GEORGE EDWARD WEBSTER, C.E., of the Central Chambers, Market Street, in
the Town and County of the Town of Nottingham, Civil and Gas Engineer, and
WILLIAM EDWARD FISHER, of Villa Road, in the Town of Birmingham, of the Firm
of James Barwell, Son, and Fisher, Worcester Works, Clement Street, in the Town
of Birmingham, Chandelier and Gas Fitting Manufacturers. "IMPROVEMENTS IN
GAS BURNERS, GOVERNORS, AND STREET-LANTERNS."
In the first part of our Invention relating to gas-burners we refer to improve-
ments relating to the Letters Patent, No. 1032, March 15th, 1878, granted to one
George Edward Webster, C.E,, of Nottingham. and the joint inventor of this
Invention, whereby the current of air passing between the two sheets of flames is
regulated and fixed according to definite proportions for the quantity and quality
of gas used through given sizes and kinds of burners; this we do by employing
certain fixed and defined distances for each size of burner between the pairs of
orifices, as described in the aforesaid Specification; also in the method of man-
facturing the said duplex or other burners having two or more nibs by rolling
the same into the cup; this we do by leaving a check at the bottom of the metal
cup and rolling the sides over; also in glazing the surface of the part rolled in, and
into which are fixed the nibs, between which we sometimes find it advantageous to
place a strip of metal; also in the method of securing the said burners to the
triangles by means of a small nut placed under the triangle which is bored clear,
and thus securing the triangle; also by combining a chimney, which may be of a
similar character to that used in the argand burners, or of an oval section, with
the burners, placing this chimney over the flame so that it reaches some distance
down, but not entirely, this by producing a stronger current of heated air
strengthens the flame, and causes a steady-light. The exact position of the chimney
is determined by the pressure and size of the flame with which it is combined.
We fix the chimney frequently so that the bottom of it is nearly at the top of the
flame and extending from there upwards; the position is of importance, and an
increase of illuminating power may be obtained, whereas should the circumstances
of the pressure of gas supplying the burner and the position of the chimney be
unsuitable there is a decrease; we therefore adjust the position and size of the

page_text: chimney to the circumstances of the burner or make it movable, as more completely
described in our final Specification. This burner we place in our improved street
lanterns for street lighting, which said lanterns or lamps are composed of incline
tops, preferably of opal, and clear glass bottoms; we place the opal sheets close to
the new chimney, which we make either of glass or metal.
In connection with the street lamp, and also for burners on chandeliers, and in
simple connection with a series of burners on a service, we employ a gas regulator
or governor, constructed of two flat discs having at their edges an oil joint, with
the sides of the inside of the governor, and which by their movement regulates the
supply of gas to the burner or burners and are themselves double acting.
We also make the governor with one small floating disc; this form we believe
more suitable for small governors.
