` 3 claims. (ci. 12e-24) This invention relates to the `manufacture of casings for loose leaf bindersand the like, and has particularreference to the construction of back panel members for the casings of such binders.
, A customary way of forming these casings is to assemble in iiatforrn a narrow strip of suitable back forming material such as cardboard, which isvto form the backV of the binder, flank-ed by wider panels of cardboardwhich are to form the sides ofthe binder. Thesepanels are then covered and connected by the usual cover hinge and lining sheets and alloose leaf m-echanism is then riveted to the insideof the back panel. The use of metal to reenforce the back panel has complicated the riveting operation and in my Patent No. 1,983,883, dated December 11, 1934, I have disclosed and claimed an arrangement of parts and manner of construction Which overcomes the difficulties in the riveting operation.
In my prior arrangement and method the heads of the rivets appear on the outside unless a relatively expensive outside back member is used.
One object of my present invention is to provide means for attaching rivets to a back panel of the general type shown in the above mentioned patent in a manner such that the rivet heads are concealed from the outside of the binder, and to accomplish this without hindrance to the automatic machine operation by which the cover,
hinge, and lining strips are usually applied.
The invention has a further application to out- Y side back panels of the type shown in my copending application Serial No. 758,756, led De cember 22, 1934.
Other and further objects will be apparent from the following specication and claims.
In the accompanying drawing,
Fig. 1 is a plan view showing the end portions 40 of a back panel embodying one form of the invention;
Fig. 2 is a sectionsubstantially on line 2-2 of Fig. 1;
Fig. 3 is a plan view of one end of a back panel 45 as shown in Fig. 1 but before the rivet is put in place;
Figs. 4 and 5 are fragmentary plan views showing two ways of inserting the rivets after the casing has been formed; and
50 Fig. 6 is a transverse sectional view of the central portion of a casing with a loose leaf mechanism in place.
In the drawing the thickness of parts has been exaggerated where desirable to better show the 55 structure.
Referring to the drawing, the back panel is shown as formed of a strip l of cardboard, leather, or .other backing material reenfcrced and stiffened by the addition of a sheet of thin metal 2 extending across one face of the cardboard strip 5 and having its longitudinal edges bent around the longitudinal edges of the strip l and onto its opposite face, as indicated at 3, to firmly hold the cardboard and metal members together. The metal and cardboard members may be secured tO- 10 gether in any other suitable manner, as the specic Way in which the metal and cardboard portions of the back panel are assembled doesA not form a part of the present invention. According to my present invention, prior to the 15 application of the metal sheet to the cardboard strip, I form in the metal at the points where it is desired that the rivets be located, a generally T shaped opening 5 and press the metal adjacent the stem portion 6 of the T opening 5 outwardly, 20 as shown at l, a distance from the plane of the body of the metal substantially equal to the thickness of the head 8 of the rivet 9. As best shown in Fig. 2, when the metal sheet and strip I are assembled, the struck-up portion 'l forms a recess 25 or pocket i9, the inner wall of which is formed by the cardboard strip. The wi-dth of the pocket IG is made substantially equal to the diameter of the rivet head, the length being somewhat greater and the stem portion 6 of the T shaped opening 30 5 is of a width to just freely receive the shank Il of the rivet. As previously stated, the portion 1 is struck up a distance to approximately equal the thickness of the head of the rivet and preferably this approximation is very slightly less thanY the head thickness, so that the rivet head makes a tight, crowded fit between the up-struck metal portion and the relatively yielding cardboard of the strip. It will be understood that the exact form of the pocket may be varied from that shown. 40
The back member, as shown in Fig. 3, may be assembled in that form with suitable side panels l5, see Fig. 6, and the usual cov-er, hinge and lining sheets indicated at l5, Il, and I8, respectively, and the casing completed in a conventional automatic case forming machine. When the casing comes from the machine the rivet receiving pockets are covered by the hinge Sheet I1, as shown in Fig. 4, and the pockets may be opened to receive the rivets by cutting T shaped slits over the T shaped opening 5, as shown in Fig. 4 at I9, or by completely removing the portion of the hinge sheet which overlies the struck-up portion 1, as shown at 2E) in Fig. 5, or in any other suitable way.
At any suitable stage in the manufacture of the casing the back panel may be curved to rounded book back shape, as shown in Fig. 6, where the curved instead of the iiat back form is desired. As shown in the latter figure, after the casing is completed and the rivets inserted in the retaining pockets IEB, any lsuitable form of leaf retaining mechanism, such as 2| indicating a ring mechanism, is secured in the casing by means of the rivets 9, thus completing the binder.
While I have illustrated a form of back panel in which the metal sheet in which the pockets I0 are formed is substantially coextensive with the cardboard strip l, it will be understood that my invention is applicable to other forms in which a less area of the strip is embraced or covered by the metal, the minimum essential being a suicient area ofA metal to form the pocket and provide for its attachment to the cardboard strip.
It will also be appreciated that the invention may be advantageously used for securing rivets to decorative back panels, such as are shown in my copending application Serial Nos. 758,756, and,758,757, led December 22, 1934 an-d December 22, 1934, respectively.
I claim: Y
1. A back panel member for use in the manufacture of loose leaf binders and the like which comprises a strip of backing material having a piece of thinvmetal secured thereto, portions of said metal being bent outwardly to form an openended pocket-like recess between the metal and said strip at each end portion of the back panel member, said bent-out portions of the metal member being each provided with a slot in which the shank of a rivet for permanently securing loose leaf mechanism to the back panel member engages when the head of such rivet is inserted Vin the recess, the openrends of said recesses confronting eachother across the center of the panel.
2. A loose leaf binder having a back panel provided with a plurality of pockets each having an opening onto the inside only of the back panel to permit the passage of the shank of a rivet, and a lateral opening also on the inside of the back panel to -permit the entrance of the'head of the rivet, rivets/received in said pockets, and a loose leaf structuresecured to the shanks of the rivets, the lateral openings of the pockets being arranged at such an angle relative to each other that the engagement of therivets with the loose leaf structure prevents their disengagement from the pockets. V Y 3; A loose leaf binder having a back panel provided with a plurality of pockets each havingV an opening onto the inside only of the back panel to permit the entrance of the'shank of a rivet, and a lateral opening also on the inside of the back panel to permit the entrance of the head of the rivet, rivets received in said pockets, and a loose leaf structure secured to the shanks of the rivets,
the lateral openings of the pockets beingarranged
