Abstract
A hand fed glass beveling apparatus comprises table means for slidably supporting a hand manipulated glass piece to be beveled under a grinding and polishing head including a spindle selectively carrying a grinding wheel or a polishing wheel and driven by a motor on a mount permitting adjustments for incremental variations in width of bevel. An edge gauging stop is carried by the table means under the head. Selectively, dual streams of coolant water or polishing solution are directed to the working surface of the wheel under a splash guard hood. The table means include spaced limited contact knobs which facilitate maneuvering the glass piece relative to the wheel.
Claims28
Hand fed glass beveling apparatus, comprising:
- upwardly facing table means for slidably supporting a hand manipulated substantially flat glass piece to be beveled;
- said table means having a substantial central solid flat glass-supporting area offset upwardly relative to a surrounding lower elevation area on which an array of spaced upwardly extending limited contact supporting projections have their upper ends in a common plane with said flat area to provide support for a glass piece which may project beyond the flat area during a beveling operation;
- a rotary spindle having means at one end for rotatively selectively supporting a bevel grinding or polishing wheel having a bevel-working surface;
- means for driving the spindle rotatably;
- means supporting the spindle and driving means in general alignment over said flat area of the table means with said wheel-supporting end adjacent to the flat area of the table means for positioning the supported wheel with its bevel-working surface oriented to work on an edge of the glass piece slidably manipulated on said flat area of the table means toward the working surface;
- and gauging stop means mounted on the table means contiguous to an edge of said flat area for stopping the glass piece edge relative to said working surface to assure proper predetermined bevel width on the glass piece being beveled.

Glass beveling apparatus including upwardly facing means for supporting a flat glass piece to be beveled, and grinding and polishing means operatively related to the supporting means, said supporting means comprising:
- a plurality of upwardly extending supporting knobs;
- means carrying said knobs in spaced relation to one another and with crown surfaces of the knobs in a common glass supporting plane;
- and means securing said knobs to said carrying means immovably and in fixed positions relative to said carrying means.
