1 Claim. 1

This invention relates to improvements in a notebook, and has for one of its objects foldable inter-changeable and replaceable leaves, and a retaining strip to secure the leaves together, said leaves being in dual form, centrally folded with respect to their length.

Another object of this invention is to provide a, pair of-transparent flexible sheets to function as a cover'for the sides of the book as protecting means for the leaves and notationsplaced thereon while the notebook is being carried in the pocket, or otherwise.

A further object of this invention is to provide a simple and efiicient means, hereinafter described, to removably secure the leaves together for inter-changing theleaves to place the same between the transparent backs or covers of the book for immediatereference when such isrequired as the-notes are easily read through said transparent covers.

A still further object of this invention is to provide covers of agreater width than-the leaves contained therebetween so that said covers may be notched tonear the width of the leaves and in transverse relation with respect to their lengths at intervals therealongwherebythe notebook may be secured in a closed position by the application ofone ormore rubber bands seating in notches selectively without crimping the leaves along their edges, the'notches to function as an anchor against removal of the bands from the notebook when drawn from a pocket, or the like, or while carrying the book.

A still further object of this invention is to provide a notebook that will stand erect on the opening end as the same will automatically spread by tension of its leaves whereby notation lines transversely crossing the leaves are easily read when the book is so placed on a desk.

A still further object of this invention is to arrange apertures passing through adjacent both ends of the covers centrally thereof, whereby the. apertures at itsrockably connecting end-may be engagedby apin-like element driven .inthe wall and adapted to engage through the apertures of both covers, and furthermore by turning one of said covers to its open position the aperture in its other end may be engaged by the pin in like manner, while the disengaged cover in this instance will serve as a protection for the leaves from the wall.

A still further object of this invention is to rockably connect the leaves and covers by two or more endless or solid rings adapted to engage in apertures passing through the covers of the note- 2 book, the apertures'for the ring being in registry and severed fromtheir adjacent ends to communicate with the apertures tangentially to avoid a radialmovementof the rings from the apertures.

These and other objects will hereinafter be more fully explained, reference being had to the accompanying drawing forming a part of this specification, and in which like characters will apply to like parts in the different views.

Referring to the drawing:

Fig. :lis a side'view of the notebook.

Fig.2. is an edgeview of the notebook.

Fig. 3 is anenlargedendview of the notebook with respect ,toits binding end.

Fig. 4 is an open plan view of the notebook and being atthe center of its leaves to illustrate the position :of the strip for theleaves.

Fig. '5 is anopen plan' view of a dual leaf.

Fig. 6 is .an enlarged fragmentary edge view of the notebook adjacent its rookable connection and :being partially open to illustrate the position of .the retaining strip for the leaves.

Fig. '7 isa sideview of the retainer.

Asia more concise description of the invention, it'willbe'seen that the components consist of a plurality of elongated rectangular leaves I that are ruled transverselyin spaced relation as atA, said'leaves adapted to fold'transversely attheir longitudinal centers. Said leaves have elongated slots B in spaced relation transversely of the leaves and arranged to extend equal distance from each side of 'the bending point of the leaves when folded together, whereby as folded the said slots terminate into a U-shape for thepurpose later described.

It willbe'seen that the leavesaresimilar in contour and size and adaptedto stack inregistry at the time ofp1acingthe same between covers], that areformed from rectangular transparent flexible sheets of material, there being :a cover foreach side-of the notebook completion, said covers being greater in width than the leaves and likewise greater in length than the leaves when folded together. The width being increased as above stated is means to provide V-shaped notches C formed along the edges of the covers in spaced relation, the bottom of the notches terminating at or slightly outward from the edges of the leaves to receive a rubber band 3 seating therein; selectively, as shown in Fig. 1 as securing means for the notebook in a closed position, the rubber bands being a friction means to retain the notebook from sliding freely from a pocket, or the like, or lengthwise of the notebook while the V-shaped notches are means to avoid displacement of the band when frictionally engaged.

