Abstract
This invention discloses an ornamental fountain wherein a fountain nozzle is made to discharge a pressurized stream of liquid, and a shutter prevents or allows the stream to exit.
Claims9
Control shutter assembly for a water fountain comprising:
- a fountain nozzle having means to discharge a pressurized stream of water;
- a shutter located adjacent said nozzle which prevents or allows said stream to exit;
- said shutter integrally connected to a rotatable shaft;
- an armature having a tip composed of magnetic material at one end and at the other end.
- affixed to the said rotatable shaft, whereby the opening and closing of said shutter is controlled by said armature;
- a fixed stop located adjacent a blocking position of said armature,
- at least two, first and second electromagnets having magnetic cores mounted adjacent said armatue tip;
- said armature tip positioned in close proximity to said electromagnets such that in one position said armature stays positioned against said stop whenever said first electromagnet remains activated, and said shutter continues to block said exit port and no water is discharged;
- and whereby by de-activating said first electromagnet and activating sais second electromagnet, said armature is made to rotate said shaft and said shutter will rotate so that it is no longer blocking said exit orifice, and said stream will traverse through said exit aperture, and wherby in order to stop the flow said first electromagnet is deenergized and said second electromagnet is energized to move the armature in the direction of said bumper to return said armature and said shutter to said first position.

A control shutter according to claim 3 wherein three of said second electromagnets are provided.
A control shutter assembly for a water fountain comprising:
- a fountain nozzle having means to discharge a pressurized stream of water;
- a shutter located adjacent said nozzle which prevents or allows said stream to exit;
- said shutter integrally connected to a rotatable shaft;
- means for rotating said shaft and opening said shutter comprising an electrical solenoid mounted on a fixed support having a plunger mechanically connected a lever by a pin said lever in turn mechanically connected to said shutter;
- said lever adopted to overcome the force of a tension spring mounted on a fixed support adjacent to said lever;
- whereby upon de-activating said solenoid, the force of said tension spring pulls said lever to withdraw said plunger, rotates said shaft, and closes said shutter to block fluid flow;
- and whereby when said solenoid is in an actuated condition in which said plunger is withdrawn, stretched said spring and rotated said lever, rotated said pin and rotated said shutter to uncover said aperature.

- a shutter located adjacent said nozzle which prevents or allows said stream to exit;
- said shutter integrally connected to a rotatable shaft;
- means for rotating said shaft and opening said shutter comprising an electrical solenoid mounted on a fixed support having a plunger mechanically connected a lever by a pin said lever in turn mechanically connected to said shutter;
- said lever adopted to overcome the force of a resilient means mounted on a fixed support adjacent to said lever;
- whereby upon de-activating said solenoid, the force of said resilient means pulls said lever, and closes said shutter to block fluid flow;
- and whereby when said solenoid is in an actuated condition said resilient means rotates said lever, and moves said shutter to uncover said aperature.
