Abstract
Abstract A waffle baker where rectangular base and cover case components support circular waffle grids within opposing smooth heated faces defining thereby a heated spill over area annularly adjacent the grids for collecting and solidifying spillage for easy cleaning; where bolts are extended completely through the case component and threaded into taps on the underside of the grid to leave exposed actuating tool heads for easy removal of the bolts and grids without otherwise disassembling the baker; and where a sheath type electric resistance heating element bent to shape is held removably within a fixture and in good heat transfer relationship against the grid underside and a thermostat is spring biased against the grid underside to allow grid removal and replacement without recalibration of the baker.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
226 words
A waffle baker comprising base and cover case components each having an annular closure element with an outer peripheral rim and an inner peripheral lip and a smooth face therebetween, a fixture secured to each closure element on the under side thereof within the respective case component, each said fixture having opposed shoulders and an interconnecting ledge disposed peripherally within the alignment of the lip, a heating element removably supported on each fixture ledge and having a curved intermediate configuration and opposing outer legs where the heating element legs are wedged against the opposing fixture shoulders, a grid adapted to fit into each closure element and against the peripheral lip thereof and against the heating element, means for securing each grid to its case component including a bolt extended through the case component and threaded in a tap on the grid underside, means hinging the case components together where the peripheral rims oppose and abut each other and the smooth faces oppose each other in spaced relation, each face being heated by conduction from the heating element, whereby spillage onto the base case component face is at least partially baked to permit removal thereof with a fork or like cooking tool, a sensing buLb, and means to mount the temperature sensing bulb under a compressive force against and in heat sensing relation to one grid underside.

Claim 3
Dependent Claim
43 words
A waffle baker according to claim 1, wherein the heating element curved intermediate configuration includes a plurality of closed loops whereby the opposing legs are the outermost part of the closed loop and are biased apart by the resiliency of the heating element.
Claim 4
Dependent Claim
45 words
A waffle baker according to claim 1, wherein the configuration of the cooperating peripheral rims is generally square and where the configuration of the grids is generally circular and whereby each closure element face extends completely around its grid between the rim and the grid.
Claim 5
Dependent Claim
38 words
A waffle baker according to claim 1, wherein a sleeve is press fitted or otherwise secured onto the grid underside in spaced concentric relation to the tap therein for guiding the bolt into registry with the grid tap.
Claim 6
Dependent Claim
146 words
A waffle baker comprising base and cover case components each having an inner peripheral lip, a fixture secured to each case component, each said fixture having opposed shoulders and an interconnecting ledge disposed peripherally within the alignment of the lip, a heating element removably supported on each fixture ledge and having a curved intermediate configuration and opposing outer legs where the heating element legs are wedged against the opposing fixture shoulders, a grid adapted to fit against the peripheral lip and against the heating element, legs are wedged against the opposing fixture shoulders, a grid adapted to fit against the peripheral lip and against the heating element, means for securing each grid to its case component including a bolt extended through the case component and threaded in a tap on the grid underside, and means hinging the case components together where the grids abut each other.
Claim 7
Dependent Claim
146 words
A waffle baker comprising base and cover case components each having an inner peripheral lip, a fixture secured to each case component, each said fixture having opposed shoulders and an interconnecting ledge disposed peripherally within the alignment of the lip, a heating element removably supported on each fixture ledge and having a curved intermediate configuration and opposing outer legs where the heating element legs are wedged against the opposing fixture shoulders, a grid adapted to fit against the peripheral lip and against the heating element, legs are wedged against the opposing fixture shoulders, a grid adapted to fit against the peripheral lip and against the heating element, means for securing each grid to its case component including a bolt extended through the case component and threaded in a tap on the grid underside, and means hinging the case components together where the grids abut each other.
Claim 8
Dependent Claim
38 words
A waffle baker according to claim 5, wherein a sleeve is press fitted or otherwise secured onto the grid underside in spaced concentric relation to the tap therein for guiding the bolt into registry with the grid tap.
Claim 9
Dependent Claim
39 words
A waffle baker according to claim 5, further including a temperature sensing bulb, and means carried on the fixture to mount the temperature sensing bulb under a compressive force against and in heat sensing relation to the grid underside.
Claim 10
Dependent Claim
141 words
A waffle baker comprising base and cover case components each having an annular closure element with an outer peripheral rim and an inner peripheral lip and a smooth face therebetween, a pair of heating elements and means on each closure element for holding a respective heating element within the case component and the alignment of the lip, a grid adapted to fit against the peripheral lip and against the heating element, means for securing each grid to its case component, and means hinging the case components together where the peripheral rims oppose and abut each other and the smooth faces oppose each other in spaced relation, each face being heated by conduction from the heating element, whereby spillage onto the base case component face is at least partially baked to permit removal thereof with a fork or the like cooking tool.
