6 Claims.

This invention relates generally to binders for pamphlets, magazines, books, booklets or other bound'forms and the like and more particularly to binders of the type known as temporary binders used to hold inserts and other bound forms of different kinds, any of which may be removed or replaced from time to time, as desired, or as may be necessary to keep the contents of the binder'up to date. V

The object and general nature of this invention is the provision of a temporary binder arranged to have theappearance of a regular sewed and bound book but which is provided with suitable insert-engaging .means whereby the pamphlets, booklets, and the like can be inserted and held securely in place so that it is impossible for them to fall out, without the moving, adjusting or installation of wires or rods or the like, other than the closing of a hinged plate, and without requiring that the books, pamphlets or the like be punched, out or otherwise mutilated in any way.

Another important feature of this invention is the provision of a temporary binder having capacityto. hold a considerablenumberv of inserts or books or a relatively large volume, such as state statutes and the like but so' constructed and arranged that the insertion of the books or pamphlets, can be easily accomplished and the insert or inserts'will be securely held in place. A further feature: of thisinvention is the provision of a hinderwhich is easy to open for changing the inserts and easy to close after the change has been made.

A further feature of this invention is the provision of pronged means carried by the back or backbone of the book which is so constructed and arranged that while a plurality of prongs is provided, the prongs are staggered, that is, alternate ones are shorter than the others or some similar arrangement, so that the insertion of the pamphlet, bo'okor booklets is appreciably facilitated since .all of the prongs do not enter the insert at the same time. Another feature of this invention is the provision of improved supporting plates, one of which is fixed to the back of the binder and the other of which is hinged thereto, carrying the prongs and so formed that the prongs are held rigidlyand firmly in position with no tendency to twist out of position at any time. It is a furtherfeature of this invention, which is of particular importance ina binder of considerable size, is the provision .of .means .securing a tight,.firm hinge between the'sides of the binder and theback thereof whereby an extremely strong and durable hinge is provided forv the binder and which adequately resists the stresses imposed on the hinges by the relatively heavy weight of the inserts carried by the binder.

These and other objects and advantages of this invention will be apparent to those skilled in the art after a consideration of the foliowing detailed description taken in conjunction with the accomrigid back with the spring latch secured theretobut before the other parts of the binder have been attached;

Figures 4 and 5 are perspective views of the rigid and hinged prong plates, respectively;

Figure 6 is a section taken along the line 66 of Figure 2;

Figure '7 is a somewhat diagrammatic view showingthe manner of'placing an insert in posi-' tion on the prongs of the fixed plate;

Figure 8 is a view similar to Figure '7 but illustrating the action of the hinged plate inswinging the same into position to hold the insert in the binder.

Referring now to the drawings, more particularly to Figures 1 and 2, thebinder or cover in which the principles of the present invention have been embodied is indicated inits entirety by the reference numeral I and the insertor inserts which the cover I is adapted to receive is indicated in its entirety by the reference numeral 2. As shown, the insert 2 is in the form of a relatively voluminous book that might, for example be of a volume of state statutes, a legal directory or the like. Heretofore, statute books, legal directories and the like have been published periodically, usu ally every year or two, and provided with the ordinary fixed' binding. This construction is, however, relatively expensive, considering the fact that every year or two the entire volume has to be replaced. According to the present invention, we

I time. 7

, It is to be understood, however, that the presinserts of relatively small thickness which may or may not be bound as described above.

One particular construction which the present invention contemplates is the provision of a temporary binder for a number of inserts with insert receiving means especially adapted to accommor date thin supplementary inserts which may be removed and replaced from time to time intermediate the periods for removal and replacement of one or more of the inserts. Thus, the statute book, legal directory or whatever subject matter is included in the inserts may be kept up to date by removing and replacing the supplements orone or more of the inserts without requiring the.re-. moval and replacement of an entire volume. der certain conditions, of course, as first mentioned above, it may be desirable to provide only a single but relatively thick insert depending, of course, on the subject matter.

