ronrroLro.

Application filed March 1927. Serial 1Y0. 172,957.

This invention relates to improvements in portfolios wherein means are provided for supporting upturned leaves, and refers more partici'llarly to portfolios intended to be utilined also as stands so that downturned leaves may lie against one cover of a portfolio and upturned leaves against a rest piv otally mounted on the cover.

Another object of the invention is to provide a portfolio having a very simple form of means for supporting upturned leaves which can be very cheaply manufactured, is amply strong enough to support any number of leaves without sagging, and which will not noticeably increase the weight of the portfolio or add to its size.

With these and other objects in view which will be mentioned hereinafter, the invention is more fully described with the aid of the accompanying drawings, in which:

Figure 1 illustrates a view of a portfolio almost in closed position, and part of the rest for upturned leaves turned back against one of the covers.

Figure 2 shows a portfolio open by lying flat and with the rest for upturned leaves still turned back against one of the covers.

Figure 3 shows the portfolio in use as a stand with some leaves upturned and lying against the rest which is in upwardly and rearwardly inclined position.

Fig. t is a detail.

1 and 2 designate the covers of a portfolio which are flexibly connected at their inner ends by a strip 3. To the latter a binder at is attached in any desiredmanner to hold the leaves 5. The binder shown in the accompanying drawings is an ordinary ring binder, though, when desired, any other form of binder. for holding either loose or bounr leaves may be employed.

It will be noted that the covers 1 and :2, open about the strip 3 until their inner surfaces form the outer sides of a triangle with the strip at its apex. A preferredmeans of holding the outer ends of the coversl and 2 in spaced relation to one another consists of a spacer member 6 fie ribly connected to the outer end of the cover 1, said member having an extension 8 flexibly secured to its outer end, and fasteners 9 on the extension 8 to engage corresponding fasteners 10 on the outer ends of the cover 2. Other means for accomplishing this purpose may however be employed. 7

On the'iuner surface of the cover 1 bean binder i as by a rivet 21 ings 11 are so secured that the centre line through them is substantially parallel with theends of the cover. These bearings sup port the inbent extremities 12 of theU- shaped rest 1%, which may either be downturned against the cover 1 as shown in Figures 1 and 2, or upturned as shown in Figure 3. The length of the transverse portion 143* the rest should be such that the side portions 149 are a greater distance apart than the width of the leaves 5; andth e length of the side portions 1 9 and the posi} tion of the bearings 11 should be such that when the rest is upturned the transverse portion is so positioned as to afford maximum support to the leaves, and when the rest is downturned the said transverse portion will lie against the cover 1 below the outer ends of the leaves 5. l

As indicated member may in Figures 2 and 4 a locking be slidably mounted on the which passes through a slot 22 in the member, so that the latter may be moved outwards until its outer end 23 extends over one of the side portions 14 of the rest 14. In this manner the rest may be positively held against the binder when it isin upturned position. I prefer that the sides of therest intermediately of their length bear against the binder rather than against the cover because the binder is generally made of metal and is therefore better able to withstand rearward pressure from the weight of the leaves. The height of the bearingsll above the surface ofthe cover to which they are attached is preferably such that the rest when upturned line substantially at thesame angle as the cover on which it is mounted.

While in the foregoing the preferred embodiment of the invention has been described and shown, it. is understood that the con slruction is susceptible to such modifications as fall within thefscope of the appended claims. l

What I claim is: L

1. In a device of the character described, the combination of a cover,l eaves mounted in proximity to one end ofthe cover so as to normally lie thereagainst, and a restso mounted on said cover that it'is adapted either to be outwardly turned andeigtend beyond said cover to support outturned leaves, or to be turned inwardly against said cover.

2. In a device of the character described,

the combinationas described in claim 1 wherein the rest is mounted on the same side of the cover as that against which the leaves normally lie. I

3. In a device of the character described, the combination as described in claim 1 wherein the rest is mounted on the same side of the cover as that against which the leaves normally lie, and wherein the rest may be moved outwardly or inwardly againstthe cover without disturbing the leaves lying against said cover.

t. In a device of the character describer'l, the combination of a cover, leaves mounted in proximity to the upper end of the cover so that they may be downturncd thereagainst, hearings on said cover, and a rest: having side members whose otl'set, ends are mounted in said bearings and a trans member coi'meeting the outer ends of side members, the latter being subslantially parallel and a greater distance apart than the width of said leaves, and said transverse member being; adapted to lie against: said cover below the outer margins 01 downturned leaves.

5. In a device of the character described in claim 4;, the combination wherein the bearings are so positioned on the cover and the side members are of such length that when said rest is upturned the transverse member is so located as to al'lord support for upturned leaves. e V

(5. In a portfolio, the combination of two covers flexibly connected at their inner ends so that they may be opened until their inner surfaces face outwardly and downwardly from said flexible connection, a binder mounted in proximity to the inner end of one of said covers, leaves on said binder adapted to lie downwards against said latter cover, and a rest so mounted on said latter cover as to be adapted to extend upwards above the inner ends ol said latter cover to support upturned leaves or to be downturned against said latter cover.

In a porttrdio the combination of two covers flexibly connected at their inner ends so that they may be opened outwards until their inner surfaces face outwardly and downwardly from said flexible connection, a binder mounted on said flexible connection, leaves on said binder adapted to lie down "wards against one cover, and a rest pivotally mounted on the inner side oi said latter cover so that said rest when upturned will extendabove said binder and be supported intermediately of its length thereb said rest when upturned being adapted to support upturned leaves, and said rest when downturned being adapted to lie against said latter cover.

8. In a portfolio, the eon'ibinatirni of two covers flexibly connected at their inner ends so that they may be opened outwards until their inner surfaces :t'ace outwardly and downwardly from said flexible connection a binder mounted in proximity to the inner end of one of said covers, leaves on said binder, hearings on one ot' said cover mem bers against which downturned leaves are adapted to rest, and a three-sided rest haw ing ends mounted in said bearings, two sides of said rest being spaced wider apart: than the width of said leaves, a third side so positioned as to be adapted to lie against said latter cover below the outer ends of said leaves when downturned, said two sides being adapted to be supported intermediately ol their length by said hinder when no turned.- and said leaves being adapted to h supported by the third side of said rev-l when they and said rest are 11].)l2ll1'lletli 9. in a portfolio, the eon'lbination oi two corers flexibly connected at their inner ends so that they may be opened outwards until their inner surfaces face outwardly and downwardly from said flexible connection a binder mounted on said flexible comm-- tion, leaves on said binder adapted to lie downwards against one cover, a rest pivotally mounted on said latter cover so that said rest when upturned will extend above said binde and be supported intern'icdialw ly of its length thereby, said rest when upturned being adapted to support upturned leaves, said rest when downturned being adapted to lie against said latter cover, and means for positively holding said rest against said binder when said rest is in upturned position.

10. In a portfolio, the combination as described in claim 7 wherein means are provided for holding the pivotally mounted rest in upturned position.

11,. In a portfolio, the coml'iination o1 two covers flexibly connected. at their inn r ends so that they may be opened outwards until their inner surfaces face outwardly and downwardly from said flexible connection. a binder mounted on said flexible connection, leaves on said binder adapted to lie downwards against one cover. a rest pirolally mounted on said latter cover so that when said rest is upturned it will ntend above said binder and be supported interlnediately of its length therel'iy. said rest when upturned being: adapted to support upturned leaves, said rest when downlurnwl being adapted to lie against said latter cover. and a locking; member slidable on said binder the outer end of which is adapled to hold said rest iMLfllDSlI said binder JAMES D.
