IMPROVEMENT IN APPARATUS FOR BURNING OFF OLD PAINT
Year: 1885

page_text: I, ERNEST COLDWELL, of 47 West Parade, Huddersfield, Yorkshire Painter,
& Paperhanger do hereby declare the nature of my invention for IMPROVEMENT
IN APPARATUS FOR BURNING OFF OLD PAINT, to be as follows:-
My invention consists of copper and iron or other suitable materials so shaped
and placed as to act as a shield from the wind and reflector and storehouse of heat,
which is obtained from an ordinary Bunsen or other burner connected with a gas
supply by means of an ordinary india-rubber or other tube.
In the accompanying drawings Fig. 1 represents a sheet of copper or other
material shaped somewhat like a box with the front entirely open and a small
opening A at the back near to the bottom through which the burner is placed.
Fig. 2
represents a metallic grate which is to be placed over the open front of
Fig. 1. The flame from the burner plays through this grate which prevents the
rapid escape of heat and becomes hot. The heat is reflected in the required
direction by the copper at the back.
The apparatus is applied to the surface of paint which is to be taken off which
it renders soft so that it can be scraped off in the usual way.
The grate can be removed and the apparatus used without it whenever it is
thought desirable.

I, ERNEST COLDWELL, of 47 West Parade, Huddersfield, Yorkshire, Painter
Paperhanger &c. do hereby declare the nature of my invention for IMPROVE-
MENT IN APPARATUS FOR BURNING-OFF OLD PAINT and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
"
My invention consists of apparatus (to be herein after described) which is placed
in conjunction with a "bunsen or other heating burner for the purpose of
shielding it from the wind and preventing the rapid escape of heat in directions
where it is not required.
"
In the accompanying drawings, Fig. 1 gives a sectional view of a shield C (made
of copper or other suitable material) placed in conjunction with a " bunsen
burner D which is provided with a wooden handle E, hollowed out, and the end
covered with a perforated disc Fig. 2 for the gentle admission of air, where a gas
and air burner is used. On the inside of the shield there is a rim H projecting
from the burner: this rim is cut into sectional tongues so that the flame will not
be easily blown out, it may be covered with a little wire gauze when necessary to
prevent "lighting back." The shield may be made the shape indicated in the
drawings or any other convenient shape.
Fig. 3 is a metallic grate (preferably of copper and iron: horizontal wires copper,
and iron for perpendicular wires) which is placed (as shewn in section at F Fig. 1)
in the open front of the shield a view of which is given as seen through the grate
Fig. 3. The grate may be of woven wire in order to hold it together, or, of
parallel or other bars fastened together by any simple means, the grate may be
removed whenever it is thought desirable.
When connected with a supply of gas it is to be applied to the surface of paint
to be taken off, which is rendered soft by the heat so that it may be scraped off in
the usual manner.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is,
A combination substantially as specified-consisting of a shield with rim H cut
into sectional tongues together with a metallic grate Fig. 3, and hollow handle E
covered at the end with a perforated disc Fig. 2 to be placed in conjunction with a
bunsen or other heating burner for burning-off paint (no claim being made in
respect of such burner) in order to shield it from the wind and prevent the rapid
escape of heat in directions where it is not required.
