PROVISIONAL SPECIFICATION.
An Improved Gas-burner.
I, WILLIAM WILSON HORN, of the firm of Horn & Son, of 151 Strand, London,
Middlesex, Patent Agent, (a communication to me from abroad by Albert G. Morey,
of La Grange Illinois, United States of America, Inventor,) do hereby declare the
nature of this invention to be as follows:-
This my invention relates to a new and improved gas burner, and which invention
bas for its object to provide a burner which will give increased light with a relatively
small consumption of gas.
In constructing a burner in accordance with this invention, I provide an ordinary
gas bracket, upon the end of which I secure by any suitable means, a small hollow
chamber. Around this hollow chamber is another cylindrical chamber, which is open
at the top and is connected to the firstnamed small hollow chamber by small tubes.
In the upper end of the first-named chamber is fitted a hollow plug, in which is secured
a conical spreader. This conical spreader is hollow, and has a downwardly inclined
rim which projects over the cylindrical chamber aforesaid. A circular plate having
upwardly turned flanges is secured to the cylindrical chamber, and serves to support
a glass chimney.
In operation, the gas passes through the bracket into the first-named small hollow
chamber, and through the small horizontal tubes into the aforesaid cylindrical cylinder,
and burns around the upper part thereof. The flanges upon the conical spreader,
extend the flame, and thus cause a better light.
Dated this 8th day of March 1890.

An Improved Gas-burner.
I, WILLIAM WILSON HORN of the firm of Horu and Son of 151 Strand in the County
of Middlesex Patent Agent do hereby declare the nature of this invention (a_com-
munication from Albert G. Morey of La Grange in the State of Illinois United States
of America Inventor) and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :—
My invention has relation to gas-fixtures of that class in which an Argand burner
is employed in conjunction with a device for spreading the flame for the purpose of
causing complete combustion of the gas as it escapes from the apertures in the burner ;
and it consists in the improved construction and combination of parts of a gas-burner
of that class, substantially as will be hereinafter more fully set forth.
Like letters of reference denote corresponding parts in the several figures.
Figure 1 is a perspective view of my improved gas-fixture complete.
Fig. 2 is a vertical trausverse sectional view of the same.
Fig. 3 is a plan or top view of the Argand burner, which forms a part of my
improved fixture.
Fig. 4 is a sectional detail view of the Argand burner, showing the cap or socket
detached from the main part of the burner.
Fig. 5 is a perspective view of my improved flame deflector or "spreader ;" and
Fig. 6 is a similar view of the foraminated globe-holder, which forins a part of my
improved fixture.
In the accompanying drawings, the letter A designates the arm or bracket of a
gas-fixture of any desired construction provided with the usual externally-threaded

page_text: orifice B, adapted to receive the burner. A so-called "Argand" burner C is secured
upon the fixture, so as to feed the gas into an annular receptacle provided in its upper
end with a series of small apertures, as usual in that class of burners. The central
part of the burner C consists of a cylindrical chamber D, from which the gas is fed to
the burner proper through the branch pipes E, and the chamber D is open at its upper
end and provided with an interior screw-thread to adapt it to receive a plug or cap F,
the inner part of which forms a recess or socket G, adapted to receive the tenon H
of the flaine-deflector or spreading device I. The construction of the latter will be
readily understood from the drawings, from which it will be seen that it consists of a
circular disk supported upon an inverted cone and having its outer rim deflected or
turned downwardly, so as to overlap the burner. The angle formed by this deflected
outer rim, which is preferably a sharp angle, is placed directly over the openings in
the burner C, so that as the flame passes upward it strikes the deflector within this
angle and is thrown downward and outward, thereby causing the rays of light to be
deflected downward and outward from the spreader, aside from the manifest advantage
in obstructing and spreading the flame to such an extent that more complete
combustion is obtained than would be without the deflected portion of the rim.
This "spreader," so-called, may be made of any desired material; but for my
particular purpose I prefer to make it of a composition consisting of a mixture of
refined clay or terra-cotta, asbestos, and manganeso, mixed in suitable proportions and
moulded into the proper shape. Not only is this material practically indestructible
by heat, but after it becomes thoroughly heated it becomes to a certain extent
incandescent and reflects its own light through the thin film of flame encircling it,
thus giving a peculiarly white and pure light, which cannot be attained, as far as my
experience and experiments go, by the substitution of other material.
The body of the burner C is provided at its lower part with an annular rim or
flange, forming a support for the foraminated chimney-holder K. The latter is
struck up from a single piece of perforated sheet metal and provided with an inner
and outer upwardly-turned flange, (denoted by the letters L and M, respectively).
The outer flange M fits closely around the lower rim of the globe or chimney N,
and may be provided with a set-screw or any other of the well-known means for
binding the globe in position and preventing it from falling off.
By making the cap I removable it can be taken off at any time to he replaced by
different ones or to remove any obstructions of any kind that should happen to get
into the burner.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The herein-described gas-fixture, consisting of the arm or bracket, the orifice
connected bereto, the cylindrical chamber having the depending portion connected to
said orifice, the plug fitting in the upper end of the chamber, the conical spreader
fitting in the plug and having the downwardly-inclined rim, the burner-body
consisting of the plate having the flanges at the upper and lower ends and the plate
secured in place by said flanges, and the chimney-holder having the inner upturned
edge supported on the body and the outer inclined edge for surrounding tlie lower
edge of the burner, substantially as described.
2. In a gas-burner, the combination of the cylindrical chamber, the burner com-
municating therewith having the flange at the lower end thereof, the plug fitting in
the said chamber, the conical spreader fitting in the plug and having the downwardly-
inclined rim, the chimney-holder supported on the flanges of the burner and having
the inner rim surrounding the burner and the outer inclined peripheral rim
surrounding the chimney, substantially as shown.
