Year: 1866

page_text: LETTERS PATENT to Frederick Richard Mosley, of the Firm of Mosley
and Lloyd, of Birmingham, in the County of Warwick, Lamp Manu-
facturers, for the Invention of "IMPROVEMENTS IN LAMPS FOR BURNING
PROVISIONAL SPECIFICATION left by the said Frederick Richard Mosley
at the Office of the Commissioners of Patents, with his Petition, on the
22nd September 1866.
I, FREDERICK RICHARD MOSLEY, of the Firm of Mosley and Lloyd, of
Birmingham, in the County of Warwick, Lamp Manufacturers, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN LAMPS FOR
BURNING PARAFFIN OIL AND OTHER VOLATILE LIQUID HYDROCARBONS," to be as
follows:-
My Invention consists in constructing the wick holders or cases of circular
or Argand burners of lamps for burning paraffin oil and other volatile liquid
hydrocarbons in the manner herein-after described, whereby the introduction
of the circular wicks into the said burners is much facilitated.
The wick holders or cases of circular or Argand burners as ordinarily con-
structed consist of a circular tube at top around which the wick is placed,

page_text: and a semicircular tube at bottom, through which last-mentioned tube the
open parts of the wick are passed to fix it to the case or holder. In con-
.structing the wick cases or holders of circular or Argand burners according to
my Invention I dispense with the fixed semicircular tube described, and I use
three wicks, and fix them to the case or holder in the following manner :-I
make the whole of the wick case or holder of a circular tube, at the lower
end of which is a flange or shoulder. To this flange or shoulder I joint or
connect two clips or semicircular plates, the said plates being jointed at
opposite points of the flange. The said clips or semicircular plates are
capable of being turned back from the wick holder or case, or of closing or
nearly closing upon the wick case or holder. I place upon the wick case
above the flange described a circular wick, and I place on either side the said
curved wick a flat wick, which last-named wicks pass to the oil reservoir.
After the three wicks have been put in their places the pinion of the burner
is turned, and the wick case or holder and wicks are drawn into the burner,
and the semicircular clips or plates are turned upon their joints and made to
clip the side wicks and press them into close contact with the circular wick on
the wick holder. The three wicks are thereby connected together, the circular
wick being supplied with oil by the side flat wicks. Instead of semicircular
clips or plates, clips or plates of other figures may be used.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick Richard Mosley in the Great Seal Patent Office on
the 21st March 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
RICHARD MOSLEY, of the Firm of Mosley and Lloyd, of Birmingham, in the
County of Warwick, Lamp Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of September, in the year of our
Lord One thousand eight hundred and sixty-six, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Frederick Richard Mosley, Her special licence that I, the said Frederick
Richard Mosley, my executors, administrators, and assigns, or such others
as I, the said Fredorick Richard Mosley, my executors, administrators, and
assigns, should at any timé agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and

page_text: lawfully might make, use, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN LAMPS FOR BURNING PARAFFIN OIL AND OTHER
VOLATILE LIQUID HYDROCARBONS," upon the condition (amongst others) that I,.
the said Frederick Richard Mosley, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals;
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Frederick Richard Mosley, do hereby.
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by
the, following statement thereof, that is to say:-
My Invention consists in constructing the wick holders or cases of circular
or Argand burners of lamps for burning paraffin oil and other volatile liquid-
hydrocarbons, in the manner herein-after described, whereby the introduction
of the circular wicks into the said burners is much facilitated. The wick
holders or cases of circular or Argand burners, as ordinarily constructed,
consist of a circular tube at top around which the wick is placed, and a semi-
circular tube at bottom, through which last-named tube the open parts of the
wick are passed to fix it to the case or holder.
. In constructing the wick cases or holders of circular or argand burners,.
according to my Invention, I dispense with the fixed semicircular tube
described, and I use three wicks and fix them to the case or bolder in the
following manner :-I make the whole of the wick case or holder of a circular
tube, at the lower end of which is a flange or shoulder; to this flange or
shoulder I joint or connect two clips or semicircular plates, the said plates
being jointed at opposite points of the flange. The said clips or semicircular
plates are capable of being turned back from the wick case or holder, or of
closing or nearly closing upon the wick case or holder. I place upon the
wick case above the flange described a circular wick, and I place on either
side the said curved wick a flat wick, which last-named wicks pass to the
oil reservoir. After the three wicks have been put in their places the pinion
of the burner is turned, and the wick case or holder and wicks are drawn
into the burner and the semicircular clips or plates are turned upon their
joints and made to clip the side. wicks and press them into close contact with
the circular wick on the wick holder. The three wicks are thereby connected

