     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 6 thereof, a new and improved toaster cover door apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the toaster door cover apparatus 10 of the instant invention essentially comprises a toaster assembly 11 having a top wall 12, with bread slots 13 directed therethrough. Each of the bread slots are of a predetermined width and of a predetermined length. A door plate 14 is hingedly mounted about an associated hinge member 15 in adjacency relative to each bread slot 13, wherein each door plate 14 is at least of a predetermined width and the predetermined length. The toaster assembly 11 is constructed and arranged with conventional heating elements 16 spaced apart to define a bread receiving gap 17 below each associated bread slot 13 to cooperate in a conventional manner in association with a thermostat 18 to effect toasting of bread directed into each gap 17. An elevator plate 19 is reciprocatably mounted interiorly of the toaster in cooperation with the slots to permit lowering of bread into each associated gap 17. The elevator plate 19 cooperates with a side wall slot 20 and includes an elevator plate handle 21 mounted to the elevator plate 19 exteriorly of a side wall of the toaster assembly 11 to permit selective manual lowering of a bread component within an associated gap 17. Each door plate 14, as illustrated in FIG. 1 for example, includes a handle flange 14a orthogonally oriented relative to each door plate to permit ease of manual manipulation of each door plate. 
     The FIGS. 3 and 4 indicate the apparatus utilizing automatic door closing structure to include a door cable 22 having a first end mounted to a respective door plate 14, with a second end directed into the toaster through an associated cable receiving opening 24 through the top wall 12 mounted to an abutment pin 25. Upon lowering of the elevator plate 19, the abutment pins 25 are contacted effecting tensioning of an associated cable 22 that in turn is directed about a guide boss 22a over and aligned with a respective abutment pin guide slot 26 permitting downward displacement of the guide pins 25 and associated tensioning of the cables 22 to effect closure of a door over a respective slot 13. A spring hinge 23 normally biases the doors in an orthogonal orientation relative to an associated slot 13. 
     The FIGS. 5 and 6 indicate the structure further employing a cup member for melting of butter therewithin for spreading upon toast for convenience, formed with a heat tube 27 in communication within the toaster directed through the top wall 12. The heat tube 27 includes an insulative exterior liner 28 formed thereabout. A heat transmissive metallic floor 29 is mounted fixedly to an upper end of the heat tube 27 having a continuous side wall 30 formed of a non-heat transmissive polymeric material to avoid injury to an individual as is the purpose of the liner 28. The side wall 30 is formed with an upper edge 31 having a pair of support recesses 33 directed into the upper edge that are diametrically aligned relative to one another into the upper edge to support a brush handle 34. The brush handle 34 is formed with a head 35 having a matrix of bristles secured to the head to permit the spreading of butter and the like onto toast in use with the invention. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
