PROVISIONAL SPECIFICATION.
Improvements in the Mode of and Means for Bevelling Glass
Circles.
We, EDWARD HENRY PEARCE, Bridge Street, Broad Street, Birmingham,
Manufacturer, and EDWARD BROWN, 38 Birchfields, Birmingham, Compass Maker
both in the County of Warwick, do hereby declare the nature of our said invention
to be as follows:-
--
Our invention has for its object improvements in the mode of and means for
bevilling glass circles by which several of such circles may be bevilled at the same
time and with less attention from the operator than was required by the bevilling of
one as hitherto done.
In carrying our invention into effect we arrange a circular frame above the
horizontally revolving stone and upon this frame we fix two, three, four or more
sockets into each of which we place a bracket in such a manner that the pivot of
the said bracket can turn in its socket. Each bracket is provided with a revolving
spindle having a pulley upon it and this pulley is connected by a band with a pulley
on the central vertical shaft of the stone. Each bracket is also provided with two
bearing arms between which the spindle supporting the glass to be bevilled is
mounted so as to revolve, the inclination of the spindle being arranged to suit the
required bevil on the glass. The glass is kept to the stone by a coiled spring which
is provided between a shoulder on the spindle and the disc. The spindle supporting
the glass is geared with the pivotted spindle by toothed wheels and the glass is
attached to a disc on the spindle by means of cement or by vacuum as described in
Patent No. 8310 A.D. 1885. This arrangement allows the bevils of as many
glasses as the stone will accomodate to be ground or polished at the same time
without attention except for taking out or replacing the spindle in the clip arms of
the brackets.

We, EDWARD HENRY PEARCE, Bridge Street, Broad Street, Birmingham,
Manufacturer, and EDWARD BROWN, 38 Birchfields, Birmingham, Compass Maker,
both in the County of Warwick, do hereby declare the nature of our said invention
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:—
Our invention has for its object improvements in the mode of and means for
bevilling glass circles by which several of such circles may be bevilled at the same
time and with less attention from the operator than was required by the bevilling
of one as hitherto done.
In carrying our invention into effect we arrange a circular frame above the
horizontally revolving stone and upon this frame we fix two, three, four or more
sockets into each of which we place a bracket in such a manner that the point of

page_text: the said bracket can turn in its socket. Each bracket is provided with a revolving
spindle having a pulley upon it and this pulley is connected by bands and
pulleys with a pulley on the central vertical shaft of the stone. Each bracket is
also provided with two bearing arms between which the spindle supporting the
glass to be bevilled is mounted so as to revolve, the inclination of the spindle being
arranged to suit the required bevil on the glass. The glass is kept to the stone by
a coiled spring which is provided between a shoulder on the spindle and the disc.
The spindle supporting the glass is geared with the pivotted spindle by toothed
wheels and the glass is attached to a disc on the spindle by means of cement or by
vacuum as described in Patent No. 8310 A.D. 1885. This arrangement allows the
bevils of as many glasses as the stone will accomodate to be ground or polished at
the same time without attention except for taking out or replacing the spindle in
the clip arms of the brackets.
In order that my invention may be clearly understood and more easily carried
into practise we have appended hereunto a double sized sheet of drawings upon
which we have fully illustrated the nature of our said improvements and the mode of
carrying the same into effect.
Figure 1, is a plan of the stone showing apparatus for bevilling four circles
simultaneously.
Figure 2, is a perspective view of Figure 1 the apparatus for bevilling one circle
only, being shown for the convenience of illustration.
Figure 3, is a front elevation of the apparatus.
Figure 4, is a side elevation of the apparatus.
Our invention consists of one, two, three or more supporting brackets B attached
to the frame C which is fixed above and independant of the circular revolving
stone D. These brackets B are made to pivot upon the frame C so that they may
be set to any desired angle. The revolving spindle F which carries the pulley f
is mounted to revolve in the bracket B and is connected with the central vertical
revolving shaft H by means of the bands K, K', and intermediate pulleys e¹ and e²
which are mounted upon the spindle E which is in turn supported by the frame or
band e. The central vertical shaft H revolves with the stone D and the motion is
conveyed therefrom to the spindle F by the bands K and K. Each bracket B and
spindle F is provided with the arms and 62 in the forked ends 3 and 4 of which
the spindle M supporting the glass N to be bevilled is mounted so as to revolve by
means of wheels f¹ and m¹. The stone is grooved at d¹ to suit the diameter of the
glass and the glass is kept to the stone by the coiled spring m² which is provided
for the purpose.
The glass N is attached to the disc P or the spindle by means of
cement or by vacuum as described in Patent 8310 A.D. 1885. By our invention,
as many glasses as the stone will accomodate the apparatus for may be bevilled at
one time as shown by Figure 1 without any attention further than taking off and
replacing the glasses upon the disc P. The inclination of the bevil is regulated by
the pivot of the bracket and is secured in the required position by the nut and
pin but we may vary this arrangement as also the shape of the frame C and
bracket B and we may drive direct on to the spindles F or M from the central
shaft H without departing from the nature of our said invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The mode of and means for bevilling glass circles substantially as and for the
purpose herein set forth and shown upon the accompanying drawings.
