TRANSPARENT MOUNTING CORNER Filed March 23, 1953 Patented Jan. 26, 1937 UNITED STATES PATENT OFFICE 9 Claims.

The purpose of this invention is to provide an improved mounting device in the form of a pocket for securing photographs, pictures, cards and the like to any suitable mount in a convenient, artistic manner, with the corners of the card or picture inserted in the pockets which constitute the invention, and with said pockets adhesively afiixed to the mount. Another object is to provide a mounting pocket of this character which shall be transparent, and therefore substantially invisible, so that it shall not obscure any portion of the picture which it overlies. A further object is to adapt a pocket of this character for securing the card or picture either temporarily and removably, or permanently, at the option of the user. Another object is to permit the construction of the transparent portion of the pocket of celluloid or cellophane or like material, while combining therewith a fibrous material such as paper, which may be rendered adhesive more reliably than the transparent material.

In the drawing:

Figure 1 illustrates a grouping of the three elements which constitute one form of the mounting corner, showing them in disassembled relation.

Figure 2 is a perspective view of the completed corner on a larger scale.

Figure 3 is a. fragmentary view of a picture or the like as secured to a mount by means of a mounting corner of the type shown in Figure 2.

Figure 4 is a detail section taken as indicated at line 44 on Figure 3.

Figure 5 illustrates a grouping of three elements which constitute a modified form of the corner, and which are shown in disassembled relation.

Figure 6 is a perspective view of a finished corner made from the elements shown in Figure 5.

Figure 7 illustrates a grouping of two elements adapted to form a modification of the preceding corners.

Figure 8 is a perspective view showing said two elements assembled into a finished mounting corner.

Figure 10 shows a finished corner composed of the two elements of Figure 9 with the backing member secured to the inner surface of the flaps of the pocket member.

Figure 11 shows a finished corner composed of the two elements of Figure 9 with the backing member secured to the outer surface of the flaps of the pocket member.

Figure 12 illustrates still another modification composed of two elements shown in disassembled relation.

Figure 13 shows the parts of Figure 12 assembled with the backing member secured to the outer surfaces of the flaps.

Figure 14 is a perspective view of a corner comprising three elements, namely, a pocket member with folded flaps and two similar backing memcars like the one shown in Figure 12.

This application represents a further development of the invention to which my Patent No. 1,913,110, issued June 6, 1933, is directed. In fact, Figures 1 to 8 of the drawing herein illustrate structures similar to those shown in said patent.

The desirability of using transparent material for a pocket mounting corner is obvious; it is almost invisible in use, because the portion of the picture, or any printed matter on the sheet which is secured in position thereby, shows through the transparent material overlapping the corner of such sheet. When the transparent portion of such a corner is made from sheet material folded into form, it is desirable to add an adhesive'member to complete the pocket, and also to carry the gum which may be moistened for rendering the pocket adhesive to a mounting surface when it is put in use.

Figure 1 shows such a pocket composed of three elements, namely, a triangular sheet of paper, I, preferably gummed on both sides, a formed corner pocket of the transparent material, seen at 2, and a second triangular sheet of paper, 3, also shown gummed on both sides. The member, I, forms the bottom layer of the assembled pocket. The under flaps, 4, 4, of the transparent member, 2, are secured to the upper gummed surface of said member, I, and the third member, 3, is inserted in the pocket, so that its under gummed surface is adhesively secured to the upper or inner surfaces of the flaps, 4, and to the portion of the upper surface of the member, I, which is exposed at the space or opening formed between the inner outlines of the flaps, 4.

The finished corner is shown in Figure 3, and it will be seen that the notch formed at 2 in the continuous triangular area of the transparent upper wall, will facilitate entering the corner of a sheet or card in the pocket. If it is desired to secure such sheet permanently in the pocket, the sheet itself may be moistened on its under surface before insertion, and then as it is entered in the pocket, it may be pressed against the upwardly exposed gummed surface of the part, 3, to which it will adhere. The upper surface of the card or picture, 5, will be visible clearly through the transparent material, 2, of the pocket, as seen in Figure 3. The adhesive on the under side of the member, I, will serve for attaching the pocket to a mounting surface. Figure 3 represents a fragment of such a mount at 6, with the corner portion of a picture or card, 5, secured in a pocket indicated at 2, in the usual position for such use. The relation of the parts is clearly indicated in section in Figure 4.

If celluloid or cellophane is employed as the material of the pocket member, 2, the adhesive used on members, I and 3, may be such as will form an effective bond with the transparent material. However, to further ensure the permanency of this connection, the flaps, 4, are formed with terminal portions adjacent the open side of the pocket, which are wider than the remainder of the fiaps, so that the inner outline of each flap is angular, and the space between them at the open edge of the pocket is narrower than at a point remote from said edge. Thus the areas of the fibrous members, I and 3, which are adhesively secured to each other, are inter-locked with these angular fiaps against withdrawal in the direction of the open edge of the pocket; hence, even if the adhesive should not hold perfectly between the cellophane or celluloid and the fibrous members, this inter-locking arrangement will serve to hold the parts in their assembled relation.

