An Improved Acetylene Gas Burner.
I, ARTHUR ROSE, of 65, Douglas Road, Handsworth, in the County of Stafford,
Gas Burner Manufacturer, do hereby declare the nature of this invention to be as
follows:
-
This invention consists of the hereindescribed improved acetylene gas burner
which is so constructed as to effectually prevent any deposit of carbon round the
hole in the burner through which the acetylene gas issues as it is burnt. This
deposit of carbon round the hole is a very serious defect in many of the acetylene
gas burners at present in use causing the burner to soon become choked and the
flame considerably diminished.
My improved acetylene gas burner is a special kind of Bunsen burner and is
constructed as follows:-
In carrying out my invention the top of the body of the burner is by preference
made conical and has a very small hole in the top through which the acetylene gas
issues. Enclosing the top of the said body I provide a hollow cap which is also
by preference made of conical shape with a comparatively large hole at the top
and is screwed or otherwise fixed to the body so as to leave a chamber or air space
between the interior of the cap and the top part of the body. Round the base of
the cap there are small air holes directed upwardly in an inclined direction
admitting air to the said chamber which air mixes with the acetylene gas as it
issues through the small hole in the body and the mixed acetylene gas and air
are burnt as they pass out through the hole in the cap.
It will be seen that the cap and the chamber prevent the flame from coming in
contact with the said small hole in the top of the body and thus any deposit of carbon
round the hole is prevented.

An improved Acety
I, ARTHUR ROSE, of 65, Douglas Road, Handsworth, in the County of Stafford,
Gas Burner Manufacturer, do hereby declare the nature of this invention and in
what' manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention consists of the herein described improved acetylene gas burner
which is so constructed as to effectually prevent any deposit or carbon round the

page_text: hole in the burner through which the acetylene gas issues as it is burnt. This
deposit of carbon round the hole is a very serious defect in many of the acetylene
gas burners at present in use causing the burner to soon become choked and the
Hame considerably diminished.
My improved acetylene burner is a special kind of Bunsen burner and is con-
structed as I will describe by referring to the accompanying drawings on which
Fig. I is a side elevation of my said acetylene gas burner; Fig. 2 is a plan of the
same; Fig. 3 is a sectional elevation of the same; Fig. 4 is a side elevation and
Fig. 5 is a sectional elevation of a modified form of the same; Fig. 6 shews how
two of my improved burners may be combined together so as to give a flat flame
and Fig. 7 is a side elevation of the double gas burner represented by Fig. 6.
The same letters of reference indicate the same or corresponding parts in all
the figures of the drawings.
I will refer firstly more particularly to Figs. 1, 2 and 3. In carrying out my
invention the top a of the body A of the burner is by preference made conical and
has a very small hole a in the top through which the acetylene gas issues. This
top part of the burner is by preference made as a refractory tip which fits into
the metal body A. Enclosing the top or tip part a¹ of the body A I provide a
hollow cap B the top b¹ of which is made of refractory material and has a com-
paratively large hole immediately over the hole a in the top a¹ and at a short
distance above the same. This cap B is screwed at 63 or otherwise fixed to the
body A so as to leave a chamber or air space marked c in the interior of the cap B
that is between the underside of the top part 6 of the cap and
the top part al of the body A. In the sides of the cap B below
the underside of the top part of the cap there are small air holes
preferably two in number marked da² to admit air to the chamber c which air
mixes with the acetylene gas as it issues through the small hole a³ in the top a¹
of the body and the mixed acetylene gas and air are burnt as they pass out through
the hole in the cap B but there is no flame in the chamber c. It will be seen
that the cap B and air chamber c prevent the flame from coming in contact with
the small hole a¹ in the top of the body A and thus any deposit of carbon round the
hole a is prevented.
Instead of the top part 1 of the cap B being flat as represented in Figs. 1 and 2
the said top part b₁ may if desired be of a hollow conical shape as represented in
Figs. 4 and 5 but I find that the form represented in Figs. 1, 2, and 3 gives the
best result.
Two of my said burners may be combined together as are other gas burners, for
instance as shewn by Figs. 6 and 7, and arranged on a branch pipe G made with
two branches marked respectively g' which are spread apart and to which the
bodies AA of the two burners are fixed inclining towards each other so that the
flames whichí issue from the two burners also incline towards each other and unite
and form a flat flame.
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:
1. In an acetylene gas burner the combination with the top of the burner body
having a very small opening for the gas, of a cap fixed to said body forming an
air chamber round said burner top and having side air inlet holes and a small
hole in the top of the cap through which the mixed gas and air issue, the parts
being constructed and arranged substantially as described.
2. In an acetylene gas burner the combination of the body A and burner top a¹
having a very small opening a³ for the gas, the cap B forming an air chamber
round said burner top and having side air inlet holes and a small hole b³ in
the top of the cap through which the mixed air and gas issue, substantially as
described and illustrated.
3. The combination of two acetylene gas burners of the kind denoted under

page_text: Claims 1 and 2 mounted on a suitable branch pipe or body so as to incline towards
each other, each of the said burners having a burner top in which is a very small
opening for the gas, a cap forming an air chamber round said burner top and
having side air inlet holes and a small hole in the top of the cap through which
the mixed air and gas issue, the parts being constructed and arranged sub-
stantially as described and illustrated by Figs. 6 and 7 of the accompanying
drawings.
Dated this 27th day of October 1898.
