Synopsis

Patents For Inventions. Abridgments Of Specifications by Patent Office is a 19th-century reference work that compiles abridgments of patent specifications, focusing on umbrellas, parasols, and walking sticks from 1780 to 1866. The edition, printed in London in 1871, presents a prefatory overview by the editor B. Woodcroft and an extensive introduction surveying the historical development of umbrellas and sunshades from antiquity to modern times. The main body comprises abridgments of individual patent specifications, listing dates, inventors, and summary descriptions of improvements in umbrella and parasol frames, ribs, joints, covers, and walking-stick mechanisms. The volume also includes an index of names, an index of subjects, and appendices pertaining to patent law (1852 amendments) and descriptive indexes. This compilation serves as a valuable resource for historians of technology and patent scholars, illustrating the evolution of materials (whalebone, cane, steel, gutta-percha) and manufacturing processes across the period.
