2 Claims.

This invention relates to means for facilitating the addition, shifting or removal of sheets bound in a loose leaf volume andhas for its object the provision of a. new and improved device of this yp V p 7 An object of this invention is to provide a new and improved loose leaf binder which will cooperate with a sheet shiftingand changing member to permit theraddition, shifting, or removal of sheets with the maximum facility and minimum of error.

.The above as well as other objects are each attained by providing the loose leaf binder and the sheets which are adapted to be placed therein 5 with one or more apertures and providing a base member with one or more prongs adapted to be receivedin said apertures, the said prongs being formed oftwo separable elements which inone position form a continuous guide for the said sheets and in another position permit the posi-' tioning of the said binder prong elements. One of the many possible embodiments of my inventive concept is'shown in the accompanying drawings and will herein be more particularly described for the purpose of illustrating my invention.

upon the said separable In the drawings Figure 1 isa top view of my novel unit in operative position upon a support. Figure 2 is an enlarged perspective view of my novel binder in the open position, a portion bebetween the ends being broken away to permit the showing of the elements on an enlarged scale. The portion broken away is merely a repetition of the elements shown.

Figure 3 is a perspective view showing the prong carrying or sheet guide member of my novel combination. The full lines show the V prongs in their closed position when the prongs are adapted to form a continuous guide for the leaves or sheets and the dot and dash lines show the prongs in the open position when the binder may be positioned on or removed from the prongs and when leaves may be added, shifted or removed.

Figure 4 is an enlarged perspective view of a fragment constituting one of the/ends of my novel unit, the remainder of the unit having been broken away to permit the showing on the enlarged scale. The portion broken away merely constitutes a repetition of the elements herein shown. This view also illustrates some of the different positions of the respective members and elements of the unit. The full lines show the 55 prongs in the open position and the binder just 1933, Serial No. 684,508

after it has been positioned upon the prong elements adapted-to receive it. The dot and dash lines show one of the binder elements after it has been removed to permit free movement of the leaves and the prongs in the closed or active position.

Referring more particularly to the drawings wherein similar reference numerals denote similar parts reference numeral I denotes my novel unit consisting of a binder member 2 and a sheet guide member 3 which are usually positioned upon a base, support or table T.

The binder member 2 consists of a pair of parallel binding slats 4 and 5 each of which carries a plurality of sheet carrying posts 6 each of which terminates in a conical head I which is adapted to be received in an aperture 8 suitably formed and positioned in the slat elements 4 or 5.. This structure causes the slats to be at a fixed distance from each other no matter how;, :many sheets are carried therein. The lower slat element 5 has attached'thereto near each of the ends thereof a locking post 9 which terminates in a locking neck I0 surmounted by a head II which is adapted to be received or extendthrough an; aperture I2 suitably formed and positioned on the upper slat 4. The upper slat 4 has pivotally mounted thereon the channeled locking lever I3 which has the locking slot I4 suitably formed and positioned to receive'therein the locking neck I0, for locking the two slat members together. The slat members 4 and 5 have further formed therein a plurality of spaced registering prong receiving apertures I5 which adapt the binder for being positioned upon the elements 25 of the prong unit 3. The covers I6 carried by the binder unit 2 have each formed thereinthe plurality of apertures I'I'suitably positioned to permit the posts Band 9 to extend therethrough' and to register with the apertures I5 as may benecessary when. the covers are properly positioned in the binder. 7 The leaves I8 carried by the binder unit 2 have formed and suitably positioned therein the apertures I9 which cooperate withthe post 6 or 6 and 9 to bind the sheets in place and which register 'with the apertures I5 or I! as may be necessary. For the purpose of uniformity I prefer to space my apertures 8, I2, I5, I1 and I9 and the posts 6 and 9 so that they are equidistant center to center. The sheet guide member 3 consists of a base ele-" mnt20 and the guide and positioning posts or arches 24. v

The base element 20 has positioned thereon along the front edge thereof the rail 2I which center.

has attached thereto the prong elements 25. The base element 26 has hingedly attached thereto along the rear edge thereof the rail 22 which carries the element 26 of each arch 24. The base element 26 has further attached thereto the resilient rear rail retaining elements 23. The base element 20 has further formed therein the apertures 29 through which may extend the screws 36 (see Figures 1 and 4) which serve to attach the member 3 to the table T.

