H. AUBURN LOOSE LEAF BINDER Filed April 21, 1943 Ilill Patented Jan. 11, 1944 LOOSE-LEAF BINDER Hubert Auburn, Mount Healthy, Ohio, assignor to The Tenacity Manufacturing 00., Lockland, Ohio, a corporation of Ohio Application April 21, 1943, Serial No. 483,912

4 Claims.

This invention relates to loose leaf record books.

An object of the present invention is to provide a loose leaf binder of the record book type, the covers of which are hingedly secured to the back member without resorting to the use of metallic hinges.

Another object of the invention is to provide a loose leaf binder of the record book type with non-metallic cover hinges which are so constructed as to provide a hinge structure which compares favorably with metallic hinges both from a structural and use standpoint.

Still another object of the invention is to provide a loose leaf binder of the record book type having the hereinabove characteristics which may be rapidly and economically manufactured, for the most part, from non-critical materials.

Heretofore it has been common practice in the art of manufacturing loose leaf binders of the record book type to hingedly attach the cover members to the back of a record book by means of metallic hinges, such as, by way of example, are disclosed in the H. Auburn Patent No. 1,891,037, dated December 13, 1932; the E. C. Hazel et al. Patent No. 1,925,719 dated September 5, 1933; or the J. Cooper Patent No. 2,067,846 dated January 12, 1937. Such metallic hinges comprised, broadly speaking, a pair of wing members one of which was secured to or made integral with a metallic back member and the other wing member of which was secured to a cover by means of riveting, or the like, as disclosed in the hereinabove enumerated patents.

The object of the present invention is to pro vide a loose leaf binder of the record book type in which the number of metallic parts has been reduced to a minimum without sacrificing the desirable structural features which should be embodied in such devices. Devices embodying teachings of the instant invention permit sixty percent of the metal which was formerly used in similar binders to be saved, with a fifty percent reduction in the weight of the finished product.

These and other objects are attained by the means described herein and disclosed in the accompanying drawing in which:

Fig. 1 is an end view of a. loose leaf binder of the record book type embodying the teachings of the present invention.

Fig. 2 is a sectional view of the record book of Fig. 1 with the covers in an open or extended position.

Fig. 3 is a perspective view of a loose leaf binder of the record book type with-the various component parts thereof in a separated or spaced-apart relationship for clarity of detail and understanding.

The binder comprises, generally speaking, a back III, a pair of cover members I I and a pintle rod assembly I2 which comprises a pair of pintle" rod housings I3 secured in spaced parallelism along the opposite edges of attachment plates I4.

With particular reference to Fig. 2, it will be observed that back IIJ comprises a wooden form I5 having an inner face 40 and an outer face 4|. If desired, form I5 may be fabricated from any other non-metallic material such as, by way of example, plastic, or the like, having due regard for size and shape. A plurality of bolt holes I6 may be drilled or otherwise provided through member l5, said holes being disposed along the longitudinal axis of said member. Preferably, the outer end of each bolt hole I6 terminates in a nut receiving recess I 1. Member I5 may be covered with a canvas, denoted generally by the numeral I8, and the canvas may then be covered with leather, or other suitable finishing material denoted generally by the numeral I9. The ends of the covering material may be turned inwardly over inner face 40 of the back form I5 to which it may be secured by means of gluing, tacking, or the like. It will. be understood that before applying the canvas and leather coverings to back form I 5, a nut 20 will be inserted in each of recesses II, whereby said nuts will be concealed from view by reason of the canvas and leather covers.

Cover members II may likewise be fabricated from suitably shaped core members or cover boards 2| which may be made from wood, cardboard, or other suitable material made up to the desired size and beveled. A heavy piece of canvas 22 may then be glued directly to the inner face of boards 2I with a free edge of canvas projecting forwardly from inner edge 23 of cover board 2|. As disclosed in Fig. 3, the width of canvas 22 may be of a dimension considerably less than the width of cover board 2|, said canvas extending forwardly from free edge 23 two or three inches.

The outer face of the cover member may then be provided with a suitable finish covering 24 of leather, or the like, which may be glued directly to the cover board. As disclosed in Fig. 3, it will be observed that the ends of the finish covering 24 may be turned forwardly over the ends of the cover boards, and so as to overlie the ends of canvas strips 22, thereby providing a neat durable finishedouter edge 42.

After the covers have been lined, gold-tooled, etc., the outwardly projecting free ends of the pieces of canvas 22 and finish covering 24 are laid over and secured to the inner face of back by means of a plurality of tacks denoted generally by the numerals 25. Preferably the tacks are disposed in staggered relationship as disclosed in Fig. 3.

The pintle rod assembly l2 may then be secured to the back member by means of bolts which may be inserted through bolt Openings 3| provided in attachment plates [4, and which bolt openings are adapted for alignment with their respective bolt holes l6 provided in back member I 5. It will be observed that attachment plates is will overlie the heads'of those tacks over which they extend thereby effectively precluding accidental and/or unintentional loosening or withdrawal of said tacks from back member l5. In order to further secure the pintle rod assembly to the back member, a plurality of screws 32 (see Fig. 2) may be inserted through suitable openings 33 provided in lower attach- Inent flange or leg 34 of each pintle housing It and attachment plates l4, said screws extending through canvas 58, finish covering 59 and projecting into back member 15.

In the preferred embodiment of the invention, attachment plates i l may be relatively narrow, as disclosed in Fig. 3, in which event it is desirable to provide filler pieces 40 between adjacent attachment plates for the purpose of providing a fiat plane surface between the spaced pintle housings It. If desired, such filler ieces may be fabricated from cardboard, or the like. It is preferable that the outermost row of tacks 25 be aligned so as to be disposed beneath attachment leg at of the pintle housing It whereby such tacks will at all times be positively held in place. If desired, those portions of canvas l8 and leather 19 which are tacked to back member l5 may be likewise glued thereto, however for strength and durability it is highly desirable that at least one row of tacks be utilized for the purpose of securing the canvas and leather strips to the back member.

It will be observed that covers H are thus hingedly secured to the opposite edges of back ll! by means of a hinge comprising a thickness of canvas and a thickness of finish covering. Tests have indicated that such a hinge while considerably lighter in weight than a metallic hinge, is nevertheless quite as satisfactory as a metallic hingev Such tests likewise indicate that the present hinge will withstand the usual type of service and abuse to which loose leaf binders of the record book type are subjected to for a period of many years, wherefore it is seen that the life of the record book has not been shortened by reason of having dispensed with metallic hinges.

It should be understood that the present invention is not directed to, nor concerned with any particular type of means for actuating the pintle bars i which carry pintles 43. Such means may be fully automatic, semi automatic or manual, depending upon the particular usage to which the binder will be put.
