This invention relates to book binders and it has particular reference to a bind'er'adapted to hold a plurality of sheets or leaves w th;

in a cover in a detachable manner.

lore specifically,, the invention contemplates the provision of a binder havmg' a cover within which are disposed a number of binge members or pins having fastening devices pivotally mounted thereon for detachable interlocking engagementwith other elements adapted to hold the leaves together.

In the specific .embodiment of the invention hereinafter described and illustrated, thefastening device is formed with a plate andslide" which, by propermanip'ulation, either reveal or close an aperture of suchsize as to permit of the passage therethroughof a stud head The stiid head is formed on a plate orstrip provided with prongs forimpaling a number of sheets of paper. When the aperture 1n the fastener is revealed, 'the fastener may be dislodged from or engaged with the stud head, to permit of the addition or removal of.

., sheets, and when the aperture is closed around the stud head, the leaves are firmly within the cover. Associated with the fastening assembly and forminga part thereof are one or more spacers which are employed'to I obtain the correct spacing of the pivoted i of a stackof assembled leaves.

fasteners relative the thickness-of the binder and included leaves, and also to reinforce the book cover and to maintain the parts proper relation; v

.The invention provides a book binder of the removable leaf type which is simple in construction, which retains the sheets firmly in place, and which permits of the removal or insertion of a leaf 'on either front or back The various objects and advantages of the invention may be understood from the following description of a specific embodiment of the principles thereof, illustrated inthe accompanying drawings, wherein, Z

Fig. 8 is a fragmentary perspective view of an assembled book binder with the'fastem device;

ing device detached from the leaf-imp'a'ling- The cover unit may be similar in construction to any type of book cover; The portions 11 and 12 may be stiif or flexible but the p'o'r-1 is a cross-sectional view taken on the line 3 8 of Fig. 1,.showing the construction tion 13 should be flexible as'is the case with c all types 'ofbinders.

On the inside'fa'ces of the portions 11 and 12 adjacent "thejunctions' of these portions with the back 13, are a plurality of hinge members 1 1 which are riveted or otherwise secured to the covers as indicated by the numeral 15. I Any number of these hinges may be employed depending upon the size of the'book. In the drawings four hinge members are shown and this will usually s uf fice for ordinary purposes, 'Each hinge member 14 is formed of 'sheet-metal or similar material and is provided with spaced pin bearings '16 adjacent its edge, which is adapted to be disposed adjacent the junction of the front or back cover and'the back 13 of the cover 10. The bearings 16 may be formed by rolling the edge of thesheet material into cylindrical form; The bearings 16 are spaced andthe metal is cut awaybetween them, as

indicatedby the reference numeral 17, to.

. provide a pocket in which other elements of is closed. It is desirable to position pairs of hinge members 14 in aligned relation on the covers 11 and 12.

A plurality of pins 18, provided with bent ends 19 to facilitate their insertion or removal, pass through the pin bearings 16. Mounted upon. the intermediate portion 21 of the pin 18 is a fastening device indicated generally by the reference numeral 22 and shown in detail in Fig. 6. device consists of a plate member 23 provided along one edge with a cylindrically turned portion 24 forming a bearing adapted to surround the pin 18. A portion of the same edge is not curled however, but formsa straight projecting finger 25. which limits the rotation of the plate 23 on the pin 18. This limitation of rotation facilitates manipulation of the fastener as a unit. The opposite edge of the plate 23 is bent at right-angles to form a flange 26 which serves as a guide and retaining means for a slide member 27. On the face of the plate 23 is a headed stud 28 adapted to pass through a slot 29 formed on the slide 27. Belowthe stud 28 in the plate 23 is a circular aperture 31.

The slot 29 formed in the slide 27 is elongated and it terminates at one end in an enlarged circular portion 32 of substantially the same diameter as the aperture 31 in the plate 23. The slide is also formed with angularly offset ends 33 and 34. The two elements, (the plate 23 and the slide 27), are interlocked for sliding movement by psi-.

-, tioning the slide 27, formed in the manner shown, over the plate 23, and subsequently passing the stud 28 through the plate and the slot 29. Or, one end of the slide 27 may be straightened out and the portion 32 of the slot 29 positioned over the stud 28 so that the slide 27 may be moved along the plate 23 with the head of the stud 28 engaging the surface of the slide 27 adjacent the narrow portion of the slot 29. Then the straight end of the slide 27 may be bent into the position illustrated.

