Improvements in and relating to Oil Lamp Fittings and for other
Analogous Purposes.
I EDWIN CARPENTER BELLAMY, of 129 Pritchett Street, Birmingham, in the
county of Warwick Manufacturer, do hereby declare the nature of this invention to
be as follows:--
This invention relates to improvements in oil lamps, and oil reservoir fittings, and
its object is to provide an oil tight joint between the body of the burner, and the
metallic mount upon the reservoir, to which it is attached, and also to provide a
similar joint for the screw feed plugs, or charging inlets, to such or other reservoirs.
In making this oil tight joint, for instance for the burners, I first "roll in" the
bottom edge of the metallic mount which is attached to the reservoir for the purpose.
of receiving the burner, or otherwise form a recess upon its inside. Into this recess
is placed a washer of india-rubber, asbestos, cork, or other suitable material.
I then provide upon the bottom of the body of the burner, a stand up edge, which
when the burner is passed into the mount, shall fit or embed itself into such washer,
at the same time that the said burner is being secured either by means of the ordinary
bayonet joint slot or undercut, or when being secured by screwing.
In applying my invention to screw feed plugs, charging inlets, or similar lamp
fittings, I should proceed similarly as described with reference to the burners and
their mounts, that is I provide a recess, cast or spun, to receive the aforesaid washer,
so that the forward end of the screw plug, or the screw cap, as the case may be,
may take and embed itself thereinto, when being screwed up, forming in each case a
perfect oil tight joint.
As will be apparent, this latter part of my invention will not only apply to the
reservoirs of lamps but also to other reservoirs, bottles or cans used for the storage of
the oil.
Dated this 18th day of December 1888

page_text: Analogous Purposes.
I EDWIN CARPENTER BELLAMY of 129 Pritchett Street, Birmingham, in the
county of Warwick Manufacturer 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 improvements in oil lamp, and oil reservoir fittings, and
its object is, to provide an oil tight joint between the body of the burner, and the
metallic mount upon the reservoir to which it is attached, and also to provide a similar
joint for the screw feed plugs, or charging inlets, to such or other reservoirs.
In making this oil tight joint for instance for the burners, I first "roll in" the
bottom edge of the metallic mount which is attached to the reservoir for the purpose
of receiving the burner, or otherwise form a recess upon its inside. Into this recess
is placed a washer of india-rubber, asbestos, cork, or other suitable material.
I then provide upon the bottom of the body of the burner, a stand up edge,
which when the burner is passed into the mount, shall fit or embed itself into such
washer, at the same time that the said burner is being secured either by means of
the ordinary bayonet joint slot or undercut, or when being secured by screwing.
In applying my invention to screw feed plugs, charging inlets, or similar lamp
fittings, 1 should proceed similarly as described with reference to the burners and
their mounts, that is, I provide a recess, to receive the aforesaid washer, so that the
forward end of the screw plug, may take and embed itself thereinto, when being
screwed up, forming in each case a perfect oil tight joint.
As will be apparent, this latter part of my invention will not only apply to the
reservoirs of lamps but also to other reservoirs, bottles or cans, used for the storage
of the oil.
I will now proceed to further explain how this my invention may be performed,
having reference to the accompanying illustrative sheet of drawings, upon which are
figures and letters of reference like letters referring throughout the several views to
the same thing or part, and in which :-
Fig. 1, is a sectional elevation of a lamp burner shewing the projecting rib,
which by pressure into the india rubber &c. washer, forms the oil tight joint.
Fig. 2, is a view of an oil lamp reservoir mount, having the washer attached, for
making the said joint.
Fig. 3, is a sectional view of the burner and the mount when connected.
Fig. 4, is an external view of the burner, and mount.
Fig. 5, illustrates the application of this my invention to the neck of an oil bottle,
or feed screw, of a lamp reservoir &c.
In making this oil tight joint for lamp burners, I first "roll in" the bottom edge a,
of the metallic mount b, which latter is attached to the lamp reservoir, for the purpose
of receiving the burner.

cork or other suitable material to form the joint.
C of india-rubber, asbestos,
I then provide upon the bottom of the body of the burner a stand up edge or
rib d, which, when the burner is passed into the mount b, shall fit or embed itself
into the washer c, as seen in Fig. 3. In many instances these burners are secured to
the mount b, by some projection or projections upon the former, passing under an
extending arm or its equivalent, as seen at e, Fig. 4, the winding spindle f, in this
case being utilized as the projections upon the burner. In such cases the thickness of
the washer c, would be such that the rib d, has to be pressed considerably into it
before the projection can pass under the arm e, &c.
Where the said burners are connected to the mount by means of screw thread the
said screw will of course force the rib d, into the washer."
recess a",
In applying my invention to screw feed plugs, charging inlets &c. I provide a
see Fig. 5, to receive the washer c², so that the extended rib d¹, of the
screw plug h, may take and embed itself thereinto, when being screwed up, thus
forming in each case a perfect oil tight joint.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1st. The improvements in or relating to oil lamp fittings substantially as herein-
described and illustrated upon the drawings in Figs. 1, 2, 3, 4, & 5, that is to say,
rolling in the bottom edge of the reservoir mount or entrance, to form a recess for the
purpose specified.
2nd. The combination of the rolled in recess a, washer c, mount b, with the lamp
burner, having the extended rib d, substantially as hereindescribed and illustrated upon
the drawings in Figs. 1, 2, 3, & 4.
3rd. The modified combination of the rolled in recess a¹, washer c¹, mount b',
with the feed screw plug, having the extended rib d³, substantially as hereindescribed
and illustrated upon the drawings in Fig. 5.
