Abstract
Abstract A tension link control device generally comprised of an inner cylinder and an outer cylinder with a uniquely configured fracture link connected therebetween. The link has a specially configured thread and cross sectional area which permits a considerable amount of axial play in the threads. Slots are provided at the interface end of the outer cylinder. Tapped holes are provided in the inner cylinder to align the slots. The inner cylinder has a flange which mates with the outer cylinder assembly. The axial compression loads are absorbed in the outer housing by allowing the cylinders to contact before axial play in the threads will allow compression to be transmitted to the fracture link.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
337 words
A tension link control device comprising: a. first and second force transmitting means; b. said first force transmitting means having first and second sections, said first section including at least one force transmitting element, and said second section including a hollow cylindrical member and a threaded member; c. said second force transmitting member having first and second sections, said first section including at least one force transmitting element, and said second section including a hollow cylindrical means; d. the inside diameter of the hollow cylindrical member being greater than the outside diameter of said hollow cylindrical means; e. said hollow cylindrical means including inside threads and being inserted into one end of said hollow cylindrical member; f. a frangible tension link comprising a cylindrical member having a first threaded end and a second threaded end with a reduced portion therebetween; g. said first threaded end being in engagement with said threaded member of said first force transmitting means and said second threaded end being in engagement with said inside threads of said second force transmitting means; h. torsional means for transmitting a torque between said first and second force transmitting means independent of said first and second threaded ends; whereby i. said threads of said first and second threaded ends are selected to have a pitch that permits a considerable amount of axial play with respect to the threads of said threaded member and said inside threads respectively for transmitting tension loads between said first and second force transmitting means; j. a plurality of slots arranged radially in the cylindrical member of said first force transmitting means; k. a plurality of tapped holes corresponding to said slots and arranged radially in said hollow cylindrical means of said second force transmitting means; l. attaching means for maintaining each of said slots and tapped holes in a fixed relationship; whereby m. torsional forces applied to said first force transmitting means are transferred to said second force transmitting means without transfer of any of said force to said tension link.
Claim 2
Dependent Claim
337 words
A tension link control device comprising: a. first and second force transmitting means; b. said first force transmitting means having first and second sections, said first section including at least one force transmitting element, and said second section including a hollow cylindrical member and a threaded member; c. said second force transmitting member having first and second sections, said first section including at least one force transmitting element, and said second section including a hollow cylindrical means; d. the inside diameter of the hollow cylindrical member being greater than the outside diameter of said hollow cylindrical means; e. said hollow cylindrical means including inside threads and being inserted into one end of said hollow cylindrical member; f. a frangible tension link comprising a cylindrical member having a first threaded end and a second threaded end with a reduced portion therebetween; g. said first threaded end being in engagement with said threaded member of said first force transmitting means and said second threaded end being in engagement with said inside threads of said second force transmitting means; h. torsional means for transmitting a torque between said first and second force transmitting means independent of said first and second threaded ends; whereby i. said threads of said first and second threaded ends are selected to have a pitch that permits a considerable amount of axial play with respect to the threads of said threaded member and said inside threads respectively for transmitting tension loads between said first and second force transmitting means; j. a plurality of slots arranged radially in the cylindrical member of said first force transmitting means; k. a plurality of tapped holes corresponding to said slots and arranged radially in said hollow cylindrical means of said second force transmitting means; l. attaching means for maintaining each of said slots and tapped holes in a fixed relationship; whereby m. torsional forces applied to said first force transmitting means are transferred to said second force transmitting means without transfer of any of said force to said tension link.
Claim 3
Dependent Claim
65 words
The device of claim 1, including: a. a shoulder formed in said second force transmitting means; b. the end of said cylindrical member of said first force transmitting means abutting against said shoulder; whereby c. compression and bending forces applied to said first force transmitting means are transferred to said second force transmitting means without transfer of any of said force to said tension link.
