A drain filtering device is disclosed. The improvement over the prior art is comprised of includes reducing the filter size from an elongated device that spans the length of the gutter drain system to a modular unit which is necessary only at the drain sight outlet. The invention also includes filtering device has an inclined upper face which is positioned on the upstream side of the drain in the gutter and a downspout channel of the drain and an attachment which locates the invention filtering device in the gutter channel such that the flow of filtered water passes through the invention device and into the downspout outlet. The debris that collects in the gutter channel is carried along the with the water until it makes contact with the inclined upper face and is forced up the incline until the overflow debris flows over the side of the gutter channel thereby cleaning the same and preventing the downspout outlet from becoming clogged.

1. Field of the Invention
The invention disclosed herein relates to a device for filtering open drains and thereby preventing them from being clogged. More particularly this invention relates to a device for filtering drains, the drains including and culvert side faces 20. Though the structure is shown here to be of wire mesh construction the present invention could be manufactured of a variety of materials in which end itself to be with the objective being to provide a structure that is durable and non-corrosive in nature and possesses a permeability to water but not to leaves and similar debris.
With reference now to FIG. 2, the sectioned view of the invention as depicted in FIG. 1 is shown. In this view a bottom face 22 is shown with a down spout attachment 24 which consists of a hollow extension fastened to the bottom face 22 encapsulating a hole in the bottom face 22. If the bottom face is made of a water permeable material the presence of the hole in the bottom face 22 is not necessary.
The upper face 12 is also shown in greater detail in FIG. 2. The inclined portion 14 is shown with a front curve. This curve projects out more along the midline or section line of this view. The purpose of the curve is to further assist the leaves and other debris from sticking to the inclined portion 14.
The down spout attachment 24 is shown extending out of the bottom face 22 and is capable of being received by the downspout in a typical gutter system. This locates the invention in the gutter and directs the filtered water into the downspout.
The invention can also be made in a five face unit, as best seen in FIG. 3. In this case the upper face 26 has only an inclined portion that connects the bottom face 22 and the rear face 18. The rest of the attributes of the invention are similar to the six faced device as shown in FIG. 1 and disclosed herein.
FIG. 4 shows another alternative design of the invention. In this the upper face 28 is comprised of a series of slats 30 which then provide a plurality of openings on a upward slant of the incline portion 32. In this case the preferred embodiment of the invention would be constructed of a rigid material such as galvanized sheet metal or molded plastic. Additional slots 34 are positioned along the vertical faces 36 and the flat portion 38 of the upper face 28 to accommodate the passage of water into the cavity of the device and eventually out into the downspout. In this case the device is similar to those already mentioned.
A sectioned view of the preferred embodiment as shown in FIG. 4 and sectioned along the line B--B, is shown in FIG. 5. In this view the down spout attachment 40 is shown as a continuous member of the bottom face 42. The slats 30 which comprise the inclined portion of the upper face 28 is shown in more detail. It can be easily seen that water can easily pass between the slats 30 into the cavity of the device and out the down spout attachment 40.
FIG. 6 shows a typical application of the invention. In this case the invention filtering device 44 is positioned in the gutter 46 of a building 48 aligning the down spout attachment 50 with the down spout opening 52. The invention filtering device 44 is positioned such that the upper face 54 is facing the open side 56 of the gutter.
The action of the invention filtering device 44 is shown in FIG. 7 as a section cut along the line C--C in FIG. 6. In this the leaves 58 and other debris are washed from the roof 60 into the gutter 46, and the water 62 in the gutter 46 carries the debris 58 on its way to the downspout 64. When the debris 58 contact the upper face 54 of the invention 44 filtering device, the water is able to pass therethrough into the downspout 64 but the debris 58 being physically to too large to fit through, the material is pushed up the inclined portion of the upper face 54. This continues until the height of the debris 58 is greater than the height of the gutter 46 and overflow debris 66 falls out of the gutter 46.
The invention has uses which include any open trench or canal with side walls and a drain or outlet. FIG. 8 shows a typical example of an open ditch 68 in which the water must pass through an opening, such as a culvert 70 under a roadway 72. In this, the invention 74 is similarly placed into the water passageway 68 only in this case, the spout attachment 76 situated in the rear face 78 of the invention 74. This is A filtering device 74 made in accordance with principles described above is placed in the ditch 68 adjacent to the entrance to the culvert 70, that is adjacent to the outlet from the ditch. In this case, a spout attachment 76 projects from the rear face 78 of the filtering device, due to the commonly horizontal arrangement of the culvert 70 alignment of the inlet or entrance to the culvert and the outlet from the ditch or channel of the drain system. Accordingly, the attachment is fitted into the entrance to the culvert. The debris 80 is picked up out of the flowing water 82 by virtue of being forced up the inclined portion 84, in a manner as previously described.
