Improvements in Gas Governors.
I, DAVID BRUCE PEEBLES, of the Tay Works, Bonnington, in the County of
Mid Lothian, North Britain, Gas Engineer, do hereby declare the nature of this
invention to be as follows, that is to say :-
My said invention has for its object to improve and simplify the construction of
gas governors, and comprises a modification for upward flow and suitable for one or
more burners according to size; together with a modification for downward. flow,
and which will allow of the governor parts being removed for examination or other
purpose without disconnecting the pendent gas pipe.
My improved upward flow governor comprises a cylindrical casing up through
which the gas has to pass to the burner or burners, and which is provided with a
screwing-in cover adapted to receive a burner or a pipe leading to one or more
burners. At the upper part of the cylindrical chamber there is held in place by
the cover when screwed in, a disk having a central downwardly projecting nipple
perforated for the gas to pass up through it. The disk is also formed with three
or other suitable number of depressions or points projecting down exactly to the
same extent as the central nipple. Beneath the disk held as described there is a
floating disk fitting the cylindrical chamber but loose enough to move up and down
freely, and this disk has small holes for the passage of the gas through it of suitable
sizes. It has also a very small hole at its centre so that some gas may pass through
the nipple of the upper fixed disk even when the floating disk is close up to the
nipple. The gas from the bottom inlet bears up the floating disk in a manner to
make it close the nipple opening more or less accordingly as the pressure is greater
or less. Above the fixed disk there is held a dome-shaped shell made with one or
more lateral slits or openings, such shell preventing the issuing gas from making
a noise.
In the modification for downward flow there is a cylindrical chamber having in
it a floating disk and the inlet gas has access to the space below the floating disk.
The inlet gas has also access, through a passage which can be regulated by a screw,
to the upper side of the floating disk, whence it finds its way by lateral openings
into a tube fixed centrally to the floating disk. The tube the bottom of which is
closed extends up through a central hole in the top of the chamber, and when in
its highest position, its upper end which is open closes up against a horizontal
surface. These governor details are formed and contained in a piece, made with
outer ground conical parts fitting tightly in a ground conical socket formed in a
vertical body piece which has its upper end adapted for being fixed to the upper
part of a pendent gas pipe, its lower end being adapted for having fixed to it a
continuation of the gas pipe. The governor piece is made with external depressions
which when the piece is fixed in the body piece form passages from the inlet to the
governor and from the governor to the outlet; and it is an advantageous feature
of the construction that the passage for the gas through the governor is very short.
The governor piece can be fixed in the body piece with a single screw; and it may
be made with a projection to take hold of to facilitate its removal. The governor
piece and if necessary the body piece may be modified as regards the internal
passages in a manner to allow of the body piece being horizontal or inclined.

I, DAVID BRUCE PEEBLES, of the Tay Works, Bonnington, in the County of
Mid Lothian, North Britain, Gas Engineer, 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, that is to say :-
My said invention has for its object to improve and simplify the construction of
gas governors, and comprises modifications for upward flow and suitable for one or
more burners according to size; together with a modification for downward flow,
and which will allow of the governor parts being removed for examination or other
purpose without disconnecting the pendent or other gas pipe.
My improved upward-flow governor comprises a cylindrical casing adapted to
receive a burner or burners and to contain a fixed disk with nipples one or more of
which are perforated for the gas to pass through them. Beneath the fixed disk
there is a floating disk with small holes through it one being opposite a central
nipple. The gas from the bottom inlet bears up the floating disk in a manner to
make it close the nipple openings more or less accordingly as the pressure is
'greater or less.
The downward-flow governor comprises a cylindrical chamber having in it a
floating disk, to the lower and upper sides of which the inlet gas has access. From
the upper side of the disk the gas finds its way into a tube fixed centrally in the
disk, and arranged to close up against a horizontal surface when in its highest
position. These governor details are formed and contained in a piece fitting in a
socket formed in a body piece. The governor piece is made with external
depressions which when the piece is fixed in the body piece form passages from the
inlet to the governor and from the governor to the outlet.
And in order that my said invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings,
to be hereinafter referred to, and showing four modifications of my improved gas
governors.
Figures, 1, 2, and 3, of the drawings are respectively enlarged vertical sections
of three modifications.
Figures, 4, and 5, are enlarged vertical sections, as taken at right angles to each
other, and
Figure, 6, is an enlarged horizontal section of a fourth modification.
In Figure, 5, some parts are omitted for the sake of clearness.
In these drawings the same reference letters and numerals are used to mark the
same or like parts wherever they are repeated.
My improved upward-flow governor shown in Figure, 1, comprises a cylindrical
chamber, A, up through which the gas has to pass to the burner, B, and which is
provided with a screwing-in cover, C, adapted to receive the burner or it might be
a pipe leading to one or more burners. At the upper part of the cylindrical
chamber, A, there is, held in place by the cover, C, when screwed in a disk, D,
having a central downwardly projecting nipple, F, perforated for the gas to pass up
through it. The disk, D, is also formed with three or more other nipples, or
depressions or points, G, projecting down exactly to the same extent as the central
nipple, F, and being by preference similarly perforated. Beneath the disk, D,
held as described, there is a floating disk, H, fitting the cylindrical chamber, A,
but loose enough to move up and down freely and this disk has small holes, J, for
the passage of the gas through it of suitable sizes. It has also a very small hole, K,
at its centre so that some gas may pass through the central nipple, F, of the upper
fixed disk, D, even when the floating disk, H, is close up to the nipple. The gas

