling and sustaining devices in an approximately vertical direction however far the machine may tilt over in a lateral direction.

Another object is to provide a flyingmachine which will automatically maintain .the center of lift of its propelling and sustaining devices at the highest practical point above the center of weight so that the vertical stability of the machine may be easily maintained.

Another object is to provide a flyingmachine having propeller planes or blades which are so designed, arranged and operated that a machine of practical size may be equipped with a relatively great area of propeller blade surface thereby greatly increasing the propeller thrust per applied horsepower above that obtained bythe ordinary screw form of propeller under usual working conditions.

Another object of this invention is to provide a flying-machine which will automatically maintain its forward tilt for forward flight.

Another object is to provide a flyingmachine the longitudinal inclination of which is also under control of the operator, who thereby controls the s eed of flight.

Other ob ects and desirable features of my invention will be hereinafter pointed out.

Fig. XIII. is a plan view and Fig. XIV. a side elevational view of the longitudinal stabilizing device and the driving means of the rotative rudders.

Briefly described my improved flying machine consists of a body or framework of any preferred design arranged to carry the operator, the motor and the devices for controlling and guiding. the machine, one or more pairs of combined propelling and sustaining devices each of which comprises a pluralit of planes or propeller blades which are so disposed that the combined resistances which the air offers to the rotary movement of same is in one general direction, means for causing said blades to feather or turn from a horizontal position when moving downward to a vertical position when moving upward in their rotation around the central axle of each device,- automatic means for adjusting and controlling said feathering means so that that general direction of lift will be maintained approximately vertical however for the machine may tilt over in a lateral direction, one or more pairs of rudder propellers which are smaller but of the same essential construction as the propelling and sustaining devices, automatic means for controlling the speed and direction of rotation of said rudder propellers so that. the rear end of the machine will be deprovided with only one .pair of propelling and sustaining devices, one pair of rotatable rudder devices, a pair of'horizontal plane rudders and a vertical plane rudder, it being understood that so far as my invention is concerned it is immaterial how many pairs of propelling devices are used as propelling and sustaining means or as rotatable rudder means.

Referring to the drawings which illustrate the prefered form of my invention A designates the body or supporting frame of the machine which carries the o erator and the .motor, B designates a pair 0 combined propelling and sustaining devices arranged above the frame A, and on opposite sides of same as shown in 'Fig. I. B designates the rightpropeller and B the left propeller.

The frame A may be constructed in various ways but I prefer to build it from light weight bars or rods 1 and stay wires 2 which are so combined and arranged that a light weight trussed skeleton structure is produced which has sufficient strength to carry the operator, the motor and the various other elements used in the construction of the-machine.

.751 he body A' of the machine herein shown substantially box shaped and is provided at its front end with forwardly projecting members 3 which converge at a common point and thus form a pyramidal shaped extension on the front of body A.

The propelling and sustaining device B is supported or connected to the body A by suitable braces 4 and 5 and truss-wires 6 and each of the propelling and supporting devices B and B comprises a horizontally disposed shaft 18, and a box shaped frame provided with radially projecting blade supports 9 in which the propeller blades are pivotally mounted. Each of the propellers of the machine herein shown has four blades W, X, Y and Z, whose longitudinal axes extend parallel to the center shaft 18. The X shaped blade supports 9 extend from the propeller hubs 10 and 11 to outer rims 12 and 13 which with their wire spokes 14 form a head at each end of the propeller. The two heads are connected by a box. shaped 'axle constructed of bars or rods 16 and trusswires 17 arranged a suflicient distance from the centerof rotation to safely withstand a torsional strain which if carried by a solid central axle would be very great. The ends of the central shafts 18 are journaled in suitable bearings 15 attached to braces 5.

