PROVISIONAL SPECIFICATION.
An Invention for Converting any kind of a Gas Burner, with or
without removing Glass Globe, into a Gas and Air Burner for
Heating or Cooking Purposes.
CARTERET MAULE Belle Vue Brewery Handsworth Birmingham, Brewer do
hereby declare the nature of this invention to be as follows:-
The invention is a small metal funnel inverted over the gas burner, the spout of
the funnel being either cylindrical or sloping outwards to the top. The base of
funnel-cone is closed by a shutter, for admitting or excluding air, composed of two
parts the one moveable and the other fixed. The fixed part crosses the middle of
the base of the funnel-cone and has fixed in its centre a cylindrical socket extending
vertically inwards of such height and diameter as will fit the gas burner, yet so as
to move on and off easily. The moveable part is a slide revolving round this socket
and of such shape as when closed it will entirely exclude all air from the funnel,
and when open will exactly coincide with the fixed part.
When used for cooking purposes a kettle stand is fitted on to the funnel. This
stand is either cylindrical or sloping outwards to the top. It extends from base of
gas globe to a little above its top and of such diameter as will enable it to just
pass easily in and out top of globe. The stand is castellated round the top and
pierced, below the level of the funnel top, with holes for the admission of air.
If desired for use without glass globe and for greater security the whole can be
clamped on to the gas burner by a screw pin running horizontally through the
side of the funnel cone and through the small cylinder surrounding the gas
burner.

An Invention for Converting any kind of a Gas Burner, with or
without removing Glass Globe, into a Gas and Air Burner for
Heating or Cooking Purposes.
I, CARTERET MAULE of Belle Vue Brewery Handsworth Birmingham,
Brewer 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 invention is in the shape of a small metal" tun-dish" or decanting.
funnel A Fig. I inverted over the gas burner with its spout pointing vertically
upwards and placed immediately over the gas burner. This spout widens at the
top to form a rose B. Fig. I in the shape of those used with the ordinary Bunsen
burner of the chemical laboratory, the top being closed by a flat metal top B B¹
Fig. 1 and the sides pierced with holes H. Fig. I which form the egress of the gas
and air. Inside this rose and below the holes is a dome of wire gauze G. G. Fig. 1
fitted closely to the side all round.

page_text: 2. The base of the funnel cone is closed by a shutter E and F in
Figs. III III IV (for admitting or excluding air) composed of two parts which
are circular metal discs, the one on the top of the other, the upper one movable and
the lower one fixed.
3. The fixed disc E Figs. I II III has in its centre a metal cylindrical socket S.
Fig. III & II which extends vertically upwards inside the funnel coue and through
which the gas burner passes.
The internal diameter of this socket is less at the top
than at the base and at its narrowest portion only just allows the burner to pass in
and out easily. Its height must not exceed that of the gas burner.
4. The movable disc F. Figs. I. IV is identical in shape with the fixed disc, but
in the place of the socket has a circular hole T. Fig. IV through which the socket
of the fixed disc passes, the socket forming the axis around which it moves.
5. Both discs have slits K. Figs. II III & IV in opposite quadrants of their
surface (for the admission of air) of such length and width as that when open, the
slits of the movable disc will exactly coincide with those of the fixed disc, and when
closed, the two quadrants of the movable disc, which have no slits cover over the
slits in the fixed disc, (and exclude air).
6. The movable disc may be turned from the outside by a peg passing through
the slit of the fixed.
7. If desired, and for greater security, and for use without the glass globe, the
invention may be made with one or more screw-pins running horizontally through
the side of the funnel cone and through the small cylinder surrounding the gas
burner, in order to clamp the whole firmly to the gas burner.
8. When the invention is to be used for culinary purposes it must have on the
outside of its rose and below the holes of the same a metal ridge R. R. Fig. I for
the support of the kettle stand.
9. This kettle-stand is a metal crown C. C. Fig. V exactly fitting round the rose
and clamped on to it by one or more screw-pins and resting upon the ridge described
in paragraph 8. Abutting from the periphery of the crown on the outside are
triangular brackets M. Fig. V of such height as to carry the kettle whit
them into the hottest part of the flames.
The periphery of the crown has holes or slots L. Fig. V coinciding
of the rose.
10. The invention may be made in any metal and in different sizes acc. 7.
the requirements of the gas barner for which it is intended. For the ordinar,
sizes of, say, a Bray's burner, the height would be about 3 inches, the diameter of
both rose and funnel-base cach about 2 inches.
11. For use without removing glass globe it (the invention) is made
way but taller, so as to carry the kettle above the top of the globe.
12. 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
For the conversion of an ordinary gas burner into a gas and air burner, with or
without removing glass globe by means of such an appliance as I have herein
described.
