Improvements in Lamp Burners.
I, WALTER EUGENE MAYO, of 34 Wabash Avenue, Chicago, in the County
of Cook, and State of Illinois, United States of America, Gentleman, 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 relates to an improvement in lamp buruers, and has for its object
to simplify and improve the construction of such burners and provide novel means
whereby an abundant supply of fresh air is admitted beneath the lower annular
edge of the chimney for the purpose of producing a larger and more brilliant flame
and a brighter and more satisfactory light. A further object of the invention is
to provide the burner with a novel form of standard or spring, by means of which
chimneys of different sizes may be accommodated and held in place thereupon. In
order to accomplish the objects above mentioned, the invention consists in certain
novel features and details of constructions and arrangement of parts, as hereinafter
particularly described, illustrated in the drawings and finally embodied in the
claims.
In the accompanying drawings:
Fig. 1 is a perspective view of a lamp burner constructed in accordance with
this invention with the flame cap or cone thrown back on its hinge.
Fig. 2 is a plan view of the same.
Fig. 3 is a side elevation of the device showing the form of the standards or
springs for retaining chimneys of different sizes in place, different sizes of chimneys
being indicated in dotted lines.
Fig. 4 is a vertical section taken through the lamp burner.
Similar numerals of reference designate corresponding parts in the several figures
of the drawings.
Referring to the accompanying drawings, a lamp burner is illustrated therein,
which comprises in its construction the several elements found in the ordinary
construction of articles of this nature. 1 designates the usual flame cone or cap,
which is hinged to the base of the burner and provided with the usual flame
orifice 2. It will, of course, be understood that the burner is provided with the
usual body portion 3, which is screw threaded and adapted to be threaded into a
socket of corresponding size in the lamp. The upper portion of the body of the
burner is expanded or provided with a surrounding annular ledge 4 which is
perforated at numerous points, as indicated at 5, to allow the admission of air to
the center of the burner 6 indicates a perforate sheet metal top which is applied
to the body of the burner and is of a size corresponding to the diameter of the base
of the cap or cone 1, and immediately underlying the same. In this manner, fresh air
is admitted to the interior of said cone in a manner which is well understood in the
art to which this invention appertains. The burner is also provided with the usual
wick duct or passage 7 and with a rotary wick feed 8, all of which is of the usual
construction.
The invention, herein contemplated, consists in mounting rigidly upon the body
of the burner, above described, or of any similar form of burner, a conical lamp
chimney support, which is annular in form and extends entirely around the body of
the burner. This conical support is preferably made from thin sheet metal which
is crimped or fluted radially, as indicated at 9. These corrugations or crimps

page_text: extend entirely around the conical chimney support and serve to admit fresh air
directly into the lamp chimney and between said chimney and the flame cone as
will be apparent upon an inspection of Fig. 3. The effect of the admission of fresh
air at such a point or series of points is to produce perfect combustion within the
chimney and thus obtain a larger and clearer light. By forming the corrugations
as described in the chimney support and by making the same in conical form or
with an inclined upper face, it will he apparent that such support and the
corrugations therein may be readily and easily kept clean and free from such
matter as has a tendency to accumulate around the base of the chimney, thus
providing for a constant supply of fresh air to the flame. The invention also
contemplates providing such corrugated support with a series of standards or
springs 10 of peculiar form whereby they are adapted to retain in place chimneys
of different sizes. Each standard or spring 10 is formed preferably from thin
brass or sheet metal, or it may be formed from spring wire and is secured at its
lower end to said corrugated support by solder or in any usual or preferred
The spring or standard 10 is provided at its upper end with a scroll or
loop 11 for facilitating the application of the chimney and between such scroll and
the corrugated support, said standard or spring is provided with inwardly and
outwardly bent portions 12. The standards or springs 10 and the outwardly
and inwardly extending portions thereof are disposed in such manner that for
instance, a number 1 chimney may be placed upon the corrugated support and
confined between and within said standards or springs, and a number 2 chimney be
placed upon said corrugated support in such manner as to surround said standards
or springs, in which case the latter will press outwardly against the inner face of
the chimney and thereby retain the same in place. In this way, it will be seen
that different sizes of chimneys may be used to equal advantage. It is to be
understood of course, that the advantage resulting from the use of standards or
springs of the forin described resides in the fact that where, for instance, a small
chimney becomes broken and another chimney of the same size is not at hand,
then, and in that case, a larger chimney may be employed with equal facility.
manner.
The device described is very simple in construction, the particular form of
corrugated conical chimney support is capable of being very easily and quickly
cleaned and kept free from obstruction, a brighter and more satisfactory light is
produced as a result, and the burner is capable of receiving chimneys of different
sizes.
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 I claim is
1. The combination with the body of a lamp burner, of a conical lamp chimney
support made of imperforate sheet metal and formed with radial declining
corrugations for admitting air beneath the base of the chimney, and also formed
with a central opening closed by perforate sheet metal, and a flame cone fitting
over said perforate sheet metal center and arranged to leave a surrounding air
space between the cone and chimney, substantially as and for the purpose
specified.
2. In a lamp burner, the combination with the chimney support, of a series of
standards or springs provided with inwardly and outwardly disposed convolutions
or recurved portions, said standards or springs and the convoluted portions thereof
being disposed in such manner as to accommodate and retain in place chimneys of
different standard or market sizes, substantially as specified.
