BACKGROUND OF THE INVENTION 
This invention relates to the field of Gutter Anti-Clogging Devices and 
particularly relates to screens affixed to gutters to prevent debris from 
impeding the desired drainage of water. 
Various gutter anti-clogging devices are known in the art and some are 
described in issued patents. 
U.S. Pat. No. 2,734,467 to Steele describes a GUTTER SCREEN having a 
generally planar mesh bounded by U-shaped reinforcing means at inner and 
outer ends. The inner end of screen rests on the end of a sloped roof and 
the outer end is resiliently secured to the outer articulated wall of the 
gutter by flat split brackets which apparently bias the inner edge of the 
mesh against the roof. 
U.S. Pat. No. 2,841,100 to Moller describes a MOVABLE SCREEN FOR EAVES 
TROUGHS having a generally planar mesh bounded at its outer end by a 
reinforcing rod and having an inner end resting on the end of a sloped 
roof. The reinforcing rod is pivotally secured to an outer edge of a 
gutter by U-shaped brackets and the mesh may be pivoted outward by 
downward force on arms projecting outwardly of the gutter. Alternately, a 
combined spring and bracket fixedly secures the reinforcing rod to the 
outer edge of the gutter. 
U.S. Pat. No. 3,351,206 to Wennerstrom describes a STRUCTURE FOR SECURING 
GUTTER SCREENING TO BUILDING GUTTERS. A flat mesh is disposed horizontally 
or tilted inwardly toward the roof. The inner edge of the mesh rests on 
the roof and the outer edge is secured to an outer edge of a gutter by a 
structure extending along the outer longitudinal edge of the mesh which 
grasps the mesh between an upper and middle arm and an inner directed 
horizontal flange of the gutter between the middle and lower arm. 
U.S. Pat. No. 3,834,091 to Dugan describes a HINGED GUTTER COVER including 
a plurality of planar mesh sections each peripherally surrounded by a 
rigid rod frame. The outer rod is pivotally secured to the outer edge of 
the gutter and the inner rod rests on the end of a sloped roof. A dumping 
handle extends outwardly of the gutter to allow a mesh section to be 
pivoted outward. 
U.S. Pat. No. 4,553,356 to Pepper describes a RAINWATER GUTTER SEALING 
ARRANGEMENT. The arrangement includes an arcuate perforated joining strip, 
bowed upwardly, exerting force against a sealing strip adjacent a facia by 
being placed in compression by the outer edge of a gutter. 
U.S. Pat. No. 4,533,357 to Pepper describes an ADJUSTABLE RAINWATER GUTTER 
MOUNTING ARRANGEMENT. The mounting arrangement of this patent allows the 
base of the gutter shown in the Pepper '356 patent to be adjusted to slope 
slightly outward. 
U.S. Pat. No. 4,616,450 to Shouse describes an EAVES TROUGH/RAIN GUTTER 
SHIELD having a solid upper surface and a depending outward flange 
containing rain guidance apertures and rain receiving apertures. 
SUMMARY OF THE INVENTION 
The invention is of a gutter anti-clogging device for preventing a gutter, 
affixed to a facia of a building from being clogged with debris. 
The gutter is mounted beneath an overhang of a roof and has a basically 
U-shaped cross section. An inner gutter leg extends upwardly, and 
longitudinally along, the facia. A gutter base extends generally 
horizontally outward from, and longitudinally along, the inboard gutter 
leg. An outer gutter leg extends upwardly from, and longitudinally along, 
the gutter. 
The gutter anti-clogging device includes mesh and retaining clips. 
The mesh, defines mesh orifices surrounded by longitudinal wire and 
transverse wire, and extends longitudinally along the gutter. The mesh has 
an L-shaped cross section with an integral inner mesh leg and an integral 
sloped mesh leg. The inner mesh leg is disposed adjacent the inner gutter 
leg and extends above an uppermost end of the outer gutter leg. The 
integral sloped mesh leg extending downwardly and outwardly from an upper 
end of the inner mesh leg to an upper end of the outer gutter leg. 
The retaining clips have a generally inverted U-shaped section with an 
inner clip leg, a clip base and an outer clip leg. The inner clip leg is 
inserted downward through a mesh orifice. The clip base extends outward of 
the inner clip leg, and the outer clip leg extends downward from the clip 
base and the upper end of the outer gutter leg to fictionally secure the 
clip and mesh to the gutter.

