Abstract
The glass beveling machine has a table for supporting a piece of glass to be beveled, and glass bevel grinding and polishing means in the form of wheels which may have individual driving heads mounted for adjustment relative to the table for selective angle and depth of bevel. Relative movement of the grinding and polishing means and the table in a glass beveling operation is preferably effected by reciprocating the table. For holding the glass piece in place on the table during the beveling operation retaining curb means and a vacuum plenum are carried by the table. Coolant and polishing solution drain-off is facilitated by tilted mounting of the table toward collection trough means.
Claims17
A glass beveling machine, comprising
- bevel grinding and polishing means;
- a table for supporting a glass plate to be beveled in generally face-up position and with an edge of the plate oriented for operation of said grinding and polishing means on said edge;
- means enabling relative movement of the grinding and polishing means and the table in a beveling pass comprising table guiding structure and means for reciprocatingly driving the table along said guiding structure;
- said table comprising an array of supporting bars in a slat-like spaced relation;
- limited contact glass plate supporting button-like members in spaced relation on said bars;
- and means located along an edge of the table nearest said bevel grinding and polishing means for holding the glass plate on the table against displacement during the beveling pass.

A glass beveling machine, comprising:
- bevel grinding and polishing means;
- a table for supporting a glass plate to be beveled in generally face-up position and with an edge of the plate oriented for operation of said grinding and polishing means on said edge;
- means enabling relative movement of the grinding and polishing means and the table in a beveling pass;
- means for holding the glass plate on the table against displacement during the beveling pass;
- said grinding and polishing means comprising respective wheels;
- shafts carrying said wheels rotatably;
- independent means for driving each of said shafts rotatably;
- respective separate carriages carrying said shafts and said driving means independently;
- rocker structure to which the carriages are attached;
- means supporting said rocker structure;
- means for adjusting the carriages in a generally up and down relation relative to said rocker structure;
- means for adjusting the rocker structure tiltably relative to said rocker structure supporting means;
- means for adjusting the position of said rocker structure supporting means in a generally horizontal direction toward and away from said table and said plate edge;
- said table sloping toward said grinding and polishing wheels;
- a vacuum plenum on the table adjacent to its lower edge and having a perforated surface supporting the lower edge portion of the glass plate in position for grinding and polishing by said wheels;
- and gauging curb means along said plenum projecting to a height above said plenum surface less than the thickness of the glass plate for gauging the position of the plate along the edge of the table for grinding and polishing of a bevel by means of said wheels.
13 more elements
A glass beveling machine, comprising:
- an elongate supporting frame;
- a table shorter than said frame and adapted for supporting a glass plate to be beveled in generally face-up position for grinding and polishing of a bevel on an edge of the glass plate;
- a pair of parallel spaced coextensive slide track rods extending throughout substantially the length of said frame;
- means on top of said frame supporting said track rods in an oblique plane sloping toward one longitudinal edge of the frame;
- slide bearings at each opposite end of said table slidably engaging said track rods and supporting said table in said sloping relation toward said one edge of the frame;
- means for reciprocatingly driving the table longitudinally of the frame along said track rods;
- a vacuum plenum mounted on the lower portion of the table with an edge of the plenum along the lower edge of the table, the plenum having an array of perforations spaced about two inches on center in an upper supporting surface on which a glass plate to be beveled is placed with its edge to be beveled at the lower edge of the table for bevel grinding and polishing by means located along said longitudinal edge of the frame toward which the table slopes;
- and a vacuum source separate from said table and plenum for effecting vacuum in said plenum to provide glass plate retaining suction through the perforations in said upper supporting surface and having a flexible conduit connection with said plenum to permit free reciprocating movement of the table relative to the vacuum source.
