Edges of Glass.
I, JAMES CLYDE LOVE, of 29, Bentinck Street, Sandyford, in the County of the
City of Glasgow, Looking Glass Manufacturer, do hereby declare the nature of
my invention to be as follows:-
:-
This invention has reference to improvements in and relating to machinery for
bevelling the edges of glass.
According to my improvements the glass is mounted and securely clamped to an
accurately planed table padded with rubber or pneumatic seats, and this table is
adjustably set to any desired angle by screws, quadrants, or like appliances. The
frame carrying the table works over slide guides, and receives a reciprocating to
and fro motion, somewhat analogous to that of a slide rest or saddle along the bed
of an ordinary turning lathe, the travel being regulated by means of adjustable
dogs and belt guide. A secondary motion is also given to the table so as to obtain
an adjustably varied velocity of travel, and this may be obtained by crank con-
nections to a worm wheel and worm operated by the screw shaft which gives the
first motion to the table.
A series of grinding discs or stones such as four sets, are mounted at spaced dis-
tances apart on a turn table drum or drum pivotted on a horizontal table working
over a slide bed. This table receives a horizontal reciprocating motion at right
angles to that given to the table carrying the glass, and this motion may be given
by a connecting rod from an adjustable pin and slotted toothed wheel driven by
wheel gearing. Each of the grinding discs has a vertical spindle on which is
carried a bevel or toothed wheel and the turn table or drum is turned or rotated
round a part of a revolution to bring each of these wheels in sequence into gear
with a bevel or similar wheel mounted on a horizontal shaft carried in bearings on
the reciprocating table, but which receives a rotating motion from any prime
moving shaft so as to rotate the spindle carrying the disc for the time being in gear"
to perform the grinding or bevelling action, and the height of these dises is regu-
lated by means of a screw at the end of spindle.
This machine may be duplicated or multiplicated by adding one or more slide
frames with gear and glass holders thereby increasing efficiency.

Edges of Glass.
I, JAMES CLYDE LOVE, of 29, Bentinck Street, Sandyford, in the County of the
City of Glasgow, Looking Glass Manufacturer, do hereby declare the nature of
my invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement, that is to say:-
This invention has reference to improvements in and relating to machinery for
bevelling the edges of glass.
And in order that my said invention and the manner of carrying same into
practice may be properly understood, I have hereunto appended a sheet of ex-
planatory drawings in which the same reference letters are used to indicate corre-
sponding parts in the several figures where shown. Figure 1 is a side elevation,
and Figure 2 a view at right angles of my improved machine for bevelling the
edges of glass, and Figure 3 is a plan view corresponding to Figure 2, while
Figure 4 shows detached views of an alternative gear.
Referring to these drawings:-
-
According to my improvements the glass is mounted and securely clamped to an
accurately planed table A padded with rubber or pneumatic seats, and this table
is adjustably set to any desired angle by screw spindles A' and bevel wheels A²
gearing into wheels A³ on a horizontal spindle A carried on a frame A5 with screw
nut operated by a hand turned spindle A6; while the glass can be moved to or
from the turn table by pinions a mounted on a horizontal spindle a¹ and gearing
into a rack on under side of table A. The frame B carrying the table A is mounted
on wheels B¹ working between underhung cheek plates B2 and receives a recipro-
cating to and fro motion from the screw shaft C working through the screw nut C
carried on a bracket C2 suspended from frame B, the travel being regulated by
means of ordinary adjustable dogs and belt guide. Or instead of travelling on
wheels the frame may work over slide guides like the slide rest of an ordinary
lathe. A secondary motion is also given to the table B so as to obtain an adjustable
reciprocating travel, and this may be obtained by a right and left hand grooved
drum mounted on the screw shaft C which gives the first motion to the table;
or as shown in Figure 4 this may be obtained from a bevel wheel c¹ mounted
loosely on the shaft C and gearing into a bevel wheel which has a connecting
rod connected to a fork which gives an adjustable reciprocating motion to the
shaft C. The rotating motion would be given to the shaft C by belts from the
pulleys C*.
A series of grinding discs or stones D such as four sets, are mounted at spaced
distances apart on a turn table or drum D¹ pivotted at D2 on a horizontal table or
carriage D³ carried on wheels D. This table D' receives a horizontal reciprocating
motion at right angles to that given to the table A carrying the glass, and this
motion may be given by a connecting rod d from an adjustable pin d¹ and slotted
worm wheel driven by a worm on the shaft E. Each of the grinding discs D)
has a vertical spindle e carried in brackets e¹ and on which is carried a bevel or
toothed wheel e2 and the turn table or drum D¹ is turned or rotated round a part
of a revolution to bring each of these wheels e in sequence into gear with a bevel
or similar wheel e³ mounted on a horizontal shaft E carried in bearings D5 on the
reciprocating table D³, but which receives a rotating motion through pulleys E¹
from any prime moving shaft, so as to rotate the spindle e carrying the disc 1)
for the time being in gear to perform the grinding or bevelling action, and the
height of these discs is regulated by means of a screw e at the end of spindle e.

mounted on the radial arms f¹ are for giving an antifriction action
to the spindle of turn table D¹.
Instead of bevel wheels
tuted.
3 surface contact or friction wheels may be substi-
This machine may be duplicated as shown in Figures 2 and 3 or it may be
multiplicated by adding one or more slide frames with gear and glass holders
thereby increasing efficiency.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
First. In machinery for bevelling the edges of glass, the arrangement of glass
carrying frame or frames, having an adjustable reciprocating motion given to same,
substantially as set forth.
Second. In machinery for bevelling the edges of glass, the arrangement of turn
table and grinding discs with vertical spindles and wheel gearing, to enable the
glass to be ground and finished at each setting without removal from table, sub-
stantially as set forth.
Third. The arrangement in combination of the parts of a machine for bevelling
the edges of glass, substantially as herein described in reference to and shown in
the accompanying drawings.
