J. QUARTZ CARBON BINDER Dec. 3, 1929.

Filed March 14. 1928 ners 22a of the ribbon copy sheet are inserted through said slits and lie under the cover sheet at the corners thereof and the sheet thus is held in alignment with the carboncopy sheets during the" use of the binder. The paper ysheets can be placed in and on the binder by an oiice boy or other low-salaried employee and will be retained in posi?Y tion prior to` use by the typist, thus saving the time of the typist.

In the modification shown in Figs. 3 and 4, the cover sheet 14a of the binder is provided with a slit 24 which lies parallel with, and adjacent to, the stitched margin of the binder and is of a width at least equal to the width ofthe ribbon-copy sheet and less than the width ofthe cover sheet and lies entirely within the cover sheet.` One entire margin of the ribbon copy sheet 22b is-adapted to be inserted through the s/lit and lies under the cover sheet and bears against the stitchedmargin of the binder, thus to be held in alignment with the carbon copy sheets.

With the arrangementv shown, the`binder presents no obstacle to the yfree passage of the entire binder about the p laten of a type-A writer.
