ABSTRACT:
An auxiliary portable lock which comprises a housing, a lock body receivable within said housing, and adapted for axial rotation therein, said housing being internally communicative with a tubular casing axially normal to the longitudinal axis of said housing and being open at its opposite ends. There is an elongated locking bar having a serrated surface provided for extension through said tubular casing and having integrally formed at one of its ends, a door-engaging portion. A cooperative serrated member is provided within said housing for movement toward and away from the confronting portion of said locking bar for maintaining same in selected disposition; said cooperative serrated member is operatively engaged to said lock body which latter, through rotative movement effects translation of said cooperative serrated member. A door engaging element is formed at one end of said tubular casing. Key control components are provided to secure said lock body to said housing. An anti-distortion device is detachably mounted upon said lock body for indicating unauthorized linear or rotative movement thereof.
Another version of the lock of this invention embodies cooperating clamping components interengaged by an elongated screw operatively manipulated by said lock body whereby said clamping components may be drawn toward each other, on opposite sides of aligned doors to retain same in closed condition.
