     BACKGROUND OF THE INVENTION 
     This invention relates generally to the field of resource recycling and more specifically to a mobile device for recovery and on site storage of used cooking oil. There are numerous business establishments, in example restaurants, hospitals, assisted living facilities, schools, nursing homes, which must provide preparation and serving of food. Such institutions invariably make use of deep fat fryers to satisfy the demands of their customers for particular types of food. 
     Deep fat fryers utilize cooking oil which is heated in vats ranging in size from a few cups to hundreds of gallons. Such fryers are very effective but their usage does give occasion to serious inconveniences. In example, the cooking oil quality in the fryers must be constantly monitored and when it is no longer usable, must be removed, replaced, and disposed of. Typically, when a fryer is to be emptied, the cooking oil must be allowed to cool down from its maximum temperature, usually approximately 350° F., to a temperature that would not be harmful to one performing the removal task. In the case of larger fryers, this cooling can take up to twelve hours, during which time the fryer is out of service. Most fryers comprise means to remove spent cooking oil such as drains or pumps which pump cooking oil out of the vats through conduits and into a vessel. Said vessel is then carried to a storage bin, generally located outside the building housing the facility, and deposited therein. The process typically requires actions on the part of the employee performing the cooking oil removal and transfer to storage bin task which expose him to possible and very probable contact with the cooking oil. In example, the cooking oil may splash, the cooking oil draining out of a fryer may fall on the employee, the employee may accidentally misdirect a stream of cooking oil pumped out of a fryer through a hose so that it falls on himself or someone else. Further, the external location of the storage bin requires the employee to exit the building which he will invariably take advantage of to loiter. 
     Then, once the cooking oil is removed from the fryer vat, any residue of cooking oil and/or organic remnants remaining in the bottom of said vat must be removed. If the vat is not sufficiently cleaned of such dregs, the new replacement cooking oil may be contaminated resulting in poor food quality and reduced life span of the cooking oil. Such residue will also cause uneven heating of the cooking oil and resultant improper cooking. 
     The whole process, accomplished with extant technology, tends to be very messy and facets of it such as cleaning out residue can be difficult. Also, the external storage bins tend to be very unsanitary and unsightly as cooking oil deposited therein tends to be spilt. 
     Now that modern technological advances have rendered used cooking oil a valuable commodity as a base for fuel for internal combustion engines, sale of used cooking oil can be of significant financial benefit to fat fryer operators. It is therefore to their advantage to store used cooking oil and efficiently transfer the cooking oil to a buyer who generally transfers the cooking oil to a tank truck. 
     The instant art provides a means to safely remove cooking oil from a fryer without having to wait for the cooking oil to cool, provides a means of storage which is movable from the collection point at the fryer to an out of the way place within a building and is movable outside the building to a disposal tank truck. This removal of the storage device can be performed by the driver of the truck so that employees are free for other tasks. 
     The instant art also provides means to store and readily access implements to remove dregs from the vat, such implements as vacuum cleaner, cleansing pads, power polishers, brushes, gloves, etc.

     DETAILED DESCRIPTION 
     Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner. 
     It is well known in myriad arts that devices such as pumps and power tools require power cords, comprise on/off switches, and provide means to fix in inoperative orientation said power cords. The functions and manners of usage of such devices is also well known. Therefore the employment of same will not be described in detail unless necessary to teach the instant art. Also well-known are sundry types of fittings and/or couplings which removably attach one conduit to another and/or removably attach a conduit to a fixture, especially an inlet or exit port to any type of manifold or vessel. Such devices will not be described in detail unless necessary to teach the instant art. 
       FIG. 1  shows a mobile device for recovery and on site storage of used cooking oil ( 100 ) comprising a cooking oil tank ( 102 ) having a top ( 103 ), sides ( 109 ), and a floor ( 111 ). Disposed on the top ( 103 ) are a cooking oil filter inlet port ( 144 ) having walls ( 147 ) extending from the top ( 103 ) and a removable and replaceable cooking oil filter inlet port cap ( 146 ). The top ( 103 ) also comprises a cooking oil withdrawal port ( 140 ) having a removable and replaceable cooking oil withdrawal port cap ( 142 ). In addition, the top ( 103 ) also has a means to determine the cooking oil level ( 128 ) in the tank ( 102 ), in example a dip stick ( 130 ). Also located on the top is a cooking oil tank fill port ( 116 ). 
