being date of first Foreign Application 2nd Dec., 1898
(in United States),
I, ARTHUR KITSON, of 1,050, Drexel Buildings, Philadelphia; in the County of
and State of Pennsylvania, United States of America, Civil Engineer, do hereby
declare the nature of this invention to be as follows:
This invention relates to improvements in vapour burning apparatus and more
particularly consists in an improved form of vapour tube cleaner for keeping the
discharge opening of the vaporizing tubes used in such apparatus free from carbon
and other impurities, which tend to collect therein and interfere with the dis-
charge of vapour.
The invention is particularly applicable to that kind of vapour burning
apparatus in which the vapour is discharged from a tube having an orifice flaring
outwardly so that the apex of the cone is pointing toward the axis of the tube
and the base of the cone extends to the wall of the tube. This kind of opening
is most generally formed by punching up a portion of the said wall of the tube.
The needle is mounted opposite said discharge opening and provided with means
for projecting it into said opening and alternately withdrawing it therefrom
and to one side of the line of discharge.
The preferred form of means for moving the needle consists of a parallel
motion mechanism or frame on which the needle is mounted. This frame is
carried by two sets of swinging arms which are pivoted to a bed piece. This
bed piece, and consequently the whole parallel motion mechanism or other form
of hinged frame, is removably mounted on the vapourizing apparatus by means
of a spring hook-shaped projection which slips over the mouth of the mixing
tube. The upper swinging piece may be made solid or might be made U-shaped,
the lower swinging piece however, being in such position that it falls below the
vaporizing tube, must be made U-shaped. This lower piece is pivoted on
the foundation piece by a pin, and the upper piece is similarly pivoted by a
pin or shaft which latter is rigidly connected with the latter piece by means of
a short cross pin or some other similar device.
The parallel moving piece is also made double to encompass the vaporizing
tube, and is composed of two parallel portions or side pieces connected at the

page_text: bottom. Various means for giving vibrating motion to the swinging frame
could be used, but I prefer the pivoted shaft of one of the pieces extended and
a reversing lever mounted thereon. From either end of this reversing lever
pendants in the form of. chains or cords may be suspended to afford convenient
means for moving the lever. Springs or weights may also be employed for
returning the needle to its original position after the power which forces it into
the needle hole has been removed.
The method of operating the invention is evident from the foregoing.
By pulling one of the pendants until the reversing lever reaches the limit of
its motion, the frame and needle will be thrust down out of the way of the
issuing jet of vapour: By pulling on the 'other pendant until the lever reaches
its extreme limit of motion in the other direction, the needle will be inserted
in the discharge opening and any impurities collected therein, forced back out
of the way. By alternately pulling the pendants several times, so as to move
the reversing lever to and from the horizontal position, the cleaning of the
discharge opening can be thoroughly done. One of the pendants is then given
a final pull, throwing the needle down into the lowermost position, and the lamp
can proceed in its operation without being interfered with by the needle.
It is evident of course that various changes could be made in the details of the
apparatus above described without departing from the spirit and scope of
my invention so long as the principle of operation set out in the specification is
preserved. Other means than the positive pull by the operator might be
employed to move the needle in and out; other means of guiding the needle to
and from the opening might be employed, and various modifications be made to
adapt the cleaner to different styles of lamp, but all these I consider within the
limit of the invention.

Improvements in and relating to Vapour Burning Apparatus.
I, ARTHUR KITSON, of 1,050, Drexel Buildings, Philadelphia, in the County of
and State of Pennsylvania, United States of America, Civil Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:
This invention relates to vapour-burning apparatus and more particularly
consists in an improved form of vapour-tube cleaner for keeping the discharge-
opening of the vaporizing tube used in such apparatus free from carbon and
other impurities, which tend to collect therein and interfere with the discharge
of vapour..

