Improvements in Gas Tips or Burners, the same being applicable to
other purposes, such as Spray Nozzles.
I, WILLIAM HENRY PORTER, of Nos. 3-5, West 18th Street, in the City, County
and State of New York, United States of America, Manufacturer, 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 gas tips or burners (or nozzles) and has for its object to
provide an exceedingly simple, cheap and effective burner, (or nozzle) and to these
ends it consists in the various features of construction substantially as hereinafter
more particularly set forth.
In the accompanying drawings:
Figs. 1 to 6 are side views showing different stages of making the tip;
Figs. 1 to 6 are vertical sections of the corresponding figures;
Fig. 7 is a top plan view of the tip on an enlarged scale.
°
Fig. 8 is a sectional view on the line 8-8, Fig. 5, on an enlarged scale looking
upward; and
Figs. 9 and 10 are side views of modified forms of tips.
All the views are enlarged beyond the actual size for purposes of clearness of
illustration.
One of the objects of my present invention is to provide a practicable tip or
burner made from metal, and while, of course, my improved tip may be made in
various ways, so long as it embodies substantially the same features of construction,
I prefer to make it from a thimble of metal in substantially the manner illustrated
and described hereinafter, and while various materials may be used in its construc-
tion it is preferred to make it from aluminium or some similar non-corrosive
material which will not be deleteriously affected by the gas and elements to which
it is exposed.
Heretofore it has generally been the practice to provide tips or burners with two
classes of openings for the passage of the gas, one in the form of a slot extending
transversely across the top of the tip to a greater or less extent, and the other in
the form of two holes usually set opposite to each other, and one of the objects of
my present invention is to provide an improved form of opening for the gas which
is neither a simple slot nor two holes but which may be said to comprise in a
general way a combination of these two forms in that there are practically two
holes connected by an intermediate slot or otherwise expressed a continuous trans-
verse slot having enlargements at its ends. The enlarged portions are arranged at
any desired angle to the connecting transverse slot and preferably extend above
This opening also is preferably formed out of a right line, that is, the
holes or enlarged portions are arranged opposite to each other at a greater or less
angle and extend above the connecting transverse slot. Again the tip is formed
so that the opposed openings or enlarged ends of the slot are in communication with
what may be termed conveying channels extending from the chamber or body of
the tip, and these channels communicate with this chamber at all points through-
the same.

page_text: that other forms may be used in connection with other features of my invention
and the form of gas opening may be used in burners embodying other features
of construction without departing from the spirit of my invention.
Furthermore, while my invention is primarily intended for a gas burner, I have
used the various features for other purposes and do not limit myself to any parti-
cular use.
As an illustration I may mention that the principle of the tip can be applied to
nozzles for liquids or vapors other than gas lighters, the action of the currents
tending to be self regulating, producing an even flow, and in the case of fluids
for instance, producing a fine spray.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
1. A gas tip or burner, or nozzle, the opening of which is in the form of a slot
enlarged at the ends, substantially as described.
2. A gas tip or burner, or nozzle, the opening of which is in the form of a slot
enlarged at the ends, the enlarged portions being in a plane above the central
portion, substantially as described.
3. A gas tip or burner, or nozzle, the opening of which is in the form of a slot
with enlarged ends, the enlarged ends being at an angle to the central portion of
the slot, substantially as described.
4. A gas tip or burner, or nozzle, having a notched portion at its end, the oppo-
site faces of the notched portion having enlarged openings connected by a con-
tracted slot, substantially as described.
5. A gas tip or burner, or nozzle, having a chamber communicating with two
channels throughout their length, the channels terminating in opposed openings,
substantially as described.
G. A gas tip or burner, or nozzle, having two opposed openings at opposite ends
and forming a continuation of an intermediate marrow slot and communicating
with an inner chamber having two channels connecting with said openings, sub-
stantially as described.
7. A gas tip or burner, or nozzle, consisting of a thimble with side indentures
and a transverse gas opening, substantially as described.
8. A gas tip or burner, or nozzle, consisting of a thimble with side indentures,
and a notched portion, the gas opening being formed in the notched portion,
substantially as described.
9. A gas tip or burner, or nozzle, consisting of a thimble with side indentures,
and a notched portion, the gas opening being in the form of a slot enlarged at the
ends and being located in the notched portion, substantially as described.
10. A gas tip or burner, or nozzle, consisting of a metallic thimble having indented
walls a, and a notched end forming a transverse slot with enlarged ends, substan-
tially as described.
