Abstract
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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
139 words
An auxiliary door lock comprising a lock body having means defining a casing, means defining a housing receiving said lock body casing for rotational movement of the latter within the former, means latchably interengaging said casing and said housing in selected relative position, an elongated element engaged to said casing for axially linear movement responsive to rotation of said casing, means defining a sleeve rigid with said housing and having its major axis normal to the longitudinal axis of said lock body, a toothed member freely extending through said sleeve for projection at its ends therebeyond, and cooperating means comprising a component carried on said elongated element interengageable with said toothed member for maintaining same in selected relative position in said sleeve, and means provided on one end of said toothed member engageable with the door to be locked.
Claim 2
Dependent Claim
139 words
An auxiliary door lock comprising a lock body having means defining a casing, means defining a housing receiving said lock body casing for rotational movement of the latter within the former, means latchably interengaging said casing and said housing in selected relative position, an elongated element engaged to said casing for axially linear movement responsive to rotation of said casing, means defining a sleeve rigid with said housing and having its major axis normal to the longitudinal axis of said lock body, a toothed member freely extending through said sleeve for projection at its ends therebeyond, and cooperating means comprising a component carried on said elongated element interengageable with said toothed member for maintaining same in selected relative position in said sleeve, and means provided on one end of said toothed member engageable with the door to be locked.
Claim 3
Dependent Claim
47 words
An auxiliary door lock as defined in claim 1 and further characterized by a flange formed on one end of said sleeve, and a tongue provided on the end of said toothed member at the end thereof corresponding to the end of said sleeve carrying said flange.
Claim 4
Dependent Claim
56 words
An auxiliary door lock as defined in claim 1 and further characterized by a stop flange formed on one end of said sleeve, and a hook-forming device engageable with a door to be locked provided on the end of said toothed member at the end thereof corresponding to the end of said sleeve carrying said flange.
Claim 5
Dependent Claim
23 words
An auxiliary door lock as defined in claim 3 and further characterized by said flange and said tongue extending away from each other.
Claim 6
Dependent Claim
29 words
