     The lid release adjustment assembly includes a release support member having a threaded hole therein to receive an adjustment screw member having an outer hemispherical end section. The adjustment screw member is selectively movable axially within the threaded hole to adjust pressure releasing features of the main trip lid assembly. 
     The actuator ball assembly includes a ball support member secured to a top surface of the main arcuate housing body of the trip lid housing assembly and extended outwardly therefrom having a ball member mounted thereon. 
     The ball member is operable to engage the trip slide member within the circular ball support section for proper operation thereof during a trip release function of the main trip lid assembly and positioned diametrically opposite the lid release adjustment assembly. 
     The restraining assembly includes a chain member having one end connected by an anchor clamp member to the ball support member and, at an opposite end, is secured to a circular ring member. 
     The ring member is operable to be placed about the main slide body so as to limit the pivotal movement of the main trip lid assembly when in a pressure released condition. 
     A second embodiment of the overflow cooking pot assembly is an overflow cooking pot and adapter assembly utilizing a conventional support pan member and having a fluid overflow adapter assembly mounted on the support pan member plus the previously described main trip lid assembly used therewith. 
     The fluid overflow adapter assembly includes an overflow rim assembly used with an O-ring member operable to be placed within an inner, upwardly, outwardly inclined side wall of the conventional support pan member. 
     The overflow rim assembly includes an inner tapered wall section integral with a flat horizontal section which, in turn, is integral with an arcuate wall section and having an upper lid support rim section integral therewith. 
     The fluid overflow adapter assembly is provided with a lid support and actuator assembly as described for the first embodiment which is mounted on the flat horizontal section of the overflow rim assembly. 
     Additionally, the overflow rim assembly is provided with a handle assembly connected to the upper lid support rim section. The inner tapered wall section is provided on a lower exterior portion thereof with an O-ring groove to receive the O-ring member therein. The O-ring member extends outwardly from the inner tapered wall section so as to engage an inner side wall surface of the conventional support pan member when mounted therein in a sealing manner. 
     The overflow cooking pot and adapter assembly includes the previously described main trip lid assembly which is operable to be mounted within the overflow rim assembly and cooperates with the flat horizontal section therein for proper operation. 
     In a third embodiment of the overflow cooking pot assembly, a concave support pan member is used with a support O-ring member connected thereto. The concave support pan member has an arcuate outwardly concave side wall integral with an upper support rim section. 
     The upper support rim section is adapted to receive the support O-ring member mounted thereon so as to provide a sealing function with the fluid overflow adapter assembly described in the second embodiment, being the overflow cooking pot and adapter assembly. 
     The support O-ring member would then seal with an outer surface of the inner tapered wall section of the fluid overflow adapter assembly. This permits operation with the outwardly concave support pan member which would not be possible without the third embodiment of this invention.

The arcuate side wall 34 has, at an upper edge thereof, a lid support rim portion 36 to support the outer lid assembly 16 thereon. 
     The handle assembly 24 includes a finger handle member 38 on one side of the lid support rim portion 36 and a lateral handle member 40 diametrically opposed therefrom. 
     The finger handle member 38 and the lateral handle member 40 are jointly operable for grasping and conveying the entire main support pan member 14. 
     The outer lid assembly 16 is provided with 1) a main arcuate body member 42 having a peripheral outer seal lip section 44 engagable with the lid support rim portion 36 when mounted on the main support pan member 14; 2) a grasp knob member 46 positioned centrally of an upper, outer portion of the main arcuate body member 42; 3) a drainage opening 48 in one portion of the main arcuate body member 42; and 4) a cover member 50 mounted across the drainage opening 48. 
     The cover member 50 comprises a screen member 52 which allows liquid to flow from the main support pan member 14 when draining fluid therefrom while retaining food product within the main support pan member 14. 
     The main trip lid assembly 18 includes 1) a trip lid housing assembly or lid support ledge or lid support means 54; 2) a lid support and actuator assembly 56 connected to the horizontal section 32 of the fluid overflow section 22 of the main support pan member 14; 3) a lid release adjustment assembly or side wall abutting means or lid brace nipple 58 connected to the trip lid housing assembly 54; 4) an actuator ball assembly obtrusion or protrusion means 60 connected to the trip lid housing assembly 54 positioned diametrically opposite the lid release adjustment assembly 58; and 5) a restraining assembly 62 connected to the actuator ball assembly 60 and releasably connectable to the lid support and actuator assembly 56 in a manner to be explained. 
