Having described my invention what I claim as new and desire to secure by Letters Patent is:
1. A holder for a sheet of sand paper, comprising a support having a peripheral groove, a substantial half ring adapted to be snapped into the said groove for temporarily holding, the sheet in place, and means for clamping the sheet against the support and maintaining the half ring in place.
2. A holder for a sheet of sandpaper, comprising a cylindrical support, an annular groove in the periphery thereof, an enlarged disc-like portion below the said groove, a substantial half ring adapted to snap into the said groove for temporarily holding the sheet in place, and means for clamping the sandpaper against the enlarged disc portion and maintaining the ring in place.
3. A holder for a sheet of: abrasive material, comprising a cylindrical support, a pair of annular grooves in the periphery thereof, an enlarged disc-like portion below the said grooves and provided with an external thread, a pair of substantial half rings adapted to snap into the said grooves for holding the said sheet about the support, and a nut on the disc portion to clamp the bottom of the sheet against the top surface of the said disc portion and maintain the half rings in place.
at. A sandpaper holder comprising a disclike member provided with threads on its periphery, a reduced cylindrical portion extending from the said disc member and provided with an annular peripheral groove, a substantial half ring fitting into the said groove for maintaining the sandpaper about the periphery of reduced cylindrical portion, and a nut to clamp the sandpaper against one surface of the disc-like member.
5. A holder for a sheet of sandpaper, comprising a cylindrical hub provided with a central longitudinal bore and an annular groove in the periphery thereof, a resilient bufier in the said bore, the said hub and buffer forming a support for the sandpaper, an enlarged disc-like portion below the said annular groove, a substantial half ring fitting into the said groove for maintaining the sandpaper about the support, and a nut to clamp the lower edge of the sandpaper against the said disc-like portion.
In testimony whereof I have hereunto affixed my signature.
CARMELO ADORNETTO.
