Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
159 words
A termination anchorage for a circular termination member where said anchorage includes a bracket having a U-shaped slot contained therein adapted to engage with an annular groove in said termination member; the improvement comprising in having a coil spring lock adapted to surround a termination member where the inner diameters of the coils of the coil spring lock are less than the outer diameter of the termination member when the coil spring lock is in an unstressed state, in having a spring tip on said coil spring lock extending parallel to the longitudinal axis of the coils, and in having a hole in said bracket adapted to be engaged by said spring tip whereby when the annular groove of a termination member is engaged by said slot, said coil spring lock will lock and engage with said termination member and said tip will engage with said hole to prevent movement of the annular groove out of said U-shaped slot.
Claim 2
Dependent Claim
159 words
A termination anchorage for a circular termination member where said anchorage includes a bracket having a U-shaped slot contained therein adapted to engage with an annular groove in said termination member; the improvement comprising in having a coil spring lock adapted to surround a termination member where the inner diameters of the coils of the coil spring lock are less than the outer diameter of the termination member when the coil spring lock is in an unstressed state, in having a spring tip on said coil spring lock extending parallel to the longitudinal axis of the coils, and in having a hole in said bracket adapted to be engaged by said spring tip whereby when the annular groove of a termination member is engaged by said slot, said coil spring lock will lock and engage with said termination member and said tip will engage with said hole to prevent movement of the annular groove out of said U-shaped slot.
Claim 3
Dependent Claim
84 words
A termination anchorage according to claim 1, the improvement further comprising in that said coil spring lock has a radially extending handle on the end of said coil spring opposite said spring tip whereby an uncoiling force may be applied to said coil spring lock to increase the inner diameters of the coils to allow the coil spring lock to be moved longitudinally with respect to the termination member in order to move the spring tip with respect to the hole in the bracket.
Claim 4
Dependent Claim
52 words
A termination anchorage according to claim 2, the improvement further comprising in having a resilient collar surrounding the coils of said coil spring lock whereby binding of adjacent coils of the spring lock is prevented when an uncoiling force is applied to the handle to increase the inner diameters of the coils.
