aeroplane controls are provided and can be manipulated to maneuver the aeroplane into different positions by a person or operator who is not familiar with the controls. He may have all the thrills and sensation of flying without the dangers incident thereto.

One of the objects of the present invention is to provide a novel and improved pilot training device in which the conventional form of aeroplane is suspended from an overhead structure by a cable, in which the free end of the cable is connected to the aeroplane at its center of gravity.

A further object of the invention is to provide a novel and improved construction of a pilot training device in which all the essential features of a conventional aeroplane are made use of and in which the aeroplane is suspended from an overhead structure by a cable which has its free end attached to the aeroplane at its center of gravity or balance, and in which the pivotal connection between the cable and aeroplane may be adjusted longitudinally and vertically with respect to the aerop ane so as to compensate or balance the aeroplane for the different weights of operators.

These and other objects are accomplished by providing a construct-ion and arrangement of the various parts in the manner hereinafter described and particularly pointed out in the appended claims.

Referring to the drawings, Fig. l is a side elevational view showing a rotary tower or structure to which my improved ty e of pilot training device may be connected t ereto for operation.

The invention in the present instance is directed to a novel aviator or pilot train ing device in which the rudimentary principles of flying may be quickly grasped by any novice by manipulating the controls of the aeroplane without the dangers incident to regular flying. The aeroplane in this instance is connected or suspended from an overhead stationary or rotary structure by a cable, the free or lower end of which is connected to the aeroplane at the center of gravity or balance, so that the aeroplane is free to tip about a substantially universal connection to all intents and purposes, 1 and Wlll go lnto all sorts of maneuvering positions at the direction of the operators control.

For the purpose of illustration I have shown one form of my invention in connection with an aeroplane construction which is substantially of the conventional form of aeroplane with the exception that the regular wing spread is not required because the major weight of the aeroplane is supported by the cable and does not require the lifting power of the conventional aeroplane.

The aeroplane in this instance comprises a main body or fuselage 10 which is supported on the usual landing gear generally indicated by the reference character, 11, which in turn is provided with the usual pneumatic tire wheels 12. Connected to therear end of the aeroplane and extending rearwardly and angularly with respect thereto is the usual tail skid 13. Pivoted on a. vertical axis 14 at the rear end of the fuselage 10 is the usual rudder 15. Pivoted to the fuselage and adjacent the rudder on the horizontal axes or shafts 16 are the usual stabilizers 17. Pivoted on the horizontal axes or shafts.

18 to each side of the fuselage 10 are the usual wings 18. All of these movable parts including the wings, the rudder and the stabilizers are connected up in the usual manner to the vertical control stick 19, so as to be positioned forwardly of the operators seat 20 in the cockpit of .the fuselage 10. The operating parts and connections for moving these various elements are essentially like the conventional aeroplane, and it is believed that a more detailed description of the same" is not necessary. The aeroplane in this instance is provided with the usual propeller 21 which is secured to the shaft 22, which is a main shaft of a motor 23. This -mot0r may be either electric motor or an internal combustion engine for furnishing the power for operating the propeller. This motor may be mounted on a bracket 24 secured to the forward end of the fuselage in any well known manner. The aeroplane thus far described contains the essential features of a. conventional aeroplane, but as previously pointed out, the wing spread is relatively shorter than in the conventional type of aeroplane.