     Attached to a cooking oil tank side ( 109 ) is a pump housing ( 104 ) having a cooking oil tank fill hose ( 114 ) which extends to the cooking oil tank fill port ( 116 ) and is removably connected thereto by a fitting ( 156 ). Also extending from the pump housing ( 104 ) is a cooking oil extraction conduit ( 110 ) which is removably connected to an intake wand ( 118 ) by a fitting ( 156 ) and a handle ( 105 ). The intake wand ( 118 ) has a handle ( 120 ) and is removably held in convenient, inoperative position by a wand holster ( 126 ). The intake wand ( 118 ) has an inlet ( 122 ) which may comprise an intake wand inlet cooking oil filter ( 124 ). The device ( 100 ) may have conduit brackets ( 158 ) to hold the cooking oil extraction conduit ( 110 ) in inoperative position. 
     Extending from a cooking oil tank side ( 109 ) is an accessory tray ( 170 ). 
       FIG. 17  shows that the accessory tray ( 170 ) may house in accessible disposition such items as a vacuum ( 176 ) having an attachment ( 180 ) and a hose ( 178 ), brushes ( 174 ), an eye protection device ( 171 ), gloves ( 172 ), a powered polisher ( 182 ), cleansing pads ( 184 ), and cleanser ( 185 ), all of whose purposes will be recited presently. 
     Extending from the tank floor ( 111 ) are casters located at optimal positions to allow movement of the device ( 100 ) by applying force to a device push/pull handle ( 164 ) which extends from cooking oil tank sides ( 109 ). The casters ( 132 ) may have locking means ( 138 ) to prevent unwanted movement of the device ( 100 ). The casters ( 132 ) may be fixed type ( 134 ) as shown in  FIG. 2  or a movable or swivelable type ( 136 ) as shown in  FIG. 2A . 
       FIG. 7  shows that the pump housing ( 104 ) comprises a pump ( 106 ) of any type suitable to move cooking oil ( 101 ), though a gear pump is preferred, which may be removably fixed in said housing ( 104 ) by any suitable, known means. From the pump ( 106 ), extends a pump inlet removably attached by fitting ( 156 ) to a pump inlet conduit ( 108 ) which extends through the pump housing ( 104 ) where it is removably joined by fixture ( 156 ) to a cooking oil extraction conduit ( 110 ) removably joined to the intake wand ( 118 ). Also seen is that a pump outlet ( 168 ) extends from the pump ( 106 ) and is removably fixed by fitting ( 156 ) to a pump outlet conduit ( 112 ) which extends through the pump housing ( 104 ) where it is removably connected by fitting ( 156 ) to a cooking oil tank fill hose ( 114 ) which is removably fixed to the cooking oil tank fill port ( 116 ) by fitting ( 156 ). 
       FIG. 1 ,  FIG. 7A , and  FIG. 7B  show that the intake wand ( 118 ) may comprise the intake wand inlet cooking oil filter ( 124 ) having a sieve portion ( 125 ) attached proximal the intake wand inlet ( 122 ) with the intake wand ( 118 ) extending into the interior of the intake wand inlet cooking oil filter ( 124 ) through the intake wand inlet cooking oil filter port ( 123 ). Said intake wand inlet cooking oil filter ( 124 ) may be attached to the intake wand ( 118 ) by any suitable known means. In example,  FIG. 7B  depicts the intake wand ( 118 ) comprising a substantially planar intake wand flange ( 119 ) extending from the intake wand ( 118 ) so that when the intake wand is extended into the intake wand inlet cooking oil filter ( 124 ) through the intake wand inlet cooking oil filter port ( 123 ), the intake wand flange will communicate with the intake wand inlet cooking oil filter ( 124 ) thusly arresting the insertion of the intake wand ( 118 ) and positioning the intake wand inlet ( 122 ) within the interior of the intake wand inlet cooking oil filter ( 124 ). In addition, the intake wand inlet cooking oil filter ( 124 ) may have intake wand inlet cooking oil filter stays ( 127 ) positioned on opposite sides of the intake wand ( 118 ) inserted into the intake wand inlet cooking oil filter ( 124 ). Stay clips are positioned on the intake wand inlet cooking oil filter ( 124 ) so that when the intake wand inlet cooking oil filter stays are pivoted, said stays ( 127 ) will pass over the intake wand flanges and engage the stay clips ( 129 ). The stay clips ( 129 ) will hold the intake wand inlet oil filter stays ( 127 ) fast thus fixing the intake wand flange ( 119 ) between said stays ( 127 ) and the intake wand inlet cooking oil filter ( 124 ) and attaching the filter ( 124 ) to the intake wand ( 124 ) in operative disposition. The intake wand inlet cooking oil filter stays are pivotable in opposite directions, as indicated by double headed arrows, and the stay clips ( 129 ) are releasable. Therefore, the intake wand inlet cooking oil filter ( 124 ) may be attached, removed from, and/or reattached to the intake wand ( 118 ). 
