Along a blank wall space are hinged to the wallmetal or wooden wings, to which sets of prints, corresponding to thetracing classifications, and fastened together by special binders, are sus-pended by screw eyes and hooks. The binder carries file and setnumber and labels; it covers the brass fastening pins and inequalitiesin prints and by a method of overhanging the sets on brackets enablesan edgewise movement of the sets for perusal which leaves nothing to.

It is well to keep upseveral forms for indexing and recording drawings. One shouldbe a system of consecutive numbers recorded in books, with all therequisite information following each number. Another should be acard index of subjects, with all classes of drawings pertaining to eachsubject grouped together. As to miscellaneous data, records of pat-terns, machines, costs, employees, stock, orders, equipment, transac-tions, etc., there can be no question about the advantage of a cardindex. 526 THE ENGINEERING MA
