Adjustable sprinkler
First Claim
1. An adjustable sprinkler connectable to a pressurized water source, said adjustable sprinkler comprising:
- an outer housing including inlet means for receiving the pressurized water;
an inner housing positioned within said outer housing and including a body and a head rotatably connected to the body, said head including outlet means for emitting the pressurized water received by said inlet means;
setting means for setting the boundaries of a spray pattern, said setting means positioned inside said inner housing;
cover means for covering a top of said inner housing, said cover means defining an opening adapted to receive an adjuster for adjusting said setting means to change at least one of the boundaries of said spray pattern;
rotating means for generating rotational movement to rotate the head about an axis in one direction and in an opposite direction between the boundaries of said spray pattern;
coupling means for coupling the rotating means to said head; and
resisting means for providing resistance to said coupling means, said resisting means being in frictional engagement with said coupling means, wherein said resisting means enables the coupling means to rotate with said rotating means during normal operation and rotate independently from said rotating means if the head is manually rotated.

Abstract
An adjustable sprinkler including an inner housing slideably engaged with an outer housing. The inner housing includes a head rotatably mounted to a body. The outer housing includes an inlet which receives pressurized water and transfers the pressurized water to a nozzle attached to the head. The inner housing includes a reverser for selectively driving an impeller in two different directions. The impeller is connected to a reducer which reduces the rotational rate transferred from the impeller to the head and also enables the head to be manually rotated without causing damage to the internal components of the adjustable sprinkler. The head includes a click set and a cap. The cap defines at least one opening to enable a user to insert a tool through the cap to adjust and set the boundaries of the spray pattern using the click set.

8. An adjustable sprinkler connectable to a pressurized water source, said adjustable sprinkler comprising:
-
an outer housing defining a water inlet;
an inner housing mounted in said outer housing, said inner housing including a body and a head rotatably connected to the body, said body being slideably connected to said outer housing;
a water outlet connected to said head;
a driver mounted in said head, said driver rotatable in one direction and in an opposite direction at a designated rate of rotation;
a reverser positioned adjacent to said driver, said reverser operable to change the direction of said driver;
a spray pattern controller coupled to the reverser, said spray pattern controller being adjustable to set a spray pattern having a first boundary and a second boundary, said spray pattern controller adapted to receive an adjuster controllable for adjusting at least one of said first and second boundaries of said spray pattern;
at least one resistor connected to an inside surface of said body; and
a reducer connected between said driver and a rotary output member, said reducer operable to rotate said rotary output member in the same direction as said driver and at a rate of rotation less than said rate of rotation of said driver, wherein said reducer is in frictional engagement with said resistor of said body to enable said reducer to rotate the head in unison with the rotation of said rotary output member and independently rotate the head separate from the rotation of the rotary output member if said head is manually rotated. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
