T 0 all whom it may concern:

Be it known that 1, JAMES C. Dawson, a citizen of the United States, and resident of Webster Groves, county of St. Louis, and

, State of Missouri, have invented certain new and useful Improvements in Loose-Leaf Binders, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to that type of loose leaf binders in which there is used rocking hooks or arches for engaging the leaves to be bound, the invention being peculiarly well adapted for use in connection with checkbooks, price-books, catalogues, etc.

The object of the invention is to simplify the construction and action of devices of this kind; and it consists in the mechanism hereinafter described and which is illustrated in the accompanying drawings, in which- Figures 1 and 2 are detail plan views of the binder open, showing two forms in which the invention may be embodied; Figs. 3, 4-, 5 and 6 are details of the device showing the construction and operation of the parts.

The binder is preferably provided with the stiff side-boards l0 and 11, united by a limp back 12, to the inner face of which there is secured a metal plate 13, which has its side edges overturned to pivotally secure the pivoted member of the arches and to serve as the lock for securing them in their closed position.

The arches 1st, 15, are united by means of an integral pivot member 16, adapted to be housed within one overturned edge 17 of the plate 13. This overturned edge or roll is cut away, as shown at 18, 19, to accommodate the arches 14, 15, the recesses thus formed being spaced apart a less distance than the length of the pivot portion 16 of the arches, thereby permitting the latter some longitudinal movement. Each of the arches let, 15, is notched adjacent its free end, as shown at 20, for engaging the opposite overturned edge 21 of the plate 13, and this portion of the plate is recessed, as shown at 22, 23, to permit the ends of the arches to enter it, the arches being locked by sliding them along longitudinally of the plate 13 to bring their notches into engagement with the edge of the portion 21 of the plate, as shown in Fig. 3.

A single pair of arches 14:, 15, may be employed, as shown in Fig. 1, or two pairs may be used, as shown in Fig. 2. In the latter form of construction one member only of each pair of arches, as 2% and 25, being the arehest nearest the end of the plate 13, are provided with looking notches. As shown in Fig. (5 preferably the pivot portion 26 of such pair of arches is indented or recessed intermediate of its ends, as shown at 27, so as to be engaged by the inner arch of the opposite pair, thereby interlocking the two pairs of arches so that they will move longitudinally of the plate 13 in unison. This modification is not claimed herein but is made the subject of a divisional application. Apertured sheets are applied to the arches of such devices by first turning the latter back upon their pivots. The two pairs of arches, as represented in Fig. 2, have this advantage over the single pair in that all of the sheets, except the one to be removed or inserted, may remain upon the arches while they are open.

I claim as my invention 1, In a loose leaf binder, in combination, a pair of arches rigidly united by a common pivot member, one of said arches having a head; a bearing for the pivot member within which it is longitudinally movable; and a detent into which the arch head is brought into engagement by the longitudinal movement of the pivot.

In a loose leaf binder, in combination, a back plate having its side edges turned inwardly; a pair of arches; a pivot member uniting the arches and having a rotative and sliding bearing within one of the inturned edges of the back; such arches having notches at their free ends for engaging the opposite side of the back plate. 7

3. In a loose leaf binder, in combination, a back plate having its side edges turned inwardly, a sheet-receiving arch, a pivot member transverse to the plane of the arch and to which the arch is secured one of its ends, such pivot member having a rotating and sliding bearing within one of the inturned edges of the back plate, the other inturned edge of the back plate being notched and the free end of the arch being notched to engage the last-named inturned edge of the back plate and being movable into and out of register with the notch thereof by the sliding of the pivot member.

5. Ina loose leaf binder, in combination, an arch, a pivot member transverse to the plane of the arch and to Which the arch is rigidly secured atone end of its span, a bearing for the pivot Within which it is longitudinally movable, and a detent into which the free end of the arch is brought into engagement by the longitudinal movement of the pivot.
