Abstract

Abstract This invention is a counterbalancing assembly for air motivated devices such as windmills, for use in pumping water or other liquids from wells. The assembly includes arms extending outwardly from opposite sides of the reciprocating lifting rod of the windmill. The arms are affixed to rotatable discs, each of which is provided with a flexible member secured to the disc periphery and extending to a cross member secured to the lifting rod and movable therewith. In order to counterbalance the weight of the lifting rod and the material being pumped, the arms of the assembly are constructed of telescopic sections to increase or decrease the arm length to effect the desired leverage.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 151 words
A counterbalancing assembly for air motivated devices having a tower, a windwheel mounted atop the tower and a reciprocating lifting rod disposed within the tower, the assembly including: a. a cross arm extending transversely of, and fixedly connected at approximately its midpoint to the lifting rod, b. members roTatably mounted on said tower on opposite sides of the lifting rod, c. flexible members connected at one end to said cross arm, d. the opposite end of said flexible members being engaged with said members for rotating the latter, e. arms fixed to each of said members and movable therewith, f. said arms extending outwardly from said members and said lifting rod, g. whereby said arms counterbalance the weight of said lifting rod and liquid being lifted, to maintain the lifting rod in a partially lifted position in the event the windmill ceases operation during the pump stroke of the lifting rod.
Claim 2
Dependent Claim 151 words
A counterbalancing assembly for air motivated devices having a tower, a windwheel mounted atop the tower and a reciprocating lifting rod disposed within the tower, the assembly including: a. a cross arm extending transversely of, and fixedly connected at approximately its midpoint to the lifting rod, b. members roTatably mounted on said tower on opposite sides of the lifting rod, c. flexible members connected at one end to said cross arm, d. the opposite end of said flexible members being engaged with said members for rotating the latter, e. arms fixed to each of said members and movable therewith, f. said arms extending outwardly from said members and said lifting rod, g. whereby said arms counterbalance the weight of said lifting rod and liquid being lifted, to maintain the lifting rod in a partially lifted position in the event the windmill ceases operation during the pump stroke of the lifting rod.
Claim 3
Dependent Claim 12 words
The counterbalancing assembly of claim 1, wherein: a. said arms are extensible.
Claim 4
Dependent Claim 25 words
The counterbalancing assembly of claim 2, wherein: a. said arms include telescopic sections, and b. means for maintaining said arm sections in predetermined relative position.
Claim 5
Dependent Claim 19 words
The counterbalancing assembly of claim 3, wherein: a. at least one of said telescopic sections includes a weighting material.
Claim 6
Dependent Claim 26 words
The counterbalancing assembly of claim 1, wherein: a. said members include discs, and b. said discs are provided with annular recesses to receive said flexible members.
Claim 7
Dependent Claim 160 words
A counterbalancing assembly for an air motivated device having a tower, a windwheel mounted atop the tower and a reciprocating lifting rod disposed within the tower, the assembly including: a. a cross arm extending transversely of, and fixedly connected at approximately its midpoint to the lifting rod, b. members having arcuate portions rotatably mounted on said tower, c. flexible members connected at one end to said cross arm, d. said flexible members being trained over the periphery of said arcuate portions, e. the other end of said flexible members being fixed to said members, f. elongated arms secured to said members, g. said elongated arms extending outwardly from said members and said lifting rod, h. said arms being extensible, i. whereby said arms counterbalance the weight to said lifting rod and liquid being lifted, to maintain the lifting rod in a partially lifted position in the event that the windmill ceases operation during the pump stroke of the lifting rod.
Claim 8
Dependent Claim 160 words
A counterbalancing assembly for an air motivated device having a tower, a windwheel mounted atop the tower and a reciprocating lifting rod disposed within the tower, the assembly including: a. a cross arm extending transversely of, and fixedly connected at approximately its midpoint to the lifting rod, b. members having arcuate portions rotatably mounted on said tower, c. flexible members connected at one end to said cross arm, d. said flexible members being trained over the periphery of said arcuate portions, e. the other end of said flexible members being fixed to said members, f. elongated arms secured to said members, g. said elongated arms extending outwardly from said members and said lifting rod, h. said arms being extensible, i. whereby said arms counterbalance the weight to said lifting rod and liquid being lifted, to maintain the lifting rod in a partially lifted position in the event that the windmill ceases operation during the pump stroke of the lifting rod.
Claim 9
Dependent Claim 30 words
The counterbalancing assembly of claim 6, wherein: a. said extensible arms comprise a plurality of telescopic arm sections, and b. means for retaining said arm sections in predetermined relative position.
Claim 10
Dependent Claim 21 words
The counterbalancing assembly of claim 7, with the addition of: a. weighting material within at least one of said telescopic sections.
