claims.. (ci. 12s-#1) Tjhis invention relates to loose leafbinders and more particularly to binders ofthe type in which provision is made for varying their capacity. An important object of the invention is to pro- 5 vide a binder of what may be termed the doublepost unit typen which the posts are adapted to be extended in height to provide for the accumulation of sheets in the binder, the invention in its preferred form contemplating the provision of a pluralityof cylindrical post sections threadedly connected together and variable as to height by rotation of one memberV within another.

Another object of the invention is' to provide a binder in which the companion posts of each double-post binding unit are united by an arcuate connector, one end of the connector being resiliently mounted in oneI of the posts, so as to permit the connector to be raised against spring tension. and the other end of the connector having an axial projection or pilot adapted to seat,

` upon the release of the connector, in a socket carried upon the end of the other post. By this arrangement the connector may be readilydisengagedfrom the latter post and swung to outof-the-way position to allow the convenient -association or disassociation of perforated sheets with the post, and then reengaged with the pilot maintained in the socket of the post by spring pressure so as to avoid accidental displacement therefrom.

The invention has as another object to provide, in a binder of the expansible type having a bottom and a. top cover connected to a back member, which serves to protect the rear edges of the stack of bound sheets, means for increasing the width'of the back member from time to time in correspondence with variationsl in the height of thefstack of contained sheets due to the accumulation of sheets in the binder or to withdrawals 40 therefrom. More particularly this object is ac-y complished in the preferred form of my invention by hingedlyrconnecting the bottom and top covers to a back member composed' of a plurality y of rigid complementary sectionsarranged to be detachably connected atv or adjacent their longitudinal edges and permitting the insertion of V supplementary sections to expand the width of the back. The sections may be advantageously united edge-toledge by a tight'frictional tongueand-groove fit, a suitable numberl of supplemental sections being provided to allow widening the r back member tosan extentcorresponding to the4 full capacity ofl the-,binder'as vdetermined by thel 4adjustability affordedb'ythebindingrposts. An. alternative form of back member within one of. the double-post units;

of Fig. 1'

the scope of my invention contemplates forming the back of a plurality of rigid relatively shiftable sections; and providing means for retaining the sections in their different positions of adjustment. 5

` Still another object of my invention is to provide a binder having top and bottom covers of rigid construction which are extensible in a lengthwise direction to'adapt the binder to the accommodation of sheets of different lengths and 10 thus fully protect the edges ofl the slleets which would otherwise project beyond :the lower end of the binder. According to the preferred form of the invention, the covers are composed of aplul rality of transverse sections having a sliding 15 interiit one with another in a manner such that one cover section may be separated or closed together lengthwisel with respect to an adjacent section to vary the dimensions of the covers.

Other objects and advantages of the invention 20 will become apparent from the following detailed description of .typical binder constructionsl embodying the novel features of my invention, reference being had to the annexed drawing in which:

Figure 1 is a perspective view of a binder of the double-post unit type constructed in accordance with the principles ofthe invention;

Figure 2 is a detail view, in part sectional, of

' 30 cross-sectional view line l33 Figure 3 is fragmentary through the bottom cover along the Figurel 4 is a detailed perspective view of one end of a muitisection back member showing the 35 1 sections separated; and i Figure 5 is a perspective view of an alternative form of back which may be employed with the binder of Fig. 1.

The binder illustrated in Fig; 1 comprises a flat 40 vbottom cover 2li.` and a fiat top cover 2| (one end only being shown), made of rigid material such as pulpboard, having their ends hinged to a multipart back member 22 also of rigid material. The covers are of substantially identical 45 construction and mounted upon the bottom cover adjacent its rear transverse edge are a plurality of double-post units 23 arranged in'parallel intermediate the side margins of the cover, and

'each comprising two'posts 2l and 25 spaced a short distance apart lengthwise of the cover and joined at their tops by an arcuate shaped connector` 25a.

As best shown in Fis. 2, the two posts oi. each unitlare constructed exactly alike. The post 24 55 consists of a stud 26 which is oppositely threaded upon its two ends and is provided with an enlarged circumferential ring 21 intermediate its CTI ' ond cylindrical sleeve 32.

length. One end` of the stud projects through an opening 28 formed through the bottom cover and projects a suliicient distance beyond the lower surface of this cover to allow a nut 29 to be mounted upon its extended end, so that by tightening this nut the cover` is firmly clamped against the ring 21.

To the end of the stud which projects above the upper surface of the cover is connected a relatively short cylindrical sleeve 30 having a smooth circumference and its upper end being beveled inwardly as indicated atv 3l. The sleeve 30 is internally threaded throughout its 'length and arranged to travel along this thread is a sec- The sleeve 32 is of approximately the same length as sleeve 30 and is of smaller diameter than the latter so as to be snugly received within the latter. Upon the lower end of sleeve 32 is flxedly mounted an annulus 32a which isexteriorly threaded so as to cooperate with the threads upon the interior of sleeve 3D whereby by rotating sleeve 32 with the fingers the sleeve is moved inwardly or outwardly of sleeve 3i) and toward or from the upper end of stud 26 which closes the bottom of the latter sleeve. The circumference of sleeve 32 is, similar to sleeve Sil, smooth surfaced and beveled inwardly at its elevated end as indicated at 33.

