3' Claims.

The present invention relates, to a ration point tally and more particularly to the means for rotatably mounting such a tally.

At the present time the conventional metal eyelet which is ordinarily employed as a means for providing a pivot about which a disk may rotate, in making computations as well as for other use ful purposes, is now less available for such use owing to the demand for metal vital to the war effort, and to provide a substitute pivot means whereby the operation of the disk is'not impaired,

but on the other hand improved, is one of the major objects of this invention.

Other important objects include: the provision of an invisible pivot for rotating indicating disks or rotating disks in general; the provision of. a novel combination ration card holder and ration point tally; the provision of a novel cover including integral fingers for rotatively attaching the disk to the cover; the provision of a novel cover foldable in such a manner as to provide a novel locking means for holding the integral fingers in their deflected disk supporting positions; the provision of a disk rotating axis having spaced peripheral points, of

contacts for supporting the disk rotatively therea device having an indicating disk which may be set to show some numerical value and which is turnably supported without the use of any pivot means whatever, the article when thus constructed being suited for use as an advertising novelty to be given gratuitously to patrons and prospective customers by various merchants.

Other objects, advantages and features of invention will hereinafter appear. In the accompanying drawings wherein is shown what is now considered preferred embodiments of the invention;

Fig. 1 is a front assembled view of one embodiment of the invention.

Fig. 2 is a section taken on line 2-2 of Fig. 1. Fig. 3 is a plan view of the device in its extended unfolded condition.

Fig. 4 is a view similar to Fig. 3 showing the first step in the folding operation, which, step shows the integral pivot forming fingers locked in their deflected operative positions.

Fig. 5 is an interior open view of a second embodiment of the invention.

Fig. 6 is a section taken on line 5-8 of Fig. 5.

Fig. 7 is a perspective View of the cover shown in Fig, 5 in a slightly folded condition with the rotating disk phan-tomally outlined in its operative position.

Referring in detail to the drawings, the cover portion of the device, as shown in the first four views, is made of a senii-rigid sheet material, for example, of a medium weight cardboard. Said cover portion comprises the flap 9 which carries the rotatable disk iii; the window containing flap or section 5 l and the stabilizing back flap l2.

Said disk-carrying flap I9 is shown having through it a central, circular aperture M. At the time this. aperture is punched out a part of the sheet material within its circumference is cut in such a manner as, to form one or more fingers or ears I-5 (four in the illustrated embodiments), these fingers, are therefore, integral with the cover member, and if plural in number, are all turned back adjacent to the same face of the flap 9 and cooperate to form a pivot means to rotatably attach the disk It to the flap 9. Said fingers are grouped around a common center and should be circumferentially spaced apart at equal distances from each other.

It is not essential that so much of the flap 9 be cut away as to form the complete circular opening shown, but is suflicient if rectangular extensions of the sheet material or cardboard be cut which are large enough to form said ears or fingers. l5.

The. disk Ill has at its center a circular opening Illa of about the same diameter as the opening l4 through the flap. 9., and before the fingers I5 are turned back the disk and flap are contacted in a face-to-face manner with their apertures registering, with each other, and then the fingers are turned back in an overlying relation to the disk to form a pivot therefor.

The window flap II is so called because it is provided with a window or sight opening ll through which rows l8 and IQ of numerals inscribed on the disk may be read.

The flaps 9 and H are foldably joined along the fold line 2!, the edge portion of the cover, being cut away at 22 thus forming a notch at each end of said line, this facilitating the folding over of the flap 9 upon the adjacent section ll of the cover, whereupon said section retains the fingers E5 in a constricted space in their down bent position causing them to form a dependable pivot means for the disk.

At the juncture of the fiap or section II with the stabilizing flap or section 12 there is a fold line 25 at each end of which the cover has cut into its edge a notch 25. Along the midlength portion of this fold line extends a slit or narrow slot 21 through which is projectable a small segment of the circumference of the disk It] when the cover is in the folded condition shown in Fig. 2, this projecting part of the disk enabling the user to rotate it manually in the step-bystep fashion required to progressively step up the numerical values indicated by the numerals thereon as seen through the sight opening l1. It is to be understood that the cardboard or other sheet material of which the cover portion of the device is made will be sufficiently resilient to enable the assembler to spring the slotted edge portion of the cover over the part of the mounted disk IE! to be exposed when the flaps 9 and H are folded together with the disk between them.

