Patented Dec. 3, 1940 UNITED STATES 2,223,642 SLIP-INDEX FOLDER George W. Shaw, Muskegon, Mich., assignor to The Shaw-Walker Company, Muskegon, Mich.', a. corporation of Michigan Application October 29,1938, Serial No. 237,671

8 Claims.

This invention relates to a slip-index folder, and consists of the matters hereinafter described and more particularly pointed out in the appended claims.

The object of the invention is to provide a slipindex folder adapted to be made from a single blank which comprises back sections and an interposed plurality of narrow index guides between which the slips may be inserted as desired, said index guides maintaining the slips as if in separate compartments.

Another object of the invention is to produce a slip-index folder which is of economical construction and which may be manufactured at 5' small cost.

The advantages of the invention will appear more fully as I proceed with my specification.

In the drawings:

Figure 1 is a view showing the improved slipindex folder as it appears with slips therein and partially open.

Figure 2 is a view representing the folder containing the slips opened out flat on its back.

Figure 3 is a perspective View showing the 5 folder with slips therein, and particularly the back expanded edge of said folder.

Figure 4 is a view showing asection through the folder filled with slips, in a plane indicated by the line i -4 of Figure 1.

30 Figure 5 is a plan view of a blank made of a sheet of heavy paper or light cardboard, cut and scored to form the folder.

Figure 6 is a perspective view showing the blank partially folded.

Figure 7 is a perspective view of the blank more closely folded with the index-dividing members spread out fanwise to show how they divide the space within the folder to receive the slips the folder is to contain.

Referring now to that embodiment of the invention illustrated in the drawings: ID in Figure 5 indicates the blank for forming the folder. It

is made of a sheet of comparatively stiff paper or light cardboard and is of horizontally elongated rectangular form. It is cut to provide like front and rear rectangular vertical back sections II and [2. Each back section has a laterally projecting tab Il l2", respectively,-

50 the tab II being located at the top of the front back II, and the tab I 2 being located at the bottom of the rear back [2. II and I2 indicate fold lines, respectively defining the inner edges of the back sections II and I2.

55 Intermediate the fold lines H and I2 is a and bottom to points If: and I6, respectively, on

the fold line I14, which are substantially in horizontalv alignment with the bottom and top, respectively, of the tabs ll and H The section I3 of the blank is cut or slit through on horizontal parallel. vertically spaced lines. ll crossing the fold line l4 at equally spaced points on that line, and extending to the fold lines ll li In this case nine of such spaces are used, thus dividing the section I3 into nine separate parts, each foldable upon itself about the 20 line I4: l9 indicates notches above the slits or cuts .l'i' extending laterally fromthe fold lines ll I2 Above and below said series of notches the fold lines Il l2 are scored.

To bring the blank into folder form, theback sections II and ii are folded along the lines N and I? towards each other, and the intermediate section i3 is folded on the line H in the reverse direction, as shown in Figure 6. The folding is continued until the back sections are brought together with the parts of the intermediate section l3 in contact with each other and interposed between said back sections. The intermediate section l3 thus folded between the back sections presents a plurality of narrow index guide memb ers l3 which are duplex in form, as shown in Figures 1 and 2. They may be fanned. out as shown in Figure '7, and separated when required toinsert slips between them into the folder. The notches l9 provide greater freedom of move- 40 ment between the index guide members when swinging them apart to define associated pockets in the folder. The guide members are provided at their outer ends with index characters of any kind desired, as for example numerals in this case. In order to accommodate the expansion of the folder with the insertion of slips between the index guide members, the back sections II and I2 are provided with score lines at an angle 5 to the fold lines Il l2 the one diverging slightly from the top to the bottom as indicated at l I, and the other diverging to the same extent from the bottom towards the top as indicated at 12. On account of this construction, the folder 55 when filled will assume on its rear edge the shape indicated in Figure 3, with the fold lines ll l2 following a diagonal line from the bottom end of the score line l2 to the top end of the score line ll, as shown in Figure 3.

The manner of use of the improved slip-index folder will be obvious from the foregoing description and from an examination of Figures 1 and 2. The index guides extend beyond the edges of the back sections of the folder where they are exposed as index tabs ofiset from top to bottom in line with the tabs Il l2 of said back sections. The desired index tab is thus readily grasped for opening the folder to insert 7 (or remove) a slip or slips in proper relation to an index guide. And said index guides will maintain the slips in the folder in the classified, separated relation denoted by the index char acters on the exposed tabs of the index. guides, as shown in Figure 1. L

I claim as my invention: I

1. A slip-index folder formed from a single blank cut and scored to provide laterally spaced back sections and an intermediat section foldable upon each back section and foldable midway between said backs upon itself, said intermediate section being slit upon a plurality of horizontally spaced lines to provide narrow duplex index guides independently hinged between said back sections.

-.2..A slip-index folder. formed from a single blankpcut and scored to provide laterally spaced back sections eachhaving a laterally projecting tab, one being at the top and the other being at the bottom of the blank, and an intermediate section equal in width to the combined width of said back sections in the zone of said tabs, said intermediate section being foldable upon each back section, being foldable midway between said backs upon itself, and being slit along a plurality of horizontally spaced lines to provide narrow duplex index guides independently hinged .between said back sections.

3. A slip-index folder. formed from a single blank ,cut .and scored to, provide laterally spaced back sectionsand an intermediate section foldable on each back section and foldablemidway between said back sections ,upon itself, said intermediate section .being, slit upon a plurality of horizontally spaced lines to provide narrow duplex index guides independently hinged between said back sections, said index guides being provided with elongated notches above said slits extending from the line of fold between said back and-intermediate sections.

4. A slip-index folder formed from a single blank cut and scored to provide laterally spaced back sections and an intermediate section foldable upon each back section and foldable midway between said back sections upon itself, said blank being provided with diverging lines of weakening adjacent the fold lines between said sections,

5. A slip-index folder formed from a single blank cut and scored to provide laterally spaced back sections and an intermediate section foldable upon each'back section and foldable midway between said back sections upon itself, said blank being provided with diverging lines of weakening adjacent the fold lines between said sections, the divergence in one case being towards the top of the blank and in the other being towards the bottom of the blank, said intermediate section being slit upon a plurality of horizontally spaced lines to provide narrow duplex index guides hinged between said back sections, and being provided with elongated notches above said slits extending laterally from the fold lines between said sections. 3

6. A slip-index folder formed from a single blank cut and scored to provide laterally spaced back sections, each having a laterally projecting tab, one being at the top and the other being at the bottom of the blank, and an intermediate section equal in width to the combined width said section and in horizontal alignment with the top and bottom, respectively, of thetabs on said back sections, and 'said intermediate section bein slit along a plurality of horizontally spaced lines to provide narrow duplex index guides independ-f ently hinged to said back sections. 7 I

7. A slip-index folder comprisingback sections and a plurality of narrow, horizontally elongated duplex index guides, each part of each guide being independently hinged to an associated back section, and said index guides projecting beyond the free edges of said back sectionsto present tabs for index characters. I V M 8. A slip-index folder comprising back sections hinged together, one back section having a lat-.

erally extending tab at thetop, and" the other having a laterally extending 'tabQat-the bottom, and a plurality of horizontally elongated duplex index guides located between said sections,'each part of each guide being independently hinged to.

an associated back section, and said index guides projecting beyond the free edges of said back sections to present tabs for index characters offset in line with the tabs on said back sections.
