ABSTRACT:
A novel telescoping heat responsive releasing device is described wherein a mounting member on which heat responsive and locking means are mounted slidingly enages a pawl member which is movable between a first position in which the pawl member is capable of being restrained by the aforementioned latching means, and an activated position wherein associated apparatus connected to said releasing device may assume the desired heat responsive posture. In the preferred embodiment, a biasing means is provided for biasing said mounting member and said pawl member from said activated position towards said first or normal position.