     The trip lid housing assembly 54 includes 1) a main arcuate housing body 64 having an outer peripheral and integral actuator rim assembly 66; and 2) a knob member 67 positioned in an upper central portion of an outer surface of the main arcuate housing body 64. 
     The actuator rim assembly 66 is provided with a projecting support section 68 and an opposed weighted support section 70. The projecting support section 68 is operable to rest on the trip lid support rim portion 30 of the main support pan member 14 as noted in FIG. 5. 
     The weighted support section 70 and the ball actuator assembly 60 are operable to counter-balance the weight of the projecting support section 68 so that the entire trip lid housing assembly 54 will move to a pressure trip release condition as noted in FIG. 11 for reasons to be explained. 
     As noted in FIG. 6, the lid support and actuator assembly 56 includes a trip slide member 72 having an adjacent trip stabilizer member 74 which are jointly secured to the flat horizontal section 32 of the main support pan member 14 (FIG. 1). 
     The trip slide member 72 is provided with a main slide body 76 integral with an anchor section 78 and formed with an arcuate semi-circular ball support section or surface 80. The ball support section 80 curves downwardly and inwardly toward the side wall 28 of the main support pan member 14. A lower edge of the ball support section 80 is aligned with an inner surface of the side wall 28 for proper trip actuated movement of the main trip lid assembly 18 as will be noted. 
     The trip stabilizer member 74 includes a ball support plate 82 having a semi-circular indentation 84 extended in a generally horizontal plane. The semi-circular indentation 84 is to receive a portion of the actuator ball assembly 60 when placing the main trip lid assembly 18 in an inactive or non-release pressurized condition as will be explained. 
     As noted in FIG. 11, the lid release adjustment assembly 58 includes a release support member 86 having an adjustment screw member 88 connected thereto. More particularly, the release support member 86 has a threaded hole 90 to receive the adjustment screw member 88 therein which is preferrably a set screw type having an outer hemispherical end section 96 and an upper slot 97 to receive a head of a screwdriver for adjustment thereof. 
     The hemispherical end section 96 is important and operable to contact an inner surface of the side wall 28 of the main support pan member 14 and provides an infinite adjustment pressure release feature. 
     As shown in FIG. 6, the actuator ball assembly 60 includes a ball support member 98 anchored to the main trip lid assembly 18 and having an integral ball member 102 positioned on an outer end of the ball support member 98. 
     The ball member 102 is operable to engage the trip slide member 72 when in a pressure actuated trip release condition during a cooking operation or to be placed within the semi-circular indentation 84 of the trip stabilizer member 74 when in a non-release pressurized condition. 
     The restraining assembly 62 includes a chain member 104 secured by an anchor clamp 106 to the ball support member 98 and having a ring member 108 connected to an outer end of the chain member 104 (FIG. 6). 
     The ring member 108 is operable to be releasably mounted about an upper portion of the main slide body 76 of the trip slide member 72 to limit downward pivotal movement of the entire main trip lid assembly 18 as shown in FIG. 11. 
     In a second embodiment of this invention as shown in FIGS. 8-11 and 13, an overflow cooking pot and adapter assembly 112 is provided with 1) a conventional support pan member 114; 2) a fluid overflow adapter assembly 116 mountable on the conventional support pan member 114; 3) a main trip lid assembly 18 mounted on the fluid overflow adapter assembly 116; and 4) an outer lid assembly 16 mountable on the fluid overflow adapter assembly 116. 
     The conventional support pan member 114 is provided with a bottom wall 118 having an integral, upright, outwardly inclined side wall 120. The handle assembly 24 connected to the upper edge of the side wall 120. The handle assembly 24 is as previously described having a finger handle member 38 cooperating with the lateral handle member 40 for ease of movement of the conventional support pan member 114. 
     The fluid overflow adapter assembly 116 includes an overflow rim assembly 122 having an O-ring member or flexible annular support member 124 of various sizes connected thereto. The overflow rim assembly 122 includes an inner tapered wall section 126 integral with a horizontal section 128 that is integral with an upwardly and outwardly extended arcuate wall section 130 which, in turn, has an upper lid support rim section 132 to support the outer lid assembly 16 thereon. 
