FLYING-MACHINE.

Specification of Letters Patent.

Patented Apr. I3, iWIfi.

Application filed September 3. 1910. Serial No. 580,398.

To all whom it may concern:

Be it known that I, CHARLES C. WORTH- INGTON, a citizen of the United States, residing at Shawnee, in the county of Monroe and State of Pennsylvania, have invented certain new and useful Improvements in Flying-Machines, of which the following is a specification. I

My invention relates to aerial navigation, and one of its objects is the provision of an improved flying machine which will maintain its equilibrium during flight and descent, whether being propelled or not and irrespective of sudden or oblique gusts of winds or eddy currents of air.

Another object of the invention is to provide a flying machine which will be able to glide safely on its descent to the earth, or if the engine stops while the flying machine is moving slowly to descend safely by gliding or by a parachute action and without destroying the equilibrium of the machine.

Other objects of the invention will appear in the subjoined description, and the novel combinations will be particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 represents somewhat diagrammatically an illustration of my invention, the flying machine being shown in elevation, and showing also the engine, its connections and operating mechanism. Fig. 2 is a front view of the machine shown in Fig. 1. Fig. 3 is a plan view of the machine. Fig. 4 is a detail view in side elevation and partly in section of part of the mechanism for operating the direction rudders. Fig. 5 is a detail view in front elevation for the mechanism shown in Fig. 4.

Monoplane and biplane flying machines tend to be deflected from their horizontal or lateral positions by currents of air, thereby losing their stability or power to resist a tendency to fall or plunge down. To counteract this tendency movable planes manipulated by the operator and located at the extremities of the wings have been employed but these movable planes require in their manipulation great skill and experience and are often insufiicient to prevent disaster. In a multiplane constructed according to the invention embodied in the present application any tendency to be so deflected from a horizontal or lateral position is prevented by the fixed arrangement of the planes themselves which require no move able devices and no manipulation on the part of the operator who consequently may give his entire attention to the control of the engine and to the operation of the direction and elevating rudders. The floatin or buoyant feature tending to'keep the ying machine in proper equilibrium at all times is thus inherent in the aeroplane structure itself and automatic in its operation. This result is secured by the arrangement on a longitudinal axis of radially disposed planes upon which the pressure of lateral currents are about equally divided between the upper and lower sides of the central axis, so that while these currents may tend to deflect the machine from its course or to make it drift they will not disturb its equilibrium. Or should lateral currents tend to lift the supporting wings on one side of the machine and thus throw it out of equilibrium the fixed vertical plane resists this action and prevents any tendency for the machine to fall sidewise or to be deprived, by the increasing angularity of the wings, of Suficient supporting area. It will be seen that no matter how much the machine may be turned on its axis by disturbing gusts or currents of air there will always be exposed a practical unvarying surface to resist a downward or a sidewise slant-oi fall. Of course the number of these radially disposed planes may be varied to suit the .conditions or size of the flying machine. There may be three or four or more than four. The present invention relates to a particular arrangement of these radial wings or planes with reference tothe central axis and with relation to each other.

In the drawings there is illustrated a long central shaft S, extending from one end to the otherof the flying machine, and suitably supported in a like strong frame designated by the letter B; which latter in turn has suspended, from it in the usual manner skids or wheels, the latter being shown in the drawings, and serving to support the machine along the ground when it is getting ts initial impetus before rising into the air, and these skids or wheels need not be further described for they are of well known construction and have been commonly used.

Secured to this central shaft and extending vertically from both sides of it are the wings or planes A, which consist of strips of cloth or other suitable material, stretched and suitably fastened to the frame. Likewise secured to the frame and extending laterally on both sides of the central axis are two or more series of wings or planes, arranged as shown in Figs. 1 and 2 of the drawings. The preferable arrangement is indicated in -Fig. 1, in whic are illustrated two series of lateral plane the one series designated by the letters D, D, and D and the other series by the letters E, E and E It will be observed that the three members of the first series of these lateral wings D, D and D are so disposed that one follows the other in ascending steps and that the members in the second series E, E and E are likewise disposed in steps occupying practically corresponding positions with reference to the axis as the members of the first set. All of the several members of the two series are curved downward from their front to their rear edges in the manner known to those in the art as best to attain proper lifting effect.

he first and last members of each series extend in different directions one from the other, the first being directed downward from the point of connection to the frame B and the other upward, that is to say, D and E are extended downward while D and E are extended upward, the center wings or members D and E being extended horizontally or at right anglesto the central vertical planes. The distance apart. that these supporting planes are placed and their angles with reference to the frame B and their relative position, aswell as their length and width may, of course, bachanged by those skilled in the art without departing from this invention, although I have found that the arrangement shown in the drawings is a convenient and satisfactory one: By this relative location of the planes or wings greater efliciency is secured than if all the wings were disposed on the same plane. Not only do-the lateral planes and vertical plane tend to hold the multi lane in equilibrium, no matter at what spee it may be driven or what the direction of the air currents may be, but the disposition of the wings or supportin members at different levels, is of marked advantage. With a given width the sum of the areasof the several sections give a surface ehuivalent in their aggregate lengths to that of the long continuous plane or wingtsuch as isaused on the well' k nown monoplanes or biplanes, but with the distinction that the extreme length of the continuous plane tends to lateral instability and difiiculty in construction and manipulation, which disadvantages are greatly reduced by employing the subdivided planes of this invention. a

