REPRESENT A CANDLE AND CANDLESTICK, KEEPS THE SURFACE OF A COLUMN OF OIL
CONTAINED THEREIN AT NEARLY AN EQUAL DISTANCE FROM THE BLAZE AS WELL WHEN
A PART OR ALMOST THE WHOLE OF THE SAID OIL IS CONSUMED BY BURNING, AS WHEN
THE INSTRUMENT CONTAINS A FULL QUANTITY, AND DESIGNED TO RENDER THE LIGHT
GIVEN BY OIL STEADY AND EQUABLE, AND AS PORTABLE, CLEANLY, AND ELEGANT AS

FIC.2.A.B.C.D. represents the Inside or Hollow part of a Vessel which on the Outside is variously ornamented according to the size of this part which
Icall the Candlestick or agreeable to the fancy of the Workman. At or near B.C. the foot of the Candlestick is placed when necessary. If the
Gat or Bladder C.C.C. figure 1. is placed in this Candlestick and filled with Oil in such a position that it shall every where exactly touch and
fill the said Candlestick. A.B.C.D. figure 2. the Gallumn of Oil in the Tube A. B. figure 1. will press on the Basis C.D. C.D. and will thereby
keep the Cande buoyed up unless its weight is superior to this pressure. If then the weight of the Tube A.B. is so adjusted that it shall in
this position be equal to the pressure of the Collumn of Oil therein it contained on the Basis Cd. Cd every portion that is taken. from
the Collumn of Oil by Burning will lessen the Buoyant power above mentioned in consequence of which the Candle will sink Inwards until
the Gillumn raises high enough again to support the Candle by its pressure on the Base Cd. Cd. In the meantime as the distance between
the Top of the Cullumn and the moving Base Cd. Cd. is lessen'd every moment as fast as the oil is consumed, the Candlestick which holds
the Gat or Bladder fig 2. is made Conical on the Inside that the Increase of Base may make amends for the Decrease of Collumn. The
Slope represented by A.G.G.E. fig 2. is pritty exactly that which suits the greatest variety of size and fashion. FIG.3. Represents the thing
which holds the Wick and which is placed at the end of the Tabe which represents the Candle. This thing is well known to all Men
and is called a Burner and is used in many common Lamps and therefore unnecessary to describe it. B. The Flexible Vessell and the
application of a power to lessen the Capacity of it as fast as the oil is consumed are the material parts of this Invention
