page_text: 1, DANIEL SACKETT MOORE, of 74 East 56th Street, in the City and State of
New York, United States of America, Gentleman, 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 :-
This invention relates to a gas burner of the kind which when turned off still admits
a limited supply of gas sufficient for a minute flame. Thus the burner can be turned
on without the use of a match. The burner is provided with a sliding chimney which
is raised up to surround the small flaine a short time after the main flamo lias been
turned off. In this way the chimney will not be apt to become cracked by the main
flame and will still protect the small flame.
The invention consists in the various features of improvement more fully pointed
out in the claim.
In the accompanying drawing:
Fig. 1 is a front view of my improved burner with the chimney down.
Fig. 2 is a side view thereof with the chimney up.
Fig. 3 is a vertical central section of the burner proper.
Fig. 4 is a section on line x, x, fig. 3.
Fig. 5 is a section on line y, y, fig. 3.
Fig. 6 is a side view of the valve plug showing inlet opening of slit j.
Fig. 7 is a similar view showing the outlet opening of slit j.
The letter a represents the gas inlet pipe entering the valve seat b, from which
projects upwardly the discharge pipe e having the usual tip.
d is the tapering plug valve projecting beyond the valve seat at both ends. These
exposed ends are squared and are embraced by an oscillating frame consisting of
two U-shaped pieces e having laterally projecting arms e¹, and perforated centrally
to fit upon the ends of the plug valve. ff, are chains connected to arms e¹, and
is a pivoted link connecting the oscillating frame to the cap h, carrying chimney i.
By pulling either the chain for the chimney is raised or lowered and at the same
time the plug valve is partially revolved.
g
The plug d is provided with a transverse slit ; connecting the inlet with the
discharge pipe, though intercepted by an axial perforation k. The slit ; should be
j

page_text: long and narrow at its discharge end (see fig. 7) so as to be brought rapidly past the
pipe c, when the plug is turned. The slit serves for the passage of the gas that
supplies the large or main flame. For the auxiliary flame there is a perforation /
smaller than slit and connecting the axial perforation with the surface. Here the
perforation joins a short groove m, partly encircling plug d. The inlet end of slit j
is also connected to an encircling groove n.
When the chain is pulled down the chimney i is lowered and at the same time the
plug d is revolved to bring the slit in line with the pipes a, c, and thus cause a full
supply of gas (fig. 3) for the main flame.
When the chain is subsequently pulled down, the first fraction of rotation of
plug d will bring the slit, past the mouth of pipe e and thereby quickly cut off the
main supply of gas. In order to carry this out, this slit, as before stated should be
long and narrow and the lower end e' of pipe e should also be long and narrow (see
figs. 3, 4 & 5). Thus enough gas can be admitted by these parts to feed the main
flame, and still the main flame can be very quickly cut off. This is necessary because
the main flame should disappear, before the frame e has oscillated sufficiently far, to
raise the chimney up to the flame, for otherwise the chimney would be cracked or
injured by the main flame. The main flame being thus turned off, gas will be fed
through groove n, slit j, central perforation k, perforation and groove m into the
contracted mouth c¹ of pipe c, to supply the auxiliary flame.
i
In order to regulate the size of the auxiliary flame, I make use of a set screw o,
entering axial perforation & and of such a length that it may close up the perforation l,
to a greater or less extent (fig. 3). p is a spring between the oscillating frame and
the plug d for holding the latter tightly to its seat.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
The combination in a gas burner of the pipe a valve seat band pipe c, having long
and narrow slitted mouth c¹ with the valve d having a direct gas passage j, with a
long and narrow discharge end and having an auxiliary gas passage and with an
oscillating frame connected to the chimney cap h and operating the valve substantially
a specified.
