Abstract
A hand held spreading device is disclosed for broadcast spreading material via a rotating impeller. The device has an actuating assemly including an actuating member and a dual spring arrangement interconnected with the actuating member. One of the springs causes material to be discharged onto the impeller in response to movement of the actuating member and prevents damage of the device resulting from excessive movement of the actuating member. The second spring biases the actuating member to move to an idle position in which no material is discharged onto the impeller and causes the actuating member to return to this idle position after movement thereof.
Claims20
A hand-held material spreading device comprising:
- a housing having a storage chamber and a manually engagable pistol grip-type handle;
- said storage chamber being positioned over an impeller and including a port for discharging material from said storage chamber onto said impeller, said impeller being disposed and structured to rotate and to broadcast said material deposited thereon;
- a valve member mounted for reciprocal motion across said port to regulate the flow of material in response to operation of an actuating assembly;
- said actuating assembly including an actuating member mounted on the surface of said pistol grip-type handle and a dual spring arrangement interconnected with said actuating member;
- and
- said dual spring arrangement including a first spring for moving said valve member in response to movement of said actuating member to open said port to allow said flow of material and to close said port to stop such flow of material, said first spring also preventing damage of said device resulting from excessive movement of said actuating member and a second spring for biasing said actuating member to an initial, idle position and for causing said actuating member to return to said idle position after said actuating member has been moved.
A hand-held spreading device comprising:
- a housing including a storage chamber;
- an impeller;
- means for discharging material from said storage chamber onto said impeller for broadcasting said material;
- an actuating assembly interconnected with said discharging means for operating said discharging means;
- said actuating assembly including an actuating member and a dual spring arrangement interconnected with said actuating member;
- said dual spring arrangement including a first spring extending from said actuating member in a first direction and a second spring extending from said actuating member in a direction generally opposite said first direction;
- said first spring being structured and dimensioned to cause said discharging means to discharge material in response to movement of said actuating member and to prevent damage of said device resulting from excessive movement of said actuating member;
- and
- said second spring being structured and dimensioned to bias said actuating member to move to an idle position at which said first spring will not cause said discharging means to discharge material and for causing said actuating member to return to said idle position after said actuating member has been moved.
