10 Claims.

This invention relates to an adjustable ring-' book and more particularly to metal parts therefor.

An object of the invention is to provide a ringbook in which two or three or more rings may be adjustably secured and in which the operation of the ring sections is facilitated by booster levers. A further object is to provide a metal back strip equipped with rods or wires to which ring sections are adjustably secured, the ring sections being provided with improved interlocking connections. Other specific objects and advantages will appear as the specification proceeds.

The invention is illustrated, in a preferred embodiment, by the accompanying drawing, in

which- Figure .1 is a top plan view of metal parts for a loose-leaf book embodying our invention; Fig. 2, a'bottom plan view; Fig. 3, an enlarged detail sectional view, the section being taken as indicated at line 3 of Fig. 1; Fig. 4. a view similar to.

Fig. 3, but showing the ring sections open; Fig. 5, a detail sectional view, the section being taken as indicated at line 5 of Fig. 1; Fig. 6, a broken plan detail view ofa pair of ring sections spaced apart to show their inner connecting ends; Fig. 7, a sectional view of a mo'difiedform of construction illustrating an initial step for securing a ring section to "a wire; and Fig. 8, a similar view showing the connecting operation completed.

In the illustration, I0 designates a metal back strip provided with inturned spring side walls I I. The back strip III is provided with openings I2 through which the ring sections I3 extend.

Housed between the spring side walls II are the rods or wires I4 which are identical in con struction. In theillustration given, each of the wires '14 is provided with in-bends l5 at three points, to which in-bends are secured the ring sections I3. One end of each wire I4' terminates near the end of the back strip II], but the other end is extended through an'opening I6 in the end wall [1 of back strip I ll and is then turned at right angles to provide a booster lever I8. Preferably, the end of the wire is flattened to provide a thumb piece'IS which, if desired,'may be provided with knurling or superficial roughening '20.

Anysuitable means for securing the in-bends I5 to the ring sections I3 may be employed. I prefer, however, to swage' the in-bends I5 to jprovide flanges 2 'I which are received within the T-slots 22 of the ring sections I3. It will be observed from the showing in Fig. 6 that the flanges ZI taper'near their ends inwardly toward the body of the wire and thistaper facilitates the threading of the flanges 2| withinthe -T- slots 22 of the ring sections I3. The flanges 2I and T-slots 22 are so formedthat when the flanges are drawn within, the slots, the parts become firmly locked in the position shown in Fig. 6. However, if it is desired to remove the ring sec: tion 13 from engagement with the bend I5, this may be done by sliding the ring section later:- allyt On the other hand, if it is desired tojforr'n a permanent connection, the wirebend ,l5 may be tapped to expand .themetal within the T slot to form a permanent interlock. It will be understoodthat instead of employing a T-slot and corresponding flange, that a dovetail con struction. maybe employed. If desired, the ring section I3 may be sheared or flattened onone side to provide a straight face 23,.as shown in Figs. 7 and. 8, the straight facebeing. adapted to lie against the bottom of a recess 24 with which the in-bend I5 is provided. Theadjacent metal 25 of the wire bend I5is then spun. about the ring section I3 to form the interlock, as shown in Fig. 8. It will be understood thatwhile we have shown several methods of connecting the ring sections to the. wire bends I5,-many other suitable methods maybensed. ,j N u M The ring. sections I3 are provided attheir inner ends with suitable interlockingconnections. We prefer that each ring section shallbe a .duplicate of the other and that the interlocking ends be identical, in construction. As shown more clearly in Figs. 3, 4 and 6, the lower face of each interlocking end is bevelled as indicated by the numeral 26 while the upper face of each end is provided with a shoulder projection 21., ,Adjacent each shoulder 21 is arearwardly, inclined bevel 28. When the two ends are bro ght to: gether, as illustrated more clearly in Figs, 3 and 4, it will be observed that the two endsmeet along a line which is formed by the two

beveled surfaces

26 and 28, and that the interlocking shoulders 21 maintain the ends against lateral movement. In order to bring the shoulders 21 against each other and to maintain them in this position, we have formed the inner faces of theends with about a 5 taper, as shown more clearly in 6. This slight taper of the inner contacting. faces causes the locking shoulders to remain in contact.

While we have described a particular form of interlocking end foreach ring section I3 which has the advantage ofcausingthe ring sections to oscillate about a single line point, thus reducing the frictional surface between two engaging ring sections, it willbeunderstoodthat other types of hinge connections may be employed in combinathe prior art. a We claim:

tion with other features of our invention.

In order to lock the free end portions of the wires firmly against the spring walls H, and in order to adapt the metal back strip to a round back notebook, we provide the reinforcing strips or buttons 29, as shown more clearly in Figs. 2 and 5. The member 29 comprises a rounded web portion 30 which is adapted to be placed against the rounded back of the cover, and which is provided centrally with an opening 3| through which the rivet or other fastening means may be extended. The opening 3| is aligned with an opening 32 in the back strip l0 and through which also the rivet may be extended. The

'member 29 is also provided with depending spring arms 33 which are preferably curved inwardly at 34 to provide locking shoulders 35 adapted to engage the wires I 4 and the outer free ends of the spring side walls ll. 7 I

In the operation of the device, the booster handle I 8 may be raised to open the ring sections and/when depressed, will close the ring sections. It will be observed that when the ring sections are closed, the booster handle lies in the same plane with the metal back strip. In the swinging movement of the ring sections, the contacting surface between two of the ring sections is the 1* single line, as illustrated in Figs. 3 and 4. The

reinforcing strips or buttons 29 may be shifted longitudinally ofthe strip to bring the openings 3| into alignment with the openings 32 of the back strip Ill so that the round'back of the looseleaf cover may be attached thereto by riveting. If it is desired to attach the back strip to a cover having a flat back, the buttons 29 may be readily removed from engagement with the back strip I 0.

In assembling the ring sections uponthe inbends l5, the T-slots 22 of the ring sections are drawn over the tapered ends of. the flanges 2|, and the ring sections are then drawn toward the central wider parts of the flanges 2 I. This drawing operation tightens the ring sections upon the flanges 2| and gives them the desired rigidity. At any later time,,if desired, the ring sections may be removed by exerting lateral pressurethereon; or, if desired, the ring. sections can be permanently secured to' the wires bytapping the wires adjacent theiianges 2|. w

While in the illustration given, we have shown the metal back strip equipped with twobooster levers l8, it'will be understood that one of the levers may be omitted. if desired. There is a distinct advantage in having two levers not only because of the facility forv operation by the user, butalso as an aid to'the manufacturer in securing the back stripl parts to the cover of a loose-leaf book. In the latter operation, the manufacturer need nottake pains to secure the back strip in a four, or more rings may be as readily employed by varyingjthe number of in-bends l5 employed.
