Improvements in Oil Lamps.
We GEORGE WILLIAM PRIDMORE, of Holyhead Road, Handsworth, Staffordshire,
Designer, HERBERT JOSEPH WAKELIN, of 8 Albert Read, Handsworth, Staffordshire,
Assistant Manager of Works, and JAMES JOHNSON, of Stony Lane, Smethwick,
Staffordshire, Manufacturer's Agent do hereby declare the nature of this invention to
be as follows:-
This invention relates primarily, to improvements in what are known as fairy
lights" or illuminating lamps, but which may in part be also applied to night light
lamps, bicycle lamps, and other similar lamps.
Hitherto these "fairy light" lamps have not been constructed in such a manner
as to burn petroleum and other similar oils (except in a congealed condition) and
therefore they are costly in this respect.
In our invention however, we adapt, combine and arrange the parts of this our
lamp, so that we may burn these cheap oils without smoke or smell.
In constructing this our improved lamp, we proceed somewhat thus:-
We provide a shallow oil vessel, having a feed inlet independent of the burner; this
vessel being of metal, glass, or other suitable material.
To this vessel the perforated body of the burner is permanently attached, in the
case of a metal reservoir, by soldering &c., or in the case of a glass &c. vessel, by
mounting it thereto.
Upon the body of the said burner, we provide a combined gallery and dome. This
gallery and dome is preferably fixed to the body of the burner, but may in some cases
if desired be removable therefrom or binged thereto.
Connected to the lower part of the body of the burner, and extending thence to or
near the bottom of the oil vessel, is a tube, having perforations or inlets communicating
with the interior of the said vessel.
Again. We further provide a separate and removable perforated wick tube
(generally round) and of a size that it may freely pass into the aforesaid fixed
perforated tube, so that the oil within the vessel may feed the wick, through such
perforations.
We now provide what may be practically termed an imperishable wick of asbestos,
and of a length suitable to the removable wick tube, and which we now place therein.
This wick is secured in the said wick tube, at a proper height, by means of a pin
passing through the tube and the wick, and thereby retaining it in that position, so
that it cannot be raised or lowered, or, instead of a pin, portions of the side of the
tube may be pressed thereinto, with the same effect.
The difficulty hitherto experienced in lamp burners having no winding mechanism
has been, the trimming and adjustment of the wick to its proper height, but in this
our improved lamp, there will practically need no trimming or other attention to the
said wick, by reason of its imperishable nature, and by its being provided, fixed, and
supplied to users in separate wick tubes, so that when one of such wicks is worn out,
after long use, another combined wick and wick tube may be substituted therefor.
Suitable provision is made in connection with the gallery to receive and secure
the globe, (where a globe or glass is required,) either by combined claws and screws,
or by spring clips, preferably the latter.
By reason of the double perforated wick tubes, and their passing to the bottom of
the oil vessel, all sudden flusbing or outflow of oil through the wick tubes is prevented;
as, should the lamp be overturned the oil can only very slowly indeed find its way
therethrough. Lamps made after this manner, burn for many hours without attention,
and without smell, and are of such a form that they may be conveniently formed into

page_text: groups or cluster lights, for brackets, suspenders, or pillars, for decorative or other
illuminating purposes.
Also the combination of a fixed burner body with the oil vessel, and of a combined
fixed inperishable wick with a removable perforated inner wick tube &c., may be
applied to other similar lamps, such as bicycle lamps, &c.

Improvements in Oil Lamps.
We, GEORGE WILLIAM PRIDMORE, of Holyhead Road, Handsworth, Staffordshire,
Designer, HERBERT JOSEPH WAKELIN, of 8 Albert Road, Handsworth, Staffordshire,
Assistant Manager of Works, and JAMES JOHNSON, of Stony Lane, Smethwick,
Staffordshire, Manufacturer's Agent, 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 primarily, to improvements in what are known as "fairy
lights or illuminating lamps, but which may in part be also applied to night light
lamps, bicycle lamps, and other similar lamps.
Hitherto these fairy lamps have not been constructed in such a manner as to burn
petroleum and other similar oils (except in a congealed condition) and therefore they
are costly in this respect.
