6 Claims.

My invention relates to that class of devices which are designed to hold a plurality of loose leaves and which may, if desired, be filled up from time to time. It is well known that ring books of this type even if equipped with a. oneinch diameter ring will hold only approximately one-half inch of sheets. Moreover, if you desire to insert or remove a sheet from the center portion of the bound sheets, it is an extremely diflicult job because of the fact that you have to swing part of the sheets over on one half of the rings and the other portion remains on the remaining half and if you do not wish to divide or make your insert exactly in the center it is necessary to remove a number of. sheets and replace them all of which is timewasting and uneconomical.

My invention has for its object to provide means for binding a number of loose leaves in a book in which the binder will hold its full capacity and in which it is possible to gain access to a leaf or to insert a leaf at any part of the volume without the slightest difiiculty.

My means of accomplishing the foregoing objects may be more readily understood by having reference to the accompanying drawings which are hereunto annexed and form a part hereof, in which Fig. .1 is an iosometric perspective view of a fragmentary portion of a binder with my attachment, the parts being shown in separate position for the sake of clearness;

Fig. 2 is a top or plan view of the binder with the parts in assembled position;

Fig. 3 is an end .view of the same;

Fig. 4 is a plan view of the device with the impaling pins separated from the metal back;

Fig. 5 is an end view of the same; and

Fig. Sis a section taken on the line 6-6 in Fig. 4.

Similar reference numerals refer to similar parts throughout the entire description.

As shownin the drawings, the binder is attached to a pair of covers I and 2. It comprises a metal back 3, one edge 4 of which is bent at right angles thereto so that the metal back in cross section presents the appearance of an L.

A hinge 5 is provided on the other edge of the metal back and a hinged bar 6 is secured thereto by means of a hinge pin 1 in the usual manner. This hinged bar 6 is provided with a plurality of impaling pins 8 and has a number of "perforations 9 formed intermediate the impaling pins. As shown the pins are three in numher though it will be obvious they can be any number desired. The ends I of the hinged bar are bent upwardly for the purpose of forming. a spring lock which will be hereinafter ex-" plained. The pins 8 are arcuate but ona very large radius so as to be almost straight and terminate in points which are adapted to enter but not pass through apertures ll formed in a" detachable bar 12 which also carries impaling pins l3 which areadapted to enter the apertures 9 formed in the hinged bar 6;

The detachable bar 12 is preferably formed of spring steel and has mounted adjacent its ends.

two locking pins l4 and I5. These pins are adapted to register with apertures 16 and I1 formed in the narrower portion 4 of the L shaped metal back 3. Notohes l9 are cut in the ends of the detachable bar I2 and thesenotches are engaged by the upper ends 18 as clearly seen in Figs. 3 and 5. The operation of the device is as follows: 1

The loose leaves (not shown) are provided with perforations adapted to register with the impaling pins and are placed upon the pins 8. The pins l3 are then inserted in the intermediate perforations and as thepoints on these pins are smaller than the apertures 8 so that only the points of the pins can enter the apertures the pins cannot pass through them, The hinged bar 6 is then swung over until it reaches the position shown in Fig. 3 when the detachable bar will pass beneath the portion 4 of the L shaped metal back 3 and the pins I4 and I5 will be brought into register with apertures l6 and Il. Due to the resiliency of the metal, out of which the detachable bar I2 is formed, pins l4 and [5 will at once enter theholes and the ends N3 of the upwardly bent portions In of the hinged bar will engage the notches IS in the detachable bar l2 and serve as a spring lock for holding the bar 12 firmly in place and will also prevent the bar I! from sliding forward. It will be obvious from the foregoing description of the pins 8, since they extend the entire width of the volume, that any desired number of leaves can be left impaled upon them when the detachable bar is removed for the purpose of gaining access to any leaf without the slightest difiiculty regardless of its location.

It will also be clearly apparent that the space between the hinged bar and the detachable bar can be completely filled with loose leaves.

To remove the leaves the ends of the detachable bar are pressed downwardly until the pins l4 and [5 are disengaged from the apertures 16 and Il when the volume can be swung upon the hinge 5 and as soon as the detachable bar is in the position shown in Fig. 5 it can be lifted up with as many leaves as desired leaving the remainder on the pins 8 or it can be lifted entirely off of the leaves and all the leaves in the volume will be left on the pins 8.

By making the impaling pins slightly arcuate in form I facilitate the fiat opening of the book.

It will be apparent from the foregoing that I have provided a structure which entirely overcomes the objectionable features pointed out in the ring binders used in this class of work and have attained the result by means of a very simple and economical form of structure.

It may well be in practice that some other form of locking the detachable bar to the metal back will be found and although I have shown and described the specific type of structure for this purpose, I wish to be understood that these illustrations are solely for the purpose of showing a preferred embodiment of the invention and not with any intention of being limited to the specific structure shown and described except as such limitations may appear in the hereinafter appended claims.
