Title: Sand paper disc loading device

Description:
BACKGROUND OF THE INVENTION 
     The invention relates to a sand paper disc loading device that allows sanding discs to be easily and accurately placed on a sander. 
     Several references show various tools and accessories. U.S. Pat. No. 6,050,887 to Chang discloses a sand cloth packaging system comprised of a plurality of guide posts, allowing for labor-saving replacement for a vacuum type rotary sander. U.S. Pat. No. 4,558,542 to Marton and U.S. Pat. No. 4,437,271 to McAvoy disclose various circular disc assemblies. 
     While these units may be suitable for the particular purpose employed, or for general use, they would not be as suitable for the purposes of the present invention as disclosed hereafter. 
     SUMMARY OF THE INVENTION 
     It is an object of the invention to produce a sand paper disc loading device that allows sanding discs to be easily and accurately placed on a sander including a sand paper support adapted for holding a plurality of sanding discs. The sand paper support has a front surface and a back surface. The front surface has a plurality of dowels extending outwardly therefrom in a spaced relationship. The dowels are arranged to correspond with dust collection apertures of the sanding discs. The back surface has a handle extending outwardly therefrom. A support stand is adapted for removably coupling with the sand paper support. The support stand includes a base member positionable on a flat recipient surface. The support stand includes a support plate hingedly coupled with the base member. The support plate includes support means for locking the support plate in an angular orientation with respect to the base member. The support plate includes a recess extending inwardly of an upper edge thereof. The recess is dimensioned for receiving the handle of the sand paper support therein for supporting the sand paper support on the support plate. 
    
    
     To the accomplishment of the above and related objects the invention may be embodied in the form illustrated in the accompanying drawings. Attention is called to the fact, however, that the drawings are illustrative only. Variations are contemplated as being part of the invention, limited only by the scope of the claims.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     It will be noted in the various figures that the device relates to a sand paper disc loading device that allows sanding discs to be easily and accurately placed on a sander. In its broadest context, the device consists of a sand paper support and a support stand. Such components are individually configured and correlated with respect to each other so as to attain the desired objective. 
     The sand paper support  12  is adapted for holding a plurality of sanding discs  14 . The sand paper support  12  has a front surface  16  and a back surface  18 . The front surface  16  has a plurality of dowels  20  extending outwardly therefrom in a spaced relationship. The dowels  20  are arranged to correspond with dust collection apertures  22  of the sanding discs  14 . The back surface  18  has a handle  24  extending outwardly therefrom. In use, the sanding discs  14  will be placed with their abrasive surface against, or facing the front surface  16  of the sand paper support  12 . When an initial, or new disc  14  is needed, the dowels  20  are aligned with the vacuum apertures of the sander so that the disc  14  can be properly positioned on the sander with the dust collection apertures  22  aligned with the vacuum apertures. This will insure proper operation of the sander and its dust collecting capabilities. It should be noted that the shape and size of the sand paper support  12  will correspond with the specific type of sander. 
     The support stand  26  is adapted for removably coupling with the sand paper support  12 . The support stand  26  includes a base member  28  positionable on a flat recipient surface. The support stand  26  includes a support plate  30  hingedly coupled with the base member  28 . The support plate  30  includes support means  32  for locking the support plate  30  in an angular orientation with respect to the base member  28 . The support plate  30  includes a recess  34  extending inwardly of an upper edge thereof. The recess  34  Rot is dimensioned for receiving the handle  24  of the sand paper support  12  therein for supporting the sand paper support  12  on the support plate  30 . In the preferred embodiment, the support means  32  includes a U-shaped bar  36  pivotally coupled with the support plate  30  and a notch  38  formed in the base member  28 . The U-shaped bar  36  can be positioned within the notch  38  to allow the support plate  30  to be supported in the angular orientation with respect to the base member  28  to properly hold the sand paper support  12  for use with a sander.
