C. D. BROWN LOOSE LEAF BOOKLET I 1 11-? Filed May 14, 1924 INVENTOR M LFTTORNEY Patented Mar. 17, 1925.

UNITED STATES CLARJllhl'fiE DOUGLAS BROWN, OF IBAY SIDE, NEW YORK.

LOOSE-LEAF BOOKLET.

Application filed May 14,

T 0 all whom it may concern Be it known that I, CLARENCE DOUGLAS BROWN, a citizen of the United States, residing at Bay Side, Long Island, in the county of Queens and State of New York, have invented certain new and useful Improvements in Loose-Leaf Booklets, of which the following is a specification.

This invention relates to booklets adapted for general use and especially for widespread commercial circularization, and more particularly to booklets having standardized covers and interchangeable fillers that vary in subject matter adapted for ready assemblage and engagement within said covers. V

An object of this invention is to provide a booklet cover which may be made up in large quantities to be kept in stock and used as desired as a carrier of one or more issues or editions of fillers, the cover being so con structed as to render it suitable and convenient to receive the successive editions of fillers from time to time.

Another object of this invention is to provide a filler composed of leaves which in any issue or edition are usually uniformly alike as to size and form, said filler being adapted to be received and held by one of the aforesaid covers, whereby when it is desired to make up a number of booklets for purposes of circularization or the like, the filler having a predetermined printed content is rapidly and cheaply engaged within the covers,

the booklet being thus complete.

Another object of this invention is to provide a booklet having engaging means for the filler comprising an eyelet'orthe like whereby the booklet may be suspended by a hanger threaded through the eyelet.

lVith the foregoing and other objects in view the invention consists in the arrange- 1924. Serial No. "713,117.

open cover and one method of inserting a gle sheet or strip of paper or the like bent or folded upon itself along a line 11, the portions of thecover adjacent to such line forming a back along which either or both of the cover pages or sides may be hinged at 12. The cover is made of any suitable material or quality according to the intended k purpose but which preferably is fairly flexible and yet thick enough to possess a certain amount of stiffness. The cover can now be said to, consist of two main portions, the back 13 which is substantially of flat U-form comprising that part of the cover adjacent to the folding line and between the hinge lines 12 and the sides or cover pages 14- extending from the hinge lines-to the free edges of the cover.

In the practice of this invention the cover is provided at the ends of the back and between the foldingline 11 andithe hinge line 12 with some suitable holding or locking means whichhas the function of forming within the back a pocket 15 adapted to receive and hold, more or less permanently, the filler leaves of the booklet. Said pocket is preferably so constructed that it has an undercut or end extension 16 leading toward each extreme rear point or corner of the back for a purpose soon to appear. Said holding or locking means may assume various forms, but for the sake of simplicity and cheapness of construction, I have indicated the same in the form of hollow rivets or eyelets 17 and 17 driven directlythrougli the end portions of the pocket and not far to the rear of the hinge line, thus providing between the rivets a pocket with a neck having a constant perimeter. In forming the pocket, the eyelets grip the adjacent side portions of the cover back against each other, no washer or collar about the eyelet being ordinarily necessary 'or'desirable between the contacting portions aforesaid for the sake of simplicity and cheapness in construction. A hanger or string 18 may now be threaded through the eyelet 17 if desired to permit the assembled booklet to be suspended from a nail or the like.

The cover may of course have any suitnection with the circularization or' other work for which the booklets are intended to be printed, pressed, or otherwise indicated therein.

The leaf 19 is of suitable size and form adapted to be received within the cover. All the leaves will be of the same construction and may thus be used interchangeably with any standard cover. The printed matter thereon, however, will vary from" time to time to suit the users varying business requirements. j

As shown in Fig. 3 the leaf 19 has a hinge line 20 formed adjacent to a side edge there of and parallel to said edge. Notches 21 are cut or otherwise formed at the upper and lower corners of the leaf along the side aforesaid. The notches are preferably of V- form, forming acute angles or points 21, and the adjacent edges of the Vs are inclined toward each other thereby forming a dovetail locking tongue which 1s of a sizegreater than the neck of the pocket 22. This tongue is adapted to enter the: pocket 15 and with said points engaging behind the eyelets 17 and 17 to retain the leaf within the cover. The notches 21 are so formed that they are 'ada-ptedfor easy and rapid reception of the eyelets, and consequently the locking tongue can be inserteid into' the pocket 15 with ease and rapidity.