     One skilled in the art will readily appreciate that when the pump ( 106 ) is engaged, cooking oil may be taken up through the intake wand inlet ( 122 ), after being drawn through the intake wand inlet filter sieve portion ( 125 ) and transferred through the intake wand ( 118 ), the cooking oil extraction conduit ( 112 ), the pump inlet conduit ( 108 ), the pump inlet ( 166 ), pump ( 106 ), pump outlet ( 168 ), pump outlet conduit ( 112 ), cooking oil tank fill conduit ( 114 ), and cooking oil tank fill port ( 116 ) and into the cooking oil tank ( 102 ) as seen in  FIG. 16  where cooking oil ( 101 ) is shown entering the cooking oil tank ( 102 ) after passing through the cooking oil tank fill port ( 116 ). Also appreciated will be that the conduits ( 110 ,  108 ,  112 ,  114 ) may be flexible and may comprise food grade hoses. 
       FIG. 17  shows that the accessory tray ( 170 ) may conveniently and/or readily accessibly house various items to facilitate cooking oil recovery and/or fryer cleaning subsequent to cooking oil removal and prior to new cooking oil addition. In example, seen are eye protection device ( 171 ), brushes ( 174 ), gloves ( 172 ), vacuum ( 176 ), vacuum hose ( 178 ), vacuum hose attachment ( 180 ), power polisher ( 182 ), cleaning pads ( 184 ), cleaning compound ( 185 ). Also, we will understand that any other items deemed necessary by one skilled in the art may be disposed in said accessory tray ( 170 ). 
       FIG. 3 ,  FIG. 3A ,  FIG. 3B , and  FIG. 3C  show that the cooking oil port filter ( 148 ) comprises cooking oil port filter walls ( 190 ), a cooking oil port filter floor ( 192 ), and a cooking oil port filter aperture ( 194 ) oriented opposite the floor ( 192 ). Said elements comprise an essentially prismatic configuration and cooking oil port filter flanges ( 154 ) extend from cooking oil port filter walls ( 190 ) proximal the cooking oil port filter aperture ( 192 ). Also noted is that portions of the cooking oil port filter walls ( 190 ) and portions of the cooking oil port filter floor ( 192 ) comprise cooking oil port filter sieve portions ( 149 ). 
       FIG. 4  shows an exploded view of that portion of the tank ( 102 ) and tank top ( 103 ) comprising the cooking oil tank inlet filter port ( 144 ), the cooking oil inlet port filter ( 147 ), and the cooking oil inlet port filter cap ( 146 ). Noted is that the cooking oil inlet filter port comprises walls ( 147 ) extending upward from the tank ( 102 ) and it will be understood that said walls ( 147 ) define an aperture ( 145 ). Also seen is that the cooking oil port filter ( 148 ) is dimensioned to extend with minimum clearance necessary into the cooking oil port filter port ( 144 ) through its aperture ( 145 ). Also seen is a cooking oil inlet filter port cap ( 146 ) dimensioned to communicate with the cooking oil port filter ( 148 ) to occlude the cooking oil port filter aperture ( 145 ). 
       FIG. 5  shows that the cooking oil port filter ( 148 ) extends into the tank ( 102 ) through the cooking oil inlet filter port ( 144 ) whereupon the cooking oil port filter flanges ( 154 ) will rest upon cooking oil inlet filter port walls ( 147 ) thusly arresting progress of the cooking oil port filter ( 148 ) into the cooking oil inlet filter port ( 144 ) thusly fixing the cooking oil port filter ( 148 ) in operative position. Additionally shown is that the cooking oil inlet filter port cap ( 146 ) will rest with minimum clearance upon the cooking oil port filter flanges ( 154 ) and the cooking oil port filter walls ( 190 ). 