The combined cover sections 9' and H may be regarded as constituting a two-part end flap which is joined to the remaining portion of the cover member along the fold line 25, and when the folding up of the cover sections 9, II and I2 has been accomplished the disk is securely maintained in its mounted, operative position, with a segment of its periphery projecting through the slot 21 and with the numbers contained in each of its number rows I8 and I9 positioned for being displayed one at a time through the sight opening l1. After the user has kept tally from unity to 50 by turning the disk as required and then observing the numerals in the outer row I9, then he or she will observe the numerals of the inner row [8 for tallying from 51 to 100-. A glance at the partly used up ration book will enable the user to determine without difficulty which of the two rows of numbers is to be consulted to determine the number of ration points which have been used.

The cover sections II and I2 are shown as being of substantially equal widths, but the diskcarrying flap 9 is preferably slightly tapered from its attached to its free edge, as shown in Fig. 3.

The window section I I is furnished at each side of the cover structure with a relatively narrow infoldable fiap 28, these flaps each being shown symmetrically positioned in relation to the said section I! and not quite as long as the width thereof. When the cover structure is in its folded up condition these narrow flaps form abutments between which the disk I0 turnably fits, the envelope structure thus provided being completed by adhesive applied to the faces of the flaps 28 opposite to that shown in Fig. 3.

In Figs. 5, 6 and '7 is shown another embodiment of the invention wherein a case or wallet adapted to contain ration books is'combined with the number disk. In these views the construction of the disk In is the same as that already described and therefore the various parts thereof are numbered in the same manner. In the completed article an end flap 30 to which the disk is pivoted, is folded so as to be adjacent to the inner side of the window section 31. When the article is open as shown in Figs. and 6 said window section forms the front outer wall thereof, and the middle section 32, of which said section 3| is a continuation, forms the back wall of the wallet. From the opposite edge of the section 32 extends a section 33 that carries a flap 34, thus forming a pocket 35.

The completed article shown in Figs. 5 and 6 has a stitched on selvage strip 36 along each end section 3|.

I thus completing a pocket 3'! back of the number disk, as well as the already mentioned pocket 35. Along the free edge portion of the end flap 34 is shown an inwardly folded flap 38 which is stitched down to form a selvage.

In Fig. '7, where the one-piece wall member of the wallet is separately shown in a partly folded condition, the ivot-forming fingers 40 are shown in their unbent condition, these same fingers appearing in Fig. 6 in their bent over position forming a pivot for the disk l0 and being retained in their bent over position by the overlying wall In this view are shown a slot 4| and a sight opening 42 which function the same as the slot 21 and sight opening I! already described.

It will be seen most readily in Fig. 6 that when the article is in its completed condition, the pocket 31 has a front wall which is free from any internal projection, whereas, if the indicating disk were furnished witha pivot forming eyelet an end of such eyelet would necessarily project into the pocket in an objectionable manner.

It will be seen that, in both illustrated embodiments of the invention, one of the pivot-forming fingers is positioned at that side of the pivotforming structure which is nearest to the slot through which an edge portion of the indicating disk projects, so that such finger will receive, in a direct and flatwise manner, the pressure against the disk produced by the manual turning thereof. Hence the disk may be so mounted that the edge portion thereof opposite to its projecting segment is kept out of frictional contact with the casing or wallet.

It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents which fall within the scope of the subject matter claimed.

What is claimed is:

1. The combination, with a disk having a centrally apertured portion; of a mounting member for said disk carrying a plurality of fingers or ears which extend through the aperture of said disk and are outwardly directed from a common center to overlie the portion of the disk circumjacent to its aperture to attach said disk pivotally to said member, said mounting member consisting of a semi-rigid sheet material and said lingers being integral therewith; and a supporting member of which said mounting member is a continu ation and against which it is foldable to a position wherein said fingers are interposed between said two members and are thus maintained in their pivot'forming relation to said disk, said supporting member and said mounting member invisibly enclosing between them said pivot fingers when the device is in the completed condition.

2. In a device of the kind described, a cover member consisting of semi-rigid sheet material and having an end flap which is foldable upon it, a plurality of fingers carried by said fiap,'said fingers being grouped around and directed radially outward from a common center which is located at a point spaced considerably inward from edge portions of said flap, and a disk having a central aperture through which said fingers extend to form a pivot upon which said disk is rotatable, said flap and cover member being foldable along a fold line between them into a juxtaposed postion wherein the cover member engages said fingers to keep them in a deflected pivot forming condition.

3. In a ration point tally, a cover member consisting of a strip of semi-rigid sheet material and having a two-part end flap joined thereto along a transversely extending fold line, the two parts of said end flap being joined by a fold line for folding upon each other, and means to maintain said flap in said folded over position, said cover member having a plurality of fingers consisting of portions of the sheet material thereof, said fingers being bent over and directed outwardly from a common center and said disk having a central, pivot aperture through which said fingers eXtend to pivotally attach the disk to the cover member, said fingers being maintained in a bent over pivot-forming position by reason of the constricted space which they occupy between said flap and the remaining portion of said cover member.
