Abstract
Abstract Irrigating apparatus including an improved valve is provided. The valve includes a two-piece shaft construction which is low in cost and can readily replace an existing valve in an irrigating system. The valve is employed in each of a plurality of outlet pipes communicating with a manifold supply pipe containing the irrigating water. The valve has transversely-extending, elongate, handles which are manipulatable by a T-wrench. Through the Twrench, the valve can be remotely operated so that one need not stoop over to open, close, or adjust the valve. The transverse handles are located both above and below the outlet pipe to enable it to be used on either side of the manifold pipe, so that a single pipe section can be used for discharging water in either direction from the manifold.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
281 words
Irrigating apparatus comprising a manifold, a plurality of outlet pipes spaced along said manifold, communicating therewith, and extending outwardly therefrom for discharging water from said manifold, a valve for each of said outlet pipes having a flat valve body within the corresponding outlet pipe and having shaftreceiving means receiving shaft means extending generally vertically through the outlet pipe in both upper and lower directions, said valve body being pivotable between an open position and a shut position, said shaft means comprising a first shaft having a first portion extending part way through said shaft-receiving means of said valve body, said first shaft also extending outwardly through a wall of the pipe and having a second, transversely-extending portion outside said pipe, bent away from said first portion and extending in one direction therefrom, a second shaft having a first portion extending part way through said shaft-receiving means of said valve body, said second shaft also extending outwardly through the wall of said pipe diametrically opposite said first shaft, said second shaft having a second, transversely-extending portion outside said pipe, bent away from the first portion of said second shaft and extending in one direction therefrom, said second portions of said first and said second shafts extending in a common direction and being parallel to one another and to said flat valve body, inner ends of said first portions of said first shaft and said second shaft having interengaging means cooperating with one another to prevent one shaft from turning relative to the other shaft but not to prevent movement of said shafts in opposite directions away from one another, and means for affixing said first and second shafts to said valve body.

Claim 3
Dependent Claim
228 words
Irrigating apparatus including a pipe of circular transverse cross section, a valve structure for said pipe comprising a generally flat valve body having a passage extending diametrically therethrough and having openings on a common side thereof to receive first and second fasteners, a first shaft having a portion extending part way through said passage and having means to receive a first fastener extending through said valve body into said passage, said first shaft also extending outwardly through a wall of said pipe and having a transversely-extending portion outside said pipe, a second shaft having a portioN extending part way through said passage and having means to receive a second fastener extending through said body into said passage, said second shaft also extending outwardly through the wall of said pipe diametrically opposite said first shaft, said second shaft having a transversely-extending portion outside said pipe, said transversely-extending portions of said first and said second shaft being parallel to each other and parallel to said flat valve body, inner ends of said shafts in said passages having offsets cooperating with one another to prevent one shaft from turning relative to the other but not to prevent movement of said shafts in opposite directions away from one another, and first and second fasteners extending through said valve body openings and into the receiving means of said first and said second shafts.
