Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
48 words
An anti-rattling device for a linkage including: a pivoted arm forming part of the linkage, a member on which the arm is pivoted, and a compressible roller also mounted on the member adjacent to the arm and engaging the latter on an external surface surrounding the pivot point.
Claim 2
Dependent Claim
48 words
An anti-rattling device for a linkage including: a pivoted arm forming part of the linkage, a member on which the arm is pivoted, and a compressible roller also mounted on the member adjacent to the arm and engaging the latter on an external surface surrounding the pivot point.
Claim 3
Dependent Claim
22 words
A device as in claim 1 in which the external surface is a cam surface surrounding the pivot point and eccentric thereto.
Claim 4
Dependent Claim
29 words
A device as in claim 1 including spaced parallel pins on the member, on one of which the arm is pivoted and the other of which supports the roller.
Claim 5
Dependent Claim
69 words
An anti-rattling device including: a fixed member, a movable member in parallel relation to the fixed member and movable toward and away from the fixed member, parallel links connecting the members to maintain the parallel relation, said links being pivoted to both members, and a compressible roller mounted adjacent to one end of at least one of said links and engageable with an external surface of the associated link.
Claim 6
Dependent Claim
69 words
An anti-rattling device including: a fixed member, a movable member in parallel relation to the fixed member and movable toward and away from the fixed member, parallel links connecting the members to maintain the parallel relation, said links being pivoted to both members, and a compressible roller mounted adjacent to one end of at least one of said links and engageable with an external surface of the associated link.
Claim 7
Dependent Claim
23 words
A device as in claim 4 in which the external surface is a cam surface surrounding the pivot point of the adjacent link.
Claim 8
Dependent Claim
36 words
A device as in claim 4 including spaced parallel pins on the movable member, on one of which the roller is mounted and on the other of which the adjacent end of the link is pivoted.
Claim 9
Dependent Claim
20 words
A device as in claim 6 in which the cam surface is eccentric to the pivot axis of the link.
