Title: Improvements in amusement apparatus
IPC: A63G1/24
Filed: 1922-06-07
Abstract: 181,367. Boldizzoni, T. June 11, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Roundabouts.-An amusement apparatus consists of a rotating platform carrying a number of cars that are given irregular movements, the extent of which can be controlled partly by an attendant and by the occupants of the cars, means being provided for enabling the cars to be replaced by others of a different character. The platform 14, Figs. 1 and 2, rotates about a central standard 2 and is supported by wheels 10, freely mounted on shafts 8, which run on a circular track 4. Motors 13 drive the wheels 10 and thus rotate the platform. Tubular members 27, mounted on the shafts 8, have arms 29 carrying wheels 30 which run on a track 3 parallel with the track 4. This track is made up of linked sections 31, as shown in Fig. 3, and is normally level, but by turning the hand-wheel 45, the track is made undulatory, and the member 27 is rocked as the platform rotates. A journal 49 projects upwards from each such member 27 through an opening in the platform and a sleeve 50 rotatable in the journal 49 supports the passenger-carrying cars. The sleeve 50 can be oscillated on the journal by a roller 56 which makes contacts with other rollers 65, 66, carried by two rings surrounding the standard 2. The two rings can be turned relatively to one another by means of a handle 69, so that the attendant can vary the extent of the oscillation of the sleeves 50, and therefore the cars, about the journals 49. The cars 81, Fig. 10, are secured to the sleeves 50 by latches 93 controlled by pedals 96. By depressing the pedals, the passengers can free the car from the sleeve and thus permit the car to rotate irregularly upon the sleeve. These cars may be replaced by boats, which may float in water contained in an annular tank secured to the platform 14, the tank being so constructed that it may be assembled or taken apart quickly. Imitation motor-cars may also be used, the connection to the sleeve 50 being such that where the steering- wheel is turned the car is bumped and moves erratically on the platform 14. Another form of car, shown in Fig. 14, consists of a circular seat 101 mounted on castors 102, pairs of cars being connected by links 108 to hubs 106 that are secured to the sleeves 50. Pedals under the control of the passenger control a latch which clutches the links 108 to the hub 106, so that the passengers can control to some extent the movement of the cars. The seats 101 may be rotatable on their supports and spring buffers may be fitted around the edges.
