LEAF FLIPPER Filed Sept. 11, 1929 2 Sheets-Sheet 2 INVENTOR/ f8 lwj taq m rlvass fifroizivEys Patented Jan. 10, 1933 UNITED STATES PATENT OFFICE REGINALD M. RAYNOLDS, OF NEW YORK, N. Y., ASSIGNOR TO MCMILLAN BOOK COMPANY, OF SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK LEAF FLIPPER Application filed September 11, 1929.
This invention relates to a new and improved leaf flipper for use with loose-leaf binders particularly loose leaf binders of the type known as split ring or arcuate prong binders and is a continuation in part of my co-pending application for a leaf flipper filed Oct. 13, 1928, Serial No. 312,240.
In binders of the split ring or arcuate prong type, the loose leaves used in the 1g binder are provided with spaced apertures along one edge through which the rings or prongs extend, the main body of the sheets lying upon a cover hinged to the back member which carries the rings or prongs.
When the binder is opened, the leaves will be resting upon a cover with their inner edges adjacent the lower part of a ring or prong. I When the binder is then closed, the leaves will be carried upwardly on a cover which will cause them to slide along the rings or prongs.
Due to the fact that there is considerable friction between the leaves and the rings 5 when the former are moved along the latter and due to the fact that the loose leaves themselves are made of a comparatively delicate thin paper, this movement of the leaves along the rings is apt to result in injury to 0 the leaves particularly the lower ones of a set.
For the purpose of supporting the leaves when they are moved on the rings and also for the purpose ofso positioning the apertures in the leaves with reference to the rings that the friction between them may be minimized to the greatest possible degree, I have found that a supporting member slidably carried on the rings and interposed between the sheets and a cover will to a considerable extent protect the leaves from injury during their movement on the rings.
In order to accomplish the desired result in the best way, the supporting member or -1 flipper, as it is commonly called, is provided with a means to position the leaves with re spect to the rings in such a way that the rings are kept in approximately the central part of the apertures in the sheets.
The main object of my invention is to pro- Serial No. 391,925.
vide a flipper which may be manufactured economically but which, at the same time, will be of such a design that it will act as a support for loose leaves and will also act as a M means for positioning the loose leaves with respect to the rings.
Other objects and advantages relate to the size, shape and arrangement of parts all as will more fully appear from the following description taken in connection with the accompanying drawings in which Figure 1 is a perspective view of the preferred form of my device.
Figure 2 is a plan view partially broken away of a binder in the open position with two of my flippers in place and with loose leaves on one of them, the rings of the binder being shown in section.
Figure 3 is a section on line 3-3 of Fig- I, A ure 2. 10
Figure 4 is a perspective view of a modified form of flipper.
Figure 5 is a section on line 55 of Figure 4.
Although my device may be used with 76 various types of loose leaf binders, for the purpose of explaining the construction and operation of my device, I have here shown it as being used in conjunction with a loose leaf binder of the so called split ring type which 80 comprises a back member 1 with opposed covers 2 and 3 hingedly connected to the opposite longitudinal edges thereof.
An arcuate sprin plate 4 is secured to the upper surface of back 1 as by rivets or other convenient means, none here being shown, spring plate 4 having its opposite longitudinal edges return bent to form channels 5 and 6.
A toggle plate 10 having affiXed thereto a plurality, in this case shown as five, of half-rings 11 is positioned on back member 1 with one longitudinal edge in channel 5 of spring plate 4.
A second toggle plate 12 having aflixed thereto a plurality, in this case shown as five, of half-rings 13 is similarly positioned on back member 1 with its outer longitudinal edge in channel 6 of spring plate 4.
A plurality of double headed buttons 14,
one only being shown, is positioned between the inner longitudinal edges of toggle plates and 12 with such edges between the heads of buttons 14.
The combined width of toggle plates 10 and 12 is slightly greater than the normal distance between channels 5 and 6 of spring plate 4 so that when the longitudinal edges of to gle plates 10 and 12 are in a plane below t e lane in which the outer longitudinal edges 0 such plates are positioned, in which position the upper ends of half-rings 11 and 13 will be in contact as may be seen from Figure 3, the parts will be held in this position by the resiliency of spring plate 4.
When it is desired to raise the inner longitudinal edges of toggle plates 10 and 12 above the outer longitudinal edges of such plate in order to se arate half-rings 11 and 13, such movement is permitted due to the resiliency of s ring plate 4.
hen such movement has been completed, the parts will be yieldingly held in their new position by the pressure of spring plate 4.
The downward movement of the inner longitudinal edges of toggle plates 10 and 12 and the op osite upward movement of such plates is limited by the buttons 14 which permit only alimited movement of the edges of togle plates 10 and 12 between the heads on the uttons 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 they may be sprung over the longitudinal edges of sprin plate 4 and cover plate 15 securely held in t at position.
