This invention relates to a new and improved leaf flipper for use with loose leaf binders and is particularly well adapted to be used with loose leaf bindersof the split ring or arcuate prong type.

When binders of this type are open and it is desired to close them by moving the covers towards each other such movement of the covers will move the sheets. in thebinder around the binder rings or prongs. The sheets of such binder are held in position by virtue of the fact that they are provided the outside edges the binder the outer edges of the sheets will be raised above the inner edges of'the sheetswith the result that the rings or prongs will assume an oblique position with'reference to the apertures in the sheets which will cause the sheets to bind on the rings or prongs to r a certain degree and resist movement around such rings orprongs. The sheets usually used with this type of binder being thin there is considerable possibility of injury to the sheets when they are thus forced along the rings. or

. sheets which are adjacent to the covers.

. In order -to permit'the movement of the sheets along thefirings or prongs it is desirable to provide a means which will provide a support for the leaves during such movement and which will also hold-the leaves in such a position with reference to the rings or prongs that there will be no tendency of the leaves to bind on the prongs during their movement, and the main object of my invention is to provide a device which may beinterposed between the leaves of a binder and the covers of the binder to act as a support and guiding means for the leaves while the binder is being closed. Other objects and advantagesrelate to the size, shape and arrangement of parts all as will more fully appear from the following description taken in connection'with the ac companying drawings, in which'z' Figure 1 is a perspective view of theprcferred form of my device.

. For the purpose of explaining the construcprising a back member 2 and covers 3 and 4 connected to'back member 2 by flexible hinges 5 and 6 respectively; A curved spring plate 7 is afii'xed to the upper surface of back' member 2 by rivets or otherconvenientuneans, not

shown. Spring plate 7 has its opposite prongs, which is particularly true of thelongitudinal edges return'bent to form channels 8 and 9'. A toggle plate 10 having aflixed ."tion and operation of my device I'have here shown one type of.a split ring binder 1 com- 30 thereto a plurality, in this case shown as five, '4

of half rings 11 is positioned on back member 2 with one longitudinal edge in channel 9 of. spring plate 7. A second toggle plate 12 having aflixed thereto a plurality, inthis case shown as larly positioned on back member 2 with its outer longitudinal edge in channel 8 of spring plate 7. A plurality of double headed buttons 14, one only being shown, arepositioned between the inner longitudinal edges of toggle plates 10 and 12 with such edges bje-- five, of half rings 13 is simitween the heads of the buttons 14. The com- ,bined width toggle plates" 10 and 12 is slightly greater than the distance between

channels

8 and 9 of spring plate 7 so that when the inner longitudinal edges of toggle plates 10 and 12 are below the outer longitudinal edges of such plates, in which position the upper end of

half rings

11 and 13 are in contact, the parts will be held in this position by the pres- 10 sure of spring plate 7. When it is desired to raise the inner longitudinal edges of toggle plates 10 and 12 above the outer longitudinal edges of such plates to

separate half rings

11 and 13 suchmovement is permitted by the resiliency of spring plate 7, and when such movement has been completed the parts will be yieldingly held in that position by the pressure of spring plate 7 The movement downwardly of the inner longitudinal edges of toggle plates 10 and 12 and the corresponding upward movement is limited by the buttons 14 which permit only a limited movement of the edges of toggle plates 10 and 12 between the heads of buttons 14.

A curved cover plate 15 is positioned above toggle plates 10 and 12. Cover plate 15 has its longitudinal edges return bent so that it may be sprung over the longitudinal edges of spring plate 7 and beheld securely in that position. Cover plate 15 is provided with a V-shaped slot in the upper end of half ring.

slots 16 and 17 to permit the movement therethrough of-

half rings

11 and 13 as the same are closed and opened. The upper end of half ring 11 is V-shape in form so that it may enter 13 when the two rings are brought together,

half rings

11 and 13 being so positioned on toggle plates 10 and 12 respectively that half ring 11 will register with opposing half ring 13.

