The present invention is directed to a device which is adapted for the use of training pilots or aviators, and familiarizing them with the various controls of the conventional type of airplane.

The device may also be adapted for the use-of an amusement device in which the operator of the same may manipulate the controls of the airplane for guiding the same Without the danger of a crash. One of the .important or primary objects ofthe present invention is to provide a device in which an airplane is permitted to move bodily with respect to the revolving struc-ture,- so that the operator thereof can guide, dip, dive, or bank the plane, and is permitted a wide rangeof control of the airplane within the limits of the range of the flexible cable connecting the plane to the revolving structure.

A still further object of the invention isv to provide a novel and improved aviator training device, amusement device, or toy, in which the conventional type of airplane is complete in every respect with the exception that the airplane is minus the propeller and the motor, and is held in captivity or con-` nected with the revolving fra-me structure with a flexible cable, which may be lengthened or shortened for varying the range lof the free movement of the airplane with respect to the revolving structure.

A still further object of the invention is tov provide a simple arrangement of an inclined braced trestle structure in the form of a beam, in which one end'thereof is pivoted to a post withthe intermediate portion thereof supported on a `truck adapted to travel on a circular track.

The description of my improved device 'will be directed to an aviators training device, but it will of course be understood that t-he same may be adapted as an amusement device or may be made in miniature form for use as a toy.

These and other objects are accomplished by providing a construction and arrangement of thearious parts in the manner hereinafter described, and particularly pointed ont in the appended claims.

Referring to the drawings,

Fig. 1 is a front elevational view of my improved aviator training device showing the cross section of the ground or support on which the device is mounted; and

Fig. 2 is an end elevational view of the 55 same.

In the drawings I have illustrated one embodiment of my invention which is an improvement over the form of my invention described and claimed in my co-pending ape0 plication Serial No. 342,959, filed Feb. 27, 1929, on Device for training aviators or for amusement purposes.

In the drawings I have shown a trestle revolving structure comprising a. single beam generally indicated by the reference character 10, which is preferably made of four sets of angle irons 11, which are secured together by steel plates 12 at the center thereof, at which point they are held in relativelyspaced relation with -respect to each other, and converged towards the other ends thereof, so as to form the effect of two tapered beams. .These angle members are suitably braced with cross braces as indicated at 13 on the four sides 75 thereof. The inner end of the beam 10 is provided with a pivot bracket 14, which is secured thereto in any well known manner. This pivot bracket is ournalled on a stud 15,

which in turn is imbedded as shown at' 16 in .80

a cement block or pillar 17. The cement block 17 is in turn imbedded in the ground in any well known manner. Extending concentrically about the cement pillar 17 is a cement base 18 having a circular recess 19 in which a 85 circular track 20 is mounted. The revolving beam 10 is supported and sustained in an ini clined position of substantially 30, as shown in Fig. 1 of the drawings by a revolving truck generally indicated bythe reference character 9 21. This revolving truck comprises a platform frame structure 22, which is mounted on conventional form of flange car wheels 23. This truck is suitably braced and supported by -supplemental frame members 24. Each 95, of these wheels is driven through the medium of electric motors 25 supported to the substructure of the truck 21, geared to each of the 'respective wheels by means yof belts 26.

Mounted on the platform 22 ofthe'truck 21 is I mi a control cabin 27 in which kthe operator may be seated for controlling the operation of the device. This truck 21 is provided withl two diverging reinforced frame members as shown at 28, which have their upper ends suitably connected to the beam in any well known manner. Each of these diverging end of the cable 32 is connected to the nose of.

the airplane ata point where the propeller would ordinarily be located. The airplane is of the regular type, and provided with the usual fuselage, wings, ailerons, rudder and tail, as well as the controls for manipulating the usual movableparts thereof so that the direction of the airplane is under the control of the operator seated in the fuselage. The airplane is also provided with a conventional form of landing gear so as to insure proper landing of the airplane on the ground when the revolving beam comes to rest. J

In the manner similarly described in my previous co-pending application, the length of the cable connecting the airplane with the revolving beam may be increased or diminished @so that the range of freedom of the plane with respect to the end of the beam ma be controlled by the loperator in the cabin 2g I ofthe truck 21.

From the above description it will be seen that when the operator in the cabin 27 connects or operates the control for driving the electric motors 25, which in turn drive the truck Wheels 23, thebeam 12 will be revolved about its pivot 15, which in turn will cause the airplane to rise from the'ground and Afollow the path described by the outer or free end of the beam 10, and when sufficient speed is attained, .the operator in the airplane may manipulate the controls for the purpose of banking, diving or doing other stunts vwithin the range of freedom permitted by the cable. These various stunts maybe indulged in by the operator without fear of a crash on account of the connection of the cable with the free end of the arm or beam of the device.

From the above description it will also be seen that I have provided a very simple device in which by providing the inclined beam I have eliminated the necessity of a large center standard structure as is required in my previous co-pending application, and as is disclosed inprior patents of this general conn struction. It will also be noted that any number of these beams from one to six may be the same may similarly constructed and connected together about a single track, so that a greater number of these devices or beams may be manipulated Ivby the one operator.

While in the above specification I have described my device as being particularly adapted to'an aviators training device, it will of course be understood that the same is capable of use as an amusement device, or be made in vminiature form with the t-ruck thereof driven by a spring motor, so that the principal features of my invention may be the embodiment of a-toy.

While in the above specification I have described one embodiment which my invention may assume, in practice it will of course be understood that the same is capable of modification, and that modification may-be employed without departing from the spirit or scope of my invention, as expressed in the following claims.

Whatk I claim as my invention and desire to secure by Letters Patent is:
