Abstract
Abstract Apparatus for accelerating the heating of a cooking vessel positioned over a heat source including a sleeve adapted to surround the side wall of the cooking vessel. The sleeve includes an inner face which is spaced from the vessel side wall and is interrupted by a plurality of inwardly directed projections. The projections are spaced about the circumference of the sleeve inner face and are adapted to terminate adjacent the vessel side wall and to define in conjunction therewith a plurality of passages through which heat from the heat source may pass in intimate contact with the vessel side wall.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
199 words
Apparatus for accelerating the heating of a cooking vessel positioned over a heat source comprising: a sleeve adapted to surround the side wall of said vessel and including spaced annular marginal edges, said sleeve having inner and outer cylindrical band parts and an insulative member disposed between said band parts, said inner band part having an inner face adapted to oppose said vessel side wall and an outer face opposing said insulative member, said band parts and insulative member being substantially coextensive, said inner band part including means constituting spaced parallel projections and defining circumferentially narrow uninterrupted heat flow passages extending along said inner face of the inner band part from one said marginal edge to the other said marginal edge of the sleeve, said projections being aligned with the axis of said inner band part and being adapted to project outwardly from said inner face of the inner band part to adjacent said vessel side wall so as to define in conjunction with said vessel side wall said heat flow passages through which the heat from said heat source may pass in heat transferring contact with said vessel side wall when said sleeve surrounds said vessel side wall.
Claim 2
Dependent Claim
199 words
Apparatus for accelerating the heating of a cooking vessel positioned over a heat source comprising: a sleeve adapted to surround the side wall of said vessel and including spaced annular marginal edges, said sleeve having inner and outer cylindrical band parts and an insulative member disposed between said band parts, said inner band part having an inner face adapted to oppose said vessel side wall and an outer face opposing said insulative member, said band parts and insulative member being substantially coextensive, said inner band part including means constituting spaced parallel projections and defining circumferentially narrow uninterrupted heat flow passages extending along said inner face of the inner band part from one said marginal edge to the other said marginal edge of the sleeve, said projections being aligned with the axis of said inner band part and being adapted to project outwardly from said inner face of the inner band part to adjacent said vessel side wall so as to define in conjunction with said vessel side wall said heat flow passages through which the heat from said heat source may pass in heat transferring contact with said vessel side wall when said sleeve surrounds said vessel side wall.
Claim 3
Dependent Claim
22 words
The apparatus of claim 1, wherein said projections extend from adjacent one said marginal edge to adjacent the other said marginal edge.
Claim 4
Dependent Claim
12 words
The apparatus of claim 2, wherein said projections are equally spaced apart.
Claim 5
Dependent Claim
15 words
The apparatus of claim 1 wherein said sleeve is split so as to be expansible.
Claim 6
Dependent Claim
28 words
The apparatus of claim 4, including adjustable means interconnecting the split-defining ends of said sleeve for varying the spacing between said ends to accommodate vessels of different sizes.
Claim 7
Dependent Claim
17 words
The apparatus of claim 1, wherein said insulative member is spaced from one of said band parts.
Claim 8
Dependent Claim
58 words
The apparatus of claim 1, wherein said insulating member is positioned adjacent said outer band part, said projections extending outwardly from said band part inner face, a plurality of circumferentially spaced protrusions extending outwardly from said band part outer face and contacting said insulating member to cause said inner band part to be spaced from said insulating member.
Claim 9
Dependent Claim
50 words
The apparatus of claim 1, including support means carried by said sleeve at said inner face, said support means having parts projecting toward the center of said sleeve adapted to engage said vessel when surrounded by said sleeve for supporting one of said sleeve and vessel relative to the other.
Claim 10
Dependent Claim
53 words
The apparatus of claim 8, wherein said support means comprise a plurality of hanger members each having a generally horizontal base which projects inwardly toward the cEnter of said sleeve and beyond said projections, said hanger members spaced circumferentially about said inner face with the bases thereof lying in substantially the same plane.
Claim 11
Dependent Claim
60 words
The apparatus of claim 9, wherein said sleeve includes upper and lower marginal edges and said hanger members are L-shaped and include generally vertical leg parts, each vertical leg part having said generally horizontal base at one end thereof and a downturned hook portion at its opposite end, said hook portion received over the upper marginal edge of said sleeve.
Claim 12
Dependent Claim
151 words
Apparatus for accelerating the heating of a cooking vessel positioned over a heat source and having a side wall comprising: a sleeve surrounding said vessel side wall, said sleeve having inner and outer cylindrical band parts and an insulative member disposed between said band parts, said band parts and insulative member being substantially coextensive, said inner band part having an outer face contacting said insulative member and an inner face interrupted by at least ten elongated projections paralleling the axis of said inner band part, said projections being substantially equally spaced about the circumference of said inner face and extending to adjacent said vessel side wall, said inner face defining in conjunction with said vessel side wall and projections a plurality of uninterrupted passages between said vessel side wall and said inner band through which heat from said heat source may pass in heat transferring contact with said vessel side wall.
Claim 13
Dependent Claim
151 words
Apparatus for accelerating the heating of a cooking vessel positioned over a heat source and having a side wall comprising: a sleeve surrounding said vessel side wall, said sleeve having inner and outer cylindrical band parts and an insulative member disposed between said band parts, said band parts and insulative member being substantially coextensive, said inner band part having an outer face contacting said insulative member and an inner face interrupted by at least ten elongated projections paralleling the axis of said inner band part, said projections being substantially equally spaced about the circumference of said inner face and extending to adjacent said vessel side wall, said inner face defining in conjunction with said vessel side wall and projections a plurality of uninterrupted passages between said vessel side wall and said inner band through which heat from said heat source may pass in heat transferring contact with said vessel side wall.
