PROVISIONAL SPECIFICATION.
Improved Apparatus for Automatically Polishing the Bowls of
Glazing-calendering Machines.
I CHRISTOPHER SLACK of Bank Vale Hayfield, near Stockport, in the County
of Derby, Paper Manufacturer, do hereby declare the nature of this invention to
be as follows:-
Paper makers, calico printers, finishers and other manufacturers who use what
are called "glazing callenders" have to keep the top callender bowl well polished
and bright or the finish which they wish to impart to the goods will be dull and
unsatisfactory. All "glazing callenders” running twelve or fourteen hours get
dull on the top bowl, consequently the finish to the goods glazed or tinished is dull
but by applying this polisher to the top bowl for a few minutes the bowl is made
bright and whilst being polished this machine keeps the top bowl true as the
pressure put on travels across with the pressure even and regular and prevents it
from getting out of truth. The machine consists of a turned thread screw and a
square bar with fixing and block, attached to the same are three pulleys fast and
loose for driving, the motive power being taken from the callender itself by a
strap.
•
The block is filled with a lead lined piece of hard wood fitted in the block by a
V groove and tongue so that it is easily put in or taken out. This block is set in
motion by the pulley turning the screw which is kept parallel and firm by the
square bar which is also fitted so that the block slides on it. The block is then
pushed up to the bowl by two screws at either end, which can be screwed to any
degree of tightness; emery and oil, or other suitable polishing material or
compound, is then put on the block which works across the bowl to the other end,
a set screw then comes against a rod, which pushes the strap to the other pulley,
which then brings it back across the face to the other end, the said screw and a
weight being used to turn the strap again which acts automatically from side to
side. When sufficiently polished the strap is put on the loose pulley, the block
unscrewed away from the callender, and the wooden block removed. The callender
is then wiped dry and is ready to commence glazing. As the polisher is a
permanent fixture to the callender it can be set to work when next wanted in two
or three minutes so that by this combination all the parts work together and the
bowl is not only polished but kept in truth and worn equally across by its process
of polishing.

Improved Apparatus for Automatically Polishing the Bowls of
Glazing-calendering Machines.
I CHRISTOPHER SLACK of Bank Vale Hayfield, near Stockport, in the County
of Derby, Paper 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 :-
Paper makers, calico printers, finishers and other manufacturers who use what

are called “glazing callenders" have to keep the top callender bowl well polished
and bright or the finish which they wish to impart to the goods will be dull and
unsatisfactory. All "glazing callenders" running twelve or fourteen hours get
dull in the top bowl consequently the finish to the goods glazed or finished is dull
but by applying this polisher to the top bowl for a few minutes the howl is made
bright and, whilst being polished, the top bowl is also kept true.
The object of this invention is to construct an improved apparatus which shall
keep the top bowl of such machines always polished and true.
The nature of my invention and the manner in which the same is to be performed
or carried into practical effect will be readily understood on reference to the
annexed three sheets of drawings and the following explanation thereof.
Fig. 1 is a front elevation of the driving end of the apparatus and Fig. 2 is a
similar view of the other end of the same. Fig. 3 is a transverse sectional view
of the same.
The machine consists of a turned thread screw a and a square bar passing
through sliding bearings in the fixing e and having a block d attached to the same,
with three pulleys e one fast and two loose for driving; one of the driving straps
is crossed and the other open so that by bringing either the one or the other onto
a fast pulley the motion of the screw is reversed, the motive power being taken
from the callender itself or from shafting above by the straps.
The block d is filled with a lead lined piece of hard wood fitted in the block by
a V groove and tongue so that it is easily put in or taken out. This block d is set in
motion by the fast pulley turning the screw a which is kept parallel and firm by
the square bar which is also fitted so that the block & slides on it. The block d.
is then pushed up to the bowl (see Fig. 3) by two screws gone at either end, of
the bar b and acting on the sliding hearings thereof by which it can be screwed
to any degree of tightness. Emery and oil or other suitable polishing material or
compound is then put on the block which works across the bowl to the other end,
a projection carried by the block d then comes against a collar fixed by a set
screw on a rod which pushes the other strap to the fast pulley which then brings
the polishing block across the face of the bowl to the other end; the said
projection and a weighted lever being used to move the straps quickly &
automatically from side to side. When the bowl h is sufficiently polished the
straps are put on the loose pulleys the block d unscrewed away from the callender
bowl and the wooden block removed. The callender is then wiped dry and is
ready to commence glazing. As the polisher is a permanent fixture to the callender
it can be set to work when next wanted in two or three minutes so that by this
combination all the parts work together and the bowl is not only polished but kept
in truth and worn equally across by its process of polishing.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The combination with a glazing-calendering machine of an automatic apparatus
(constructed and operating substantially as hereinbefore described) for polishing
the top bowl thereof, such apparatus being permanently attached thereto and
capable of being moved into or out of action as required.