In our invention however, we adapt, combine, and arrange the parts of this
our lamp so that we may burn these cheap oils without smoke or smell-as
follows.
In constructing this our improved lamp we proceed somewhat thus:-
:-
We provide a shallow oil vessel, having either a feed inlet independent of the
burner or the supply may if desired be fed through the burner, this vessel being of
metal, glass, or other suitable material.
To this vessel the perforated body of the burner is permanently attached, in the case
of a metal reservoir, by soldering &c., or in the case of a glass &c. vessel, by mounting
it thereto.
.
Upon the body of the said burner, we provide a combined gallery and dome. This
gallery and dome is preferably fixed to the body of the burner, but may in some
cases if desired be removable therefrom.
Connected to the lower part of the body of the burner, and extending thence to or
near the bottom of the oil vessel, is a tube, having perforations or inlets communicating
with the interior of the said vessel.
Again. We further provide a separate and removable perforated wick tube
(generally round) and of a size that it may freely pass into the aforesaid fixed
perforated tube, so that the oil within the vessel may feed the wick, through such
perforations.
We now provide what may be practically termed an imperishable wick of asbestos,
and of a length suitable to the removable wick tube, and which we now place therein.
This wick secured in the said wick tube, at a proper height, by means of a pin
passing through the tube and the wick, and thereby retaining it in that position, so
that it cannot be raised or lowered, or, instead of a pin, portions of the side of the tube
may be pressed thereinto, with the same effect.
The difficulty hitherto experienced in lamp burners having no winding mechanism
has been, the trimming and adjustment of the wick to its proper height, but in this
our improved lamp, there will practically need no trimming or other attention to the
said wick, by reason of its imperishable nature, and by its being provided, fixed, and
supplied to users in separate wick tubes, so that when one of such wicks is worn
out, after long use, another combined wick and wick tube may be substituted
therefor..

page_text: Suitable provision is made in connection with the gallery to receive and secure the
globe, (where a globe or glass is required) either by combined claws and screws, or
by spring clips, preferably the latter.
By reason of the double perforated wick tubes, and their passing to the bottom of
the oil vessel, all sudden flushing or outflow of oil through the wick tubes is pre-
vented; as, should the lamp be overturned the oil can only very slowly find its way
therethrough.
Lamps made after this manner, burn for many hours without attention, and without
smell, and are of such a form that they may be conveniently formed into groups
or cluster lights, for brackets, suspenders, or pillars, for decorative or other illuminating
purposes.
We will now proceed to more particularly explain how this our invention is to be
performed, having reference to the accompanying illustrative sheet of drawings upon
which are figures and letters of reference, similar letters referring throughout the
several views to the same thing or part, and in which:
Fig. 1, is a view in elevation, and Fig. 2, a view in section, of a lamp embracing
generally this our invention.
Fig. 3, is a view in elevation, and Fig. 4, a view in section of a modified form of
lamp embracing also generally this our invention.
Fig. 5, is a view in detail of the gallery, dome, and perforated body secured to
each other and removable from the oil vessel, and Fig. 6, is an inverted view of
Fig. 5.
Figs. 7, 8, 9, 10, 11, 12, 13, & 14, are detail views of the various parts of this our
invention.
In constructing this our improved lamp we proceed somewhat thus:
:-
We provide a shallow oil vessel a, having either a feed inlet b, independent of the
burner, or the supply may if desired be fed through the burner, this vessel being of
metal, glass, or other suitable material.
To this vessel the perforated body c, of the burner is permanently attached, in the
case of a metal reservoir, by soldering &c., or in the case of a glass &c. vessel, by
mounting it thereto.
Upon the body of the said burner, we provide a combined gallery d, and dome e.
This gallery and dome is preferably fixed to the perforated body of the burner as
seen in Figs. 5 & 6, but may in some cases if desired, be removable therefrom,
as seen in Figs. 7 & 8; the perforated body c, of the burner, being attached to the oil
vessel a.
