Gladstone bag  A Gladstone bag is a small portmanteau suitcase built over a rigid frame which could separate into two equal sections. Unlike a suitcase, a Gladstone bag is "deeper in proportion to its length." Gladstones are typically made of stiff leather and often belted with lanyards. The bags are named after William Ewart Gladstone (1809–1898), the four-time Prime Minister of the United Kingdom. Hinged luggage was first developed in the mid 19th century. One of the first recorded official documentations of the Gladstone bag is a British patent registered by Edward Cole. Edward Cole was a leather case maker based at No. 9 Hemmings Row, City of Westminster. The Patent for "An Improvement In The Frames Of Traveling Bags" was registered by Edward Cole on 4 February 1854 and sealed 14 July 1854. This original patent is still held by Cole Brothers of England in their archive. The business of Edward Cole was taken over and run by two of his sons James and Edward at the end of the 19th Century and subsequently changed to Cole Brothers in 1907, being located at 24a Floral Street, Covent Garden after the earlier demolition of the Hemmings Row site in 1886 to make way for the extension to the National Gallery. The Gladstone bag should not be confused with the attaché case-styled red box (also called a dispatch box or ministerial box) which is issued to British Cabinet Ministers to carry official paperwork. Red boxes are made by Barrow Hepburn & Gale, and the pattern of the two styles is totally different. When he was Chancellor of the Exchequer, Gladstone used a red box to carry his 1853 Budget Speech to Parliament. The travelling case to which his name is now attached was not patented until the following year. It has a frame with an opening top, rather than the book-type opening on a spine featured on the red box. By the end of the 19th century, the Gladstone bag had been adopted by doctors to carry their medical equipment. Gladstone bags were also used by the pursers on the RMS "Titanic" to carry valuables.
