Patented Oct. 10, 1950 UNITED STATES PATENT OFFICE 22 Claims. My invention relates in general to amusement devices and in particular to rotary swings. The principal object of my invention has been to provide an amusement device of this nature which may be easily collapsed for ready transportation from one place to another. Another object is to provide a rotary swing which may be collapsed for transportation or storage without having to disassemble the various parts of the device. A further object is to provide a device having a rotary supporting member which may be easily disconnected from the driving mechanism, and be moved laterally and axially to permit the same to be lowered, whereby the height of the device when collapsed is reduced sufficiently to permit transportation. A further object has been to provide a collapsible supporting ring having hingedly connected parts foldable to positions adjacent the supporting standard of the device. Moreover, it has been an object to provide means for temporarily attaching the seats to the standard while transporting the device without having to disconnect any of the cables. Furthermore, my device is provided with means for holding the seat-supporting ring of the device temporarily in fixed position while passengers are being seated, means being also provided to maintain the ring in its normal operating position and to absorb abnormal shocks placed upon any part thereof. The above objects and advantages have been accomplished by the device shown in the accompanying drawings, of which: Fig. 1 is a side elevation of the complete device with portions thereof shown in collapsed position. Fig. 2 is a plan view thereof. Fig. 3 is an enlarged fragmentary side elevation taken on line III-III of Fig. 2. Fig. 4 is an enlarged fragmentary view of one of the hinged joints between the parts of the ring. Fig. 5 is an enlarged View of one of the seats of the device; and, Fig. 6 is a fragmentary enlarged View showing one of the seats temporarily attached to the standard in position for transportation. My device comprises a standard IG mounted upon the chassis of a trailer I2. Since my device is designed to be conveniently transported from place to place, the trailer I2 is provided with suitable wheels I3 and drawbar I4 at the forward end of which is a suitable connector l5 for attachment to a suitable vehicle for towing the device. When the device is erected and is in position to be used, suitable blocks I6 are placed under the chassis so as to lift the wheels I3 slightly off the supporting surface and thereby steadying the device while in use. The standard I0 is provided with upwardly extending corner members 2B which extend from the chassis II upwardly in converging manner, having their upper ends secured to a top member 2|. The corner members and the top members are preferably made of structural steel of angle iron cross section, and the top member is so disposed that the flange 22 thereof extends inwardly, thereby forming a support for the mounting flange 23. This mounting ange is secured to the flange 22 by means of a bolt 24 during the time that the device is in use, and is removed therefrom when the device is to be collapsed, as will be described hereinafter. The mounting flange 23 supports the upper antifriction bearing 25 of my device, the stationary member 26 thereof being bolted to the mounting flange 23. The rotatable member 30 of the bearing is secured to a supporting flange 3|. This flange has a hub portion 32 having a set screw 33. A rotatable tubular member 34 is supported by the upper bearing 25 and passes through the bearing, the mounting flange 23 and the supporting ange 3|, and it is secured against relative rotation with the flange 3| by means of a set screw 33. The rotatable tubular member 34 extends downwardly and a column flange 35 is permanently secured to the lower end thereof. This ange is mounted upon a drive flange 36 which is supported by the rotary member 43 of the lower anti-friction bearing 4I. The stationary member 42 of this bearing is supported by a supporting flange 43 permanently secured to the upper end of a tubular supporting column 44. The supporting nange is mounted upon oppositely arranged cross members 45 carried by braces 46 attached to the corner members 20 of the standard. The lower end of the tubular support is provided with a lower supporting collar 5I) which rests upon a chassis support 5I. Bolts 3l serve to clamp together the rotary tubular member flange 35, drive ange 35 and the iange of the rotary bearing member as one unit. A drive shaft 53 extends up through the tubular supporting column 44, having its upper end provided with splines and connected thereby to the hub 54 of the drive flange 35. The lower -end of the drive shaft is suitably connected to 3 a speed reducing device 55, mounted preferably upon the chassis support 5| and driven through suitable connecting means by the motor 5B. This motor may be an electric motor, or the source of power for the device may be derived from a gasoline Vengine or the like. The upper end of the rotary tubular member 34 extends upwardly a considerable distance above the top of the standard where it is provided with a guy wire drum 60 which is permanently fixed thereto. A seat support ring 6| is mounted near the top of the standard and is held in position by means of a plurality of pairs of guy wires 62 secured to the guy wire drum and to the ring. The ring of my device is preferably of polygonal shape. The guy Wires of each pair extend from the common point of attachment to the ring to opposite sides of the drum and are preferably wrapped about the drum so that the pull proof the ring through which a hinge bolt l is extended, whereby the point of hinging will be below the lower edge of the parts of the ring. A bolt l5 is passed through the members of the hinge near the upper ends and serves to keep the hinge in closed position. As shown in Fig. 4 one of these hinges is illustrated in closed position in full lines and in its partly opened position in dot and dash lines. I The ring 6| is preferably strengthened by a plurality of braces 'it and Tl extending across the interior of the ring and arranged in two superimposed groups of square-shaped formation, each group of braces