Description: I offer a collection of over 1400 (!!!) patents around railway /railroad / locomotive signal technique (also including signal lamps / lanterns) from USA between 1841 and 1899. All patents are complete, that means contain the full text (including inventor/owner name, city, country) and all drawings (see example). The amount of the material is more than 4000 pages!! The patents are busy mostly with railway signal technique. Here are some patent titles which should give an imagination about the content: IMPROVEMENT IN RAILWAY-SIGNALS IMPROVEMENT IN ELECTRIC SIGNALING APPARATUS FOR RAILWAYS IMPROVEMENT IN ELECTRIC RAILWAY-SIGNALS IMPROVEMENT IN TIME-SIGNALS FOR RAILROADS IMPROVEMENT IN RAILROAD SWITCH-SIGNALS IMPROVEMENT IN LAMPS FOR BURNING HYOROCARBON OILS FOR RAILWAY-SIGNALS IMPROVEMENT IN DETONATING RAILROAD-SIGNALS IMPROVEMENT IN SIGNAL-LIGHTS FOR RAILROAD-CARS IMPROVEMENT IN RAILROAD-SIGNALS IMPROVEMENT IN RAILWAY-SIGNALING APPARATUS IMPROVEMENT IN PNEUMATIC RAILWAY-SIGNALING APPARATUS IMPROVEMENT IN RAILROAD-SIGNALS IMPROVEMENT IN RAILWAV TIME-SIGNALS IMPROVEMENT IN CIRCUIT-CLOSERS FOR RAILWAY-SIGNALS RAILROAD SIGNAL LANTERN IMPROVEMENT IN RAILROAD-SWITCH SIGNALS IMPROVEMENT IN RAILROAD-SIGNALS IMPROVEMENT IN TIME-SIGNALS FOR RAILROADS IMPROVEMENT IN ELECTRIC RAILWAY-SIGNALS IMPROVEMENT IN CIRCUIT-CLOSERS FOR RAILROAD-SIGNALS Delivery is as pdf-file collection (*.pdf) on CD (not as printed book!). Each file contains one complete patent. You need only the wellknown free programme Acrobat Reader or a similar one to open the files. You can also print each file. If you take for example "antique style paper" you can make nice pictures for wall decoration for yourself.Also included is an Excel list (*.xls) with patent numbers, datas of issue and patent titles (sometimes shortened). The list is linked directly to the patent files so that each patent will be open easily if you click on the link. This is a very comfortable way to exploit the extensive document material. It is not really a problem if you do not have the programme Excel from Microsoft. Look for "Excel Viewer" at google and you will find freeware version of an Excel Viewer programme or use any other open office programme. So you can open and print the Excel table without problem!
