Method of providing a clutch for a spool
View Patent ↗The method of mechanically controlling the rotation of a spool comprising a clutch providing a first position in which a first motive force is applied to the spool through the clutch, providing a second position in which a second motive force is applied to the spool through the clutch, providing third position intermediate to the first position and the second position in which both the first motive force and the second motive forces are applied to the spool through the clutch, such that there during the movement between the first position, the third position, and the second position there is no time at which at least one of the first motive force or the second motive force is not applied to the spool.
1. The method of mechanically controlling a rotation in either direction of a driven spool for offshore vessels loading stations comprising the steps of:
providing said spool on an offshore vessel or dock wherein said spool is adapted to be used with a hose of about a three inch to about six-inch diameter, said hose capable of floating and passing liquids and dry powders, and said spool is adapted to raise and lower said hose without slipping;
providing a motor to drive said spool for said raising and said lowering of said hose;
providing a clutch in communication with said motor and said spool and said clutch is constantly engaged with said spool and said motor;
providing a first position in which a first motive force is applied to said spool through said clutch,
providing a second position in which a second motive force is applied to said spool through said clutch,
providing a third position intermediate to said first position and said second position in which both said first motive force and said second motive forces are applied to said spool through said clutch,
such that there during a movement between said first position, said third position, and said second position there is no time at which at least one of said first motive force or said second motive force is not applied to said spool, said clutch remains in constant engagement with said spool and said clutch is never in neutral; and
controlling said rotation in either direction of said driven spool for offshore vessels loading stations.
2. The method of claim 1 further comprising that said first motive force is a rotational force.
3. The method of claim 1 further comprising that said second motive force is a braking force.
4. The method of claim 1 further comprising that said first motive force is a rotational force and said second motive force is a braking force and said spool will not rotate in said second position and said third position.
5. The method of claim 1 further that said clutch is comprised of providing a multiplicity of pins which engage a multiplicity of slots.
6. The method of claim 1 further that said clutch is comprised of providing an external gear with an internal gear.
7. The method of claim 1 further that said clutch is comprised of providing an external spline with an internal spline.
