Improvements in mechanism for Raising the and mys
and Domes of Oil Lamps for Trimming, Filling, and Lighting.
I FRANCIS ROBERT BAKER of Snow Hill, Birmingham in the county of Warwick
Engineer do hereby declare the nature of this invention to be as follows:-
This invention relates to the raising of the globe, chimney and dome of oil lamps,
to facilitate the filling or trimming lighting &c. of such lamps; and has for its object
the raising of such parts by a direct slide lifting action after the following manner :-
I make the dome and gallery, separate from the body of the burner, the said
gallery being preferably made double; one being attached to the dome and lying
within the second which is fixed, and attached as ordinarily to the body of the burner.
Attached to, and extending downwards from the dome and gallery, through the cone
and lower end or screw of the body, I provide two slide rods, one upon either side,
the holes in the body of the burner through which they pass, forming the guides for
such rods sliding up and down. In connection with one of these rods I further
provide a tube, its inner diameter for a certain distance forming a guide wherein the
rod may work, the lower end of the said tube working in the hole in the lower part
of the body of the burner in place of the rod. At a suitable point in the tube a
stop piece would be placed, so that upon lifting the tube, the bottom of the rod would
rest thereupon, and then the rod itself &c. would be lifted.
From the side of this tube a thumb bracket is carried to the exterior part of
the body, so that it may be manipulated by the thumb and finger. A vertical slot
would be provided in the side of the body to allow of the upward and downward
motion of the bracket or arm.
Thus when the bracket is lifted up to the fixed gallery by means of the thumb and
finger, the inner gallery would also be raised to the same extent, carrying with it the
globe, chimney and dome &c. clear of the wick tubes, giving clear access to such parts
for trimming, filling, &c.
Having lifted it thus, I further provide for its retention in such position, by means
of a swinging catch or its equivalent, which hangs from below the fixed gallery, and

page_text: when the bracket or arm is lifted to that point, the said catch is pushed back, until
the bracket has passed its projection, when such projection or catch passes under the
bracket and holds it up. Upon again pushing by hand the said catch from the arm,
the arm &c., may be lowered into position.

and Domes of Oil Lamps for Trimming, Filling, and Lighting.
I FRANCIS ROBERT BAKER, of Snow Hill, Birmingham in the county of Warwick
Engineer, 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 the raising of the globe, chimney, gallery and dome of oil
lamps, to facilitate the trimming, lighting &c. of such lamps, and has for its object,
the, raising of such parts by a direct slide lifting action, after the following manner :-
I make the dome and moving gallery separate from the body of the burner. The
said gallery may be made double, the one attached to the dome, and lying within the
second or outer one, which would be fixed and attached as ordinarily to the body of
the burner, its rim or outer flange extending beyond the first or inner one, so that the
thumb may rest thereon when operating the lifter.
As however the forming of this fixed outer gallery in its entire circle would be
more for artistic purposes than for use; I provide generally, but a portion of it,
immediately above the lifting machanism hereinafter explained.
Attached to, and extending downwards from the dome and gallery, through the
cone or cap, and lower end or screw of the body, I provide two slide rods, one upon
either side; the holes in the body of the burner, through which they pass forming
the guide for such rods sliding up and down.
"

