. LOOSE-LEAF FILE AND BINDER.

Application filed. January 16, 1923. Serial No.612,915.

Our invention relates generally to that class of devices employed in holding in place the leaves or. sheets of loose-leaf books of account or similar aggregations of loose leaves and the object of our improvements is to provide a simple and efficient device for this purpose which will hold the leaves firmly in place andat the same time permit of their ready and convenient shifting or removal.

The invention will be best understood by reference to the accompanying drawings, illustrating an embodiment thereo.f,Fig. 1 of wh ch shows an elevation of the device in position to hold the leaves in place. Figure 2 and Figure 2 are perspective views of amodilied. form of the two parts of the device positioned ready for engagement, or to permit the removal or addition of leaves: Figure 1 is a section onthe line 121*, Fig. 2". Fig. 3 is a plan view (partly broken away) of a book with the binder in its holding position: Fig. 4 shows an end view of the binder with a leaf of the book turned over: Fig. 5 shows a section on the line 55 Fig. 3: Figure 6 shows a vertical section. Fig. 7, a plan view partly in section, Fig. 8 a vertical elevation and Fig.9 a plan view of a locking device which may be employed to hold the binder in place and Figs; 10 and 11 show rcspectivcly a vertical section, and a plan view of a modified form of pillar by which the end arches are held in engagement with their pillars.

Referring to the drawings, A,indicates a base plate which is secured to that cover of the book on which the loose leaves are carried and parallel and adjacent to the back thereof and to which are secured a series of tubular pillars, B, 13, arranged to engage corresponding perforations in the book leaves. C, C, D, D, etc. indicate a series of curved arches which are secured together at one end of each by a back rod, E, and are so positioned that when the binder is put in place for use they will respectively enter the openings of the tubular pillars, B. Two of the arches, as the end arches, C, C, are materially longer at their free ends than theintermediate arches. D, D, so that in putting the hinder in position for use, the end arches are inserted first in the corresponding pillars. By this means the intermediate arches, D, D,

are guided into the openings of the pillars with which they respectively engage and the device is readily ut in place. This is of especial advantage in cases where a considerable number of arches is required as with loose leaves of different length as shown in Fig. 3, where the number ofarehes adds to the diiliculty of guiding them into the corresponding pillars. Obviously other arches thanthosc at the ends may be made of greater length than the others and used as guides, though we prefer to use the end arches for ths purpose because of greater convenience of manipulation.

The longer arches, C, G, are preferably so arranged that, while they can be readily guided into the tubular pillars, they will, when in position, have a sufliciently positive engagement with the pillars to hold the binder securely in place. Thus the arches, (1,0, may be so positioned that they will have a slight lateral displacement inrelation to the corresponding pillars so that, when they are in position in the pillars, the spring of the metal of which they are composed will cause themto exert a lateral thrust against the interior of the pillar walls. Other means to the same end may be employed as, for example, that illustrated in Figs. 10and 11, in which the pillars, B, [which receive the arches, C, are made of slightly lesser diameter than the arches and are provided with a vertical slot, 7), so that when the arches are, put in position they are gripped and held by the pillars. i

lVhile the means above described are ordinarily sufficient to hold the binder in place against accidental displacement a positive locking. device may, if desired, be employed, such, for example, as that illustrated in Figures 1 and 2, consisting of one, or more, flexible pieces of metal, G, projecting from the side of the base, A, to which they are secured, or of which they form a part. Each piece, G, provided at its outer end with a curved upturned catch, 9, which, when the arches. C, D, are pushed down into placein the pillars, B, engages the back, E, and holds the binder firmly in place. To release the binder the catch, 9, is pushed down out of engagement with the back, E, and the arches can then be readily lifted out of engagement with the pillars, B. Another form of locking device which may be employed instead of, or in addition to that above described is illustrated in Figs. 6, 7, 8, and 9. In this case the longer guiding arches, G, C, are made of such length as to extend to. the bot tom, of the corresponding pillars B, and are provided, near their lower ends, with notches, e, e, which register with openings, (Z, (Z, in the pillars, l3. Pivotally secured to the base, A, are plates or blades, ll, so positioned that their free ends may be moved into the openings, diand engage the notches in the arches, C. Thus the binder is held locked in place until the plates, F, are moved so as to disengage them "from the notches. e.

In using the device the loose leaves are put, in place on the pillars, l3, and the guide arches, C, C, are directed into the openings of the eorrespoiuling pillars and pushed down, whereupon the other arches enter the respective (.orrespouding pillars.

"lhe binder is. then in operative position as shown in l ig. 1, and any number of lec ves can be turned back upon the arches so as to t re access to those below. ln case it is desired to remove any lea'li those above it. are turned back upon the arches and the arches are withdrawn from the pillars, the turned-back leaves resting upon the back, E. The leaf desired can then be removed and the binder returned to place.

Our invention provides an extremely simple and inexpensive device for the purpose indicated, which can be put in place andremoved without ditliculty and which is securely held in position, advantages which will be readily appreciated by those familiar with the art.

Having thus described our invention what we claim as new and desire to secure by Letters'Patent is:-

1. A loose-leaf binder comprising a base, tubular pillars secured to the base and others and means for positively locking said longer arches in the corresponding pillars.

3. A loose-lent binder comprising a base,

teal? engaging tubular pillars secured to said base and adapted to engage pertorations in the loose leaves, a plurality of connected arches adapted to engage said pillars, two of said arches having pillar engaging portions of greater lei'igth than the others, and locking means tor locking the arches in engagement with the pillars.

A. looseleat' binder comprising a base, tubular leaf engaging pillars secured to said base and provided with apertures adjacent to the base, arches having portions adapted to extend into said pillars, and locking blades movably mounted on said base adapted to extend'into the apertures of the pillars, and engage the portions of the arches within the pillars to lock the arches with respect to the pillars.

In testimony whereof we allix our signa turcs, this 15th day of January, 1923.
