A deep fat fryer comprising: a vessel defining a smoothed walled chamber proportioned to receive cooking oil and chicken serving pieces to be cooked in the approximate ratio of two to one, a drain opening at the bottom of said vessel, valve means for opening and closing said drain opening, a removable cover for closing off the top of said vessel, means for clamping said cover in closed relation to the vessel for cooking the chicken serving pieces under pressurized conditions, heater means about said vessel and spaced at a level above the level of the bottom of said vessel for heating cooking oil received in the chamber to a temperature range for cooking chicken serving pieces received in the oil when the oil is in the chamber, said heater means being exterior of said chamber, and filter means within said chamber and between the level of said heater means and the level of said vessel bottom for filtering cooking oil drained from said vessel before it passes through said valve means, and disposed to permit solids in the oil collect on its upper side, said filter means comprising a filter unit extending across said chamber and including filter paper through which the cooking oil is to pass on opening of said valve means to filter the cooking oil, and means for applying a differential pressure on the cooking oil when said valve means is opened for inducing cooking oil flow through said filter paper, said heater means being positioned in the spaced relation relative to said filter means to avoid charring of the solids collecting on the filter means when the oil is heated to said temperature range and yet drive off moisture from said paper to permit said filtering of the oil through said paper on opening of said valve means and application of the differential pressure to the cooking oil.

A deep fat fryer comprising: a vessel defining a smoothed walled chamber proportioned to receive cooking oil and chicken serving pieces to be cooked in the approximate ratio of two to one, a drain opening at the bottom of said vessel, valve means for opening and closing said drain opening, a removable cover for closing off the top of said vessel, means for clamping said cover in closed relation to the vessel for cooking the chicken serving pieces under pressurized conditions, heater means about said vessel and spaced at a level above the level of the bottom of said vessel for heating cooking oil received in the chamber to a temperature range for cooking chicken serving pieces received in the oil when the oil is in the chamber, said heater means being exterior of said chamber, and filter means within said chamber and between the level of said heater means and the level of said vessel bottom for filtering cooking oil drained from said vessel before it passes through said valve means, and disposed to permit solids in the oil collect on its upper side, said filter means comprising a filter unit extending across said chamber and including filter paper through which the cooking oil is to pass on opening of said valve means to filter the cooking oil, and means for applying a differential pressure on the cooking oil when said valve means is opened for inducing cooking oil flow through said filter paper, said heater means being positioned in the spaced relation relative to said filter means to avoid charring of the solids collecting on the filter means when the oil is heated to said temperature range and yet drive off moisture from said paper to permit said filtering of the oil through said paper on opening of said valve means and application of the differential pressure to the cooking oil.
Claim 3
Dependent Claim

The fryer set forth in claim 1 wherein: said filter unit further comprises a pair of upper and lower foraminous plates between which said filter paper is positioned, with said filter unit upper plate being disposed about three-fourths of an inch below the level of said heater means.
Claim 4
Dependent Claim
213 words
A deep fat fryer comprising: a vessel defining a smoothed walled chamber proportioned to receive cooking oil and chicken serving pieces to be cooked in the approximate ratio of two to one, a drain opening at the bottom of said vessel, valve means for opening and closing said drain opening, a removable cover for closing off the top of said vessel, means for clamping said cover in closed relation to the vessel, heater means about said vessel and spaced above the bottom thereof for heating cooking oil received therein, said heater means being exterior of said chamber, and filter means between said heater means and said vessel bottom for filtering cooking oil drained from said vessel before it passes through said valve means, and disposed to permit solids in the oil collect on its upper side, said filter means including filter paper through which the cooking oil is to pass to filter same, said heater means being positioned relative to said filter means to avoid charring of the solids collecting on the filter means and yet drive off moisture from said paper to permit filtering through said paper, and means for supplying gas under pressure to said chamber for draining the oil from the vessel through said filter paper under fluid pressure conditions.
Claim 5
Dependent Claim
213 words
A deep fat fryer comprising: a vessel defining a smoothed walled chamber proportioned to receive cooking oil and chicken serving pieces to be cooked in the approximate ratio of two to one, a drain opening at the bottom of said vessel, valve means for opening and closing said drain opening, a removable cover for closing off the top of said vessel, means for clamping said cover in closed relation to the vessel, heater means about said vessel and spaced above the bottom thereof for heating cooking oil received therein, said heater means being exterior of said chamber, and filter means between said heater means and said vessel bottom for filtering cooking oil drained from said vessel before it passes through said valve means, and disposed to permit solids in the oil collect on its upper side, said filter means including filter paper through which the cooking oil is to pass to filter same, said heater means being positioned relative to said filter means to avoid charring of the solids collecting on the filter means and yet drive off moisture from said paper to permit filtering through said paper, and means for supplying gas under pressure to said chamber for draining the oil from the vessel through said filter paper under fluid pressure conditions.
Claim 6
Dependent Claim
271 words
A deep fat fryer comprising: a vessel defining a smoothed walled chamber proportioned to receive cooking oil and chicken serving pieces to be cooked in the approximate ratio of two to one, a drain opening at the bottom of said vessel, valve means for opening and closing said drain opening, a removable cover for closing off the top of said vessel, means for clamping said cover in closed relation to the vessel, vessel, heater means about said vessel and spaCed above the bottom thereof for heating cooking oil received therein, said heater means being exterior of said chamber, and filter means between said heater means and said vessel bottom for filtering cooking oil drained from said vessel before it passes through said valve means, and disposed to permit solids in the oil collect on its upper side, said filter means including filter paper through which the cooking oil is to pass to filter same, said heater means being positioned relative to said filter means to avoid charring of the solids collecting on the filter means and yet drive off moisture from said paper to permit filtering through said paper, an large mesh wire basket means proportioned to substantially complement the internal horizonal cross sectional configuration of said chamber and adapted to receive the chicken to be cooked for immersion in the cooking oil, said basket means including retractable laterally extending projections that retract on insertion of said basket means in the chamber and extend on withdrawal of said basket means therefrom whereby said basket means may be temporarily rested on top of the vessel to permit excess oil to drain therefrom.
Claim 7