Each of the planes or blades W, X, Y and Z preferably consists of a rigid rectangular shaped frame which comprises a central axle 19 and a plurality of rods or bars 19 on each side of said central axle and parallel thereto, and cross bars 20 attached to members 19 and 19 as shown, in Figs. V and VI,

wherein it will be seen that a set of trusswires 23 are provided for each side of the plane to resist and carry the strain to which the blade is subjected when either face is moving against the air. Each blade presents one face against the air during one revolution of the propeller and the other face during the next, etc. The plane material or fabric 21 is attached to the blade axle and to the rods or bars parallel thereto. A central strut 22 projects from either face of the blade to which the truss-Wires 23 lead from the corners, sides, ends and other. suitable points of the blade frame.

The propelling and sustalning devices 13 and B are rotated in opposite directions,

preferably over outwardly from the body A are provided with sprocket teeth on the outer rims. The chain 25. is crossed so that propeller B will revolve in the. opposite direction from B.

of energy. When the lifting forces of each could be applied to both heads of the prois making one revolution.

- faces of sprocket wheels 26 and 27. Said small circle L in Fig. XII.

A differential is combined with the I sprocket wheels 26 and 27 as shown in Fig. IV of the drawings. Said caring consists of a member 28 securely astened to the shaft of the motor 8 and provided with a plurality of rotatably mounted beveled gears 29 that mesh with beveled gears on the inner sprocket wheels are loosely mounted on the shaft of the motor so that the member which carries the pinions 29 transmits rotary movement from the motor shaft tothe sprocket wheels 26 and 27. Such a construction gives an equal pull to the two sprocket chains 24 and 25 and drives the propellers B and B at the same speed of rotation when the respective air resistances which they meet are equal and also drives the propeller on one side at a sufliciently greater speed thanthe propeller on the other side to cause said air resistances to be equal when variations in air currents would tend to make the lift of the two devices unequal. When brakes are used in connection with a differential gearing to vary thejrespective rotative speeds of the two devices it results in a great waste of the two devices are equal the center of lift will be maintained at a point midway be-- tween the two propellers as shown by the It will of course be understood that power pellers and that more than one motor may be used.

The means which I prefer to use for causing the planes or propeller blades to feather or turn from a vertical to a horizontal position and back again to a vertical position during each cycle of operations of the device B consists of driving members such, for example,1as sprocket chains 30 which pass over sprocket wheels 31 rigidly attached to the rear end of the propeller blades and also over sprocket wheels 32 which are rigidly attaehed to the propeller shaft 18. T The sprocket wheels 32 on each propeller shaft- ,may be combined into one with four rows of sprocket teeth on its outer rim as shown in. Fig. XI. I A separate driving member or chain is provided for each propeller blade.

The shaft 18 and the sprocket wheels thereon remain normally at rest while the propeller is rotating. The sprocket wheels 31 are twice [as large and have twice as many teeth as sprocket wheels 32 thereforethe blades X, Y and Z will make one half revolution while the propeller, as a whole,

The operation of this formof pro eller is fully described in my. former a p ication for patent on flyin machines, erial No.- 592,541, filed Novem er 15, 1910, and also in my application for patent on aeroplanes,

Serial No. 635,440, filed June 26, 1911. It

degree, and if the shafts 18 of the devices B and B are uniformly rotated the combined direction of lift is rotated in the same direction and to the same degree as illustrated in the diagrammatic Fig. XII wherein the dotted lines show blade positions W,

X, Y and 'Z when the machine is tilted over to the right-the feathering means remaining st-ationaryand the heavy full lines show the same relative blade positions when the feathering means is rotated with respect to the machine, to the same degree in a counter clockwise direction so that the direction I of lift of the device B, remains vertical however far the machine may turn over in a lateral direction as indicated by the arrow L K. The arrow L H indicates the direction of lift of device B when the feathering means remain stationary.

In the diagrammatic Fig. XII the small circle L indicates approximately the center of'lift and thefsmall circle G the center of weight of the machine. The 1111 of gravity is always in a vertical line ownward and if the direction of lift be vertically upward at the point L the machine as a whole will tend to rotate in a lateral direction until the center of gravity is brought to a point'immediately below the center of lift.

