  "abstract": "A leveling device enables adjustable positioning of cooking pans on stove burners where the stove is offset from the horizontal. The device includes first and second annular members that are fitted together for relative rotation on the stove surface. The first annular member includes a recess and first surface that receives a projection and second surface of the second annular member. The surfaces are planar and juxtaposed so that both members may be rotated freely. The surfaces are angularly inclined with respect to a support surface of the second member. By rotating the two annular members relative to one another and the stove framework, the upper member can be selectively adjusted to bring the support surface into a horizontal orientation. Handles are provided on the two members to facilitate relative rotation while a pan rests on the support surface.",
  "claims": [
    "1. An adjustable cooking surface device for a cook stove, comprising: a base member having planar lower surface means thereon for engagement upon a cook stove framework; said base member having a first planar annular surface formed thereon facing oppositely to said lower surface means; a cooking support member having planar upper surface means thereon for engagement by cooking implements; said cooking support having a second planar annular surface formed thereon facing oppositely to said upper surface means; said first and second planar annular surfaces, being complementary and in sliding engagement with one another for relative coaxial angular movement between said base member and said cooking support member; said first and second planar annular surfaces being in planes inclined relative to the planar lower surface means and planar upper surface means, respectively, by angles of inclination identical to one another, whereby relative coaxial angular movement between said base member and cooking support member will position the planar upper surface means parallel to the planar lower surface means or at a selected angle thereto limited by the angles of inclination of said first and second planar annular surfaces.",
    "2. An adjustable cooking surface device as set out in claim 1 wherein said cooking support member further comprises: a handle fixed thereto and extending outward beyond its periphery.",
    "3. An adjustable cooking surface device as set out in claim 1 wherein said base member further comprises: a handle fixed thereto and extending outward beyond its periphery.",
    "4. An adjustable cooking surface device as set out in claim 1 wherein said cooking support member and said base member each further comprise: a handle fixed thereto and extending outward beyond its periphery, whereby coaxial angular movement can be imparted to either the base member or cooking support member relative to one another and relative to a cook stove framework engaged by said base member."
