Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
252 words
In an apparatus for automatically venting gases accumulated above a liquid responsive to the to open of the liquid which apparatus comprises a chamber adapted to hold liquid and gas, conduit means below the liquid level in said chamber connecting said liquid and gas to a source thereof, float means within said chamber disposed for reciprocating movement relative to the level of liqud in said chamber, vent means above the liquid level in said chamber adapted to vent gas therefrom close biased valve means operatively associated with said vent means responsive to the level of said float means adapted to close said vent means upon the rise of said liquid level and corresponding movement of said float means and adapted to open said vent means upon the lowering of said liquid level and corresponding movement of said float means, and a junction member attaching said float means to said valve means; the improvement which comprises said junction member comprising two prong means extending from said valve means, a bent first portion extending from said float means engaging a first of said prong means in the bend thereof whereby said bent portion depresses said first prong means upon lowering said liquid level and permitting said bias to close said valve upon rising of the liquid level, and a straight second portion extending from said float means slidably engaging a second of said prong means whereby said float means is substantially prevented from rotational motion relative to said valve means and to said chamber.
Claim 2
Dependent Claim
252 words
In an apparatus for automatically venting gases accumulated above a liquid responsive to the to open of the liquid which apparatus comprises a chamber adapted to hold liquid and gas, conduit means below the liquid level in said chamber connecting said liquid and gas to a source thereof, float means within said chamber disposed for reciprocating movement relative to the level of liqud in said chamber, vent means above the liquid level in said chamber adapted to vent gas therefrom close biased valve means operatively associated with said vent means responsive to the level of said float means adapted to close said vent means upon the rise of said liquid level and corresponding movement of said float means and adapted to open said vent means upon the lowering of said liquid level and corresponding movement of said float means, and a junction member attaching said float means to said valve means; the improvement which comprises said junction member comprising two prong means extending from said valve means, a bent first portion extending from said float means engaging a first of said prong means in the bend thereof whereby said bent portion depresses said first prong means upon lowering said liquid level and permitting said bias to close said valve upon rising of the liquid level, and a straight second portion extending from said float means slidably engaging a second of said prong means whereby said float means is substantially prevented from rotational motion relative to said valve means and to said chamber.
Claim 3
Dependent Claim
92 words
The improvement according to claim 1 including a valve body having a tubular edges seat member disposed for communication with the interior of the chamber and defining a venting passage through the valve body, a resilient closure member disposed in operative engagement with the tubular edged sheet member to effectively open and close the venting passage, and spring means operatively connected to the closure member operatively connected with the valve body for urging the closure member into a normal position of operative engagement with the seat member to close the vent passage.
Claim 4
Dependent Claim
40 words
T8e improvement according to claim 1 wherein said float means contains a multiple of projecting extensions for resting the float means at the bottom of said chamber in the absence of buoyant engagement of said float means with the liquid.
Claim 5
Dependent Claim
59 words
The improvement according to claim 3 including means for guiding comprising a rod extending from the bottom of the float member and slidably engaging the conduit means whereby restraining the float member from lateral movement during reciprocating movement caused by buoyant engagement with the liquid within the chamber entering the chamber through the conduit means from the liquid source.
Claim 6
Dependent Claim
47 words
The improved apparatus claimed in claim 1 wherein said second portion is longer than the distance from the top of said chamber to the bottom of said valve means whereby said second portion prevents said float from contacting said valve means upon the rising of said liquid.
