Abstract: 22,916. Johnson, W. O. Oct. 28. Book - keeping ; indexing.-A card-index and letter and document file comprises a number of record sheets A, Fig. 1, for accounts &c., and a number of pockets or folders Z for receiving letters and documents in connexion with the record sheets, segregated into a series of groups by means of a number of index sheets B, H, &c., each group of record sheets having index tabs or projections of distinctive appearance and corresponding to those on a companion group of pockets or folders. In the arrangement shown in Fig. 1, the record sheets A, each having a white tab, and the folders Z, each having a black tab p, are divided into groups by the index sheets B, H, &c. with 31 record sheets and 31 folders in each group, the first 10 record sheets having been turned over out of sight for convenience of illustration. Each record sheet is provided with a column C divided into 31 parts, as shown. The index sheets are provided with a column D for names, columns E, F for the numbers of the accounts, and a column G for check marks ; either of the columns C, E may be dispensed with. The parts of the column F are numbered from 1 to 31 on the first index sheet, 32 to 62 on the second, and so forth, the inclusive numbers being given on the tab of each index sheet. Each pocket or folder consists of a doubled piece open at the top, or an envelope &c. having a number column similar to the column C, any record sheet or folder being found by means of the white or black tab in line with the name and number on the index. To enable the index sheets to be raised and lowered, each index sheet H, Figs. 3 and 4, is attached to a guide-board I having a projection K provided with a filing-eyelet L and fitting into a groove in the bottom of the drawer. A metal plate a having a depressed portion b is fastened in an opening in the index sheet H by means of rivets h, i, and a similar metal plate a' is fastened to the board I. Rivets g, g' secured respectively to the card H and board I and having washers d, d<1> provided with projections are adapted to slide in vertical slots in the metal plates. The index sheet is supported in its raised position by the projections on the washers entering horizontal grooves f in the plates a, a<1>. The metal plates may be dispensed with. In a modification, the index sheets are of the same height as the record sheets, and are placed in front of the corresponding groups of record sheets and folders, the inclusive numbers being placed on separate sheets or guide-boards. Tabs of different colours, markings, or shapes, and marked with the month &c. are placed upon the record sheets and folders to draw attention to dates of importance in connexion with the accounts. The record sheets and folders may each be classified or indexed separately in different parts of the same drawer or in different drawers, and when used as a file, the folders or division sheets of the file may lie flat and have the index sheets and tabs along one side instead of along the top edge. Extensions of the record sheets may be used in place of tabs. The tabs are made of a piece of metal having one end cut into three prongs or tongues for grasping the sheet.
