Abstract
Abstract A gauge glass protector includes an annular grommet carried by a frustro-conical skirt and an inverted collector rim at the circumference of the skirt. A drainage hole for condensate is located at the juncture of the collector rim and the conical skirt for draining the collected liquid out of the trough formed between the skirt and the rim. The same device may be used as an aerosol mist collector by inverting it. In another embodiment of the invention the skirt may comprise a semi-circular flexible collar which when assembled has a frustro-conical shape. Another embodiment calls for a spiral wire attached to the sight gauge including a conical run-off trough at the point where the wire is tangential to the gauge.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
171 words
A gauge glass protector apparatus for protecting the vertical gauge glass on a boiler type of liquid containing pressure vessel, said apparatus comprising: a grommet means for frictionally engaging said gauge glass and holding said apparatus in place against said gauge glass; a downwardly sloping skirt means for directing liquid away from said gauge glass, said downwardly sloping skirt means being attached to said grommet means; an upwardly sloping rim connected around the edge of said downwardly sloping skirt means at a juncture, said upwardly sloping rim forming a collector trough between said rim and said downwardly sloping skirt means; and a collector trough drainage hole means located substantially at the juncture between said upwardly sloping rim and said dowardly sloping skirt means, wherein liquid travelling down said vertical glass gauge impinges upon said grommet means and is carried away from the area of said glass gauge by said downwardly sloping skirt means and into said collector though at which location said liquid harmlessly passes through said trough drainage hole means.
Claim 2
Dependent Claim
171 words
A gauge glass protector apparatus for protecting the vertical gauge glass on a boiler type of liquid containing pressure vessel, said apparatus comprising: a grommet means for frictionally engaging said gauge glass and holding said apparatus in place against said gauge glass; a downwardly sloping skirt means for directing liquid away from said gauge glass, said downwardly sloping skirt means being attached to said grommet means; an upwardly sloping rim connected around the edge of said downwardly sloping skirt means at a juncture, said upwardly sloping rim forming a collector trough between said rim and said downwardly sloping skirt means; and a collector trough drainage hole means located substantially at the juncture between said upwardly sloping rim and said dowardly sloping skirt means, wherein liquid travelling down said vertical glass gauge impinges upon said grommet means and is carried away from the area of said glass gauge by said downwardly sloping skirt means and into said collector though at which location said liquid harmlessly passes through said trough drainage hole means.
Claim 3
Dependent Claim
38 words
The glass gauge protector apparatus of claim 1 further including: a drip wire means connected to said apparatus and passing through said drainage hole means for providing specific direction for the liquid passing through said drainage hole means.
Claim 4
Dependent Claim
26 words
The apparatus of claim 2 wherein said grommet means includes a first surface which is tapered to slope in the same direction as the skirt means.
Claim 5
Dependent Claim
26 words
The apparatus of claim 3 wherein said grommet means further includes a second surface tapered to slope in substantially the same direction as said first surface.
Claim 6
Dependent Claim
18 words
The apparatus of claim 4 wherein said skirt means and said collector rim comprise an aluminum like material.
Claim 7
Dependent Claim
32 words
The apparatus of claim 5 wherein said grommet means comprises a temperature and corrosion resistant rubber-like material having an inside diameter just slightly less than the outside diameter of the gauge glass.
Claim 8
Dependent Claim
19 words
The apparatus of claim 6 wherein said grommet means includes a circular groove therein for receiving said skirt means.
