[Illustration: HAND GRAPHOTYPE WHICH EMBOSSES TYPEWRITER STYLE CHARACTERS ON METAL ADDRESS PLATES] Attachments Increase Utility of Addressograph. The first addressographs were intended for printing names and addresses consecutively on envelopes and post cards. And so much time was saved on this one application that customers soon began applying it to other kinds of work in their offices. To do this effectively, it was necessary for Mr. Duncan to work out additional parts called “attachments” which permitted the addressing, listing and imprinting of names and other data on office forms of every nature. To illustrate: the dating attachment enabled users to apply the addressograph to their statement work. With this attachment--which can quickly be thrown in or out of operation--the current date is printed at the head of a statement simultaneously with the printing of the name and address. Further, to use the addressograph effectively for statement work, it was necessary to devise a skipping attachment--manipulated by the operator’s knee--permitting him to skip the printing of impressions from address plates of those customers who had paid their accounts. By working out the listing attachment, Mr. Duncan made it possible for users to list names in one or more vertical columns on pay sheets, drivers’ route sheets, dividend and trial balance sheets. This attachment automatically feeds the paper and spaces the proper distances between the printing of each address. Then came the electric bell signal and automatic selector attachments. Users of classified lists of names were enabled by these attachments to place tabs in sockets at the top and back of the address plates to indicate the different classifications on the list, such as “Buying Seasons,” “Kinds of Products Wanted,” “Territories,” “Expired Dates,” etc., and by means of these attachments, automatically select for addressing certain address plates, skipping the addressing of others.
