invention relates to new and useful improvements in a loose-leaf record book.

More specifically, the invention proposes the construction of a loose-leaf record hook having 5 a plurolity of leaves each consisting of a. pair oi superposed sheets secured together along their edges and formed with a plurality of superimposed openings orransed in spaced horizontol end verticol lines for receiving extension portions it formed. on one side of a. card adopted to he mounted upon said. leof.

Heretoiore rlevlces of this type were constructed by attaching notched strips along the length of a sheet at spaced positions with relation to each 1 otherencl provided with o plurality of cords having notched portions eneogeahle with the notches food in sold strips for holding the cards in position upon the sheet.

Still further it is proposed to form the openings or o trioneulor shape with a right angle at the junction oi the altitude and the base with the hthennsee of each vertical row ofopenings directed away from each other in a manner to pert the extension portions to be easily en= paged therethrough and provide a. four point looking arrangement to prevent relative movement between the carol and sheet.

A further object of this invention is to form the openings in at substantially flat sheet in such $9 a manner that the card superimposed thereon will at all times remain in substantially flat position with relotion to the sheet to prevent the some from bending inwards at the center and provide a smooth surfoce to make it easy to write $5 upon the cords.

Still further it is proposed to tension wrtion on one side of the card in such a manner that it will he capable of acting as o hinge to permit the card to be easily swung bachtfiwards without hecomin'edeteched from the leaf to expose the cords located therebeneeth.

r further comprehension of the. invention, and oi? the objects end advantages thereof, referenoe will he had to the following description to and accompanying crowing, end to the appended 88 plated leaves. per se.

form the em Fig. 4 is t view similar to Fig. 3 illustrating one of the steps in the manufacture of the leaf.

Fig. 5 is a. sectional view taken on the line 5-5 of Fig. 4.

6 is e, sectional view on the line 6-8 of 5 g. raging 7 is a sectionol view on the line li of Fig. o is e. perspectiveview of one of the cards per co. m

The loose-loot record book, according to-thls invention, comprisesa loose-leaf cover it having e. plurality of pairs of rings H upon which a pliity of leoves ere adopted to be mounted in such to manner that each of the leaves may he turned for exposing the cards i2 mounted thereon. Each of the leaves is constructed in an identical merend comprises a. pair oi.

superimposed sheets it secured together along their outer edges. A binding strip It is engaged co over three edge portions oi the sheets 63 and is held in position by stitches l5 engaging therethrough to hold the superimposed sheets together asa t. The sheets to are formed with a pluraiity of superimposed openings it arranged in no spaced vertical lines along the length of the sheets to. A sheet ot'specer material ii is insorted hetween the adjacent faces of the sheets it through the open edge portions thereof for keeping the rows of openings it formed in one so of the sheets spaced irons the openings it formed in the other of the sheets. A second binding strip it lsengaged over the fourth edge portion of the sheets 88 for completely encaslng the spacer materiel ll.

The openings it are triangular in shape with their right angles loccted at the junction of the altitude and the hose. The hypothenuses of the triangles in each row oi openings are directed away from eocn other, as clearly shown in Figs. co 3 end 4. openings it in the sheets it are arranged in pairs with respect to horizontal points along the vertical lines in which they are also positioned.

A cord 62 for esch of the horizontal pairs of co openings to has an extension portion 62 formed on one side. thereof. The ends of the extension portion 82* are formed with outwardly directed elements 52 which are adapted to be engaged V with each horizontal pair of openings for mainso taming the cards in position on the leaves. The outwardly directed elements are easily engaged with relation to each horizontal pair of openings by first slipping one of the outwardly directed elements i2" beneath the hypothenuse 01' one 01 the 65 openings and then slightly bending the card to contract the end portions ii" to permit the other end portion i2" to be slipped beneath the hypothenuse of the opposite opening l6 the other vertical row.

Each of the cards i2 is formed with a. line of perforations 18 extending along the width thereof and located between the extension portion i2 and the card proper for permitting thev card to be folded backwards along this line to permit the extension portion l2 to act as a hinge and remain in position with relation to the leaf to permit any number of cards to be folded rearwards to expose the face of any one card mounted upon the leaf.

The construction of the outwardly directed ele-.

ments I2 is of a width substantially equal to the altitude of the openings 16 so that the top of the extensions l2 will bear against the'junction between the altitude and hypothenuse of the openings Hi to form a pair of lock points on each side of said card. While the top edge is engaging against the said junction the bottom of the extensions will engage against the junction between the base and the hypothenuse of each of the openings to form a bottom pair of lock points on each side of said card. Thus each card has four lock points as clearly shown in Fig. 2, two lock points being located on each side of said extension portion for preventing any relative movement either .vertically or horizontally between the cards l2 and the leaves on which they are mounted.

One'of the side edge portions oi. each of the leaves, namely the one having the binding strip I4, is formed with a plurality of openings l9 which are adapted to be engaged by the pairs of ited to this specific construction as it is also possible to construct these sheets from relatively stiff cardboard or other similar material.

A rib 20 is embossed between the adjacent openings l6, as shown in Figs. 6 and 'l, for stiflening thematerial'located between the openings to prevent the-leaf from collapflng under weights placed on the edges thereof. These ribs 20 are embossed in the sheets after the leaves have been completed.

While we have illustrated and described the preferred embodiments of our invention, it is to be understood that we do not limit ourselves to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described our invention, what we claim as new, and desire to secure by United States Letters Patent is:

1. Ina loose-leaf record book, a leaf, comprising a pair of superimposed sheets secured together along their edges and formed with a plurality of superimposed openings arranged in vertical lines spaced from each other, a sheet between said sheets for separating said openings, said openings being formed in said sheets in pairs with respect to horizontal points along said vertical lines, a card for each of said pairs of openings and each card having at one side an extension formed with outwardly directed end elements engaging into the openings of one horizontal pair of openings for holding said card in position on said leaf, and ribs embossed in said leaf between reenforcing said leaf.

2. In a loose-leaf record book, a leaf, comprising,

a pair of superimposed sheets secured together along their edges and formed with a plurality of superimposed openings arranged in vertical lines,

spaced from each other, asheet between said sheets for separating said openings, said openings being formed in said sheets in pairs with respect card for each of said pairs of openings and each card having at one side an extension formed with outwardly directed end elements engaging into the openings of one horizontal pair of openings for holding said card in position on said leaf, and ribs embossedin said leaf between the openings of each vertical row of openings for reenforcing said leaf, said ribs formed in one of said superimposed sheets being concaved and resting against the sheet inserted between said sheets for raising the edges of said openings for facilitating the engagement of said end elements into said openings.