page_text: In connection with one of these rods I further provide a tube, its inner diameter
for a certain distance forming a guide wherein the rod may work, the lower end of
the said tube, working in the hole in the lower part of the body of the burner, in
place of the rod. At a suitable point of the tube, a stop piece would be provided, so
that upon lifting the tube, the rod itself &c., would be also lifted.
From the side of this tube, a bracket is carried to the exterior part of the body, so
that it may be manipulated by the finger. A vertical slot would be provided in the
side of the body, to allow of the upward and downward motion of the bracket or arm.
Thus when the bracket is lifted up to the fixed projection (gallery) by means of the
thumb and finger, the gallery would also be raised to the same extent, carrying with
it the globe, chimney, dome &c., clear of the wick tubes, giving clear access to such
parts for trimming, lighting &c.
Having lifted it thus, I further provide for its retention in such position, by means
of a swinging catch, or its equivalent, which swings or rocks below the fixed
gallery, and when the bracket or arm is lifted to that point, the said catch is pushed
back, until the bracket has passed its projection, when such projection or catch passes
under the bracket, and holds it up. Upon again pushing by hand the said catch from
the arm, the arm &c. may be lowered into position.
I will now proceed to more particularly describe with reference to the accom-
panying drawings the manner in which my invention is to be performed. Upon the
said drawings there are figures and letters of reference, similar letters referring
throughout the several views to the same thing or part.
Fig. is a sectional view of a burner with raising mechanism constructed
according to my invention.
Fig. 2 is a complete side elevation of Fig. 1.
Fig. 3 is a plan of the burner and lifting arrangement, with the gallery chimney
holder &c. removed.
Fig. 4 is a sectional elevation, similar to Fig. 1, but shewing the gallery &c. in its
raised position.
Fig. 5 is a side, and front elevation and plan, in detail, of the lifter or bracket and
slide.
Fig. 6 is an inverted plan in detail of the bottom of the burner, shewing the
relative position of the slides to the wick tubes.
a is the body of the burner, b is the cone or cap, c is the gallery, d is the dome, and
e is the chimney holder; ff are the wick tubes, g, gl are the wick winders, h is that
portion of the burner which fits into the neck of the oil reservoir, (not shewn) and
which may be secured to such reservoir by any ordinary method, such as by screwing,
or by bayonet fastening. I make the gallery c, the dome d and the chimney holder e,
separate form the body of the burner.
To the underside of the gallery I attach two slide rods i, i¹, and to accomodate
these rods I further provide tubular guides, in the lower part of the body of the
burner. In connection with the sliding rod i, I provide a sliding tube k, see
Figs. 1, 3, 4, 5 & 6. The inside of this tube k, furnishes the guide for the rod i to
work in when the entire removal of the gallery &c. is needed, its external surface
sliding in the tubular guide . At a suitable point in the tube k, say at 1, a stop
piere may be placed, so that when the tube is lifted, the rod itself would be lifted, and
with it, of course that to which it was attached, viz., the gallery &c. Instead of
forming the stop piece underneath the rod, however, I prefer to arrange it as
illustrated; that is, to form the stop at the upper end of the tube k, by carrying the
said tube upwards until it comes against the bracket m carrying the rod i.
Again, from the side of the tube k I extend a bracket n having a finger lift piece o
formed thereon.
As already intimated in preference to making a double gallery all round, I prefer
only to use a portion of it or projection p, which serves to resist the upward lifting
action upon the lamp when the gallery is being raised. A slot q is formed in the side
of the body of the burner in which the bracket or arm n may work.
Thus it will be readily seen from Fig. 1, that upon placing the thumb upon the

page_text: and
fixed piece p, the fore finger under the bracket n, and closing the thumb and finger
together, the gallery &c. would be lifted similar as shewn in Fig. 4, the rod i¹,
the tube k, sliding respectively in the guider j¹ & j.
Upon again referring to Fig. 1, it will be seen that at "", I form a joint upon which
works a tilting catch 8. This lever catch is carried sufficiently high at t, and there
formed or bent to serve as a support for the peg u, in order to retain the gallery &c.
in its raised position.
As will be seen this pegu is attached to the arm n at a point immediately in
vertical line with the surface t, so that when the arm n is lifted the peg u, comes in
contact with the front inclined surface of the catch lever 8, when the said catch is
gently pushed back until the peg has passed, when by reason of its overhanging
weight, the catch assumes its normal position, bringing the surface t beneath the
peg u, and thus supporting it as seen in Fig. 4.
Upon again placing the fore finger underneath the arm n, the fore part of the said
finger may at the same time raise the front end v, of the catch s, until the surface t is
beyond or free of the line of descent of the peg u, when the gallery &c. may be
lowered into its working or normal position.
When it is desired that the gallery &c. should be entirely removed, these parts as
will be seen may be readily drawn clear of the tube k, and guide j, in which the
rods & slide.
I wish it to be understood that I do not claim the carrying of the gallery &c. upon
the two slides i & as being new, as I am aware that such parts and method are
old, but, 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 :-
1st. The combination of the extended arm n, and tubular guide or slide k, with the
fixed projecting thumb piece p, constructed and arranged substantially as herein-
described and illustrated, and for the purposes set forth.
2nd. The catch or supports, acting in association with the peg u, for holding the
gallery in its raised position, constructed and arranged substantially as illustrated and
described.
