. 1 V This invention relates to improvementsin spectacle cases, and is more particularly directed to a spectacle case of a structure and made pursu ant to the method hereinafter set forth. Spectacle cases, such as thosetowhich the instant invention relates, comprise a pocket portion defined by front and rear walls secured together at theirlongitudinal ends and bottom, the rear wall being extended to define a flap which may be folded over the front wall and secured thereto by glove fastener or other latching means.
As the flap is folded over the front wall and constitutes an extension of the rear wall, it was customary to make the spectacle case of flexible material. While flexibility is desirable for permitting the flap to be folded over the front wall, it is undesirable from the standpoint that a flexible pocket affords little or no protection for the spectacles contained therein.
Pursuant to my invention, the spectacle case is provided with a front wall made of substantially rigid material. At the same time, the flap portion of the case is flexibly connected to the rear wall. Thus, on the one hand, I have provided the pocket portion of the spectacle case with a substantially rigid front wall which provides a high degree of sturdiness to the case and protection to the contained spectacles, and, at the same time, I have provided a rear wall havin a flap which may be folded over the front wall in the customary manner. I have attained this objective in a novel fashion, which will permit manufacture of spectacle cases in a facile manner and at low cost.
These and other advantageous objects, which will appear from the drawings and from the description hereinafter, are accomplished by the structure and method of my invention, of which an embodiment is illustrated in the drawings. It will be apparent, from a consideration of said drawings, and the following description, that the invention may be embodied in other forms suggested thereby. Such other forms as come within the scope of the appended claims are to be considered within the scope and purview of the instant invention.
In the drawings: 7
Fig. 1 is a plan view of the blank of flexible material which defines the rear wall and flap of the spectacle case made pursuant to my invention.
Fig. 2 is a similar view of the blank from which the front wall of the spectacle case is made,
Fig. 3 is a schematic, fragmentary, sectional view illustrating the manner in which the ends and bottom of the front wall blank are deformed, for a purpose presently described,
Fig. 4 is a horizontal, sectional View, taken me-' dially of a front wall blank deformed pursuant to the method indicated schematically in Fig. 3,
Fig. 5 is a fragmentary, sectional view illustrating the manner in'which the marginally flanged portion of the front wall blank is sewed to the rear wall blank to complete the spectacle case,
Fig. 6 is an elevational view of a spectacle case made in accordance with my invention, and
Fig. 7 is a top plan View thereof, taken on line L-l of Fig. 6.
As shown in the drawings, the spectacle case embodying my invention comprises a front wall blank l0 having comparatively rigid, inflexible characteristics, and a rear wall blank ll of relatively flexible characteristics, said rear wall having an extension defining a flap l2. The line In in Fig. 1 indicates the usual folding line of the blank I! in closing the spectacle case. The front wall is initially, as will be noted from-Fig. 2, of greater length than the rear wall blank I l and is likewise of greater height than the rear wall blank measured to line I2a thereof. Said front and rear Wall blanks are secured together to define the pocket P of the spectacle case S for the reception of the spectacles, positioned on the block B in said pocket. The spectacle case may be closed by complementary fastener elements or in any other desired convenient manner. It will be understood that the specific outline of the spectacle case and the block and fastening means shown herein are illustrative only.
The front wall blank I0 is made of comparatively heavy, rigid material, such as relatively inflexible sheets of leather, while the blank which defines the rear wall is made of flexible leather or other material. Said blanks are initially cut, as shown in Figs. 1 and 2, to form a spectacle case of the outline shown in Fig. 6. It will be understood that by suitably altering the outline of said blanks, a finished spectacle case of correspondingly altered outline maybe produced. The front wall blank [0 is positioned between dies 20 and 2| to deform the ends I3, I4 and bottom of the blank to define a relatively narrow marginal flange 23 and shouldered portion 24 contiguous thereto, to thus offset the front wall proper with respect to the rear wall and the bottom and end edges of the blank [0, defining the pocket P of the spectacle case. The blanks 20 and 2! may be heated to facilitate the deforming operation. The illustration in Fig. 3 of the method of deforming the ends and bottom of the front wall blank is suggestive only. The same end may be attained by use of other expedients. The front wall blank so deformed is then superimposed upon the rear wall blank and is sewed thereto by stitches passed through the marginal flange 23 and through the corresponding rear wall. If desired, instead of sewing the blanks together, the marginal flange of the front wall blank may be glued, stapled, or otherwise united with or secured to the rear wall blank.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
1. A spectacle case made of a pair of separate blanks, one of which is comparatively inflexible, said blank being deformed along the ends and bottom thereof to define a marginal flange and a blanks, one of which is comparatively inflexible,
said blank being deformed along the ends and bottom thereof to define a marginal flange and a shouldered portion contiguous thereto, the said blanks being secured together marginally.
3. The method of making a spectacle case from an inflexible front wall blank and a rear Wall blank, comprising deforming the front wall blank to define a marginal flange at the ends and bottom thereof and a shouldered portion contiguous thereto, superimposing said front wall blank on the rear wall blank, and stitching the marginal 4 flange of the front wall blank to the rear wall blank.
4. The method of making a spectacle case from an inflexible front wall blank and a rear wall blank, comprising deforming the front wall blank to define a marginal flange at the ends and bottom thereof and a shouldered portion contiguous thereto, superimposing said front wall blank on the rear wall blank, and securing said blanks together marginally.
5. The method of making a spectacle case from an inflexible front wall blank and a rear wall blank, comprising positioning the front wall blank between complementary deforming dies, applying pressure to the dies, to deform the blank to define a marginal flange at the ends and bottom thereof and shouldered portion contiguous thereto, superimposin said front wall blank on the rear wall blank, and securing said 26 blanks together marginally.
