ABSTRACT:
An automatic temperature responsive assembly for ventilating through a roof a confined space to the atmosphere whereby heat buildup in the confined space may be released from the confined space or fresh air permitted to enter therein. The assembly comprises housing means adapted to be coupled to the roof of the confined space and having an opening extending therethrough with cover means operatively associated with the housing means and mounting means operatively associated with the housing means for pivotally securing the cover means thereto, so as to be movable between a generally open position and a generally closed position for enclosing the opening. A temperature responsive drive assembly is mounted to detect temperature changes in the confined space and adapted to actuate in response to temperature changes within a predetermined range, and camming means is pivotally secured relative to the housing means and including a camming surface thereon for engaging the drive assembly. Transmission means operatively extends between the cover means and the camming means for communicating movement of the drive assembly through the camming means, such that the cover means is moved to varying positions in response to temperature changes in the confined space, and guide means for providing controlled movement of the transmission means in the directions for obtaining the open position and the closed position of the cover means is provided, so as to obtain an automatic closing of the cover means in relationship to the movement in the drive assembly.
