Cl; 281-45 This invention relates totpad-books. Said invention will be described hereinafter with reference to a calendar padtb'ook, that is to say, to abook in which the pad is imprinted w-ithsuitable calendar indicia; however, it is to be .understood that the-invention is not to be so limited except to the extent indicated in the appended'claims.

Heretofore pad books have been subject to various defects. For example, after the top page of a pad had been used or was-v out-of-date,- it was customary either to rip the page off, or to turn the page to overlie the rear surface of the back cover of'the book,whereby to expose-the next" succeeding fresh or current page. This either renderedthedetached page unavailable for'future reference, or made-the book' unsightly or unduly bulky after the pages hadbeenturnedbach.

It is an object of my invention to provide a pad book o'fZtli'e character described whicheliminates the foregoing drawbacks.

It is another object of my invention to provide a pad book of the character described which, although enabling used or out-of-date pages to be retained for future reference, so disposes these pages that they do not unduly encumber the book and, indeed, are no more noticeable or bulky in their out-of-the way position than in their ready-for-use position.

It is another object of my invention to provide a pad book of the character described which despite its increased advantages costs no more to manufacture than a conventional pad book.

It is another object of my invention to provide a pad book of the character described which has no more parts than an ordinary pad book, and is therefore of relatively simple construction.

It is another object of my invention to provide a pad book which is particularly neat and attractive in appearance, and, moreover, in which the hinge connection for the individual sheets of the pad is concealed when the book is closed so that the book does not appear to be too greatly different from an ordinary notebook.

Other objects of my invention in part will be obvious and in part will be pointed out hereinafter.

My invention accordingly consists in the features. of construction, combinations of elements, and arrangements of parts, which will be exemplified in the calendar pad book hereinafter described and of which the scope of application will be indicated in the appended claims.

In the accompanying drawings, in which is shown one of the various possible embodiments of my invention,

Fig. 1 is a front View of a closed calendar pad book constructed in accordance with my invention;

Fig. 2 is a similar view of the book as it appears when open;

Figs, 3 and 4 are enlarged fragmentary sectional views of the book, the same being taken substantially along the lines 3-3 and 4-4, respectively, of Fig. 2;

Fig. 5 is a perspective view of the open book during the process of turning back an out-of-date page; and

Fig. 6 is a fragmentary view similar to Fig. 2 but illustrating the back of the calendar pad: as an out-of-date page is about to be turnedon to the same.

Referring. now in detail to the drawings, the reference numeral 10 denotes a calendar padbook embodying my invention. Said book constitutes a front cover- 12 and a rear cover 14: Each of these covers includes a concealed stiffening panel. 16:made, for example, of heavy paperboard: The outer surface of eachpanel the'front surface of the-front stiffening panel and the rear surface of the rear stiffening panel) is covered'with an ornamental ply 18:of sheet material constituting, for example, a plastic-impregnated paper. This plyextends from the front stiffening panel to the rear stiffening panel, bridginga space between said panels so as to forma hinge section 20: that connects the front and rear covers. The internal surfaceof the ply is securedto the stiffening panels, as by an adhesive substance, e.g., glue, and the marginal edge'zones'of the ply are'turned around'the edges of'the stiffening panels to form clean edgesfor thefront and back: covers.

In a' conventional book of the character being described; the internal surfaces of the front and back stiffening'panelsa'recovered by one single sheet of'niateri-al;,e. g., paper, which extends fromone tothe other of'the: panels across the hinge section. This sheet is known as a fly inner sheet, and-likewise is pasted to the: two stiffening. panels.

However, in accordance with the present invention, I utilize a-different typeof fly sheet. More specifically, I- provide 1 a fly sheet 22 which covers Ofl the; front: and back stiffening panels" and which is" secured thereto, as by glue, being so disposed as to overlie the inturned edges of the front ornamental ply 18 whereby to conceal the same and provide a neat appearance. The fly sheet also includes a zone 24 which bridges the space between the two stiffening panels and aids in providing the desired hinge action.