In order that the nature of the invention and the manner of performing the
same may be well understood, reference will be made in the following descrip-
tion thereof to the ammpanying drawings, in which Fig. 1 is a side elevation
of a vapour-burning apparatus such as described and shown in the Specification
of Letters Patent numbered 22204 of 1898, with the muffler in section and pro-
vided with an example of a vapour tube cleaner according to this invention;
Figs. 2 and 3 are drawn to a larger scale than Fig. 1 and show two central
sections of the mixing tube at right-angles to each other; the vapour-tube

leaner being shown respectively in section and in elevation; Fig. 4 is a side
levation corresponding to Fig. 2 and showing the reversing lever in various
positions; Fig. 5 is a plan corresponding to Fig. 3; and Fig. 6 shows the
nixing tube and the vapour-tube cleaner in section according to the line VI
of Fig. 2.
The invention is particularly applicable to that kind of vapour-burning
apparatus (an example of which is shown and marked 1 in Fig. 1) in which
the vapour is discharged from a tube 2 having an orifice 3 flaring outwardly
and in the form of a cone whose apex points toward the axis of the tube and
whose base extends to the wall of the tube. This kind of opening is most
generally formed by punching up a portion of the said wall of the tube. Oppo-
site to the discharge opening 3 there is mounted a needle 4 which is provided
with means for alternately projecting it into the said opening and withdrawing.
it therefrom and to one side of the line of discharge.
The means for moving the needle 4 consists, in the example shown, of a
parallel-motion mechanism or frame 5 on which the needle is mounted. This
frame is carried by two sets of swinging arms 6 and 7 which are pivoted to a
bed piece 8. This bed piece, and consequently the whole parallel-motion
mechanism or other form of hinged frame, is removably mounted on the
vaporizing apparatus by means of a spring hook-shaped projection 9 which slips
over the mouth of the mixing tube 10. The upper swinging piece 7 may be
made solid, as shown, or might be made U-shaped; the lower swinging piece. 6,
however, being in such a position that it falls below the vaporizing tube 2.
The lower piece 6 is mounted
must be made U-shaped, as shown in Fig. 6.
on the bed piece 8 by means of a pin 15, and the upper piece 7 is similarly
mounted by means of a pin or shaft 11, which is rigidly connected with the
piece 7 by means of a short cross pin 16 (Figs. 2, 3, and 5) or some other
similar device. The parallel moving piece is also made double to encompass
the vaporizing tube 2, and is composed of two parallel portions or side pieces
connected at the bottom, as shown in Figs. 3 and 6. Various means for giving
vibrating motion to the swinging frame could be used, but I have shown the
pivotal shaft 11 of the piece 7 extended and a reversing lever 12 mounted
thereon. From the two ends of this reversing lever pendants in the form of
chains or cords 13 and 14 may be suspended to afford convenient means for
moving the lever.
By
The method of operating the cleaner is evident from the foregoing.
pulling the pendant 14 until the reversing lever 12 reaches the limit of its move-
ment (indicated by dotted lines in Fig. 4) the frame 5 and the needle 4 will
be thrust down out of the way of the issuing jet of vapour, and the needle 3
will be caused to assume the position indicated by dotted lines in Fig. 2. By
pulling the other pendant 13 until the lever reaches its extreme limit of move-
ment in the other direction (also indicated by dotted lines in Fig. 4), the
needle 4 will be inserted into the discharge opening 3 and any impurities
collected therein will be forced back out of the way. By alternately pulling the
pendants 13 and 14 several times, so as to move the reversing lever 12 to and
from the horizontal position last mentioned, the cleaning of the discharge open-
ing can be thoroughly done. The pendant 14 is then given a final pull, throwing
the needle down into its lowest position, so that the lamp can proceed in its
operation without being interfered with by the needle.
It is evident of course that various changes could be made in the details of the
apparatus herein before described without departing from the spirit and scope of
the invention so long as the relative arrangement of the parts shown in the
drawings and the principle of operation set out in the specification is preserved.
Other means than the positive pull by the operator might be employed to move
5 the needle in and out, other means of guiding the needle to and from the opening
might be employed, and various, modifications be made to adapt the cleaner to
different styles of lamps, but all these I consider within the limit of the invention.
