Application filed October 19, 1914. Serial No. 867,381.

To all whom it may concern Be it known that I, Gnoncn H. JENKINS, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain newand useful Improvements in Books and Binding Devices Therefor, of which the following 18 a specification.

This invention relates to a bound book such as results from binding loose leaves into permanent form, and also to the means by which such binding is elfected.

Among the principal objects of my invention is the provision of a binding, secure, inexpensive and capable of being performed by any one unskilled in such matters; and a permanent binding of loose leaves capable of being efiected while still retalned wltlnn current or temporary covers.

It is common practice in business records to utilize a quantity of loose leaves securedbetween current covers and to add from time to time to the book thus formed as additional leaves are required. It is usual to transfer the contents of such abinder to another pair of covers and bind the same permanently therein. The book thus formed may then be filed away as a permanent record. The meansheretofore employed for elfecting a transfer of loose leaves from current covers to permanent covers has usually involved considerable expense and skilful manipulation' In'the present invention I have sought, therefore, to ClQVlSGZL construction of binder which enables a transfer of leaves in the most expeditious and economical manner.

In the drawings: Figure 1 is a crosssection through a quantity of leaves between permanent and current covers as arranged at the time a permanentvbinding is to be performed; Fig.2 is a cross-section through one end of a book completely bound Fig. 3 is a view similar to Fig. 2, showing a modified form of binding; Fig. 4: is a side elevation of the book showing a slightly different relation of the parts during the binding operation than is exhibited in Fig. 1; Fig. 5 is a plan view of a quantity of unbound leaves arranged between clamps to facilitate the binding operation; Fig. 6 is a cross-section on line 66 of Fig. 5; Fig. 7 is a view similar to Fig. 5, showing a modified form of clamp construction; and Fig. 8 is an end elevation showing the construction exhibited in Fig. 7.

Fig. 1 represents a quantity of leaves 9 bound together for current use between covers 10. Posts 11, provided with screw caps 12, are illustrated as an appropriate binding for this purpose. The covers 10 differ from those ordinarily employed chiefly in that a number of openings 13 are provided in the plane of binding.

At the time a permanent binding is to be performed, it is contemplated that permanent covers 14 shall be arranged in position as shown in Figs. 1 and 1. Ordinarily one of these permanent covers is laid adjacent one of the current covers at the time the leaves are first inserted in the book, so that when a permanent bindingis to be effected it is necessary only to remove the temporary cover which lies adjacent the threaded end of the postin order to install the other permanent cover in place. I would have it understood that it isnot necessary to replace in position the current cover 10 which was removed to allow positioning of the second permanent cover, asmight be inferred, perhaps, from Fig. 1, but that the binding may be performed as well by compressingthe leaves through the medium of the caps which screw upon the posts 11 pressing directly against the permanent cover as shown in Fig. a.

When the leaves are arranged between the permanent covers in this manner and the desired compression is obtained, I contemplate driving a number of nails 15 or other pointed elements into the leaves. The places at which these nails are driven may be determined by the openings 13, which are of suliicient size to enable the nail head 16 to pass therewithin. The permanent covers need not have such openings, but may, if desired, be marked to indicate advantageousv positions in which these nails should be driven, or, in lieu of such marks, be provided with small holes to facilitatedriving' in of the nails. As will appear from Fig. 1, these nails should be of suificient length not to pass through the entire stack of leaves, but rather that their shanks should overlap to some extent through the central portion of the book when the nails are driven in from opposite sides thereof.- Also, I prefer to group the places at which the nails shall be driven, so that the pressure caused by displacement of the material as each nail forces its way through the book will cause a slight increase in frictional pressure against the adjacent nail, thereby effecting a tighter and .more secure binding.

In Fig. 3 is shown the use of nails 15 to bind leaves together which are slightly longer than the width of the book. In this instance it is necessary to clench the nails, as shown in the said figure; otherwise the binding is the same as the other forms shown and described.

It is apparent when the leaves composing the book have been permanently secured between the covers that the screw caps may be removed from the posts and the temporary covers be withdrawn to be again available for use with other leaves. The, bound book is held together between the permanent covers solely by frictional engagement of the nails within the leaves. It is possible, of course, that the nails might have a tendency to loosen and withdraw, in which. case the binding would eventually be destroyed. To prevent this, as well as to give the book a finishedappearance, I contemplate adhering or securing to the back of the book and the adjoining edges of the covers a strip of flexiblematerial, such as the backing 17 shown in Figs. 2, 3 and 4:. For convenience this backing may be initially secured to that permanent cover which was first installed Within the current 7 covers, so that at the time the said current covers are removed one end of this backing is all ready to be secured in place. It is manifest, therefore, that the presence of this backing which overliesthe adjacent edges of the permanent covers, and is secured thereto, resists effectually any tendency for the binding of the leaves to become loosened and destroyed.

In Figs. 5 to 8, inclusive, are shown leaves bound permanently together by the same means as is illustrated in the other figures.

vIn theselatter figures, however, theleaves are not secured initially within any binder, but are loose and unboundat the time they are arranged for binding. For this purpose I provide a pair of clamps 18 at the extremities of which posts 19 and screw caps 20 are so arranged as to compress between the clamps a stack of leaves to be bound. These clamps are provided with openings 13 simi-' lar to those shown in Fig. 1, through which the nails thatefiect the binding are driven.

In order to accommodateleaves of different Widths and to prevent bending or spring ing of the plates, I arrange intermediate the posts 19 one or more lips 21 intermediate the ends of the plate which project out just beyond the edge of the leaves to be bound. Throughthis lip a threaded post and cap extend, similar to that'employed elsewhere, so that a compression of the leaves inter mediate the ends thereof may easily be effected. This form of clamp construction is clearly shown in Figs. 7 and ,8. After the nails are driven to secure the leaves and permanent covers together, I contemplate the application of a flexible backing in the same manner as is illustrated in Figs. 2

and 3.

I have usedthe term nail to designate the element which permanently secures the leaves in bound form. Ordinary pointed nails or threaded screws will answer equally well the purposes of this invention. If pre-' ferred, short holes may be drilled in the leaves to facilitate driving in of the nails or screws, but the use of such an expedient is entirely optional with the operator.

I claim: I r I 1. In combination with a quantity of leaves arranged in book form, a pair of clamping elements between which the leaves are held together, means for maintaining said elements in clamping relation located outside of the book body, said clamping elements being provided with a plurality of openings through each of which a pointed element may be driven to effect a binding of the leaves, said clamping elements being removable from the book without interference with said binding elements.

2. In combination, with a quantity of leaves arranged in book form, a pair of clamping elements between which the leaves are held together, means located outside of the book body for maintaining said elements in clamping relation at a point intermediate the ends of the bound edge of the book, said clamping elements being provided with a plurality of openings througheach of which a pointed element may be driven to effect a binding of the leaves, said clamping elements being removable from the book without interference with said binding elements.
