Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
152 words
A device for combining two lines of objects, more particularly containers, arranged spaced apart from each other or in groups to form a single line comprising: a. blocking arms pivotable about axes perpendicular to the plane of said two lines, said axes located between said two lines and said blocking arms normally extending into the lines perpendicular to the direction of travel of the objects to prevent passage of said objects, b. locking discs attached to said blocking arms so as to be pivotable therewith, said discs having a cam surface on at least a portion of their peripheries, and c. movable locking means engaging said cam surfaces on said locking discs to prevent rotation of one locking disc and its associated blocking arm while allowing rotation of said other locking disc and blocking arm out of the path of travel of its corresponding line to allow passage of said object thereby.
Claim 2
Independent Claim
152 words
A device for combining two lines of objects, more particularly containers, arranged spaced apart from each other or in groups to form a single line comprising: a. blocking arms pivotable about axes perpendicular to the plane of said two lines, said axes located between said two lines and said blocking arms normally extending into the lines perpendicular to the direction of travel of the objects to prevent passage of said objects, b. locking discs attached to said blocking arms so as to be pivotable therewith, said discs having a cam surface on at least a portion of their peripheries, and c. movable locking means engaging said cam surfaces on said locking discs to prevent rotation of one locking disc and its associated blocking arm while allowing rotation of said other locking disc and blocking arm out of the path of travel of its corresponding line to allow passage of said object thereby.
Claim 3
Dependent Claim
27 words
The device according to claim 1 wherein the axes of the blocking arms are located in a plane parallel to the longitudinal axes of the two lines.
Claim 4
Dependent Claim
29 words
The device according to claim 1 wherein the movable locking means is caused to lock one of said locking discs against rotation by rotation of the other locking disc.
Claim 5
Dependent Claim
39 words
A device according to claim 1, characterized in that the locking means is in the form of a locking roller arranged on a swivel arm and projects into a corresponding recess of the locking disc to lock the same.
Claim 6
Dependent Claim
34 words
A device according to claim 4, characterized in that the cam surface on each of the locking discs is a generally circular arc and the recess is located at one end of said arc.
Claim 7
Dependent Claim
21 words
The device according to claim 4 wherein the locking roller is located intermediate the axes of rotation of the locking discs.
