Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
148 words
A cover for an outdoor grill comprising: a cover body provided with a draft opening in the top of the body; a generally planar weather shield overlapping the opening, said shield having an aperture aligned with the opening; means supporting the shield on the body in vertically spaced relationship from the upper surface of the latter, the spacing between the shield and the body presenting an air inlet; a barrier surrounding the opening and spanning the distance between the shield and the body, there being at least one gap in the barrier for passage of air from the inlet to the opening; a rotatable damper in the aperture closing the latter, said damper including structure carried by the damper and disposed to close said gap in the barrier when the damper is rotated to a predetermined position, whereby to selectively restrict the passage of air into the grill.
Claim 2
Dependent Claim
148 words

Claim 3
Dependent Claim
43 words
The invention set forth in claim 1, wherein said barrier and said structure are semicircular, the structure being of lesser diameter than the barrier and being disposed for rotation along a circular path of travel within the circle partially defined by said barrier.
Claim 4
Dependent Claim
44 words
The invention of claim 2, wherein said opening is circular, and wherein the circle defined by said barrier is of greater diameter than the opening, said structure being disposed to slidably engage the upper surface of the body between the barrier and the opening.
Claim 5
Dependent Claim
42 words
The invention of claim 3, wherein the aperture is circular, said damper including an upwardly extending portion projecting through the damper, said portion presenting an annular, outwardly facing shoulder disposed to slidably engage the inner edge of said shield defining said aperture.
Claim 6
Dependent Claim
31 words
The invention of claim 4 wherein said damper includes an outwardly extending flange integral with said portion, said flange having an upper surface extending beneath said shield entirely around said aperture.
Claim 7
Dependent Claim
17 words
The invention of claim 5, wherein said structure is secured to the lowermost surface of the flange.
Claim 8
Dependent Claim
47 words
The invention of claim 1, wherein said barrier includes a pair of elongated, semicircular walls integral with the lowermost surface of the shield and depending therefrom, the walls being spaced circumferentially around the opening to present a pair of said gaps between the ends of the walls.
Claim 9
Dependent Claim
59 words
The invention of Claim 7, wherein said structure includes a pair of circumferentially spaced, semicircular wall structures integral with the damper and depending therefrom, said wall structures being shaped to complementally fit within the circle defined by the barrier walls and each wall structure having a length at least as great as the length of each of said gaps.
Claim 10
Dependent Claim
64 words
The invention of claim 8, wherein said damper is provided with knob means projecting upwardly through said aperture to facilitate manual rotation of the damper, and wherein said shield is provided with indicia around the aperture to indicate the relative rotated position of the damper with respect to the shield, whereby to reveal the position of said wall structures with respect to said gaps.
Claim 11
Dependent Claim
30 words
The invention of claim 9, wherein is provided a window in the cover body for visual observation of the interior of the grill to indicate optimum regulation of said damper.
