  • Sash lock with improved tumbler
    Patent number: 5536052
    Abstract: A tumbler is pivotably mounted in a sash lock housing. In an extended position, an end of the tumbler limits movement of a window sash. A post in the housing extends through an eccentric bore in the tumbler. The bore defines a shelf or protrusion that urges the tumbler into engagement with the housing, thereby preventing over-rotation of the tumbler in the extended position. A spring urges the tumbler toward the extended position and cooperates with the protrusion to urge the tumbler into engagement with the housing.
