Patented Mar. 20, 1945 SHEET BINDING MEANS Frederick J. rent, sr., North Arlington, N. J. Application January 15, 1944, Serial No. 518,369

2 Claims. "((1281921) This invention relates to improvements in sheet binding means; andthe invention has reference,

more particularly, to a novel construction of binding' device especially useful for binding together the cover and loose inner leaves of sheet music. The invention has for an object to provide a novel binding device comprising a series of independent leaf embracing and holding elements, each longitudinally foldedupon itself to provide a tubular hinge barrel, said elements being longitudinally aligned, end to end, along a common hinge pin element, which extends throughth'eir hinge barrels, whereby outerand inner leaves or sheets may be'embraced by andsecured' between the sides of selected holding elements so as tobe' capable of being independently turned about the hinge p-in element, and yet securely connected or bound together against separation'one from another with risk of. loss or misplacement from their properly associated relationship.

The invention has for another object to'provide a binding device of the kind above referred to in which the leaf embracing and holding elements are made of rigidulous sheet material, such e. g. as thin sheet Celluloid or the-like, and in which the hinge pin element is made of a some what resilient material, such e. g. as textile or other cord which has been stiffened by a suitable sizingso as to be sufiiciently flexible without being flimsy, whereby the same is not easily subject to permanent distortion from a normal. straight condition; means to be provided in con nection with terminal members of the leaf embracing andholding elements for retainingthe hinge pin element against displacement fromoperative association with the, series of leaf embracing and holding elements served thereby.

Other objects of this invention. not at this time more particularly enumerated, will be understood fromv the following detailed description of the same.

An illustrative embodiment of the novel sheet binding means according to this invention is shown in the accompanying drawing, in which:

Fig. 1 is a front face view of a piece of sheet music the outer and inner leaves of which have been hingedly bound together by the novel-binding means of this invention; Fig. 2 is a fragmentary rear face view of the same; Fig. 3 is a fragmentary face view of the sheet music with its front cover leaf opened and its inner leaf exposed; Fig. 4 is a fragmentary face view of the opened sheet music showing its inner leaf turned; and

the terminal members of the leaf embracing and ment.

holding elements of the binding means, and the means provided in connection therewith for retaining thehinge pin element against displace- Similar characters of reference are employed in the herein above described views, to indicate corresponding parts.

Referring to the drawing, the illustrative embodiment of the sheet binding means is shown as and I1.

. Fig. 5 is a fragmentary perspective view showing operatively applied to a piece of sheet music comprising a front leaf or sheet I0, an inner leaf or sheet I l and a back leaf or sheet l2.

The sheet binding means comprises, in the i1- lustrative form thereof as shown, terminal leaf embracing and holding elements l5, and inter mediate" leaf embracing andholding elements l6 Each leaf embracing and holding element comprises a bifurcate structure formed by a tubular hinge barrel portion l8 and a pair of wing sections l9 extending therefrom. Each such embracing and holding element is made of rigidulous sheet material, such e. g. as thin sheet Celluloid or the like, which can beshaped and I set to provide the tubular hinge barrelportion l8.

Said leaf embracing and holding elements l5, l6 and I! are longitudinally aligned, end to end, upon and along a common hinge pin element 20. disposed to extend through their hinge barrel 1 portions I 8, whereby the leaf embracing and holding elements l5. l6 and, -l 1. may freely turn about said hinge pin element 20 as an axis. The hinge pin element 20is of somewhat less length than the totallength of the end to end aligned leaf embracing and holding elements, and to retain said hinge pin element against longitudinal dis placement from its operative assembled relation to said leaf embracing and holding elements, the outer ends of the barrel portions of the terminal leaf embracing and holding elements, are pinched and set together to provide a barrel passage closure portion 2|, by which the respective ends of the hinge pin element 20 is stopped so as to arrest longitudinal shifting displacement thereof.

The hinge pin element 20 is of rod-like form and is made of a somewhat resilient or springy non-metallic material. For example, the same may comprise a non-metallic cord or rod of inherently resilient material, or a textile cord which has been stiffened by a suitable sizing substance so as. to be sufficiently flexible without being flimsy. A resilient cord or rod of such characteristic is desirable so that it may flex without being subject to permanent bending or distortion from its normal straight condition, and consequently is not subject to risk of bending out of shape so sheet music to be bound are separated, whereupon f said front sheet ill is inserted between the wing sections IQ of the respective terminal leaf embracing and holding elements l5, and the inner faces of said wing sections are adhered by a suitable adhesive to said front sheet Ill. The back sheet I2 is then inserted between the wing sec'-" tions IQ of the respective leaf embracing-and holding elements It next adjacent to the terminal elements !5, and the inner faces of said wing sections are likewise adhered by a suitable adhesive to said back sheet [2. Finally the intermediateor inner sheet H is inserted between the wing sections IQ of the middle or-remaining leafembracing and holding element H, and, in like manner said wing sections are adhered by a suitable adhesive to said inner sheet H.

The adhesive employed to secure the music sheets to and between the wings IQ of the holding elements may be applied at the time of carrying out the binding operation,cr,'if desired, the inner faces of said wings 19 may be provided with a dry adhesive coating ,22 (see-Fig. '5) which can be eral leaves or pages may be easily, freely and independently turned about a common hinge axis. The hinge pin element being resilient, will not take a permanent bend so as to either distort the plane of the leaves or pages, or obstruct the free swinging turning thereof, and yet, since the hinge pin element extends substantially throughout the length of the sheet music, the latter cannot be accidentally folded or crumpled transversely, and consequently is kept in good condition and its useful period of life is therefore substantially prolonged.

I am aware that some changes could be made in the above described constructions without departing from the scope of this invention as delined by the following claims. It is therefore intended that all matter contained in the foremoistened for use at the time of performance of the binding operation.

Although the double wing form of the holding elements shown and described is preferable, it

will be understood that one of the Wings may beomitted if desired and but a single wing provided for adherence to the leaves or sheets to be bound. It will also be understood that the order in which the holding elements are adhered to the successive leaves'or sheets to be bound may be varied from that above described as may be deemed most expedient to the user of the binding device; furthermore, it will also be clear that the number and length sizes of the holding elements may also be varied within reasonable limits, and

according to the total number of leaves or sheets to be accommodated. For the ordinary three leaf form of sheet music the described number and relative arrangement, of holding elements will probably be found the most satisfactory.

The novel binding means according to this ingoing description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense,

I claim 1. Sheet binding means comprising a series of independent leaf holding elements arranged end to end, each holding element being formed from rigidulous sheet material to provide a longitudiholding elements hinged thereon.

All

2. Sheet binding means comprising a series of independent leaf holding elements arranged end to end, each holding element comprising a body of sheet material having a longitudinal tubular hinge barrel integral therewith, interior marginal portions of successive leaves to be bound being secured to the bodies of selected holding elements, a hinge pin element of resilient material common to and extending through aligned hinge barrels of the holding elementswhereby the latter may turn independently thereon, and the terminally disposed holding elements having means to close outer end portions of their hing'e barrels against longitudinal displacement of the hinge pin element relative to the series of holding elements hinged thereon.