DETAILED DESCRIPTION OF THE DRAWING 
FIG. 1 is a cross-section of the gutter anti-clogging device 10 of the 
present invention in its intended environment secured to a gutter 12 
affixed to the facia 14 of a building beneath an overhanging roof 16. 
Gutter 12 has a basically U-shaped cross section. An inner gutter leg 18 
extends upwardly, and longitudinally along, the facia 14. A gutter base 20 
extends generally horizontally outward from, and longitudinally along, the 
inboard gutter leg 18. An outer gutter leg 22 extends upwardly from, and 
longitudinally along, the gutter base 20. At the upper end 24 of the outer 
gutter leg 22, there is an inward directed gutter flange 26. Spikes 28 at 
preselected longitudinal intervals are typically driven through the outer 
and inner gutter legs 18, 22 and into facia 14 to secure gutter 12 to 
facia 14. Often as illustrated, the portion of the spikes 28 between inner 
gutter leg 18 and outer gutter leg 22 is surrounded by cylindrical tube 30 
which can be considered as a part of spike 28 herein. 
The gutter anti-clogging device 10 includes mesh 32 and retaining clips 34. 
Mesh 32, defines mesh orifices 36 surrounded by longitudinal wire 38 and 
transverse wire 40, and extends longitudinal along the gutter. The mesh 
has an acute angled L-shaped cross section with an integral inner mesh leg 
42 and an integral sloped mesh leg 44. The inner mesh leg 42 is disposed 
adjacent the inner gutter leg 18 and extends above an uppermost end 46 of 
the inner gutter leg. The integral sloped mesh leg 44 extends downwardly 
and outwardly from the upper end 48 of the inner mesh leg 42 to the upper 
end 24 of the outer gutter leg 22. Normally, for residential use where 
economy dominates, carbon steel mesh in flat sheets is bent at upper end 
48 to create mesh 32 of the proper dimensions. Although mesh of a variety 
of dimensions may be employed, wire of approximately 0.03125 inch (0.08 
cm.) diameter defining orifices of approximately 0.25 inch (0.64 cm.) by 
0.60 inch (1.5 cm.) is preferred. For installations which are awkward to 
replace, galvanized steel, stainless steel, bronze, or other corrosion 
resistant materials, such as plastic coated steel, may be employed. In 
most installations where spikes 28 fasten gutter 12 to facia 14, it is 
desirable to remove portions of the longitudinal wires 38 to create slots 
50 in inner mesh leg 42 to allow the inner mesh leg 42 to extend below 
spikes 28 as shown in FIG. 4. In most cases it is advantageous to have the 
lower end 52 of inner mesh leg 42 rest on gutter base 20 as shown in FIG. 
1. However, where spikes 28 are employed the inner leg may be supported by 
spikes 28 at the upper end 54 of a slot 50 as shown in FIG. 4. 
The retaining clips 34 have a generally U-shaped cross section with a inner 
clip leg 56, a clip base 58, and an outer clip leg 60. The inner clip leg 
56 is inserted downward through a mesh orifice 36. The clip base 58 
extends outward of the inner clip leg 56, and the outer clip leg 60 
extends downward from the clip base 58 and the upper end 24 of the outer 
gutter leg 22 to fictionally secure the clip 34 and mesh 32 to the gutter 
12. The clip 34 should have resilient legs 56, 60 and is preferably 
fabricated from plastic or spring steel. Corrosion resistant materials are 
desirable when corrosion resistant mesh is employed. Where gutter inner 
flange 26 is present, it is desirable to form clip inner leg 56 so that it 
extends outward and under inner flange 26, as shown in FIG. 4. 
It will be observed that the upper portion 44 of the screen is inclined 
downwardly toward its outer edge to facilitate any debris cascading off 
the roof to readily roll off the screen. Furthermore, if necessary, if the 
screen becomes clogged and requires removal, the fasteners 24 may be 
easily unsnapped and the screen withdrawn from under the roofing paper 16 
and then rotated about its outer edge to withdraw portion 42, or the 
screen may be withdrawn sidewise. The depth of portion 42 will prevent any 
debris which has hung up on the edge of paper 16 from falling into the 
gutter as portion 42 is withdrawn from under the roofing. Also the angular 
relations of portions 42, 44 forms a corner at 48, thus rigidifying the 
screen strip lengthwise thereof.
