Extendible watering system for fowls

Claim 2

In a valve, the combination of: walls forming an inlet passage and an outlet passage displaced from each other in a first direction; housing means defining, a hollow cylinder disposed in a second direction transverse to the first direction and having a first side port in communication with the inlet passage and having a second port in communication with the outlet passage; a valve member slidingly mounted in said hollow cylinder defined by said housing means for movement between an inner closed position closing said first 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 into the outlet passage, said housing means having an exterior shoulder spaced axially from one end of the hollow cylinder defined by the housing means; latch means extending from the valve member at an end corresponding to the one end of the cylinder and overhanging the cylinder and having construction relative to the exterior shoulder and releasably holding the valve member at its closed position; said shoulder having a circumferential width less than the annular periphery of the hollow cylinder defined by the housing means and said valve member being rotatable in the hollow cylinder to disengage the latch means from said external shoulder by such manual rotation of the valve member, said housing means having a radial shoulder near the axial end of the housing means; and the valve member including means disposed externally of the housing means for engaging said radial shoulder to limit the axial movement of the valve member at the closed position of the valve member.

Claim 3

A combination as set forth in claim 1 in which said exterior shoulder is a radial flange; in which said latch means is constructed to engage said radial flange to releasably hold the valve member at its open position; and in which the latch means has a cam surface constructed to ride over said exterior shoulder on the housing means to cause the latch means to engage said exterior shoulder on the housing means to cause the latch means to engage said exterior shoulder in locking relationship in response to axial movement of the valve member to its closed position.

Claim 4

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 movable axially within the axial passage in the housing between first and second 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, 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, and second means disposed on the valve member and extending externally from the valve member and cooperative with the first means in the first position of the valve member for retaining the valve member in the first position, and third means extending externally of the housing and cooperative with the second means On the valve member for limiting the movement of the valve member to the second position and for retaining the valve member in the second position.

Claim 5

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 movable axially within the axial passage in the housing between first and second 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, 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, and second means disposed on the valve member and extending externally from the valve member and cooperative with the first means in the first position of the valve member for retaining the valve member in the first position, and third means extending externally of the housing and cooperative with the second means On the valve member for limiting the movement of the valve member to the second position and for retaining the valve member in the second position.

Claim 6

Apparatus as set forth in claim 2 wherein the first means includes a first flange and the second means includes at least one latch arm having a construction for engaging the first flange and the third means includes a second flange on the housing at a position removed from the first flange in the transverse direction for engaging the latch arm in the second position of the valve member.

Claim 7

Apparatus as set forth in claim 4 wherein the passage in the housing is cylindrical and the valve member is cylindrical and is rotatable in the passage to release the valve member from retention of the latch arm on the valve member by the first flange on the housing in the first position and to provide for the movement of the valve member to the second position.
