HERNAN, F BALTIMORE, MARYLAND, ASSIGNOR TO AMERICAN BANK STA- TIONERY COMPANY, OF BALTIMORE, ILRYLAND, A CORPORATION OF MARYLAND BOOKBINDER i Application led February 1, 1930. Serial No. 425,269.

This invention relates to improvements in book binders, and will be hereinafter described as a binder for check books, altho it will be understood that the invention is applicableto book binders of general use.

a In the manufacture of check books, the cost of the binding thereof is generally borne by the check paper manufacturer or printer, so that an elimination of a mechanical operation or operations in the steps of binding the checks in book form represents la substantial economy to the check manufacturer. While check book bindings are generally of an inexpensive character since the constant handling of the check book by the user results in the cover being generally well Worn when the book is exhausted of its checks, it is desirable that bindings of this character be of a permanent nature, whereby the checks may be maintained in assembled relation during the life of the check book, and also to permit the check stubs to be saved in book form by the check user for record purposes.

It is accordingly an object ,of the present invention to provide a binding for books, such as check books, which is relatively inexpensive and which further reduces to a minimum the mechanical operations of binding. A further object is to provide a permanent binding of a durable but inexpensive nature. A furtherobject is to provide a book binding which results in a sightlyand attractive appearance of the bound book. A further object is to provide a book binding in which the binding elements are engaged in a single operation in a cooperating and permanently locked relation.

Other objects will be in part obvious from the annexed drawings and in part indicated from the following analysis of this invention, in which reference is made to the accompanying dra-Wings illustrating an embodiment of my idea.

In the drawings- Fig. 1 illustrates in perspective a partially bound check book in accordance with my invention; Y

Fig. 2 is an enlarged broken-away section of the post and socket element-s of the bindlng;

Fig. 3 is a section thru a modified form of binding socket and associated binding post;

Figs. 4, 5, 6 and 7 represent diagrammatically various types of locking elements to be contained in the socket member; Figs. 8, 9 and 10 are illustrative of various shapes of locking heads disposed at the ends of the binding posts in accordance with my invention;

Fig. 11 is a section thru a binding strip forming a part of the book cover having associated therewith a modified form of binding socket.

Referring now to the drawings, the. reference character 10 indicates generally a plurality of check sheets, each provided with openings 11 thru which extend posts 12 forming a part of the binding structure to be hereinafter described. It will be understood that the check sheets are threaded on the posts 12 and assembled in overlying relation, and arc thereafter bound in the cover element generally designated by the reference 13. The ends of the posts 11 which ends are hereinafter termed lockings heads, may cooperate with socket elements A, B, C and D disposed on spaced parallel binding strips 14, 15 which preferably form a part of the book cover 13.

By reference to Fig. 2, wherein is shown one form of locking arrangement, each of the socket elements A, B, C, D, may comprise a plate 16 with which is associated a casing 17 including a marginal flange 18 seating against the plate 16 and provided with tongues 20 which extend through apertures in plate 16 and are adapted to be forced thru the body of the binding strips 14, 15 and clinched thereover, thus to secure the socket in fixed relation preferably on the relatively opposed surfaces of said binding strips. The marginal flange 18 of the casing 17 may also be provided with tongues 21 extending thru the plate 16 only and clinched over, thus to hold the said plate and casing 17 in fixed spaced relation.

The casing 17 is provided with a central aperture 25 which is preferably circular and in alignment with an aperture 26 in the plate 16 and also with an aperture 27 in the bind-` ing strip 14. l/Vithin the socket member and disposed. between the plate 16 and the casing "17, there is positioned a locking element such as a spring 30 to be hereinafter more fully Y i described.

The postsll, on which the sheets are assembled, comprise a body portion 31 Whichl may be circular Vin cross section and preferi ablyfaltho not essentially, of a slightly greatl vided With abase or locking shoulder 35. The

' er diameter than that of the aperture 125 in thecasing 17; `Thesaid portion V31 terminates in an 4abrupt shoulder 32, from Which extends a portion 33 of reduced. diameter terminating in a. locking head 34 which is progrea-test diameter of the head 34 is prefer- Y ably less than the diameter Vof the body porition. 31 ofthe postV and is such as :t0 permit the headto pass thru aperture of plate 17.

Asvvillbe apparent from/Fig. 2, when the' socketis pushed-:down on thehead Vwhich j passes. thru aperture 25 therein, the Vlocking 4'spring-Bois distorted yor snapped over head 53.4, and thereafter encompasses'portion 33'of reduced diameter, the hea-d, by reason o-f its shoulder-35,r being thereafter permanently V.lockedWithin the socket member, iWhen so locked, the shoulder32abuts against the casing 17 and thus serves to limit the Vdegree of The axial 'lengthv of the reduced -portion 33 .andf27- of the plate 16 and 'binding strip 14,

