Abstract
Abstract A meter reading apparatus includes a telescopic tubular viewer attached to the underground meter and provides a clear sight path through water in the meter box for easy meter reading. In a first embodiment, the viewer member is connected to the meter by a collar, brackets and clamps including a clevis and J-shaped connecting rod. In a second embodiment, the viewer is connected to the meter by a collar integrally formed with the meter and including threads for engaging the viewer. In both embodiments, the viewer is moisture tight and includes a transparent sealing lens at the top end, and an O-ring seal at the bottom end between the viewer and the meter. A coiled air tube may be provided to maintain ambient pressure inside the viewer during extension and retraction.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
131 words
An apparatus providing a clear sight path for reading a meter or the like located in an underground box, comprising: telescopic viewer means having a top end and a bottom end adapted for sealing engagement with the meter; means for connecting said viewer means to said meter; means for sealing said viewer means against the meter so as to prevent water in the meter box from entering and obstructing the sight path through said viewer means; and means for maintaining ambient pressure in said telescopic viewer means as said viewer means is extended and retracted; said telescopic viewer means being moisture tight and extensible to position said top end of said viewer means above any level of water in the meter box thereby allowing visual inspection and reading of the meter.
Claim 2
Independent Claim
131 words
An apparatus providing a clear sight path for reading a meter or the like located in an underground box, comprising: telescopic viewer means having a top end and a bottom end adapted for sealing engagement with the meter; means for connecting said viewer means to said meter; means for sealing said viewer means against the meter so as to prevent water in the meter box from entering and obstructing the sight path through said viewer means; and means for maintaining ambient pressure in said telescopic viewer means as said viewer means is extended and retracted; said telescopic viewer means being moisture tight and extensible to position said top end of said viewer means above any level of water in the meter box thereby allowing visual inspection and reading of the meter.
