COMPLETE SPECIFICATION.
Improvements in Oil Lamps and Stoves.
I BARUCH CARS of the Lion Lamp Works, Charlotte Street, Great Eastern Street,
in the County of Middlesex, Lamp Manufacturer, (partly my own invention and
partly the result of a communication to me by Budweg and Sohn of 26 Schmid
Strasse Berlin in the Empire of Germany Manufacturers) 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:-
My invention relates principally to that class of lamps in which a round wick is
enclosed between two concentric imperforate tubes the inner one of which passes
through the oil container or reservoir and conveys a supply of air to the centre
of the flame, and the outer one of which is a fixture to the burner and descends
nearly to the bottom of the oil container and serves
dangerously sudden flow thereof to the flame in the event of the lamp being over-
trap the oil or prevent a
turned.
In this class of lamp great difficulty is experienced in inserting the wick in
position and when the lamp is burning in consequence of the wick being tightly
ênclosed for nearly its entire length between two plain surfaces the requisite supply
of oil to the flame is much obstructed.
Now according to my invention I obviate these defects and I also provide an
efficient wick carrier by means of which a round or flat wick but more especially
a round wick may be equally acted upon all round its circumference by the wick
raiser.
For this purpose I dispense with the fixed outer descending tube which forms
the oil trap and I employ in lien thereof a loose or detached tube which is corru-
gated or fluted preferably in the form of a spiral or
required length to act as a trap to the oil.
screw thread and is of the
This tube encircles the wick and forms the carrier and in consequence of its being
loose or detached it is, quite easy to pass it over the wick and then to introduce it
together with the wick into its place in the lamp.
This carrier is encircled by a collar or cylinder or hand whose outer circumference
fits closely the burner-fitting or an extension thereof with capability of rising and
falling oil-tight therein and if necessary a suitable recess or slot is formed in the
collar or cylinder to permit the pinion of the wick-raiser to engage the flutings or
corrugations of the wick carrier.
The interior of the wick carrier at its upper part is formed with a plain band or
collar to closely fit the wick.
When the corrugations or flutings of the wick-carrier are of the form of a spiral
or screw I may if desired impart the necessary vertical movements to the wick
carrier by means of a horizontally rotating wick raiser so formed as to engage the
corrugations or flutings thereof.
In this case I provide the wick carrier with a projecting stud engaging a downwardly
projecting guide carried by the burner-fitting so as to prevent the rotation of the
wick carrier but at the same time to permit of the necessary vertical movement
thereof; or other suitable means may be employed to attain this end.

page_text: .
The wick-carrier being made of suitable length to descend the required distance
into the container acts as an efficient trap to the oil whilst at the same time the ways
or passages formed by the spiral corrugations or flutings ensure a full and proper
supply of oil to nearly the entire length of the wick and consequently to the flame.
In applying my invention to lamps fitted with burners arranged for a single flat
wick the central air tube is dispensed with and the form and construction of the wick
carrier and co-acting parts are necessarily somewhat modified.
In some cases in lieu of forming the corrugations or flutings spirally around the
wick carrier they may take the form of annular rings or ribs but this construction
would be more especially applicable to lamps where the oil trap is not required and a
short wick carrier is consequently employed.
My improvements are also applicable to oil stoves.
And in order that the said invention may be more clearly understood and readily
carried into effect. I will proceed aided by the accompanying drawings more fully to
describe the same.

In the several figures of the drawings like parts are indicated by similar letters of
reference.
Referring to Figures 1, 2 and 3,
a represents the oil container or reservoir which is formed with a central tube or
way a therethrough as heretofore in order to convey a supply of air to the centre of
the flame and represents the wick which is passed over and fits closely the air
supply tube a and c represents a loose or detached imperforate tube which is corru-
gated or fluted preferably in the form of a spiral or screw thread c¹ as shewn and is
of the required length to act as a trap to the oil in the container or reservoir
fixed descending tube hitherto employed for that purpose being dispensed with.
the
The tube c encircles the wick and in consequence of its being loose or detached it is
quite easy when the burner d is removed from its fitting a² to pass it over the wick b,
then to pass it together with the wick b over the air tube a¹ in the act of returning the
burner à to its place in the lamp.
The tube c by reason of its peculiar formation constitutes an efficient wick carrier
as it obtains a very firm grip of the wick and enables the same to be equally acted
upon all round its circumference by the wick raiser d'.
The tube or wick carrier c is encircled by a collar cylinder or band c² which is fixed
thereto and fits closely an extension a³ of the burner-fitting a² with capability of