l respectively, the head terminating short .of

the "outer side ofthe cover or bindingv strip. It is' here importantto note that the shoulder f32jengaging the plate 17 throughout its-pe- ;rifp'hery Y serves Ito j prevent `any considerable tipping or oscillating of the 'post 11 about its gripped head, and disengagement of the head 34 from spring 30, as is usual in knovvn forms of temporary'sn-ap.fasteners, is thus-posii' ltively prevented. Further, the interior depth lofthe socket, that is to say, the space between the inner surfaces ofthe plate 16 andcasing isnot much greater than the thickness of spring 30, thus maintaining'v the Y spring Vagainstmovement i'n thedir'ection '0fthe axis of post V11. As aconsequence,the'head 34is rigidly` and permanently locked Within the socket v-upon 4completion of the 'locking action'. By reference lto Figs. 4, 5, Gand the spring 304 may,-as shown in F ig. 4, comprise a', the end portions of Whichare internally bent and `curved to provide thel` radial or i curved locking portions 305. In the spring consitructionjof F ig.l 5, the locking .portions ofthe spring comprise the straight endpor= iposedportions 30d,3.0e, a triangular locking v element having a three-sided bearing .on the portionA 33 of the post `11. In the spring con-V tion 300 forming with the bent angularly disstruct'ion of Fig. 6, theends 307g, 30g, arebent reversely on the internally bent portion to thus provide a tWo bearing contact with maximum spring action on the'portion 33 of the binding post. InvFig. 7 the ends 30j, 30k of the spring 30 extend along a straight line and in parallel relation With each other, thus toA providey a two-point bearing on the portion 33 ofthepost 11. Y Y

Y* InFigs. 8, 9 andlO, various shapes of locking heads arey diagrammatically illustrated, thehead 34 of Fig. Srconforming'to a cone over Which-the spring 30 is snapped. VIndiig.

9, the head 34a is generally semi-circular in cross section, Whereas the head V346 of Fig. 9 Vcomprises va cylindrical portion 340 terminating f in a portion 34d in the nature ofv a truncated cone. Other shaped heads may be substituted as long as they are pro'- Avidedvvith locking shoulders or flatbases 35 extend-ing perpendicularly to the axes of the posts to cooperate With the springs to lock the posts undetachably with the sockets.

Iny assembly, the sockets are preferably/:attached tothe binding strips 14, 15 of the cover 13 (which may beshippedorst'ored flat) lin the relation illustrated in Fig. 11, that is to say, the vsockets A- and C tor be positioned in spaced overly-ing relation when the binding strips 14 and 15v are brought in their binding relation, and the z sockets B; and VD similarly disposed. The posts 11 are .thensnapped into the sockets fC and D and permanently locked therein. After the sheets lOlhave been threaded'on the posts so positioned, the.y binding strip 14 of the uppercover element is 'broughtfover the posts 11 and snapped onto the upper locking heads 34 thereof so as to be thereafter associated in fixed locked relation. The binding ofthe sheetslO Within the cover 13 is thus accomplished by merely engagingy the socket elements with the locking heads of t-he posts and'vvithout the necessity of V mechanically distorting :any ofv Ythe .elements, and similarly Without the necessity of Vexpensive and timetaking mechanical bind- Ving operations.

The sockets A, Gland 311),., indicated in Fig. 1, .are disposedonthe opposed surfaces substantially obscured .the1disposition of the paperfor fabric coverings 36,. forming a l all depth of thesocket being relatively small aspring. Wire bent throughout an outer curve and the flocking heads being substantially 'housedin apertures 27 of the binding Strips Byreferenceto. Fig. 3;, there` isfiillustrated i Va modifiedV formof socket .element and attachmentthereforwith the binding strips 14, 15. lnxthe emb. odimentV shown, the strip 14 is provided vvith itsY aperturel 27l thru which eX- tends'a'tubular rivet 38 with Vits outer end ofthe binding strips 1.4,.andlg5, and may be l fiange 40 clinched over a Washer 41. The rivet at itsother end is enlarged to form the casing member 17a `constituting a socket element, and as a'consequence, the casing 17a enclosing the spring 30 is rigidly associated With the binding strip 14. Fn this modified form of binder, the post llhas one end only provided with the snap head, the other end being provided with a rivet end 33a turned over a locking Washer 41a as at 33?) for permanent attachment to one of the binding strips 14, 15. It Will be understood that the post 11 and associated locking heads which are illustrated as solid, may be formed of sheet metal and pressed into tubular shape, thus to facilitate the formationV of the rivet end 33a thereon.

In Fig. 11, there is shown a further modified form of socket element and its attachment with the binding strip, in which a sheet metal strip 42 adapted to underly the binding strip 14 throughout its length is provided with depressed portions forming a casing 175 of the socket element. A base plate 16a provided With clinching teeth or prongs 165 forms with the pressed out casing portion 176 an enclosure-for the locking spring 30. It is understood that in the construction of Fig. 11, both of the casings 17?) are formed in the single metal strip 42 and spaced in a manner similar to the arrangement of sockets A and B of Fig. 1. The said strip may be rigidly fixed on the binding strip 14 by end tongues 43 or side tongues 44, or both?, as the circumstances may require. v

It will be seen that the several objects of the invention are achieved and other advantageous results attained. As many changes could be made in carrying out the above invention, Without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