being secured to the ring at the corners thereof. My device is provided with a plurality of seats 80 suspended from cables 8| which extend upwardly from the seat to a spacing bar 82 above which the two cables converge and are suitably attached to the ring. As shown in the drawings each pair of cables is preferably attached to the ring at points where the relatively fiat sides of the perimeter converge, and each pair of guy Wires are preferably also attached at these points so that the weight of the occupant of each seat is taken directly by the guy wires, the ring acting as a spacing medium between the seats. Each of these seats is preferably provided with a safety belt 83, secured at one end to the seat and extensible across the lap of the occupant and being attached at the opposite end by a suitable snap fastener 84 to the opposite supporting cable 3|. A back strap 85 may also be provided for each seat, the ends of which are secured to the supporting cables 8|. Mounted above the hub 32 of the supporting flange 3|, and surrounding the rotary tubular member 34 is a leveling disc 86 having a hub 90 which may be securely attached to the tubular member by means of a set screw 9| carried by it. Connecting this disc with the ring are a plurality of leveling wires 92, one extending from each corner of the square brace member formed by the braces Tl and having its inner end connected to a helical spring 93, which in turn is carried by the disc. The springs are of such strength as to 4 keep the ring 6| in normal operating position but serve to absorb any shock given the ring by suddenly applied weight at one side thereof. It is desirable in a device of this nature to maintain the ring in a substantially fixed position while passengers are being seated, and to this end I provide horizontal holding wires 94. These wires extend preferably from the corners of the brace member formed by graces 16 toward the disc where they pass under idler pulleys 35, extending therefrom upwardly to a point of union at 96 with a common vertically arranged holding wire |00. The common wire extends upwardly over an idler |0|, located near the top of the rotary tubular member 34, through the wall of such member, down through the interior thereof to a point below the upper bearing 25 where it is passed outwardly through the wall and over an idler |02 to a holding drum |03. The holding drum as well as the idlers |0| and |02 are carried by the rotary tubular member 34, and the drum is arranged at a height convenient for the operator, whereby the holding wires may be drawn taut so as to keep the ring and the seats in a substantially fixed vertical position while the device is being loaded with passengers. After loading, the holding wires are released and the device is ready to be placed in operation. When my device is to be used, the ring is, of course, in its extended position as shown by the full lines in the drawings. The seats are occupied by the passengers while the ring is held substantially in fixed position by the holding wires, as just above described. After the seats are occupied by the passengers, the holding wires are released as hereinbefore stated, and power is supplied to the drive shaft 53 by the motor 56. This rotary movement is transmitted directly 'to the rotary tubular member 34 by means of the shaft and drive flange 36, and to the seat-supporting ring by means of the drum and attached guy wires, When the device is to be collapsed for transportation or storage, the bolts 31 holding together the flanges 35, 36, and 40 are removed. The bolt 24 securing the upper bearing to the top member is also removed, and the set screws 33 and 9| carried by the support flange and leveling disc are loosened. Then by means ofv a suitable tackle (not shown) secured preferably to the top member of the standard and attached to the rotary member the entire rotary assembly is elevated sulnciently to cause the column flange 35 to clear the drive flange 3S whereupon the rotary assembly is moved laterally upon the flanges 22 of the top member.y After the assembly is moved laterally sufficiently to permit the flange 35 to clear the adjacent cross member 45, the entire assembly is allowed to slide downwardly through the upper bearing 25 and the hubs 32 and 90 of the supporting flange and leveling disc, respectively, until it occupies a position substantially like that shown by dot and dash lines in Fig. 1. Either before lowering the rotary assembly or thereafter, the bolts l5 of the ring hinges are removed and the parts 63 and 64 of the ring are allowed to move downwardly about the hinges as pivots, until they occupy substantially the positions shown in dot and dash lines of Fig. l where they will remain suspended from the hinge bolts 14. When the device is in its collapsed position, the seats are preferably attached to a seat suspending wire |04 by having the safety belt 83 looped around the wire and the snap fastener 84 at the end thereof attached to one of the seat suspending cables 8l, as clearly shown in Fig. 6. Obviously when the device has been transported to the place of use, it is only necessary to release the seats from their attachment to the wire 104 after which the ring may be hinged about .the hinge pins 13 and fastened in its extended position by means of lock bolts 15. The rotary assembly is then elevated by the hoisting mechanism (not shown) until the supporting flange is at a position opposite the drive flange 36 whereupon the entire assembly is moved laterally until the rotary tubular member is in registration with the supporting column 44 whereupon the bolts 3'1 are again put in place to attach the flanges 35, 36 and 40. The bolt 24 is again put in place to secure the upper bearing in fixed position and the set screws 33 and 9| are again tightened upon the rotary tubular member whereupon the device is again ready to be placed in operation. It will be obvious from the foregoing that the collapsing and erecting of my device is extremely simple and can be accomplished Yby one person in a short period of time. Furthermore, owing to the fact that none of the parts of the device Vhave to be disassembled or removed except the anges above mentioned and the bolts and set screws, nothing is likely to become lost or misplaced.
