Card Shuffler, 1937

Social Security Board Records Office, 1937. From LOC: "Baltimore, MD. Strange as it may seem, many persons misspell or change the spelling of their names, from time to time. To forestall the difficulties which would ensue when Baer subsequently spelled his name Bear, the Social Security Board Records Office has set up several varieties of indexes for reference and to insure accuracy. One of these is the alphabetic code index. This is printed on flexible strips, each just wide enough for one line of type. They are printed automatically from the employee master card. The strips are in partially perforated rolls when they first are printed, as shown in the above photograph taken in the Records Office. The perforations allow strips to be separated at any point so that, for example, Abraham Abel's name may be inserted in proper alphabetic sequence between Aaron Abel and Adam Abel."
