Abstract:
A rotary sprinkler including a sprinkler head, a drive motor and a drive train drivingly coupled to the motor and to the sprinkler head so that the motor can impart rotational movement to the sprinkler head. The drive train includes a shifter drivable between first and second positions for reversing the direction of the rotational output of the drive train. A buckling column spring provides the energy to move the shifter between the first and second positions. A one piece seal is used to provide a plurality of separate annular seals as well as to assist in mounting one or more components of the rotary sprinkler.
To become a fossil, the body of an animal must be buried, and in most cases, animal remains are consumed or destroyed by other animals shortly after death, Richard Holtz, a vertebrate paleontologist and principal lecturer at the University of Maryland, told Insider.