In order to 'Inaintain the direction of lift of the device B always approximately ver} tical, I have provided an automatic stabiliz ing device E which is placed in the body of the machine in such a position that the pendulum controlling means with which it is provided swings in a lateral direction. I prefer to construct said device as shown in Figs. IX and X of the drawings. Said de;

vice comprisesa rotative member as for example, drum 33 which is mounted on ahorizontally disposed shaft 34, one end of which rests in the hub of the stationary gear wheel 35 and the other in a suitable bearing attached tothe body of themachine. shaft 34 is also loosely mounted a motor driven member which comprises the belt wheel 36 and two. beveled friction drive wheels 37 and 38, all three of which have one common hub 39. Said hub has a groove around its middle portion into which projects the point of the bell cranlrxlever- 40'. Said lever is pivoted at its angle point to a lug projecting. from the drum The other end of said lever is attached to thependulum 41 by means of the link 42. The

s'upporting device 'B pendulum 41 is hung from shaft 41 attached to the drum 33 so that, for example, when the machine tilts over to the right the pendulum swings to the right and through the action of connecting members 42 and 40 the beveled wheel 37 is forced against the beveled friction wheel 43.

g It will be understood that Wheels 36, 37 and 38 are in continuous high-speed rotation in the direction indicated by the arrow near belt 44 which runs over wheel 36 and over belt-wheel 45 on shaft 46, said shaft 46 being rotated by the motor M by means of the belt 47 running 'over belt wheels 47 on shaft 46, and 48 on the shaft of the motor, so that when wheel 37 is brought into contactnvithmvheel 43 which is rigidly attached to the same shaft 43 as the worm 49, said right threaded worm 49 as shown in Fig. 10 will therefore rotate, over to the left, gear wheel 50 which is rigidly attached to the same shaft 51 as gear wheel 51; and as said worm and gear 49-and 50. are suitably journaled by their shafts to a frame attached to the drum 33 and as the gear wheel 51 meshes with the stationary gear wheel 35 the drum is thereby rotated over to the left until the pendulum attachedthereto is permitted to swing vertically in its normal position as shown in Fig. X. The beveled wheel 37 is thereby withdrawn from contact with wheel 43 and the rotation of drum 33 ceases and it is held in position by said worm and gear. When the machine tilts over to the left the beveled wheel 38 is likewise brought into contact with wheel 43 which in like manner rotates said drum 33 over to the right.- l have also provided an air-check 52 to prevent the pendulum from .making regular periodic and undue oscillations. The wheels or drums 53 which are rigidly attached to the propeller shafts 18 are connected to the wheel or drum 33 bymeans of wire cables or sprocket chains 55. Said Wheels 53 have the same diameter as'the wheel 33 so that their rotation will be uniform and equal, that is the uppermost point on each of these three wheels or drums is automatically maintained in its uppermost position and the lift of device B is thereby maintained approximatelyvertical even if the machine should turn completely cverin a lateral direction.

In order to enable the-operator to control the direction of lift ofI tlllie propelling and ave annular rim 57 which is-rotata 1y mounted onthe side of the drum 33 by loosely mounted guide-wheels 58. Said rim is rotated in one direction or the other by the steering wheel 65 of the combined steering device shown in Fig. .VII. Said wheel 65 is attached to shaft 66 which is connected to shaft 67 by the universal gimbal joint 68 Attached to shaft 67 is sprocket wheel 64.

provided an The members which connect sprocket wheel 64 to the annular rim 57 are the sprocket chain 63, sprocket wheel 62 on shaft 61, sprocket wheel 60 also attached to shaft 61, and sprocket chain 59 as shown in Fig. I

and Fig. X. Said annular rim 57 is held in its normal rotative position by the spring 69, one end of which is rigidly attached to the hub of drum 33 and the other end suitabl attached to the annular rim 57. Twolatera projections are attached to said annular rim, one on each side at a suitable distance from the pendulum, so that theoperator may by turning the steering-wheel 65 force the pendulum in one direction or the other and cause said drum 33 to rotate the feathering means in whatever direction and to whatever degree he may desire. When the annular rim 57 is permitted to return to its normal position the automatic action of the stabilizing device E is immediately restored.

