As illustrated in Fig. 5, the retainfound in th usu l p ssh p or in e ving member H is substantially ladder shaped and A. f r herfobject oi. the invention is the concomprises a plurality of cross members or rungs truc n' of a l l hi 15 p mGX-l 12 connected at their ends by the laterally ex- 40 pensive, and durable for the purposes intende tending side portions l3 and ii. If the cuts 40 thus providing, a binding which provides the extend consecutively between all of the apertures maximum in-utility and:appearancewith rela '4 and I, the portions l3 will be formed in a g l very 11 t f unitary construction similar to the portion I3,

' Fig. 1 isja plan view of a book in closed posi- I To assemble the device, the leaves 2 are stacked v tion; f w with the two cover leaves 3 side by side, the sur- 55 faces thereof forming the outer faces in' the finished book being adjacent one another, after which the portions ll of the retaining member H are passed through the respective apertures and cuts of the two cover members 3, then through the respective apertures and slits in the leaves.

, This engaginglof the retaining member with the leaves may be facilitated by flexing the leaves slightly so that each leaf will tend to separate at the knife edge cuts 6 and I, so that the retaining member may easily be passed as a unit through the leaves, after which the latter will readily resume their normal position and prevent any disengagement between the parts.

Following the engaging of the retaining member and leaves, the cover members are rotated in place, as shown in Figs. 3 and 4, the portions 13 and Ii of the retaining member (being adjacent the innerv face of one of the cover members so that the outward appearance is merely that of a plurality of rings passing through the respective apertures. Obviously, the retaining member I! could be inserted in the reverse direction; namely, first, through the leaves and then through the cover members, although this would not provide quite as secure an engagement as the former construction, and likewise, as a matter of choice, the portions 13 and I 3' could be positioned between any two leaves desired. Also, if desired, the cuts 6 and I could be curved and angular as well as in a single straight line and with the respective cuts formed transverse to one another so that-in either case, it would be necessary to bend or fiex the retaining member slightly when inserting it through the leaves, thereby providing a still more positive interlocking between the elements.

Illustrated in Figs. 7, 8, 9, and 10 is another manner in which the cuts 8 and 1 might be modifled. In this construction, the cuts II are in the form of very narrow slits, these being so formed merely as a convenience in assembling the device, and if desired, may be in the form of a out only instead-of the slit as shown. These cuts or slits extend directly to the and leaves, thereby indirectly connecting the apertures as do the cuts 8 and I in the first construction and as each aperture ll is provided with a slit, it is not necessary that one side member 23 of the ladder-like retaining member 2| be divided into sections similar to the portions I3 of the retaining member ll.

In assembling the latter construction, the cross members or rungs 22 are inserted into the apertures ll by passing them through the slits or cuts l1, each cross member being bent or twisted slightly during the insertion thereof into its respective aperture. The slits I] are extremely narrow and while they permit passing through of the cross members 22 when the retaining member is in a flat position, they would not allow undesired repassing of the cross members after they have been formed into apparent rings, in the completed binding,

During the engaging of the leaves and retaining .means, the two covers are positioned adiacent one another so that when the outer cover is rotated about into its normal position, the cross members 22 will extend around the adiacent edge of the leaves, as shown in Fig. 8, with the portions 23 adjacent one another similar to the first construction.

While we have shown the retaining member as an element separate from the covers, if desired.

cross members is formed subsequent to the assembly of the leaves and retaining member so that the cross members are engaged while substantially flat, thereby preventing injury to the same, 10

and also safely allowing some flexing of the members if necessary, Likewise, by providing a ladder-llke retaining member, a very strong binding is produced, free from weakened and small delicate elements, etc., thereby eliminating the comparatively weak comb-like structures previously used, thus ideally adapting itself to be made from paper and other materials which do not ordinarily favorably lend themselves to the preformed constructions old in the art. As the device is not preformed, any cuts made in the leaves or retaining members would at the most be not greater than the thicknms of the paper or other material used, in contrast to the old constructions where a paper retaining member would be injured and 25 tom if the slots were not constructed relatively larger. This construction would be objectionable as the increase in the size of the slots would decrease the eifectiveness of the locking action between the leaves and retaining member. However, by constructing the retaining member as a flat ladder-like structure, and assembling the device while in an unformed state, no distorting or forcing of the retaining member is necessary so that injury thereto is substantially eliminated.

Having thus described our invention, it is obvious that various immaterial'modiflcations may be made in the same without departing from the spirit of our invention; hence, we do not wish to be understood as limiting ourselves to the exact .10 form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

What we claim as new and desire to secure by Letters Patent is:

1. In a device of the kind described, a plurality of leaves having aperturesadjacent one end thereof, a flexible ladder-like retaining member having a plurality of cross members connected at their respective ends by laterally extending to portions, and a plurality of cuts in said leaves communicating with said apertures providing means for inserting said cross membersln said apertures to lock said sheets and retaining member to one another, said cross members extending through the apertures in said leaves, around the adjacent ends thereof, through the apertures in at least one other leaf with the lateral portions of said ladder-like retaining member adjacent one another, said cross members forming substane tially complete flexible rings.

2. In a device of the kind described, a plurality of leaves having apertures adjacent one end thereof, a ladder-like retaining member having a plurality of cross members connected at their respective ends by laterally extending portions, and a plurality of cuts in said leaves connecting adjacent apertures, the combined span of the apertures and cuts connecting the same being of a size to allow passage of a laterally extending 7 portion of said retaining-member through said leaves.

3. In a device of the kind described, a plurality of leaves having apertures adjacent one end I thereof, a flat. ladder-like retaining member hav- 76" ing a plurality of cross members connected at their respective ends by laterally extending side through said leaves, to lock said sheets-and retaining member to one another, said cross members extending through the apertures in said leaves, around the adjacent ends thereof, through the apertures in at least one other leaf with the lateral side portions of said ladder-like retain- 5 in member adjacent one another.
