Wali'er 1?. Meier' lll imatentecl Mar.. 2.5, 1941 PATENT GFFICE BINDING CLIP Walterlt. Meier, Lincoln, Nebr. Application .lune 29, I1938, Serial No. 216,511 3 Claims. `(Cl. 281-25) My invention relates to clips for binding a plurality of individual leaves or signatures into book form, one of its objects beingthe provision of a clip which makes unnecessary the sewing ofthe book.

Another of my objects is the provision of a clip which may be applied tobind leaves or signatures into book form to maintain the individual leaves or signatures against slipping in any direction.

Another object which I have in View is the provision oi a clip which is adapted to pass through the individual leaves or signatures to hold them against shifting in directions parallel to each other, the clips having bendable means for holding the leaves or signatures in clamping relation.

Another of my objects is the provision of a binding clip of simple design, low cost of production, and of easy application without the necessity of using special tools, the clips being also adapted for use with special tools when the circumstances make it desirable or necessary.

Another of my objects is the provision of a binding clip which is especially well adapted to securing a tape when it is desired to provide the book with hinged covers.

Having in View these objects and others which will be pointed out in the following description, I will now refer to the drawing, in which Figure l is a view of the blank from which my clip is made, the view being in plan but slightly oblique to disclose thickness of the material.

Figure 2 is a similar view showing the iinished clip and ready for use.

Figure 3 is another similar view but showing the ears turned down at one end, the form as shown in Figure 3 being the most suitable for the application by hand of the binding clip.

Figure l is a view similar to Figures 1, 2, and 3 but showing the clip in the binding form.

Figure 5 is a sectional View showing the application of the clip for binding together a plurality of individual sheets of paper.

Figure 6 is a view in isometric projection showing the application of the clips for binding together a plurality of signatures, the use of the tape being also shown when it is desired to provide the book with hinged covers.

Figure 71's a View similar to Figure 5 but showing the use of the clip for providing round backs for the books.

Figure 8 is a sectional view showing the relation of the natures.

Theblank shown in Figure l includesV a body portion I il 4and two wings II on opposite sides of the body portion. The whole Adevice is cut out 5 of a single sheet of metal or similar material of rectangular form. The corners of the blank are cut away and notches are cut at the four corners of the body portion. This results in the blank having clamping ears I2 at opposite ends 10 of the body portion and similar `clamping ears I3 at opposite ends of the wings II. The clip is formed from this blank by bendingthe two wings II into convergent relation with ,each other as shown in Figure 2 `and as shown in section in 15 Figure 8.

VWhen the `device is the Figure2 form .it is in condition for application for the purpose of binding together a number of sheets or signatures into book form. When the clip is to be 2o applied by hand, the book should first be provided with saw cuts or other slits or kerfs as best shown in Figure 8. The angle of these cuts should be similar to that of the wings II. The entire clip may be then thrust through the saw 25 cuts so that the ears I2 and I3 project beyond the front and back leaves of the book. For hand insertion the Figure 3 form is preferable because it is possible to apply the pressure of the thumb to force the clip through the saw cuts. 30 If the clip is to be applied by means of a tool or machine without previously forming the saw cuts, the Figure 2 form will have certain advantages. In either case, the ears I2 and I3 are then bent down to completely clamping action.

The clips are generally formed of a length such that the body portion lil has a length which is substantially equal to the thickness of the book. Considerable latitude, however, is permitted since the ears I2 andlt may be forced down into 40 clamping relation with the book if the thickness of the book is somewhat greater than the length of the body portion I. As shown in Figure 6, the result is a slit which extends a slight distance inward along the back of the book. By 45 thus having an assortment` of clips of various sizes, it is possible to bind papers together of any desired thickness of the book with the leaves or signatures rigidly bound together in book form. 50

The preferred material is sheet steel because of its thinness and great strength. Ordinarily it extends across the back of the book to project slightly beyond the book because of the slight thickness of the material. In other Words, the

clips to the individual sheets or sigbook is very slightly wider at the clips than between the clips. This is ordinarily unobjectionable, but if it is necessary that the back of the book be continuous, it is only necessary to cut away a notched portion of the leaves or signatures at the back of the book to a thickness equal to that of the material of the clip as shown in Figure 8. Other materials having the requisite qualities may, of course, be used in the place of sheet steel.

When it is desired to provide the book With hinged covers, the clip is admirably adapted for the use of the tape commonly employed in securing hinged covers to books. The tape I4 passes underneath the clip as shown in Figures 6 and 7, leaving projecting portions which may' be secured to the covers of the books. .'Ihe clips may also be adapted for providing round backs as shown in Figure 7, it being only necessary to subject the clip to a second forming operation by bending them into curved form about the transverse axis. By accomplishing this bending operation through a conventional die stamping process, the body portion will flow sufliciently to prevent buckling of the wings Il. The back of the book Will then have the form shown in Figure '7.

Having thus described my invention in such full, clear, and exact terms that its construction and operation Will be readily understood by others skilled in the art to which it pertains, what I claim as new and desire to secure by Letters Patent of the United States is:

1. In combination, a plurality of leaves or signatures assembled in book form, the leaves or signatures being provided with angularly disposed registering slits projecting inwardly from the back edges thereof, a clip including a pair of angularly disposed wings seated in the slits of the leaves or signatures, a body portion connecting said Wings, clamping ears projecting from the extremities of said Wings and said body portion and bent down into clamping engagement against the front and rear surfaces of the book, and a tape passing through said clip and projecting beyond both extremities thereof, said tape being adapted for securing covers to the book.

2. A binding clip of bendable material having a body portion and a pair of integral wings projecting from the sides thereof in acute angular relation thereto, said body portion being adapted to be seated against the back of a book with said wings seated in kerfs at the back edge portion of the book, said body portion being cut away at the top and bottom adjacent each wing to provide ears on each end of said body portion and Wings adapted to be bent into clamping engagement with said book, and each of said ears on said body portion being of a trapezoidal shape corresponding to the area between said Wings to form a substantially continuous clamping surface with the ears of said Wings.

3. In combination; a plurality of leaves or signatures assembled in book form, the leaves or signatures being provided With angularly disposed registering slits projecting inwardly from the back edges thereof, a clip including a pair of angularly disposed wings seated in the slits oi the leaves or signatures, a body portion connecting said Wings, means associated with opposite ends of said clip for clamping said leaves or signatures together, and a tape passing through said clip and projecting beyond both extremities thereof, said tape being adapted for securing covers to the book.