     In consideration of  FIG. 1 ,  FIG. 7 , and  FIG. 8 , employment of the device ( 100 ) in an embodiment may be described. The device ( 100 ) is moved from its place of stowage, after disengaging the caster locks ( 132 ), to a position proximal a cooking oil fryer ( 200 ) having cooking oil vats ( 202 ) so that the length of the cooking oil extraction conduit ( 110 ) allows functional use of the intake wand ( 118 ). The caster locks ( 132 ) may then be re-engaged if deemed necessary for convenience and/or safety. The intake wand ( 118 ) is then removed from the wand holster ( 126 ) and the cooking oil extraction conduit ( 110 ) is disengaged as necessary from brackets ( 158 ) whereupon the intake wand ( 118 ) is positioned, by usage of the handle ( 120 ) if needed, into the fryer vat ( 202 ) below the level of cooking oil ( 101 ). The pump ( 106 ) is then engaged and cooking oil ( 101 ) is drawn into the intake wand ( 118 ) through intake wand inlet ( 122 ). The cooking oil ( 101 ) then passes through the intake wand ( 118 ) into and through the cooking oil extraction conduit ( 110 ), into and through the pump inlet conduit ( 108 ), into and through the pump inlet ( 166 ), into and through the pump ( 106 ) into and through the pump outlet ( 168 ), into and through the pump outlet conduit ( 112 ), into and through the cooking oil tank fill conduit ( 114 ), into and through the cooking oil tank fill port ( 116 ), and into the tank ( 102 ) as is seen in  FIG. 20 . 
     As previously shown, a cooking oil filtration device may be disposed between the cooking oil ( 101 ) in fryer vat ( 202 ) and the cooking oil ( 101 ) in the tank ( 102 ) so that potentially deleterious particulate matter is removed from cooking oil ( 101 ) and thusly prevented from entering the tank ( 102 ), in example between the cooking oil ( 101 ) and the intake wand inlet ( 122 ) as seen if  FIG. 1 ,  FIG. 7A , and  FIG. 7B . 
     In the above-described exploitation of the device ( 100 ), after all possible cooking oil ( 101 ) has been removed from the fryer vat ( 202 ), there will remain a residue ( 204 ) in the bottom of said vat ( 202 ) primarily comprising charred organic matter that flaked off food items previously prepared in the fryer vat ( 202 ), as seen in  FIG. 8A . Said residue ( 204 ) should be removed prior to recharging the fryer vat ( 202 ) with fresh cooking oil to prevent any number of undesirable effects well known in the art. To do so, implements in the accessory tray ( 170 ) may be used in manners known by one skilled in the art to remove said residue ( 204 ) and leave the fryer vat ( 202 ) in essentially pristine condition. Though particular items are depicted in  FIG. 17 , said depiction is not intended to limit the contents of said accessory tray ( 170 ). Other items deemed useful by one skilled in the art may comprise said accessory tray ( 170 ) contents. 
       FIG. 8  and  FIG. 8B  show a fryer ( 200 ) having a vat ( 202 ) comprising cooking oil ( 101 ). The intake wand is introduced into the vat ( 202 ) so that the intake wand inlet ( 122 ) is below the surface of the cooking oil ( 101 ) whereupon the cooking oil ( 101 ) is withdrawn as previously described. It will be understood that the intake wand ( 118 ) may be manually manipulated to place it in optimal operative orientation by grasping the handle ( 120 ). Also, the intake wand ( 118 ) may comprise a configuration to facilitate said positioning of the intake wand ( 118 ) in operative disposition, in example, but not limited to, the intake wand angle ( 186 ) seen in  FIG. 8B . 
     After cooking oil ( 101 ) is removed from the fryer ( 200 ), the pump ( 106 ) is disengaged, the intake wand may be returned to the wand holster, the cooking oil tank fill conduit ( 114 ) may be secured in storable orientation with the conduit brackets ( 158 ), the caster locks ( 138 ) may be disengaged, and the device ( 100 ) moved to its stowed location where the caster locks ( 138 ) may be re-engaged. 
     Known in the art are fat fryers ( 200 ) which have integral used cooking oil ( 101 ) removal means. There are those with drains which when opened, will allow used cooking oil to flow out by means of gravity into a collection vessel ( 210 ). There are those comprising pumps which will remove the used cooking oil from the fryer ( 200 ) and into conduits, in example, a fryer extraction hose ( 212 ) which will transfer the cooking oil ( 101 ) to a collection vessel. In such instances, the instant art need not comprise its own cooking oil removal means such as the previously recited embodiment comprising intake wand, pump, and appurtenant conduits. 
