Abstract

Abstract This invention relates to an improved rain gage based on the old method of the hydraulic water wheel used for power, for centuries, except this is a small precision made water wheel that moves constantly during rainfall in a variation of movement of light to heavy rainfall. The shaft of the water wheel drives three dials of 0 to 1, 1 to 10, 10 to 100 inches, using a knocker system without resetting the dials.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 67 words
A gage for measuring atmospheric precipitation comprising: a trough having an inlet for collecting atmospheric precipitation and an outlet for discharging said precipitation, a water wheel driven by said discharged precipitation, a plurality of dial indicators rotated by said water wheel and slotted sleeve bearings used to mount said wheel and said indicators thereby providing lubrication by said precipitation resulting in uniform friction over an extended period.
Claim 2
Dependent Claim 67 words
A gage for measuring atmospheric precipitation comprising: a trough having an inlet for collecting atmospheric precipitation and an outlet for discharging said precipitation, a water wheel driven by said discharged precipitation, a plurality of dial indicators rotated by said water wheel and slotted sleeve bearings used to mount said wheel and said indicators thereby providing lubrication by said precipitation resulting in uniform friction over an extended period.
Claim 3
Dependent Claim 60 words
The gage of claim 1 further comprising a flange rotated by said water wheel and containing a peg mounted thereon, said dials comprising a first and second dial each having a peg mounted thereon and a third dial, whereby said flange rotates said first dial, said first dial rotates said second dial and said second dial rotates said third dial.
Claim 4
Dependent Claim 21 words
The gage of claim 1 further comprising a hinged screen cover used to protect said dials from birds and blowing debris.
Claim 5
Dependent Claim 43 words
The gage of claim 1 further comprising a housing enclosing said water wheel, said housing containing an inlet defined by said trough and an outlet, said inlet and outlet each containing a screen, thereby preventing insects from hiving or nesting inside said housing.
Claim 6
Dependent Claim 40 words
The gage of claim 1 further comprising a worm gear driven by said water wheel, said dials comprising a first dial driven by said gear, a peg mounted on said first dial and a second dial driven by said peg.
Claim 7
Dependent Claim 34 words
The gage of claim 1 further comprising an optional snow tube connected to said trough, thereby providing a means for collecting snow resulting in rotation of said water wheel upon thawing of said snow.