At f, the plate d, forming the gallery, is perforated to permit of the passage of air
to the flame, and it will be observed that this perforated portion is secured to the
said gallery, so as to be permanently combined therewith.
Further, we form the dome e, in the plate & itself, by stamping, so that they also
may be thus permanently combined together. Or in some cases the dome may be
soldered thereto, while the perforations at, are then made in the plate d itself.
Connected to the piece g, is the tube h, which extends from the bottom of the
burner, for some distance towards the bottom of the oil vessel. If this tube. is
carried near to the said bottom, perforations k, are provided, through which the oil
may pass generally however we dispense with these perforations and only carry
the said tube h, for a short distance, as seen in Fig. 2.
Again. We further provide a separate and removable perforated wick tube j,
(generally round) and of a size that it may be readily passed into the aforesaid fixed
perforated tube, but with sufficient tightness to support it therein. The oil within
the vessel thus feeds the wick, through such perforations k.
We now provide what may be practically termed an imperishable wick 1, of
asbestos, and of a length suitable to the removable wick tube j, and which we now
place therein.
The wick, may be secured in the inner tube j, and at the required height for
proper burning, in several ways, as for instance, in Figs. 2, 9, 10, & 11, where the
outer tube h, is made parallel and open throughout, close to the top of the wick

page_text: tubej, is a pin.m, passing across it, and also passing through the wick, and further
overhangs the outside as seen in Figs. 2, & 10. The wick is then cut off close
above the top of the said tube. At n, the tube may also be nipped in, to further (or
of itself) secure the wick therein. Or instead of this pin m, passing through the
tube, it may be secured by soldering &c., across the top of the tube as seen in
Fig. 11. Or in some cases instead of this cross piece being provided upon the tube j,
it may be provided upon the tube h, across the top, as seen at r, in Figs. 4, 12, 13,
& 14, Fig. 13, being a plan view of Fig. 12. In cases shown in Figs. 2, 9, 10, & 11,
the tube i, is passed into the tube h, from the top; while in the case of
Figs. 4, 12, 13, & 14, it is passed upwards from below. In either case the wick is
thereby prevented from being raised too high, and so the size of flame is kept always
the same.
may
By either of these constructions, the wick being permanently attached to the tube j
and fixed therein, no trimming is required beyond the fact that should the upper end
of the wick, by accident or otherwise have been pressed down too much, it
readily be again raised into position by a pin or other small tool; and further, by
these being thus combined in themselves, yet removable from the tube h, a new wick
and tube is readily replaced at any time for an old or damaged one.
The gallery, dome, and glass &c., is firmly held in position to the oil vessel, either
by reason of the central hole in the perforated part of the plate d, being passed
tightly on to the tube h, or, in some cases there may be provided, upon the
underside of the plate d-downhanging legs o, more or less springy, which take into
the interior of the perforated body c, as seen in Fig. 7.
Suitable provision is made in connection with the gallery to receive and secure
the globe p, (where a globe or glass is required,) either by combined claws and
screws, or by spring clips q, preferably the latter.
By reason of the double wick tubes, and their passing into the oil vessel, in the
manner shown, all sudden flushing or outflow of oil through the wick tubes is
prevented; as, should the lamp be overturned, the oil can only very slowly find its
way therethrough.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1st. In an oil lamp, the combination with the oil vessel, of the permanently
attached perforated body, substantially as described and illustrated in Fig. 8:
2nd. In an oil lamp, the combination with the gallery plate d, of the central
perforations, that is, that they are either made in the plate itself, or in a plate
which is permanently attached thereto, substantially as herein described.
3rd. The raising or forming of the dome e, in the plate which forms the gallery,
as described.
4th. The combination of the wick tube j, with the permanently secured wick
substantially as described.
5th. The combination of a removable wick tube j, with an outer tube h, sub-
stantially as described, and illustrated upon the drawings.
6th. The combination with a wick tube, of a cross pin m, or, or their
equivalents, whereby the wick is prevented from being raised too high, substantially
as described and illustrated.
7th. The general combination and arrangement of the parts constituting this
our improved form of lamp, substantially us hereindescribed and illustrated upon
the drawings.
