We EDWARD ALEXANDER RIPPINGILLE and JAMES DAVEY RIPPINGILLE both of
The Aston Brook Lamp Works, Aston-juxta-Birmingham in the County of Warwick,
Lamp Manufacturers do hereby declare the nature of this invention to be as
follows:-
The invention has for its object improvements in oil lamps and relates Firstly
to means for facilitating the adjustment in height of a reading lamp and Secondly to
improvements in burners for the same and for other descriptions of oil lamps.
According to the first part of our invention the lamp is mounted with capability of
adjustment in height on one or more uprights carried by a suitable base, the lamp
being balanced by a weight or weights. The lamp is carried by a ring or basket
provided with tubes or clips which slide up and down the said uprights or the said
ring or basket may be carried by an arm provided with one or more tubes or clips to
fit one or both of such uprights or the said supporting ring and tubes or clips may be
dispensed with and the font or reservoir may be of annular or other form and provided
with guides or fittings to slide up and down the uprights.
The supporting ring or basket or the font or reservoir is connected by one or more
chains to one or more counter-balance weights such chains passing over one or more
guide pulleys or fixed segments carried at the upper part of the uprights; the weight
or weights is or are guided by the upright or uprights and may either surround or
work within or between such uprights. Or the font or reservoir may be guided by
one upright and the weight by another or a single tubular upright of any suitable
section may be employed in combination with a font or reservoir surrounding the same
or carried by an arm provided with a tubular socket fitting around the said upright
in which case the weight would slide up and down within the tubular upright.
Or a single upright may be employed which is so grooved or shaped as to enable
the font or font support to slide up and down one part thereof, and the weight on
another part thereof.
The base may be sufficiently weighted to hold the lamp firmly or it may be
provided with suitable holding or clamping means to fix it to any suitable article
or support.

page_text: In cases where the light is required to be held at a lower level than the base of the
lamp we connect the upright or uprights to the base by any suitable extension arm or
slide which can when required be moved forward so as to cause the upright or
uprights to extend beyond the edge of the support carrying the base of the lamp and
we arrange the upright or uprights to slide up and down on such extension. arm
or slide so as to enable such uprights, and consequently the lamp to be carried below
the said support.
In all the arrangements, spring or other friction is employed to retain the lamp in
the required position.
The invention relates, Secondly to a slight modification of a burner described and
shown in the specification of Letters Patent dated January 24th 1884 No. 2048 for
the purpose of simplifying and cheapening the manufacture thereof.
For this purpose we form the burner with a cylindrical or slightly conical fitting
and instead of rivetting or soldering studs or catches in the same we raise up such
catches or studs from the body thereof, the carrier fitting is formed to rest upon and
fit the said cylindrical or slightly conical burner fitting and side slots to receive
such studs or catches are formed in the carrier fitting which at one end communicate
with a raised circumferential recess to permit the said studs to pass freely out of
the said slots into such raised recess and the latter at its other end is inclined down-
wards to a short flange which terminates at the beginning of the adjoining recess, by
which means the carrier fitting when rotated in one direction, as described in the
specification hereinbefore referred to, will run free of such studs or catches, but when
rotated in the contrary direction will cause such studs or catches to enter the said side
slots and to become locked in proper position when such studs have come to the
stopping end of the said slots. If desired the studs or catches may be carried by the
carrier fitting and the slots and circumferential recesses and connected parts by
the burner fitting.

The Aston Brook Lamp Works, Aston-juxta-Birmingham in the County of Warwick,
Lamp 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:-
The Invention. has for its object improvements in oil lamps and relates Firstly
to means for facilitating the adjustment in height of a reading lamp and Secondly to.
improvements in burners for the same and for other descriptions of lamps.
According to the first part of our invention the lamp is mounted with capability of
adjustment in height on one or more uprights carried by a suitable base, the lamp
being balanced by a weight or weights.
The lamp is carried by a ring or basket provided with tubes or clips which slide
up and down the said uprights, or the said ring or basket may be carried by an arm
provided with one or more tubes or clips to fit one or both of such uprights, or the
Said supporting ring and tubes or clips may be dispensed with and the font or
reservoir may be of annular or other form and provided with guides or fittings to
slide up and down the uprights.
The supporting ring or basket or the font or reservoir is connected by one or more
chains to one or more counterbalance weights, such chains passing over one or more
guide pulleys or fixed segments carried at the upper part of the uprights; the weight
or weights is or are guided by the upright or uprights and may either surround or
work within or between such uprights.
Or the font or reservoir may be guided by one upright and the weight by another
or a single tubular upright of any suitable section may be employed in combination
with a font or reservoir surrounding the same or carried by an arm provided with a
tubular socket fitting around the said upright in which case the weight would slide up
and down within the tubular upright. Or a single upright may be employed which is
so grooved or shaped as to enable the font, or font support to slide up and down one
part thereof and the weight on another part thereof.
The base may be sufficiently weighted to hold the lamp firmly or it may be provided
with suitable holding or clamping means to fix it to any suitable article or support.
In cases where the light is required to be held at a lower level than the base of the
lamp we connect the upright or uprights to the base by any suitable extension arm
or slide which can when required be moved forward so as to cause the upright or
uprights to extend beyond the edge of the support carrying the base of the lamp and
we arrange the upright or uprights to slide up and down on such extension arm or
slide so as to enable such uprights and consequently the lamp to be carried below the
said support.
In all the arrangements spring or other friction is when required employed to retain
the lamp in the required position.

