Claim 1
Independent Claim
209 words
For use in a metal roofing system of the batten type, a series of pan sections, each formed of a simple piece of prefolded sheet metal having an elongated central region and two parallel upstanding side walls, a first of said upstanding side walls extending upwardly at right angles to the central region of the pan section and then outwardly in a plane parallel to the central region of the pan section, and the second of said upstanding side walls extending upwardly at right angles to said central region, outwardly parallel to said central region and then downwardly a distance short of the plane of the central region of the pan section to form a hollow partial rectangle and then folded back on itself to lie against the upwardly, outwardly and downwardly extended portions to form double walls of the second upstanding side wall, a terminal portion of the sheet metal forming the said second side wall being extended outwardly from the upwardly extending portion of the second side wall in the plane of the central region of the pan section beyond the downwardly extending portion of the second side wall to form a narrow margin to receive fasteners for holding the pan sections to an underlying roof structure.

For use in a metal roofing system of the batten type, a series of pan sections, each formed of a simple piece of prefolded sheet metal having an elongated central region and two parallel upstanding side walls, a first of said upstanding side walls extending upwardly at right angles to the central region of the pan section and then outwardly in a plane parallel to the central region of the pan section, and the second of said upstanding side walls extending upwardly at right angles to said central region, outwardly parallel to said central region and then downwardly a distance short of the plane of the central region of the pan section to form a hollow partial rectangle and then folded back on itself to lie against the upwardly, outwardly and downwardly extended portions to form double walls of the second upstanding side wall, a terminal portion of the sheet metal forming the said second side wall being extended outwardly from the upwardly extending portion of the second side wall in the plane of the central region of the pan section beyond the downwardly extending portion of the second side wall to form a narrow margin to receive fasteners for holding the pan sections to an underlying roof structure.
Claim 3
Dependent Claim
102 words
For use in a metal roofing system as set forth in claim 1 a series of pan sections in which said terminal portion of the sheet metal is folded upwards upon itself to form an upstanding longitudinal stop, the said stop being located within the batten structure adjacent to and parallel with the downwardly extending portion of the said second side wall, the said downwardly extending portion of the second wall and the said stop together holding the said first side wall of an adjacent interengaged pan section vertical and parallel with the upwardly extended portion of the said second side wall.
Claim 4
Dependent Claim
110 words
For use in a sheet metal roofing system as set forth in claim 2, a series of pan sections in which the overall width dimension of the said first wall of the pan section is slightly less than the internal width dimension of the said second wall for longitudinal sliding fit of the said first side wall of one pan section within the said second side wall of an adjacent pan section and between its downwardly extending portion and the said stop such that the upwardly extending portion of the first side wall is disposed inwardly of the downwardly extending portion of the second sidewall and outwardly of said stop.
Claim 5
Dependent Claim
64 words
For use in a sheet metal roofing system as set forth in claim 1, a series of pan sections in which the outwardly extending portion of the first upstanding side wall is folded downwards at right angles to lie parallel with and against the inner surface of the upwardly extending double wall of the second upstanding side wall of an adjacent interengaged second section.
Claim 6
Dependent Claim
59 words
For use in a sheet metal roofing system as set forth in claim 1, a series of pan sections in which the outwardly extending portion of the said second side wall is extended longitudinally beyond the ends of the formed battens and is foldable downwardly and inwardly to form a closure to the open end of a formed batten.
