1, ALFRED JOHNSON ASPINALL, of 19 Edge Vale, Smithdown Road, Liverpool, in
the County of Lancaster do hereby declare the nature of my said invention to
be as follows:-
According to my Invention there is provided a mouth piece, or feeding guard to the
"collar" of oil, or spirit lamps. By the "collar" I mean that part through which
the lamp is filled and into which the burner fits. This mouth piece, or feeding guard
may form part of the "collar," or it may be a separate part fitting into the "collar."
I also provide that part of the burner which fits, or screws into the "collar" with
holes, which holes are so placed that when the burner is partly unscrewed, or raised,
the holes are exposed and oil, or spirit poured into the mouth piece, or feeding guard,
will pass through the holes into the lamp and when the lamp is charged and the
burner screwed, or forced down again the holes are closed. Instead of using the
holes in the burner to feed through, the burner may be lifted out of the "collar," so
that the oil, or spirit will on being poured into the mouth piece, or feeding guard run
over the lip of the collar into the lamp.
By constructing lamps with a feeding guard as above set forth the lamp can be fed
without danger of the oil, or spirit running over when filling the lamp, and the guard
takes the drippings from the wick when filling. If the lamp be overfilled the surplus
will come into the guard instead of running over the lamp. Any oil thrown off from
the wick while burning is caught in the guard.

page_text: 1, ALFRED JOHNSON ASPINALL, of 19 Edge Vale, Smithdown Road, Liverpool, in
the County of Lancaster, do hereby declare the nature of my said invention and in
what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
According to my invention there is provided a mouth piece, or feeding guard to the
"collar of oil or spirit lamps. By the "collar" I mean that part through which
the lamp is filled and into which the burner fits. This mouth piece, or feeding guard,
may form part of the collar, or it may be a separate part fitting into the collar.
I also provide that part of the burner which fits or screws into the collar with
holes which holes are so placed that when the burner is partly unscrewed, or raised,
the holes are exposed and oil or spirit poured into the mouth piece or feeding guard
will pass through the holes into the lamp, and when the lamp is charged and the
burner screwed, or forced down again the holes are sealed. Instead of using the
holes in the burner to feed through, the burner may be lifted out of the collar, so
that the oil or spirit will on being poured into the mouth piece, or feeding guard
run over the lip of the collar into the lamp.
By constructing lamps with a feeding guard as above set forth the lamp can be
fed without danger of the oil, or spirit running over when filling the lamp and the
guard takes the drippings from the wick when filling. If the lamp be overfilled the
surplus will come into the guard instead of running over the lamp. Any oil thrown
off from the wick while burning is caught in the guard.
In the drawings which serve to illustrate my invention, Figure 1 is an elevation
of burner of a lamp provided with my improvements, and Figure 2 is a plan of same
at the line XX Figure 1.
Figure 3 shows in elevation a modified form of my invention; Figure 4 is a detail
of the feeding guard thereof in sectional elevation, and Figure 5 is a plan of same.
Figure 6 shows my invention applied to a lamp wherein the burner fits into the
collar of the lamp in lieu of screwing into it, and Figure 7 shows it turned 90° about
its vertical axis.
The same figures and letters of reference are used to denote like or corresponding
parts throughout the views.
With reference in the first instance to. Figures and 2, a designates the feeding
guard, the metal collar, c the neck of the oil receptacle of the lamp, d the burner of
the lamp, and the portion of said burner which screws into the collar. In this
instance the feeding guard a is attached to, or forms part of the collar c. To fill the
lamp the burner is unscrewed from the collar e and the oil is poured into the feeding
guard a.
In Figures 3, 4 and 5 the feeding guard a is made as a separate thing, having a
screwed shank a¹ above and below; the lower portion of which screws into the collar b,
the burner screwing into the upper portion. In this instance holes a² may be

page_text: formed in the upper portion of the shank a' by which means the oil can be supplied to
the oil receptacle by screwing the burner d out of the shank a¹ until its lower edge is
above the lower portion of the holes a². The guard a in this case, it will be seen can
be made to suit and be applicable to existing lamps, or lamps made in the existing
methods or forms.
Figures 6 and 7 illustrate that part of my invention in which the burner fits into
and is so attached to the collar of the lamp, in lieu of screwing therein, as in Figures 1
to 5. In this instance the portion consists of a tubular stem made of such a
length-as is also that portion of the collar -to form the requisite steadiness of con-
nection. To lock the portion d with the collar 6 I provide a groove or slot d² in the
portion d, and a projection on the collar to slide in such groove. When the
portion is pressed quite down the burner is turned a partial revolution and thereby
becomes locked in the collar. This connection it will be readily seen is the well
known bayonet joint. In order to allow the lamp to be supplied with oil without
taking the burner completely out of its collar I form an aperture a² in the portion d',
through which the oil is poured when raised above the hollow of the guard a.
burner and collar herein described are of the well known metallic form, the guard a
is also preferably made of thin sheet brass such as is generally employed in this kind
of lamp work, but of course it may be made of any suitable material.
The
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. The combination with the collar or neck of an oil or spirit lamp of the kind
herein specified, or the burner thereof, of a feeding guard for the purpose set forth.
2. As a new or improved article of manufacture, a feeding guard for lamps, as or
substantially as set forth.
3. The combination of the collar band feeding guard a, substantially as set forth
with reference to Figures 1 and 2 of the drawings.
4. The feeding guard a provided with an upper and lower screwed shank a', sub-
stantially as set forth with reference to Figures 3, 4 and 5 of the drawings.
5. The combination with a burner of a lamp of the kind herein described, of a
tubular stem adapted to fit in the collar of said lamp, substantially as set forth.
6. The combination with the collar of a lamp of the kind herein described of a
feeding guard a, burner d, and tubular stem d set forth with reference to Figures 6
and 7 of the drawings.