page_text: The invention relates Secondly to a slight modification of a burner described and
shown in the Specification of Letters Patent dated January 24th 1884 No. 2048 for
the purpose of simplifying and cheapening the manufacture thereof.
For this purpose we form the burner with a cylindrical or slightly conical fitting
and instead of rivetting or soldering studs or catches in the same, we raise up such
catches or studs from the body thereof, the carrier fitting is formed to rest upon and
fit the said cylindrical or slightly conical burner fitting and side slots to receive such
studs or catches are formed in the carrier fitting which at one end communicate with a
raised circumferential recess to permit the said studs to pass freely out of the said slots
into such raised recess and the latter at its other end is inclined downwards to a short
flange which terminates at the beginning of the adjoining recess, by which means the
carrier fitting when rotated in one direction as described in the Specification herein
before referred to, will run free of such studs or catches but when rotated in the
contrary direction such studs or catches will be caused to enter the said side slots and
to become locked in proper position when such studs have come to the stopping end of
the said slots. If desired the studs or catches may he carried by the carrier fitting
and the slots and circumferential recesses and connected parts by the burner fitting.
Our invention is represented in the accompanying drawings in the various figures
of which like parts are indicated by similar letters of reference.
According to the first part of our invention the lamp is mounted with capability of
adjustment in height on one or more uprights carried by a suitable base, the lamp
being balanced by a weight or weights.
The first part of our invention is represented in the accompanying drawings at
Figures 1 to 15.
In the arrangement represented at Figures 1 and 2 which are respectively an
elevation partly in section and a plan of one form of our improved oil lamps, the lamp
reservoir a is supported in a ring which is provided with guiding tubes or clips
which slide up and down the uprights c¹ supported by a base c. Such ring is also
by chains & passing over suitable guide pulleys e connected to counter-balance weights f
which slide up and down between the uprights c¹.
In the modification shown at Figures 3 and 4 which are respectively an elevation
partly in section and a plan of an oil lamp, the ring or basket is carried by an arm b
provided with a tube or clip to fit one of the uprights c', the supporting chain d
passes around a fixed segmentg which connects the upper ends of the two uprights e¹ e¹
and the counterbalance weight instead of being enclosed within one of the uprights c¹
is made to surround the same.
In this modification the two uprights c¹ c¹ are carried by an extension arm which
is connected to the base by one of such uprights so as to enable the arm c² to be
capable of being turned, either into the position shown by the full lines of into the
position shown by the dotted lines a pin c being passed through a hole in the arm c²,
ca
into one or other of two holes formed in the base c in order to retain the arm c², in
either position as may be required.
When the parts are in the position shown by the full lines of the drawing the lamp
is capable on account of the shape of the arm of being placed in such position as to
be below the base whilst when the parts are in the dotted position the lamp can only
occupy a position above such base c.
C
In the modification represented in elevation and in sectional plan at Figures 5 and 6
only a single upright c' is employed upon which the tube. or clip & carrying the ring
or basket 6 is capable of sliding whilst the counter balance weight f is placed within
the upright c¹ the guide wheels or rollers e. e. being so placed at the upper part of the
upright c as to guide the chains d. d. correctly. In this case the upright is formed
of a tube, in opposite sides of which guiding grooves c are formed, and the weight
and tube or clip 6' are so formed as to fit respectively the inner and outer faces of
such parts in order to secure the lamp and weight against turning around and
within the upright e¹.
In the modification shown in elevation and in sectional plan at Figures 7 and 8 the
ring or basket band tube or clip bare dispensed with and the font or reservoir a is of