" When assembled, it will be apparent that movement of the slide 27 over the plate 23 in one direction permits of the registry of the apertures 31 and 32, while movement in the opposite direction reduces the effective area of the aperture 31 by positioning the'narro'w portion of the slot 29 over segments of the cylindrical hole 31.

This 'key hole lock type of fastener is pivotally mounted on the pin 18 between the pin bearings 16. It is adapted to be swung toward or away from a pile of sheets 35 which may be assembled in the binder.

i As illustrated best in Fig. 3, the pile of book leaves 35 are provided with a plurality of aligned marginal perforations 36, which permit of the passage of leaf-impaling means collectively securing the sheets together. The impaling means herein delineated consists of v a pair of elongated flat metal plates :37 each This fastening of which is provided with alternating long hollow leaf-impaling bars 38 and short complementary studs 39. If desired, the bars 38 may be made in two sections that may be screwed together in order to permit of the linear adjustment of the bars. The outer section of each bar 38 is formed with longitudinally extendin aperture adapted to re ceive the pin 39 formed on the opposite plat 37. It may be observed that with this-con struction, either plate 37 may be removed from the stack of leaves 35 together with a number of leaves, so as to give ready access to a sheet adjacent either face of the stack without destroying the alignment of the apertures 36.

Disposed on the outer surfaces of the plates 37, and to be aligned with the apertures 31 in the plates 23, are studs 41 formed with a recessed neck and an enlarged head 43. When the fastener is brought over the stud 41 with the slide 27 so moved as to reveal the maximum effective area of the aperture 31, the head 43 of the stud 41 be pushed through the now aligned apertures 31 and 32, thereby effecting the engagement of the plate and the fastener 22. By means of this immediate connection the stack of leaves 35 may be firmly bound between the covers 11 and 12 by sliding member 27 in the opposite direction, so that the narrow portion of the aperture 29 engages the under side of he head 43.

This construction permits of the ready in troduction or removal of a sheet from the stack 35 and the change may be made by operating the fasteners 22 secured to either front or rear coverof the book. The leaves are firmly bound in position when the fasteners are locked, and hence the assembled volume possesses the desirable. features of a permanently bound'book while retaining the feature of interchangeability of leaves sought for in loose leaf binders.

While the binder as thus far described is, in and of itself operative and highly useful, nevertheless it is susceptible of improvement by the inclusion of a spacing strip which serves to strengthen the binder and to effect a great range of adaptation of the book cover to stacks of leaves of varying thicknesses. This spacing strip is referred to in the several assembled features bythe numeral 45 and it is illustrated in detail in Figs. 5 and 7.

The spacing strip is positioned between opposed pins 18, the recess 17 of the hinge member 14 being so dimensioned as to accommodate pin bearings formed on the strip 45 on the mid portions 21 of the pins 18. Each strip 45 is made in two parts, and advantageously is formed of thin and resilient sheet-metal. One portion, 46, is formed along one edge with spaced pin bearings-47 and is also formed with a plurality of centrally disposed regularly spaced holes 48. The other portion, 49, is likewise formed with pin bearwith slots 54 which extend below the surfaceof the portion 46.

' Extending through the slots 54 and under the lower surface of the portion 46 is a bow spring of thin sheet-metal, having curled ends 56 to prevent its removal from the slots. The'bow 55 is provided at its mid-portion with a pin 57 that normally passes through a registering hole 48 in the member 46 and the hole 52 in the portion 49, thereby locking the portions 46 and 49 together. When the curled ends 56. are squeezed between the fingers, however, the how 55 assumes the position shown in dotted lines in Fig. 5, when the pin 57 clears the holes 48 and 52, and so permits of longitudinal movement of the parts 46 and 49 to another and more desired position.

In assembly, the portions 46 and 49 are positioned between oppositely disposed hinge members, the pin 18 holding a spacing strip. section and a fastening unit 22 to each meniber 14. Depending upon the thickness of the stack of leaves 35, the length of the strip 45 is varied so that, when the book is closed, as indicated in Fig. 4, the strip 45 is of proper length to relieve heavy strains from thefieX- ible back web 13. In closing the fasteners on the stack preparatory to locking, it will be found that proper adjustment of the strips 45 facilitates operation, the fasteners 22 swinging into the desired position by the link action of thestrip 45.

, From the foregoing description, it will be apparent that I have provided a simple and rugged structure for firmly binding leaves together in more or less permanent relation, and that the principles of the invention permit of wide departures in the various physical embodiments which may be designed. It will be understood, therefore, that I do not desire the invention to be limited to the specific embodiment described, but that I intend to include such other structures as embody the features set forth in the following claims.
