6897 results about "Carriage" patented technology

A carriage is a wheeled vehicle for people, usually horse-drawn; litters (palanquins) and sedan chairs are excluded, since they are wheelless vehicles. The carriage is especially designed for private passenger use, though some are also used to transport goods. A public passenger vehicle would not usually be called a carriage – terms for such include stagecoach, charabanc and omnibus. It may be light, smart and fast or heavy, large and comfortable or luxurious. Carriages normally have suspension using leaf springs, elliptical springs (in the 19th century) or leather strapping. Working vehicles such as the (four-wheeled) wagon and (two-wheeled) cart share important parts of the history of the carriage, as does too the fast (two-wheeled) chariot.
