Improvements in Lamp Burners.
I, ISAAC FRANKLING STERLING, a Citizen of the United States of America,
residing at Texarkana, in the County of Bowie, State of Texas, U.S.A., Medical
Doctor, do hereby declare the nature of my 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 that portion of a lamp called the burner and its object
is to provide means whereby the wick-tube may be parted longitudinally or
vertically to permit the wick being laid in at its open side; means to keep the wick
in place until the tube is closed upon it and at the same time to avoid weakening
the tube materially and to guard against leakage along the joint of the tube.
To this end my invention consists in the construction and combination of parts
forming a "lamp burner" hereinafter described and claimed reference being had to
the accompanying drawings, in which:
Figure 1 is a top view of a lamp burner parted according to my invention with
the cap turned over to one side.
Figure 2 is an inner face view of one side of the same, and
Figure 3 is a horizontal section at line a showing a modification thereof.
No. 5 represents the body of the burner in which the spur feed-wheel 6 is
journalled, and vertically through which the wick-tube 7 is firmly secured. 8 is the
base-plate on which the chimney is to be supported and 9 is the common cap
hinged to the base-plate and perforated to permit the blaze to rise from the wick.
I make the tube with an opening 10 at one vertical side, into which the wick
may be inserted one edge at a time under the side edges or flanges 11 of the tube.
The base-plate is parted across a little to one side of center to retain the body 7 of
the tube in the larger portion, and the cap to cover the said opening in the smaller
portion. The said cap preferably consists of the usual vent tube 12 which is enough
wider than the opening to cover it and lap over the edges of the flanges 11 a little
to prevent leakage, but the cap may be a plain strip of metal in case it should be
desirable to make the opening in that side of the tube which holds the feed-
wheel 6.
The base-plate is hinged at one edge 13 to swing open, and is provided with a
spring hasp 14 at the other edge which holds the parts closed until the burner is
screwed into the lamp collar then the body is firmly held by the said collar. There
would be the advantage in parting the tube on the side shown in Figure 3 that the
spur-wheel would be out of the way while inserting the wick and would naturally
penetrate the wick easily on being closed but I think this would be more than
balanced by the cost of the extra cap piece and I prefer the style shown in the
other figures.
If the tube were parted centrally at its two edges the uncovered seams thereat
would be likely to leak and the two portions of the tube without my side flanges
would be very weak, the fuzzy edges of the wick would be likely to become caught
at either edge when closing the hinged joint, thus rendering it very difficult to
make use of a tube so parted, and I do not elect a tube parted centrally as my
invention.
Having thus 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 as my invention is :
1. The combination in a lamp burner of a base-plate and body parted across at
one side of contra and hinged at one adore of the plate the tube having an opening

page_text: in one vertical side with flanges forming a portion of that side at the edges of the
opening, and being secured to one portion of the said plate and body, and a cap
secured to the other portion of the plate and body and adapted to cover the said
opening and to lap a little upon the flanged edges thereof when closed substantially
as set forth.
2. The combination in a lamp burner of a base-plate and body each formed in
two parts hinged at one edge of the former; a wick tube having an opening in one
vertical side and flanged edges extending thereto; and a cap consisting of a vent
tube adapted to cover the said opening, substantially as described.
Dated this 8th day of June 1891.
