The technology is still used on a smaller scale. It was once envisaged that networks of massive tubes might be used to transport people. While they are commonly used for small parcels and documents, including cash carriers at banks or supermarkets, in the early 19th century, they were proposed for transport of heavy freight. A tube was laid between the Aberdeen fish market office and the main post office, to facilitate the rapid sale of the very perishable commodity. ![]() By 1880, there were over 21 miles (34 km) of tube in London. That expansion was due to Joseph William Willmot (previously employed at the Electric & International Telegraph Company) improving Latimer-Clark's invention in 1870 with the "double sluice pneumatic valve" and, in 1880, the "intermediate signaller/quick break switch for pneumatic tubes", which dramatically speeded up the process, and made it possible for a number of carrier messages to be in the tube at any one time. After the telegraphs were nationalised in Britain, the pneumatic system continued to be expanded under Post Office Telegraphs. In the mid-1860s, the company installed similar systems to local stock exchanges in Liverpool, Birmingham, and Manchester. The advantage of the pneumatic system was that, without it, the company would have had to employ runners to carry messages between the two buildings, or else employ trained telegraph operators within the Stock Exchange. The Electric Telegraph Company used the system to acquire stock prices and other financial information to pass to subscribers of their service over their telegraph wires. In 1853, he installed a 220-yard (200 m) pneumatic system between the London Stock Exchange in Threadneedle Street, London, and the offices of the Electric Telegraph Company in Lothbury. In 1854, Josiah Latimer Clark was issued a patent "for conveying letters or parcels between places by the pressure of air and vacuum". The system is known as pneumatic dispatch. Capsule pipelines were first used in the Victorian era, to transmit telegrams from telegraph stations to nearby buildings. Pneumatic transportation was invented by William Murdoch around 1799. Ī small number of pneumatic transportation systems were built for larger cargo, to compete with train and subway systems. However, they have been further developed in the 21st century in places such as hospitals, to send blood samples and the like to clinical laboratories for analysis. ![]() Some installations became quite complex, but have mostly been superseded. In the late 19th and early 20th centuries, pneumatic tube networks gained acceptance in offices that needed to transport small, urgent packages, such as mail, other paperwork, or money, over relatively short distances, within a building or, at most, within a city. They are used for transporting solid objects, as opposed to conventional pipelines which transport fluids. Pneumatic tubes (or capsule pipelines, also known as pneumatic tube transport or PTT) are systems that propel cylindrical containers through networks of tubes by compressed air or by partial vacuum.
