I FRANK RHIND of No. 258, Seventeenth Street, Brooklyn in the State of New
York, United States of America, Salesman do hereby declare the nature of this
invention to be as follows:-
My invention consists of the combination in a lamp of a central air tube, a reservoir
composed of an open bottom glass vessel and a metallic septum connected to the air
tube, and forming the bottom and having metallic rims at each side of the lower edge
of the glass vessel, and cement that is proof against the action of kerosene filling the
groove between the rims and securing the glass; and I provide stays that extend
from the lower end of the air tube to the inner part of a metal base for securely
holding the air tube in its central position.
The base of the lamp is of sheet metal stamped up to the desired ornamental shape
and hollow, and it terminates at the upper end in a rim, and within the base and
below said rim is a septum through which the air tube passes and is secured by
solder;
the edges of the septum are also secured by solder around the base of
said rim. The lower end of the air tube is stayed by a disk or braces that extend to
the interior of the lamp base.
Upon the septum there is a rim leaving a space between the same and the rim upon
the base, sufficient for the reception of the lower end of the glass reservoir and the
cement by which the same is fastened into place.
The cement which I make use of and which I find is proof against the action of
kerosene and adheres firmly to both the glass and the metal and consolidates into a
very hard and strong mass, is composed of litharge and glycerine, worked up to a
stiff paste.
The top of the lamp reservoir is made of sheet metal with a rim, within which the

page_text: upper edge of the glass reservoir is received, and in this top there is a screw neck and
plug that is removable for filling.
By making use of a septum between the cemented joint and the air tube, there is
no risk of the cement being unduly strained or cracked by the expansion or heat of
the lamp, and the air tube is held in a central position to the other parts of the lamp,
or can be adjusted if necessary after the reservoir is cemented in place, because the
septum will yield slightly without injury to the cement, and the stays securely hold
the air tube in its central position when adjusted.
The sheet metal base may have feet or other support formed in one with said base
or said base may be secured to a cast metal support.

page_text: I, FRANK RHIND of No. 258 Seventeenth Street, Brooklyn, in the State of New
York, United States of America, Salesman do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:—
My invention consists of the combination in a lamp, of a central air tube, a
reservoir composed of an open bottom glass vessel and a metallic septum connected to
the air tube, and forming the bottom and having metallic rims at each side of the
lower edge of the glass vessel, and cement that is proof against the action of kerosene
filling the groove between the rims and securing the glass; and I provide stays that
extend from the lower end of the air tube to the inner part of a metal base for securely
holding the air tube in its central position.
In the drawing.
Fig. 1. is a vertical section of the lamp reservoir and base and
Fig. 2. is a horizontal plan at the line..
The base A. of the lamp is of sheet metal stamped up to the desired ornamental
shape and hollow, and it terminates at the upper end in a rim B. and within the base
and below the rim B. is a septum . through which the air tube D. passes and is
secured by solder; the edges of the septum are also secured by solder around the base
of the rim B.
The lower end of the air tube D. is stayed by the disk or braces E. that extend to
the interior of the lamp base A.
Upon the septum C. there is a rim F leaving a space between the same and the
rin B. sufficient for the reception of the lower end of the glass reservoir H. and the
cement, by which the same is fastened into place.
The cement which I make use of and which I find is proof against the action of
kerosene and adheres firmly to both the glass and the metal and consolidates into a
very hard and strong mass, is composed of litharge and glycerine worked up to a stiff
paste.
The top K, of the lamp reservoir is made of sheet metal with a rim I. within which
the upper edge of the glass reservoir is received, and in this top K. there is a screw
neck and plug M. that is removable for filling.
By making use of a septum between the cemented joint and the air-tube, there is
no risk of the cement being unduly strained or cracked by the expansion or heat of
the lamp, and the air tube is held in a central position to the other parts of the lamp,
or can be adjusted if necessary after the reservoir is cemented in place, because the
septum will yield slightly without injury to the cement and the stays E. securely hold
the air tube in its central position when adjusted.
The sheet metal base A. may have feet or other support formed in one with said

page_text: base A. or said base A. may be secured to a cast metal support A' as shown in Fig. 1.
Or the base A may be otherwise formed and for instance to suit a hanging lamp.
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
First. The combination with the central air tube, of a reservoir composed of an
open bottomed glass vessel, and a metallic septum connected to the air tube and
forming the bottom and having. metallic rims at each side of the lower edge of the
glass vessel and cement that is proof against the action of kerosene filling the groove
Between the rims and securing the glass, substantially as set forth.
Second. The combination with a glass reservoir, of a metal base having a rin
within which the glass reservoir is secured by cement that is proof against the action
of kerosene, a septum within the base, an air tube passing through the septum and
soldered to the same, and stays extending from the lower end of the air tube to the
inner part of the base, substantially as set forth.