The preferred form of my device, as perhaps may best be seen from Figure 1, consists of a substantially rectangular shaped body 18 made of metal or fibre or other sulfi- -ciently stiff material. Body 18 is provided with a plurality, in this case shown as five, of oval apertures 19 so positioned that they will register with either half rings 11 or half rings 13 when the body 18 is placed in posi tion in the binder. Cover 18 is formed with an approximately V-shaped trough 20-positioned between apertures 19 and the edge of body 18. Trough 20 is so formed as to provide a vertical ledge or stop 21 adjacent apertures 19 and in spaced relation thereto. In

the distance between ledge 21 and the center of oval apertures 19.

When the parts are in the position shown in Figure 3 and cover 3 is raised for the pur pose of closing the binder it will raise with it the outer ed e of body 18 which will cause the outer end of aperture 19 to contact with half ring 13 and ride upwardly thereon, the inner end of body 18 moving outwardly alon the upper surface of cover plate 15 to guide body 18 in its upward movement. The notches 22 are provided so that when the lower edge of bod 18 has moved outwardly to the inner side of alf rings 13, half rings 13 will enter notches 22 to permit the lower end of body 15 to continue to move outwardly, which will permit body 18 to continue its upward movement'on half rings 13 without any binding of apertures 19 on half ring 13.

When cover 4 is raised in a similar manner the body 18 will move upwardly in the same way as the body 18 moved upwardly on cover 3 as just described, and in doing so it will carry upward with it the sheets 23 which are positioned on its u per surface. The relation of parts is such that the inner longitudinal edges of sheets 23 will rest against the ledge 21 on body 18, and inasmuch as the distance, as just described, between the inner longitudinal edges of sheets 23 and the centers of apertures 24 is greater than the distance between ledge 21 and the centers of apertures 19 the apertures 24 in sheets 23 will be held in such a position that the outer edges of apertures 24 will be in spaced relation to the outer surfaces of half rings 11 and there will be no tendency for apertures 24 to bind on half rings 11.

In Figure 3 I have shown in heavy lines the binder in the open position and in dotted lines the binder in the partially closed position.

In Figures 4, 6 and 8 I have shown modified forms of my device which are designed to function in a similar manner as the manner in which the device shown in Figure 1 functions, the difference being that I form my ledge or stop in a different manner.

In Figure 4 I show a body 25 having oval apertures 26 similar to apertures 19 and having notches 27 similar to notches 22 but in this embodiment of my invention I form the ledge or stop 28 by bending a portion of the edge of body 25 at right angles to such body and by then bending the outside edge of body 25 into a plane parallel with the plane in which the main portion of body 25 is disposed.

In Figure 6 I show a body 29 provided with oval apertures 30 similar to apertures 19 memes with oval apertures 36 similar to apertures 19 and having notches 37 similar to notches 22. In this embodiment a series of stops 38 are formed by return bending onto the upper I, the size,

. ralityo surface of body 35 the material which was struck therefrom to form slots 37.

In Figure 10 I show a device similar to the device shown in Figure 4 having a body 39, spaced apertures 40, slots 41 and a ledge or edge of body 39 which carries slots 41 is. curved downwardly towards the plane in which the main body 39 is disposed so that the inner edge of my device will more quickly contact with'cover plate 15 when the covers '3 and 4 of the book are raised.

It will be understood that the material from which my device is constructed may be varied as desired and it will also be understood that number and relative position of the oval apertures 19 and the notches 22 and the similar apertures and notches shown in Figures 4, 6, 8, and 10, and also the height and relative position of the ledge or stop 20 and the similar ledges or

steps

28, 32, 38 and 42 may be varied as desired to adapt my device to be used with difler'ent types of binders, -for altho I have shown and described a specific structure and form of part as an exemplification of embodiments. of m invenplurality of spaced notches in alinement with the spacedapertures. Y

In witness whereof I have hereunto set my hand this 26th da of September, 1928.
