whichA thefollowing is a specification.

The present invention 1s a cover and bindery for loose leaves or sheets of paper.

As far as applicant has knowledge, therey are twogeneral types of note-books orbindersotthe loose leat variety-namely, those which make use ot rings and those which make use of rods or posts to extend through openings in the leaves or` sheets to maintain them in position. The ring type of cover or binder has the disadvantage that the openings or eyelets ot the sheets easily tear out from the rings. binding of the leaves in this type of binder as they slide loosely on rings, and their liability of being torn from the rings is an annoying disadvantaffe. In the post type of binder there are generally found stud members or telescopingy rods which extend through the opening in the edges of the leaves and which hold the sheets bound together by compression. Binders ot this type are, however, not adjustable from the thickness ot' one sheet orp papervto its capacity because the minimum thickness ot the book corresponds tothe length of the members or posts in their i'ull telescoping or collapsed position.. This limitation or disadvantage is readily obvious, especially when one or two leaves or a relatively tewleaves arerequired in the cover.

lt is the object otl the present invention to produce a note-book or cover, which will open in suchA a manner tha-t, when laid-flat on a table, or used' as a held orv hand-book, the leaves thereof will; not close, and to produce a cover in which one or a plurality ot loose leaves may be bound and which will permit the ready and easy *removall of anyv number ot leaves or intermediate leaves' without necessitating the removalv of the other leaves from the cover.

The invent-ion further resides in the sundry details of construction, combination and arrangement of parts hereinafter more fully described and pointed out in the appended claims.

In thedrawings which illustratethepreterred. embodiment of the invention as at present. devised,

There is `no reall vFig. l is a longitudinal sectional view taken through the binding means of the book cover;

Fig. 2 is a rear end view ofkr the book or binder. j

Fig. 3 is on line 7 7. of Fig. 2 of the binder to illustrate the construction ot the binding mechanism.

Figure 4; is a fragmentary plan view of the binding end of` the book cover illustrating they particular formation of the sprinw 19.

Reierring particularly to the drawings, inwhich like characters refer to corresponding parts throughout the several views and inthe specification, the invention comprises a `front' or upper cover l and a relatively thickerback or tablet portion 2 both, prei:- erably, rectangularin shape and ot' rigid material. To the one edge of.' the tablet portion is hinged, as at 3, a binder block i which is preferably co-extensive with the said edge and mayV havel the same relative thickness as thevbody of the tablet 2. The cover-l is flexibly connected at 5 to a binder strip Georresponding to the binderblock 4..

The binder strip and/binder block lie oppositel and parallel' to each other and are equipped with means for binding loose leaves or sheets of paper-therebetween. The back 2 is cut away or mortised inwardly 'from the upper edge thereof to provide a recess 7 in its outer tace extending' transversely thereof. This recess may be oil2A suliicient depth to accommodate binder block l when-the book is opened;

'.lo permit the opened leaves a to be tin'nedl back underneath the book, the cover l ofthe book is hingedy or flexible transversely atthe point8,`the distance between the hinged or flexible portions o and 8 being oii'sliglitly greater width than the -binder strip Glin orderVv topermity this folding ot the book andi leaves.

'The parts l, 2, land may be all covered by a covering of? cloth, leather or other suitable material andthe hinged' members 4 and 6 are to be concealed by the covering insuch manner as to prevent any liability of'scratching or other-wise marring a. desk,

table, or the like.

The means vtor binding the leaves between a cover l andf back 2 of the-notebook comprise studs or posts 9, one, preferably, at each end portion of' the binder block il. Thesestuds 9 are slidably mounted in the block 4 and are, preferably, contained in tubular guides embedded in the block. The inner ends of the studs have laterally projecting therefrom lugs 11v extending through longitudinal slots 12 in the guide 10. A leaf -spring 18 is disposed in a recess in the bloclr and has one end thereof formed with an opening in which the guide 10 extends, the end of the spring engaging with the lugs 11 and normally tending to project the stud 9 outwardly from the block. r1`he 'spring 13 is preferably a flat spring bent in substantially U` shape as shown in the drawings; however, it may be found to advantage to use adifferent form of spring or means to eject the studs 9; Posts or rods 14 depend from the binder strip 6 and are f a thumb nut 17.

slidablyy received in the tubular guides-or y width as to receive the threaded rod 16 andr to provide shoulders against which the nuty 17 may bear. The'nut is formed with a reduced extension E to extend through the slot D, which acts as a guide for the nut. The pocket 18 is of such size as to permit access to the nut 17 for threading iton the rod 16. It is. obvious that as the nut is threaded onthe rod 16, compression is produced between the block 4 and the strip 6 in order to tightly compress or bind the edges of the loose leaves therebetween. A suitable ltorsion spring 19 is provided on vthe strip 6 for automatically moving `the rod 16 outwardly as shown in dotted lines of Fig. 3, when the nut 17 has been loosened sufliciently.y This spring consists of lengths of wire positivelyjconnected to the ends of the pivot piece C of the rod 16. These lengths of wire extend in a line with the axis of said pivot piece and have their free ends 2O laterally extended and imbedded in the strip 6 as clearly shown in Figure 4. When the rod 16 is moved to its binding position,

shown in full lines of Figure 1,. 2 and 3,

a torsional strain is produced in thewire sections, because of their peculiar formation and being imbedded in the strip 6,

which torsional strain will move the rod 16 to the dotted line shown in Figure 3 when the nut 7 is loosened.

The block 4 may be made of solid material mortised in a suitable manner shown or may vbe made of sheet metal.

From the above description it will be seen that any number' of vsheets from one` upward to the capacity of the book may be 'firmly bonnd therein, the capacity of the bool; being limited only by the length of the studs 9 and 14, their lengthv corresponding to thc thickness of the block 4. The block 4 and the back 2 of the book may be of the same thickness'in order to permit lthe book to lie flat upon a flat surface.

ln some forms of theinvention, it may be found desirable to omit the studs 9 and post 14, as the compression produced by the nut .i

17 between the block 4 and strip 6 is found sufficient to maintain the leaves firmly.. in position within the book. ln such a'modication, the leaves may be readily inserted orv removed at any place in the book. f

Having thus described the invention, it is to be understood that certain changes inthe construction, combination and arrangement of parts may bemade which fall within thev scope of the appended claims. j