The essential feature of the present invention includes a novel arrangement of connecting a cable at a point substantially at the center of gravity with respect to the aeroplane, and the provision of means for adjusting this connection longitudinally as well as vertically with respect to the aeroplane. This mechanism includes a 1011- gitudinally adjustable steel plate 25, which is rectangular in form and has its outer or longitudinal outer edges mounted between two spaced apart sets of angle members 26. The forward and rearward ends of these sets of spaced apart angle members 26 are secured on the oppo- "site sides of transverse straps 27. The upper straps 27 have their opposite ends turned upwardly at right angles with respect to the main body portion, as shown at 28, and are secured by means of rivets 29 t0 the opposite sides of the fuselage, while the lower straps have their opposite ends bent downwardly at right angles, as shown at 30, and secured to the opposite sides of the fuselage by means of rivets or bolts 31. The plate 25 is guided longitudinally between the spaced apart angle members 26 by guide angle members 32 which are secured to the plate by means of rivets 33. Secured on the oneside of the longitudinal center of the plate 25 are interiorally threaded brackets 34 which are spaced apart from each other and adapted to receive in threaded engagement therewith, a threaded shaft 35. The threaded shaft 35 is journalled at its forward and rearward ends in vertically extending plates 36 secured to the forward and rearward transverse straps 27. The threaded shaft 35 is retained in its bearings on the plates 36 by front and rear collars 37, which in turn, are secured to the shaft by means of pins 38. The rearward end of the shaft 35 is provided with a crank handle 39 positioned within easy reach of the operators seat 20 for longitudinally adjusting the plate 25 with respect to the fuselage. Formed integrally with the plate 25 in the longitudinal and transverse center of the bottom thereof is a boss 40 having a vertical extending threaded aperture therein. Mounted in the threaded aperture of the boss 40 is a threaded shaft or pin 41. Mounted in threaded engagement with the. bolt r pin 41 is a lock nut 42 for locking the pin 0- curely in various positions of adjustment. Secured to the lower end of the pin 41 is a collar 43. Swivelly connected to the upper end of the pin 41 through the medium of a tapered roller bearing 44 is an eye member generally indicated by the reference character 45 which has a downwardly extending housing portion 46 for engaging and supporting the tapered bearing therein. Secured to the upper end of the pin 41 by means of a nut 47 mounted in threaded engagement to reduce the threaded portion of the pin, is a circular plate 48 which has its under side bearing against the race of the roller bearing 44' Connected to the eye 45 by means of a hook 49 is a flexible cable 50. The hook 49 is prevented from disengagement with the eye 45 by means of a locking link 51 secured on the hook by means of a nut 52 mounted in threaded engagement with the thread end of the hook. The cable 50 extends from the hook 49 through a circular opening 53 located in the forward and upper portion of the fuselage 10, as clearly shown in Figs. 2 and 3 of the drawings. The upper end of this cable may be connected to a stationary overhead structure or preferably to the outer or free end 54 of the revolving structure generally indicated by the reference character 55, which may comprise two outwardly projecting beams 56 and 57. This beam 54 may be journalled on a shaft 58 which in turn is secured to a vertically extending tapered standard 59 which may be formed by converging angle members and transverse brace members of any suitable construction.

While in the above drawings I have shown my improved pilot training device in connection with a revolving tower in which two or more aeroplanes may be attached to the outer ends, it will of course, be understood that a single plane may be suspended from an overhead structure in which two vertical standards support the outer end of the overhead beam structure. In this particular case the upper end of the cable would be fastened so as to remain substantially stationary and permit the aeroplane to travel around a path defined by the cable, With the upper end of the cable forming a stationary pivot or center of the revolving aeroplane.

The operation of my improved pilot training device is as follows: let us assume that an operator is seated in the cockpit of each of the aeroplanes shown in Fig. 1 of the drawings, and that the engines or electric motors, as shown at 23 are started thereby revolving the propellers 21. The actuation of the propellers revolves the beam 55 on its axis 58 and by the manipulation of the control stick 19 the various elements, including the wings, the rudder and stabilizers may be controlled for either causing the aeroplanet of travel 'in a horizontal circular path or to bank to the right or left or to turn the nose downwardly or upwardly in accordance with the desires of the operator. It will be noted that by the single cable 50 connected approximately to a point at the center of gravity of the aeroplane that unless the controls are properly manipulated the aerolane will tip or tilt in any direction about its pivotal connection with the hook 49 of the cable. In other words, a novice in the cockpit of one of these aeroplanes will have all the thrill and sensation of manipulating and controlling an aeroplane, without the dangers incident to regular flying, and as a result of suclr will develop very quickly, the knack and experience of manipulating the controls of a conventional aeroplane, which he could not readily acquire except through long and tedious instruction with the active and actual flight .assistance of an experienced and proficient instructor. It is further pointed out that should the weight of the operator be such that it offsets the balance of the connection 50 with the aeroplane, the crank handle39 may be operated to shift the cable 50 forwardl or rearwardly to compensate or balance t e weight for any variation in the weight of the operator. This arrangement insures a connection of the cable with the center of gravity of the aeroplane regardless of the weight of the operator in the operators seat 20 in the fuselage. It will also be noted that a vertical adjustment of the threaded shaft or pin 41 may be made by turning this pin in the boss 40 of the plate 25 so as to adjust the vertical pivotal connection 49 with the swivel bracket 45.

While in the above description and drawings I ha ve disclosed an electric motor as propelling means for this aeroplane, it will of course, be understood that any other suitable means such as an internal combustion engine may be utilized and also controlled by the operator in the aeroplane, in a manmy invention to make use of the same in that connection.