     Alternatively, as shown in  FIG. 6  and  FIG. 6A , the cooking oil inlet filter port cap ( 146 ) may be removed allowing cooking oil ( 101 ) to be introduced into the cooking oil port filter ( 148 ). Said introduction may be accomplished by pouring cooking oil ( 101 ) out of the vessel ( 210 ) into which it was previously drained or pumped and into said cooking oil port filter ( 148 ) as in  FIG. 6 . Said introduction may also be affected by directing the output from the fryer extraction hose ( 212 ) communicating with the aforementioned removal pump integral to the fryer ( 200 ) into the cooking oil port filter ( 148 ) as shown in  FIG. 6A . 
     It will be readily appreciated that once cooking oil ( 101 ) is deposited in the cooking oil port filter ( 148 ) said cooking oil will pass through the filter ( 148 ), in example by gravity, as in  FIG. 6  and  FIG. 6A , and into the cooking oil tank ( 102 ) where it is stored. 
     As previously recited, the cooking oil port filter ( 148 ) is removable from the cooking oil inlet filter port. This may be accomplished by grasping or hooking a finger or fingers under the cooking oil port filter flanges ( 154 ) and lifting out the cooking oil port filter ( 148 ). This allows for cleaning said filter ( 148 ) after usage whereupon it may be replaced by means of the same flanges ( 154 ). 
       FIG. 14A  and  FIG. 15  show that by means of fitting ( 156 ), the cooking oil tank fill conduit ( 114 ) may be disengaged from the pump outlet conduit ( 112 ). Also seen is that the tank ( 102 ) may comprise tank hooks ( 162 ) and that the pump housing ( 104 ) may comprise pump housing brackets ( 160 ). Additionally noted is that the pump housing brackets ( 160 ) and the tank hooks ( 162 ) are configured to communicate so that the pump housing ( 104 ) and the tank ( 102 ) may be removably attached. Therefore, one skilled in the art will understand that the pump housing ( 104 ) comprising the pump ( 106 ) may be removed from the tank ( 102 ) allowing the instant art ( 100 ) to be exploited in an embodiment not having a pump. Likewise, by reversing the above procedures, the pump housing ( 104 ) comprising a pump ( 105 ) and the cooking oil tank fill conduit ( 114 ) may be reattached to the tank ( 102 ) in operative disposition. 
     Further shown by  FIGS. 14A and 15  is that for convenience and/or ease of manipulation, the cooking oil extraction conduit ( 110 ) may be disengaged from the pump inlet conduit ( 108 ) so that the pump housing ( 104 ) and the cooking oil extraction conduit ( 110 ) and communicating elements may be handled separately. Additionally understood is that the manipulation of the pump housing ( 104 ) may be facilitated by use of the handle ( 105 ). 
       FIG. 14  shows that the pump inlet ( 166 ) may extend from the pump ( 106 ) to a pump inlet end ( 196 ) disposed outside the pump housing ( 104 ) where it may communicate with fitting ( 156 ) therefore the pump inlet conduit ( 108 ) may be eliminated. Also shown is that the pump outlet ( 168 ) may extend from the pump ( 106 ) to a pump outlet end ( 198 ) disposed outside the pump housing ( 104 ) where it may communicate with fitting ( 156 ) therefore the pump outlet conduit ( 112 ) may be eliminated. 
       FIG. 16  shows that the instant art ( 100 ) may comprise a tank evacuation cannula ( 254 ) having a cannula intake ( 256 ) extending from the cooking oil withdrawal port ( 140 ) toward the cooking oil tank floor ( 111 ) a distance sufficient to allow extraction of maximum quantity of cooking oil through said intake ( 256 ). Also noted is that a tank evacuation conduit ( 248 ) may be removably attached to the cooking oil withdrawal port ( 140 ) and/or the tank evacuation cannula ( 254 ) by fitting ( 156 ). Also seen is that the cannula intake ( 256 ) may comprise a configuration to facilitate optimum cooking oil ( 101 ) intake, in example, the oblique disposition of said cannula intake ( 256 ) to the tank floor ( 111 ). 
       FIG. 16A  shows that the cooking oil withdrawal port ( 140 ) may allow insertion therethrough of the tank evacuation conduit ( 248 ) having an intake ( 249 ) to a distance sufficiently proximal the tank floor ( 111 ) to allow withdrawal of the maximum volume of cooking oil ( 101 ). Also seen is that the tank evacuation conduit intake ( 249 ) may comprise a configuration to facilitate optimum cooking oil ( 101 ) intake, in example the oblique disposition of said tank evacuation conduit intake ( 249 ) to the tank floor ( 111 ). 
       FIG. 16  shows that the clip stick ( 130 ) may comprise graduations ( 131 ) to facilitate cooking oil ( 101 ) level and/or volume within the tank ( 102 ). 
