COMPLETE SPECIFICATION.
Improvements in Lamp Burners.
I CHARLES STANFORD UPTON, of No. 42 Park Place, in the City and County
of New York, and State of New York, United States of America, Manufacturer,
do hereby declare the nature of my invention for "IMPROVEMENTS IN LAMP
BURNERS," 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 lamp-burners, and more particularly to the manner of
constructing the wick-raisers and cones thereof, and is fully disclosed in the
following Specification, of which the accompanying drawing forms a part, wherein
similar numerals of reference designate like or equivalent parts wherever found
throughout the several views, and in which :-
Figure 1, represents a central vertical section of the wick-tube of a lamp and its
attachments, provided with my improved wick-raiser:
Figure 2, represents an end view of the thumb-piece of my improved form of
wick-raiser, and
Figure 3, represents a view in perspective, of a duplex or double-wick burner,
provided with my improvements.
The first part of my invention relates to the wick-raiser. It is usual in lamps,
lamp-stoves and similar devices to provide the wick-raising shaft usually employed,
with a milled wheel or finger button, by which the shaft is operated, and the wick
adjusted. This finger button is attached to the shaft and is constantly becoming
loosened, and sometimes detached from the shaft, whereby it is ren lered useless for
the purpose intended; and the object of this part of my invention is to obviate this
difficulty, and provide a cheap, safe and convenient device for the purposes
mentioned, which will not be subject to the objection specified.
Referring to the drawing: The reference numeral 1, designates the wick-tube,
2, the wick-raiser shaft, 3 the wick-raising ratchet pinions mounted thereon, all of
the usual construction. My improvement consists of a flat-thumb-piece 4, attached
to the end of the wick-raising shaft, by sawing or slotting the end of the shaft in
any desired manner, as shown, and inserting therein the piece 4, and securing the
same in position by soldering, riveting, or in any other way desired.
This piece 4, is preferably in the form of an ogee curve as shown, and is
preferably placed in the slotted shaft, with the ends curved in the direction of the
revolution of the shaft necessary to lower the wick. This shape and position of
the thumb-piece 4, is preferred for the reason that when so made, it is easier to
grasp with the fingers, and they are not so liable to slip therefrom. However I
do not limit myself to any particular form or shape of any part of the device
shown.
The operation of my improved wick-raiser is similar to that of the common form,
upon which it is an improvement, wherein, the thumb-piece 4, being turned by the
fingers the wick in the wick-tube 1, is raised or lowered by the teeth of the ratchet-
wheels 3, catching therein, according as the thumb-piece 4, is turned one way or
the other.
The second part of my invention relates to the cone, and the same is as follows:-
The reference numeral 5, (Fig. 3.) designates the burner cone, and 6, lines of
perforations through the same, arranged adjacent to the edges of the flame slits or
passages thereof, while 7, is a depression or groove formed in that portion of the
cone lying between the two flame-slits.
When in use, a certain proportion of the air, which otherwise would be fed to
the lower part of the flame, by passing through the flame slits or passages, passes
instead through the lines 6, of perforations, and is thus fed to the higher part of

page_text: the flame in a highly heated condition, whereby the steadiness and brilliancy of the
same is much increased; the passage of the air through the two central lines of
perforations in the duplex-burner, being much assisted by reason the air current
striking against the depression 7, in its upward course and being consequently
deflected through the said perforations.
Although I have shown this improved form of cone as applied to a duplex or
double-wick burner, it is evident that such improvement may with but little
modification be applied to single wick-burners, and I do not limit myself to any
particular form of construction thereof.
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. A lamp-burner provided with the wick adjusting device and perforated flame-
cone, constructed and operated substantially as shown and described.
2. A wick-raiser for lamps the shaft of which is provided with a flat thumb-
piece, substantially as shown and described.
3. A wick-raiser for lamps, the rotating-shaft of which is provided with a slot in
which is inserted a thumb-piece bent in the form of an ogee-curve, substantially as
shown and described.
4. A cone for duplex-lamps provided with lines of perforations at each side of
and adjacent to the flame-slits, and a longitudinal depression separating the inner
rows of perforations, substantially as shown and described.
Dated this
day of October 1891.