     The inner tapered wall section 126 is provided with an outer O-ring groove or flexible annular support member groove 134 and an inner overflow support rim 136 to receive the main trip lid assembly 18 thereon. 
     The upper lid support rim section 132 is provided with a previously described handle assembly 24 having a finger handle member 38 and a lateral handle member 40 for ease of removal of the fluid overflow adapter assembly 116 from the conventional support pan member 114 as noted in FIG. 13. 
     The main trip lid assembly 18 is as previously described having 1) the trip lid housing assembly 54; 2) the lid support and actuator assembly 56; secured to the overflow rim assembly 122 3) the lid release adjustment assembly 58; 4) the actuator ball assembly 60; and 5) the restraining assembly 62. These elements are operable in a manner to achieve the pressure release cooking condition as noted in FIGS. 6 and 7 or the optional non-release cooking condition of FIGS. 8 and 9. 
     The pressure release cooking condition of the main trip lid assembly 18 in the second embodiment of the overflow cooking pot and adapter assembly 112 is as noted in FIG. 10 except the overflow adaptor assembly 116 would be mounted in the conventional support pan member 114 as shown in FIG. 11. 
     In a third embodiment of this invention, the main trip lid assembly 18 in conjunction with the fluid overflow adapter assembly 116 is utilized on a concave support pan member 142 used in conjunction with a support O-ring member 144, which can be of various sizes, as shown in FIG. 12. 
     More specifically, the concave support pan member 142 has an arcuate side wall 148 with an upper support rim section 150. The fluid overflow adapter assembly 116 would not properly fit and seal with an upper edge of the arcuate side wall 148 of the concave support pan member 142 without the side of the support O-ring member 144. 
     As noted in FIG. 12, the support O-ring member 144 has a main ring body 152 with an outer circular surface or diameter 154 of selected various sizes and an inner slot section 156. The inner slot section 156 is operable to be snapped about an outer periphery of the upper support rim section 150 of the concave support pan member 142 (FIG. 12). 
     Therefore, in this third embodiment, it is obvious that when the fluid overflow adapter assembly 116 is inserted into the concave support pan member 142, an outer surface of the tapered wall section 126 would engage an inner surface of the outer circular surface 154 of the support O-ring member 144 to achieve sealing engagement therewith. 
     USE AND OPERATION OF THE INVENTION 
     In the use and operation of the overflow cooking pot assembly 12 of this invention, it is noted that the main support pan member 14 can be filled with a liquid and food product for a cooking operation in an adjustable, pressure cooking situation. 
     The next step is to place the main trip lid assembly 18 in the position as shown in FIG. 2 with the ball member 102 mounted on the arcuate ball support section 80 of the trip slide member 72 (see FIGS. 6 and 7). 
     then, on use of the restraining assembly 62, the ring member 108 placed about an upward portion of the main slide body 76 of the trip slide member 72 as shown in FIG. 6. 
     At this time or prior to placing the main trip lid assembly 18 on the main support pan member 14, the lid release adjustment assembly 58 can be adjusted through the use of a screwdriver to rotate the adjustment screw member 88 axially within the threaded hole 90 of the release support member 86. This adjustment movement of the adjustment screw member 88 operates to increase and decrease contact by the outer hemispherical end section 96 with an inner, upper wall surface of the side wall 28. 
     If the adjustment screw member 88 is moved downwardly with the threaded hole 90 with a point of contact of the outer hemispherical section 96 with the side wall 28, this would increase the required cooking pressure within the main support pan member 14 to release the main trip lid assembly 18 to a trip lid release condition as shown in FIG. 11. This point of contact is important for the infinite, adjustable pressure release feature of this invention. 