'This device E is therefore both a steering and stabilizing means. As a steering means it gives the operator control over the lateral motion of the machine whether hovering or in rapid flight.

The longitudinal automatic stabilizing device F is essentially the same in construction and operation as the lateral stabilizing device Ebut its position in the body 0 the machine is at right angles to that of device E. The pendulum of device F swings in a longitudinal direction with respect to the machine. Said device F is provided to control the longitudinal e uilibrium or the longitudinal inclination o the machine by controlling the direction, and speed of rotation of the rotative rudder device C constituted by the small rudder propellers C and C which rotate also in opposlte directions with respect to each other, that is over-toward the body'A of the machine or over from the body A as determined by the action of the stabilizing device F.

The rotatable members C and C rotate on shafts parallel to the longitudinal axis ofthe body A and are attached above and on each side of the rear end of said body;

In construction and operation they are essentially the same as the propelling and sustaining device B. C and C are rotated by some suitable driving means as rope belts 71 and 72 which run in grooved rims 12", loose pulle s ,73 and grooved wheels 74 on shaft 5. haft 75 is journaled on the body A in sucha position as to bring friction driven wheel 76 in contact with disk drivin wheel 48 on the shaft of the motor. Said w eel 76 is suitably constructed to rotate shaft 75 and to. permit wheel 76 to be brought in contact with disk wheel 48 at any point along a horizontalline across the center of its face. Fig. I shows wheel 76 in contact with wheel 48 at its center, at which point wheel 76 is not rotated in either direction,

but when forced to the right it will revolve in one direction and when forced to the left of this point it will revolve in the opposite direction and the speed of rotation will de pend upon the distance of the point of contact from the center of disk wheel 48. Said point of contact is determined by the oper ation or action of the longitudinal stabilizing device F to which said wheel 76 is cdnnected by means of wire cable 78 and bar 80, or if desired by some other suitable means which will accomplish the same purpose. As shown in the drawings the wire cable is passed around drum 33 of device F and adjustably attached thereto b means of stud bolt and clamp 78. The ca le end from the under side of said drum passes over small pulley 79 and is attached to the left end of bar 80 and the cable end from the upper side of said drum passes over small pulley 81 and is attached to the right end of bar 80. To the left end of bar 80 is attached a collar 82 loosely fitted in a groove around the hub of wheel 76 so that when the machine tilts over forwardly too far the drum 33 rotates automatically over toward the rear of the machine which causes the upper end of cable 7 8 to move bar 80 over toward the left. By this means wheel 76 is forced to slide on shaft 75 to a position to the left of the center of disk wheel 48, therotation of which by means of the connecting members described rotates the rudder pro ellers O upwardly and outwardly from the dy of the machine. This action of device (1' depresses the rear end of the machine until its longitudinal normal position is restored. While the machine is being thus restored to its normal position the drum 33 automatically rotates to its normal position, with respect to the machine, causing the propellers of device O to gradually decrease their s eed of rotation and come to a stop when t e longitudinal equilibrium of themachine is restored. It is understood that the center of lift of the propelling and sustaining device B is vertically above the center of weight of the machine. And when the machine tilts backwardly too far the device F in like manner causes the propellers of device C to rotate over inwardly and downwardly. This action continues with greater or less s eed until the rear end of the machine is li ed so that its normal longitudinal inclination is restored. The degree of said forward tilt for forward flight may be determined by suitably adjusting the respective lengths of the upper and lower ends of cable 78.

In forward flight, the forward motion of the machine is maintained by the propolling device B which, when the machine is tilted at a forward angle, will. give an upward and forward driving impulse. The

machine will therefore glide forwardlythrough the air at a rate of speed which is ordinary p motion of the machine;

It will be understood that the feathering m'eans of device C is so adjusted that the propeller blades of C and C are brought to their respective maximum working positions, or positions, at suitable points between the two so that their rotation will give the effect indicated above.

In device F as shown in Fig. I the wheel 45 is rotated by means of beveled gears and lateral shaft 83 so that both devices E and F are driven from the same shaft 46 rotated by the motor as indicated above.