As has already been stated post 25 is of exactly Vthe same construction as post 24, corresponding parts being indicated by the same reference numerals. The double-post unit thus is composed of a plurality of telescopic sleeves having a smooth circumference and of slightly diierent diameter which taper together to facilitate the passage of perforated sheets along the posts.

The two `

posts

24 and 25 of each double-post unit are joined at their tops by the arcuate shaped connector 25a, which carries upon one end a hollow stem 35, having an annulus 36 xedupon its lower end threaded to engage the screw threads upon the interior of sleeve 32 and having a cap 31 threadedly secured to the stem 35 and closing its upper end. The connector is maintained in association with the cap 31 and stem 35 by means of a pin 38 which is threaded into the bottom face of the connector at one end and which passes through anopening in the cap 31. The other end 'of the pin 38 is provided with a circular head 40 which snugly fits within the inside of stem 35 and presents a bearing surface for one end of a spring Il which surrounds the pin and is under light compression between the head and the cap.

By rotating the pin the tension of the spring may be varied. The cap has a down turned flange 42 which is interiorly threaded to engage threads upon the upper end of the stern 35 in the assembly of the parts. f

The other end of the connector is provided 'with an axially disposed cylindrical pilot 45 which slips into a socket 46 formed in the upper end of a short plug 41 which is formed with an exterior- 1y screw threaded boss at its lower end so as to engage the threads upon the interior of sleeve 32 of post`25.

It will be apparent from the construction just described that in order to place perforated sheets upon or remove them .from the post 25, it is only necessary to raise the connector 25a against the action of spring 4I a suicient distance to lift pilot 45 out of socket 46 and the connector may then be rotated to out-of-the-way position as v indicated in dotted lines in Fig. 1. To reengage the connector, it is again raised and swung back into alignment with the post 25 and the pilot dropped back into the socket 46. -The spring 4| yieldingly holds the connector in place. Apertures 49 are advantageously provided in the walls of the screw threaded parts of the unit for engagement with a, pin (not shown) to facilitate turning should the parts stick.

As sheets accumulate in the binder and the stack (indicated by dotted lines in Fig. 1) increases in height the pair of posts of the two double-post units of the binder may be extended by rotating sleeves 32 within sleeves 3l, stem 35 within sleeve 32 on post 24 and plug 41 within sleeve 32 on post 25. Thus a large amplitude of movement of the posts is aored and the binder can perform the duty of several binders of the older type, at the Same time having the advantage of compactness when it is used for accommodating only a small volume of material.

The bottom and top covers 23 and 2l are of substantially counterpart construction except for the provision of longitudinal slots U in the top cover which provide clearances for the upper ends of the double-post units, and since these units may be erected at different distances apart upon the bottom cover the slots will be sufficient in number and suitably located to anticipate changes in the locations of the double-post units.

As sheets are added to the binder and the posts are extended, the back member 22' must vbe widened to keep pace with the increasing height of the stack of bound sheets. This is accomplished by the following construction. The top and bottom covers are connected to the back member by means of spaced projections 55 formed on the end of the covers interiitting between correspondingly spaced projections 56 carried upon the longitudinal edges of end strips 51 and 58 and having pintles 59 passing through, aligned recesses extending through the projections, as shown in Fig. 1, to hinge the covers to recesses 64 upon their opposite edges, corresponding to the tongue and recess of the end strips are adapted to be inserted intermediate the end strips in the manner best indicated in Fig. 4 so as to build up the back in small increments. While it is contemplated that these strips will be held together with sufficient firmness by means of the binding it between the tongues and grooves, if desirable screws (not shown) may be passed `through openings between these parts to positively retain them in association.

Both the bottom and top covers are made up of a plurality of separable transverse sections, the three sections A, B and C composing the bottom cover 20 corresponding in all respects to the three transverse sections composing the top cover 2l. As shown in Fig. 1 the end section A of the bottom cover is hinged to the back member 22 while the intermediate section B is provided at its opposite edges with tongues 85 which snugly tit within complementary grooves 66 formed in the adjacent edgesof end sections A and C. As will be apparent from this constru( tion, the sections may be separated in a lengthwise4 manner, the-tongues 05 sliding within the tion aligned in a direction lengthwise of the covers so as to allow any one of these openings to be brought into registry with the complementary openings 1I in the tongues 65 oi the intermediate section.

A modied form of extensible back member is A illustrated in-Flg. 5. Secured t0 the bottom and top covers -2l and 2i are ilat, sheet metal inserts 15, these inserts each carrying spaced cylindrical projections 16- upon their longitudinal margins which extend beyond the end of the cover. These projections t into the spaces between complementary projections 11 carried upon the contiguous edge oi a plate 1l, suitable pintles 19 extending through the eyes of the projections -and hingingthe metal inserts and plates together.

The plates 1I which are connected to companion inserts overlie each other for a substantial distance upon their longitudinal margins opposite to Ithe margins carrying the projections 11.

and are held together by means of releasable .screws 80 passing through elongated slots Il formed in the overlapped plates. The arrangement is such that by unloosening the set screw the plates may be shifted relative to each other to widen or narrow' the back. To one of the plates 18 may be attached an index or label support B2.

It will be apparent that various other changesy in arrangement Iand design may be made in the binder constructions described above, which are to be regarded as exemplary only of preferred forms which the invention 'may take, without departing from the spirit of my invention.