page_text: rising and falling oil-tight therein ind if necessary when employing a broad collar or
band such collar or land may be formed with a slot or recess (not shown) open at
its upper part but closed at its lower part in order to permit the pinion of the wick
raiser to engage the flutings, or corrugations of the wick carrier e which would
otherwise be covered by the collar or band c² and thus give the wick carrier ea greater
range of adjustment.
:
The tube or wick carrier c at its upper part is formed or provided with a plain band
or collar which, fits closely the wick in order to prevent the oil flowing out at that
point-in the event of the lamp being overturned.
By these means I am enabled more readily to insert the wick b in position in the
lamp than heretofore and in consequence of the wick carrier c being made of suitable
length to descend the required distance into the oil container a I obtain an efficient
trap to the oil whilst at the same time the ways or passages formed by the spiral
corrugations or fluting c¹ of the wick carrier c ensure a full and proper supply of
oil to nearly the entire length of the wick and consequently to the flame.
In the modification represented at Figure 4 the extension a³ of the burner fitting a
is dispensed with and the outer wall d³ of the wick tube is formed at its lower part
with a similar extension a³ for the same purpose.
In the arrangement represented at Figures 5, 6 and 7 the ordinary pinion wick
raiser is dispensed with and advantage is taken of the flutings or corrugations c¹ of
the wick carrier c being of the form of a spiral or screw to impart the necessary
vertical movements to the wick carrier c by means of a horizontally rotating wick
raiser d.
The horizonial wick raises d' is formed like a nut with a screw thread d² which
engages the screw like corrugations or flutings c¹ of the wick carrier c and straps or
ties are employed to connect the upper and lower parts of the burner frame and
thus prevent the upper part rotating with the wick raiser d¹.
In order to prevent the rotation of the wick carrier c with the wick raiser d¹ but at
the same time permit of the necessary vertical movement thereof, 1 provide the wick
carrier with a projecting stud or pin c which engages a grooved guide a carried by
the downward extension a³ of the burner fitting a².
In the modification represented at Figure 8 I have shown the converse of this
arrangement, that is to say a groove c is formed in the collar or band 2 of the wick
carrier to receive a feather a formed on or carried by the extension a³ of the burner-
fitting a or other suitable means may be employed to attain this end.
In the arrangement represented at Figures 9, 10, 11 and 12 1 have shown the
invention applied to a lamp fitted with a flat wick burner.
This arrangement of parts is very similar to that herein before described with respect
to Figures 1, 2 and 3 but in this example the central air tube a¹ is necessarily dispensed
with and the corrugated or fluted wick carrier or tube c is flattened to correspond
with the shape of the wick tube d³ whilst the cylindrical forin of the collar or band c²
of the wick carrier c is retained in order to enable the carrier c together with the
burner d to be rotated in the act of attaching the burner to the burner-fitting a².
It will be evident that in this case also the extension a' of the burner-fitting a may
berdispensed with and the wick tube d³ may be extended downwardly in lieu thereof
in a similar manner to that represented at Figure 13.
:
In the example given at Figure 13-the invention is shown applied to a lamp of a
kind commonly employed in connection with oil stoves the arrangement of the parts
being similar to that represented at Figures 9, 10, 11 and 12 excepting that in this
case the extension a³ of the burner-fitting a is dispensed with and the wick tube d
is extended downwardly in lieu. thereof in a similar manner to that represented at
Figure 4 and downwardly projecting legs c³ are provided-upon the lower end of the
wick, carrier c.in order to limit the downward movement thereof.
In the modified form of wick carrier c represented at Figures 14, 15, 16 and 17 in
lieu of forming the corrugations or flutings spirally around the wick carrier cas
shown.and.described with respect..to the previous figures of the drawings they take
the form of annular rings or ribs but this construction is more especially applicable to

page_text: lamps where the oil trap is not required and a short wick carrier is consequently
employed.
I would here remark that although I have shown and described my improvements
in connection with lamps for burning hydrocarbon oils they are equally applicable to
lamps constructed to burn heavy oils but as they could be readily adapted thereto by
a competent mechanic I have not thought it necessary to give any special description
of such an arrangement.
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. In an oil lamp, a wick carrier consisting of a loose imperforate tube c surrounding
the wick 6 and extending nearly to the bottom of the oil container all in manner
substantially as herein shown and described and for the purpose stated.
2. In an oil lamp a wick carrier consisting of a loose imperforate tube c surrounding
the wick band formed with corrugations or flutings e arranged spirally or in annular
rings or ribs around the same and engaging a wick raiser d' all in manner substantially
as herein shown and described and for the purpose stated.
3. In an oil lamp the combination of a loose imperforate tube e surrounding the
wick band formed with corrugations or flutings carranged spirally or in annular
rings or ribs around the same, a band or collar c" upon the exterior of such tube c, a
similar band or collar 3 upon the interior thereof, a downward extension a³ of the
burner-fitting a or the wick tube d³ within which closely fits the band or collar c²,
and a wick raiser d' engaging the corrugations, flutings, or ribs of the tube
G all in
manner substantially as herein shown and described and for the purpose stated.
4. In an oil lamp, the combination of a loose imperforate tube c extending
nearly to the bottom of the oil container a and surrounding the wick b and
formed with corrugations or flutings carranged spirally or in annular rings or
ribs around the same, a band or collar cupon the exterior of such tube c a
similar band or collar c³ upon the interior thereof, a downward extension a³ of the
burner-fitting a² or the wick tube d³ within which closely fits the band or collar c
and a wick raiser engaging the corrugations, flutings, or ribs of the tube c,
all in manner substantially as herein shown and described and for the purpose
stated.
5. In an oil lamp, the combination of a central air tube a' passing through the
interior of the wick, a loose imperforate tube c and surrounding the wick b and
formed with corrugations or flutings c arranged spirally or in annular rings or
ribs around the same, a band or collar e upon the exterior of such tube c at
similar band or collar cupon the interior thereof, a downward extension of the
burner-fitting a² or the wick tube 3 within which closely fits the band or collar c²,
and a wick raiser engaging the corrugations or flutings or ribs c² of the tube c.
all in manner substantially as herein shown and described and for the purpose stated.
6. In an oil lamp, the combination of a central air tube a passing through the
interior of the wick, a loose imperforate tube c surrounding the wick and formed
with corrugations arranged spirally around the same a band or collar cupon the
exterior of such tube c, a similar band or collar c³ upon the interior thereof, a down-
ward extension a³ of the burner-fitting a², or the wick tube d³ within which closely fits
the band or collar c², a device c for preventing the rotation of the tube c, and a
horizontally rotating wick raiser d in the form of a nut engaging the spiral corru-
gations or flutings of the loose tube c, all in manner substantially as herein
shown and described and for the purpose stated.
