Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
79 words
A soaking pit cover for use with a soaking pit, said cover comprising: a cover plate having a bottom surface; spaced holding means connected to and depending from the bottom surface of said plate; and, flexible insulating material connected to and disposed in the spaces between said spaced holding means to form an insulating surface adjacent substantially the entire bottom surface of said cover whereby the bottom surface of said cover plate is substantially lined with said insulating material.
Claim 2
Dependent Claim
79 words
A soaking pit cover for use with a soaking pit, said cover comprising: a cover plate having a bottom surface; spaced holding means connected to and depending from the bottom surface of said plate; and, flexible insulating material connected to and disposed in the spaces between said spaced holding means to form an insulating surface adjacent substantially the entire bottom surface of said cover whereby the bottom surface of said cover plate is substantially lined with said insulating material.
Claim 3
Dependent Claim
45 words
A soaking pit cover in accordance with claim 1 wherein: said holding means includes means for joining said insulating material to said holding means; and, said insulating material comprises flexible strips of material, said insulating strips being adapted to be attached to said holding means.
Claim 4
Dependent Claim
22 words
A soaking pit cover in accordance with claim 2 wherein said holding means are strips and said joining means are spike-like members.
Claim 5
Dependent Claim
53 words
A soaking pit cover in accordance with claim 3 wherein said holding means are metal strips having a plurality of spike-like members projecting outwardly from said metal strips, and said strips of insulating material are disposed on said spikes sufficient to form an insulating surface adjacent the bottom surface of said cover plate.
Claim 6
Dependent Claim
70 words
A soaking pit cover for use with a soaking pit, said cover comprising: a cover plate having top and bottom surfaces; a plurality of spaced strips depending from and attached to said bottom surface; said strips having a plurality of spike-like members projecting outwardly therefrom; a plurality of flexible strips of insulating material disposed on said members whereby an insulating cover is formed adjacent the bottom surface of said cover.
Claim 7
Dependent Claim
70 words
A soaking pit cover for use with a soaking pit, said cover comprising: a cover plate having top and bottom surfaces; a plurality of spaced strips depending from and attached to said bottom surface; said strips having a plurality of spike-like members projecting outwardly therefrom; a plurality of flexible strips of insulating material disposed on said members whereby an insulating cover is formed adjacent the bottom surface of said cover.
Claim 8
Dependent Claim
20 words
A soaking pit cover in accordance with claim 5 wherein said depending strips are metal and said members are spikes.
Claim 9
Independent Claim
94 words
The method of making a soaking pit cover according to the steps of: attaching a first strip having spike-like members projecting therefrom to a soaking pit cover plate; installing at least one strip of flexible insulating material on said spike-like members and compressing said material against said strip whereby air spaces are substantially obviated; and installing a second strip of material having spike-like members projecting therefrom adjacent said compressed flexible material while said strips are maintained in a compressed position so that said second strip will retain said insulating material in a compressed state.
Claim 10
Independent Claim
94 words
The method of making a soaking pit cover according to the steps of: attaching a first strip having spike-like members projecting therefrom to a soaking pit cover plate; installing at least one strip of flexible insulating material on said spike-like members and compressing said material against said strip whereby air spaces are substantially obviated; and installing a second strip of material having spike-like members projecting therefrom adjacent said compressed flexible material while said strips are maintained in a compressed position so that said second strip will retain said insulating material in a compressed state.
Claim 11
Dependent Claim
53 words
The method of making a soaking pit cover in accordance with claim 7 wherein the steps of attaching strips of material having spike-like members projecting therefrom to said cover plate and installing said strips of insulating material are repeated until an insulating cover is located adjacent the bottom surface of said cover plate.
Claim 12
Dependent Claim
54 words
The method of making a soaking pit cover in accordance with claim 7 wherein a plurality of strips of flexible insulating material are disposed on said members and said strips of insulating material are maintained in a compressed position while said second strip is attached to maintain said insulating material in a compressed position.
