BINDING CASE FOR HoLDINe SHEET MUSIC'AND THE LIKE.

Application filedvoctober 12, 1921. Serial No. somes;

T all whom it may concern I Be it known that I, J oHN WILLIAM WEST, of 9 Bushey Hill Road Peckham Road, Camberwell, London, 5, England, a British subject, have invented certainnew and useful'lmprovements in Binding Cases for Holding Sheet Musicand the like, of

which the "following is a specification.

' This invention relates to binding-cases, 10 for holding sheet music andother doubleleaf papers, of the kind" having a rigid backmember including what is hereinafter referred to as the string bar, whereof the front surface of the string-bar, beingstretched over thestraining-bridges whereby said binding strings are spaced apart from one another and from the string-bar so as to be each adapted to receive beneath it the back-fold of a double-leaf sheet of paper comprising four pages or any mul tiple thereof. i

The primary object of the present invention is to provide an improved binding-case of the kind-referred to,'so constructed as to allow any selected paper contained therein to lie fiat, without tendency to curlupwards, when the binding-case is laid open so as to expose the particular paper selected;

The invention will be described with reference'to the accompanying drawings where in Figure 1, is an inside face (view of the binding-case, portions being broken out;

Figure 2 is a transverse section on line- 22 of Figure 1, drawn to a larger scale; Figure 0 3 is a sideelevation, partly in section, of the string-bar, shewn separatelyto a smaller scale; Figure 4 is a perspective view of one end ofthe back-'barwith theterminal block attachedthereto Figure 5 is-a perspective n each edge of the str ng-bar to accommodate view of one ofthe "terminal blocks; 'Fig ure 6 is'an end 'view of the string-bar shewing the attachment of the strings; and FigurevTis-a section online 7 7 of Figure 2,

drawn to a largerscale.

n :The improved binding-case, as seen in the example illustrated, com rises the usual pair of fiat-boards 1,0 orming the rigid outer covers of the binding-case, these boards strip?) of leather'or other strong and flexible material whereof the respectivei marginsrarecemented at c, c to the outerrear marg ns of the boardsa, a (as by paste) so as to leavebetween the rearedgeso-f the-t latter a centralunattached width. of the hinge-strip Z) corresponding-to but greater being held together at the rear by, a hingea than the distance between the boards a, a

when the binding-case is closed by folding said boards together. A half-round bar (I of rigid material, preferably wood, hereinafter termed the back-bar, is cemented (as by glue) tothe central unattached portion ofthe width of the hinge-strip h, the

hal-feround' surface of this back-bar d be ing towards t-he' rear so asto contact'with,v "the hinge-strip Z), whilst the fiat inner surface of the1bar d extends'substantially in ,the'common plane ofthe' outer surfaces of the boards. a, a when thebinding-case is p laid fully open. ;For the sake, of greater securitya" strip'cl of linen or other strong and flexible material is cemented (as by glue orpaste) to the flat inner surface of the baclcbar cl, and also Ito the edges and rearmargins of the boardsa, was at f,;", the margins of the strip a beingpreferably afterwards concealed for the most part by the usual lining g of paper pasted over the inner surface of each board a, a. v g A half-round .bar 71/ of rigid m'aterlal, preferably wood,"i hereinafter termed the string-ban, is secured (as by glue supple- -mented if desired by nails as'at '4') to the central portion of the width of the stripe where thelatter contacts withthe backbar d, the half-round surface ofthis string-bar being towards the front whilst its width is less than that-of the back-barbyan amount corresponding with or slightly greater than TthQJCOTlJOlIlh thicknesses of the two boards a, men that sutiicientspace is left'beyond the corresponding board a wheuthe latter is straining-bridge y, consisting preferably. 0f

a; rectangular strip of leather, which embraces the angular width of the half-round surface and is of such thickness as to up stand therefrom to a height corresponding approximately to the thickness of the folded sheets of paper which are to be held in the binding-case; whilst over this bridge are stretched side-by-side a number of strings 7c corresponding in number to the number of such folded sheets which the bindingcase is adapted to accommodate.

It is usually more convenient to stretch the strings 76 upon the string-bar h before -one edge thereof and parallel to the axis ofthe bar, thence over the bridge 7' at the farther end, and round the adjacent pin m; the string being wound or passed in this manner to-and-fro lengthwise of the stringbar as often as required in order to provide the desired number of individual strings 70, which are tightly stretched close beside and parallel to one another. The use of leather for the bridgefj ensures the strings 7c biting into the bridge and prevents them from slipping over' one another; if a material harder than leather is used, the bridge may he formed with shallow notches to retain the individual strings in place. After the free end of the whole length of string has been made fast, the projecting end portion of each pin m is bent over upon the convolutions of string lapped around the pin so that whilstthe in no longer projects beyond the extremity of the string-bar h, the strings, are firmly clamped. to the pin m itself' where they pass around it.

The back-bar 0 and string-bar 71 are of equal length, whilst the boards a, a and "bagcki'ng strip b are of such depth as to extend distance of (say) about half an inch. more or'less, beyond each end of the back bar and string-bar; the terminal space thus at each end being occupied by a block ng preferablyot wood secured to the backbard by a, nail 0 (supplemented by glue if desired) so as to cover the extremities of thegbars d and h and form a finish to the article, Each blocks is of; substantially oval: shape so as to conform to. the halfround contour of the back-bar d, and has at its inner side a projecting portion 39 of r creases a adaphdi fit e a est hebrid eifi Inns o y the sp gs k lying thereon,

On inspection of Figure 2 it will. be readily appreciated that, when the bindingcase is laid open on a table or other support, the back-bar cl, owing to its half-round contour, can roll overlatera'lly in either direction so far as may be necessary to enable any selected paper amongst the contents of the. binding-(res? t be exposed in the fiat without tendency to curl upwardsv Experience shows that. this. feature, which is novel, is of the utmost practical value; the absence of the half-round back-bar having for effect to prevent any of the papers, ex cept at most a very few of those in theiniddie of the collection, from lying open hat. The importance of the :t'e'aturerin question will thus be obvious in the case, for eXample,

of sheet-music.

Again, it will be seen from. Figure 7 that the inwardly-projecting portion 79 of each terminal block n, by reason Of'its overlapping the adjacent straining bridge 7', is

adapted to co-0perate therewith in preventing, more. effectually than have, the constructions hitherto proposed, injury to the papers held in the binding-case, owing to such papers tending to slip lengthwise of the binding-strings 70 to a distance beyond" the strainingbridge and thus to become torn or split along their back-folds.
