IMPROVEMENTS IN GAS BURNERS FOR HEATING PURPOSES
Year: 1884

page_text: I WILLIAM GEORGE APPLEFORD of No 74 Bradford Street Birmingham in the
County of Warwick Manager of Works do hereby declare the nature of my said
invention for " IMPROVEMENTS IN GAS BURNERS FOR HEATING PURPOSES" to be as
follows that is to say :-
"3
My Invention has for its object "Improvements in burners for heating purposes
which are designed mainly for the purpose of burning gas and air mixed on the
well known principle of the atmospheric burner but direct, from the gas pipe may
of course be used if preferred.
My improvements are as follows:-I make a cast metal frame either square
oblong or round with projecting feet or otherwise at the corners or other positions
with wrought screws or other arrangements cast in for securing the burners in
their positions. Now in this frame I cast a certain number of fast bars or par-
titions which pass either longitudinally crosswise or diagonally and at such a
distance apart as there is just sufficient space to receive a notched or fluted bar
between each bar. When these notched or fluted bars are drooped in from the
back or front of the burner the whole surface is made porous with great regularity
and precision and the spaces are kept constant and firm and the whole burner is
a firm and substantial casting well tied together with these cress bars. The loose
intermediate bars are for increased stability: made deeper at the ends than the
middle and the bottom edges are chamfered or tapered so as to afford greater
facility for the gas and air to pass into all parts of the burner.

My Invention has for its object improvements in gas burners for heating pur-
poses which are designed mainley for the purpose of burning gas and air mixed
on the well known principle of the atmospheric burner but direct from the gas
pipe may of course be used if preferred.
My improvements are as follows:-I make a cast metal frame either square
oblong or round with projecting feet or otherwise at the corners or other positions
with wrought screws or other arrangements cast in for securing the burners in
their positions. Now in this frame I cast a certain number of fast bars or par-
titions which pass either longitudinally crosswise or diagonally and at such a
distance apart as there is just sufficient space to receive a notched or fluted bar
between each bar. When these notched or fluted bars are drooped in from the
back or front of the burner the whole surface is made porous with great regularity
and precision and the spaces are kept constant and firm and the whole burner is
a firm and substantial casting well tied together with these cross-bars. The loose
intermediate bars are for increased stability made deeper at the ends than the
middle and the bottom edges are chamfered or tapered so as to afford greater
facility for the gas and air to pass into all parts of the burner.
In order that my invention may be the better understood and carried into
practice with facility I have attached hereunto a sheet of drawings containing
a number of views of my invention applied to an actual gas burner which is
suitable for beating a kettle or other similar pan or vessel.
Figure 1. is a perspective view of the burner and stand.
Figure 2. is a plan of the burner removed from the stand.
Figure 3. is a sectional elevation of the burner on line A. B.
Figure 4. is a sectional elevation on line 'C. D.
Figure 5. is a side elevation and plan of one of the removeable bars.
The frames from which I make my burners are perhaps better seen at Figure 2.
than on any other view. The frame E and bars F are cast in one piece together
as one casting or frame and therefore the diversions or spaces H are regular and
accurately preserved against variation or falling to pieces. Now from the under
side of the frame I slide into each of these spaces H a bar K such as the one shown
separately by Figure 5. Two are also shown in positions by Figure 2 and Figure 3
and in the case of the perspective view Figure 1 all the bars are in position showing
the perforated face. The bars K slide up against the shoulders m and may be
taken out and renewed or cleaned at any time. The hollows of flutes v may.
be made of any shape desired. ...
The stand N may be made of any desired pattern or design as the upper part
can be attached to any base by the screws W so that when the parts are screwed
together the bars K are locked in their position. The gas enters at P mixing with
the atmosphere and is burnt on the surface. The pan or other article to be heated
stands upon the legs, R. S. T. U. but the design of this part may be altered to
either round, squaro, oval or other shape and a three or more legs.

page_text: 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
1 claim is:
The improvements in burners for heating purposes of the solid or fast frame E, F
whether made square, oblong round or other shape with the supplimental bars K
to form the porous surface substantially as herin set forth.
