AMUSEMENT APPARATUS.

Application filed April 10, 1920.

To all whom it may concern:

Be it known that 1, JOHN Mn'rzcnn, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Amusement Apparatus, of which the following is a specification.

This invention relates to an apparatus of the type employin a series of passengercarrying devices a dapted to be swun or carried in-a circle about a support. guch passenger-carrying devices are frequently in the form of aeroplanes and the passengercarrying devices are suspended from the support by rods or cables.

In many apparatus of this type, the stationary supporting structure rises to a considerable height above the ground, thus giving opportunity for the cables connecting the passenger-carrying devices with the rotary element of the apparatus, if one of the cables should become broken, to be wound around the stationary supporting structure and thus draw the passengercarrying device, partly supported by said cable, into engagement with the stationary supporting structure, thus exposing the passengers to liability-of injury. An object of this invention is to avoid liability of injuring the passengers in this manner .if, for some reason or other, the passengercarrying device should move toward the supporting structure and engage the same.

Another object of this invention is to produce a supporting structure, for captive aeroplanes or other passengercarrying devices, in which the rigid members of the supporting structure are mounted in such manner that the entire structure can be readily rotated.

Another object is to produce a structure of relatively great strength and light weight.

' Another object is to provide for simplicity of construction of the apparatus.

Another object is to provide for ease of assembling and disassembling the apparatus.

Another object is to securely anchor the rotating support to the base soas to withstand all forces tending to overturn said support.

Another object is to so arrange and construct the various members thereof, that Specification of Letters Patent.

Serial No. 372,776.

strains due to unbalanced loading of the structure will be transmitted to the base as simple tension and compression forces.

Other objects and advantages will appear in the subjoined detailed description.

The accompanying drawings illustrate the invention.

Figure .1 is a side elevation of an apparatus embodying the invention.

Fig. 2 is a broken plan view of Fig. 1.

Fig. 3 is an enlarged side elevation of the supporting structure, and the base thereof, the View being from the line w w Fig. 2.

' Fig. 4 is a the base.

Fig. 5 is an enlarged broken plan view from line indicated by w -w Fig. 3, showing details of the rotary mounting and the driving mechanism. 1

Fig. 6 is an elevation, partly in section on line indicated by a2w Fig. 5.

There is provided a base, indicated in general by the character 1. The base may be of any suitable construction and in the drawings is illustrated as being composed of a number of structural iron members fabricated in a manner well understood in the art pertainin to the fabrication of metal structures. he base 1 is provided with bearings 2 for a horizontally positioned shaft 3 provided at its outer end with a universal connection 4 for coupling the shaft 3 to a power shaft 5 which may be driven by any mechanical power.

The inner end of theshaft 3 is provided with a bevel pinion 6 meshing with a bevel gear 7 on a vertical stud or pin 8 which is stationarily mounted in a bearing 9 of the base 1. The gear 7 connects with a spur pinion 10 engaging an internal gear 11 on the lower. end of a supporting structure indicated in general by the character 12. In this instance the gear 11 is fastened to a circular angle member 13 of the supporting structure and said structure also comprises a circular girder 14 to which the angle member 13 is attached. The supporting structure 12 also comprises a central hub 15 which is connected by radial spokes or arms 16 to the girder 14. Projecting down- Wardly from the hub .15 is a stub shaft 17 journaled in a bearing 18 of the base 1. In this particular instance the base 1 is cone plan View of Fig. 3, omitting shaped and the bearing 18 is positioned at the apex of the cone.

The supporting structure 12 is otherwise constructed as follows: The girder 1a provides a rotary mounting for thelower ends of upwardly and inwardly slanting compression members forming supporting legs 20, the upper ends of said legs being engaged by a collar 21 on a vertical stem 22. Connected at their lower ends to the stem 22 are upwardly and outwardly slanting compression members forming radial arms 23. In the particular instance shown in the drawings the arms 23 are siX in number as are also the legs 20, and each of the arms 23 is positioned directly above one of the legs 20. The upper end of each of the arms 23 is connected by a tension member in the form of a cable 24 to an ear 39 mounted on the upper plate 19 of the girder 14, said ears being positioned adjacent the lower ends of the legs 20. The connections of the cables 24 with the arms 23 are in staggered relation with the connections of' said cables with the girder 1 1, that is to say, the cables 2 1 extend aslant circumferential of the apparatus as clearly shown in Fig. 1 of the drawings. Each arm 23 is connected by two of the cables 21 with two different legs 20 on opposite sides of a vertical plane passing through the arm 23; and each of the legs 20 is connected by two of the cables 24: to alternatively positioned arms23.

The upper ends of adjacent arms 23 are connected to one another by tension members in the form of a cable 25; The lower end of the stem 22 is provided with a ring 26 to which is connected the upper ends of tension members in the form of a cable or cables 27 which are fastened at their lower ends to rings 28 mounted on the upper face of the hub 15.

Connected with each of the arms 23 is a tension member 35 and thetension memhere are all connected to one another by a suitable coupling 36 which, in this instance, is in the form of a plate that is provided with marginally positioned eyes through which the tension members 35 pass.

The bottom plate 29 of the girder 14 forms a track resting upon andsupported by a series of rollers 30 which are rotatively "mounted in pairs on radial members 31 of the base, said radial members being connected' at their inner ends with the bearing 18.

Any suitable passenger carrying devices 32 may be suspended by tension members in the form of cables 33 from the arms 23, in this particular instance said devices being shown in the drawings in the form of aeroplanes provided with planes 38 and propellers 34:. The propellers 34 may be driven by any suitable means, not shown, such means being well understood in this art and therefore requiring no description herein.

Preferably the lower ends of two adjacent cables 33 will be connected with one of the devices 32, and the upper ends of said cables may be connected with different arms 23 positioned adjacent one another.

The stub shaft 17 is provided with a nut 37 forming a shoulderto prevent said shaft from being pulled out of the bearing 18 by a tendency to tipping of the supporting structure 12 in event of the load on said structure being greater on one side than on the other side.

In practice, the entire supporting structure 12 will be rotated by driving the shaft 5, thus causing the passenger-carrying devices 32 to be swung outwardly and upwardly by centrifugal force. If the loading of the different passenger-carrying devices should be uniform, which in practice is not realized, the centrifugal pull of the tension members 35 would be uniform and there would be no tendency to upsetting of the structure 12; but a greater load in the passenger-carrying device on one sidethan in that on the opposite side produces a turning moment about the base and such turning moment is counteracted by the tension members 27, shaft 17, hearing 18 and nut36.

From the foregoing it will be clear that the apparatus is of simple and light construction relative to the loads which it is designed to support and to the unbalanced centrifugal forces to which it is subjected when in operation, the unbalanced effect, when the load is not uniform in the various passenger-carrying devices, multiplying rapidly as the speed of rotation increases.

The invention is not limited in its broader phases to the exact details of construction shown in the drawings and above described but the invention includes whatever changes may be made falling Within the spirit and scope of the appended claims.
