United States Patent This invention relates: to wallets or billfolds of the type which are provided with auxiliary gusset pockets.

One of the objects of the present invention is to provide a wallet or billfold, of the above indicated type, I

made partly or entirely of non-heat-sealable material, for example, leather, which has the gussets of the auxiliary pocket secured to a wall of the wallet or billfold with heat-sealed means.

A further object is to provide a wallet or billfold hav- I log an auxiliary gusset pocket made of non-heat-sealable material with the gussets of the pocket secured to the wallet with heat-sealed means, other parts of the wallet being made partly'or entirely of material which is also non heat-sealable.

Another object of this invention is to facilitate the manufacture of wallets of the gusset pocket type by providing a construction which enables the gusset pocket to beattached to the wallet by simple and convenient assem bly and Securing operations.

Another object is generally to provide a wallet or billfold of the above indicated type having improved means for securing the gussets of the auxiliary pocket to a wall of the billfold, said billfold being made of heatsealable material or non-heat-sealable material or a combination of both.

The above and other objects, features and advantages of this invention will be fully understood from the following description considered in connection with the accompanying illustrative drawings of the presently preferred embodiment of this invention.

FIG. 2. is a perspective view of part of the billfold showing the auxiliary gusset pocket in an open and expanded condition;

FIG. 3 is a plan view of a die cut blank of a pocket mlsctlnber in flat condition before it is attached to the bill- FIG. 4 is a perspective rear view of part of the billfold, with parts omitted, illustrating an intermediate step in securing the auxiliary gusset pocket to a wall member of the billfold;

FIG. 5 is a view similar to FIG. 4, with portions cut away, showing the gusset pocket secured to the wall member of the billfold;

FIG. 6 is a sectional view taken on line 6-6 of FIG. 2, on a slightly larger scale;

FIG. 7 is a sectional view taken on line 7-7 of FIG. 2, on a slightly larger scale;

FIG. 8 is an exploded perspective view of part of a billfold, in accordance with another embodiment of the invention, illustrating the parts in a disassembled condition;

FIG. 9' is a perspective view similar to FIG. 8 with the parts in an intermediate condition of assembly;

FIG. 10 is a view similar to FIG. 9, with the parts shown in their assembled condition; and

FIG. 11 is a sectional view taken on line 11-11 of FIG. 10.

Referring now to the drawings in detail, the billfold 10 may be of any usual or conventional construction and includes the main bill compartment defined by the outer wall 12 and the inner wall 14 which includes a "ice folded over wall 16, the bills being disposed between said folded over wall 16 and outer wall 12. A conven tional compartment 18 is provided between folded over wall 16 and inner wall 14 and part of said inner wall 14 constitutes a front wall member 20 for compartment 18., to which is secured an'auxiliary gusset pocket 22 formed from a blank 22A, illustrated in FIG. 3.

In the embodiment of the invention illustrated in FIGS. 1-7, the billfold is made partly of heat-scalable material and partly of non-heat-sealable material, although it will be understood that the. billfold may be made entirely of heat-scalable material or material coated with a heat-sealable material. More particularly, the outer wall .12, the gusset pocket 22, and the foldable closure member or flap 24 are made from a non-heat-sealable material, for example leather, which enhancesthe appearance of the billfold and provides better wearing material for those parts of the billfold subject to excessive wear. The remaining parts of the billfold, including the front wall member 20 of the compartment, are made of heat-sealable material, for example,.vinyl sheet plastic'material or cloth or paper having on one surface thereof a coating of vinyl plastic or other heat-scalable material. As will be clearly seen hereinafter, the heat scalable surface of wall member 20 is used for securing the pocket 22 to said wall member with heat-sealed means. a a

As illustrated in FIG. 3, the blank 22A for forming the auxiliary gusset pocket 22 includes the part 26 which constitutes the front wall of the pocket and the foldable parts 2'8, 30 at-each side edge of said front wall to provide the gussets 32 of the pocket, as best shown in FIGS. 2 and 5.

The blank 22A is also provided with the integral end parts 34 which have tongue extensions 36 with end slits 38. It will be understood that the blank 22A is formed in one integral piece, being die cut to the outline illustrated by FIG. 3, or to any other suitable outline according to variations which maybe made in the details of the form and construction of the pocket pursuant to the present invention. Flap 24 and front wall 26 of the pocket are preferably provided with companion releasable fasteners, here shown as snap fasteners 40 and 42', for releasably securing. said flap=24 in closed position.

