PROVISIONAL SPECIFICATION.
Improvements in Cleaning and Annealing the Wires of Paper
Making Machines.
GEORGE TANKARD Chorley Mills Engineer and Paper Merchant Park Lane
Leeds. I do hereby declare the nature of this invention to be as follows :-
This invention consists of the application of burners for gas or other suitable
substances for the purpose of annealing and cleaning the copper or wire gauze for
the spreading of paper pulp on paper making machines.
To consist of atmospheric burners blow or ordinary fast burners burners in
rows, equal to width of wire on machine.
To burn coal or oil gas or any other heating substance and air in proper pro-
portions either under pressure or without pressure according to strength of wire
on machine.
After heating wires on burners to pass into water in vacum box to cool the
wire, and have a rocking motion given to same by cam or crank, so that burners
do not heat wire on same place, but play the flame equal over all the surfaces of
wires.
To have brush laid on wire equal to width of wire and have revolving motion
or rocking motion given to same to scrub dirt off on wire, after passing through
water or before doing so.

Improvements in Cleaning and Annealing the Wires of Paper
Making Machines.
GEORGE TANKARD Paper Merchant Chorley Mills Park Lane Leeds. I 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:
1. The object of this invention is the cleaning of the mesh of the wire gauze
used for spreading paper pulp on paper making machines, whilst in position or
off machine, and consists of the application of heat preferably in the form
of burners for coal gas or other suitable inflamable gas or other heating
substance.
2. The apparatus consists of high power atmospheric Bunsen gas burners (blast
burners, burning under pressure or natural conditions,) arranged in rows, or series
of small burners to form a continuous flame equal to width of wire web to be
cleaned while on or off machine.
3. The working of the apparatus is as follows: The burners are placed under
the wire on the bottom side of the wire web, extending across according to width
or on top of wire gauze.

page_text: 4. Above the burners on the top side of the wire web is placed a deflecting plate,
extending the length and width of the burners and composed of fire-clay slabs or
other refractory and non conducting material, thus forming a furnace.
5. Behind the furnace and fixed on the paper machine is placed a brush equal to
width of wire web revolving against the wire, and at the same time having a
lateral motion, or water, steam jet or other blowers for cleaning dirt out.
6. Behind the brush is placed a set of three straightening or flatting rollers
arranged across the machine the width of the wire web.
7. The paper making machine is then set slowly in motion causing the wire web
to travel between burners and deflecting plate at such a speed as to allow being
heated to dark red or the necessary heat required.
8. As it passes through the furnace on reaching the vacuum box on the paper
making machine, the water cools the wire and the revolving brush scrubs dirt
out of mesh of wire.
9. The wire then passes through straightening or flatting rollers which
straightens and takes out all kinks in wire.
10. To further illustrate the nature of my invention, I have attached hereunto
a sheet of drawings which I will now explain.

is applied.

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:
1. The cleaning and annealing of wire gauze on paper making machines for the
spreading of paper pulp by the application of heat either on or off machine.
2. The use of Bunsen gas burners blast burners or other heating substances,
burning either under pressure or natural conditious, or with or without deflecting
plate, or in combination.
3. The application of revolving brushes, or water, or steam jet or other blowers
for cleaning dirt out of mesh in combination with heat.
4. The cleaning of the wire web by the combination of heat, brushes or jets
whilst in position on paper making machine, or off machine.
