Improvements in Mills and Apparatus for Bevelling Glass.
I WILLIAM OLIVER BAILEY of The Excelsior Works Wenlock Road City
Road in the County of London Glass Merchant Silverer and Beveller do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to improvements in vertical mills and apparatus for
bevelling plates or sheets of glass in combination with a vertical frame and has for
its especial objects to free the downward or upward stroke of the mill as the case
may be from the glass in course of being bevelled and to improve the method of
supplying the grinding or other material and so to enable the bevelling to be
effected more expeditiously and cheaply and with greater accuracy and ease than
if an ordinary grinding mill fed with grinding material from above in the ordinary
way were employed.
In order that my invention may be more fully understood I annex drawings of
my improved grinding mill and apparatus.
Figure 1 is a side elevation of the said mill and apparatus partly in section.
Figure 2 is a front elevation of the said mill partly in section.
A is the mill, B the hopper, C the shield, D the feeder, E the mill shaft, F the
driving chain to feeder, G the outlet from hopper, H the feeder shaft, I the
grinding material. The mill is constructed of the usual materials and actuated
in the usual way and is especially though not exclusively intended for use in
combination with a vertical travelling frame such as is described in my Letters
Patent No. 11,382 of 1894.
In order to carry out the purposes above described I construct the face of the
grinding mill with a bevelled edge as shewn in Fig. 1. When the mill is in
operation the edge of the glass to be bevelled is made to traverse the face of
the rim of the mill about its centre but instead of its being made to traverse the
face of the mill as heretofore the mill is so placed that its face makes an angle
with the plane of the transit of the travelling frame so that the edge of the glass is
made to traverse the bevelled surface of the mill on the upward stroke of the
mill only.
The sand or other grinding material is fed from the hopper B Fig. 1 to the
face of the mill by means of the worm screw D. Fig. 1 which is actuated by means
of the chain and shaft F and H so that the grinding medium is constantly and
regularly supplied to the mill a splash shield C being fixed to the hopper for the
purpose of preventing superfluous material from rising too high.
Although only the grinding mill has here been referred to I intend that a whole
set of mills such as are required for grinding smoothing and polishing shall be
constructed and operated as above described except that I may wish to make the
smoothing and polishing mills operate in the opposite direction to the grinding
mill and that I may or may not use the hopper and feeder above described in
connection with both or either of them.
Instead of being used in combination with a vertical frame as above described my
improved mill and apparatus may be used for the purpose of bevelling glass held
vertically without the employment of a frame.

page_text: Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is as follows:
1st. In mills for bevelling glass the use of a bevelled edge substantially as herein
described or shown.
2nd. In combination with such mills as aforesaid the use of feeding apparatus
substantially as herein described or shown.
