     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 8 thereof, a new and improved lottery card scraper apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the lottery card scraper apparatus 10 of the instant invention essentially comprises a housing 11 having a top wall 12 spaced from a bottom wall 13, a first side wall 14 spaced from a second side wall 15, and a first end wall 16 spaced from a second end wall 17 defining a housing cavity 20 therewithin (see FIG. 3 for example). The first side wall 14 includes an entrance slot 18 positioned in adjacency to the bottom wall 13, and more specifically in communication with the cavity 20 and aligned with the housing floor 21 (see FIG. 4), with the second side wall 15 having an exit slot 19 coextensive with the entrance slot 18 in a parallel relationship, also in communication with and in contiguous orientation to the floor 21. A plurality of dove tail recesses 22 are integral with the first end wall 16 and extend to a recess floor 23, such that the dove tail plate 24 is received between the dove tail recesses 22 for abutment onto the recess floor 23. The dove tail plate 24 mounts a debris container 27 thereon, with the dove tail plate 24 having a plate opening 25 directed therethrough. The housing first end wall 16 is formed with a first end wall opening 16a arranged for alignment with the plate opening 25. A drive motor 28 is fixedly mounted within the housing cavity 20 spaced above the floor 21, as indicated in FIG. 3, mounted to the second end wall 17. The drive motor 28 is formed with an output shaft 29 having an output shaft pulley 30. A resilient cylinder 31 is arranged for spaced coaxial alignment with a rigid helical blade 35, having a central pulley 33 mounted therebetween also coaxially aligned relative to the resilient cylinder 31 and the rigid helical blade 35, with the components 31, 33, and 35 fixedly mounted about an axle 32 that extends from the first end wall 16 to the second end wall 17. A resilient drive belt 34 is mounted between the output shaft pulley 30 and the central pulley 33. In this manner, a lottery card (not shown) directed into the entrance slot 18 is pulled through the cavity 20 to the exit slot 19 by the resilient cylinder 31, while the helical blade 35 scrapes the card that is oriented between the helical blade 35 and the floor 21. Further, a lottery card may be put in endwise to avoid the resilient cylinder 30 and merely orient a portion to be scraped between the blade 35 and the floor 21. 
     The FIGS. 5 and 6 indicates the further use of an adjuster plate 39 arranged for mounting coextensively of the floor 21 arranged for lifting a lottery card and closing a gap between the adjuster plate 39 and the rigid helical blade 35. The adjuster plate includes a plurality of threaded rods 40 fixedly and orthogonally mounted to the adjuster plate 39, with each of the threaded rods 40 extending through the floor, as well as the bottom wall 13 and projecting below the bottom wall 13, with each of the threaded rods received within the adjusting tube 41 that is rotatably mounted into the bottom wall 13. Each adjusting tube 41 includes an adjusting tube internally threaded web 42 threadedly receiving the respective threaded rod 40 therethrough, such that rotation of the adjusting tube 41 that is captured between a lock flange 44 and the bottom wall 13 prevents axial displacement of each respective adjusting tube 41 relative to the bottom wall 13. Further, a rod flange 45 mounted to the rod at a distal end thereof spaced from the adjuster plate 39 captures a spring 46 between the rod flange and the adjusting tube web 42. In this manner, rotation of the adjusting tubes 41 permits reciprocation of the adjuster plate relative to the floor 21. 
     The FIGS. 7 and 8 indicates the use of a plurality of rotary dials 36 projecting through a modified top wall 12a, such that each rotary dial 36 fixedly mounts a dial cylinder 37 therein for viewing through a respective window of the top wall 12a. Each of the dial cylinders 37 includes an annular numerical array thereon for providing for an individual to count the number of lottery cards to be directed through the apparatus 10. 
     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.