To insert a li'ller, wh1ch may comprise one r more leaves, into the cover, the cover is opened somewhat as shown in Fig. 2, and one end portion or point 21 of the tongue is projected directly into its seat 16 by a motion such as that indicated by the arrow (0. The filler is then flexed or buckled by forcing it in the direction indicated by the arrow Z) against the eyelet 17 whereby the effective length of the tongue is decreased so that the other point thereof can be inserted into its pocket or seat 16 to engage behind the eyelet 17 as indicated by the. arrow at c. The flexibility of the cover allows for suflicient spreading of the pocket to permit the flexing and inserting action aforesaid through the neck of constant perimeter,

and when so inserted the filler will lie in straight or fiat position and the cover may then be closed. The normal tendency of the back 13 will be to retain the filler in such flat position and consequently the locking tongues in engagement with said eyelets. The booklet is now completely assembled.

A. modification of my leaf is shown at 19 in Fig. at. with an edge substantially at right angles to the backed-ge of the leaf, thereby eliminating the necessity for flexing the leaf or buckling it to insert the same 1nto the cover. Thus after engaging the upper point 21 of The lower notch 28 is formed the tongue 22 behind the eyelet 17, as shown by the arrow (4, the leaf is rotated clockwise about this eyelet until the tongue 22 has passed the eyelet 17 and entered the pocket 15, the direction of insertion being then indicatedby the arrow Z). The. lower portion of the tongue thus abuts against the eyelet and prevents a downward movement of the filler and the consequent disengagement of the upper portion of the locking tongue. Hence in both forms shown the filler will be self retained inthe cover by virtue of the dovetail point 21 interlocking back of the holding means 17, and so the wa -1a of the liller will not cause the "same to slipfi'onithe cover even though the structure be hung up by the loop 18.

I claim: I

1. In a booklet, the combination of a cover having a substantially flat U-shaped back form-mg a pocket, said cover being flexible longitudinally thereof, a plurality of fastening means lying adjacent to the ends of the back and securing in direct contact with each other the sides of the U-shaped back to form an effective dovetail pocket having a neck with a constant perimeter, said pocket being opened by flexing apart the sidesthere'of at a point between said fastening means, and a filler inserted into said pocket when the same is opened as aforesaid and having points interlocking behind said fastening means,

2; In a booklet, the combination of a cover having a U-shaped back forming a pocket,- said cover being flexiblelongitudinally thereof, a plurality of fastening means lyin'g' along the back and securing together the sides thereof in direct contact to form an effective dovetail pocket therebetween having a neck with a constant perimeter, said pocket being opened between said fastening means by flexingthe pocket, and a filler which is inserted into said pocket when the same is opened'as-aforesa-id, and having a tongue to look behind said fastening means of larger size than the size of said neck-,said cover and filler having sufficient stiffness to lie flat when assembled;

3. In a booklet, the combination with a filler having a locking tongue, of a cover having a thin flexible back and a pocket in said back having a longitudinal opening formed therein of smaller size than the size of the looking tongue, said opening being ex p ausible transversely by flexing the sides of said pocket away from each other between the. ends of the pocket and about the edge of said back, so as to render said tongue insert- .able into said pocket through said opening.

an opening between the sides of the pocket, said opening being of smaller size than the size of the locking tongue, said pocket having a substantially straight line back opposite to said opening, said sides being secured together against movement toward or from each other at the ends of said opening, but

said sides being flexible away from each other between the ends of said opening and about said straight line back for the pur- 10 pose of expanding said opening to receive said tongue.

In testimony whereof I aflix my signature. CLARENCE DOUGLAS BROWN.
