Drain filtering device

A [gutter] filter for a drain system in which water and debris including leaves move along a passageway toward an outlet, comprising:

• A. a rigid structure having at least two substantially vertical faces and at least three additional faces including a bottom face, a rear face and an upper face, all of the faces being pervious to water but not to undesired debris found in the water, the combination forming a closed three dimensional polygon, at least one face having a section of material removed therefrom, creating a hole therein and having a hollow tube attached thereto, thereby forming a hollow extension out of the face, and [a hollow portion thereby being continuous] being in communication with the interior of the closed polygon;
• B. the rear face positioned adjacent to said bottom face and said vertical faces, thereby adjoining said faces;
• and
• C. the upper face adjoined at some acute angle to said bottom face and also adjoined with said vertical faces and said rear face, whereby said hollow extension is capable of being received by the [downspout] outlet of a [gutter] drain system with the closed three dimensional polygon being received by the [gutter] passageway , the upper face and adjoining faces allowing the water from the gutter to pass into the [downspout] outlet without the leaves and other undesired debris, which are forced up the incline created by the upper face with respect to said bottom face, by the flowing water, thus carrying the debris [over] to the sides of the [gutter] passageway and cleaning same, thus preventing the debris from clogging the [downspout] outlet .

[21. The filter as described in claim 20, wherein said mesh material is

• comprised of galvanized steel wire.]22. The filter as described in claim 20, wherein said mesh material is comprised of a plastic material. . A filter for a drainage system having a channel providing a bottom surface along which water and debris move toward an outlet, comprising:
• A. a water-pervious three-dimensional structure having top, bottom and rear faces and a pair of side faces, said top face being an inlet face, and at least one of said bottom, rear and side faces being an outlet face, the outlet face being porous, the top face being porous to water but not to undesired debris so that water can pass therethrough and enter the structure but undesired debris cannot, said top face joining the bottom face at an acute angle defining a lower front corner of the structure and creating a ramp leading up from the corner along the top face,
• B. said structure having a channel positioning member extending therefrom capable of positioning the structure in the channel of a drain system with the outlet face in fluid communication with the outlet from the channel, with the bottom face lying on the bottom surface of the channel, with the front corner meeting the bottom surface of the channel, and with the top face forming an obtuse angle with said bottom surface, whereby water flowing in the channel flows through the top face into the structure but debris in the water strikes the top face and is forced upwardly along the ramp and off the top face to clear the same.

A drain filtering device for use in a drainage system wherein water and debris are channeled toward an outlet comprising:

• a three-dimensional, multi-faced structure having a top, a bottom, opposite sides, a front and a rear,
• said structure also having a plurality of faces, one of which is a top inlet face porous to water but not to undesired debris that could clog an outlet from the drainage system, and another of which is an outlet face porous to water,
• said structure having an internal passageway that allows water entering the top face to pass therethrough to the outlet face,
• said top face being directly connected at some acute angle to the bottom of the structure and forming a ramp leading directly upwardly and rearwardly from the bottom of the structure;
• and
• a locating member projecting from the structure adapted to position the structure in the drain system so that the top face can intercept water and debris flowing in the drain system, so that water can enter the structure through the inlet face and exit the structure through the outlet face into the outlet, and so that undesired debris in the water will be forced against the top face and thence upwardly therealong by following debris washed thereagainst by the flowing water.

A filter for a drain system in which water and debris including leaves move along a passageway toward an outlet, comprising:

• A. a rigid cage-like structure having at least two side faces and at least three additional faces including a bottom face, a rear face and a top face, all of the faces being pervious to water but not to undesired debris found in the water, the combination forming said structure, at least one face having a hole therein and having a hollow tube attached to the face over the hole and thereby being in communication with the interior of the structure,
• B. the rear face positioned adjacent to said bottom face and said side faces, thereby adjoining said faces, and
• C. the top face adjoined at some acute angle to said bottom face and also
• adjoined with said side faces and said rear face.

A drain filtering device for use in a drain system in which water and debris flow along a passageway toward an outlet, comprising:

• a porous multi-sided structure having a hollow interior defined by bottom, top, side and rear faces,
• the bottom face having front and rear edges,
• the top face being water-pervious and having a lower front edge and opposite side edges, being directly joined at its lower front edge to the front edge of the bottom face, and extending angularly upwardly from the bottom face at an acute angle and forming a ramp that starts at the juncture of the lower front edge and the front edge and inclines upwardly therefrom,
• the side faces being respectively joined to the side edges of the top face and extending downwardly therefrom,
• the rear face being joined to the rear edge of the bottom face and extending upwardly therefrom,
• the top face being an inlet into the structure and one of the bottom, side, and rear faces being an outlet from the interior of the structure;
• and
• a positioning member extending outwardly from the structure and adapted to position the structure in the passageway of a drain system so that the structure is in the path of water and debris flowing in the passageway with the bottom face on the bottom of the passageway and with the top face in a position to intercept the flowing water and debris, whereby the water and debris contact the ramp of the top face and the debris is pushed upwardly along the ramp by the water and the water passes through the top face, enters the interior of the structure and exits the interior of the structure through the outlet face and thence into the outlet of the drain
• system.

A drain filtering device comprising:

• a filter body having opposite sides, a bottom, a front, and a rear,
• the body having a size and a shape that allows it to be positioned in a drainage channel that contains a stream of flowing water and debris so that the front of the body is positioned upstream of the rear of the body relative to the direction of flow of the water and the debris so that the flowing water and debris initially engage the front of the body,
• said filter body having a water inlet at the front and a water outlet spaced from the inlet,
• said filter body also allowing water entering the body through the inlet to pass to and out of the body through the outlet, and
• the front of the body being a water-pervious ramp extending directly upwardly at some acute angle from the bottom thereby to intercept the flowing water and debris and cause the debris to be diverted outwardly of the flowing stream of water which is allowed to enter the body through the inlet whereby the debris is separated from the water and is prevented from clogging the channel.