The wall member 20 is provided with foldable end portions 44, as best seen in FIGS. 4 and 5, each of said end portions being provided with a slit 46. As shown in FIGS. 2 and 4, to secure the pocket 22 to wall member 20, the lower edge 48 of the front Wall 26 of the pocket is secured, by stitching 50, to the lower edge of wall member 20 and the extensions 36 of the pocket are inserted in the slits 46 of end portions 44 and extend in over-lapping surface-to-surface contact with said end portions, at the rear surfaces thereof, as shown. The slits 38 provide an interlock for the extensions 36 with the adjacent parts of end portions 44 at the slits 46, which will be readily understood. It will also be noted that the extensions 36 are inserted in said slits 46 at the front of wall member 20 while the end portions 44 are lying in their flat unfolded positions. I

The end portions are folded over against the rear surface of wall member 20 so that extensions 36 are disposed between said rear surface and said folded over end portions 44 with the heat-scalable surfaces of said folded over portions facing the rear or main Wall 12 of the billfold. If desired, the folded over end portions may be temporarily secured intheir folded condition by cementing the front surfaces thereof to the rear surface of wall member 20, which need not be a heatsealable surface. A sheet of material or wall member 52, which is made of heat-scalable material or has a heat-scalable coated surface, for example a vinyl plastic coating, is superimposed on the heat-sealable surfaces of said folded over end portions 44 and is heat-sealed to said end portions for securing said end portions in said folded over condition, whereby the extensions 36 are locked in position and the gusset end parts 34 of the pocket are secured to wall member 20, as best seen in FIGS. 5, 6 and 7. The flap 24 of the pocket may be secured to the upper edge of wail member 20, as by stitching 54.

The manner in which the heat-sealing operation 'is accomplished is believed to be obvious to those skilled in the art. It may be noted that the operation is preferably accomplished while the

main walls

12 and 14 and wall 16 are in a'flat unfolded condition and a metal plate forming one electrode of the di-electric heat-sealing apparatus is inserted in pocket 22 after the extensions 36 are'inserted through the'slits 46 of end portions 44. The opposite side of the 'fiat blank is positioned within a shallow metal tray which'constitutes the other electrode of the di-eleotric heat-sealing apparatus so that the parts of the billfold are in position for the heat-sealing operation. A further detailed description of the heat-sealing operation is not considered necessary asit does not, per se, form part of the invention apart'from the construction of the gusset pocket 22 and the heat-sealing operation for securing the pocket to wall member 20.

It will be understood, as mentioned above, that billfold may be made entirely of heat-scalable material, for example paper 'orcloth coated with vinyl plastic. In such case the extensions 36 will not only be locked in position between folded over ,portions 44 and the rear surface of wall member 20, but also the heat-scalable surfaces of said extensions 36 will "be heat-sealed to the heat-scalable surfaces of said folded over portions with which they are in surface'contact.

Referring now to FIGS. 8 through lltof the drawings, there is shown another embodiment of .the invention wherein -a billfold 10A is..made entirely of non-heat-sealable material, for example leather. ,InFIGr 8, the pocket 22 is shown secured. at'its lower edge to the front surface of-wall member 20, 'at'thelower edge thereof, by stitching 50, asprevi'ously described. Asheet of material or wall member 56, having a main portion .58, and foldable end portions 60, provided with slots 62 is adhesively secured to the rear-surface of wall member 20 along the front surface of portion 58. The extensions 36 of the gussets are inserted in slots 62, respectively, as best seen in FIG. 9, at the front of wall member 20, and .the end portions 60 are folded over so that the heat-scalable surfaces :of said end portions '60 are in surface-to-surface contact with the heat-sealablesurface of portion 58, as best seen in FIGS. 10 and 11, with extensions 36 being disposed between the confronting heat-scalable surfaces of portion 58 and end portions 60. Said end portions 60are then heat=sealedto portion 58 whereby extensions 36 are secured to wall member 56 and wall member 20. Thus it will be seen that portion 58 constitutes means heat-sealed to said folded over end portions 60 for retaining said end portions in their folded over condition so thatpocket 22 is mounted ,on wall members .20 and 56 of compartment 18. If desired, an additional wall member'64 may be superimposed on folded .wall member 56 and heat-sealed thereto, as shown in FIGS. 10 and 11.
