RING ieoox.

Application filed April 13, 1925.

This invention relates to ring books, particularly such as are used for note books, temporary bindings and the like.

The primary object of the invention is to provide a ring book which is neat and compact and which at the same time is economical to manufacture. I

These and other objects are accomplished by this invention which is fully described and shown in the accompanying drawing, in

which:

Figure 1 is a cross-sectional view on the line 11 of Fig.2;

Fig. 2 is a front elevation of the back strip of the ring book when the covers are open showing one ring in operative position;

Fig. 3 is a similar view showing the ring partially removed; and

Fig. 4 is a perspective view of the ring. I

The embodiment illustrated comprises a back strip 10 of a relatively stiff material as hard fibre to which is secured meta-l back plates 11 by means of rivets 12. These back plates have inwardly turned edges 13 in which are formed opposing notches 14. The U-shaped ring 15 cooperating with this back plate has oppositely projecting ends 16, 17. These projections are adapted to fit under the inwardly turned edges 13, the lower portions of the U-shaped ring just above the ends 16 and 17 being adapted to snap into the notches 14.

It will be observed that the extensions are bent in opposite directions so that they give support to the ring 15 when pressure is exerted thereon in either direction and, at the same time, by pressing these projections in opposite directions, the ring'can readily be assembled from the back plate.

In assembling the ring is placed as shown in Fig. 3 with one end. in the right hand notch 14, the extensions 16 lying partially beneath one of the projecting edges 13. The opposite end of the ring from which the projection 17 extends then lies against the outer ends of one of the edges 13 and by pressing downwardly on this outer end. of the ring the ring will be slightly compressed as it rides over the rounded surface of the into the notch 14.

Serial No. 22,812.

To disassemble the ring, pressure is exerted on the ring 15 in the opposite direction from that'which is used in assembling and when the ring is compressed sufficiently to permit it to be forced out of the notch in the back plate, then it can be withdrawn.

When both of the rings, the other which is not shown, are removed, the note book sheets,

' also not shown,-may be inserted or removed in a well known manner and the rings inserted as has been described.

Thus, it will be seen a very neat and compact arrangement is thus provided. Front and back covers 18, 19 may be secured to single embodiment of this invention,it is to be understood that it is capable of many modifications. Changes therefore in the construction and arrangement may be made whichdo not depart .from the spirit and scope of the invention as disclosed in the appended claims.

I claim:

1. A fastening device for ring books and the like comprising a metal back plate having inturned edges, notches in said edges, and a ring adapted to engage said notches and having oppositely disposed lateral extensions adapted to engage said plate and to lie beneath said edges to hold said ring in an erect position.

2. A fastening device for ring books and the like comprising a metal back plate having int-urned edges, notches in said edges, and a ring adapted to engage said notches and having oppositely disposed lateral extensions at its ends adapted to engage said plate to hold said ring in an erect position, said ring being movable laterally into and out of engagement.
