Abstract
Abstract This invention relates to the cathodic protection of water storage tanks. In particular, this invention relates to a suspension means for suspending anodes within water storage tanks which is resiliently adjustable in length to permit movement of the anode with respect to the mounting from which it is suspended.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
80 words
In an outdoor water storage tank having cathodic protection means for inhibiting corrosion which includes anode means disposed in the tank, the improvement of anode suspension means having one end rigidly secured to the tank and anode means secured at the other end thereof, and metal coil tension spring means secure to said anode suspension means and disposed intermediate the ends thereof to permit movement of said anode means with respect to said rigidly secured end of said suspension means.
Claim 2
Dependent Claim
80 words
In an outdoor water storage tank having cathodic protection means for inhibiting corrosion which includes anode means disposed in the tank, the improvement of anode suspension means having one end rigidly secured to the tank and anode means secured at the other end thereof, and metal coil tension spring means secure to said anode suspension means and disposed intermediate the ends thereof to permit movement of said anode means with respect to said rigidly secured end of said suspension means.
Claim 3
Dependent Claim
157 words
In an outdoor water storage tank having a cathodic protection means including anode means suspended within the tank, the improvement of suspension means comprising a. anode cable means having one end secured to said anode and the other end rigidly secured to said tank. b. metal coil tension spring means having one end secured with respect to said anode cable at a first point on the length of said anode cable and the other end of said spring means being secured with respect to said cable at a second point on the length of said anode cable which is spaced from the first point along the length of said cable a distance which is substantially greater than the length of said tension spring means whereby said suspension means is adjustable within the range of extension of said spring means to permit movement of said anode means with respect to said tank without overloading said anode cable means.
Claim 4
Dependent Claim
157 words
In an outdoor water storage tank having a cathodic protection means including anode means suspended within the tank, the improvement of suspension means comprising a. anode cable means having one end secured to said anode and the other end rigidly secured to said tank. b. metal coil tension spring means having one end secured with respect to said anode cable at a first point on the length of said anode cable and the other end of said spring means being secured with respect to said cable at a second point on the length of said anode cable which is spaced from the first point along the length of said cable a distance which is substantially greater than the length of said tension spring means whereby said suspension means is adjustable within the range of extension of said spring means to permit movement of said anode means with respect to said tank without overloading said anode cable means.
Claim 5
Dependent Claim
44 words
A water storage tank as claimed in claim 2 wherein said metal tension spring means is entirely disposed above the normal high water level in the tank such that the action of the spring is unaffected by the formation of ice in the tank.
Claim 6
Dependent Claim
53 words
A water storage tank as claimed in claim 2 having an upper wall extending generally transversely thereof, said metal tension spring means being mounted in said tank to extend closely adjacent to and substantially parallel to said upper wall so as to be entirely disposed above the high water level in the tank.
Claim 7
Dependent Claim
166 words
In an outdoor water storage tank having a cathodic protection means including anode means suspended within said tank, the improvement of suspension means for suspending said anode means within said tank comprising a. metal coil tension spring means having a first end and a second end, said first end of said tension spring means being secured with respect to said tank, b. anode cable means having one end secured to said anode means and the other end opening outwardly of said tank adjacent said first end of said tension spring means, c. said second end of said tension spring means being secured to said anode cable means at a point intermediate the ends of said anode cable means, said anode cable means having a length between said point and said other end thereof which is greater than the length of said spring means whereby said spring means may be extended to permit movement of said anode means within said tank without overloading said anode cable means.
Claim 8
Dependent Claim
166 words
In an outdoor water storage tank having a cathodic protection means including anode means suspended within said tank, the improvement of suspension means for suspending said anode means within said tank comprising a. metal coil tension spring means having a first end and a second end, said first end of said tension spring means being secured with respect to said tank, b. anode cable means having one end secured to said anode means and the other end opening outwardly of said tank adjacent said first end of said tension spring means, c. said second end of said tension spring means being secured to said anode cable means at a point intermediate the ends of said anode cable means, said anode cable means having a length between said point and said other end thereof which is greater than the length of said spring means whereby said spring means may be extended to permit movement of said anode means within said tank without overloading said anode cable means.
