Abstract
A pipeline comprises plastic pipe lengths interconnected by plastic couplings with telescoped joints and with plastic valves in each coupling. The pipeline is enclosed and supported by an adjustably suspended sheet metal housing assembly with a charged wire thereon to keep off fowls.
Claims17
In a valve, the combination of:
- walls forming an inlet passage and an outlet passage spaced from each other in a first direction,
- a wall forming a cylinder and having inner and outer ends and having its inner end in communication with the outlet passage and having its outer end opening onto the exterior of the valve, said cylinder extending axially in a second direction transverse to the first direction,
- said cylinder extending across said inlet passage and having a side port in communication with the inlet passage;
- a valve member slidingly mounted in said cylinder for axial movement in said cylinder between an inner closed position closing said side port to cut off the inlet passage and an outer open position uncovering the side port to permit fluid flow from the inlet passage through the side port into the cylinder and out of the inner end of the cylinder into the outlet passage,
- first locking means disposed on the cylinder,
- second means disposed on the cylinder in spaced relationship to the first means in the second direction, and
- third means disposed on the valve member for cooperation with the first means, in a first limit position defined by the second and third means, for locking the third means on the first means in the first limit position and for cooperation with the second means for limiting the sliding movement of the valve member in the second direction to a second limit position.

Apparatus for controlling the flow of fluid through a pipeline for use by fowl, the pipeline having first and second pipes each having an inlet and an outlet, the first pipe being at the upstream end of the pipeline and the second pipe being at the downstream end of the pipeline, including,
- a housing defining a first opening at the outlet side of the first pipe and defining a second opening at the inlet end of the second pipe and defining an axial passage in a direction transverse to the flow of fluid through the pipeline and at a position between the first and second openings,
- a valve member slidable axially with the axial passage in the housing between first and second limit positions and having walls closing the opening in the inlet side of the first pipe in the first position and spaced from the opening in the inlet side of the first pipe in the second position to provide for the passage of fluid through the pipeline in the second position,
- means disposed on the valve member in cooperative relationship with the axial passage in the housing in the first position of the valve member for sealing the housing and the valve member against the flow of fluid in the first position of the valve member,
- first means on the housing member for defining a detent,
- second means disposed on the housing in axially spaced relationship to the first means and defining a shoulder, and
- third means disposed on the valve member and extending externally from the valve member and cooperative with the first means in the first limit position of the valve member for retaining the valve member in the first limit position and cooperative with the second means on the housing member in the second limit position for retaining the valve member in the second limit position.
