AN IMPROVED BURNER FOR GAS FIRES
Year: 1882

page_text: LETTERS PATENT to Benjamin Verity, of the Firm of Verity Brothers, of
Saint Paneras, in the County of Middlesex, for an Invention of "AN
IMPROVED BURNER FOR GAS FIRES."
PROVISIONAL SPECIFICATION left by the said Benjamin Verity at the
Office of the Commissioners of Patents on the 3rd February 1882.
BENJAMIN VERITY of the Firm of Verity Brothers of Saint Pancras in the.
County of Middlesex. " AN IMPROVED BURNER FOR GAS FIRES."
My Invention relates to improvements in the burners for gas fires, made of fire
clay or a mixture of fire clay and silicate, or of other plastic material, and it has
for its object to facilitate the manufacture of the burner, to afford the necessary
freedom for expansion and contraction and prevent fracture, to ensure a more
complete and intimate mixture of the gas and air, and to raise the temperature of
the gases before they enter into combustion.
The burner is of that class which has heretofore been moulded in one piece with
a single internal chamber from which perforations lead out through the walls of
the chamber at which the gases issue and burn in contact with the walls of the
chamber and with imitation fuel moulded upon or packed around it.
My present Invention consists in constructing the burner (whether it have one
internal chamber as hitherto, or two as hereafter described) of a number of
sections or parts fitted together, and it also consists in constructing the burner
with two chambers, an upper and a lower one, each extending the whole length of
the burner and communicating with one another at the ends. The walls of the
burner are perforated in all directions, all the perforations leading out from the
upper chamber only. The burner may be composed of any desired number of
sections according to its length or size, the joints being transverse or otherwise,
and the sections being moulded with flanges on one side around the apertures of
the chambers, and with sockets on the other side to receive the flanges of the
adjacent section and form a sufficiently tight joint which may be luted if desired.
The several sections may be bound together by a metal strap or clamp extending
along the bottom and embracing the ends of the burner and secured thereto in any
suitable manner. This metal strap may be made in one with or attached to a
hollow boss or bulb fitted in a socket in the bottom of the middle section or
sections of the burner and leading into the lower or mixing chamber, the gas inlet
being connected to it in any suitable manner.

the said Benjamin Verity in the Great Seal Patent Office on the 27th July
1882.
BENJAMIN VERITY of the Firm of Verity Brothers of Saint Pancras in the
County of Middlesex. "AN IMPROVED BURNER FOR GAS FIRES."
My Invention relates to improvements in the burners for gas fires, made of fire
clay or a mixture of fire clay and silicate, or of other plastic material, and it has
for its object to facilitate the manufacture of the burner, to afford the necessary
freedom for expansion and contraction and prevent fracture when in use, to ensure
a more complete and intimate mixture of the gas and air, and to raise the
temperature of the gases before they enter into combustion.
The burner is of that class which has heretofore been moulded in one piece with
a single internal chamber and perforations leading out through the walls of the
chamber at which the gases issue and burn in contact with imitation fuel moulded
upon or packed around the burner. Such burners have been liable to fracture
owing to the unequal heating and the consequent unequal expansion at different
parts of their length when in use.
My present Invention consists in constructing the burner (whether it have one
internal chamber as hitherto or two as hereafter described) of a number of sections
or parts juxtaposed and fitted together, and it also consists in constructing the
burner with two chambers, an upper and a lower one, extending the whole length
of the burner and communicating with one another at the ends, the gas and air
being supplied to the lower chamber where they become thoroughly-mixed and
heated before entering the upper chamber whence they are distributed through
perforations radiating from the upper chamber only, through the walls of the
burner.
In order that the Invention may be more readily understood I have illustrated
an example thereof in the accompanying Drawing and will proceed to describe the
construction of the burner in detail with reference thereto. Figure 1 is a front
elevation of the burner partly denuded of the artificial fuel which would usually
be moulded upon the front and top surfaces of the sections. Figure 2 is an end
elevation. Figure 3 is a central longitudinal section and Figure 4 is an end view
of one of the sections of the burner. Figure 5 represents a fire place the grato bars
and "fuel" being partly removed to show the burner in position therein.
The burner is composed of any desired number of sections A. according to its
length or size the joints a between the sections being transverse or otherwise.
B is the upper chamber and C is the lower chamber running horizontally the one
above the other and connected at the ends as shown in Figure 3 the intermediato
and end sections being respectively moulded of the forms shown and the joints
being made by flanges b, c on the one section around the apertures of the
chambers B, C, being received in corresponding sockets on the other section as
shown, the joint being luted if necessary. d are the perforations radiating from
the upper chamber B to different points of the front and top surfaces as shown in
Figure 4 these perforations opening into hollows or corrugations formed in theso
surfaces. The sections are moulded of this form and the imitation fuel which
may also be perforated is applied over the corrugations and baked on the sections
or it may be packed around the burner after it is placed in the fire place, d¹ are
perforations leading out from chamber B through the ends of the burner. The
several sections are bound together by a metal strap or clamp. Extending along
the bottom and embracing the ends of the burner and secured thereto in any
suitable manner. This metal strap may be made in one with or attached to a

page_text: hollow boss or bulb F. fitted in a socket in the bottom of the middle section or
sections of the burner and leading into the lower or mixing chamber C as shown the
gas inlet G being connected to it as shown or in any other suitable manner. H, is
the air inlet the whole forming a Bunsen burner. K are the ordinary grate bars of
the fire place on which the burner simply rests as shown in Figure 5. It will be
seen that the burner is complete in itself and requires no fitting. The sections A
are securely bound together by the clamp E and the bulb F if made separate
therefrom is screwed into its place before the burner is put into the fire place, the
gas inlet being connected afterwards.
Having described the nature of my Invention for "An Improved Burner for
Gas Fires" and the manner of performing the same I declare that what I claim
as my Invention to be protected by the hereinbefore in part recited Letters
Patent is
1st. The improved burner for gas fires constructed substantially as herein shown
and described.
2nd. The construction of a burner of the kind described of separate sections
juxtaposed and fitting together substantially as herein shown and described.
3rd. The construction of a burner for gas fires with two longitudinal internal
chambers the one above the other connected at the ends, and with perforations
radiating from the upper chamber substantially as shown and described.
4th. The combination with a burner for gas fires constructed in separate sections
as herein described of a metal clamp or strap embracing and binding together the
whole of the sections and provided with a bulb for the inlet of gas and air
substantially as herein shown and described.
In witness whereof I the said Benjamin Verity have hereunto set my hand
and seal, this Twenty fifth day of July A.D. 1882.
