PROVISIONAL SPECIFICATION.
New and Improved Gas Burner, Particularly Applicable to
Bookbinders' Presses.
I FREDERICK MATHEWS of 69 Goswell Road in the City of London Engineer and
Machinist do hereby declare the nature of this invention to be as follows:-
The object of this invention is to produce a burner which will consume less gas, and
throw out more heat with a given consumption of gas than is obtainable with
atmospheric burners as at present constructed.
According to this invention I attach to the burner a mixing chamber having two
orifices capable of being closed by suitable cocks-one of these cocks admits gas and
the other air to the mixing chamber. The gas is conducted from the main or other
reservoir to the mixing chamber by suitable tubing in the ordinary way.
The air to support combustion I force into the mixing chamber and thence to the
burner by a fan or other suitable means for supplying air under pressure thus
obtaining more perfect combustion of the gas and consequently more intense heat.
If desired to enable the burner to be worked as an ordinary atmospheric burner as
well as with an air blast I provide an orifice in the mixing chamber closed (when the
air is supplied under pressure) with a suitable cap which cap is removed when desired
to work as an ordinary atmospheric burner the air entering the mixing chamber by
means of the said orifice in the usual way instead of by means of a blast.
I also provide in some cases a regulating cock between the mixing chamber and
the burner.
By using burners constructed as above and burning downwards with an air blast
I obtain a much more intense heat and even distribution of the same over the bottom
of bookbinders and gold blockers heater boxes for example, these burners are
applicable to existing heater boxes for bookbinders presses and effect a great saving of
gas and also time in heating up such heater boxes ready for work.

FREDERICK MATHEWS 69 Goswell Road in the County of London, Engineer
Machinist and Millwright do hereby declare the nature of this invention and in
what manner the same is to be perforined, to be particularly described and ascertained
in and by the following statement:-
The object of this invention is to produce a burner which will consume less gas and
throw out more heat with a given consumption of gas than is obtainable with
athmospheric burners as at present constructed. According to this invention I attach
to the burner a mixing chamber A having two orifices B & C capable of being closed
by suitable cocks D & E one of these cocks E admits gas and the other D air to the
mixing chamber A the gas is conducted from the main or other reservoir to the mixing
chamber A by suitable tubing in the ordinary way-The air to support combustion
I force into the mixing chainber A and thence to the burner F by a fan or other
suitable means for supplying air under pressure thus obtaining more perfect

combustion of the gas and consequently more intense heat.
the burner to be worked as an ordinary athmospheric burner, as well as with an air

page_text: blast, I provide an orifice G in the mixing chamber A, closed, when the air is supplied
under pressure, with a suitable cap which cap is removed when desired to be worked
as an ordinary athmospheric burner, the air entering the mixing chamber by means
of the said orifice after removing the cap in the usual way, instead of by means of a
blast.
I also provide in some cases a regulating cock between the mixing chamber A and
the burner F...
By using burners constructed as above and with burners burning downwards with
an air blast, 1 obtain a much more intense heat and even distribution of the same
over the bottom of bookbinders and goldblockers heater boxes, for example the
burners are applicable to the existing heater boxes of bookbinders presses and effect a
great saving of gas and also time in heating up such heater boxes ready for work.
This is also applicable to clothworkers' calenders and also to gas cooking and heating
stoves.
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 novelty of the air being driven under pressure into contact with the gas,
thus causing a greater volume of heat without increasing the consumption of gas.
2. By removing the cap the burner is converted from an air blast into an ordinary
athmospheric burner.
3. That by the flame burning downwards the heat comes into direct contact with
the bottom of the said heater box and is evenly distributed over the same.
Dated this 13th day of May 1890.
