1 '0 all whom it may concern: I

Be it known that I, JAMES C. Dawsox, 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 Shiftable-Sheet Binders, of which the following is a speciused in connection withthe keeping of accounts and for similar purposes. The shiftlng of the sheets of these binders has for its purpose to distinguish those sheets upon which new entries have been made from other sheets in the binder. The present invention has for its object to improve the construction of binders and sheets of this class, and particularly to provide binders and sheets of such construction that the shifting of sheets may be positively controlled and cannot occur accidentally.

In the accompanying drawingFigure 1 is a perspective view showing a binder and upon the flexible back 12.

The binder mechanism preferably comprises a plurality of filing members, as 13, 14 and 15. In the form of construction which is shown in the drawing each of these filing members is composed of a pair of mating movable prongs, as 16, 17 '18, 19 and 20, 21, forming a complete but openable ring. When constructed in this way, that is with all of the filing members 13, 14, 15 in the form of a complete ring or loop, it is desirable that at least one of the rings, as 14,'be openable independently of the others. In the arrangement illustrated all of the rings are adapted for independent operation. To

this end the prongs of which each ring is' composed are mounted upon separate .platesx as 22 and 23, 24 and 25, and 26, 27, respectively. The plates of each pairare shown as having pivotal engagement at their meet; ing edges and as being held in such engagement by a resilient retaining plate 28; This" retaining plate embraces the several pairs oi plates between its two side edges and the arrangement provides that durin the operation of any one of the rings, as; 12, the

corresponding plates, as 24, 25, arefmoved These sheets are a crtured alon one ed e to r ceive the several filing members, as 13,

1.4 and 15, and preferably these apertures are so constructed as to permit-the sheets to be shifted in the binder mechanism without disengaging them from the rings 13 and 15.. To this end elongated apertures, as 30 and 31, are provided for receiving the rings 13 and 15, espectively. As shown, the longer dimensionsof these apertures extend in a direction parallel to the adjacent edge of the sheet, whereby the shifting of the sheets is accomplished by moving them in the direction of the holding edge of the binder. The remaining. fi1ing member, as the ring 14, serves to positively hold the sheets in adjusted position \For this purpose two filing apertures, as\3 2, 33, are provided in the sheets for receiving the ring 14. Each of the apertures 32, 33 is of such restricted size as to prevent any movement of the sheets in the direction of the holding edge of the binder when the ring 14 is engaged with either of such apertures. Furthermore, the apertures 32, 33 are non-connecting. The sheets must accordingly be disengaged from the-filing member 14 to allow them to be shifted. When the filing member 14 takes the form of a complete ring, as shown, this can only be accomplished by opening the ring. It is for this purpose that the binder mechanism is "most desirably so constructed as to permit the ring 14 being opened independently of the other rings, as 13 and 15.

Vfhen'the parts, as 18, 19, of the ring 14 have a swinging movement for opening'and closing the ring, the apertures 32, 33, are elongated in a direction transverse to the holding edge of the binder to permit such movement of the parts of the ring when engaged with the sheet.

29 will preferably be arranged 'upon the rings 13, 14, 15, with the ring 14fengaging' the same aperture, as 32, of all of the sheets. 5 Usually the sheets will be arranged between suitable guide or index leaves, as 34. When. a new entry has been made on any one of the sheets 29, the ring 14 will be opened and the sheet disengaged from the ring 14 and shifted on the rings .13, 15, to a position in which one of its edges projects beyond the corresponding edges of the remaining sheets, as appears at35, Fig. 1. The shifted sheetis then filed upon oneof the of the ring 14 in its new position, and the ring closed. In the new position of the sheet the ring 1.4 is engaged with the other one, as 33, of the two apertures provided for receiving it and serves to positively hold original position. The new position of the sheet serves to difierentiate it from other sheets upon which new entries have not been made, whereby reference to the new entry to the new entry is no longer required, as when the new entries have been posted at the close of a dayls" business, the ring 14 will bevopened. and the shifted sheet re;

turned to its original position.

I claim as my'invention 1. In a loose leaf'binder, in combination, two pairs of mating relatively movable filing prongs, those of each pair forming a closed loop in one position. and. the move- -m'ent of a prong of one pair for opening the loop being independent of the prongs form- In the use of the binder all of the sheets parts 18, 19

the sheet to prevent its being returned to its.

may easily be had. NVhen a ready reference tures No stress --is laid upon the shape of' 'the,

15, the specific arrangementcept as may be particularly pointed out in 'first mentioned prongs of each pair forming a closed loop in one position and. the movement of a prong of one pair' for opening the loop be ing independent of theprongs forming the other loop, and a sheet running on the prongs of the last mentionedpalr, said sheet having sliding engagement with said prongs for'movement between two positions in a direction parallel to the plane of the sheet and transverse to the planes of the prongs and having engagementin one only of said positions with the prongs'of the other pair fixed against such movement.

3. In a l ose leaf binder, in combination,

.two paralle filing prongs, one thereof being laterally movable in a direction transverse to a line extending between the prongs,

and a sheet havingan aperture for receiving each of said prongs, the aperture for receiving the said movable prong being slotted in the direction of movement of the prong and the aperture for receiving the other prong being slotted in the direction of the said lineextending between the prongs.

4. In a loose leaf binder, in combination,

two parallel filing prongs, one thereof be ing laterally movablein 'a direction transverse to a line extending between the prongs,

and a sheet having a plurality of non-connecting" apertures for receiving the said movableprong, each of such apertures being slotted in the direction of movement of the prong, and an aperture for receiving the other prong slotted in the direction of the said line extending between the prongs, like parts of each of the first mentioned aperbeing located at equal distances from difierent parts of the said aperture which is slotted in the direction of the said line extending between the prongs.

- 5. A shiftable sheet provided with a slotted filing aperture and with a pair of other non-connecting apertures each slotted in a direction transverse to the length of the aperture and the two having like parts located at equal distances from dififerent parts of the said firstmentioned aperture.

6. A loose leaf provided with a pair of closed slotted filing apertures extending in relatively transverse directions and a part of one of said apertures being located in a line with the length of the other.

7. A' shiftable sheet provided with a pair of slotted filing apertures extending in rela tively' transverse directions, a part of one of said apertures being located in line with the length of the other aperture and having its edge which is adjacent said other aperture located at a distance which is less than the length of the said other aperture from an edge of the sheet which is transverse to the length of the said other aperture.

8. In a shiftable sheet binder, in combination, a pair of sectional filing arches, one

side of one of the arches being laterally movable in theplane of the arch for opening receiving the said arch having the movable side in a different position of the sheet.

10. In a shiftable sheet binder, in combination, a pair of sectional filing arches, one side of one of the arches being laterally movable in the plane of the arch for opening and closing the arch, and a sheet slotted in two directions which are transverse to each other for filing on the arches in one position and having an additional opening slotted in a direction which is parallel to the planes of the arches for receiving the said arch having the movable side in a different position of the sheet.
