IMPORTANT WARNING.

Appeal Action regarding Combustion Tube Safety Lamp Decided in favour of
Mr. Hailwood, of Ackroyd and Best Ltd.

J

■ ONE OF THE MANY FORMS OF HAILWOOD S
PATENT COMBUSTION TUBE LAMP

On the 26th November, an Appeal, case was tried at the Royal Courts of
Justice, London, when the decision was given completely in favour of Mr. E. A.
Hailwood that his Patent No. 18,694 of 1913 was a very strong and valid one,
the decision making it quite clear that the Patent for Hailwood s Combustion
Tube Lamp was not only valid for a miner’s lamp having an inner glass with
combustion tube aperture plate suspended from above, but also for an inner glass
with combustion tube aperture plate supported from below, and that his several
other modified forms are unique and safely protected by the Patent Law.

WE THEREFORE ISSUE THIS WARNING THAT
ANYONE INFRINGING

these patent rights will be dealt with as the law provides, users as well as
makers of an infringing article being liable for damages.

The sole patent rights of the Hailwood Combustion Tube Lamp are held by
Ackroyd and Best Ltd., of Morley, and this lamp can only be obtained from
such Company. Kindly note.

The Hailwood Combustion Tube Lamp has been very carefully studied out,
and is the biggest light-giving lamp on the market, and is most simple and most
easily manipulated, and is much superior to electric lamps.
