This invention relates to loose leaf binders and has for its object an improved loose leaf binder of minimum simplicity and economy of manufacture.
5 In loose leafbinders, especially those intended for the school trade, a very small saving in the cost of the binder without impairing the function of the elements, constitutes quite a material advance in the art from the standpoint of promoting sales and meeting the competition of other binders. In the early days of the toggle arm type of binder, it was customary to provide both a bottom and top shell. Later as the demands of cheapness required simplifying the manufacture, the bottom shell was done away with. This introduced somewhat of a prcbiem in properly fastening the remaining top shell to the book cover. Various methods have been suggested in the prior art but it is believed that our improved arrangement has all the economy of previous arrangements and produces a better and more effective article. This will be more fully explained hereinafter.
In the drawing:
Fig. l is a longitudinal cross section of a binder but partly in elevation.
Fig. 2 is a plan View of the shell of the binder.
Fig. 3 is an inverted plan view of the same.
Fig. 4 is an end elevation of the binder.
Fig. 5 is a section taken on the line 5-5 of Fig. 1.
The usual shell or having turned over edges a is employed to house and the turned over edges to journal the wires b which meet in the usual toggles and are provided with half eyes 0 at each end and intermediate half eyes e. The ends of the shell are provided with transversely curved tabs d adapted to be turned in under as shown in Figs. 1 and 3 to provide the fastening or" the g shell to the binder back ,1. These members d may be in the nature of pads for lying against the binder back. I provide these tabs with notches g which provide a weakened portion 7a which will insure the easy and accurate folding of the tab. It is desirable to get an accurate folding to bring the perforations k and m into substantial registry when the tab is folded in place so that the long shank rivet n can be passed up through an opening in the binder back, the opening in the tab, and the opening m in the top of the shell. The end 0 of the rivet is then turned over slightly so as to bind the shell tightly to the back.
I preferably make the hole through the tab of larger diameter than the hole through the shell to give liberal tolerance in fitting the parts together.
It will be noticed that the tab is curved transversely. This gives it more strength to resist the pull of the long rivet. The tab sides also overlap (see Figs. 3 and 5) the turned over edges of the shell and hence the whole tab is strengthened to resist the pull of the long rivet.
This type of fastening is very effective and very desirable in the new type of binder backs that are concave as shown in Fig. 5. This is now 5 the prevailing type and the fastening very nicely adapts itself to this type.
I claim:
1. In combination with the back member of a loose leaf binder which is adapted to hingedly connect front and back cover members, a shell member constructed to pivotally support openable eye members for holding loose leaves, the shell having endportions which are doubled back upon the shell member, parts connecting the end portions the body of the shell, said parts being disposed substantially perpendicular to the back, said end portions each having an aperture therein located relatively close to the corresponding connecting part and the body of the shell 0 having apertures in substantial alignment with the apertures in said portions, said portions being adapted to be positioned flush against the back member of the binder, and rivets passing through the back member of the binder and the 5 aligned apertures and having ends riveted over to hold the shell to the binder back, the body of the shell, the said end portions and connecting parts resisting the collapsing force of the rivets whereby the back member is relieved of such. g force.
2. In combination with the back member of a loose leaf binder, a shell member having edge portions positioned to pivotally support openable eye members for holding loose leaves, said shell member being adapted to be disposed upon the back member with the body of the shell member spaced therefrom, the body of the shell member having an aperture near each end, a pad like member near each end of the shell positioned ioo flush against the said back member, means disposed substantially perpendicular to the back for holding the pad members in spaced relation with respect to the body of the shell, said pad members each having an aperture therein substantiallyw ozi aligned with the adjacent aperture in the shell and the aligned apertures being relatively close to said perpendicular holding means, and rivets passing through the aligned apertures and through the back member for holding the Shellassembled to the back member, said means which holds the shell in spaced relation with the pad members being adapted to take compression forces exerted by the rivets, whereby the back member is relieved of such force.
3. In combination with the back member of a loose leaf binder, a single strip of metal having its longitudinal edges disposed at an angle to the body of the strip and arranged to pivotally support openable eye members for holding loose;
leaves, an extension on each end of the strip of metal, said extensions being fashioned through substantially 180 to provide tab portions at the ends of the strip disposed in spaced relation with respect to the body of the strip of material, and parts connecting the body of the strip and tabs and which are-disposed substantially perpendicular to the back member, said tabs adapted to rest flush against the back of the binder, the tab portions and the body of the strip having substantially aligned apertures adjacent the said parts, and rivets passing through the back member and apertures in the tab portions and strip, the body of the strip and the tab portions and their connecting parts taking the compression force of the rivets, whereby the back member of the binder is relieved of such force.
4. In combination with the back member of a loose leaf binder, a single strip of metal having its longitudinal edges disposed at an angle to the body of the strip and arranged to pivotally sup port openable eye members for holding loose leaves, an extension on each end of the strip of metal, said extensions being fashioned through substantially 180 to provide tab portions at the ends of the strip disposed in spaced relation with respect to the body of the strip of material and for resting flush against the back of the binder, parts positioned substantially perpendicular to the back and connecting the tab portions and body of the strip and adapted to take compression forces, the tab portions each having an aperture and the body of the strip having an aperture near each end, each substantially aligned with an aperture in a tab, and rivets passing through the back member and apertures in the tab portions and strip, the tab portions overlying the edge portions of the strip of material whereby they are rigidly held spaced from the body of the strip to take the compression force of the rivets.
5. The combination with the back member of a loose leaf binder which is adapted to connect front and back cover members of the binder, a single piece shell comprising a strip of sheet metal having its edges fashioned angularly as regards the body of the shell for pivotally supporting openable rings for holding loose leaves, said shell presenting a concavity and placed against the back member of the binder with its concavity facing the back member, a relatively short extension at each end of the shell, the portions of the extensions next adjacent the body of the shell being turned over to a position substantially at right angles to the body of the shell, the extreme ends of the extensions being turned over at substantially right angles to the first mentioned portions of the extensions so as to substantially parallel the body of the shell, said extreme end portions of the extensions lying flush against the back member of the binder and said extreme end portions being spaced from the body of the shell a distance substantially equal to the height of the first mentioned portions of the extensions,
rid said first mentioned portions being adapted to take compression strains, the extreme end portions each having an aperture therein, the body"- of the shell having an aperture near each end, said apertures being in alignment with the apertures in the extensions, and long shank rivets passing through t -e apertures in the body of the shell and extensions and through the back mem- '110 ber of the binder.
