LOOSE-LEAF BINDER Fified April 29. 1942 Bi" AGE/V Patented July 27, 1943 UNITED STATES; PATENT/OFFICE Harold E. Baug hman; Glendale, Calif assignor to Aero Publishers, Inc., Glendale, Calif.

Application April 20, 1942, Serial N6. 439598 7 claims. (o1; 12 9 1) V This invention relates to an improved looseleaf binder for note-books and the like, and has accordingly an object of this invention toprovide an improved loose-leaf binding arrangement for semi-permanent records, such as catalogs; service manuals, or the like, wherein replacement or supplemental material is to be added at in- V tervals. I I I In a previous application, Serial No. 405,340,

filed August 4, 1941, I disclosed a loose-leaf binding arrangement wherein a series of continuous rings were formed with marginal metal strips embedded in the backbone. Thepresent invention permits complete elimination of metal parts and also utilizes individual circular or semi-circular rings which may be cut from hard plastic tubing of a wide variety of materials and colors.

It is accordingly an important object of this invention to provide an improved and simplified loose-leaf book backbone that eliminates the need of any metal, and in which the leaf retain-.

ing rings can be rigidly supported and simply assembled in the backbone.

It is a further object of this invention to provide an improved and simplified lose-leaf binder closely approximating the appearance and arrangement of a permanently bound book, the

filling material having open stemmed T slots per-.

mitting its ready insertion and removal from continuous rings retained in fixed relationship to the back of the book, so that the book closely resembles a bound book which can be imprinted in the conventional manner.

It is also an object .of this invention to provide an improved and simplified loose-leaf book construction wherein continuous semi-circular securing rings are individually supported in a folded and glued cardboard backbone by means of a supporting non-metallic strip out out to receive a portion of the rings and having resilient tongues struck from the strip projecting through the rings to lock them into the apertures in the strip, the cardboard being folded and glued over.

The circular the non-metallic strip and the free ends ofthe tongue to provide a rigid backbone into which the rings' are'partially embedded; the assembly being further retainedin position by the usual inner lining of the book ccversand/or by a finishing fabric strip suitably slotted to be applied over the securing rings in contact with the backbone. p

Other and further objects and advantages of my inventionwill become apparent as the description of the invention proceeds. V

In the accompanying drawing- Figure I is. a perspective view of an opened loose-leaf book showing the construction of thisinvention, parts of thelining material and backbone being broken away to disclose details of the construction; and including a preferred typical sheet of paper for use therewith. Figure II is a fragmentary perspective of the non-metallic strip which locates and supports the securingjrings, one ring being shown in place in an aperture, in the strip.

Figure III is a cross-section of this device of' Figure-I showing details of the continuous securing rin gmounting, g

I Figure IV is a section through a modified form of this invention corresponding to FigureIII, the

7 ing conditions.

modification embodying the use of semicircular rings. r

Figure V is a section throughanother modified form of this invention usinga semi-circular ring wherein the base is deformed to more solidly seatin theaperture therefor. r r Asshown on the accompanying drawing, the invention relatesto" mounting continuous circular or. semi-circular D shaped-securing rings [0 relative to the covers and back of a book structure; boards ll, in the case of stiff covers, and a back l2, an outside cover material l3 being applied thereto inthe usualmanner. to provide hinge lines 14. The inside surfaces of the covers may befinished with lining paper l5, and an inside lining fabric l6 applied to the back if desired.

The. securing rings I!) are conveniently transverse sections of extruded or cast plastic tubes which can be formed in a variety of cross-sections.- Almost any thermo-setting-synthetic resin plastic that'canbe suitably formed will be satisfactory for the-purpose, so--that the choice may be decided by cost and availability under exist- An example is phenolic formaldehyde resin or urea formaldehyde resin.

The use of continuous rings makes it desirable to use marginal T slots in the filler material,

the 'bookcovers comprising cardboard.

. place.

which I have found can be readily inserted or stripped from the rings without damage to the sides of the T slot in the paper. Preferably the paper filler should be peeled oil the rings with a movement aligned with the axis thereof, rather than to pull the paper out from the free edge of the book.

The securing rings are seated in apertures I! in a non-metallic strip. [8, a central tongue [9 being out into 'the strip to pass through the ring and 10 press it into the apertures, the resiliency of the tongue being sufficient to permit it to be sprung upwardly to allow the ring to be slid into place f under the free end of the tongue. I

The supporting strip may be made of plastic, 15. fibre board, or thin plywood, an exam-plebeing a plain or colored cellulose nitrate plastic.

In each of the forms of the inventionthe-suoporting strip i3 is bound in a triple layer of card-e board forming a backbone which may be an inner backbone supplementing a cover backbone or may itself formthe sole backbone ofthe book bind ing. .The triple cardboard backbone comprises 'a central. layer ZB underlying the supporting strip f It is convenient to. provide a fabric finish and cover strip I6 whichmay have slotted: margins to extend around the, rings Ill ormay be slotted as at 23 to slip over the. rin s to be glued in Such a cover strip acts as a trim to the central portion of the inside of the covers, and

strengthens the hinge lines l4.

Figure III is a considerably enlarged crosssection wherein the several: layers of the backbone have been shown somewhat idealistioall-yfor clearness. Actually the several cardboard layers are, glued together andto the securing 40 strip [8 to form a substantially solid-lamination,

so that the margins will be compressed into con-. tact; 1 I

It will be evident that circular rings l-llcan be used as in Figures I and III or a'semi-circular or; D ring Ill as in Figures IV or V, the latter having oi fset portions 24 in the stem or flat side which seat solidly into the apertures inthe supporting strip I8.

I-t will thus'be' seen that I have invented an improved and simplified loose-leaf book wherein the'backof the book has the appearance of a permanently bound book since no rivets are required to retainjthe securingrings'inposition, wherein the capacity ofthebook; is; increased Without liability -of'wedging the outside sheets thereof between the covers andthe rings, andwherein the entire construction avoids the use ofmetal while providing a substantial and rigid construction.

Having thus described my invention and the present preferred embodiments thereof, I desire to 'emphasize the fact that'rnanymodifications may be restortedto in a manner limited only by a just interpretation of the following claims.
