Abstract
Abstract A cooking device comprising upper and lower hemispheres wherein the peripheral rim of the lower hemisphere is tilted at an angle to the axis of a pedestal support to which it is rigidly secured. The upper hemisphere is rotatably mounted on the lower hemisphere so as to rotate about a common axis of each, and is dimensioned so as to rotate without interference over at least a portion of the outer surface of the lower hemisphere. Stop means are provided to preclude rotation of the upper hemisphere in the other direction over the lower hemisphere so that the upper hemisphere forms a hood for the lower hemisphere. A grill is horizontally supported in the lower hemisphere by means of ramp means on the inner surface of the lower hemisphere and a rigid rod on the grill that cooperates with the said tilted portion of the peripheral rim.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
112 words
A cooking device comprising a lower hemisphere and a hemispherical hood adapted to rotate on a common, substantially diametric axis of both hood and said lower hemisphere; said lower hemisphere being rigidly supported from beneath and in an attitude such that the peripheral rim thereof is inclined at an angle to the horizontal, the outside diameter of said lower hemisphere and the inside diameter of said hemispherical hood being such that there is no interference between the hemispherical hood and the lower hemisphere as the former rotates about said common axis over at least a portion of the latter; and wherein at least one grill is horizontally supported in said lower hemisphere.
Claim 2
Dependent Claim
112 words
A cooking device comprising a lower hemisphere and a hemispherical hood adapted to rotate on a common, substantially diametric axis of both hood and said lower hemisphere; said lower hemisphere being rigidly supported from beneath and in an attitude such that the peripheral rim thereof is inclined at an angle to the horizontal, the outside diameter of said lower hemisphere and the inside diameter of said hemispherical hood being such that there is no interference between the hemispherical hood and the lower hemisphere as the former rotates about said common axis over at least a portion of the latter; and wherein at least one grill is horizontally supported in said lower hemisphere.
Claim 3
Dependent Claim
149 words
The cooking device of claim 1 wherein the support means for said at least one grill comprises two ramps placed on the inner surface of said lower hemisphere, an a rigid rod extending diametrically outwardly from said lower grill; said grill being adapted at two places on its periphery to contact and be supported by said ramps, and said peripheral rim of said lower hemisphere being adapted to support said rigid rod, the spacing of said two places and said rigid rod about the periphery of said grill being at substantially 90* intervals; said ramps being placed in said lower hemisphere so that the spacing of said ramps and of a portion of the peripheral rim of said lower hemisphere is substantially identical to the spacings of said two places and said rigid rod about the periphery of said grill, at any point along the length of said ramps.
Claim 4
Dependent Claim
68 words
The cooking device of claim 2 further comprising means to adjust the elevation of said at least one grill; wherein said last mentioned means includes said two ramps and a plurality of notches formed in said portion of said peripheral rim; said portion of said peripheral rim being chosen such that the spacing relationship between said portion and said ramps is substantially constant throughout said portion, as aforesaid.
