I, BARUCH CARS of 2 Academy Buildings, Fanshaw Street, Hoxton, in the
County of Middlesex, Lamp Manufacturer do hereby declare the nature of this
invention partly the result of a .communication to me from abroad by Jacob
Hirschhorn of 149 Köpenicker Strasse Berlin in the Empire of Germany, Lamp
Manufacturer and partly my own invention. to be as follows:-
The invention relates to improvements upon that class of stove in respect of
which Charles Melbourne White has filed a Complete Specification in pursuance
of his application for Letters Patent dated the 11th day of May 1894 No. 9360
and in which the stove is formed of a separate tubular pedestal or casing of round
or other suitable section, whilst the lamp is loose within the casing and is surmounted
with an inner body or chimney which seats upon the burner casing and is adapted
to be raised off the burner in order to facilitate the lighting or trimming of the
lamp and the object of the present invention is to guide the inner body or chimney
in its vertical movements and to fix it in its raised position at the times desired.
For this purpose the outer body or pedestal is formed with an opening at. the
front closed by means of folding doors to enable the lamp to be introduced and
removed therefrom one of the doors being made to overlap the other and with a
projection on its underside to engage a recess in the base of the stove in order to
retain the same in its closed position when desired.
The lamp body is furnished with several tubular posts which extend some
distance into the reservoir in order to afford the necessary length and the inner
body or chimney is provided with corresponding legs which are received tele-
scopically into the tubular posts so that the inner body or chimney may by means
of a knob or handle be raised or lowered at the times desired the tubular posts.and
legs efficiently guiding it in its movements, whilst the upper part of the outer body
or pedestal forms a stop to prevent the separation of the parts when the lamp is
within the outer body or pedestal.
In order to retain the inner body or chimney in its raised position during the
lighting or trimming of the lamp, one of the tubular posts is formed with a
horizontal slot or opening therein to receive a disc plate or stop which is preferably
hinged to the post and provided with a thumb piece by means of which it may be
turned into or out of position.
This stop in the raised position of the inner body or chimney comes beneath.or
engages that particular leg and holds the inner body or chimney securely in its
raised position at the times desired.
Or if desired in lieu of forming the slot in one of the posts a notch may be
formed in one of the legs and the hinged stop may be mounted at the top of the
tubular post in a suitable position to engage the notch of the leg.
Or one of the legs might be formed short to engage a plate or stop upon one
of the tubular guides.
Or one of the legs might be formed with a spring catch to engage the top of one
of the tubes.
By these means the lamp together with the inner body or chimney is rendered
independent of the outer body or pedestal for the means of guiding & fixing it in.its
raised position so that it may without trouble be readily removed together with
the lamp from the outer body or pedestal.

I, BARUCH CARS of 2 Academy Buildings, Fanshaw Street, Hoxton in the
County of Middlesex, Lamp Manufacturer do hereby declare the nature of this
invention partly the result of a communication to me from abroad by Jacob
Hirschhorn of 149 Köpenicker Strasse Berlin in the Empire of Germany, Lamp
Manufacturer, and partly my own invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:-
:.
The invention relates to improvements upon that class of stove in respect of
which Charles Melbourne White has obtained Letters Patent dated the 11th day
of May 1804 No. 9360, and according to which the stove is formed of a separate
tubular pedestal or casing of round or other suitable section, whilst the lamp is
loose within the casing and is surmounted with an inner body or chimney, which
seats upon the burner casing, and is adapted to be raised off the burner in order
to facilitate the lighting or trimming of the lamp, and the object of the present
invention is to guide the inner body or chimney in its vertical movements and to
fix it in its raised position at the times desired.
For this purpose the outer body or pedestal is formed with an opening at the
front closed by means of folding doors to enable the lamp to be introduced and
removed therefrom, one of the doors being made to overlap the other, and with a
projection on its underside to engage a recess in the base of the stove in order to
retain the same in its closed position when desired.
The lamp body is furnished with several tubular posts which according to one
arrangement, extend some distance into the reservoir in order to afford the
necessary length, and the inner body or chimney is provided with corresponding
legs which are received telescopically into the tubular posts so that the inner body
or chimney may by means of a knob or handle be raised or lowered at the times
desired the tubular posts and legs efficiently guiding it in its movements, whilst
the upper part of the outer body or pedestal forms a stop to prevent the separation
of the parts when the lamp is within the outer body or pedestal.
In order to. retain the inner body or chimney in its raised position, during the
lighting or trimming of the lamp, one of the tubular posts is formed with a hori-
zontal slot or opening therein to receive a disc plate or stop which is preferably
hinged to the post and provided with a thumb piece by means of which it may be
turned into or out of position.
