Description
April 1935. R, w. BERGMANN 1,999,829
BINDER Filed Aug 1, 1934 INVE TQR BY MM Ola/6* Wm ATTORNEYS Patented Apr. 30, 1935 UNITED STATES PATENT OFFICE Application August 1,
3 Claims.
united by a spiral, the convolutions of which pass through perforations at the inner edge of the leaves.
To these and other ends my invention consists in further arrangements of parts whereby the cover may be completed as a unit and the assembled book leaves readily attached thereto all as will be more fully described in the following specification, the novel features being pointed out particularly in the appended claims.
In the drawing:
Fig. 1 is a perspective view of a completed book constructed in accordance with my invention, the book being shown with one of the covers in open position.
Fig. 2 is an end view.
Fig. 3 is a longitudinal sectional the line S -3 of Fig. 1.
Fig. 4 is a detail perspective view of the back plate.
Fig. 5 is a fragmentary view partly in section illustrating a modification of said plate.
Similar reference numerals in the several figures indicate similar parts.
Book pads comprising a plurality of sheets, which may be blank pages or pages containing printed matter, may be conveniently united by threading a wire spiral through a series of perforations at their inner edges. With such a fastening it is customary to place the perforations in the leaves as close together as practical and to use a spiral of the required diameter with its convolutions spaced according to the distance between adjacent perforations. It will be seen therefore that with a group of sheets'or book pages a and a spiral b they may be bound together by starting the leading end of the spiral in the first perforation and rotating it until it has been threaded through the perforations.
The above is a very satisfactory way of securing a number of sheets of paper together but it has the disadvantage that it does not lend itself readily to the attachment of a suitable cover to the book pad without which the leaves bend readily in all directions, the spiral also being flexible.
In carrying out my invention, to overcome the above mentioned disadvantages, I provide a b'inder comprising either stiff or flexible covers c and d hinged at opposite edges of a book portion 0,

or backbone as it is sometimes called, which is of width appropriate to the diameter of the associated spiral. On the inner face of the back e, I mount a thin fiat or concave plate 1 which may be secured as by rivets, indicated by 9 (Fig. 3), by a plurality of cars h (Fig. 5), formed integrally with the plate, or merely by the overlaid binding 2' glued or cemented on the inner faces of the back and adjacent edges of the covers. Means for uniting the spiral to the plate 1 is provided by in furnishing thereon a plurality of securing members. These are preferably formed by striking ears 9 (Fig. 4.) from the metal itself at points suitably spaced to register with certain of the convolutions of the spiral and engage the same when bent downwardly in the form of a loop. In practice I provide one such projection near each end of the plate and any desired number of such intermediate clipping pieces may be used.
The advantage obtained from this novel ar rangement of the parts is that the book pad and cover portions may each be assembled independently and when desired interconnected by merely interlocking the convolutions of the spiral with the corresponding projections which are bent snugly over the contacting point of the spiral.
What is claimed is:
1. The combination with a spiral for threading through the perforated edges of bookleaves, of a back plate for attachment to a book cover having thereon a plurality of spaced ears struck up from the plate and capable of being bent over to embrace separate convolutions of the spiral.
2 The combination with a spiral for threading through the perforated edges of book leaves, of a back plate for attachment to the back portion of a book cover composed of a strip of thin metal having ears formed by striking up portions of the metal and capable of being bent over to embrace separate convolutions of the spiral'at separated 40 points throughout its length.
3. In a book binding in which the book leaves are united at their inner edges by a spiral the convolutions of which pass through perforations in the leaves, the combination with a back portion and cover portion thereon, of a securing plate having ears extending in opposite directions from the two sides of the plate, one set of ears being adapted to pierce said back portions to fasten the plate thereto and the other set of ears being adapted to be bent over in engagement with convolutions of the spiral.
