Abstract
A storm window latch mechanism which permits easy removal of a storm window sash when the latch mechanism is placed in one position and yet positively secures said storm window sash within the mounting framework when the latch mechanism is in a second position with freely slidable up and down movement being permitted. The latch mechanism includes a spring slider assembly having a low friction slide component mounted on the face thereof, with retention prongs provided on each of the respective ends of the spring member for engagement in appropriate apertures of the window sash, and a positive acting lever and bias spring structure connected to the middle portion of the resilient flexible spring member for actuation thereof. The lever portion is provided with two adjustment recesses which cooperate with a properly configured channel member mountable upon the edge channel of the window sash. A cooperating coil spring positively biases the latching lever into locked position whenever it is not being manipulated by an operator of the window sash. All of the components may be easily manufactured and assembled, and are relatively inexpensive.
