This novel combined structure may best be explained by reference to Fig. 1. Here it will be seen that the plates 7 provided With the struck up lugs 8 have been complemental- 1y positioned within the shell member 6 and the edges!) of the shell member turned over to secure the plate members in operating position.

In addition to the inturned edges 9, the shell member is also provided with the relatively short outturned flanges or edges 10. It will be obvious that the flanges 4 may be turned inwardly as best shown in Fig. 1, whereby to securely grip theedges of the shell structure from the outside'so as to secure the Same in place. The outturned flange 10 being shorter than the inwardly turned flange 9, it will be obvious that the upper shell member 6 will completely cover the other parts ofthe base structure so as to present a very neat appearance.

As best shown in igs. 3 and 4, the plate members 7 are providedwith suitable extensions 11 and these extensions are in turn provided with suitable handle members 12 where by the plate members may be moved relative to each other to open and close the ring members.

In Figs. ,5 to 8 I have illustrated the shell member 6 as being utilized as a base member in connection with a binder of the type having asmooth back member or, in other words, one without rivets, In this case, the binder, which may be designated 13, is provided with a suitable attaching member 14 which may be in the form of an arcuate shaped back plate initially provided with upstanding lugs 15.

This back plate 14 may be secured to the back of the binder as by gluing or otherwise,

and then the base member, completely assem bled as'i'llustrated in Figs. 2 and 6, may be lowered into position and the lug members 15 turned inwardly to engage the outwardly turned flanges 10 and thus positively secure the base member into position and at the same time cover up from view said securing means.

InFigs. 5 and 8 I haveillustrated a modified manner of form ing the end extensions. of the plate-7, wherein such extensions 16 and 17 are crossed over. so that it is merely necessary to move the end portions 18 ofthe extensions toward each other to open up the ring members;

important detail of the present invention resides in the peculiar fabrication of the plates 7and the attaching members 3 or 14 as the case may be. I amreferring here particularly tothe cut-away portions 20 in the plates 7 ,as best shown in Figs.1,3," and 8, and

positioning lugs 21 and 22, as best shown in Figs. 2, 6, and 7.

In the preferred method of assembly of the type of back member shown in Figs. 1 to 4, I prefer to cut away the edges of the plate 7 at such points as it is desirable to locate the attaching members 3. If desired, the edges 01 the plates 7 may be cut away substantially their entire length, as shown in Fig. 3 or such edges may be cut away only at the particular point where the attaching members 3 are located. The purpose of this is to positively eliminate any chance of binding when the flanges 4 are turned over into position, as shown in Fig. 1. The same situation would be true in assembling the type of binders shown in Figs. 5 to 8 but here, inasmuch as the lug members 15 are stamped out so as to be located at particular points, it will be obvious that the plates 7 may be likewise cut away along the edges corresponding to the location of the members 15. This structure is not shown as being necessary but is shown in Figs. 2, 3, 6, and 8 as being the preferred form.

The purpose of the lug members 21 and 22 is to position the flanges 10 so as to reinforce these flanges or what might be said the edges of the shell members while the flanges 4 or the lugs 15 are turned inwardly to secure the back member into position.

In the type of structure shown in Figs. 1 to 4, each attaching member 3 is preferably provided with upturned lugs 21 (as best shown in Fig. 1) so that when the assembled back member is lowered into position, as shown in Fig. 2, the flanges 9 will be positioned between the lugs 21 and the upturned flanges 4. Now, if the flanges 4 are turned inwardly, as best shOWn in Fig. 1, it will be obvious that the lug members 21 will prevent the longitudinal edges of the shell from being moved inwardly to far. In other words, these lug members 21 will insure a quick and positive locking between the flanges of the attaching members and the inturned flanges of the shell. It will be understood that the fit between the lugs 21 and the inturned edges of the shell member may be somewhat loose so as to permit the free turning in of the flanges 4.

In the structureshown in Figs. 6 and 7 it will be obvious that the lug members 22 may be positioned at substantially any desired points'solong as they reinforce the inner edges of the flanges 10 when the outer lugs 15 are turned inwardly to clamp the shell member into position.

Fig. 9 illustrates a modified manner of securing the base member to the back member in that suitable countersunk apertures are formed in the member 14 for receiving rivets 25, theheads of which are covered up by the cloth back of the binder. In this case the plates 17 are preferably held in position by the inturned longitudinal edges of a member 26' and the tops of the rivets 25upset by means of a suitable tool which may be inserted through apertures 27 and 28 formed in the top shell 6 and the plates 7 respectively.

It will thus be seen I have provided an extremely simple and compact base member which is adapted for universal use with substantially any type of binder. It will also be seen that by reason of my novel attaching means which permits clamping to the turned 19 over edge of the shell member from the outside instead of from the inside, I have made it possible to secure the base member to the back member at any point or points along the longitudinal. edges thereof. Thus if the binder calls for an unusually long shell mem her I have made it possible to secure the same to the back member at any number of points desired so as to securely and rigidly reinforce the same.

The shell member and ring structure is substantially the same as that disclosed in my above mentioned applications, and the attaching means in either form of binder is extremely simple, easy to manufacture, and easy to assemble.

lVhat I claim is: 1.. The method of assembling a base memher and securing the same to the cover of a loose leaf binder, which comprises enclosing paper-retaining means within a one-piece shell member, fixedly securing attaching means to the back of the cover at any desired point or points, placing the shell above the attaching means and then turning over a portion of said attaching means to contact with a portion of the shell but concealed by the upper surfaces thereof whereby to fixedly secure the shell to the back of the binder.
