:4 iii Z 0% 9" @Z Patented Apr. 7, 1931 UNITED STATES ALBERT w. ENGEL, OF. CHICAGO, ILLINOIS CORNER-POCKET-MOUNTING nEvIoE Application filed June 2, 1928 Serial No. 282,469.

The purpose of this invention is to provide an improved device for securing photographs, pictures, cards and the like, to a suitable mounting, in a convenient and artlstic mans ner, especially when the object to be mounted is provided with a substantialmargin or brder. It consists in certain features of construction as herein shown and described, and as indicated by the claims.

In the drawings:

Figure 1, is a plan view showing a picture provided with my improved corner mounting device, ready to be secured to a suitable mounting. V

1 Figure 2 is a detail view of the device unattached, indicating in dotted lines, the manner of producing the same in quantities.

Figure 3 is a view of the reverse slde of a portion of a picture with a corner pocket 29 mounting applied thereto, the gummed areas being indicated by stippling.

In the drawings, 1, indicates a picture to be mounted, provided at its corners with the improved corner mounting devices, 2, which are of a somewhat, irregular outline, as shown in Figure 2. The mounting device is formed from a single piece of material such as cloth or paper and is gummed on one side for securement to a mount. An angular slit is pro- 30 vided in the mounting device, comprising two I slit portions, 3, connected at their ends at ap proximately right angles with the apex on the longitudinal center line of the device. The ends of the slit portions, 3, connect with terminal slit portions, 4, extending outwardly at right angles thereto These terminal slit portions, 4, preferably, though not necessarily, are connected to the adjacent slits, 3, by curved portions, ,5, so as to provide an at- 4O tractive appearance as the slit forms the outline of the portion of the device that is visible on the face side of the picture when finally mounted. Flap portions, 6, for engaging'the reverse side of the marginor edges of the object to be mounted, are formed by score lines, 7, extending from the center of the upper edge, 8, to the lateral edges, 9, parallel with the slits, 3, and communicating with the ends of the terminal slit portions, 4. These flaps are preferably cut to have edges, 10, ex-

tending parallel to the score lines, 7. The width of the flap may be approximately the same as the distance between the slits 3, and the adjacent score lines 7. l

It will be understood that the portion of the device other than the right angle-area, 1 1, (bounded by slits, 3, 4 and score lines, 7), and the fiaps, 6, may be of any suitable shape, but for simplicity and economy in fabrication, the outline of the loweredge of the remaining portion between the sides, 9, is of similar contour to that formed by the respective edges, 10, 8, 10. This outline provides projecting ears, 12, for securing the object to a mounting sheet or board. As indicated in Figure 2, these corner mounting devices may be cut from a strip of material whose width is the desired width of the device determined by the distance between the lateral edges, 9. Further, this manner of forming the devices, eliminates all waste and permits economical production.

When a picture or the like is to be mounted, the corner mounting device, 2, is moistened on the gummed side, and the picture corner is 5 inserted through the slits with the gummed side of the device opposite the face side of the picture, and with the adjacent lateral edges of the picture, aligning with the respective score lines, 7. The angular portion, 11, 8O bounded by slits, 3, 4 and score lines, 7 then being disposed over the face side of the picture, becomes adhesively secured thereto. The flaps, 6, which are bent on the score lines, or are folded back and secured partially to the reverse side of the picture and to some extent to the gummed sidejof the device. These flaps when folded back, form a pocket, and thus insure proper seating on the corner of the picture or card when it is inserted through the slit. As the flaps, 6, are folded back,'it will be seen that the two portions of former Y edge, 8, lie parallel to and adjacent each other.

It is not essential that the corner pocket mounting to be effective must have the angular portion, 11, adhesively secured to the face side of the object to be mounted, but, on the contrary, the flaps 6, may be first folded back, then the corner of the object inserted into the slits, 3; then only the remaining gummed surface needs be moistened for securing to a suitable mountlng. This arrangement permits the removal of the picture or card from the mounting devices, when desired. Also,

5 it is to be noted that a pocket so constructed obviates tearing of the slits of the mounting device by constant insertion and extraction oi the object. a

I claim 2- 1. A corner pocket of sheet material gummed on one side and having an angular slit With transverse terminal portions extending away from the enclosed angle of the slit, and having marginal areas doubled over toward the gummed surface by folding along lines respectively parallel to the main portions of the slit.

2. A picture mounting device comprising a fitting of sheet material gummed on one side and having an area, a part of which is adapted to fit closely over the corner of a card or picture to be mounted with the gummed surface against the card, and having marginal portions folded to fit over the intersecting edges of such card or picture adjacent its corner to engage its under surface, said area having a slit dividing it into the said part which fits over the corner of the card and another part which extends under the card so for adhesive securement to a mounting sheet.