page_text: annular form and provided with guiding grooves a to fit and slide up and down the
outsides of the uprights c¹. In this modification the uprights are connected
together at their upper ends by a connection as shown or of other suitable shape, and
the weight is formed with guiding grooves to fit the inner faces of the uprights c
and slides up and down between, such uprights.
:
In the modification represented in elevation partly in section and in sectional plan
at Figures 9 and 10 a single tubular upright e is employed to guide both the lamp
font or reservoir a and the weight, the former being generally of annular form but.
provided with projecting guides a to fit the grooves formed in opposite sides of the
tubular upright and the weight being formed with guiding grooves to fit the
inner face of the grooves c. In the modification shown in elevation and in sectional
plan at Figures 11 and 12 a single upright is employed which is so grooved or
shaped on opposite sides thereof at e as on one side to receive and guide the part 63
carrying the ring or basket band on the other to receive and guide a projection.
from the weight.
Figure 13 is a plan, Figure 14 is a side elevation partly in section and Figure 15 is
a front view representing another modification of our improvements in oil lamps. In.
this case the two uprights c', are connected together at the top and bottom thereof and
one of them is fitted with capability of sliding up and down in a guide formed in an
extensible arm in which it may be fixed in any required. position by a binding
screw . The arm is made to slide to and fro in a straight line upon the base c and
capable of being clamped in any desired position thereon by a binding screw so as
to enable the uprights e c¹ to be arranged so as more or less to project beyond the
base c, thereby enabling such a lamp to be placed with its base or support upon the top
of a piano while the lamp is supported at a level below such base or support c and in
order to prevent the lamp from sliding forward, an adjustable catch is arranged in
the base G, and is fixed in any desired position by a screw or fly nut 4 so as to enable
it to catch at the back of the piano top. If desired such cateli 4 may be formed with
a hook to catch underneath the piano top, or the lamp may be provided with a holding or
clamping means of any suitable form to enable it to be readily fixed to any required
article or support.
In the modification represented in elevation partly in section at Figure 16 and in
plan partly in section at Figure 17 the lamp font or reservoir a is arranged to surround
and slide up and down one upright e whilst the weight surrounds and slides up and
down the other upright cl the two uprights being connected together at their upper
ends by a fixed segment through which the chain & passes to both lamp font and
weight. The lamp font or reservoir is in this case formed with a tubular arin to carry
the burner.
In all the above described modifications spring or other friction is when required
employed to retain the lamp in the required position.
We will now describe the second part of our invention which relates to a slight
modification of a burner, described and shown in the Specification herein before referred
to for the purpose of simplifying and cheapening the manufacture thereof.
We will first describe the modification represented at Figures 18 to 23. Figure 18
is a vertical section. Figure 19 is a plan. Figure 20 is an elevation of the improved
burner, drawn at right angles to Figure 18. Figure 21 is a vertical section of the
carrier separately taken on the line 1. 1. of Figure 19. Figure 22 is an elevation of
the burner without the carrier and Figure 23 is an elevation partly in section drawn at
right angles to Figure 22.
According to this part of our invention we form the burner with a cylindrical or
slightly conical fitting, and instead of rivetting or soldering studs or catches in the
same, we raise up such catches or studs from the body thereof, the carrier fitting k
is formed to rest upon and fit the said cylindrical or slightly conical burner fitting i
and side slots A¹ to receive such studs or catches are formed in the carrier fitting k
which slots at one end communicate with a raised circumferential recess ² to permit
the said studs or catches to pass freely out of the said slots into such raised
recess ² and the latter at its other end is inclined downwards to a short flange k³,

page_text: which terminates at the beginning of the adjoining recess, by which means the
carrier fitting & when, rotated in the direction of the arrow see Figure 20 will run free
of such studs or catches but when rotated in the contrary direction such studs or
catches will be caused to enter the said side slots and to become locked in proper
position when such studs or catches have come to the stopping end of such slots &.
A modification of the above burner is shown at Figures 24 to 27. Figure 24 being
a vertical section of the burner and carrier complete taken on the line 2-2 of Figure 27
Figure 25 being an elevation of the burner the carrier fitting shown in dotted lines
Figure 26 being a vertical section taken on the line 3. 3 of Figure 27 and Figure 27 a
sectional plan of the burner one half being without the carrier, the other half
representing a sectional view of the same in position thereon.
In this modification the studs or catches are formed on the carrier fitting. k and
the slots recess & short flange are formed in the burner fitting i.
Having now particularly described and ascortained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is
1. The improvements in that class of oil lamps commonly known as reading lamps
or. table lamps whereby the lamp is adjustable in height and otherwise substantially as
herein shown and described.
2. In table or reading oil lamps adjustabaly supporting the font or reservoir by one
or more counterbalance weights and uprights substantially as herein shown and
described.
3. The peculiar construction of burner substantially as herein shown and described
and for the purpose stated.
