4 Claims. 1

This invention relates to boolrbinclings of the so-called spiral type, wherein a plurality of leaves is maintained together by a helical or spiral coil. It is an object of the invention to provide improved means by which such a 0011 can be effectively secured in place within the book covering.

It is another object of the invention to provide an improved bookbinding, having its parts arranged for quick and simple assemblage by the purchaser or user, so that the article can be delivered in flattened, knock-down or dis-assembled condition to not only facilitate shipping but to result in'a saving of assembling cost to the manufacturer.

It is another object of the invention'to provide .a bookbinding of this character in which the parts may be readily fabricated from sheet metal, which parts can be easily fitted together in assembled relationship by the purchaser or user, and when assembled, the binding will be strong and sturdy and efiectively hold the leaves of the book in proper relationship.

It is still another object of the invention to provide an improved assembly method for parts of a bookbinding, enabling said parts to be assembled in operative relationship with a minimum of effort and by the use of a simple hand tool to provide a book binding of strength and satisfaction.

In the accompanying drawings, wherein an illustrative embodiment of the invention is disclosed, Fig. 1 is a perspective view of the bookbinding, showing the leaves and the spiral which connects the same separated from the mounting means;

Fig. 2 is a perspective view of the mounting strip and the end when assembled, provide the mounting means for the leaf -car.rying spiral;

Fig. 3 is a longitudinal sectional view through the back or binding of the book, showing the base plate secured thereto;

Fig. 4 is a sectional view, taken substantially on the line 44 of Fig. 1, looking in the direction of the arrows; and

Fig. 5 is a sectional view, taken substantially on the line 5-5 of Fig. 4, looking in the direction of the arrows.

Referring to the drawings, I and 2 indicate the respective covers 01' a book to which the improved binding is applied. The covers I and 2 may be of conventional form and are connected by the curved back panel 3, which may consist of an outer covering 4 of cloth, and an inner lining strip 5, also or cloth, with a suitable reinforcing or stiffening material, such as cardboard B, interposed between the outer covering; and liningstrip.

Located under and concealed by the lining strip 5is a stiff backing plat 1 preferably of thin metal.

the base plate, plates which,

then elevating the. tongues 8 to the vertical posi- This strip in its initial form, is flat as other. simple tool with two stamped-out tongues 8. located-adjacent to the opposite ends of the strip. Normally tongues lie down flatly, as shown in Fig; 3; pro- 'jecting just sufliciently to. enable them to be engaged and bent upwardly. These tongues are exposed on the outside of the lining strip 5 so that they may be engaged with the spiral-engaging member or mounting strip I30 to-zbeidescribed, as well as with end members 11 The spiral-engagingmember :or mounting strip l0, shown most clearly in Fig. '2, is an elongated metallic strip having its opposite ends :intumed or bent into hook-shaped formation as indicated at 12 and I3. The mounting stripto is. alsorprovided adjacent to these hook-shaped ends. with apertures or slots M of a shape and size to permit of the passage of the tongues 8 through them. The mounting strip in is also slit inwardlyrrom its opposite longitudinalledges l5 and litoiprovi'de a plurality of upstanding, spaced lugs l1 and t8 which fit between the convolutionsor the spiral bindingzdto hold the same in the required spaced relationship and prevent endwise or longitudinal compression of the spiral binding memher.

The end members H for the bindingeach consists of a diskshaped end wall I9 from which'an integral channel-shaped strip LN extends at sub.- stantially right angles. This channel-shaped strip 20 is of a width to-enable the end portions of the spiral-retaining strip Hi to be received within it, with said end portions or the strip H! being embraced between the side walls-2| :and' 22 of the channel strip. Provided in thebcttom of the channel strip 20 is a slot or aperture 28 of a shape and size to permit of the passage of one of the tongues 8 through it.

The spiral or helix 28 is of the conventional wire type and receives and holds the leaves 24 in the conventional manner.

When the book is delivered, it may be in disassembled condition but ready for quick and simple assembly by therecipient. The book may be delivered with the base plate 1 secured in place in the back of the book but in its flattened form, thereby permitting the shipment of the book covers in perfectly fiatcondition. While thebook covers are fiat, the tongues thereof are .bent downwardly as shown in Fig. 3. Thexnrstl step in the assembly of the book consists i curving the back of the book :and plate I transversely and tion asshownin Fig. 2. The'curving of theplate can be done bya press and raising of ithetonsuas canbe done by the insertio of a .knn 'blad -or under each tongue and bending the tongue upwardly to vertical position,

vention, it

When the tongues 8 have been so raised, the

bers ll fitted on its opposite ends, the channel strip 20 being slipped under the end of the strip;

until the apertures 23 in the channel strips .2 are in alignment with the slots i i in the strip iii. Now, the strip III, with the end members i fitted in place as just described, is placed in the back of the book in position to cause the tongues 8 to project upwardly through the aligned apertures. I4 and 23. When the parts have been positioned as above described, the tongues 8 are then bent over or clenched as clearly seen in Fig. 1 and they will then serve to attach the mounting strip Ill as well as both of the end members ii to the base plate I which was previously secured in the back of the book between the outer fabric t and inner fabric 5. All that now remains to complete the assembly of the binding is to connect the. spiral or helix 28 to the mounting strip l9 and this is done by inserting the inturned hooks i2 and I3 within a few of the convolutions of the spiral at its opposite ends to thereby engage the hooks with such convolutions, as clearly shown in Fig. 4 and confine the spiral or helix between the end plates I9 of the two end members H.

The lugs i1, extending upwardly from the mounting strip 19 will enter between the convolutions of the spiral 28 and will hold the same in properly spaced relationship and prevent endwise shifting or compacting of the helix.

Since the several parts of the binding, namely, the base plate I, the mounting strip 19 and the end-members II are held together solely by the engagement with the tongues 8, formed as integral parts of the base strip 1, it will be apparent that the assembly of these parts into a sturdy binding structure is easy, and may be effected without special tools or skill. Hence, the book and its component parts may be sold or delivered with its parts in separated relationship if desired, leaving the assemblage to the purchaser or user of the book. On the other hand, if it is desired to deliver the book in fully assembled condition, this can be readily done without requiring any substantial manufacturing expense since the assembling time required is short indeed.

Having described one embodiment of the inis obvious that the same is not to be restricted thereto, but is broad enough to cover all structures coming within the scope of the annexed claims.
