IMPROVEMENTS IN EXTINGUISHERS TO CANDLES, AND IN THE APPLI- CATION OF SUCH EXTINGUISHERS TO CANDLES AND CANDLESTICKS
Year: 1835

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
WALKER, of Burslem, in the County of Stafford, Mechanic, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Third day of July, in the sixth year of His reign, did,
for Himself, His heirs and successors, give and grant unto me, the said Thomas
Walker, His especial licence, full power, sole privilege and authority, that 1.
tho said Thomas Walker; my exors, adiñors, and assigns, or such others as
I, the said Thomas Walker, my exors, adñiors, or assigns, should at any time
agree with, and no others, from time to time and at all times during the term
of years therein expressed, should and lawfully might make, use, exercise, aud
vend, within. England, Wales, and the Town of Berwick-upon-Tweed, my
Invention of "IMPROVEMENTS IN EXTINGUISHERS TO CANDLES, AND IN THE APPLI-
CATION OF SUCH EXTINGUISHERS TO CANDLES AND CANDLESTICKS;" in which sail
Letters Patent is contained a proviso that I, the said Thomas Walker, shall
cause a particular description of the nature of my said Invention, and in what
manner the same is to be performed,, to be inrolled in His said Majesty's
High Court of Chancery within two calendar months next and immediately
after the date of the said in part recited Letters Patent, as in and by the
same, reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I; the said
Thomas Walker do hereby declare the nature of my said Invention, and the
imanner in which the same is to be carried into effect, are fully described and,

page_text: ascertamed m and by the following desemption thereof, reference being ad
the Drawings hereunto annexed, and to the figures and letters marked
thereon (that is say) :-

My improvements consist in a peculiar arrangement and application of self-
acting extinguishers to such candlesticks as have the candles constantly forced
upwards (as they consume) by springs, the object being to extinguished the
candle in a candlestick at any stated period by bringing a pin in contact with
a catch or stop when the time arrives at which it has been determined the
candle is to be extinguished.
DESCRIPTION OF THE DRAWING.
Figure 1 represents a plan of the extinguisher attached to the cap or nozzle
of a candlestick, as herein-after described. Figure 2 is a section of the candle-
stick and extinguisher, shewing the manner in which it is hinged to the
candlestick. a is the pillar or socket for the candle; 6 the candle within it;
c is the cap or nozzle covering the socket through which the wick of the candle
protrudes. This cover is capable of being removed in order to insert the
candle, it having a suitable slit and pin to retain it when on, or it may be
screwed to the socket. d is the piston on which the candle rests, such piston
being constantly pressed upwards by the spring c, thereby forcing up the candle
as it consumes. f is an axis affixed to uprights on the nozzle, which turns in a
bearing or bearings fixed to the extinguisher. This axis being attached to the
lower end of the extinguisher, as is clearly shown in the Drawing, has a coiled
spring around it, which causes a constant tendency to close the extinguisher
over the candle.
Figure 3 shows a side view of the candlestick with the candle. In this
Figure the manner of retaining the extinguisher back will be more clearly
seen. g is a catch on the lower part of tho extinguisher, and h is a lever
catch turning on a fulcrum at i, by which the extinguisher is held back, as is
shewn in this Figure. j is a slit cut in the socket a, the same having a graduated
scale to denote the quantity of time the candle will burn. k is a pin suspended
by a chain . The object of this pin is to be stuck in the candle according to
the graduated scale to the time required, so that when the candle is consumed
up to that point the pin will come in contact with the lever catch h and release
it from the catch g, the spring will then close the extinguisher over the
candle. Figure 4 is a back elevation shewing the pillar with a back view of
the hinge.
Having thus described the manner of carrying my Invention into effect, I
would remark that I am aware that candlesticks have been before made in

page_text: which the candle is constantly forced upwards by a spring as the candle con-
sumes. I do not, therefore, lay any claim thereto, but confine my claim of
Invention to the construction and application of such self-acting extinguishers
(to candlesticks wherein the candles are constantly pressed upwards by a spring),
as above described and shewn in the Drawing hereunto annexed.
In witness whereof, I, the said Thomas Walker, have hereunto set my
band and seal, this Third day of September, in the year of our Lord
One thousand eight hundred and thirty-five.