It is to be noted that the prong elements 25 and 26 are so formed that together they combine to form the U-shaped arch member 24 which in the closed position (shown by the full lines in Figure 3 and the dot and dash lines in Figure 4) has two substantially straight sides connected by a curved element 28 and which in the open position (shown by the dot and dash lines in Figure 3 and the full lines in Figure 4) is composed of the element 26, having the straight portion 2'! and the curved portion 28, and the straight prong element 25. As clearly shown in Figure 4, the straight prong element 25 must be longer than the total Width or thickness of the binder 2 and its contents. The straight walls and curved connecting portion of the arch 24 serve to facilitate the movement of the cover 16 and the leaves l8 about the arches or guides 24 in the removal, shifting or the addition of leaves to the binder 2. For the sake of uniformity the prongs 24 have been so spaced as to be equidistant center to Although the manner of using my novel de vice is believed to be clear from the foregoing disclosure, yet to obviate any possibility of a misunderstanding the following detailed description is here given. Although it is not necessary to attach the sheet guide member 3 to the table T yet since by making such attachment the unit is made more stable we will-therefore assume that the sheet guide member 3 has been assembled and has been fastened down to a suitable table T by the screws 36 extending through the aper tures 29. Let us further assume that we start with the elements 25 and 26 of the arches 24 in the position shown by the full lines in Figure 3.

Let it be further assumed that we desire to replace several leaves carried by the binder 2. To add, remove, shift or replace leaves we proceed as follows:

The prong elements 26 are moved to open position (shown by the dot and dash lines in Figure 3 and the full lines in Figure 4). The binder 2 and the leaves which it carries are then placed upon the sheet guide member 3 to take the position shown by the full lines in Figure 4 so that the straight prong elements 25 extend through the registering apertures l5, l7 and 19. The locking levers H are then manipulated so as to unlock the slat 4. The slat 4 is then moved upwardly away from the ensemble as shown by the dot and dash lines in Figure 4. The prong elements 2B are then swung back to the'closed position shown by the dot and dash lines in Figure 4 and the full lines in Figure 3. When in this position the prong elements 25 and 25 combine to form a continuous guide element for the leaves which can now be moved to uncover the leaves at any point in the bound volume. When certain of the leaves have been shifted from the elements 25 to the elements 26 to uncover those desired,

such, for instance, as shown in Figure 1, the prong elements 26 are again swung outwardly to the open position and the new leaves 18 placed in position upon the posts 6 and the prong elements 25, or the old leaves are removed and replaced by new leaves or the leaves which are to be shifted are removed preparatory to shifting. After the sheets have been added or removed as may have been necessary the prong elements 26 are again swung back to the closed position (shown by the full lines in Figure 3 and the dot and dash lines in Figure 4) and the leaves !8 are swung back to the position shown in Figure 4. If it is desired to shift the leaves which have been removed to another position in the binder, the leaves remaining upon the guide means are shifted to the desired point where the insertion is to be made, the prong elements 26 are thrown to the open position and the leaves being shifted are inserted.) All of the above operations can be repeated any number'of times desired. When the above operations have been completed the prong elements 26 are then swung back to the open position and the slat 4 is replaced and locked in the position shown by the full lines in Figure 4. The binder and its contents are now removed from the guide member 3 for use wherever desired.

It is obvious that the method herein outlined may be used not only for the transferring and adding and removing of sheets wherever desired, but also for the assembling of sheets uponthe binder element 2. I

It is to be understood that the above disclosure is for the purpose of illustration only and not for the purpose of limitation since many changes may be made in the structure herein shown without departing from the spirit of my invention. It is for this reason that it is my desire that the claims which are hereunto appended for the purpose of defining my invention should be limited only by the prior art I claim:

1. A loose leaf binder consisting of a pair of slats each having a plural number of leaf binding posts positioned thereon and a plural num-' ber of apertures formed therein and positioned for receiving each of said binding posts, a locking post mounted on one of said slats and a locking lever positioned on theother of said slats for cooperative engagement with the said locking post for locking the said slats together, each of said slats having further formed therein one or more mounting apertures so positioned that the apertures of one slat register with the apertures of the other slat. V

2. A loose leaf binder consisting of a pairof slats each having a plurality of cone headed leaf binding posts attached thereto and a pluralityof apertures suitably formed and positioned therein.

for receiving the said cone shaped heads of the said binding posts, a locking post positioned on one of said slats near each of the ends thereof and a locking lever suitably positioned on the other of said slats near each of the ends thereof for cooperative engagement with each 'of said locking posts to lock the said slats together, each of thesaid slats having further formed therein a plural number of mounting apertures so posi- "tioned that the apertures'of one slat register with the apertures 01 the other slat.
