Abstract
Abstract A combined fastener and tension indicator means employed for securing the ends of a band having undulations formed therein. The band is employed for retaining insulation panels which have been applied over the exterior surface of a structure to be insulated thereby. The structure to be insulated is caused to expand and/or contract depending upon the surrounding atmospheric conditions. A tension is applied to the band to insure the band always being in close contact with the exterior surface of the structure to which the panels have been applied. The undulations formed in the band together with the amount of tension applied to the band will permit for the structure to which the panels have been applied to expand and/or contract while still retaining the insulation panels in close contact with the exterior surface of the structure to which the panels have been applied.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
121 words
In a method of retaining insulating panels in close intimate contact with the exterior surface to which the panels have been applied and wherein said structure is subjected to expansion and contraction due to atmospheric conditions surrounding said structure, the improvement comprising retaining said panels against the outer surface of said structure by means of an encircling band having undulations formed therein throughout substantially the length thereof with the ends of the said band sucured to a spring loaded fastener and tension indicator means, said undulated band enabling said structure to expand and contract dependent upon surrounding atmospheric conditions while still retaining said panels in close intimate contact with the outer surface of the structure to which they have been applied.
Claim 2
Dependent Claim
121 words
In a method of retaining insulating panels in close intimate contact with the exterior surface to which the panels have been applied and wherein said structure is subjected to expansion and contraction due to atmospheric conditions surrounding said structure, the improvement comprising retaining said panels against the outer surface of said structure by means of an encircling band having undulations formed therein throughout substantially the length thereof with the ends of the said band sucured to a spring loaded fastener and tension indicator means, said undulated band enabling said structure to expand and contract dependent upon surrounding atmospheric conditions while still retaining said panels in close intimate contact with the outer surface of the structure to which they have been applied.
Claim 3
Dependent Claim
43 words
The method recited in claim 1 wherein said panels are arranged in horizontally extending rows on said structure and wherein the next adjacent row of panels placed on said structure is in staggered relationship with respect to a previously arranged row of panels.
Claim 4
Dependent Claim
40 words
The method recited in claim 1 wherein the tension on the bands may be varied to compensate for the expansion and contraction of the structure to which they have been applied depending upon the varying temperature conditions surrounding said structure.
Claim 5
Dependent Claim
163 words
A combined fastener and tension indicator means for maintaining an undulated band in constant contact with the exterior surface of insulation panels which have been applied to the exterior surface of the structure to be insulated thereby and wherein said structure is subjected to expansion and contraction depending upon the atmospheric conditions, the improvement comprising said band provided with a plurality of undulations formed therein to thus present high portions and valleys therebetween, the ends of said band being secured to a fastener and tension indicator, means on said fastener and tension indicator to vary the amount of tension applied to said band the tension applied to said band causing said valleys to remain in constant contact with the exterior surface of the said panels and to exert a force thereon to thus maintain said insulation panels in close contact with the exterior surface of the structure to which the panels have been applied notwithstanding the expansion and contraction of the said structure.
Claim 6
Dependent Claim
163 words
A combined fastener and tension indicator means for maintaining an undulated band in constant contact with the exterior surface of insulation panels which have been applied to the exterior surface of the structure to be insulated thereby and wherein said structure is subjected to expansion and contraction depending upon the atmospheric conditions, the improvement comprising said band provided with a plurality of undulations formed therein to thus present high portions and valleys therebetween, the ends of said band being secured to a fastener and tension indicator, means on said fastener and tension indicator to vary the amount of tension applied to said band the tension applied to said band causing said valleys to remain in constant contact with the exterior surface of the said panels and to exert a force thereon to thus maintain said insulation panels in close contact with the exterior surface of the structure to which the panels have been applied notwithstanding the expansion and contraction of the said structure.
Claim 7
Dependent Claim
19 words
The structure recited in claim 4 wherein a tension spring is housed is said fastener and tension indicator means.
Claim 8
Dependent Claim
32 words
The structure recited in claim 4 wherein a pawl and ratchet and rotatable spool assembly is employed to vary the amount of tension applied to the said band through the aforesaid spring.
Claim 9
Dependent Claim
88 words
The structure recited in claim 4 wherein said combined fastener and tension indicator is mounted on an anchor plate engaging with the outer surface of the structure to which the insulating panels are applied, said anchor plate having an opening formed therein to receive one end of the said band with means to secure said band to said anchor plate, an extension adjustably secured to said fastener and tension indicator at the other end of said anchor plate to which the other end of said band is secured.
Claim 10
Dependent Claim
169 words
A combined fastener and tension indicator means for maintaining a band having undulations formed therein in constant contact with the exterior surface of insulation panels which have been applied to the exterior surface of a structure to be insulated thereby, said structure expanding and contracting depending upon the surrounding atmospheric conditions, said fastener and tension indicator comprising a housing having an anchor plate fixed thereto with means at one end thereof for securing said band thereto, an externally threaded rod extending through said housing, a spring encircling said rod and an adjustment nut mounted on said threaded rod and abutting one end of said spring, the other end of said spring abutting a bulkhead bushing on said housing, said rod extending beyond said housing and secured to an anchor plate, said anchor plate provided with means whereby the other end of said band is secured to said anchor plate, said housing provided with a slot therein whereby the amount of tension applied to the said band can be ascertained.
Claim 11
Dependent Claim
169 words
A combined fastener and tension indicator means for maintaining a band having undulations formed therein in constant contact with the exterior surface of insulation panels which have been applied to the exterior surface of a structure to be insulated thereby, said structure expanding and contracting depending upon the surrounding atmospheric conditions, said fastener and tension indicator comprising a housing having an anchor plate fixed thereto with means at one end thereof for securing said band thereto, an externally threaded rod extending through said housing, a spring encircling said rod and an adjustment nut mounted on said threaded rod and abutting one end of said spring, the other end of said spring abutting a bulkhead bushing on said housing, said rod extending beyond said housing and secured to an anchor plate, said anchor plate provided with means whereby the other end of said band is secured to said anchor plate, said housing provided with a slot therein whereby the amount of tension applied to the said band can be ascertained.
