COMPLETE SPECIFICATION.
Improvements in Acetylene Gas Burners.
We, WALTER HENRY DRAKE, of 37, Hathaway Street, Cleveland, in the County
of Cuyahoga and State of Ohio, United States of America, Inventor, and
RUSSELL KNIGHT PELTON, of 91, Norton Street, Cleveland, in the County of
Cuyahoga and State of Ohio, 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:-
-
Our invention relates to the class of burners in which there are two opposing
nipples having openings set at proper angles so that the jets discharged from
them will intersect each other and commingle at the illuminating point.
Its objects are to provide means whereby the nipples may be adjusted toward
or away from each other, and whereby their alignment may be adjusted to the
point of intersection of the jets, and whereby some air may be introduced into
the jets below the lava burner tips through which it passes with the gas and
whereby the flow of gas from the nipples may be regulated at the very point of
discharge so that the flame will not smoke when fed by a reduced current or jet,
and whereby the discharge opening may be pierced by a needle point on the
regulating screw and cleared of any sooty matter or other accumulation of
foreign substances.
The accompanying drawing shows the features of our invention in the form
now considered most desirable by us but, doubtless, changes within the skill
of a good mechanic and not requiring the exercise of invention might be made
in the details thereof without departing from the spirit of our invention as set
forth in the claims at the end of this specification.
Figure 1, is a view in elevation, partly in section, of an acetylene gas burner
with our improvements applied thereto.
Figure 2, is a side elevation thereof.
Figure 3, is a sectional view through one of the nipples taken at a right
angle to the section shown in Figure 1.
Figure 4, represents a modification of one of the features of our invention.
The base or hollow stem, b, of our burner is provided with diverging
branches, d, which are preferably screw-threaded, as shown in Figure 1, to
receive the internally threaded sockets, f, of the nipples, g. The front end of the
chamber in the nipple is preferably conical, as shown, and the exit or discharge
opening,, extends through the end wall to the outer recess, j, in which is seated
the usual lava tip, k, the shank of which extends nearly to the bottom of the
recess.
:
A screw-threaded aperture extends through the back wall of the chamber
and contains an adjusting screw 7, the point or end of which lies in axial line
with and close to the exit opening, h.
The point, p, is sharp and finely tapered and by turning the screw it may be
projected forward into the opening, h, to regulate the flow of gas therethrough
or to entirely close said opening and cut off the flow of gas. By this means

page_text: full pressure of the gas remains throughout the chamber up to the exact point
of exit so that any diminution of the quantity of gas allowed to pass through the
opening does not result in making the flow sluggish. We are therefore enabled
to reduce the flow of gas and obtain a very small flame without producing smoke
and disagreeable odours which arise when acetylene gas is burned with a sluggish
current.
:
The needle point, p, also serves the important purpose of clearing the discharge
opening, h, from any accumulation of sooty or other foreign substances which
might find lodgement in the opening. This we regard as a very important
feature of our invention.
The exit opening, h, discharges directly into the opening in the lava tip, k,
and across the small space at the bottom of the recess, j. Air is admitted to this
space by slots, t, cut through the side walls of the nipple, g, and it is drawn into
the opening in the lava tip by the jet of gas with which it commingles in its
passage through the tip and to the point of combustion.
It will be observed that by screwing the threaded sockets endwise or along
the diverging branches the nipples may be brought more closely together or more
widely separated and that by slightly turning them they may be so adjusted that
their jets will properly intersect and cause a broad fan shaped flame, q, instead of
passing each other as pencil jets."
"
We regard this as another highly important feature of our invention for we
have experienced much trouble with rigid burners of this description in securing
and preserving the perfect alignment necessary to the production of a perfect fan
shaped flame. Burners which are made perfectly true, at the start are, we find,
liable to, warp or spring out of true alignment when heated by the burning gas
and to remain in this condition thereby giving unsatisfactory results.
In Figure 4, we show a modification of the means for adjusting the nipples
in which the hollow diverging branches, d, have plain cylindrical exterior
surfaces, the sockets, f, being bored to fit very snugly upon them and provided
with set screws, y, to secure them in place. We at present however, prefer the
arrangement shown in Figure 1, and illustrate this modification, as one of the
many changes in details which might be made in the burner to accomplish this
and other objects of our invention.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is-
1. In an acetylene gas burner the combination of the hollow standard with
its diverging branches, the nipples with sockets which are mounted on the branches
and capable of endwise and rotary movement thereon substantially as and for
the purpose hereinbefore set forth."
2. In an acetylene gas burner the combination of the hollow standard with its
diverging screw-threaded branches, the nipples with sockets which are screw-
threaded to fit upon the diverging branches substantially as and for the purpose
herein before set forth.
3. In an acetylene gas burner the combination of the nipple with its interior
chamber, suitable connections from said chamber to the source of gas supply,
the exit opening through one end of the chamber and the feed regulating screw
passing through the other end of the chamber in axial line with the exit opening
substantially as and for the purpose herein before set forth.
4. In an acetylene gas burner the combination of the nipple with its interior
chamber connected to a gas supply, an exit opening from one end of the chamber
and the feed regulating screw passing through the other end of the chamber in
axial line with the exit opening, the end of the screw being tapered and needle
pointed to pass into and clear the exit opening if clogged and also to regulate or
stop the flow of gas therethrough substantially as hereinbefore set forth.
5. In an acetylene gas burner the combination of the nipple with its interior

page_text: chamber, the recess at its front end, the exit opening leading from the chamber
to the recess, the lava tip scated in said recess and the side grooves or slots to
admit air to the recess behind the lava tip substantially as hereinbefore set
forth.