page_text: together, the circular wick being supplied with oil by the side flat wicks;
instead of semicircular clips or plates clips or plates of other Figures may be
used.
Having explained the nature of my Invention, I will proceed to describe,
with reference to the accompanying Drawing, the manner in which the same
is to be performed.
Figure 1 represents in elevation, and Figure 2 in plan, a portion of a circular
or Argand burner for burning paraffin oil or other volatile liquid hydrocarbon,
constructed according to my Invention, the parts being in position for
receiving the wicks; Figure 3 represents in elevation, and Figure 4 in plan,
the same after the wicks have been placed in the wick holder or case and
fixed thereto, but before they are drawn into the burner; Figure 5 repre-
sents an elevation of the burner taken at right angles to that in which the
elevation, Figure 3, is taken after the wicks have been depressed into the
burner; and Figure 6 represents a vertical section of the complete burner
ready for use. The same letters indicate the same parts in each Figure of
the Drawing.
a is the wick case or holder of a circular figure, having a flange or shoulder b
at its bottom. Upon the case or holder a a circular wick c is placed; on
apposite sides of the flange or shoulder à semicircular clips or plates e, f, are
jointed at e, f, the said clips or plates. being capable of being turned back
from the wick case or holder a, as represented in Figures 1 and 2, or of closing,
or nearly closing upon the said case or holder, as represented in Figures 3
and 4. The said wick case or holder a slides upon the tube g fixed in the
axis of the burner, and motion is given to the said wick case or holder by
means of a pinion on the end of the axis i gearing with a rack k fixed on
the said case or holder (see Figure 1). By turning the axis i by its handle
the case or holder, a may he raised or lowered in the burner. Concentric or
nearly so with the tube g and the case a is a larger tube l, to which tube l
the shade holder or gallery m is connected. In the space between the inner
tube g and outer tube two flat wicks n, o, are placed (see. Figure 6), the
said flat wicks passing to the oil reservoir of the lamp. Around the top of
the tube is a nozzle piece p fixed thereto by a bayonet joint fastening 9, the
said nozzle piece preventing the wick case or holder a from being raised too
far out of the burner. The chimney holder r is supported upon the lower
part of the shade holder or gallery m.. Air is conveyed to the flame by per-
forations in the lower part of the chimney holder r, commonly called the wind
guard, and by openings s in opposite sides of the tube 7, the sail perforations s

page_text: opening into the inner tube g, the air passing up the said inner tube g, and
being deflected by the button t in the ordinary manner.
In fixing the circular wick c and flat wicks n, o, in the burner I remove tlie
chimney holder r and nozzle piece p, and raise the wick case or holder a
above the outer tube l, and throw back the clips e, f, into the position repre-
sented in Figures 1 and 2. I place the circular wick c upon the case or
holder a above the flange b, and place on either side the said circular wick
flat wicks n, o, which wicks n, o, pass down between the tubes g, l, to the oil
reservoir of the lamp, the said wicks being bent into a nearly semicircular
figure. After the three wicks c, n, o, have been put in their places the
pinion h is turned by means of its axis i, and the case or holder a is drawn.
into the burner. On the semicircular clips or plates e, f, reaching the top of
the tube / they are turned upon their joints and carried into the burner and
made to clip the side wicks n, o, and press them into close contact with the
circular wick c on the wick holder a; the three wicks c, n, o, are thus con-
nected together, and on using the lamp the circular wick is supplied with oil
by the side wicks passing to the reservoir. Instead of closing the clips e, f,
upon the side wicks by the depression of the circular wick holder a, the said
clips may be closed upon the said wicks before the holder a is drawn into the
burner.
Figures 3 and 4 represent the position of the three wicks just before the
wick case or holder a and fixing clips e, f, are drawn into the burner, and by
an examination of the said Figures 3 and 4, the position of the side wicks
with respect to the circular wick will be readily seen. After the wick case or
holder a and parts carried by it have been depressed in the burner to the
position represented in Figure 6 the nozzle piece p and chimney holder r are
put in their respective places, when the burner is ready for use. Instead of
the semicircular clips or plates e, f, described and represented, clips or plates
of other figures may be employed with the same or nearly the same effect.
By the use of my Invention, the wicks of circular or Argand burners are
fixed in their places with greater facility and ease than in circular or argand
burners of the ordinary construction.
Having now described the nature of my Invention, and the manner in
which the same is to be performed, I wish it to be understood that I do not
limit myself to the precise details herein described and represented in the
Drawing, as the same may be varied without departing from the nature of
my Invention; but I claim as my Invention the improvements in lamps for
burning paraffin oil and other volatile liquid hydrocarbons, herein-before

page_text: described and illustrated in the accompanying Drawing, that is to say, con-
structing the circular wick holders or cases of the said lamps of a tube upon
which the circular wick is fixed, the said circular wick being fed with oil by
means of side wicks fixed to and pressed into close contact with the circular
wick by means of semicircular or other shaped clips or plates jointed to the
circular wick case or holder, substantially as described and illustrated.
In witness whereof, I, the said Frederick Richard Mosley, have here-
unto set my hand and seal, this Nineteenth day of March, in the year
of our Lord One thousand eight hundred and sixty-seven.
Witness,
GEORGE SHAW.
