An Improved Gas-burner.
WILLIAM BUIST PICKEN Artist 35 Agamemnon Road West Hampstead
London N.W. do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved gas-burner of the type known as "fish-tail,"
or "union jet." The body of my burner is cone-shaped, or it may be hemi-spherical.
In the centre of the flat surface of the cone, or of the (approximate) hemi-sphere,
a single basin is hollowed out, this concavity forming a certain part of a hollow
sphere of known diameter. The width of the basin varies with the size of the
burner-i.e., with the burner as made for a given size of flame at a standard
pressure but the basin for each size of burner is only wide enough to contain
within it the elliptical openings.
In
The passages for the converging streams of gas are not bored as hitherto. The
ordinary elliptical openings into the basin I cause to intersect at a definite angle
and to a fixed degree; and instead of the passages from these egress openings to
their ingress ends following the same lines so that the major and minor diameters
of ingress and egress openings would be in the same directions, I so drill the
passages that the ingress major diameters are transverse to those of the egress.
no case do I make the ingress vertical diameter greater than the ingress horizontal
but from equal ingress diameters I vary the major degree of the horizontal
(according to varying requirements) until it corresponds in form to what if
projected on a plane surface would be a full ellipse transverse to the basin or
egress ellipse.
one,
Whether this burner be used with or without a governor, instead of the usual
"regulator," or "distributor," of slight and approximately equal density for all
sizes, I employ a diffuser of much greater retarding and diffusing power, varying
the degree of this power with the size of the burner, according to the following
formula: For each size of burner a diffuser of the maximum density that will pass
at low pressure the required amount of gas for the burner to attain its highest
illuminating power at the lowest relative expenditure of gas.

London N.W. do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
My invention relates to an improved gas-burner of the type known as
or " union jet."
"fish-tail"
The body of my burner (i.e. of the burner-tip) is cone-shaped, or it may be
approximately hemi-spherical. In the centre of the flat surface of the cone, or of
the approximate hemisphere, a basin is hollowed out, this concavity being spherically

page_text: symmetrical like part of a hollow sphere. The diameter of the basin varies with
the size of the burner, i.e, with the burner as bored for different sizes of flames at
a standard pressure-but the basin for each size of burner is only wide enough to
contain within it the elliptical openings to be described. The passages for the
converging streams of gas into the basin are not bored as hitherto. Instead of the
elliptical openings into the basin meeting as in other burner-tips of this type, I
cause them to intersect at a definite angle to a considerable degree, and instead of
the passages from these egress openings to their ingress ends following the same
lines so that the major and minor diameters of ingress and egress openings would
be in the same directions, I so drill the passages that the ingress major diameters
are transverse to those of the egress. In no case do I make the ingress vertical
diameter greater than the ingress horizontal one, but from the circular I vary the
degree of major horizontal diameter (according to varying requirements) until it
corresponds in form to that which, if projected on a plane surface, would be a full
ellipse, transverse to the basin or egress ellipse, the transverse diameters being
graduated along the passages into each other.
Fig. 1. is a sectional elevation of a cone-shaped tip, showing basin and gas-
passages A, basin; B B, egress ends of gas-passages; C C, ingress ends of
same.
:
Fig. 2. is an elevation showing ingress ellipse, C', transverse to the egress
ellipses.
Figs. 3. and 4. are same as Figs. 1. and 2., but relating to the approximately
hemi-spherical tip.
Fig. 5. is a plan of either cone or hemi-spherical tip, showing basin and egress
ellipses, with the intersection of the latter :-A, basin; B B, egress ellipses
(transverse to the ingress ellipses, C C,); D, intersection of ellipses.
The drawings are on an enlarged scale, approximately six times the actual size.
When the burner-tip is used without a governor, instead of the usual "regulator"
or "distributor" of slight and approximately equal density for all sizes, I employ
a diffuser of much greater power, varying the degree of this power with the size of
burner, according to the following formula :-For each size of burner, a diffuser of
the maximum density that will pass at low pressure the required amount of gas.
The burner case I make as usual.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
-
That the novel features of my invention are-
1. The form of the gas passages with their ingress and egress ellipses transverse
to each other, giving a composition of forces yielding a superior flame.
2. The drilling of the egress ellipses quite close to the rim of the basin, instead
of with the usual space between them and the rim.
3. The intersection of the egress ellipses as described, and in the form of basin
already described, in such manner and degree that the line of intersection, when
viewed perpendicularly, will appear almost straight, and in size about one-third the
length of the major diameter of the egress ellipse.
