Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
170 words
A corn popper having a base, an open top pot supported on said base for popping the corn, stirring means within said pot, drive means for said stirring means including a motor in said base, a flexible lid for the pot to cause popped corn to exit the pot at the perimeter thereof, an annular shroud surrounding said cooking pot and at a lower level, said shroud having a downwardly extending wall with perforations and a surrounding chamber of generally U-shaped cross section for collection of popped corn which leaves the open top pot, air passages in said base connecting external air to the perforations in said wall for flow of external air through the collected popped corn, a circulating air fan in said base driven by said motor for inducing said air flow, and an open top storage bin removably attached to said shroud and partially overlying the pot perimeter for guiding popped corn exiting the pot to said chamber while permitting moisture-laden air to leave the corn popper.
Claim 2
Dependent Claim
170 words
A corn popper having a base, an open top pot supported on said base for popping the corn, stirring means within said pot, drive means for said stirring means including a motor in said base, a flexible lid for the pot to cause popped corn to exit the pot at the perimeter thereof, an annular shroud surrounding said cooking pot and at a lower level, said shroud having a downwardly extending wall with perforations and a surrounding chamber of generally U-shaped cross section for collection of popped corn which leaves the open top pot, air passages in said base connecting external air to the perforations in said wall for flow of external air through the collected popped corn, a circulating air fan in said base driven by said motor for inducing said air flow, and an open top storage bin removably attached to said shroud and partially overlying the pot perimeter for guiding popped corn exiting the pot to said chamber while permitting moisture-laden air to leave the corn popper.
Claim 3
Dependent Claim
112 words
A corn popper having a relatively shallow open top pot, stirring means within said pot and overlying the bottom of said pot to contact corn kernels resting on said bottom, a bin surrounding said pot to collect popped corn, a flexible lid covering said pot and having a perimeter resting on the top edge thereof, and means mounting a central part of said lid for upward movement to permit elevation of said central part away from a top edge of the pot as the popped corn volume increases to permit release of air from the pot while a major part of the lid perimeter rests on the top edge of the pot.
Claim 4
Dependent Claim
112 words
A corn popper having a relatively shallow open top pot, stirring means within said pot and overlying the bottom of said pot to contact corn kernels resting on said bottom, a bin surrounding said pot to collect popped corn, a flexible lid covering said pot and having a perimeter resting on the top edge thereof, and means mounting a central part of said lid for upward movement to permit elevation of said central part away from a top edge of the pot as the popped corn volume increases to permit release of air from the pot while a major part of the lid perimeter rests on the top edge of the pot.
Claim 5
Dependent Claim
56 words
A corn popper as defined in claim 2 wherein said flexible lid includes two wing sections pivotally connected together by a pivot pin, and a pair of elongate slots in a wall of the pot each receiving an end of the pivot pin whereby the pivot pin may move upwardly as the popped corn volume increases.
Claim 6
Dependent Claim
43 words
A corn popper as defined in claim 3 wherein each of said wing sections has a part thereof in contact with the top edge of the pot provided with weight-adding means to maintain said contact as the central part of the lid rises.
Claim 7
Dependent Claim
55 words
A corn popper as defined in claim 4 wherein each of said wing sections has a downwardly-angled part and a recessed periphery adjacent thereto to have said parts loosely receive the pivot pin and permit the pivot pin to normally be positioned in said elongate slots beneath the level of the top of the pot.
Claim 8
Dependent Claim
47 words
A corn popper as defined in claim 5 wherein said normal position of the pivot pin is above the lower end of said elongate slots, the pivot pin has its ends extending beyond the pot for manual depression thereof to cause upward pivoting of the wing sections.
Claim 9
Dependent Claim
28 words
A corn popper as defined in claim 6 wherein the pivot pin is removable from the wing sections to separate the last-mentioned parts from the pot for cleaning.
Claim 10
Dependent Claim
45 words
A corn popper as defined in claim 4 including a bin surrounding said pot for collecting popped corn after the popped corn rises in the pot to pivot said wing sections about said pivot pin to permit outward movement of popped corn into the bin.
Claim 11
Dependent Claim
15 words
A corn popper as defined in claim 8 wherein said bin and pot are round.
Claim 12
Dependent Claim
44 words
A corn popper as defined in claim 8 wherein said pot is round and said bin is generally rectangular and having a first dimension axially of the pivot pin and a second longer dimension normal to the first dimension to receive the popped corn.
Claim 13
Dependent Claim
15 words
A corn popper as defined in claim 8 including power-operated stirring means in said pot.
Claim 14
Dependent Claim
35 words
A corn popper as defined in claim 8 wherein said bin has a top opening and part thereof surrounding the top opening curved to downwardly deflect popped corn as it flies out of the pot.
Claim 15
Dependent Claim
67 words
A corn popper as defined in claim 8 including stirring means in said pot, a heating element secured to the pot, a base removably supporting said pot, drive means for said stirring means including a drive motor in said base and a separable drive connection, and a quick disconnect electrical coupling between said heating element and said base whereby said pot may be separated from said base.