Unlike a conventional fly sheet, the fly sheet 22 employed in a pad book embodying my invention is approximately four times the width of a stiffening panel, i.e., almost twice the width of an open book. This means that there is considerable extra material. As will be best seen in Fig. 3, this additional material is located at the middle of the fly sheet and is doubled at a distal fold 26 so as toform what in effect constitutes a tough strong two-ply sheet 28 that is hinged to the book, actually as a sheet thereof, at proximate folds 29 arranged adjacent the hinge section 20. Thereby the sheet 28 is free to swing between the front and back covers when the book is open. Moreover, due to its doubling, the sheet is strong enough, as soon will be seen, to act as a support for a pad.

Adjacent its upper edge, the doubled sheet 28 is provided with a linear row of perforations 30 adapted to be engaged by a helical binder 32 of conventional type consisting, as is usual, of a helix of flexible steel Wire.

I furthermore provide a pad 34 consisting of a stack of paper sheets of the same size arranged in registry. Adjacent its upper edge, said stack of sheets is formed with a linear set of perforations 36 which match the perforations 30, the helix 32 being threaded through the second set of perforations and thereby hingedly joining the stack of sheets 34 to the doubled support sheet 28, or, in other words, binding the pad to the sheet 28 at an edge of the latter.

The sheets of the pad can be blank if desired; however, in the form of my invention now being described, said sheets are suitably imprinted with indicia to convert the pad into a calender, e.g., a calendar in which each sheet includes the subdivision for the days of a week. Each sheet of the pad 34 preferably is subdivided in the usual manner to provide areas for the different days the inner surfaces" of the week so that the user can write memoranda or other suitable inscriptions thereon. Thus, even after the sheet is past-dated, the user still may Wish to refer to the same for one purpose or another.

After the sheet no longer is current, the user turns it around the helix 32, as indicated in Fig. 5, away from its front-of-the-stack position, until the sheet lies against the back of the doubled sheet 28 or overlies one or more sheets of the pad previously turned to this position. It Will be observed that the total thickness of the pad 34 and doubled sheet 28 never changes, so that when the book is closed, the space between the two covers remains the same, neither increasing nor decreasing as has heretofore been the case with calendar pad books.

The fly sheet 22 has a height somewhat less than the height of the front and back covers. However, in accordance with an ancillary feature of my invention, said sheet is not centered in a top-to-bottom direction with respect to the covers, but rather is offset in a downward direction whereby the helix 32 is located within the covers, i.e., it does not protrude above the same, when the book is closed.

It thus will be seen that I have provided a pad book which achieves the various objects of my invention and is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention and as various changes might be made in the embodiment above set forth, it is understood that all matter herein described or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A pad book comprising a front cover and a rear cover, each cover constituting a stiifening panel, a ply of sheet material covering the outer surfaces of both 4 said stiffening panels and bridging a space between said panels so as to form a hinge section that connects the front and rear covers, adhesive means securing the ply to the stiffening panels, a fly sheet covering the inner surfaces of both said stiffening panels, adhesive means securing said fly sheet to said stiffening panels, said fly sheet being approximately four times the width of each said stiffening panel, the side edges of said fly sheet being located substantially at the side edges of the stiffening panels, the central portion of said fly sheet being doubled at a distal fold to form a two ply sheet that is hinged to the book internally at proximate folds adjacent the aforesaid hinge section and internally of the pad book, said two ply sheet having a linear set of perforations adjacent its upper edge, a stack of paper sheets having a linear set of perforations adjacent its upper edge and registered with the perforations in the two ply sheet, and a helix threaded through all said perforations to hingedly join the stack of paper sheets to the two ply sheet.

2. A pad book as set forth in claim 1 wherein the fly sheet is offset downwardly from the top edges of the stiffening panels to locate the helix within the confines of the covers.
