Process by Which the Edge is Cut
Away and Refinished.

| From the New York SUM-
| Beveled glass is not rev, but it is now
| far more extensively used than formerly.
Twenty years ago beveled mirrors were
comparatively rare, now they are common,
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 bev-
cling is very simple, but the work calls for
skill on the part of the operators.
The plate to be beveled goes first to the
roushns mill, which is a solid, heavy steel
wheel about two feet and half in diane
ter, set horizontally, and turning at a high
rate of speed. The upper face or top of
this wheel, is slightly rough ned. Suspend
ed over the wheel is a big hopper contain
ing sand, which is fed down through a
spout in such quantity may be required
upon the top of the rough-faccd steel wheel
The grinder holds the plate TO be ground
in his hands, with the edge to he ground
Off 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 rOugning wheel IN this
manner, VIII grind a true bcvel, WITH a per
fecuy straight line along its inner edge
and he brings the side beveIs together with
perfectly true angle at the corners.
In the roughing mill the bevel IS wrought
to shape, but its face is rough-Iooking and
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 Ills wheel
the rough face of the beyel as it comes
from the roughing mill is again ground
the plate being held in the same manner
by 4 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 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 perfectly
smooth and it is so fine grained that 10 the
touch II seems almost to be polished. a
tiny stream of water. enough to keep the
face of the stone wet, is made TO trickle
down upon it 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 goes then to a polishing wheel made
of wood and set to turn vertically: the
bevel edge of the glass is held against the
edge face of this wooden wheel as it
rapidly revolves. The face % the wheel is
kept wet and constantly supplied With pull
verified stone. Upon this wheel the bev-
eled edge gets it first polish. The glass
then takes the final step in the beyeling
process. 1t goes to another wheel, also of
wood, and also turning vertically, whose
face is of felt The face Of this wheel
also is kept wet and ii is supplied with a
fine polishing material called from its color
rouge. Here, at the first polishing wheel
the glass is held with the bevel against the
edge, or face of the wheel. On The rouge
wheel the bevel gets its final polish and
finish and the surface of the beveled edge
which after the first operation was rough
like ground glass, is now as smooth and
as polished the fiat surface Of the plate
Great plates that are too big to be held
by hand are locked into frame that can
be moved to bring the edges to be
beveled against wheels adjusted for the
purpose.
