Beveled glass in not new, but it Is
now far more extensively used than
formerly. Twenty years ago beyeled
mirrors were comparatively rare, now
they are common, and are seen In many
shapes and sizes. Beveled plates, large
aud small, aud both straight and bent
are used for various other purposes.
The process of glass beyeling is very
simple, but the work calls for skill on
the part of the operators.
The plate to be beveled goes first TO
Ehe roughing mill, which is a solid
heavy steel wheel about two feet and a
half feet In diameter, set horizontally,
and turning at 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 II
spout In such quantity as may be requir-
ed upon the top Of the roughfaced
steel wheel The grinder holds the
plate to be ground in his hands, with
the edge to be ground of upon the face
of the roughing mill;,he shifts the plate
along as the glass is,ground away. The
expert grinder, holding a sheet of glass
against the roughing,wheel In this man
ner, will grind trueibeyel, with a per-
fectly straight line along its inner edge
and he brings the side bevels together
with d perfectly true angle at the cor
ners.

wrought to shape, but Its facets rough
looking and feeling. In fact, like what
1T Is, ground glass. The plate goes then
to the enemy wheel, also of steel and
set horizontally. Suspended over this
wheel Is little hopper filled with
emery. the emery feeding down upon
the wheel. Uponfthis wheel the rough
face of the bevelias 1t comes from the
ronghing mill Is again ground. the plate
being held In, the same manner by a
grinder, and the surface is brought
nearer to smoothness
From the emery wheel the)plate goes
TO the smoothing stone. which is also
set to turn horizontally. The smooth
ing stone, which is of,an extremely
fine sandstone is made iwlth,its upper
surface, that against which the, glass Is
brought, very slightly convex. This
stone is finished perfectly smooth and
it Is so fine grained that to the touch 1t
seems almost to be. polished. A tiny
stream of water. enough to keepA the
face OF the stone wet. is made ! TO
trickle down uponIit and the glass IS
held to this wheel, Gust as 1t was to the
others. and here the beveled edge is
brought down to a smooth surface. but
not polished. The plate goes then to
polishing wheel made of wood and, set
TO turn vertically; the 'bevel edge of,the
glass is held against the edge or faceof
this wooden wheel as It rapidly re-
wolves. The face OF the wheels kept wet
and constantly supplied with pulverlz-
ed stone. Upon this wheel the beveled
edge gets 1t first polish. The glass
then takes the finalstep In the beveling
process. 1t goes to,anotherfwheel,a also
of wood, and also turning vertically,
whose face is Of felt. The face OF this
wheel also is kept wetIand 1t is suppl
ed with a fine polishing meteriaI called
from its color. rouge. Here. as iat the
first polishing wheel. 1.-THE glass is held
with the bevelagainstithe edge, orlface
OF the wheel. On the 7rouge wheel the
bevel gets its final polish and finish tand
the surface of the bevGed edge which
after the first operations was rough like
ground glass is now asssmooth andEas
polished as the fat surface of the plate,
Great plates that are ltoo big to be
held by hand are locked into frame
that can be so moved as' TO bring the
edges to be beyeled against wheels adj