A feature of my present structure is that the fibrous triangular members, I and 3, are slightly smaller than the triangular outline of the transparent member, 2, so that when the parts are assembled, the folded marginal portions, I, of the finished pocket, are outside the outlines of the opaque members, I and 3, and when a card or picture, such as that indicated at 5 in Figure 3, is inserted in such a pocket, the paper parts, I and 3, are completely hidden under the card, 4. This feature is of especial advantage in mounting postage stamps or other articles having serrated edges which are thus completely accommodated in the transparent marginal portions, I, of the pocket, with the paper parts, I and 3, wholly covered by the solid area of the stamp. The result is a very neat effect, owing to the unobtrusive character of the mounting pocket.

Figures 5 and 6 illustrate a modification in which the three-ply lower wall of the corner projects beyond the upper transparent wall, 20, at the hypotenuse, 2i, of said upper wall, to facilitate entering the corner of the card or picture which is to be mounted. In this construction the hypotenuse, 2i, is not notched as in the form shown in Figure 1, since the function of the notch, 2 shown in Figure 1, is to be performed by the projection of the lower wall beyond the hypotenuse in this modified style. The transparent portion of the pocket includes flaps, 40, folded under the upper wall, 20, and formed with notched inner edges to secure an inter-locking effect with the triangular paper members, III and 30, when the parts are assembled.

Figure 7 shows a slight modification from the structure of Figures 1 to 4, in which a single piece of material is substituted for the triangles, I and 3. It may be a substantially square sheet folded along its diagonal, I5, to form triangular halves, II and I5, so that these two halves may be assembled against opposite surfaces of the flaps, 4, 4, of the transparent corner member, 2. This arrangement may simplify the process of assembly, and will slightly strengthen the construction, at the same time giving the finished article a somewhat neater appearance, because the folded edge, I5, will replace the three-ply edge of the construction shown in Figures 1 to 4, as will be clear from Figure 8.

Figure 9 shows the unassembled parts of a pocket corner composed of two elements instead of three, comprising the transparent corner element, 2, and a single triangular element, l6, of fibrous material, such as paper or textile gummed on both sides. The gum employed is such as to form a firm and permanent bond with the transparent material of the member, 2, and the triangle, I5, may be secured either to the inner surface of the flaps, 4, as shown in Figure 10, or it maybe fastened to the outer surface of said flaps, 4, as seen in Figure 11. With the arrangement of Figure 10 a part of the gummed area is exposed outwardly through the spaces between the edges of the flaps, 4, and will serve for securing the pocket to a mount such as that shown at 6 in Figure 3. This leaves the entire upper gummed surface available for fastening the picture into the pocket, if desired. With the parts assembled as shown in Figure 11, a portion of the upper area of the part, I6, is exposed in the spaces between the edges of the flaps, l, 5, while the entire lower area is available for attaching the pocket to the mount.

Figure 12 illustrates a two-part construction comprising a transparent pocket member, 5!), and a fibrous member, 89, which may be understood as gummed on both sides. The pocket member is similar to the member, 2, of Figure 1, except in two particulars. Its upper triangular area has no notch cut in its hypotenuse. Instead, the gummed member, 68, of fibrous material, is formed with a notch, GI, and this member is assembled with the pocket member, Ell, so that the notched edge is substantially flush with the straight edge, 5!, of the pocket. And the flaps. 54, instead of terminating parallel with the edge, 5I, are cut back slantingly with respect thereto. The fibrous member, 60, may be adhesively secured to the under surfaces of the flaps, 54, as in Figure 13. Or, if desired, two similar members, indicated at 62 and 63 in Figure 14, may be secured to opposite faces of the flaps, 5 3, forming a three-piece structure in which, at the open side of the pocket, one edge is the straight edge, 5|, of transparent material, and the other edge is a two-ply edge of paper, or the like, the two layers being bonded directly to each other by reason of the slanted formation of the ends of flaps, 54. The members, 62 and 63, are both notched at 6V.

With the devices of Figures 13 and 1 the corner of the card or picture to be mounted is inserted in the pocket by registering it first in the notch, SI or 6 I and pressing it upwardly against the overlapping transparent area of the pocket member, 50, thus forcing the pocket open sufficiently to receive the corner of the picture. As shown in the drawing, notched members, 60, 62 and 63 may be made smaller in area than the outer face of the pocket member, 50, so that their edges shall be set back from the folded edges of the pocket members, thus leaving completely transparent marginal portions of the pocket for a purpose already made clear in the description of the preceding forms of my invention.

