A, w’ ENG'E; TRANSPARENT MOUNTING CORNER ‘ Filed March 23, 1953 ' 2,068,909 Patented Jan. 26, 1937 2,068,909 UNITED STATES PATENT OFFICE 2,068,909 TRANSPARENT MOUNTING CORNER Albert W. Engel, Chicago, 111. Application March 23, 1933, Serial No. 662,231 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 in vention, and with said pockets adhesively a?ixed to the mount. Another object is to provide a mounting pocket of this character which shall be 10 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 remov 15 ably, 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 ?brous material ‘such as paper, which 20 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 mount 25 ing 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 30 mounting corner of the type shown in Figure 2. Figure 4 is a detail section taken as indicated at line 4—4 on Figure 3. Figure 5 illustrates a grouping of three elements which constitute a modi?ed form of the corner, and which are shown in disassembled relation. Figure 6 is a perspective view of a ?nished corner made from the elements shown in Figure 5. Figure 7 illustrates a grouping of two elements adapted to form a modi?cation of the preceding corners. Figure 8 is a perspective view showing said two elements assembled into a ?nished mounting corner. Figure 9 illustrates a further modi?ed con 45 struction consisting of two elements shown in disassembled relation. Figure 10 shows a ?nished corner composed of the two elements of Figure 9 with the backing member secured to the inner surface of the flaps 50 of the pocket member. Figure 11 shows a ?nished 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 modi?cation 55 composed of two elements shown in disassembled relation. Figure 13 shows the parts of Figure 12 assem bled with the backing member secured to the outer 80 surfaces of the ?aps. (Cl. 40-158) Figure 14 is a perspective view of a corner com prising three elements, namely, a pocket member with folded ?aps and two similar backing mem ‘cars like the one shown in Figure 12. This application represents a further develop ment 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 por tion of such a corner is made from sheet material folded into form, it is desirable to add an ad hesive'member to complete the pocket, and also to carry the gum which may be moistened for rendering the pocket adhesive to a mounting sur face 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 mate rial, 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 as sembled pocket. 10 15 20 25 The under ?aps, 4, 4, of the 30 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 se cured to the upper or inner surfaces of the flaps, 35 4, and to the portion of the upper surface of the member, I, which is exposed at the space or open ing formed between the inner outlines of the ?aps, 4. The ?nished corner is shown in Figure 3, and it will be seen that the notch formed at 211 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, 45 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 up wardly exposed gummed surface of the part, 3, to which it will adhere. The upper surface of the 50 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 repre 55 sents 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 in dicated in section in Figure 4. 60 2 2,068,909 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 ma terial. However, to further ensure the perma nency 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 ?aps, so that the inner outline of each ?ap is angular, and the space between them at the open edge of the pocket is narrower than at a on both sides. The gum employed is such as to form a ?rm and permanent bond with the trans parent material of the member, 2, and the tri angle, I5, may be secured either to the inner sur face 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 ex posed 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 point remote from said edge. Thus the areas of the ?brous members, I and 3, which are adhe sively secured to each other, are inter-locked with 15 these angular ?aps against withdrawal in the direction of the open edge of the pocket; hence, even if the adhesive should not hold perfectly be in Figure 3. This leaves the entire upper gummed surface available for fastening the picture into tween the cellophane or celluloid and the ?brous the entire lower area is available for attaching members, this inter-locking arrangement will the pocket to the mount. Figure 12 illustrates a two-part construction 20 comprising a transparent pocket member, 5!), and a ?brous member, 89, which may be understood serve to hold the parts in their assembled rela tion. A feature of my present structure is that the ?brous triangular members, I and 3, are slightly smaller than the triangular outline of the trans parent member, 2, so that when the parts are assembled, the folded marginal portions, ‘I, of the the pocket, if desired. With the parts as sembled 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, ll, 5, while 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 25 no notch cut in its hypotenuse. Instead, the ?nished pocket, are outside the outlines of the gummed member, 68, of ?brous material, is opaque members, I and 3, and when a card or formed with a notch, GI, and this member is as picture, such as that indicated at 5 in Figure 3, sembled with the pocket member, Ell, so that the notched edge is substantially flush with the 30 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 mount ing postage stamps or other articles having ser rated edges which are thus completely accom modated 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 modi?cation in which the three-ply lower wall of the corner 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 ?brous member, 60, may be adhesively se cured 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 se cured to opposite faces of the ?aps, 5L3, forming a three-piece structure in which, at the open side of the pocket, one edge is the straight edge, 40 5|, of transparent material, and the other edge projects beyond the upper transparent wall, 20, at the hypotenuse, 2i, of said upper wall, to is a two-ply edge of paper, or the like, the two facilitate entering the corner of the card or pic ture which is to be mounted. In this construc tion the hypotenuse, 2i, is not notched as in the form shown in Figure 1, since the function of the notch, 21*, shown in Figure 1, is to be per formed by the projection of the lower wall be yond the hypotenuse in this modi?ed style. The reason of the slanted formation of the ends of layers being bonded directly to each other by flaps, 54. The members, 62 and 63, are both 45 notched at 6V‘. With the devices of Figures 13 and 14., the cor ner of the card or picture to be mounted is in transparent portion of the pocket includes flaps, 40, folded under the upper wall, 20, and formed serted in the pocket by registering it first in the notch, SI or 6 Ia, and pressing it upwardly against 50. the overlapping transparent area of the pocket member, 50, thus forcing the pocket open suffi with notched inner edges to secure an inter-lock ciently to receive the corner of the picture. ing effect with the triangular paper members, III and 30, when the parts are assembled. Figure 7 shows a slight modi?cation from the structure of Figures 1 to 4, in which a single piece of material is substituted for the triangles, shown in the drawing, notched members, 60, 62 I and 3. It may be a substantially square sheet 60 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 con struction, at the same time giving the ?nished 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 As and 63 may be made smaller in area than the 55 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 60 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 ?brous or paper elements, I and 3, I0 and 39, II-I3, I8, 60, 62 and 63, of the several constructions herein de scribed, may be double-gummed stock, that is, sheet material which has been previously coated 70 on both sides with a gum which only requires ment, 2, and a single triangular element, l6, of moistening to make it adhesive; but double gummed stock is not essential, since the two op posed faces of the ?brous members, I and 3, or 15 ?brous material, such as paper or textile gummed the corresponding parts of the other structures, pocket corner composed of two elements instead of three, comprising the transparent corner ele 2,068,909 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 cer tain speci?c structure embodying this invention, it will be manifest to those skilled in the art that 10 various modi?cations 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 15 indicated by the appended claims.
