VThis invention refers to such printedmatters as maps, diagrams, schedules, tables, drawings, etc. which are generally-too large tobe handy when they are unfolded, and unsurveyable when' they are divided into sections of smaller size and collectedin book form. I

As maps are the most important group of articles, to which the invention lis applicable, the following description and illustrations will refer only to maps. The corresponding application to other matters is obvious and selfexplanatory.

As large maps are not handy to use when touring, walking, hiking, etc., it has already been proposed to cut a map into sections along horizontal, that is West-East, and vertical, that is North- South, lines and to vbind these. sections into a book so that sections correlated in a horizontal directioni. e. perpendicular to the Vbackof the book will lform a set of consecutive pages follown-ing one another in order from West to East while. the sets of pages corresponding to the various horizontal rows' of sections follow in order from North to South. v

Pages which are correlated in westerly or easterly direction are easily Vfound by turning over thejp'ages'forwardly or backwardly. In order toA facilitate the finding of pages correlated in northerly or` southerly direction the pages are numbered and the' respective numbers of correlated pages are quoted at the margin at the topand/o'r bottom' of the page.V It is thus possible to ascertain the page number of a correlated page and to turn to this page. Usually the atlas is supplied with asurvey or leading map in the front ofthe book, which serves to facilitate finding a desired section. In some cases there has been provided a ,visual index, fully visible only from the leading map; In such an arrangement only one of the correlated sections is visible and seizable from the vsection exposed whereas the other section is only available after turningrback to the leading map.

According to my invention the leaves are provided at their edges with tabs forming nger grips so arrangedand combined with markings or signs4 for indicating the finger grips of adjacent sections correlated in a direction parallel with the back of the book, that each section, having two adjacent sections in the direction last mentioned, will'have a marked ringer grip on each side of the back of the book by means of which each of said adjacent sections is directly accessible from the section exposed.

Fig. 1 shows a modification of the invention. Fig. 2 shows a second modified form of the invention.

Figs. 3, 4 and 5 disclose a third modification of the invention. v

In the accompanying drawings which illustrate three embodiments of the invention, Figure l shows a form in which each leaf isprinted on 5 both sides, the pages 2 and Bbeing open at once, as are also pages 4 and 5 and so on. Pages 3 and l` represent the opposite sides of the same leaf, front and back, and have. therefore the 'same tab; so also pages 5 and 6, 7 and 8, and so on.

If the user has to follow a road which passes the border of a section in westerly or easterly direction, passing the left or right border respectively, it is only necessary to turn to the next page or to the preceding page, for instance, in travelling from'the town A on page 10 to the town B on page l'fl and further to the town Eon page 12.

When leaving a section in a northerly or southverlyldirectiomfor instance, when travelling from B on page 11 to C on page 1'7, there is rst to be 'Z'Oi observed the location of the tab at the edge of page 11. Thereafter there is found the next leaf having a tab at the same location which is then exposed by putting a finger on the tab and turning over the intervening leaves. When following a road to the North, for instance,l from Eon page 12 to F on page 6, the corresponding preceding rpage having a tab atr the same location will be similarly accessible after lifting the tab of page 12. Thus, in this case the tabs of the section exposed will form themselves the markings above referred to.

' In order to vfacilitate travel in this direction, North toSouth, there may be indicated, by means of an arrow or some other sign, what page is to be turned over in order to arrive at thefpage sought. When travelling from 'B on page 11 to C on'pag'e 1'7, it will be observed that'thearrow ony page 11 is located at the middle of theedge. The next page with a tab at themiddle of the edge is page 15 which should be turned over, thus exposing page 17.

It is obvious Athat instead of providing a separate section of the map on each page as inthe embodiment described, each pair of pages which are open at once may contain a single uninterrupted section covering both pages and folded along the back of the book.

Figure 2 shows a vmodification of the kind last mentioned. 'I'he sections are numbered 1 to 16. In this case the number of tab locations has been chosen greater than the number of sections or pair of pages in one horizontal strip, West-East.

, 'I'hus one strip has been divided into four sections,

but the tabs are located at six different places.

At the edges of the pages there are provided signs, such as S and N (South and North, respectively), or it may be some other sign or indication, which leads in some way to the iinger grip or tab to be used in exposing the correlated section. Thus, if the user desires to travel in northerly or southerly direction, it is only necessary to grip the tab opposite the sign in question, to the right when going south and to the left when going north, to retain the relative page and to turn over the intermediate pages.

In order to obtain suiiicient space for each finger grip it is usually required to use two or more series of tabs the tabs of each Series being distributed along the whole length of one edge of the pages. The tab division may vary but it should be seen from the description of the two embodiments described that in using a number of tabs in each series which is larger than the number of page sections or pairs of pages, or the largest number of sections respectively, in one horizontal strip, the tabs of adjacent sections will always be directly accessible from the section exposed, whereas in case the number oi tabs is equal to the number of sections or pair of pages of a horizontal strip, as in Figure 1, the tabs of sections correlated in a vertical direction will cover each other. The system of tab division used in Figure 2 may, of course, be applied to the embodiment shown in Figure 1, in which case there may be for instance four tabs in each series, i. e. one more than the number of sections or pair of sections in a horizontal strip.

Figures 3, 4 and 5 show a modification in which the tabs are provided at the upper and lower edges of the pages. The book in this case contains nine sections forming together a map cut into three horizontal strips. In the upper picture of Figure 3 the book is opened to show the rst section, in the middle picture to show the ninth section and in the lower picture to show the fifth section. The numbers of the various sections are marked on the corresponding upper and lower tabs for facilitating the finding of any particular section after a glance at a leading map. As there is only one series of tabs at the upper and at'the lower edge respectively the numbers of all sections will be seen from each section exposed as well as from the leading map. The correlated north section will be reached by means of the upper tabs and the south section by means of the lower tabs. By using signs such as N and S placed opposite the tabs of the correlated sections the section wanted can be found andV exposed at once by putting the finger on the tab so marked and turning over the intervening pages.

Obviously the invention may be applied to books of other contents consisting of sections which form together a larger area, over which one may want to follow certain lines in diierent directions.