Cover plate 15 is provided with slots 16 and 17 to permit the movement therein of halfrings 11 and 13 as the same are opened and closed, a slot 16 being provided for each halfrin 11 and a slot 17 being provided for each hal -ring 13.
The upper end of half-rings 13 are V- shaped in form so that they may enter V- shaped slots in the upper ends of half-rings 11 when the upper ends of the opposed rings are brought together, half-rings 11 and 13 being so ositioned on toggle plates 10 and 12 respectively that half-rings 11 will register with the opposing half-rings 13 when the rin lgs are closed.
he preferred form of my device comprises a substantially rectangular body portion 18 preferably made of fibre orv heavy cardboard. The body portion 18 is provided adjacent one longitudinal edge with a plurality, in this case shown as live, of spaced apertures 19 adapted to receive therethrough half-rings 11 or half-rings 13.
Adjacent edge of apertures 19 are positioned stops 20 which are formed by cutting in the edge of body 18, tongues, and bending the same into approximately V-shaped form so that the inner ends of stops 20 will be approximately at right-angles to body 18 to form stops against which the inner edges of loose leaves may abut when the body 18 and such loose leaves are in position on prongs 11 or 13.
The shaping of stops 20 in the manner just described will result in a notch 21 being formed in the edge of body member 18 opposite each of the apertures 19.
In Fig. 4, I have shown a modified form of flipper which comprises a substantially rectangular body portion 22 having spaced apertures 23 preferably oval in form.
In this embodiment of my invention, I do not form stops 24 therein provided from a portion of the body member 22, but I form such stops individually from other material.
These stops 21 are of an approximately inverted V-shaped form having their opposite bottom ends return bent as erhaps may best be seen from Figure 5 so t at the same may be clipped in position on body 22 with one end gripping body 22 at the outer end of an aperture 23 and with the other en gripping the outside edge of body 22.
Although if desired, a stop 24 may be provided for each aperture 23, I have found that two only are required for effective results if the same are in spaced relation and positioned as shown in Figure 4.
Operation In use it is desirable to use two of my devices, one cooperating with each of the covers of the binder and I have here shown in Figure 3, one of my devices in position on cover 2 with no loose leaves thereon and a second one of my devices in position on cover 3 with a plurality of leaves 25 in position on the device.
The leaves 25 are provided with apertures 26 so positioned that they register with halfrings 11 or 13 and for a purpose hereinafter to be described, it is desirable to have the distance between the centers of apertures 26 and the longitudinal edge of the sheet greater than the distance between stops 20 and the centers of apertures 19.
\Vhen the parts are in position shown in heavy lines in Figure 3 and the cover 3 is raised for the purpose of closing the binder, it will raise with it the outer ed of body 18 which will cause the outer en s of apertures 19 to contact with half-rings 13 and ride upwardly thereon, the inner end of body 18 moving outwardly along the upper surface of cover plate 15 to guide body 18 in its upward movement.
The notches 21 are rovided so that when the lower edge of body 18 has moved outwardly to the inner face of half-rings 13, half-rings 13 will enter notches 21 to permit the lower end of body 18 to continue to move outwardly which will permit body 18 to continue its upward movement on halfrings 13 without any appreciable friction between apertures 19 and half-rings 13.
In the modified form shown in Figure 41, I have provided notches 27, 28 and 29 which answer the same purpose as do notches 21.
When cover 2 is raised, it will in a similar manner carry upwardly the body 18 which is positioned thereon and in doing so will carry upwardly with it any sheets 25 which may be positioned on its upper surface.
The relation of parts is such that when the binder is in the opened position the inner longitudinal edges of the sheets 25 will rest against the stops 20 on body 18 and inasmuch as the distance between the inner longitudinal edges of sheets 25 and the centers of apertures 26 is greater than the distance between the stops 20 and the centers of apertures 19, the apertures 26 in sheets 25 will be held in such a. position that the outer edges of apertures 26 will be held in spaced relation to the outer surfaces of half-rings 13 and there will be no tendency for sheets 25 to bind on halfrings 13 during the initial upward movement of such sheets and thereafter throughout their travel.
In Figure 3, I have shown in heavy lines the binder in the open position with sheets 25 on a body 18 and I have shown by dotted lines the same parts in the partially closed position.
It will be understood that the material from which my flipper is constructed and the material from which stops 24 are constructed may be varied to a considerable extent and it will also be understood that the size, number and relative position of the apertures 19 and 23 and also the height and relative position of the stops 20 and 2& may be varied as desired to adapt my device so that it may be used with different types of binders, for although I have shown and described a specific structure and form of part as an exemplification of an embodiment of my invention, I do not desire to restrict myself to the exact size, shape or relation of parts as various changes may be made within the scope of the appended claims.