It will be seen that the covers are apertured as at D in registry with the outer slots of the leaves and being rockably connected by a solid ring 4 engaging in the apertures, whereby the covers are free to rock toward and from each other, it being understood that the rings are solid peripherally, and to enter the same into their respective apertures of the cover is through the provision of a slit E from the aperture outward through the end of the cover and being on a tangent with one side of the aperture with respect to its diameter as shown in Fig. 1. To enter the ring the cover adjacent the aperture or between the aperture and outer side of the slit may be bent to one side suificient for the wall of the ring to pass therethrough and into the aperture, while the bend portion is free to rebound to its normal position. The slit being so positioned as above stated is means to avoid direct registry with the ring when the book is being opened or tension imposed on the covers longitudinally from each other, and likewise to remove a cover from'the rings the same movement may be exercised to remove the ring.

To fill the notebook with leaves, attention is directed to Fig. 4 in which view the covers are opened and extending oppositely from the rings each way in alignment so that the outer slots of the leaves will pass freely over the rings until a desired number have been thus stacked together, and to retain the leaves it will be seen that a retaining strip 5 as shown in Fig. 7 will be engaged by the rings, the apertures F and slits G of which are similar to those formed in corresponding ends of the cover and applied to the rings in a similar way. When so engaged the edge of the strip adjacent the rings will engage the leaves thus stacked at their longitudinal centers extending transversely thereacross and being in length equal to the leaves. The notebook being thus assembled may be folded at the transverse center of the leaves and bound securely by the rings and the strip, while the other ends of the sheets when folded together are free to be opened leaf by leaf for the purpose of writing notations thereon which may occur in consecutive order and freely read through the covers.

Inasmuch as the covers are of greater length than'fthe leaves as shown in Fig. 2 is a means when the notebook is positioned vertically on its opening end, the covers will rock outward sulficient to brace the notebook thus positioned which is a convenience to read the notes at a greater range and without approaching the same as when laid flat on the desk.

As a memorandum, it will be seen that the covers are apertured at each end as at 6 and 6', re-

' spectively, being in registry with respect to their corresponding ends, and being centrally aligned on the longitudinal axis of the book. Being so arranged the notebook may be hung on a wall by aperture 6 when in a closed position, the back cover adjacent the wall being a protector for its respective leaves. Furthermore the covers may be opened one or both, selectively and hung on the wall by their apertures 6' if so desired, and the rings are means to permit wide opening of the covers as the same are separately carried thereby.

It will be understood that when the notebook is pendantedly carried at its rockably binding connection as above disclosed there is provided a center slot 1 as shown in Fig. 5, the bottom of which when the leaves are folded together is means to avoid obstruction of free passing of the hanging pin through the aperture of the covers, and such modifications may be made as lie within the scope of the appending claim.

Having fully described my invention what I claim as new and desire to secure by Letter Patent is:

In a notebook, a plurality of dual leaves of suitable length and width, the leaves to fold back on themselves with respect to their length, said leaves having a pair of slots, the slots being of suitable length to extend each way across the folding point of the leaves whereby U-shaped openings are provided when lapped back on themselves, each of said slots being adjacent its respective terminal width of the dual leaves, a pair of solid rings to engage in the slots, an apertured retaining strip, the length of which is equal to that of the width of the dual leaves, and the said strip being of suitable width and thickness and adapted to seat edgewise on the dual leaves at the folding point, the strip being slit from its seating edge to enter the apertures as means to insert the rings in the apertures of the retaining strip, whereby a plurality of dual leaves may be removably retained together as stacked, a pair of flexible transparent covers for their respective sides of the dual leaves when the latter is lapped back on themselves, the ends of said covers being apertured to register with their respective slots and means through which the solid rings are insertible to engage in the apertures, said retaining strip and covers co-acting to retain the dual leaves to engagement with the rings.