       FIG. 16  shows that baffles ( 250 ) may be disposed, in example extending from the tank top ( 103 ) as shown in  FIG. 16 ), proximal the cooking oil port filter ( 148 ) to prevent contact with said filter ( 148 ) by cooking oil ( 101 ) in the tank ( 102 ) that may be agitated and/or caused to comprise waves by movement of the tank ( 102 ). 
     Now, one skilled in the art will readily appreciate that the tank evacuation conduit ( 248 ) may communicate with a means to affect passage of cooking oil ( 101 ) therethrough, in example a pump, and may further communicate with a storage and/or transfer means, in example a tank truck, said devices not integral to or permanently contiguous with any institution comprising fat fryers. Therefore, the instant device ( 100 ) need not have means of withdrawing cooking oil from the tank ( 102 ). 
       FIG. 16A  shows that the tank ( 102 ) may comprise a tank access maintenance port ( 252 ) to allow cleaning of the tank interior or maintenance or replacement of items located within said tank. 
       FIG. 9 ,  FIG. 9A ,  FIG. 9B , and  FIG. 9C  show an essentially prismatic cooking oil port filter frame ( 214 ) having substantially planar strips ( 226 ) which comprise cross members ( 222 ) and essentially upright members ( 224 ) which communicate at corners ( 230 ). The cooking oil port filter frame ( 214 ) comprises ends ( 234 ) having filter apertures ( 228 ), sides ( 232 ) having filter apertures ( 228 ), a bottom ( 236 ) having a filter aperture ( 228 ). Opposite the cooking oil port filter frame bottom ( 236 ) is a cooking oil port filter frame top ( 238 ) having an aperture ( 239 ). Also seen are cooking oil port filter frame brackets ( 218 ) extending essentially normal to the strips ( 226 ) and having elements essentially parallel to said strips ( 226 ). Also seen is that a cooking oil port filter frame end ( 238 ) comprises a slot ( 220 ). 
       FIG. 10  shows a filter bottom panel ( 240 ) having a sieve portion ( 246 ). Now it will be understood that the filter bottom panel ( 240 ) may be inserted through the cooking oil port filter frame slot ( 220 ) to the extent that it abuts the cross member ( 222 ) comprising the strip ( 226 ) as shown in  FIG. 11 . Also noted is that the filter panel sieve portion ( 246 ) is essentially equal in area to filter aperture ( 228 ) and occludes said aperture ( 228 ). 
       FIG. 10A  shows a filter end panel ( 244 ) having a sieve portion ( 246 ). Also seen is the cooking oil port filter frame end ( 234 ) with the filter bottom panel ( 240 ) inserted to maximum extent through cooking oil port filter frame slot ( 220 ). 
       FIG. 11  shows that the filter end panel ( 244 ) may be inserted through cooking oil port filter frame brackets ( 218 ) where it abuts the filter bottom panel ( 240 ). Also noted is that the filter panel sieve portion ( 246 ) is essentially equal in area to filter aperture ( 228 ) and occludes said aperture ( 228 ). 
       FIG. 12  shows a filter side panel ( 242 ) having a sieve portion ( 246 ) and a cooking oil port filter frame side ( 232 ) having brackets ( 218 ) and a filter aperture ( 228 ). 
       FIG. 13  shows that the filter side panel ( 242 ) may be inserted through brackets ( 218 ) and that the area of the sieve portion ( 246 ) and the area of the aperture  228 ) are substantially equal and that said sieve portion ( 246 ) occludes the aperture ( 228 ). 
       FIG. 13A  and  FIG. 13B  show the filter bottom panel ( 240 ) inserted through the cooking oil port filter frame slot ( 220 ) to maximum extent as previously described. Also shown are the filter side panels ( 242 ) inserted through brackets ( 218 ) and thusly fixed essentially against the cooking oil port filter frame sides ( 232 ). Additionally shown are the filter end panels ( 244 ) inserted through brackets ( 218 ) and thusly fixed essentially against the cooking oil port filter frame ends ( 234 ). 
       FIG. 13  and  FIG. 1313  also show the cooking oil port filter flanges ( 154 ) as previously described. 
     Now, one skilled in the art will readily appreciate that the cooking oil port filter frame ( 214 ) as previously recited in combination with the filter bottom panel ( 240 ), the filter side panels ( 242 ), and the filter end panels ( 244 ) may function after the fashion of the previously taught cooking oil port filter ( 148 ).
