Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
160 words
A balancing assembly for controlling the diversion of water in a channel comprising; dam means positioned in a channel means, the top surface of said dam means including a depression adapted to receive an opening spill segment, pivot means permitting pivotal movement of said dam relative to said channel means, seal means depending from the perimeter of said dam means for bearing against said channel means when said dam means is in the closed position, control means for pivoting said dam means, attachment means secured to said dam means for attaching said control means thereto, said attachment means permitting relative movement between said control means and said dam, one extremity of said control means extending downwardly from said attachment means to bear against the channel means for support and another extremity of said control means extending upwardly from said attachment means to permit the actuation of said control means to selectively space said dam means apart from the channel means.
Claim 2
Dependent Claim
160 words
A balancing assembly for controlling the diversion of water in a channel comprising; dam means positioned in a channel means, the top surface of said dam means including a depression adapted to receive an opening spill segment, pivot means permitting pivotal movement of said dam relative to said channel means, seal means depending from the perimeter of said dam means for bearing against said channel means when said dam means is in the closed position, control means for pivoting said dam means, attachment means secured to said dam means for attaching said control means thereto, said attachment means permitting relative movement between said control means and said dam, one extremity of said control means extending downwardly from said attachment means to bear against the channel means for support and another extremity of said control means extending upwardly from said attachment means to permit the actuation of said control means to selectively space said dam means apart from the channel means.
Claim 3
Dependent Claim
34 words
The balancing assembly of claim 1 Wherein said pivot means includes a cutaway socket means secured to said dam means and disposed for selective engagement with a corresponding ball means depending from the channel.
Claim 4
Dependent Claim
31 words
the balancing assembly of claim 1 with said dam disposed to stop against a node means depending from the channel to prevent wedging of said dam means in the closed position.
Claim 5
Dependent Claim
19 words
The structure of claim 3 wherein said seal means is bonded to the perimeter surface of said dam means.
Claim 6
Dependent Claim
37 words
The balancing assembly of claim 1 with said control means extends through a perforation in said dam means, said control means and said attachment means having frictional telescoping movement selectively spacing said dam apart from the channel.
Claim 7
Dependent Claim
44 words
The structure of claim 5 wherein said attachment means is a tube means superimposing a dam perforate means and said control means extends therethrough bearing against the channel for support and in frictional telescoping movement therewith selectively spacing said dam apart from the channel.
Claim 8
Dependent Claim
42 words
The balancing assembly of claim 1 wherein said attachment means is a swivel means and the downward extension of said control means being an offset means bearing the channel for support while in selective position spacing said dam apart from the channel.
Claim 9
Dependent Claim
43 words
The balancing assembly of claim 1 including a spill segment being in pawled pivotal engagement with said dam and including intermediate catch means maintaining the closing thereof, catch linkage means cooperating with a float activator means for the release of said spill segment.
Claim 10
Dependent Claim
28 words
The structure of claim 8 wherein the float activator means is a bucket activator means cooperating with the spill of water for the release of said spill segment.
Claim 11
Dependent Claim
15 words
The structure of claim 8 wherein the float activator means is a solenoid activator means.
Claim 12
Dependent Claim
67 words
The balancing assembly of claim 1 including spill segment and spill segment actuation means comprising; a support member depending from the face of the dam, movable lever arm means in mechanical advantage interconnecting said spill segment and said support while including rearward extension, a counterweight selectively locating along said rearward extension, a float means attaching said lever arm disposed to buoy the actuation of said spill segment.
Claim 13
Dependent Claim
143 words
The structure of claim 11 including dual float means and being further characterized by a holding means cooperating with said dual float means for leveling the actuation of said spill segment comprising; elongate perforate means in said lever arm means permitting said dual float means limited vertical travel, a follower means depending from said support member to cage float travel and including opposite extremity upper and lower finger portions depending from said follower means, movable catch means depending from said support member to selectively hold said spill segment closed, a spring means interconnecting said catch means and said lower finger, said spring means becoming loaded by the movement of said float, movable trip means depending from said support member to hold said catch means and maintaining spill segment closure until impacted by said upper finger for the release thereof buoyed by said float.
Claim 14
Dependent Claim
125 words
The balancing assembly of claim 1 including a spill segment and spill segment actuation means comprising; float means disposed upstream of said dam means, a trough means aligned with the spill segment lip to thereby become weighted by water to initiate the opening thereof, trough perforate means being provided to leak and dissipate the weight of water, upstream support members depending from the face of said dam, movable lever arm means in mechanical advantage having intermediate engagement with said upstream support members while interconnecting said trough means and said float means, downstream support members depending from said dam, segment extension means in mechanical advantage having intermediate pivotal engagement with said downstream suPports while interconnecting said spill segment and said lever arm for the actuation thereof.
