Abstract An apparatus for beveling a marginal edge of a sheet of glass which includes a table having a top opening in which a support plate for the glass sheet to be bevelled is disposed with a grinding wheel mounted on the table over the support plate, the grinding wheel being fixed to a shaft drivably connected by a belt to a drive motor on the table and the shaft being rotatably mounted in bearings supported on an adjustment device mounted on the table by means of which the horizontal, vertical and angular positions of the shaft and therefore the grinding wheel may be set together with a guide on a support plate which the marginal edge of the glass sheet to be bevelled engages as the glass sheet is moved slidably on the support plate with the glass sheet marginal edge in grinding engagement with the peripheral edge of the grinding wheel. ## Claims ### Claim 1 An apparatus for manually beveling a sheet of glass comprising, in combination, a frame, a grinding wheel, means for supporting said grinding wheel on said frame for axial rotation, drive means on said frame for rotating said grinding wheel said drive means including a motor means remotely spaced from said grinding wheel and connected thereto by belt means, a substantially planar support plate disposed on said frame in underlying relationship with a peripheral edge of said grinding wheel for slidably supporting a sheet of glass to be beveled, means for adjusting the axial position of said grinding wheel relative to said support plate, a guide member on the upper surface of said support plate for guiding engagement with a marginal edge of said sheet of glass during sliding movement of said sheet of glass on said support plate with said grinding wheel peripheral edge in grinding engagement with the marginal edge of said glass sheet to thereby provide a beveled marginal edge on said glass sheet during said sliding movement. wherein said support plate comprises a substantially rectangular grid member of rigid material and a cover member of elastomeric material disposed on the upper surface of said grid member and wherein said guide member is substantially disc shaped having a peripheral edge adapted to engage the edge of the glass sheet to be beveled. ### Claim 2 (depends on 1) An apparatus in accordance with claim 1 wherein said means for supporting said grinding wheel comprises a shaft drivably connected to said drive means, through said belt means and means for rotatably supporting said shaft on said adjusting means to permit the horizontal, vertical and angular positions of said shaft with said grinding wheel thereto be adjusted. ### Claim 3 (depends on 2) An apparatus in accordance with claim 2 wherein said adjustable means includes an upstanding support bracket on said frame, a support disc, slide means for mounting said support disc on said bracket for positioning said support disc in a selected vertical and horizontal position on said support bracket, means for adjusting the rotary position of said support disc and means for supporting said shaft on said support disc for adjusting the angular position of said shaft in accordance with the desired degree of bevel on said sheet of glass. ### Claim 4 (depends on 3) An apparatus in accordance with claim 3 wherein said drive means further includes a pulley assembly for drivably connecting said motor means to said shaft through said belt means for rotating said shaft with said grinding wheel thereon in a selected hoorizontal, vertical and angular position of said shaft. ### Claim 5 (depends on 4) An apparatus in accordance with claim 4 wherein said slide means comprises a vertically extending channel member on said support bracket, a vertically extending slide member slidably disposed in said vertically extended channel member, a horizontally extending channel in said vertically extending slide member, a horizontally extending slide member slidably disposed in said horizontally extending channel and means for clamping said horizontally and vertically extending slide members in said respective channels for adjusting the horizontal and vertical positions on said shaft with said grinding wheel thereon. ### Claim 6 (depends on 5) An apparatus in accordance with claim 5 wherein said means for supporting said shaft on said support disc includes a support plate mounted on said support disc, a pair of laterally spaced bearings on said support plate for rotatably supporting said shaft and means for clamping said support disc in a selected rotary position on said horizontally extending slide member to adjust the angular position of said shaft. ### Claim 7 (depends on 6) An apparatus in accordance with claim 6 including a shroud disposed in surrounding, spaced-apart relationship with a major portion of said grinding wheel peripheral edge and means for introducing a cooling fluid into the interior of said shroud in heat transfer relationship with said grinding wheel peripheral edge. ### Claim 8 (depends on 7) An apparatus in accordance with claim 7 wherein said frame comprises a table having upper, side and end frame members defining an opening and means for supporting said support plate within said opening in said underlying relationship with said grinding wheel peripheral edge to permit said cooling fluid and glass particles formed during the grinding of said glass sheet marginal edge to fall downwardly through said opening. ### Claim 9 (depends on 8) An apparatus in accordance with claim 8 including a pan supported on said table below said opening for collecting said cooling fluid and said glass particles and means connected to said pan for conducting said cooling fluid and said glass particles to a remote location.