The precise method of manufacture has not been described herein, but there are several ways in which the parts may be assembled, either by hand or by automatic machinery. Furthermore, it may be understood that the fibrous or paper elements, I and 3, I0 and 39, II-I3, I8, 60, 62 and 63, of the several constructions herein described, may be double-gummed stock, that is, sheet material which has been previously coated on both sides with a gum which only requires moistening to make it adhesive; but doublegummed stock is not essential, since the two opposed faces of the fibrous members, I and 3, or the corresponding parts of the other structures,

may have a gum or mucilage applied to them in the process of assembly, in which case the stock need be previously gummed only on one surface, which is to be moistened by the user in mounting the pocket or in securing the picture or card therein.

While there is shown and described herein certain specific structure embodying this invention, it will be manifest to those skilled in the art that various modifications and re-arrangements of the parts may be made without departing from the spirit and the scope of the invention, and that the same is not limited to the particular form herein shown and described, except in so far as indicated by the appended claims.

I claim:

1. A mounting pocket comprising a top wall of transparent sheet material with flaps of said material folded thereunder and along two sides of the pocket, together with a layer of fibrous sheet material adhesively secured to said flaps, tying them together to form the bottom wall of the pocket, said bottom wall having a notch in its edge at the open side of the pocket and the top wall overlying the area of said notch.

2. A mounting pocket of right-triangular form comprising a top wall of transparent sheet material with portions of said material folded thereunder along the two legs of the triangular outline, and a layer of fibrous sheet material adhesively secured to said portions connecting them and forming the back wall of the pocket, said back wall being also of right-triangular outline and except for a right-angled notch formed in its edge at the open side of the pocket and under the area of the top wall with the sides of said notch substantially parallel to the legs of the triangular outline.

3. A mounting pocket comprising a triangular top wall of transparent sheet material with flaps of said material folded under and along two sides of the triangle, leaving a relatively wide space between their edges under said top wall, and a layer of fibrous sheet material gummed on both sides and adhesively secured to the under surfaces of said flaps with a portion of its upper surface exposed toward the top wall through said space between the edges of the flaps, said bottom Wall having a notch in its edge at the open side of the pocket and disposed under the area of the top wall.

4. A mounting pocket comprising a triangular top wall with flaps integral with it at two sides folded toward each other under said top wall and having respectively at their inner ends terminals which project toward each other forming back of said terminals recesses in the oppositely facing edges of the flaps, and a layer of gummed fibrous fabric material adhesively secured to said flaps extending across the gap between said recessed facing edges with its gummed surface exposed through said gap for adhesion to a mount, whereby when the pocket is mounted, the fibrous fabric sheet exposed through the gap and adhering to the mount locks the flaps and thereby the top wall of the pocket to the mount against edgewise withdrawal.

5. A mounting pocket comprising a top wall of transparent sheet material with flaps of said material folded under and along two sides of the pocket which are substantially at right angles to each other, leaving a relatively wide space between the edges of said flaps under the top wall, and a layer of gummed fibrous sheet material adhesively secured to said flaps and extending across the space between their edges to form a bottom wall for the pocket with a portion of its gummed surface exposed in said space, said bottom wall having a notch in its edge at the open side of the pocket and disposed under the area of the top wall.

6. A mounting pocket comprising a triangular top wall of transparent sheet material with flaps of said material folded under and along two sides of the triangle, leaving a relatively wide space between their edges under said top wall, and a layer of fibrous sheet material gummed on both sides and adhesively secured to the inner surface of said flaps with a portion of its gummed surface exposed outwardly through the space between their edges.

'7. A mounting pocket composed of a top wall of transparent sheet material with flaps of said material folded under and along two sides of the pocket and having respectively, at their inner ends, terminals which project toward each other, forming, back of said terminals, recesses in the oppositely facing edges of the flaps, and a single layer of gummed fibrous sheet material adhesively secured to said flaps extending across the gap between said recessed facing edges with its gummed surface exposed through said gap for adhesive attachment to the surface of another element with which the pocket is to be employed, whereby such attachment locks the flaps and thereby the top wall of the pocket against edgewise withdrawal.

8. A mounting pocket composed of a top wall of transparent sheet material with fiaps of said material folded under and along two sides of the pocket and having respectively, at their inner ends, terminals which project toward each other, forming, back of said terminals, recesses in the oppositely facing edges of the flaps, and a single layer of gummed fibrous sheet material adhesively secured to said flaps extending across the gap between said recessed facing edges with its gummed surface exposed through said gap for adhesive attachment to the corner of a picture card or the like when the latter is inserted in the pocket, whereby such attachment locks the fiaps and thereby the top wall of the pocket against edgewise withdrawal.

9. A mounting pocket composed of a top wall of transparent sheet material having two edges at right angles along which the material is folded under itself in the form of flaps providing space for the insertion of a picture card or the like with its edges stopped by said folds, the card being entered at the open edge of the pocket opposite the right angle formed by said folds, said flaps forming a relatively large opening between their opposite edges under the top wall, said opening having greater width as measured at a distance fro-m the open edge of the pocket than it has adjacent said edge, and a single layer of gummed fibrous material adhesively secured to said flaps extending across the opening between them with its gummed surface exposed through said opening for adhesive attachment to a surface when the pocket is placed in service.