:
This stop in the raised position of the inner body or chimney comes beneath or
engages that particular leg and holds the inner body or chimney securely in its
raised position at the times desired.
-
Or if desired, in lieu of forming the slot in one of the posts a notch may be
formed in one of the legs and the hinged stop may be mounted at the top of the
tubular post in a suitable position to engage the notch of the leg.
Or one of the legs might be formed short to engage a plate or stop upon one of
the tubular guides.

page_text: Or one of the legs might be formed with a spring catch to engage the top of
one of the tubes.
By these means the lamp together with the inner body or chimney is rendered
independent of the outer body or pedestal for the means of guiding and fixing it in
its raised position so that it may without trouble be readily removed together with
the lamp from the outer budy or pedestal:
It will be evident that other means than those berein before described may be
employed for fixing the inner body or chimney in its raised position, whilst still
preserving the essential features of this invention namely the tubular guides and
legs.
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
:
Figure 1 is a front elevation with the doors closed of a lamp stove embodying
the present invention.
Figure 2 is a similar view but with the doors open so as to expose the contained
lamp and showing the inner body or chimney in its raised position.
Figure 3 is a horizontal section taken on the line 1-1 of Figure 1.
Figure 4 is a front elevation of the lamp separately and showing the parts in
their normal positioni
Figure 5 is a vertical section of parts showing in their normal positions ónë of
the tubular posts, the corresponding leg and the co-acting stop.
Figure 6 is a horizontal section taken on the line 2-2 of Figure 5.
Figure 7 is an elevation of the parts represented at Figure 5 drawn at right angles
thefĕto.
Figure 8 is a similar view to Figure 5, but representing the leg in its raised
position and there held by the co-acting stop.
Figure 9 is a horizontal section taken on the line 3-3 of Figure 8.
Figures 10, 11 and 12 are similar views to Figure 8, but taken at right angles
thereto and representing slight modifications in the arrangement and means for
carrying the invention into effect.
In the several figures in which like parts are indicated by similar letters of
an increased scale with respect to
reference Figures 5 to 12 are drawn to
Figures 1 to 4.
"
Referring to Figures 1 to 9 a represents the outer body casing or pedestal of
the lamp stove which is formed with an opening in the front thereof as seeh
more clearly at Figure 2 and which is adapted to be opened or closed by means
of folding doors a so as to enable the lamp to be introduced and removed there-
from at the times desired, and in order to hold the doors in their closed position
one is formed to overlap the other, and each is formed with a rounded stud or
projection a³ on its underside whilst the doors are capable of slight vertical
movement on their hinges so that the studs a' are adapted to snap into recesses a
in the base of the stove at the front thereof, and thus retain the doors in their
closed position at the tinies desired.
6 represents the base body or reservoir of the lamp which is furnished with
several tubular posts or sockets b' arranged around and located at a suitable
distance from the burner, closed at the lower end and which extend to the bottom
of or some distance into the reservoir or body b of the lamp in order to afford the
U necessary lengtli to efficiently guide the inner body or chimney c as hereinafter
described.
The inner body or chimneye is provided with corresponding legs which are
received telescopically into the tubular posts b¹ and take a bearing upon the closed
lower ends of such tubular posts so that the inner body or chimney c may by
5 means of a knob or handle located at the front thereof be raised at the times

page_text: desired into the position indicated at Figure 2 or lowered as indicated at Figure 4,
the tubular posts 6 and legs e efficiently guiding it in its movements.
When the lamp is within the outer body, or pedestal a the upper part thereof or
one of the projecting bolts a forms a stop to prevent the separation of the parts,
that is to say of the inner body c from the base or reservoir b, whilst by sinking
the lower parts of the tubular posts or guides 6' within the lamp body or reservoir b
the legs are enabled to be formed of such a length as to afford the necessary
upward movement to the inner chimney c for lighting without disengaging the legs c
from the tubular posts b¹.
the
In order to retain the inner body or
lighting or trimming of the lamp one of the tubular posts 6 is formed with a
chimney c in its raised position during
horizontal slot or opening 62 therein to receive a disc plate or stop 68 as shown more
clearly at Figures 5 to 9 which is preferably hinged "to the post b¹ and provided
with a tail or thumb piece 64 by means of which it may be turned out of action
as indicated at Figures 3 to 7 or into action as indicated at Figures 2, 8 and 9.
This stop 68 in the raised position of the inner body or chimney as indicated at
Figures 2, 8 and 9 comes beneath or engages the leg a telescoping into the tubular
post 6 to which the stop 6 is hinged and thus holds the inner body or chimney c
securely in its raised position, at the times desired, whilst when the lamp 6 is
removed from the pedestal or body a as represented at Figure: 4, the inner body or
chimney e may be readily separated from the lamp b, to facilitate the cleaning
thereof, or for other purposes.
