IN V EN TUR. (bo/Ez J//WES BY United States Patent O LOOSE LEAF BINDER James cooper, Solvay, N.Y., assigner to Hally & Mcchesney, Inc., Syracuse, N.Y., a corporation of New York Application March 1, 1957, Serial No. 643,340

Claims. (Cl. 129-23) The invention has as a further objectv a binder of the type referred toV embodying av new structural arrangement whereby the binder has maximum paper capacity for, or in relation to, the over-all thickness of the binder.

A further object resides in the binder having a minimum width in relation to the width of the sheets, the arrangement being such that no parts of the binder extend beyond the edges of the sheets and no operating parts of the bin-der extend beyond the width of the sheets.

The invention has as a further object a structural arrangement for the back member including parts so constructed that they may be assembled to vary the thickness of the binder to accommodate a greater or less number, or amount, of sheets.

The invention has as a further object a loose leaf binder wherein the leaf impaling posts are iixedly secured intermediate their ends to the back member, whereby leaves may be removed, or inserted, from one side of the binder without disturbing the leaf bin-ding at the opposite side of the binder. This arrangement permits the manufacture of the essential parts making up the back member structure in volume and yet provides for the production of binders having varying leaf capacities.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

In the drawings:

Figure 1 is a side end view of the binder shown with leaves or pages mounted therein.

Figure 2 is a portion of the binder of Figure l opened on one side thereof.

Figure 3 is a section taken on line 3-3 of Figure 2.

Figure 4 is an element of the loose leaf binder.

Figure 5 is another element of the loose leaf binder.

Figure 6 is a section taken along line 6 6 of Figure 3, with parts removed.

Figure 7 is an end portion of a section taken along line 7-7 of Figure 3.

The back member of the binder, indicated generally at B, includes a pair of complemental channel members 1 superimposed on each other with the intermediate walls of the members lying in a common plane, see Figure 3. The outer leg 2 of the channel members are formed along their free edges with a plurality of spaced apart. hinge eyes 3. The inner legs 4 are apertured to receive fastening members, as bolts 5.

A sheet post supporting bar 6 is positioned between the legs 4 of the channel members and it also is apertured to receive the bolts 5. A plurality of sheet impaling ICC posts 7 are xedly secured intermediate their ends to the bar 6. The posts are spaced along the bar, see Figure 2, and are spaced outwardly from the channel members, See' Figure 3. The bar 6 is formed with apertures 8 for the reception of sheet impaling pins hereinafter referred to.

A keeper bar 9 is mounted on the inner surface of the legs 2 of each channel member and is formed with ears 10 extending outwardly through slots 11 formed in the channel members. The bars 9 are formed with cam slots 12 extending in angular relation to the 'axisy of the bars, see Figure 4. Shouldered rivets 13 are fixed tothe legs 2 of the channel members and extend into the slots 12 and serve to mount the bars 9 for sliding movement relative to the channel members.

By' reference to Figure 2, it will be apparent that upon lengthwise movement ofthe bars 9 in one direction, as upwardly in Figure 2, the bars will be moved inwardly away from the posts 7, moving the ears 10 into the channel members 1, this being brought about by the angular cam slots 12. Movement of the bars in the opposite direction effects movement of the ears outwardly toward the posts 7, in .whichA position they overhang the sheets impaledr on the posts. v l i The binder has a back piece shown in Figure 5'. This back piece is rectangular in general form complemental to the sheet holding structure, consisting of the channel members, the bar 6 and posts 7. The back piece has end portions 18 formed with upstanding flanges 19 which loverlie and close the ends of the channel members, see Figure 1. The anges 19 are formed with apertures 20 arranged in registration with the ears 14 on the keeper bars. A pencil, or the like, may be inserted through the apertures 20 to conveniently actuate the keeper bars into and out Aof leaf retaining position. The end portions 18 of the back piece are connected by sides 21 formed with spaced apart hinge eyes 22 arranged for registration with the hinge eyes 3 formed on the channel members 1. The opening, defined by the end portions 18 and the sides 21, is closed by a anged plate, to the outer surface of which is aiiixed a covering of buckram, or leather, 23 on which any desired indicia may be printed. This plate is retained in the back piece by the end flanges 23a offset to overlie the end portions 18, see Figure 7. The inner edges of the ilanges 23a engage a spacer block 24 positioned against the legs 4 of the channel members, see Figure 3.

The binder is completed by a pair of cover members 25 formed with hinge eyes 26 which, together with the hinge eyes 3 on the channel members and the hinge eyes 22 on the back piece, receive pintle rods 28.

Preferably, a pair of leaf retaining bars 30 are positioned on the posts 7 for sliding engagement therewith. The bars 30 have pins 31 extending through perforations in the sheets and through the apertures 8 in the post supporting bar 6.

The thickness or sheet capacity of the binder can be readily increased by the use of spacers 35 between the legs 4 of the channel members, in which case posts 7 of complemental length are used as well as a back piece of complemental width.

It will be apparent that the sheet holding structure of my binder embodies a minimum number of parts and that the leaf or sheet impaling posts are rigidly fixed to the back member intermediate their ends, permitting for convenient removal and insertion of sheets when the binder is opened, and not requiring any special manipulation of the back member to effect retention of the sheets on the posts, as is the case in loose leaf binders now in used. It will be observed that my binder has maximum paper capacity for the overall thickness of the binder, and that the binder is of minimum width in relation to the width of the sheets and, by reference to Figure 6, it will be apparent that the binder does not have any operating parts extending beyond the width of the sheets, or movable outwardly therefrom, to position the binder for insertion, or removal, of sheets.

What I claim is: r

1. A loose leaf binder comprising a back member including a pair of rearwardly opening channel members having parallel inner and outer legs, said inner legs being aixed together with the intermediate walls of said channel members lying in a common plane, a pair of covers hinged to the rearward edge of the outer leg of each of said channel members, a plurality of leaf impaling posts xedly secured intermediate their ends to a supporting bar carried by and extending forwardly from the intermediate walls of said back member, said posts being spaced apart along said back member and being spaced outwardly therefrom, and means cooperable to retain leaves, or sheets, on said posts.

2. A loose leaf binder as defined in claim 1, wherein said supporting bar is xedly secured between the inner legs of said channel members, said plurality of leaf impaling posts being fixedly secured intermediate their ends to said post supporting bar, said posts being spaced along said bar and extending transversely to the bar and in outwardly spaced relation to the back member of the binder.

3. A loose leaf binder as defined in claim 1, wherein said binder further comprises a pair of leaf retaining bars formed with post receiving apertures for sliding movement on said posts toward and from said post supporting bar to retain a plurality of pages or leaves which are impaled on said posts, and means carried by the back portion to restrain said leaf retaining bars against removal from said posts.

4. A loose-leaf binder as defined in claim 1, wherein said last-mentioned means includes a keeper bar mounted in each side edge of the back portion and having an ear extending toward said posts, said keeper bar being movable relative to the back portion to move said ear into and out of position overlying the leaves impaled on said posts.

5. A loose leaf binder as defined in claim 4, wherein the means to retain leaves or pages on said posts further includes a leaf retaining bar formed with post receiving apertures for sliding registration with said posts, said leaf retaining bar being retained in the binder in said sliding registration by said ear on said keeper bar.
