Abstract
Abstract A connecting link for transmitting linear motion along its axis to feed bore wedges of insulating material and having an overload release mechanism is disclosed. The connecting link consists of an outer link, and an inner link slidable relative to the outer link in the direction of transmission of the force. The inner link is provided with a recess and the outer link is provided with a spring loaded plunger arrangement which engages the recess and which yields allowing the relative sliding of the inner and outer links when the force being transmitted by the connecting link exceeds a predetermined value.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
149 words
In an arrangement for winding and inserting coils and strips of insulating material wherein insulating material is fed for a definite length, cut, formed into a U-shape, and inserted in a magnetic member; a feed mechanism overload release comprising: a first elongated member; a second member adapted to be movably interconnected with said first member; means limiting the relative motion said first and second members to a linear motion in the direction of elongation of said first member; and release means adapted to prevent said linear motion when the component of the forces being transmitted by said link in the direction of said linear motion is less than a predetermined value, and to yield allowing said linear motion when said component force exceeds said predetermined value whereby a blockage in the flow of insulating material actuates the feed mechanism overload release to prevent the feeding of additional insulating material.
Claim 2
Dependent Claim
149 words
In an arrangement for winding and inserting coils and strips of insulating material wherein insulating material is fed for a definite length, cut, formed into a U-shape, and inserted in a magnetic member; a feed mechanism overload release comprising: a first elongated member; a second member adapted to be movably interconnected with said first member; means limiting the relative motion said first and second members to a linear motion in the direction of elongation of said first member; and release means adapted to prevent said linear motion when the component of the forces being transmitted by said link in the direction of said linear motion is less than a predetermined value, and to yield allowing said linear motion when said component force exceeds said predetermined value whereby a blockage in the flow of insulating material actuates the feed mechanism overload release to prevent the feeding of additional insulating material.
Claim 3
Dependent Claim
40 words
The combination of claim 1 wherein said release means comprises: a recess in one of said first and second members; and a spring loaded plunger mechanism passing through the other of said members and adapted to yieldably engage said recess.
Claim 4
Dependent Claim
98 words
The combination of claim 2 wherein said spring loaded plunger mechanism comprises: a holder, a plunger, a spring, and a set screw; one end of said holder fixedly retained in said other member, said holder having an axis which is substantially perpendicular to said direction of elongation of said first member, the other end of said holder being provided with internal threads; said plunger adapted to be forced into said recess by said spring and said spring tension being adjustably maintained by said set screw when said set screw is threaded into said other end of said holder.
Claim 5
Dependent Claim
28 words
The combination of claim 3 wherein said plunger comprises a ball and a plug, said ball engaging said recess and said plug engaging said spring and said ball.
Claim 6
Dependent Claim
40 words
The combination of claim 1 wherein said release means comprises a spring loaded plunger and a set screw, said set screw adapted to vary the spring tension and wherein said predetErmined value may be selected by adjusting said set screw.
