page_text: LETTERS PATENT to Albert Rettich of 34 and 35 Gerrard. Street Soho in
the county of Middlesex Lamp Manufacturer for an Invention of AN
IMPROVED BURNER FOR OIL LAMPS communicated to him from abroad by
Messieurs Schwintzer and Gräff persons resident at Berlin in the Empire
of Germany
PROVISIONAL SPECIFICATION left by the said Albert Rettich at the
Office of the Commissioners of Patents on the 19th April 1883.
ALBERT RETTICH of 34 and 35 Gerrard Street Soho in the county of Middlesex
Lamp Manufacturer "AN IMPROVED BURNER FOR OIL LAMPS " A communication
to me from abroad by Messieurs Schwintzer and Gräff persons resident at Berlin
in the Empire of Germany
The object of this invention is an improved burner for oil lamps in which the
flame is composed of or made up by a series of wicks arranged in ring form and
capable of being raised and lowered simultaneously by a turn button through the
intermediation of a pinion and rack this being secured to a perforated holder.
The tubes are attached to a base ring and are so arranged that half round or
segmental strips with pins or studs which support the wicks serve to guide them
up and down the tubes. The tubes are at a distance apart and air is free to pass
through between them to feed the inner channel or central opening of the flame
for supporting combustion.
The tops of the tubes are covered by a ring plate through which the wicks
can pass

ALBERT RETTICH of 34 and 35 Gerrard Street Sobo in the county of Middlesex
A communication to
Lamp Manufacturer AN IMPROVED BURNER FOR OIL LAMPS
me from abroad by Messieurs Schwintzer and Gräff persons resident at Berlin in
the empire of Germany
This invention relates to certain improvements in table and other oil lamps in
or to which a series of cord-cottons are arranged in ring form within tubes for
containing them and in which they can be raised or lowered by rack and pinion
simultaneously said cottons or wicks being held within the tubes by tongued clip
pieces forming an extension of, yet free to slide up and down in the tubes. These
tongue clips carry the wick cords or cottons.
The tubes are encircled by a band at their upper part as to be level with the
tops of the tubes. The tubes are fixed at their lower parts within a socket or
ferrule which carries the pinion for gearing into a rack attached to the tongue
holder to enable it and the tongues and cottons to be raised and lowered.
The outer surface of the ferrules is screw threaded for a collar to fit thereon
the collar serving by claws on its periphery to engage over angled projections
formed on the socket ring attached to the body of the lamp.
The ferrule or socket has pins upon it for the attachment of the gallery or glass
holder in such a manner that it with the glass (chimney or globe) can be removed
without disturbing any other part by one hand to facilitate the trimming or
lighting operation.
The invention is clearly represented in the annexed drawings. Figure 1 is an
elevation and figure 2 a plan. Figure 3 is a section
A, A, are the wick tubes affixed to a partition B at their lower ends and to a
band C at the upper the top edge of the band being level or flush with the topš
of the tubes to give rigidity at that part and a level surface on which all the
wicks can be made to correspond to produce a true circular flame, the wicks (16 or
any other number) according to their thickness and the diameter of the burner.
Below the partition B is a skeleton frame D in whose perforations near the
outer edge the bottom of the cotton carriers or tongues D¹ D¹ are attached. The
frame D has a prong E hinged to it which when turned up limits the height to
which the wicks can be raised so as not to injure the prongs by burning. The
prong may however be turned downwards (such as when new cottons or wicks
have to be put in) to permit of the tongues D, D, being raised and the claws (see
Figure 4) to be exposed above the band C.
F is an air distributor carried by a tubular stem which is surmounted by the
button or flame spreader H. I is the rack and J the pinion on the stem K of the
turn button L by which the raising or lowering of the wicks can be effected.
M, M, are pins or studs projecting from the ferrule or collar N said pin taking
into slots a a for the attachment of the gallery P which supports the chimney Q
and globe R. The gallery P has two curved projections S, S, Figure 5 by which it
can be turned by the hand as at Figure 6 to fit it in position or to remove it as
desired.
T, T, are claws on the edge of the collar U which is screwed on to the ferrule
(lined with cork or other packing to make a tight joint) and arranged to clip over
angled projections V V on the outside of the lamp band W to hold the burner

page_text: and gauery on the body X and from which they can be released and lifted to
permit fresh oil to be poured in.
There are many advantages to be derived from the use of this lamp.
1 The many distinct wicks with the equal division or air passage between them
ensures perfect combustion
2 The flame from each wick licks itself into that of the neighbouring wick and
produces a truly circular flame of equal density
3 The passages through the central distributor coupled with passage of air through
between the tubes and through the gallery to feed the flame at every part
secures the steadiness of flame.
4 The spread effected by the button or spreader so thins the flame as to ensure
clearness of light and maximum of brilliancy.
5 The facility of removing the upper part from the body for filling purposes or
for fitting in new cottons
6 The ease with which the gallery (with chimney and globe) can be lifted from
the burner for trimming purposes and
7 The readiness by which all the wicks can be set to the same level.
Having now described the nature of the said invention and in what manner
the same is to be performed I declare that I claim
First The special construction and arrangement of the various parts of a table
lamp as hereinbefore described and substantially as shown in the annexed
drawings
Secondly The claw and projection fastenings as a combination by which the
burner and gallery can be removed bodily or the gallery only for the
purpose or purposes set forth when forming part of a many cord-cotton
wicked lamp as set forth.
Thirdly The band C at the upper end of fixed tubes A A (of a many cord-cotton
wicked burner) and level therewith as and for the purposes described and
substantially as shown in the annexed drawings.
In witness whereof I the said Albert Rettich have hereunto set my hand and
seal this seventeenth day of October in the year of our Lord One thousand
eight hundred and eighty three