In the construction shown the width of each'wing can be reduced to that which is known to those skilled in the art to be eflicient and by placing the sections as shown in steps each supporting section will meet in its flight an undeflected current of 'air. These sections being arranged at different levels one above the other the current passing under eachof these sectional planes is prevented by this difference in levels from impinging on the next succeeding section. The fourth plane, or in other words, the first section of the second series, is, it is true, placed in a line with the first plane or first section of the first series, but it is far enough removed fromthe first plane to be unaffected by the current from it and far enough below the level of the third plane to be unaffected by the current from it.

The vertical plane or keel marked A should be of sufficient area to counterbalance any tendency of the multiplane to rotate on its central axis under the influence of gusts of wind acting on the supporting wings, and to prevent any tendency to drift unduly sidewise through the action of momentum when in theact of turning. This area ofthe vertical plane should be about equal to the combined areas of the supporting sections or wings, the relative areas of that part of 1 the vertical plane located above the central axis and that part located below the central axis being, however, governed somewhat by the location of the center of gravity of the entire multiplane. I Depending preferably from the central axis of the multiplane are supports for a platform, on which is located the engine F and the operators seat G and the wheel and steering post H. Fuel and water tanks and coolers and other necessary devices may be located in any convenient place on the structure. The engine is connected to the propeller I, preferably located in the forward end of the multiplane, through the medium of a belt or chain or an suitable gearing and the longitudinal sha t.

A rudder for steering the multiplane in a horizontal direction 1s shown in Fig. 1, designated bythe letters R R and is capable of being'manipulated by a system of bell cranks and connecting rodsfrom the steering gear to the pivot of the rudder. These connecting rods .and bell crank levers are best illustrated in Fig.1 of the drawings, in which a rearwardly extending rod T is connected at its forward end to the steering mechanism and through a system of'bell crank levers at its rear end to a pivot U, upon which the rod turns. Lifting planes or horizontal vanes V are provided at each end of the multiplane, and

the drawing, there is shown a side view partly in section and in detail, the means employed for operating the elevating-planes V, in which the steering post W is constructed with a journal X trunnioned in a bracket secured to the platform on the main frame of the machine. Attached to and made part of the journal or trunnion X is a crank L, on which are attached the rods 0, O, which are pivoted respectively to the double elbow levers N, N, which latter are by means of connecting rods fastened to the pivots of lifting planes V. It will readily be seen that when the steering post is moved away from or toward the operator it will operate on its trunnion and cause crank L to vibrate in an upward-or downward direction. It thus communicates motions to the bell cranks and through the connecting rods gives the necessary motion to the lifting planes V. In the arrangement of the double set of cranks shown, motion is given to the planes V at each end ofthe multiplane, the motion of the planes at one end being contrary or opposite to the motion of the planes at the other end. This greatly facilitates the operation of steering in the vertical direction or of maintaining the longitudinal equilibrium of the machine. Within the lower end of the steeringpost is placed a universal joint, as shown in Figs. 4 and 5 of the drawings, connected with the rod W which passes through this steering post from the steering wheel above. By means of this universal joint, when the wheel is turned in a direction to ward the rightor left the turning action is communicated to the. crank M, shown in Figs. 4: and 5, and the latter, that is, the crank, vibrates the connecting rod T, and thus operates the bell cranks which are connected to the pivot of the rudder R, and finally inturn manipulates the rudder in the desired-direction in a manner common to such mechanism. This rudder lit can also be duplicated, one being placed at each end, their motions being contrary or opposite one to the other as in the case of the lifting planes V. The method of connectin the two so as to communicate this motion eing practically the same as that above described in reference to the lifting plane.

It will be observed by an inspection of the drawings that in the specific embodiment of my invention thecentral vertical plane is substantially continuous from one end of the machine to the other, and that the upper and lower edges of'this longitudinal vertical plane are substantially arallel. The lateral planes extend directly omthe thin vertical plane and are arranged in stepped series. The lower forward plane of each stepped series extends "downwardly from the vertical plane near the axis of the" machine. The central plane of each stepped series extends horizontally from the longitudinal axis of efi'ect on the entire machine, while at the same time increasing the stability of, the machine. Each laterally extending plane is curved, as indicated in Fig. 1, to increase the lifting eflect, the aggregate of a plurality of lifting planes being greater than 7 that of a single plane of the aggregate area. The lateral planes bisect the vertical longitudinal planes and are near the longitudinal axis, so that the lateral planes can be secured in proper position with maximum rigidity. It is therefore evident that the comparatively large longitudinal vertical plane will minimize dangerous swerving of the flying machine sidewise, and also facilitate steering of the machine in the course desired.

=ll-laving thus described the principle of operation of the invention, together with one mechanism for carrying the sameinto efl'ect, I wish it to be understood that many changes may be made in the details without departing from the spirit of the invention and these changes will readily suggest themselves to persons skilled in the art, and therefore it is unnecessary to encumber the specification with an attempted recitation of all of them.
