Application fi1ed=ApriI 7, 1927. Serial ism-181,753.
This invention relates to loose leaf bind-- ers, and has for itsprima'ry object the provision ofa novelty constructed binder which incorporates principles not heretofore utilized/in the making ot a post or stub binder.
@ne: of'theobjects of this invention is to provide a: binder whereinv an arcuate spring.
plate is used to'maintain pair of cO-a'ct'ing toggle plates in the proper" operativerela tion, which plates are each provided with a: laterally extending wall having sheet-clamping; members h-ingedly carried thereby, which sheet-clamping members rigidly support the sheet-engaging. elements. Another object ofthis,inventionis the provision or a loose leaf binder wherein the toggle plate principle isused and: is combined with certain post binder parts, all; being arranged to provide a hlghly efiiclent bindenwvhich is adapted to bemoved' to the open or closed position without the utl-llzih' t-ioir of complicated mechanism.
Minor objects of this. invention Wlll' appear during. the; course of the detailed speci fications referring: to'theaccompanying drawing, wherein Figure l, is a perspective View of a loose lea-i binder madein accordance with this invent-ionL- o Fig. 2,-isan end view 0% the working parts thereon-showing the; binder in the closed position.
Fig 3, is a; similar vlew, showing; one of the binder covers in the open position, and
Similar reference characters refer to like parts thruout' the'several views, and the numoral 5,-designates the'well knowrr arcuate spring back plate, which is curled inwardly along its two edges-to'eiigage a pair of toggle. plates 6, which are articulatedralong. their adjacent edges. In this instance, 't-he joint connectingthe-twoatoggle plates 6 1s 11] the. form'fofta: pianohinge, andthe pintle 7, precludes separation. Both toggle plates 6 are of such a width that the spring plate 5 will snap them to the position shown in Fig; 4-, from that position shown in Figs. 2' and 3', w-hena slight upward force ise'xerted tlhereonr il o properly' carryout this inventie'n', each toggle plate 6 should be prowith an upstanding. lateral. wall;
which is rigid with the, toggle plate 6, is co-extensive longitudinally therewith, and extends laterally therefrom along, a line spaced: inwardly from the edge engaged by the curled over portion of arcuate springv plate 5. In this manner, it is to; be seen from the drawing, that each toggle plate 6 is sub stantially T-shaped. The outer edge of the laterally extending wall 8 is curledin the ordinary fashion to formpintle bearings 9,v
thrir which: passhinge rod- 10, to engage and: hingedl-ysupport the sheet clamping member'lQ. As shown in the drawing, and espe cially Figs. 2 to- 4 inclusive, each of sheet clampingmembers 12-, should be rebent upon itself to provide an extended portion on each side of: hinge rod 10; Each sheet clamping member 1-2 is provided with a plurality of Lip-standing: sheet engaging posts 1-3 ,the posts of one member '12- being arranged in a staggered relation to the posts of the other,
and as sliowlrin Fig.1, the posts of one clamping member 12 are, long enough to extend to the, other member 12 when the binder isin= the closedpositi on. These longer posts 13 support binder sheets 14, and when the binder is closed extend 'into'sockets 15 provided in: opposed relation in the opposite member 12. The'short cr. posts 13 merely extend into the sheets" 14: adistance substantially half way across the binder thickness. The binder covers 1 6 are hingedly securedto the operative parts,and' as'shown, it is dcsirableto cause-them to be hingedly supported by hingerod 10; In this manner rod' 1 0 maintains: the covers 16 in the proper position, whereby they may act as levers when thewtoggle plates and related parts of the binder are moved to the open and closed po sition. Covers 16 are joined as clearly shownin the drawings to" rod 10, by thewcll Operation. When the binder made in aeeordancewita .their proper relation.
this invention is in the position shown in Fig. 1, sheets 14 may be slipped over the longer posts 13. They will lie in a flat position as shown in Fig. 3. In Fig. 2, the binder is shown in the closed position with covers 16 lying against the sheets 14-. l/Vhen opening the binder to make an entry on any one of the sheets contained therein, it is neeessary to merely swing the top cover 16 back around hinge rod 10. The swinging movement of this cover 16 will be limited when it strikes the curled edge of arcuate plate 5. To remove or insert sheets, it is merely necessary to continue the swinging motion of cover 16, apply a small amount of force and the leverage will pull short posts 13 out of engagement with sheets 14, and cause the sheet engaging member 12 to attain the position shown 'in Fig. 3. The longer posts 13 willobviously support all of sheets 14 in Before snapping the binder to the closed position,.it is necessary to actuatethe toggle plates 6 to the position shown in Fig. 4. 16 in each hand, it is but necessary to swing the entire mechanism about the hinged rod 10, shown on the left in Fig. '3 to a point where the edge 17 strikes the face of cover 16. As: soon as this edge 17 strikes, the cover shown at the left in Fig. 8, will exert an upward force along the articulated edge of toggle plate 6 thru wall 8, the curled edge of arcuate plate 5 against which it is bearing acting as the fulcrum point. Continual pressure snaps the two articulated toggle plates 6 up to the position shown in Fig. 4E, and as soon as this position is reached, closing action may be started, and as covers 16 are moved to the closed position around hinge rods 10, the short posts 13 swing to a position immediately over the perforations of sheet 14, which they are to enter. Cover 16 to the left of Fig. 1, presses against the over-lapping extension of member 12, carries member 12 around rod 10, and causes edge 18 to bear against wall 8. When this positionor relation of parts is reached, the short posts 13 are about to enter their respective sheet openings, and continued force snaps toggle plates 6 back into the position shown in Figs. 2 and 3. This quick action draws the short posts 13 into the sheet openings, and the two covers of the binder are closed. Since each of covers 16 is independently hinged, it is not necessary to actuate the spring plate 5 every time the binder is opened. 7
The advantages of a binder made in accordance with this-invention are obvious, altho many modifications in specific struc ture are possible; the preferred embodiment illustrated in the drawings, is desirable. It is rugged, cheap to make, highly eflieient, and has no involved'mechanism likely to get out of order Having a binder cover Having thus described the invention what I claim as new, and desire to be secured by Letters Patent is:
1. In a loose leaf binder, the combination spectively.