The temporary binder 3 consists of a rigidback 6 and relatively heavy covers 7 and 8 hingedly connected to the sides of the back or backbone 5. As-best shown in Figure 2, the back 6 consists of a relatively thick block H, usually of wood but not necessarily so, and each ofthe covers 3 and '23 includes a relatively heavy board 12 having abevelecl edge l3. The back H and the boards I? are covered with any suitable material, such as binding fabric, leather or the like, which is indicated by the reference numeral l5. Preferably, moreover, the material I5 is relatively strong artificial narrow sides 24 and Zia-being disposed adjacent the beveled edges I3 of the cover boards l2,

" To provide a reenforced hinge between each of the covers and. the rigid backwe provide a strip of canvas or other suitable material indicated at 2i, and glue the same, as at 21a, to the itto the flat inner side thereof.

the other side of the rigid back 9| is made in the r bevel i3 of the adjacent cover and extend the same across the edge of the backbone and glue The hinge at same way. Then across both hinges and the inner face 2| of the back l we provide a relatively heavy reenforcing cloth 29 and glue the. same to the inside margin of each of the cover boards 12, to the adjacent portions of the hinge strip 2? and to the inner flat side 2| of the rigid backbone ii. The binding is then completed by in side pieces 3| whichare glued to the inside of each of the cover boards I2, and each extending from the flap I7 and over the reenforcing cloth 29' to a point inside of the hinge between the cover and the back.

When the binder is constructed in this manner,

there is a tight, firm hinge between the sides or cover of the binder and the back or backbone,

. and the hinge is extremely strong and durable andv is more than adequate to accommodate the bone II is formed with notches 35 and 36 at the ends of the rigid back, the notches or slots 35 and 36 extending generally longitudinally inwardly and in a plane parallel to the plane of the inner surface 2|. An insert receiving prong plate, indicated in, its entirety by the reference numeral 4| and-best shown in Figures 2 and i, includes a plate member 42 having an edge 43 that is curved tocorrespond to the curvature of the rigid back 6 (Figure 6). A tongue it has a flange 45 that is secured in any suitable manner 'to the plate 42, as by spot welding 36.

. The plate 42 at its upper or inner edge is pro- "vided with a bent-over margin 48 which is slotted at .49. This section of the plate 42 carries a plurality of prongs 5|, and as best shown in Fig- "Qure i, the prongs 5| are arranged in pairs, being formed as a part of a U-shaped strip indicated in'its entirety by the reference numeral 53. The

intermediate portion 5iof each U-shaped strip is of the same dimension as the distance between adjacent slots 49, whereby the tongues 5| can be inserted through the slots 49 in the plate 42. For purposes'of clarity, the nearest prong member 53 is omitted in Figure 4 and portions or the turned-over part 58 of thestrip 62 adjacent the next memberiii are broken away. Certain of the other prongs have also been omitted in order tov show the. member 43. It, will be seen that after the members 53 have been inserted through the slots 49 and the flange or margin bent'over into the position shown in Figure 4, all of the prongs 5| are held rigidly and firmly in position against displacement in any direction, and particularly against being twisted out of position, as

might occur if the prongs 5| were individually mounted as separate pinsr As bestindicated in Figure 2, after the tongue 53 of the prong carrying plate member 4| is inserted in place in'the slot 35, a rivet 56 is driven through the tongue t3 and the back H to hold the parts rigidlyand permanently together. Preferably, the back II and the plate 43 are provided with openings to receive the rivet 56..

The member 4| described above carries-the prongs 5| in fixed and rigid relation with respect to the rigid back 6 of-the binder. At the other end of the back 6 a second similar set of prongs are carried, but these prongs are hingedly mounted and provided with suitable latch mechanism for releasably holding the prongs in insert holding from .theinsert to permit the removal of the latter. r

Referring nowmore particularly to Figures 2, v

3 and :5, the reference numeral 6| indicates the hinged prong plate member which includes a plate 62 substantially identical with the. plate 42 described above. The plate'62 also has a bentover setcion 63. which is slotted at 64 to receive prong members 65. The latter are similar to or identical with the prong members 53,"described above, and are likewise provided with prongs 66 which are. rounded and pointed at their inner ends, this being to facilitate the entrance of the prongs in between, the leaves of the insertjto be secured in the binder.

It will be noted from .both Figures4 and 5, that certain of: the prongs are shorter. In the-preferred form one prong of each pairis shorter than.

the other prongs, as shown in Figure 4', but ohviously one member, 52 or.65,-could have'prongs shorter or longerth'an'the prongs of the adjacent member. This construction embodying prongs-of different length, whether; alternately short and long, or anyv other arrangement,-has the advane; 1g

tage that it is easier to insert the prongs into an-insert where'some of the prongs are started in between the leaves before the others are started. This is especially true Wherethere are a con-' siderable; number of prongs, as illustrated, and where la relatively large amount of metal is to be inserted into the insert adjacent its back, the staggered effect of the prongs permits onehalf of the prongs to enter first and theshorter prongs to enter later. This construction'is of especial importance in connection'with the hinged prong plate 8 I as will'be explained below. The mounting of the prongs 66 in the plate 62 is substantially the same as that described above in connection is not believed to be necessary.-

The hinge, best shown in Figure-5, by which the plate 62 is fastened to the backbone II is indicated in its entirety'by the reference numeral 16 and consistsof a long leaf or tongue H and a short leaf 12 fixed tothe plate 62 in any suitable manner, as by spot welding; The pintle connecting the leaves H and 12 is indicated at 15. The leaf 1| is apertured, as at 16, to receive.