For the purpose of enabling the operator to control the longitudinal. inclination of the machine by means of the device F and the rotatable provided the iorlzontally disposed shaft 87 which is journaled to the body A and upon. which are mounted pedals 85, and the sprocket wheel 60 of device F. The annular rim 57 of device F is rotated in one direction or the other by means of said pedals 85 thereby giving the operator control of the saeed of iir ght and of the longitudinal inclination and the longitudinal equilibrium of the machine.

By means of the pedals 85 and the annular rim 57 of device F the operatormay swing the pendulum of said device toward the rear or toward the front end of the machine and thereb through the operation of device F an the rotatable rudders C, give the machine a Y desired degree of forward inclination or tilt, that is, the front end of the machine may be tilted down- 1'0 ellers C and C I have wardly for forward flight and upwardly to retard forward flight as for example to make a landing.

In addition to the above steering means I have provided the ordinary vertical and horizontal plane rudders 88, 89, and 90 which are of similar construction to the blades of the propellers. These ordinary plane rudders are of no service when the machine is hovering and may be dispensed with by suitably mounting the rotatable rudder device 0' so that it may be swung, substantially in the manner, laterally and vertically by the steerin device. As the rudder blades Wand .Y of device C are always at right angles to each other in the relative position of their planes, as are also X and Z of each rudder propeller whatever may be their 's eed or direction of rotation, said rotatab e rudder device will thus erform every function of the 'ane rudders and more as indicated above.

Within the body A I have provided a combined steering device Swh1ch enables the operator to control the machine by a comparatively small number ofsimple, easily acquired automatic muscular movements. It is a combination of means by which the operator controls the vertical and horizontal plane rudders, the direction of lift'of the propelling and sustaining device and the speed of the motor.

The steering device S comprises the hollow shaft 91 which is connected to the frame of body A by means of the universal joint 92. Attached to shaft 91 are four arms 93, 9 1, 95 and 96 to which are attached the wire ropes 97, 98, 99 and 100 which control the position of the vertical and horizontal plane rudders. Within the hollow shaft 91 is the hollow shaft 66 to which is attached the steering wheel 65, described above, by which the operator controls the direction of lift of the propellin and sustaining device B. Within the ho low shaft 66 is the shaft 101 to which is attached the wheel 102 by which the operator controls the motor M. As shown in Figs. VII and VIII of these drawings shaft 101 is connected to shaft 104 by means of the universal joint 103'. Upon shaft 104 is rigidly mounted drum 105 from which run wire ropes 106 to the throttle controlling device of the motor M. It will be noted that the three universal joints 68, 92 and 103 have one common center of motion so that the operation of one does not in any way affect the operation or osition of the others.

The horizonta rudders are operated by lifting or depressing the steering-wheel 65.

Wire ropes 97 attached to the arm 93 run over pulleys 107 and to the upper ends of the arms 108 of the horizontal rudders, and wire ropes 98 attached to arm 9 1 run over pulley 109 and to the lower ends of the arms 108 of the horizontal rudders. The vertical rudder is operated by swinging the steering device in a horizontal direction. The wire rope 99 attached to arm 95 runs over pulley 110 and to the left end of arm 111 of the vertical rudder, and wire rope 100 attached to arm 96 runs over pulley 112 and to the right end of vertical rudder arm 111.

The machine is supported when onthe ground by three wheels, two of which 113 and 114: are mounted on arms extending laterally from the front end of body A,

. and the third wheel 115 is suitably attached under the rear end of the machine. I

I am now aware that rotative propellers having feathering blades are not new but What I claim as new and desire to secure by Letters Patent is 1 In a flying machine the combination with combined propelling and sustaining devices arranged above the center of weight of the machine and rotatable on axles which extend approximatelyparallel to the direction of flight, and rotatable motor driven rudder means; of automatic means adapted to maintain, approximately vertical, the direction of lift of said propelling and sustaining means and thereby maintain the lateral equilibrium of the machine, and automatic means adapted to control the speed and direction of rotation of said rudder means and thereby maintain the longitudinal inclination or longitudinal equilibrium of the machine. 9
