Adjustable oscillating fan-jet sprinkler
First Claim
1. An oscillating fan-jet sprinkler for the irrigation of a substantially rectangular area from a supply of pressurized water, the sprinkler having a housing with an inlet for pressurized water, a sprinkler stand supporting said housing while resting on a substantially horizontal supporting plane, an elongated nozzle cylinder extending from the sprinkler housing in a generally horizontal direction, the nozzle cylinder being journalled in said housing for oscillation about its longitudinal axis, a row of nozzle bores on the upper side of an exposed portion of the nozzle cylinder defining a fantail pattern of spray jets within a spray plane, and oscillation drive means including a turbine wheel inside the sprinkler housing driven by the incoming pressurized water and drive translation means converting the rotary motion of the turbine wheel into a slow oscillatory motion of the nozzle cylinder, the improvement therein comprising:
- means for angularly shifting the oscillation range of the nozzle cylinder by angularly adjusting the structural relationship between the nozzle cylinder and the sprinkler stand independently of the oscillation drive and of the drive translation means, the oscillation range shifting means including;
a housing support as part of the sprinkler stand, the sprinkler housing being releasably attached to the housing support by securing means; and
a rotational connection between the sprinkler housing and the housing support defining an adjustment axis which is parallel to the axis of the nozzle cylinder, the oscillation range of the nozzle cylinder being shiftable by adjusting the angular position of the sprinkler housing in its rotational connection to the housing support.

Abstract
A fan-jet sprinkler of the type which has an oscillating horizontal nozzle cylinder driven by a turbine wheel and a translation drive, the sprinkler having a rotational connection between its stand and housing, or between the nozzle cylinder and an oscillating drive sleeve, so that the oscillation range can be shifted by adjusting the angular relationship between the oscillation range and the sprinkler stand independently of the drive transmission.
