Application mea Aprn 5,

My invention relates to visible index books which comprise a plurality of sets of record slips or leaves removably held by binder posts in graded form` with their lower edges '5 feathered so that a portion of the edge of '2b book is opened and these telescoping sections spread apart said posts will be likewise spread apart more or less as desired, whereby the slips may be readily thrown from one set of posts to the other or may be removed and suitable insertions made.

This invention is closely identied with the invention shown and described in my pending application, Serial No. 222,457, filed September 28, 1927, and the particular object ofthe presentl invention is to render the pivoting of either of the two series of `the leaf-carryingk parts entirely unnecessary, and

' to so arrange these parts that they are rigid and are capable of being spread apart by two successive sliding movements, the first of' which follows the opening of the book and the spreading of the telescoping sections to place the binder in shape for the usual manipulation of the sheets from one side to the other with the'parts always engaging wit-hin the perforations in the sheets. The other or finall sliding movement of thetwo series of posts, is brought about by extending the outward sliding movements of said sections to their limit so as to separate the ends of one series of posts from the ends of the other series, leaving a space between said ends amply suflicient to permit of the ready withdrawal or insertion of sheets.

@ne series of posts is capable of lengthwise shifting movements so that additional sheets 1928. Serial No. 267,515.

may be placed at the top or bottom of a series i yof sheets, or a sheet inserted between twov other sheets, this characteristic being fully shown and described in my aforesaid pending application, and therefore no novelty is claimed for this feature.

In the accompanying drawings which form a part of this application Figure 1 is a plan view of theinside of the book, with the interleafers and slips removed, and showing the back sections closed and the parts in their normal condition.

Figure 2 is a sectionat the line 2 2 of Figure 1.

Figure 8 is a section at the line 8 3 of Figure 1.

Figure 4 is a view similar to Figure 1 but showingthe back sections initially spread, so that the sheets 4may be manipulated from one set of posts to the other set. l

Figure 5 is a section at the line 5 5 of Figure 4.

Figure 6 is an inside view showing the sections spread to their limit and one set of posts shifte v Figure 7 is a section at the line 7 7 of Figure 6. I f y Figure 8 is a section at the line 8 8 of Figure 1.

Figure 9 -is avsection at the line 9 9 of Figure-4, and A Figure 10 is a section at the line 10-10 of Figure 6.

Similar numerals of reference denote like parts inthe several figures of the drawing.

The drawings do not show any record slips or interleafers in position on the posts, since the object of visible index books and the manner of manipulating suchA slips and interleafers are so well known that illustrations in these respects are deemed unnecessary. i f

1, 2are telescoping metallic back sections, such as are common in loose leaf ledgers, and 8, 4, are the side covers which carry spaced hinge eyes 5, 6. Y

The sides 7 8, of the sections 1, 2, are at right anglesto the back portions and have at spaced intervals alongutheir edges hinge eyes 9, 10, the'hinge eyes of the covers and these sides being alined and pintles 11, 12, passed through them whereby the covers are hinged to the sides.

The section 1 has rectangular ends 13 that terminate in inturned flanges 14 which are disposed in telescoping relation beneath similar inturned flanges 15 at the ends 16 of the section 2.

17 is a shift bar whose lower edge has lugsk 18 that track within elongated slots 19 in the back portionof the section 1, the upper edge of this bar having formed therewith at spaced intervals eyes 2O through which the pintle extends, and the portions of the latter embraced by the eyes are longer than said eyes, so that it will be clear that the bar 17 may be shifted lengthwise. 21 is one series of parallel posts secured to the bar 17 and extending toward the sec` tion 2 and in parallelism with the backs of the sections.

Confined within the side y8 of the section 2 by means of an elongated strip 22 is a slide 23, this strip being spaced from the side 8 to provide a runway for the slide and having at its upper edge hinge eyes 24 alined with the eyes 6 and 10 and surrounding the pintle 12, the lower edge of this strip having inturned portion 25 that abuts the slide 23 to keep it in place. 21 is a series of posts rigidly secured to the strip 22 and extending toward the posts 21 in parallelism and in spaced rela tion thereto. Elongated slots 27, 28, are formed in this slide 23, and through these slots screws 29, 30, are driven from the strip 22 into the side 8, the object of thisbeing to secure the strip to said side and to permit the free lengthwise movements of the slide 23, and at the same time to cause the portion 25 to stillen the strip.' The slide 23 has at its lower edge flanges 31, 32, that extend inwardly parallel with the back of the section 2, and slightly spaced therefrom so as'not to interfere with the back of the section 1 when the sections are telescoped in closed position.

