PROVISIONAL SPECIFICATION.
Improvements in and relating to Grinding and Polishing Machines.
I CHARLES BOROMEO BERGEN of Church Bridge Glass Works Oldbury
Glasscutter do hereby declare the nature of my said invention to be as follows:-
My invention has for its object improvements in and relating to grinding &
polishing machines by which the material or matter used in the process is
automatically fed on to the grinding or polishing buffer or wheel brushes.
In carrying my invention into effect I mount an axle or spindle in suitable
bearings adjacent to the axle or spindle of the grinding or polishing machine upon
which the brush or buffer is mounted. Upon this independent axle an arm is formed
having at its extremity a brush or pad which rotates when the spindle is revolved
which revolving movement is effected by a pulley connected by a band or other
suitable gearing with any convenient part of the machine.
The pulley is geared down in speed so that as the brush or pad rotates it passes
over a platform or through a vessel containing the material required for the polishing
process and steadily conveys a portion of the said material to the revolving brush
buffer or bob which is thus smeared with it in the course of the rotating movement
of the brush against the said wheel brush buffer or bob.
Dated this 18th September 1894.

COMPLETE SPECIFICATION.
Improvements in and relating to Grinding and Polishing Machines.
I CHARLES BOROMEO BERGEN of The Church Bridge Cut Glass Works
Oldbury in the County of Worcestershire Manufacturer 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 has for its object improvements in and relating to grinding &
polishing machines by which the material or matter used in process is automatically
fed on to the grinding or polishing buffer or wheel brushes.
In carrying my invention into effect I mount an axle or spindle in suitable
bearings adjacent to the axle or spindle of the grinding or polishing machine upon
which the brush or buffer is mounted upon this independent axle an arm is formed
having at its extremity a brush or pad which rotates when the spindle is revolved
which revolving movement is effected by a pulley connected by a band or other
suitable gearing with any convenient part of the machine.
The pulley is geared down in speed so that as the brush or pad rotates it passes
over a platform or through an open vessel containing the material required for the
polishing process and steadily conveys a portion of the material to the revolving
brush or buffer or bob which is smeared with it in the course of the rotating movement
of the brush against the said wheel brush buffer or bob.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a sheet of drawings upon which I have fully
illustrated the nature of my said improvement.
Figure 1 is a sectional end elevation of a polishing lathe with my improved rotary
feed applied thereto.

page_text: Referring to the drawings I mount the spindle a¹ in suitable bearings B in a
convenient position preferably at the rear of the grinding or polishing machine C
upon which the brush or buffer D is mounted. Upon the axle or spindle a¹ I mount
the arm a² which carries at its extremity the brush or pad A which rotates with the
revolving of the spindle a'. For revolving the spindle a' the pulley E is provided
and is connected by the band F or other suitable gearing with any convenient part
of the machine; the pulley E is geared down in speed so that the rotation of the
brush or pad A causes it to pick up a sufficient quantity of the material required
for the polishing or grinding which is contained in the vessel H and steadily conveys
a portion of same to the revolving buffer brush or bob D thus smearing the same
with it as it passes in the course of its rotary motion. The position of the brush
or. pad is adjustable with regard to the bob by the rod or arm a² sliding in its
support a in which it is secured in the required position by any suitable set pin
or pins a*.
Having now particularly described the nature of my said invention and in what
manner the same is to be performed I declare that what I claim is :-
The improvements in and relating to grinding and polishing machines consisting
of the brush or pad A mounted to rotate substantially as and for the purpose herein
set forth & shewn upon the accompanying drawings.
Dated this 6th day of November 1894.
