PROVISIONAL SPECIFICATION left by the said Edward Thomas Hughes

from abroad by the Benedict and Burnham Manufacturing Company, of Waterbury,
State of Connecticut, United States of America.
This Invention relates to improvements in that class of lamp burners commonly
called "kerosine burners," the object being to produce a burner from very thin
metal, whereby the weight of the burner will be materially diminished.
The Invention consists, first, in forming the chimney holding springs from wire,
with the ends turned to the right and left into substantially the curve of the edge
of the deck, and secured by turning the edge of the deck inward and over the said
projecting ends.
Also in the method of forming the wick and gas tube from a single piece of metal,
whereby a passage for the gas is made outside of and separated from the wisk tube,
as more fully herein-after described.
The general form of the burner does not differ materially from that of burners
heretofore constructed.
.
The deck or chimney rest plate A is made from thin metal, and the edge rolled
over and inward to stiffen the edge of the plate. The chimney springs a are made
from wire, as seen in Fig. 2, doubled downward, the two ends c extending one to the
right and the other to the left, and curved to correspond substantially to the curve
of the deck, and in length, preferably, so that the end of one spring will meet the end
of the next spring, so that the combined extent of these ends will be substantially
the circumference of the deck. Before the deck is turned over the springs are laid

page_text: in place, and then the edge of the deck turned over so as to enclose the ends c of the
spring and firmly hold them in their position. The curve to a great extent prevents
the springs from turning, but the coil at the bottom of the springs extends beneath
the deck plate A, as seen at the right of Fig. 1, so that a further bearing is made to
resist the force outward against the spring. These enclosed ends c greatly strengthen
the edge of the deck or chimney rest, and thereby enable it to be made from very
thin metal. The springs however may be otherwise applied, and a wire enclosed
within the edge of the chinney rest to produce the saine strength.
The wick tube B, shown enlarged in Fig. 3, has combined with it the wick tube b,
making what is known as the Ambrose Patent or gas tube burner. The usual
method of making this tube b has been to. form an independant tube, and set it in
place beside the wick tube. A division between the wick tube and the passage for
the gas is essential.
To make these two parts from one and the same piece, a strip of metal of sufficient
width is bent into the form, starting from one edge e, that edge turned outward
forming a rib f, of the interior depth of the tube, thence around until the metal
comes against the rib e, then turned outward as at g, thence parallel with the
surface of the wick tube, the distance required for the width of the gas tube, when
the other edge of the metal is turned inward, as at h, against the wick tube, thus
completing in one piece the wick tube and the gas tube, with the passage to the
gas tube entirely separated from the wick tube.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Edward Thomas Hughes in the Great Seal Patent Office on the
14th November 1877.

This Invention relates to an improvement in that class of lamp burners commonly
called "kerosine burners," the object being to produce a burner from very thin
metal whereby the weight of the burner will be materially diminished.
The Invention consists, first, in forming the chimney holding springs from wire,
with the ends turned to the right and left into substantially the curve of the edge
of the deck, and secured by turning the edge of the deck inward and over the said
projecting ends.
Also in the method of forming the wick and gas tube from a single piece of metal,
whereby a passage for the gas is made outside of and separated from the wick tube,
as more fully hercin-after described.
The general form of the burner does not differ materially from that of burners
heretofore constructed.
In the accompanying Drawings Fig. 1 is a sectional side view of the burner; Fig.
2, the chimney holder spring detached; Fig. 3, a transverse section through the
wick tube.
The deck or chimney rest plate A is made from thin metal, and the edge rolled
over and inward to stiffen the edge of the plate. The chimney springs a are made
from wire, as seen in Fig. 2, doubled downward, the two ends e extending one to

page_text: the right and the other to the left, and curved to correspond substantially to the
curve of the deck, and in length preferably so that the end of one spring will meet
the end of the next spring, so that the combined extent of these ends will be
substantially the circumference of the deck. Before the deck is turned over, the
springs are laid in place, and then the edge of the deck turned over so as to enclose
the ends c of the spring, and firmly hold them in their position.
The curve to a
great extent prevents the springs from turning, but the coil d at the bottom of the
springs extends beneath the deck plate A, as seen at the right of Fig. 1, so that a
further bearing is made to resist the force outward against the spring. These
enclosed ends c greatly strengthen the edge of the deck or chimney rest, and thereby
enable it to be made from very thin metal. The springs however may be otherwise
applied, and a wire enclosed within the edge of the chimney rest to produce the
same strength.
The wick tube B, shown enlarged in Fig. 3, has combined with it the wick tube b,
making what is known as the Ambrose Patent, or gas tube burner. The usual
method of making this tube has been to form an independent tube and set it in
place beside the wick tube. A division between the wick tube and the passage for
the gas is essential.
To make these two parts from one and the same piece a strip of metal of sufficient
width is bent into the form, starting from one edge e, that edge turned outward
forming a rib f of the interior depth of the tube, thence around until the metal
comes against the rib e, then turned outward as at g, thence parallel with the surface
of the wick tube, the distance required for the width of the gas tube when the other
edge of the metal is turned inward, as at h, against the wick tube, thus completing
in one piece the wick tube and the gas tube, with the passage to the gas tube entirely
separated from the wick tube.
Having now described the nature of the said Invention, I claim,―
First. In a lamp burner, substantially such as described, the deck or chimney
rest constructed with its edge turned inward and enclosing a wire to form
the edge of the chimney rest, substantially as described.
Second. In a lamp burner, substantially such as described, the chimney holding
springs formed from wire, the ends of the said springs turned into a horizontal plane
with the chimney rest and secured thereto by turning the edge of the chimney rest
over the said ends, substantially as described.
Third. In a lamp burner, the combined wick and gas tube, formed complete in a
single piece of metal, with a division between the wick and gas tube, substantially
as described.
In witness whereof, I, the said Edward Thomas Hughes have hereunto set
my hand and scal, this Fourteenth day of November, in the year of our Lord