In the example given at Figure 10, the slot 62 in the tubular post 6' is dispensed
with and in lieu thereof a notch or recess c² is formed in one of the legs o' and the
co-acting hinged stop 68 is mounted at the top of the tubular post b¹ in a suitable
position to engage the notch c² of the leg c
In the example given at Figure 11 in lieu of forming a notch c, in the leg c¹ to
engage the hinge stop 6 one of the legs c¹ is formed shorter than the others so that
in the raised position of the inner body or chimney c. it will rest upon the hinged
stop 6 which is mounted at the top of one of the tubular, guides or posts in a
similar manner to that represented at Figure 10.
In the example given at Figure 12 the legs. c are formed all of the same length
and in lieu of the hinged plate or stop 68 hereinbefore described a catch 6ª is hinged
in a recess in the side of one of the legs c¹ and is pressed outward by means of a
spring so that upon raising the inner body or chimney to the maximum height 3
the spring catch 6 will engage the top edge of the co-acting tubular post or guide b
and thus retain the inner body or chimney c in its raised position, whilst by
pressing inward the spring catch 6 the inner body or chimney c may be readily
fowered to its normal or working position.
By these means the lamp 6 together with the inner body or chimney c is rendered
independent of the outer body or pedestal a for the means of guiding and fixing
the chimney c in its raised position so that it may without trouble be readily
removed together with the lamp 6 from the outer body or pedestal d, whilst by
reason of the peculiar arrangement of the tubular posts and legs, the burner remains
uninterfered with and a broad base is at the same time formed for the steady 4
guidance of the inner body or chimney.
S
Although the tubular posts b¹ are herein before shown and described as sunk
within the lamp or reservoir b it will be evident that without departing from the
present invention a similar mechanical effect might be obtained by fixing them
upon the exterior thereof, but the former is the neater and therefore the preferred 5
arrangement.
It will also be evident that other means than those hereinbefore shown and
described may be employed for fixing the inner body or chimney in its raised
position whilst still preserving the essential features of the present invention namely
the tubular posts or guides and legs arranged around and at a suitable distance from 55
the burner.
I am aware that it has before been proposed in connection with lamps to mount

page_text: he cone and gallery upon legs in order to enable the cone and chimney to ve nived
off the wick tubes for the purpose of trimming and lighting the lamp, but in that-
arrangement the burner was perforated to allow of the passage of the legs there-
through into the reservoir thus admitting false draughts to the flame of the lamp.
whilst the tubular posts or guides rising above the reservoir and descending into
the same were entirely absent, and the legs simply passed through the aforesaid
perforations in the burner fitting into the reservoir, and there was consequently
a risk of the vapour from the oil issuing through such apertures and mingling with.
the air passing to the flame of the lamp and this device for the above and other
reasons would be unsuitable for the purposes of this invention.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A lamp stove comprising a base or reservoir provided with several tubular posts
or guides descending a considerable distance below the level of the top of the
reservoir or base and arranged around and at a suitable distance from the burner
a body or chimney provided with corresponding legs telescopically fitting the.
tubular posts or guides and means for holding the body or chimney in its raised
position substantially as herein shown and described and for the purpose stated.
2. A lamp stove comprising a base or reservoir provided with several tubular
posts or guides descending a considerable distance below the level of the top of the
reservoir or base and arranged around and at a suitable distance from the burner,
a body or chimney provided with corresponding legs telescopically fitting the
tubular posts or guides and a spring or other stop for engaging the leg or the post
and holding the body or chimney in its raised position, substantially as herein shown
and described and for the purpose stated.
3. A lamp stove comprising a base or reservoir provided with several tubular
posts or guides descending a considerable distance into the reservoir or base
closed at their lower ends and arranged around and at a suitable distance from
the burner, a body or chimney provided with corresponding legs telescopically
fitting the tubular posts or guides and means for holding the body or chimney
in its raised position substantially as herein shown and described and for the
purpose stated.
4. A lamp stove comprising an outer casing or pedestal, a lamp base or
reservoir provided with several tubular posts or guides descending a considerable
distance below the level of the top of the reservoir or base and arranged around
and at a suitable distance from the burner, an inner body or chimney provided with
corresponding legs telescopically fitting the tubular posts or guides, means for
holding the inner body or chimney in its raised position and a stop formed or
carried by the pedestal or casing for engaging the inner body or chimney and
limiting the upward movement thereof, substantially as herein shown and described
and for the purpose stated.
Deted this 18th day of November 1895.