page_text: from the bottom inlet, L, which is screwed externally, bears up the floating disk, H,
in a manner to make it close the nipple openings, F, and, G, more or less accordingly
as the pressure is greater or less. Above the fixed disk, D, there is held a dome-
shaped shell, M, made with one or more lateral slits or openings, N.
In the modification shown in Figure, 2, which is also for an upward flow of gas,
the cylindrical chamber, A, is contained in another casing, P, large enough to leave
an annular passage, Q, between it and the chamber. The chamber, A, is fixed. by
having its bottom part screwed into the bottom inlet, L, of the casing, P, into the
upper part of which also the cover, C, is screwed so as to hold the disk, D, in
place. The gas enters by the bottom inlet, L, and acts on the floating disk, H, as
hereinbefore described and it also enters the annular space, Q, by one or more
lateral openings, R, in the chamber, A, beneath the disk, whence it has access to
the nipple openings, F, and, G, by a lateral opening, S, in the upper part of the
cylindrical chamber, this opening being controllable by a screw plug, T.
In the modification shown in Figure, 3, the cylindrical chamber, A, is formed in
a casing, which is elongated and the entrance and exit passages for the gas are
horizontal. The gas enters by the inlet, L, which in this case is divided by a
partition, L 1, the lower passage leading to the space beneath the floating disk, H,
whilst the upper passage leads by an opening, S, controllable by a screw plug, T,
to the space between the disks, Ď, and, H.
In the modification for downward flow, shown in Figures, 4, 5, and, 6, there is a
cylindrical chamber, A having in it a floating disk, H, and the inlet gas has access
by the passage, L, and the hole, L2, to the space below the floating disk. The
inlet gas has also access by the passage, L, and hole, S, which can be regulated by
a screw plug, T, to the upper side of the floating disk, H, whence it finds its way
by lateral openings, H 1, into a tube, H 2, fixed centrally to the floating disk, H.
The tube, H 2, the bottom of which is closed extends up through a central hole in
the top of the chamber, A, and when in its highest position, its upper end, which
open, closes up against a horizontal surface, H 3. The bottom of the chamber, A,
is closed by a screw plug, H 4. These governor details are formed and contained
in a piece, V, made with outer ground conical parts fitting tightly in a ground
conical socket formed in a vertical body piece, P, which has its upper end adapted
for being fixed to the upper part of a pendent gas pipe, its lower end being adapted
for having fixed to it a continuation of the gas pipe. The governor piece, V, is
made with external depressions which when the piece is fixed in the body piece, P,
form passages, Q, from the inlet, L, to the governor, and from the governor to the
outlet, Q1, and it is an advantageous feature of the construction that the passage
for the gas through the governor is very short. The governor piece, V, can be
fixed in the body piece, P, with a single screw, V 1; and it may be made with a
projection, V 2, to take hold of to facilitate its removal. The governor piece, V,
and if necessary the body piece, P, may be modified as regards the internal
passages to allow of the body piece being horizontal or inclined.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. Constructing and combining the parts of upward-flow gas governors in the
improved manner substantially as hereinbefore described with reference to Figure, 1,
of the accompanying drawings.
2. Constructing and combining the parts of upward-flow gas governors in the

4. In gas governors of the kind to which Claims, 1, 2, and, 3, relate, the
combination of an upper fixed disk having downwardly projecting nipples one or

page_text: more of the nipples being perforated, with a lower floating disk arranged and
operating substantially as hereinbefore described.
5. Constructing and combining the parts of downward-flow gas governors in the
improved manner substantially as hereinbefore described with reference to
Figures, 4, 5, and, 6, of the accompanying drawings.
6. For a downward-flow gas governor, forming and fitting the governing parts in
a piece fitting tightly in a ground conical socket in a body piece constructed for
being connected to the supply and continuation pipes, the governor piece being thus
removable without disconnecting the pipes, substantially as hereinbefore described.
