     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 8 thereof, a new electrostatic generator apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the electrostatic generator apparatus 10 of the instant invention comprises a housing 11 having a rigid polymeric construction, such as formed from the trademarked product &#34;PLEXIGLASS&#34; or the like. As best illustrated in FIGS. 1-3, the housing includes a housing top wall 14 with a crank formed of a crank handle plate 15 rotatably mounted about a handle axle 16 directed orthogonally through the housing top wall 14. A handle shaft 17 is rotatably mounted to the crank handle plate 15 and arranged spaced from and parallel to the handle axle 16. To complete the housing 11, the housing is provided with an unlabeled sidewall and a housing first floor 18 spaced from the housing top wall 14 a first spacing distance therefrom, with a housing second floor 19 spaced from the housing top wall a second spacing distance which is less than the first spacing. A beveled floor interface 20 connects the first floor 18 to the second floor 19. A flexible insulative polymeric hose 12 is mounted to the side wall of the housing and extends therefrom. The hose 12 includes a hose head 13 mounted to a distal end of the hose spaced from the housing 11. Suction cup feet 35 extend from the floor below the housing to secure and maintain the housing structure in a desired orientation relative to an underlying support surface. 
     Referring to FIG. 4 with concurrent reference to the figures previously discussed, it can be shown that a wiper plate electrode 21, typically formed of ceramic material or other such suitable material capable of generating static electricity relative to the floor structure, is rotatably mounted to a pivot plate 23 about a wiper plate support shaft 22, with a support shaft spring 24 interposed between the pivot the wiper plate electrode 21 to bias the wiper plate electrode in a spaced orientation relative to the pivot plate 23. During operation, the wiper plate electrode 21 is directed from a first position overlying the first floor 18 to a second position in engagement with the second floor 19 to generate static electricity by rubbing of the wiper plate electrode over the second floor. 
     As shown in FIG. 2, a pivot plate return spring 25 is directed from the pivot plate 23 within a side wall structure of the housing 12 to bias the wiper plate electrode 21 to the first position over the first floor 18. The pivot plate 23 is mounted about a pivot plate axle 27 extending orthogonally through the housing top wall 14, as indicated in FIG. 4 for example. The pivot plate 23 further includes a pivot plate slot 26 receiving a guide rod 34 therethrough that effects the oscillation of the pivot plate over the second floor from the first floor. 
     To direct this oscillation, a driven gear 28 is mounted about a driven gear axle 33 that is directed through the top wall 14 parallel to the pivot plate axle 27 and parallel the handle axle 16. The driven gear 28 is provided with driven gear teeth 29 arranged continuously about the periphery of the driven gear, with the guide rod 34 being fixedly and orthogonally mounted to the driven gear 28 but parallel and offset relative to the driven gear axle 33. A drive gear 30 is fixedly mounted to the handle axle 16 within the housing, having drive gear teeth 31 that are discontinuous defining a gap 32 of an arcuate length at least equal to or preferably greater than a plurality of the drive gear teeth 31. The gap 32 is operable to permit disengagement of the driven gear 28 relative to the drive gear and allow a return of the pivot plate 23 to the first position, as illustrated in FIG. 2 in solid line, over the first floor relative to a second position of the pivot plate positioned in engagement with the second floor 19, as illustrated in phantom in FIG. 2. Such oscillations across the floors 18, 19 generate a voltage potential or static electricity through the known process of triboelectric charging. 
     A conductor cable 36 is directed to the wiper plate electrode 21 through the pivot plate 23 and extends to resilient, extensible conductor wires 37 directed through the hose 12, in a manner as indicated in FIG. 5. The extensible wires 37 continue to the hose head 13, wherein a metallic core 40 is coaxially aligned therewith and movably mounted therewithin. The metallic core 40 includes a helical groove 39 cooperative with a groove projection 39a extending within the hose head 13. A core handle 41 fixedly mounted to the metallic core 40 extends through a helical slot 38 within the hose head 13, such that a pivoting of the core handle 41 effects displacement of the metallic core 40 within the hose head 13. A conductor core rod 42 is fixedly and coaxially mounted to the metallic core 40 and arranged to project within a head aperture 43 within a forward most distal end of the hose head 13, with the head aperture terminating in a head aperture wall 43a which precludes an introduction of objects within the head aperture. In this manner, a spacing &#34;S&#34; provides for a sufficient build-up of static electricity through the resilient conductor wires 37 which may be utilized to attract objects while simultaneously precluding contact with the object which would result in a release of the electric charge. The adjustable capability provided to the metallic core 40 and its associated conductor core rod 42 allows the spacing &#34;S&#34; to be adjusted to accommodate various objects. Note further, the vent 42a is provided to help relieve any air pressure differences generated as a result of the movement of the metallic core 40 within the hose head 13. 
     Further, to prevent excessive build-up of static electricity within the housing 11 reference is made to FIG. 3, wherein a first electrode 45 fixedly mounted to the second floor 19 includes a first electrode discharge leg 46 extending in electric communication with the first electrode 45 exteriorly of the housing to engage an underlying support surface, as the discharge leg 46 extends from the second floor below the housing. A second electrode 47 mounted to a second electrode shaft 48 includes a screw adjuster 49 threadedly directed through the second floor 19 in engagement with the second electrode shaft 48 to effect spaced adjustment of the first electrode 45 relative to the second electrode 47 by displacement of the screw adjuster 49 in its engagement with the second electrode shaft 48. 
     With reference to FIG. 9, it can be shown that the housing 11 may include a storage compartment 50 wherein an extended first floor 52 is spaced from the second floor 19 to define the storage space 50 whereby static electricity is stored within the space. The space 50 communicates with the second electrode shaft 48 by a small unlabeled wire which projects through the second floor 19, and insulators are provided to insulate both the screw adjuster 49 and the first electrode 45. The storage space 50 provides for greater storage of static electricity, thereby resulting in increased holding strength and longer holding durations of the attracted objects. A vent means 54 is provided for selectively venting air and/or static electricity from the storage space 50 as desired. 
     Alternatively, in lieu of rotation of the crank, a drive motor 50 may be provided, as illustrated in FIGS. 7 and 8, having a drive motor pulley 53 with an output belt 51 extending from the drive motor pulley 53 to a handle axle pulley 52 fixedly mounted to the handle axle 16. The drive motor may of course be of AC or DC configuration or may be switched to provide AC or DC usage as required. 
     Further, it should be noted that the wiper plate electrode 21 may in fact be provided with various metallic inserts and the pad itself may be formed of any suitable material permitting static charge development. The housing itself is typically formed of a non-conductive material providing for electrically insulating the charge within the housing structure. To this end, the gearing as well as all other materials may be configured to prevent charge leakage through the housing, as required, but if the housing should be electrically conductive, it should be understood that insulative materials would be employed to prevent leakage of charge from within the housing exteriorly of the housing, with the exception of the utilization of the static discharge structures 45 and 47 described above and the use of the hose structure 12. 
     As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will 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 as defined only by the claims annexed hereto.
