1, ORSON WILLIAMS BENNETT of No. 1503 Pennsylvania Avenue Washington, D.C.
United States of America Inventor, do hereby declare the nature of my 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 improvement in Gas Burners.
It is well known that a considerable percentage of the gas employed as an
illuminating agent is lost by what is commonly termed "blowing" where the gas
escapes under pressure and is consumed rapidly, producing a high degree of heat
And even where the blowing is not
and a consequent low illuminating power.
audible, and the flame remains fairly steady, there is still a great portion of the
flame which burns very pale almost or quite invisible, adding little or nothing to
the illuminating quality of the flame.
It is found however that if the force of the jet issuing from the tip be reduced,
without materially decreasing the supply, the above objectionable features are in a
great degree overcome, and it is further found that by regulating the supply
before it reaches the tip, rather than at the tip a great saving is effected in the
amount of gas wasted and its illuminating power increased.
The object is to provide means for regulating both the quantity of gas which
shall be allowed to escape from the tip and also the force with which it shall
escape.
A further object is to provide means of the above character which shall be capable
of being applied to the great mass of burners now in use as well as to particular
forms either ornamental or plain and which may be furnished at a slight initial
cost.
With these ends in view my invention consists in certain features of construction
and combinations of parts as will be hereinafter described and pointed out in the

page_text: In the accompanying drawings --
Figures 1 and 2 represent respectively an extorior and, longitudinal sectional view
of a burner in which the regulator is applied to a combination or cluster tip.
Figure 3 is a longitudinal section of a burner showing the regulator applied to a
single tip having an expansion chamber.
Figure 4 is a longitudinal section of a burner showing the regulator applied to a
socket at the base of the burner.
Figure 5 is a longitudinal section of a burner showing the regulator applied directly
to a tip of ordinary form.
Figures 6 and 7 represent enlarged sectional views in detail of the ordinary form of
tip and the regulator plug adapted thereto.
•
Figure 8 represents a longitudinal sectional view of a burner in which the regulator
is in two parts and applied to an ordinary tip.
Figure 9 is a view of the tip and the parts of the regulator in detail, shown in
section.
Figures 10, and 11 represent burners in longitudinal section showing different forms
of the regulator sections as applied to the ordinary tip.
Figure 12 represents a burner in longitudinal section showing the English "Bray"
tip provided with the regulator.
Figure 13 is a similar view showing the tip attached to a short pillar by screw_
thread, and
Figure 14 is a longitudinal section of a burner of unusual form showing the
regulator applied to a tubular diaphragm seated within the pillar.
A represents an ordinary pillar of a gas burner such as may be seen in common
use, and a represents the ordinary lava or metallic tip of tubular form, slightly
tapered on its outer surface and provided at its discharge end with a narrow slit a..
Within the pillar and engaged with a tubular part of the burner through which.
the
gas is forced to pass before reaching the discharge opening, an adjustable plug B
. is located.
In the several forms represented by Figures 1, 2, 3, 5, 12 and 13, the plug is shown
engaged directly with the tip proper; in Figures 8, 10 and 11, it is shown engaged
with the tip by means of an intervening tube; in Figure 4 it is shown engaged
with a tube at the base of the pillar, and in Figure 14 it is shown engaged with
a tubular diaphragm seated within the pillar.
The plug B is provided with centripetal passages & leading from its periphery
toward one another, preferably in radial lines, and a passage b' leads from the
adjacent ends of the passages b to the discharge end of the plug. The arrangements
of the gas passages in the plug is quite similar to that shown and described in my
.application filed of even date herewith, viz. 17 December, 1888 No. 18411 but in
my present application said plug is constructed either by an exterior screw thread (}
as shown in Figure 7 or by an interior screw thread C as shown in Figure 9, to be
adjusted relatively to the tubular part of the burner which it immediately engages so
that said tubular part may be made to close and open the outer ends of the centripetal
passages to the entrance of the gas. The end of the plug B toward the gas supply
is constructed to admit gas freely to the outer ends of the passages b, preferably by
being made smaller than the interior of the pillar or tube immediately surrounding the
said end of the plug.
"
In the preferred form of burner shown in Figures 1 and 2 the tip consists of an
enlarged chamber D having a depending tubular projection d adapted to slide or screw
into the top of the pillar A. Under ordinary pressures the frictional contact of the
tubular projection d with the pillar A will be sufficient, but under higher pressure the
screw thread engagement may be desirable.
The chamber D is provided with several openings d' radiating from its interior in
which the ordinary tips a may be secured, producing the cluster or combination tip.
The regulating plug B is engaged with an interior thread in the projection d and
the walls of the latter serve to open or close the openings b in the plug as the latter is
turned in or out of the said projection.

page_text: The tip with its regulator as thus constructed may be applied to the pillars in_com-
non use by simply removing the ordinary tip and inserting it in its place. It may
be removed at pleasure and the regulator turned to admit a greater or lesser quantity
of gas and the gas which is admitted will divide itself by means of the passages b
into opposing currents which will impinge directly against one another as they reach
the axis of the plug, and from that point the gas will pass under reduced speed to the
discharge end of the tip and issue therefrom without blowing" causing a slow com-
bustion and a consequent increased illuminating power.
The form shown in Figure 3 is quite similar in its general characteristics to that
just described, the enlarged chamber being provided with but one discharge opening
instead of several.
In Figure 4 the regulating plug is engaged in the upper end of a tubular section E
at the base of the pillar A, and in Figures and 6 and 7, the said regulator plug is
shown adapted to engage directly the ordinary tip.
In Figures 8 and 9 an intermediate tubular section F interposed between the
ordinary tip and the ordinary pillar is shown, one end of said tubular soction being
fitted to engage the interior wall of the tip and the other to screw within the end of
the plug B closing and opening the passages at their inner ends.
b
Figures 10 and 11 show constructions quite similar in principle to that shown in
Figures 8 and 9 but in these forms the bases of the ordinary tips are fitted within the
ends of the intermediate tubular sections F and in Figure 10, the lower end of the
tubular section F is closed as shown at f
Figures 12 and 13 show the English "Bray" tip provided with the regulator plug
and secured in pillars; in Figure 12, by friction, and in Figure 13 by screw thread.
The burner shown in Figure 14 consists of a pillar A of unusual form within
which a tubular diaphram G is secured preferably by being forced into position by a
sliding movement and held in place by frictional contact with the interior wall of the
pillar. The opening in the dingphraim G has a funnel shaped mouth as shown and the
regulator plug is engaged with the neck of the opening.
The above are some of the various forms in which my invention may be success-
fully and practically applied.
It is evident that many slight changes might be resorted to in the form and arrange-
ments of the several parts described without departing from the spirit and scope of
my invention hence I do not wish to limit myself strictly to the construction herein
set forth, but:-
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed,. 1 declare that what I claim is :-
1st. The combination with a tubular part of a burner, of a gas regulating plug
having a gas passage therethrough, the said regulating plug being engaged with
the tubular part and the tubular part forming a cut-off to open and close the gas
passage through the plug, substantially as set forth.
2nd. The combination with a tubular part of a burner, of a gas regulating plug
having opposing gas passages leading from its periphery toward its axis, and a
passage leading from the opposing passages to the end of the plug, the plug being
engaged with the tubular part and having a movement relatively thereto in the
direction of the axial line, the wall of the tubular part forming a cut-off to open