33, 34, are links whose extremities are respectively pivoted tothe flanges 31, 32, and to the back of the section 1, so that it lwill be understood that when said sections are spread these links will operate to throw the slide 23 outwardly thereby causing the flanges 31 and 32 to travel with said slide. Pivoted at 35 to the upper corner of the front end of the slide 23 is a bell-crank lever 36, whose outer end terminates in a finger grip 37, whereby the lever and consequently the slide may be pulled outwardly. The inner or lower crank portion of this lever 36 is connected to the slide 23 by means of a coiled spring 38 which functions to normally throw the main lever that carries the linger grip downwardly against the adjacent end 16, and a notch 39 is cut in the bottom edge of this lever which notch engages the end desired to spread the sections to their limit the operator merely lifts the bell crank so as to disengage the notch and then by means ofthe linger grip pulls the slide outwardly to-bring the parts into the position shown at Figures 6 and 7.

The normal position of the parts of the book is wit-h the sections closed, as is shown at Figure 1, and the links 33l and 34 will be parallel with the sides 7, 8, and the slide 23, with its flanges 31, 32, will be at the extremity of its inward adjustment and the linger grip 37 will be against the'end 16.

In order to place the book in condition for convenient manipulation of the slips and interleafers that are threaded on the posts, the operator, after opening the covers, grasps the sides 7, 8, and pulls them apart thereby causing the slide to be thrown outwardly until it is arrested by the engagement of the notch 39 with the end 16 of the section 2, and when the sections are in this position, as is shown at Figure 4, it will be observed that the ends of the posts are in overlapping relation with respect to each other so that the slips and interleafers may be readily manipulated from one side of the book to the other without danger of the .perforations in such` slips and interleafers leaving the posts. The sections of the book are closed by merely pressing them together.

`Whenever it is desired to remove any, slips from the book or to introduce additional slips, the operator, after spreading the sections to the position shown at Figure 4, lifts the protruding bell-crank and by means of the finger brought into the position shown at Figure 6,

it is merely necessary to thrust the bell-crank inwardly to its limit until the finger grip 37 abuts the end 16.V

The links not only function to permit the proper spreading and contraction of the sections when the slide is operated but they also serve asa means to prevent the sections from` spreading beyond the proper limit such as might cause their disengagement entirely.`

rlhe insertion of slips intermediate of other slips is very. readily affected since it is merely necessary to bring the sections to the position shown at Figure 4, move all of the slips to the right onto the posts 21, shift the bar 17 with the post 21 and the slips, then part the slips at the place where the insertion is to be made, throwing one of the parted portions to the left of the book, spread the sections fully to the position shown at Figure 6, then insert the new slip in its proper place with its edge immediately above the top slip at the right of the book, shift back the bar 17 to its normal position and close the book.

Having thus described my invention what I claim is 1. A visible index book, comprising sections whose backs and ends are disposed in slidable relation, posts carried by the sides of said sections in normal parallelism with each other and with the backs of said sections, and means for automatically limiting the initial spreading of said sections to partially open position, said means being manually operable to permit the spreading of the sections to their limit.

2. A visible index book, comprising a back of telescoping sections, a series of straight leaflcarryingposts rigidly secured to one of said sections anda series of similar posts mounted on the other section so as to be shiftable lengthwise, both sets lying in parallelism with the backs of the sections, and means carried by one section for automatically limiting the initial spreading of said sections to partially open position,said means being manually operable to permit the sections to be spread to their limit.

3. A visible index book, comprising a back of telescoping sections, a seriesof straight leaf-carrying posts rigidly secured to one section in parallelism with the back thereof, a bar carried by the other section and adapted for limited longitudinal sliding movement, a series of straight leaf-carrying posts rigidly secured to said bar and extending toward the first-mentioned series of posts in parallelism therewith and in staggered relation thereto, and means serving to limit the extension of said sections to definite successive stages.

4. A visible index book, comprising two telescoping back sections, a series of leafcarrying posts rigidly carried by one section in parallelism with the back thereof, a shift bar carried by the other section and conlined except as to sliding movements, a series of leaf-carrying posts rigidly secured to said bar and extending toward the first series of posts in parallelism therewith and in stag- -the other series.

5. A visible index book, comprising two telescoping back sections, a series of leafcarrying posts rigidly carried by one section in parallelism with the back thereof, a shift bar carried by the other section and operable between prescribed limits, a series of leafcarrying posts rigidly secured to said bar and extending toward the first series of posts in parallelism therewith and in staggered relation thereto,-slidable elements within the firstnamed section and capable of movement lengthwise thereof, links pivotally connecting said elements with the other section, and a notched resilient bell-crank lever pivoted to one of said elements and adapted for automatic engagement with a stationary part to limit the initial spreading of the sections, said means being manually operable to relase said engagement and thereby permit the full spread of said sections.

6. A book for visible indexes, comprising two telescoping sections, a series of straight parallel posts rigidly carried by each section in spaced relation and in a plane that is parallel to the backs o-f said sections, and means for automatically limiting the spreading of said sections to two definite stages.

7. A construction as in claim 6, further distinguished in that the lirst stage brings the ends of the posts of each series in overlapping relation whereby the sheets carried thereby may be manipulated from one side of the book to the other, while the second stage spaces the posts of one series from the posts of the series in the direction of their lengths, whereby sheets may be removed from or inserted on said posts.

In testimony whereof I aix my signature hereto.
