CERTAIN IMPROVEMENTS IN MINING LAMPS
Year: 1869

page_text: LETTERS PATENT to Fountain Clarbour and William Edward Teale,"
both of Salford, in the County of Lancaster, Agents, for the
Invention of "CERTAIN IMPROVEMENTS IN MINING LAMPS."
Sealed the 6th May 1870, and dated the 15th November 1869.
PROVISIONAL SPECIFICATION left by the said Fountain Clarbour and
William Edward Teale at the Office of the Commissioners of Patents,
with their Petition, on the 15th November 1869.
We, FOUNTAIN CLARBOUR and WILLIAM EDWARD TEALE, both of
Salford, in the County of Lancaster, Agents, do hereby declare the
nature of the said Invention for "CERTAIN IMPROVEMENTS IN MINING LAMPS,'
to be as follows:-
Our Invention relates to certain improvements in mining lamps, and
consists in the application and arrangement of hinges, levers, or
springs working in conjunction with a lamp regulator or extinguisher
in such a manner as to entirely prevent a miners' lamp being opened
without extinguishing the light.

page_text: In carrying our Invention into effect we apply to the wick tube of a
lamp a sliding tube, which is capable of being moved up and down over
the wick tube so as to regulate or extinguish the light. Attached to
the said sliding tube is a circular flange. We attach to the framework
or body of the lamp one or more hinges, levers, or springs in such a
manner that on closing the lamp the flange of the sliding tube will come
in contact with the said hinges, levers, or springs, and will elevate them
in passing. We also attach to the body of the lamp one or more stops
or inetal points which regulate the traverse of the sliding tube by their
action upon the flange thereof. When the flange of the sliding tube has
passed the hinges, levers, or springs they will then fall to their former
position, and on opening the lamp the flange of the sliding tube will
come in contact with the hinges, levers, or springs in an opposite
direction, which offering resistance the sliding tube will be gradually
drawn over the lamp wick, and so put out the light.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Fountain Clarbour and William Edward Teale in
the Great Seal Patent Office on the 14th May 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FOUNTAIN
CLARBOUR and WILLIAM EDWARD TEALE, both of Salford, in the
County of Lancaster, Agents, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of November, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Fountain Clarbour and William Edward
Teale, Her special license, that we, the said Fountain Clarbour and
William Edward Teale, our executors, administrators, and assigns, or
such others as we, the said Fountain Clarbour and William Edward
Teale, our executors, administrators, or assigns, should at any time agree
with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and 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

page_text: "CERTAIN IMPROVEMENTS IN MINING LAMPS," upon the condition (amongst
others) that we, the said Fountain Clarbour and William Edward Teale,
our executors or administrators, by an instrument in writing under
our 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 we, the said Fountain Clarbour and William
Edward Teale, do hereby declare the nature of our said Invention, and
in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement, reference being had
to the Drawings hereunto annexed, and to the letters and figures marked
thercon (that is to say):-
Our said Invention relates to certain improvements in mining lamps,
and consists in the application and arrangement of hinges, levers, or
springs working in conjunction with a lamp regulator or extinguisher
in such a manner as to entirely prevent a miners' lamp being opened
without extinguishing the light.
In carrying our Invention into effect we apply to the wick tube of a
lamp a sliding tube, which is capable of being moved up and down over
the wick tube so as to regulate or extinguish the light. Attached to
the said sliding tube is a circular flange. We attach to the framework
or body of the lamp one or more hinges, levers, or springs in such a
manner that on closing the lamp the flange of the sliding tube will
come in contact with the said hinges, levers, or springs, and will elevate
them in passing. We also attach to the body of the lamp one or more
stops or metal points, which regulate the traverse of the sliding tube by
their action upon the flange thereof. When the flange of the sliding
tube has passed the hinges, levers, or springs they will then fall to their
former position, and on opening the lamp the flange of the sliding tube
will come in contact with the hinges, levers, or springs in an opposite
direction, which offering resistance the sliding tube will be gradually
drawn over the lamp wick, and so put out the light.
And in order that our said Invention may be fully understood, we
shall now proceed more particularly to describe the same, and for that
purpose shall refer to the several Figures on the annexed Sheet of

page_text: Drawings, the same letters of reference indicating corresponding parts
in all the Figures.
: Figure 1 shews a sectional view of the outer case of a miners' lamp,
to the body of which is screwed a circular gallery or disc of metal A, A.
Upon this gallery or disc are fixed two short levers or catch hinges B, B,
working upon pins c, c; the levers or catch hinges are at liberty to
move upwards only, the lower part or heel of said lever or catch hinges
resting firmly against a buttress formed in the gallery or disc A, A, as
shewn in Figure 1; to the gallery or disc A, A, are also fixed two
stops D, D, see Figures 1, 6, and 8.
Figure 3 shews a tube e upon which is fixed a flange or disc F, shewn
in section, Figure 2 and Figure 7. The tube e is made to slide casily
over the wick tube of the lamp.
In order to carry our Invention into practical effect we place the
tube e over the wick tube of the lamp, as shewn in Figures 2, 4, and 5.
We then light the lamp and screw it into its outer case, as shewn in
Figure 4, when the flange or disc F comes in contact with the levers or
catch hinges B, B, and lifts them in passing, when the lamp is screwed
home to its position, as shewn Figure 5. The flange F will have
passed the levers or catch hinges, and they will then fall to their former
position (see Figure 5), and the upper edge of the flange or disc F will be
in contact with the stops D, D, as shewn by the dotted lines in Figure 6,
which effectually prevent the tube e being displaced or drawn over the
light by accident. In opening the lamp the flange or disc F comes in
contact with the upper surface of the levers or catch hinges B, B, and
rests upon them while the lamp along with the wick tube is withdrawn,
and gradually extinguishes the light (see Figure 7).
Figure 9 shews a modification of our Invention wherein we dispense
with the levers or catch hinges B, B, and use instead thereof two
springs g, g. The springs are at liberty to move upwards so that the
flange or disc F may pass when the lamp is screwed home to its position,
when they will afterwards fall to the position represented by the dotted
lines resting upon a tongue of metal h, h, which is continued from and
forms part of the circular gallery or disc A, A.
Having now described and particularly ascertained the nature of our
said Invention, and the manner in which the same is or may be used or
carried into effect, we would observe in conclusion that what we consider

page_text: to be novel and original, and therefore claim as the Invention secured to
us by the herein-before in part recited Letters Patent is, the applica-
cation and use of a sliding tube carrying a flange or disc working in
combination with levers, catch hinges, or springs for the purpose of
extinguishing the light in miners' lamps when such lamps are opened,
as herein-before described and illustrated in our Drawings.
In witness whereof, we, the said Fountain Clarbour and William
Edward Teale, have to this our Specification set our hands and
scals, the Eleventh day of May One thousand cight hundred and
seventy.
