Title: Telescoping heat responsive releasing means

Abstract: A novel telescoping heat responsive releasing device is described wherein a mounting member on which a bimetallic means is mounted slidingly engages a pawl member which is movable between a first position in which the pawl member is capable of being restained by the aforementioned bimetallic means, and an actuating position wherein associated apparatus connected to said releasing device may assume the desired heat responsive posture. Various alternate embodiments are illustrated wherein a plurality of bimetallic elements are utilized to engage the pawl member, wherein a bimetallic element is additionally actuated mechanically or electrically, and wherein various pawl and mounting member configurations are illustrated.
