UNITED STATES PATENT OFFICE CALENDAR MEMORANDUM PAD Harry J. Friedman, Forest Hills N. Y. 7 Application December 8, 1948, Serial No. 64,201

,This invention relates to calendar memorandum pads. More particularly, my invention pertains to calendar memorandum pads constituting a large number of bound pages which are adapted to be retained in an out-of-the-way position for future reference after passage of the dates borne on their faces. 7 p L Heretofore calendar memorandum pads of this type employed clumsy expedientsfor retaining pages which had been turned to lie against the back of the pads, and said turned-back pages gave rise to an awkward appearing ridge .at the binding.

.JItis an object of thepresent invention to provide an improved construction of calendar pad which permits the turned-back sheets to lie flat against the back of the pad andnot to add to the bulk of the pad at any point thereof.

It is another object of my invention to provide a calendar pad of the character described which is so constructed that no means need be employed to hold the outdated pages in their outof-the-way position.

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 construction hereinafter described and of which the scope of application will be indicated in the appended claim.

Referring now in detail to the drawings wherein I have shown one of the various possible embodiments of my invention,

Fig. 1 is a plan view of a calendar memorandum pad constructed in accordance with my invention;

Fig. 2 is a rear view of the pad on a slightly reduced scale;

Fig. 3 is a vertical sectional view through the pad, taken substantially along the line 3-3 of Fig. 1;

Fig. 4 is a horizontal sectional view through the pad taken substantially along the line 4-4 of Fig. 3; and

Fig. 5 is a front view of the backboard as it appears before mounting of the calendar memorandum pages thereon.

Referring now in detail to the drawings, the reference numeral denotes a calendar memorandum pad embodying my invention. Said pad comprises a backboard I2 of any suitable material such, for instance, as a strong, stifi cardboard or pasteboard. The backboard may be of, Vernj 1 Claim. (01. 40-119) cally elongated generally oblong shape with the top and bottom edges scalloped orotherwise pleasingly configured. The sides of the backboard may be reinforced with metal binding strips M having longitudinal portions rolled with the longitudinal edges of the board to form stiff lateral zones and thus enable the backboard better I to maintain its shape over a long period of use.

Near its top, the backboard has an elongated transverse extending slot 16 which, desirably, is of substantial width. Although as laterwillbe seen, the slot only need be wide enough to permit passage of one or a few pages at a time, in order to facilitate use of the pad, I prefer'to make the slot large enough to enable all of the pages to be slipped therethrough at once so that no matter how the pad may be handled, the pages cannot be jammed in the slot.

Overlying the backboard are a plurality of registered pages It). These pages are of the usual type found in calendar memorandum pads, that is to say, the same are comparatively thin and flexible and are so finished that their surfaces can be marked with pen or ink. Suitable information and lines are printed on the front surface of each page. For instance, this may consist of printing which divides each page into seven horizontal daily sections. Within each section several horizontal subdivisions may be provided in which the user can jot down memoranda. On the left-hand side of each section the names of the days of the week are imprinted together with the number of the day of the month. In addition, near the upper right-hand corner of each page there may be imprinted a tiny calendar IQ for the month.

Pursuant to my invention, the pad is joined to the backboard by an interconnected ring binder 20 which passes through the pad in the vicinity of the upper edges of the pages and through the backboard in the vicinity of the lower edge of the slot l6. By interconnected ring binder I refer to types of binders which consist of a plurality of parallel, concentric loops which are registered, spaced from one another along their common axis, and permanently interconnected. In general, their are two different kinds of binders of this type, only one of which has been shown herein. This binder 20 consists of a helical wire coil 22 having turns of uniform diameter. Each 360 turn is considered as one ring. The ends of the coil are turned inwardly to prevent the pages from slipping off the coil. The other kind of interconnected ring binder, not shown herein, comprices a plurali y. 91' Parallel K g 1 .1 9; .1191 are 3 connected to a common spine of strip running parallel to the common axis of the rings and being radially offset from said axis.

The pages and the backboard have formed therein series of perforations 24 to pass the rings of the binder.

The backboard may be provided with a metal grommet 26 near its top edge to facilitate hang ing thepad on a hook, nail, or like projection extending-from a wall. I

The backboard also is formed with slits 28 ex tending in a generally downward direction from adjacent each end of the lower edge of the slot [6. Due to this arrangement, when the pads are shipped and pressure is exerted on the edges of the backboard, the backboard will yieldrather than tear. V

When first used, all the pages of the pad are at the front of the backboard. As week after week passes, the corresponding pages are slipped through theslot t6 and permitted to fall against the rear face of the backboard. The used pages 30*will lie flat against the rear face of the backboard and will not bunch around the top binding as they-have heretofore. Thus, when first used, and at 'all subsequent times, the pad presents a neat, compact and attractive appearance.

It thus-will be seen that I have provided a device'whicha'chieves the several'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 m'i'ght'be made in the embodiment above set'for'th, it is to be understood that all matter 4 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:

A calendar memorandum pad comprising in combination a backboard constituting a single sheet of paperboard, a transversely extending slot in said sheet, a registered set, of pages on the front face 'of said sheet, the upper edges of said pages being disposed adjac'eht'th'e lower edge of said slot, said pages and the sheet in the region of the lower edge of the slot having registered series of "openings, and an interconnected ring binder, the rings of said binder passing through said series of" openings whereby by threading pages through-said slot they may be turned from REFERENCES CITED The following references are of record in the file of this patent:
