HOW PLATE GLASS IS BEvELED.
Process Requires the Greatest skill

Beveled glass is not new, but it is now
far more extensively used than formerly.
Twenty years ago beveled mirrors were
comparatively rare; now they are COM
mon and are seen in many shapes and
sizes. Beveled plates, large and small,
and both straight and bent, are used for
various other purposes. The process Of
glass beveling is very simple, but the work
calls for skill on the part of the operators.
The plate to be beveled goes first to the
roughing mill, which is a solid, heavy
steel wheel about two feet and a half in
diameter, set horizontally and turning at
a high rate of speed. The upper face, or
top, of this wheel is slightly roughened.
Suspended over the wheel is a big hopper
containing sand, which is fed down
through a spout in such quantity as may
be required upon the top of the rough,
faced steel wheel. The grinder holds the
plate to be ground In his hands, with the
edge to be ground off upon the face of the
roughing mill; he shifts the plate along az
the glass is ground away. The expert
grinder holding a sheet of glass against
the roughing wheel in this manner will
grind a true bevel, with perfectly
straight line along its inner edge, and he
brings the side bevels together with per-
fectly true angle at the corners.
In the roughing mill the bevel is wrought
to shape. but its face is rough looking ami
feeling, in fact, like what it is, ground
glass. The plate goes then to the emery
wheel, also Of steel and set HORIZONTALLY
Suspended over this wheel is a little hop
per filled with emery, the emery feeding
down upon the wheel Upon this wheel
the rough face of the bevel as 1t comes
from the roughing mill is again ground
the plate being held in the same manner
by a grinder, and the surface is brought
nearer 10 smoothness.
From the emery wheel the plate goes 10

turn horizontally. The smoothing stone
which is of an extremely fine sandstone.
is made with its upper surface, that
against which the glass is brought, very
slightly convex. This stone is finished rer-
fec fy smooth and It is so fine grained that
to the touch it seems almost to be polish-
ed. A tiny stream of water enough 10
keep The face of the stone wet, S made to
triclle down upon il, and the glass is
held to this wheel just as it was to the
others, and here the beveled edge is
brought down to a smooth surface but
not polished. The plate goss then to a
polishing wheel made of wood and set TO
turn vertically; the bevel edge of the
glass is held against the edge or face OF
this wooden wheel as 1t rapidly revolves.
The face of the wheel is kept wet and
constantly supplied with pu'verized stone.
Upon this wheel the Leveled edge gets its
first polish. The glass then takes the final
step in the tevelng process. It goes TO
another wheel. also of wood. and also
turning vertically, whose face is Of fell.
The face Of his wheel also is kept wet ard
ii is supplied with a fine polishing mater

at the first polishing wheel he glass is
held with the bevel against the edge. or
face. of The wheel. on the rouge wheel the
beyel gets its final polish and finish and
