Abstract
A simple, quick, quiet load-release device which comprises a standard thred nut cut into three sections along its length. The three sections are held together by use of a heat meltable tape which is wrapped around the nut. A resistance wire is laid between layers of the tape and upon application of a current through the resistance wire, the tape melts permitting the nut sections to separate and release any load supported by the release device.
Claims11
A simple, quiet, load-release device for use with a threaded bolt in securing a load comprising:
- a threaded nut,
- said nut machined circumferentially along a portion of its outer surface to have the shape of a bobbin and severed into three equal sections along its length;
- a meltable tape for wrapping in layers around said nut sections when assembled into a whole and within the machined portion of said nut to prevent radial disassembly;
- and
- an electrical resistance means for assembly between the layers of meltable tape,
- whereby a suitable electrical current passed through said resistance means generates heat and melts said tape permitting the sections of said nut to separate and release the load.

- said nut cut circumferentially along a portion of its outer surface to form the shape of a bobbin and severed into three equal sections along its length;
- a meltable tape wrapped in layers around said nut sections assembled into its whole with the tape within the bobbin to prevent radial disassembly;
- electrical resistance means secured between a layer of said tape;
- and
- a threaded bolt for threading into said nut,
- whereby a load to be released is held by said bolt passing through a load holding means and threaded into said nut.
