Abstract
A retainer device is used with a screed assembly including a main screed and a pair of front-mounted screed extensions connected with the main screed. Each extension is pivotally attached to the main screed and has a front surface facing generally away from the main screed. The retainer device includes a retainer plate disposed adjacent to the front surface of the screed extension. A horizontally-extending rod has a first end connected with the retainer plate and a second end connected with the main screed. The rod is configured to displace the retainer plate between a first, most distal position with respect to the main screed and a second, most proximal position with respect to the main screed. At the most proximal position, the retainer member acts upon the screed extension such that the screed extension is retained generally in contact with the main screed. Further, the plate prevents rotation of the screed extension in a direction generally away from the main screed.
