CarouselIn 1871, the first U.S. patent for a carousel was issued to Willhelm Schneider of Davenport, Iowa (117,336). It was described as a two-story "'carrousel' or rotary pavillion used in public parks or other places of amusement." A staircase within the central supporting frame enabled access to the upper story. Radial partitions could provide separate "apartments" with a sofa, imitation horse or other seats. It could be turned by a person or other apparatus. However, it was not very practical or successful*. Carousels had been popular for a long time. The earliest* on record was at a fair held at Philippopolis, Turkey on 17 May 1620. The first* on record in England was at the St. Bartholomew Fair in 1729. |
