초록 ▼

A pair of counter-wound spring-like members are placed in a gutter above an opening communicating with a downspout. A cord joined to the spring-like members extends through said downspout and out of an opening in the downspout. The cord is pulled and released to contract and expand the spring-like m

대표청구항 ▼

The invention claimed is: 1. In combination, a gutter having an opening communicating with an upper end of a downspout and a device positioned in said gutter and above said opening for preventing leaves and other debris from passing through said opening, said device comprising: a first tapered helical coil; a second tapered helical coil surrounding said first helical coil; narrow ends of said tapered coils being joined; said coils being positioned in said gutter so that wide ends of said coils are positioned above said gutter opening and said joined narrow ends extending away from said gutter opening; said first tapered helical coil being wound in a reverse direction from said second tapered helical coil; a cord having one end coupled to said joined ends and extending generally along a central axis of said coils and downward through said gutter opening and said downspout; an opposite end of said cord passing through an opening in said downspout below said gutter for contracting said helical coils when said cord is pulled downwardly; and said helical coils expanding when said cord is released, whereby contraction and expansion of said helical coils crushes and grinds debris extending into said helical coils to enable the debris to be carried by liquid passing through said device and entering into said downspout. 2. The combination of claim 1 further comprising a member coupled to the end of said cord extending through said opening in said downspout to prevent the end of cord from reentering said downspout. 3. The combination of claim 1 wherein said tapered helical coils have diameters at said wide ends which are at least equal to a diameter of the opening in said gutter communicating with said downspout. 4. The combination of claim 1 wherein said gutter has an end wall adjacent to said gutter opening; and the wide ends of said helical coils engaging said end wall whereby when said cord is pulled in a downward direction said helical coils contract due to movement of the joined narrow ends of the helical coils toward said gutter end wall. 5. A method for installing a combination strainer and grinder device enabling water and small size debris to pass through said device and being selectively contractable and expandable to grind and crush debris, comprising: placing said device in a gutter and above an opening in said gutter communicating with an upper end of a downspout; the gutter comprising a horizontal bottom surface, a front wall, a rear wall, and two vertical end walls; coupling a cord to one end of said device; extending said cord through a central region of said device and through a passageway in said device located above said gutter opening and downwardly through said downspout; forming an opening in said downspout at a location a given distance below said gutter opening; pulling said cord through said opening; and placing an opposite end of said device against a vertical end wall of said gutter adjacent to said gutter opening to limit movement of said device when said cord is drawn downwardly thereby causing said device to contract to crush and grind debris entering passageways in said device. 6. The method of claim 5 further comprising: releasing said cord enabling said device to expand and thereby enable liquid and debris smaller than a given size to pass through said device and into said downspout.
