Abstract
A lawn sprinkler and bearing therefore is provided. The lawn sprinkler has first and second rotatable sprinkler elements supported on a support stand. The bearing allows the sprinkler elements to rotate in opposite directions to evenly distribute fluid over an area to be irrigated.
Claims14
A bearing for rotatably supporting first and second sprinkler elements on a supporting stand, each of the sprinkler elements having a corresponding neck, comprising:
- a hollow, generally cylindrical bushing extending along a longitudinal axis and defining a fluid receiving chamber therein, the bushing including a first open end operatively connected to the supporting stand such that the fluid receiving chamber communicates with the interior thereof, and a second, opposite closed end, the bushing further including first and second sets of longitudinally spaced apertures therein, the first set of apertures received within the neck of the first sprinkler element and the second set of apertures received within the neck of the second sprinkler element;
- a tubular bushing sleeve rotatably received within the neck of the first sprinkler element and on the bushing, the bushing sleeve having an aperture therethrough lying in a common plane with the first set of apertures in the bushing such that the interior of the first sprinkler element successively communicates with fluid receiving chamber in the bushing through the aperture in the bushing sleeve and through one of the first set of apertures in the bushing as the bushing sleeve rotates about the bushing in response to the flow of fluid from the fluid receiving chamber in the bushing to the interior of the first sprinkler element;
- a generally tubular support sleeve rotatable supported on the bushing, the support sleeve extending along the longitudinal axis between the first and second sets of apertures in the bushing.
A bearing for a lawn sprinkler having first and second rotatable sprinkler elements supported on a support stand, each of the sprinkler elements having a corresponding neck, comprising:
- a hollow, generally cylindrical bushing extending along a longitudinal axis and defining a fluid receiving chamber therein, the fluid receiving chamber communicating with the interior of support stand, the bushing including a first set of circumferentially spaced apertures therein which are received within the neck of the first sprinkler element;
- and a second set of circumferentially spaced apertures therein, the second set of apertures longitudinally spaced from the first set of apertures in the bushing and received within the interior of the second sprinkler element;
- a bushing sleeve interconnected to and extending through the neck of the first sprinkler element, the bushing sleeve rotatably received on the bushing and having an aperture extending therethrough, the aperture lying in a common plane with the first set of apertures in the bushing such that the interior of the first sprinkler element successively communicates with fluid receiving chamber in the bushing through the aperture in the bushing sleeve and through one of the first set of apertures in the bushing in response to rotation of the bushing sleeve about the bushing;
- a generally tubular support sleeve rotatably supported on the bushing, the support sleeve extending along the longitudinal axis between the first and second sets of apertures in the bushing.

A lawn sprinkler, comprising:
- a hollow, support stand extending along a longitudinal axis, the support stand connectable to a fluid source for transmitting fluid therethrough;
- a generally cylindrical bushing extending along a longitudinal axis and defining a fluid receiving chamber therein, the fluid receiving chamber communicating with the interior of the support stand, the bushing including a first set of circumferentially spaced apertures therein;
- a fluid distributing member having a neck and a fluid dispersing opening therein to accommodate the flow of fluid therethrough;
- a bushing sleeve extending through and interconnected to the neck of the fluid distributing member, the bushing sleeve rotatably received on the bushing and having an aperture therethrough, the aperture lying in a common plane with the first set of apertures in the bushing such that the interior of the fluid distributing member successively communicates with fluid receiving chamber in the bushing through the aperture in the bushing sleeve and through one of the first set of apertures in the bushing in response to rotation of the bushing sleeve about the bushing;
- and
- a second fluid distributing member having a plurality of fluid dispersing opening therein;
- and
- a generally tubular support sleeve interconnected to and partially received in the second fluid distributing member, the support sleeve rotatably supported on the bushing.
