Gas Lamps.
I, OLIVER IMRAY of No. 28 Southampton Buildings, Chancery Lane in the County
of London, Fellow of the Institute of Patent Agents, 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 :-
This invention involves the use of a finely woven or braided platinum, wire, basket,
cone, cylinder or thimble, in combination with a compound burner for burningigas
and air, or in connection with an ordinary burner designed for the combustion of fuel
gas, water gas; or any other gaseous substance capable of producing: a high degree of
heat, by which the platinum cone or thimble can be maintained at a high degree
of incandescense, and it consists of the construction, combination and arrangement
of parts disclosed in the following specification, reference being had to the.
accompanying drawings which form a part thereof, and in which similar letters of
reference indicate like or equivalent parts wherever found throughout the several
views.
Fig. 1, represents the improved incandescent gas burner, in.elevation:
Fig. 2, represents a chimney holder, used in connection therewith.
Fig. 3, represents the platinum cone or thimble employed.
Figs. 4 and 5, represent details in the construction of the improved burner..
Fig. 6, represents an article frequently employed in connection therewith: .
Fig. 7, is a central, 'vertical section of the construction shown in Fig. 1.
Fig. 8, is a modification of the form of the platinum wire cone for, thimble also
shown in Fig. 1, and
Fig. 9, shows a modification of the improved burner in central vertical:section.
Referring to figure 1, of the drawing, A, indicates the body of the burner, which is
composed of a series of hollow tubes t, each of which is provided with small. holes.or
perforations t, near the bottom, as shown. The tubes t, are attached to the burner
head shown in figure 4, which consists of a base portion d, provided with a screw
threaded shank or socket a, by which the burner may be attached to an ordinary gas
pipe or fitting, and an annular banda, which is united to the base, portion in any
desired manner.
Within the outer or annular portion of the base d, is formed an
annular chamber u, which communicates with the gas passage in then socket a, by
means of small passages c, through arms attached to the socket and forming part of
the burner head, and between these arins are open spaces through which air passes to
the inner surface of the burner in the well known way. s, indicates a series of, small
short tubes firmly attached to the burner head and communicating with the annular
chamber u. One of these short tubes fits within each of the burner tubes t, when
the latter are in place, and the top thereof should extend up to or slightly above the
holes t¹.
H, indicates a cone, cylinder or thimble, formed from platinum wire, woven or
braided into the desired shape, and the bottom of this cone is provided with a metallic
band o, having small hooks o¹, to which the strands or threads of platinum wire. are
attached. Small perforations may be substituted for the hooks o', if desired, or the
cone or thimble may be attached to band 0, in any desired manner. The threads or
wires of platinum from which the cone H, is formed may be attached at the top:to a
mica plate h, as shown in fig. 8, or be carried up and united at the top in the ordinary
basket form, these details constituting no part of this invention.
A rod r, attached to the center of the burner head, as shown in dotted lines in
figure 4, extends up centrally within the burner and upon or near the top of this rod

page_text: is placed a small plate in, proferably of mica or platinum, the object of which is to
retain the top of the cone in its proper position and prevent as much as possible,
the crushing or indentation of the same in which the mica plate h, also aids when
the latter is used.
In figures 1, and 2, is shown a chimney holder particularly adapted to this style
of incandescent burner. It consists of a band b, provided with spring wires or rods n,
attached thereto, in any desired manner, and being curved outwardly and extended
upwardly as shown, and of an annular band e, attached to said rods and supported
thereby. Each of the rods n, is provided at its top with a short projecting portion y,
which extends outwardly at right angles to the vertical portion thereof and the band e,
is provided on its inner surface, with small holes or perforations which are designed
to receive the outwardly projecting portion y, of the rods n. The band e, is placed in
position by simply taking hold of the rods n, and pressing them together until the
projections y, will pass within the hand, and are brought opposite the holes in the
inner surface thereof, when upon releasing the rods the projections y, will enter said
holes and the band e, will be held firmly in position.
The platinum cone, cylinder or thimble is extremely frail and delicate and liable to
be crushed out of shape by the slightest touch, and this would be liable to occur every
time the chimney was removed or put on if an ordinary chimney holder were
employed; by the use of the improved holder, however, all this is avoided. The end
of the chimney is placed within the band e, from above and the rods n, guide it, as it
is passed down over the cone and it is impossible for the chimney to strike or come
in contact therewith, and the same is true when the chimney is removed.
When the platinum cone is in position upon the burner, the band o surrounds the
top thereof and the circular row of tubes which composes the burner, open just within
said band. This band serves to keep the cone in position upon the burner, around
the combustion chamber, and to maintain the base thereof in a circular shape. If,
however, the body of the cone should be crushed, indented or otherwise gotten out of
symmetrical form by handling, shipping or otherwise, a small 'conical shaped block
similar to that shown in figure 6, inserted through the base ring o, and pressed gently
upward to the top of the cone will restore it to its original and proper shape, and this
may be done as often as necessary. The cone may be removed from the burner
whenever desired by taking hold of the pin P, secured to the top of the cone and
which extends down into the top of the rod r, which is hollow at the end for this
purpose, and pressing upwardly upon the band o, until it slips from over the burner
tubes; the pin P, is also provided with a shoulder or enlarged portion which fits
within the top of the rod r. and on which the platinum plate h, rests. The band b, of
the chimney holder, serves as a support for the band o, of the cone and prevents the
same from slipping downward.
The
The operation is as follows: gas enters the tubes t, by the passages v, in tubes s,
and air enters through the holes t¹, in the tubes t, in the desired amount.
mingled gas and air is ignited at the top of the tubes t, within the cone H, which
constitutes the combustion chamber. The mingling of the gas and air before
ignition, produces, as in the ordinary Bunsen burner almost perfect combustion, and
the additional supply of air inside and outside as in the ordinary argand burner adds
to this effect. The result is a very high degree of heat with but little if any, visible
flame. The platinum basket or cone is at once raised to a high degree of incan-
descense and remains in a highly luminous condition as long as the burner is ignited.
In figure 9, is shown a modification of the form of burner shown in figures 1,
and 7, in which the burner body is composed of two cylindrical shells, having an air
and gas mixing chamber between then. The inner cylinder extends up above the
outer one a certain predetermined distance and a chamber s, is formed therein by
means of a partition or diaphragm as shown. A rod r, extends upwardly from this
partition and upon the top thereof is pivoted the plate h, by means of a socket h¹.
The platinum cylinder H, is attached to the outer edge of this plate h, and extends
downward to the top of the outer cylinder of the burner and is provided with the
band o, which surrounds. the burner as in figures 1, and 7. The chimney holder is

page_text: substantially the same as that shown in figure 1, the band b, being provided with
perforations through which the air passes upwardly within the chimney as shown by
the arrows.
In operation, the gas enters chamber s, and passes into the mixing
chamber through perforations st, and air enters said chamber through perforations t¹.
The mingling of the gas and air in the mixing chamber, produces substantially the
samme result as is produced by the construction shown in figures 1, and 7. The exten-
sion of the inner cylinder as shown, forms an additional support for the plate h, and
confines the heat within a small space adjacent to the platinum cylinder, which is at
once raised to a high degree of incandescense thereby.
The invention is not limited to the use of platinum wire as a substance from which.
to form the cylinder H, as any of the substances known and used for such purposes
may be substituted.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
