COMPLETE SPECIFICATION.
Improvements in Central Draft Lamps.
I, CHARLES STANFORD UPTON of 42 Park Place, in the City of New York,
State of New York, U.S.A., Manufacturer, 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 is an improvement in means for elevating the chimney holder or
gallery, of central draft lamps in which the outer wick-tube forms a part of the
burner, and is removable therewith for the purpose of wicking the lamp or adjusting
the wick on the holder, and is fully disclosed in the following Specification of which
the accompanying drawing forms a part, and in which similar letters of reference
indicate like or equivalent parts wherever found throughout the several views.
In said drawings,
Figure 1, represents a central draft lamp provided with my improvements, parts
being shown in section, and other parts being broken away, in order to more fully.
illustrate the application of my improvement to this style of lamp:
Figure 2, is a top plan view, and
Figures 3, and 4, are side elevations of the burner, showing details of construction,
portions of the burner being broken away for this purpose, and the chimney holder
or gallery, being shown in an elevated position.
The chief object of my invention is to provide means for lighting the lamp
without removing the chimney in the class of lamps hereinbefore described, and
particularly in lamps of said class known as overhead or hanging lamps, in which
the removal of the chimney after the shade usually employed is in place, is always
attended with great inconvenience, and danger of breaking the chimney and burning
the hands of the operator.
Referring to the drawing A, represents the lamp reservoir, B, the central draft
tube, and C, D, a removable burner, which in this case consists of two parts, the
lower part C, and the upper adjustable part D, which constitutes the chimney holder
or gallery and is also removable from the other part. The lower part C, is pro-
vided with a tube E, which forms the outer wall of the wick chamber when the
burner is in position, and with an outer perforated air distributor F, by which air is
supplied to the outer mantle of the flame. This lower portion C, of the burner,
consists strictly, as will be seen, of the outer perforated portion referred to, and
the outer wick-tube E, united at the base by a diaphragm G, and the other'
portion F, is provided with, a bead H, which rests upon the top of the neck of the
reservoir when the burner is in position, and with an outwardly projecting flange'
or rim K, on which rests the upper adjustable portion of the burner, the chimney
holder or gallery D. This adjustable portion D, is provided at diametrically
opposite points with downwardly projecting rods L, which are adapted to enter
and slide within guide tubes M, preferably attached to the inner walls of the
perforated portion F, of the lower part of the burner, and the diaphragm G, is
perforated below these tubes, so that the rods L, will pass as shown into the reser-
voir. The rim or flange K, is provided with notches or grooves N, on each side
of the burner, and within these notches or grooves rests a bar O, provided with a
handle O. The rod O, is provided with segmental levers P, firmly attached
thereto, and to each of these levers is hinged or pivoted a link R, and this link is
in turn hinged or pivoted to a downwardly projecting lug or shank S, attached to
the adjustable portion of the burner, D, as shown in Figures 2 and 3; or these
links may be pivoted directly to the rods L, as shown in Fig. 4. A locking
device U, pivoted to the outer wall of the tube E, is provided at its lower end with
an angular outwardly projecting portion U', which, when the bar O, is in position

page_text: and the locking device turned down, rests upon the bar O, and holds it firmly in
place.
In assembling these parts of the burner, the rods L, are first inserted in the
guide tubes M, and the bar O, is then placed in the grooves or notches N, and
the lock U, turned down until the lower outwardly projecting portion U³, rests
firmly upon the bar O, and the upper part D, of the burner, is then pressed
downward until it rests upon the rim or flange K, the levers P, and links R,
by reason of their pivoted connection, readily adjusting themselves to this
movement of the part D. The entire burner is then placed upon the reservoir by
simply inserting the lower part thereof within the neck of the reservoir, where it
is held by an ordinary bayonet joint in the well known way. It is evident, how-
ever, that the lower portion of the burner may be first placed upon the lamp, and
then the upper portion put in position, as hereinbefore described.
In operation, it is only necessary to take hold of the handle O¹, with the thumb
and finger and turn the bar O, when the upper adjustable portion or chimney
holder D, will be elevated to the position shown in Figs. 1, 3 and 4, the levers P,
and the links R, operating to produce this result when the lamp may be lighted or
the wick trimmed as desired, and then by a slight movement of the handle O', in
the opposite direction, the part D, will be lowered to its normal position.
Whenever it becomes necessary to wick the lamp, or to adjust the wick upon the
holder, these parts being of ordinary construction and not shown, the entire burner
including the outer wick tube is lifted from the lamp, when the wickholder and
wick may be readily removed therefrom, and when it is desired to clean the burner
itself or the separate parts thereof, the lock U, is turned out of contact with the
bar O, when the upper part D; of the burner, together with the rods L, bar O,
levers P, &c., may be separated from the lower portion of the burner, and free
access had to all parts 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 removable burner for central draft lamps, consisting of two parts one of
which is adjustable and constitutes the chimney holder, and the other part being
provided with a tube which forms the outer wall of the wick chamber when the
burner is in position, said burner being constructed, and operating, substantially as
shown and described in the foregoing Specification.
2. The combination with a central-draft lamp, of a removable burner consisting
of two parts, one of which is vertically adjustable with reference to the other part
and removable therefrom, the non-adjustable part being provided with a tube
which forms the outer wall of the wick chamber, and with guide tubes, and the
adjustable part being provided with downwardly extending rods which fit movably
within said guide tubes the rods being located within the outer walls of the burner,
devices for raising and lowering the adjustable part and means for connecting said
devices with the non-adjustable part and by operating which the adjustable part
together with the devices for raising and lowering the same may be separated
from the other part, substantially as shown and described.
3. The combination with a central draft-lamp, of a removable burner consisting
of two parts, one of which is vertically adjustable with reference to the other part
and removable therefrom, the non-adjustable part being provided with a tube which
forms the outer wall of the wick-chamber when the burner is in position, and an
upwardly extending portion on which the adjustable part rests, and also with guide-
tubes within the upwardly extending portion, which register with perforations in
the base thereof, and the adjustable part being provided with rods which are
adapted to enter said guide tubes, devices for raising and lowering the adjustable
part and means for connecting said devices with the other part and by operating
which the adjustable part together with the devices for raising or lowering the
same may be separated from the other part, substantially as shown and described.

upwardly extending portion on which the adjustable part rests, and also with guide
tubes within the upwardly extending portion, which register with perforations in
the base thereof, and the adjustable part being provided with rods which are
adapted to enter said guide-tubes, the bar O, provided with levers P, and links R,