     On cooking with the combination of liquid and food product within the main support pan member 14, it is noted that, on increasing internal cooking pressure to a predetermined amount, the pressure lifts the adjustment screw 88 disengaging its contact from the side wall 28. Upon the removal of this support, the weighted support section 70 of the actuator rim assembly 66 pulls the ball member 102 mounted on the projecting support section 68 down the slide surface of the arcuate circular ball support section 80 of the slid member 72 of the lid support and actuator assembly 56. The curvature of the slide surface pries the trip lid housing assembly 54 onto the cooperating horizontal section 32 of the fluid overflow section 22 of the main support pan member 14. This cause the trip lid housing assembly 54 to pivot as noted by an arrow 160 from the lid support rim portion 30 as noted in FIG. 5 to cause an immediate cooling influence on boiling contents in the main support pan member 14. 
     This upward movement would then achieve the condition of the main trip lid assembly 18 as noted in FIG. 11 with the downward movement thereof indicated by an arrow 162 in FIG. 11 in either the first or second embodiments of the invention. This downward movement is limited due to the length of the chain member 104 on the restraining assembly 62 to prevent the trip lid housing assembly 54 from contacting the food product within the main support pan member 14 being used. 
     On moving the main trip lid assembly 18 to the aforementioned trip release condition, it is obvious that any pressure build-up in the main support pan member 14 would be harmlessly released to the atmosphere and an immediate cooling influence of cooking contents in the main support pan member 14 is achieved. 
     It is noted that, after cooking of the food product in the overflow cooking pot assembly 12, the handle assembly 24 on the main support pan member 14 and grasping of the knob member 46 on the outer lid assembly 16 can be utilized for tipping of the entire enclosed structure to drain the fluid contained within the main support pan member 14 outwardly through the drainage opening 48 and through the screen member 52 in the outer lid assembly 16 to act as a strainer for cooking and then subsequent fluid draining function of this invention. 
     In certain cases, it may be desirable to place the main trip lid assembly 14 in a non-release pressurized or inactive condition. This is illustrated in FIG. 9 whereupon the the ball member 102 of the actuator ball assembly 60 is placed within the semi-circular indentation 84 on the trip stabilizer member 74. In this condition, the main trip lid assembly 18 cannot move to the pivoted pressure release condition of FIG. 11 so as to operate as a conventional lid assembly sealing the interior of the main support pan member 14 for a conventional cooking operation in a non-release pressurized condition. 
     On use of the second embodiment as noted in FIGS. 10 and 11, the overflow cooking pot and adaptor assembly 112 is similarly operably as previously described for the overflow cooking pot assembly 12. In this second embodiment, the conventional support pan member 114 can be sued, not requiring the specially designed main support pan member 14 in the first embodiment being the overflow cooking pot assembly 12. 
     More specifically, as noted in FIG. 10, the fluid overflow adapter assembly 116 is positioned over a top opened area of the conventional support pan member 114 and lowered to the position of FIG. 11. On lowering into the conventional support pan member 114, the O-ring member 124 is operable to engage and seal with an inner surface of the side wall 120 of the conventional support pan member 114. O-ring members 124 of various diameters can be selectively used in order to properly seal with the side wall 120 of different internal sizes of conventional support pan members 114. 
     As noted in FIG. 12 in the third embodiment of this invention, the fluid overflow adapter assembly 116, in conjunction with the main trip lid assembly 18, is utilized with the concave support pan member 142 having the support O-ring member 144 mounted thereon. 
     When the fluid overflow adapter assembly 116 is lowered into the concave support pan member 142 similar to that shown in FIG. 10, an outer tapered wall section 126 of the overflow rim assembly 122 will contact an inner surface of the support O-ring member 144 to seal therewith. Support O-ring members 144 of various diameters can be selectively used in order to properly seal with the outer tapered wall section 130 of the overflow rim assembly 122. 
     In this assembled condition of the fluid overflow adapter assembly 116 in conjunction with the main trip lid assembly 18, the third embodiment will then operate in a manner as previously described for the first and second embodiments being operable 1) in an adjustable excess cooking pressure condition within the concave support pan member 142; and 2) in the non-release pressurized condition on interconnection of the actuator ball assembly 60 with the trip stabilizer member 74. 
     The overflow cooking pot assembly and the embodiment of the overflow cooking pot and adapter assembly of this invention is economical to manufacture; adjustable in operation as to release of a given pressure build-up within a cooking support pan member; easy to use; and substantially maintenance free. 
     While the invention has been described in conjunction with preferred specific embodiments thereof, it will be understood this description is intended to illustrate and not to limit the scope of the invention, which is defined by the following claims.
