  • Patent number: 4174860
    Abstract: A latch for ovens and the like includes a latch subassembly movable between latching and unlatching positions, a high temperature locking pawl engageable with the latch subassembly at a preselected elevated temperature to block its movement to unlatching position, and a thermal element which moves the locking pawl into blocking position. First adjustment means is provided to engage the locking pawl during its movement from a nonblocking position to the blocking position so as to locate its abutment surface in a predetermined position in the path of movement of the latch subassembly. Second adjustment means is also provided and is engageable with the locking pawl during its movement from blocking position to non-blocking position so as to locate the abutment surface on the pawl in a predetermined position.

  • Patent number: 4133337
    Abstract: A latch for ovens and the like includes a latch subassembly movable between latching and unlatching positions, a high temperature locking pawl which is engageable with the latch subassembly at a preselected elevated temperature to block its movement to unlatching position, and a thermal element which rotates the pawl into the blocking position. Resiliently deflectable means is provided on the locking pawl to rotate the pawl into blocking position in the event that the latch subassembly is moved from the latched position towards the unlatched position as the preset elevated temperature for latching is approached, thereby compensating for lag in response of the thermal element and preventing opening of the oven door at elevated temperatures.