. open to the position shown in dotted lines in Figures 2 and 8.

'The member 6| is releasably latched in closed position (Figure 2) bymeans of a flat spring 83 which is disposed in a notch or slot 84 formed in the block and a registering notch 84a in the die cutplate 80. The inner end of the spring 83 isrigidly secured in the inner end of the slot 84 by fasteners 85, and the outer end of the spring 83 is formedwith a nose 81 which has a flange 88 of reversely bent formation. The nose 8'! is adapted t'denter a notch 9| cut in the plate '62,

and when the prong plate member 6| is closed,

the'nose 8'! of the 1atch83 is adapted to engage overthe inner edge of the opening 9| and securely-locks the hinged plate'member 6| in closed position, as Shown in'Flgure 2. The latch may be releasedmerely by pressing on the flange 88 and'springing the member 83 toward the center of the opening 9|. The inner edge 9|a. (Figure 2) cf the opening 9| is'beveled and cooperates with theflange' 88 to facilitate the locking of the prong plate 6| in closed position.

The operation of our improved binder is substantially as follows:

When it is desired to place an insert in the binder, the latter is supported with the back flat and with the covers and 8 or at least one of them, held upright so as to serve as sides to receive the insert, somewhat as indicated in Figure '7. Then with the insert 2 held by one hand and the binder with the other the insert is slid to the right (Figure 7) along the backbone 6 so as to force all of the rigid prongs 5| in position bound volume, but is of course not necessary, and where the insert 2'is in the form of a number of booklets and the like, insertible singly, the prongs 5| may be of the same length. After the insert 2 is forced over the prongs 5| and substantially up against the plate 42, as shown in Figure 8, the hinged prong plate member 6| is then swung about its'hing'e axis 15 to cause the prongs 66 to enter between the leaves of the insert 2 at the top of the latter. It will be noted that whether the insert 2 be a single volume or a plurality of pamphlets orthe like, all the prongs are'inserted when the hinged plate 6| is closed. Hence, in this case the staggered prong arrangement mentioned above is quite desirable. Further, from Figure 8 it will be noted, not only that the longer prongs 66 begin to enter first,-but that both sets of long and short prongs begin to enter between the leaves of the insert 2 at points, indicated in Figure 8 by the reference character x, which are I farther away from the back of the insertthan are the prongs when the hingedplate is finally swung into its locked position (Figure 2). During the time that the prongs 66 are being forced into the insert 2, it will be noted that the flange 88 of the latch 63 engages the inner wall of the opening 3| and as the'plate is swung inwardly rides over the wall edge 9|a sothat when the plate member 6| is fully closed against the insert the spring 63 snaps the nose 8? over the inner edge of the opening 9|, thereby automatically locking the hinged prong plate member 6| in closed or locked position.

- The number of prongs 5| and 66 may vary as desired. If only single volumes are to be accommodated, as few as four or less prongs may be su-fiicient, but where the binder is to receive a number of pamphlets, supplements and the like, there should be at least as many prongs'at each end as there are booklets to be accommodated.

It will be noted that reference was made to the fact that the bottom of the insert is placed'ag'ainst the fixed prong plate member 4|. This is not essential, of course, but is desirableinasmuch' as when the book is placed in upright position on a. shelf or the like, the'weight-of the leaves is borne by the fixed prong'plate member 4|,-.as shown in Figure 1. If the insert 2 were placed in the binder in the opposite relation, the weight of the insert would be sustained principally by the spring latch 83. As shown,=however, where the weight of the insert is borne by the fixed prong plate member It will thus be noted that the hinged connection between the covers 1 and 8 and the back 6 of the binder is sufficiently strong to accommodate all stresses imposedthereon by virtue of the weight of the insert.

It is an easy matter to remove any or all of the inserts, as desired. All that it is necessary to do is to spring the latch 83, and swing the hinged prong carrying plate 6| outwardly. Then the desired insert .or inserts may be removed and replaced by others. that it is only slightly more difiicult to remove and replace the insert where the latter constitutes the entire book 2 than is the case where there are a number of inserts and they are removed and replaced one at a time. As shown in Figures 4.- and 5, certain of the prongs are closer together than others. The particular advantage of this arrangement is that the binder of our invention ac- In this case it may be noted commodates relatively thininserts, whicnmay'be in-the form of supplements to the main insert 0 1.:
