Abstract
Abstract A hearth bread baking pan set and method for making same in which a single sheet of material formed to provide an inner structure having multiple baking molds with rib members between adjacent molds is disposed within and secured to an outer structure. The outer structure and rib members cooperate to provide a support structure for the baking molds, spaced therefrom.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
126 words
A baking pan set comprising an inner structure formed from a single rectangular sheet of material to provide multiple baking molds depending from the sheet material and arranged in a row lengthwise of said sheet, rib members formed from the sheet material between adjacent baking molds and depending therefrom downwardly a distance sufficiently to dispose the lowermost portion of said rib members below the bottom walls of the baking molds, outwardly extending flanges formed at the periphery of the sheet material, an outer frame-like structure of rectangular shape having a vertically disposed main body terminating at the upper end thereof in outwardly extending flanges underlying and secured to said inner structure flanges, whereby said inner structure is disposed within and supported by said outer frame-like structure.
Claim 2
Dependent Claim
126 words
A baking pan set comprising an inner structure formed from a single rectangular sheet of material to provide multiple baking molds depending from the sheet material and arranged in a row lengthwise of said sheet, rib members formed from the sheet material between adjacent baking molds and depending therefrom downwardly a distance sufficiently to dispose the lowermost portion of said rib members below the bottom walls of the baking molds, outwardly extending flanges formed at the periphery of the sheet material, an outer frame-like structure of rectangular shape having a vertically disposed main body terminating at the upper end thereof in outwardly extending flanges underlying and secured to said inner structure flanges, whereby said inner structure is disposed within and supported by said outer frame-like structure.
Claim 3
Dependent Claim
49 words
A baking pan set according to claim 1 wherein said rib members are characterized as each having a forming bar entrapped between a folded back portion of the sheet material whereby the rib member has a cross-sectional thickness at least three times the cross-sectional thickness of said sheet material.
Claim 4
Dependent Claim
24 words
A baking pan set according to claim 1 wherein the rib members extend widthwise to abutment with and securement to the frame main body.
Claim 5
Dependent Claim
49 words
A baking pan set according to claim 3 wherein the rib members are characterized as each having a forming bar entrapped between a folded back portion of the sheet material whereby the rib member has a cross-sectional thickness at least three times the cross-sectional thickness of said sheet material.
Claim 6
Dependent Claim
42 words
A baking pan set according to claim 3 wherein the sheet material is light gauge metal having perforations formed in the walls of the baking molds and the frame-like structure is heavy gauge metal having perforations formed in the main body portion.
Claim 7
Dependent Claim
42 words
A baking pan set according to claim 5 wherein the sheet material is light gauge metal having perforations formed in the walls of the baking molds and the frame-like structuure is heavy gauge metal having perforations formed in the main body portion.
Claim 8
Independent Claim
105 words
The method of forming a baking pan set comprising drawing a rectangular sheet of metal material to form baking molds depending therefrom, arranged in side-by-side relation in a single row lengthwise of said sheet, forming outwardly extending flanges at the periphery of the sheet material, deforming portions of the sheet material between adjacent baking molds downwardly to form a multi-thickness rib member extending below the plane defined by the bottom walls of said baking molds, inserting the formed sheet material into a rectangular frame having outwardly extending flanges formed at the top of said frame, and securing the sheet material flanges to the frame flanges.
Claim 9
Independent Claim
105 words
The method of forming a baking pan set comprising drawing a rectangular sheet of metal material to form baking molds depending therefrom, arranged in side-by-side relation in a single row lengthwise of said sheet, forming outwardly extending flanges at the periphery of the sheet material, deforming portions of the sheet material between adjacent baking molds downwardly to form a multi-thickness rib member extending below the plane defined by the bottom walls of said baking molds, inserting the formed sheet material into a rectangular frame having outwardly extending flanges formed at the top of said frame, and securing the sheet material flanges to the frame flanges.
Claim 10
Dependent Claim
21 words
The method of forming a baking pan set according to claim 7 and including securing the rib members to the frame.
