I, DAVID BRUCE PEEBLES, of the Tay Works, Bonnington, in the County of
Mid Lothian, North Britain, 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:-
My said Invention has for its object to improve the construction and action of
apparatus for governing or regulating the flow or pressure of illuminating gas, and
comprises modifications suitable for a downward flow of the gas and others suitable
for an upward flow.
Apparatus made according to my Invention is shown upon an accompanying sheet
of explanatory drawings, figures, 1 to 4, of which are vertical sections of modifications
of my improved governor, whilst figure, 5, is an elevation. Figures 6, and 7, are an
elevation and a horizontal section of a holder in which the governor may be secured.
In these drawings the same reference numerals are used to mark the same or like
parts wherever they are repeated.
In the modification shown in figure, 1, and which is designed for a downward flow,
the, gas inlet, 8, at the top communicates by a side port, 9, the effective opening of
which can be adjusted by a plug, 10, screwed in from the opposite side, with a
passage, 11, leading down into a cylindrical chamber, 12, which has in it a conical or
flat piston, 13, of thin metal and by preference made with a cylindrical flange or rim.
A tube, 14, formed centrally on the upper side of the piston, 13, works up into a
central passage, 15. in the top of the cylindrical chamber, 12, and the full inlet
pressure has access through the tube to the under side of the piston. The governor
casing or box is formed in two parts, the top being screwed into the lower part; and
the chamber, 12, is formed in the top part and so as to project down into the lower

page_text: part with an annular space round it. The bottom of the chamber, 12, is closed by a
rimmed disk, 16, and there is no current through the central tube, 14. The gas
passing through the adjusted port, 9, has access to the upper side of the piston, 13,
but acts on it with less than the inlet pressure owing to the contraction of the port, 9;
and it passes from the chamber, 12, by one or more lateral openings, 17, into an
annular passage, 18, and thence through notches in the rim of the bottom disk into
the outlet passage, 19, leading to the burner. When the inlet pressure varies the
piston, 13, rises or falls and correspondingly alters the area of the openings, 17, in the
side of the chamber, 12, so as to maintain a practically uniform flow and pressure of
gas through the outlet and burner.
In the second modification shown in figure, 2, and also arranged for a downward
flow, a central tube, 20, fixed and projecting down from the top of the chamber, 12,
passes through the centre of the piston, 13, which works up and down on it.
In a third modification shown in figure, 3, and also arranged for downward flow,
the piston, 13, is made with a tube, 14, working on the outside, or it might be on the
inside of the fixed tube, 20.
In a modification shown in figure, 4, and which is suitable for an upward flow, the
piston, 13, made with a central tube, 14, projecting up from it works in a cylindrical
chamber, 21, formed in a separate piece from the outer casing of the apparatus. The
full pressure from the inlet, 22, has access to the under side of the piston, 13; and
the gas for consumption passes into a lateral passage, 23, through a port, 9, regulated
by a plug, 10, screwed from the opposite side. The chamber, 21, is placed
eccentrically in the casing and the gas has access by the lateral passage, 23, to the
space at one side of it and thence through one or more holes into the interior of it
above the piston, 13. The piston tube, 14, is closed at its bottom and has a lateral hole
above the piston, 13, to admit the gas from the space above the piston. The top of
the tube, 14, works up through an opening in the top of the chamber, 21, and more or
less approaches a cap, 24, made with lateral openings into the outlet, 25. The passage
of the gas from under the cap, 24, is diminished or increased accordingly as variations
in the inlet pressure makes the top of the tube, 14, move nearer to or further from
the under side of the cap.
I provide for the governor being conveniently removed for examination, repair, or
cleaning, without detaching or interfering with any part of the gas fittings between
the governor and burner, by placing it in a metal frame, 26, figures, 6, and 7, made
with screwed sockets, 27, for permanent, attachment in the line of gas pipe, 28,
(whether descending or ascending). Inside of the top and bottom members of the
frame, 26, recessed seats are formed to receive top and bottom nozzles, 29, 30, formed
on the governor, 31. Rings or coils of rubber, or asbestos, or other suitable
compressible material are placed on the governor nozzles, 29, 30; and the governor
being placed in the frame, 26, is secured by cap bars, 32, made with semi-annular
parts and which being forced against the compressible rings and being held in position
by screws form gas-tight joints.
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 I am aware
of the specifications numbered 3623 of 1886 and 16817 of 1887 and I desire
it to be understood that I do not claim anything covered or claimed thereby, but
what I claim is :-
1. Constructing or combining together the parts of gas governors for downward
flow substantially in the improved manner hereinbefore described, and as shown in
figures, 1, 2, and 3, of the accompanying drawings.
2. Constructing the chamber, 12, in the top piece of the casing or box, and closing
its bottom with a disk, 16, made with a rim which is notched for the passage of gas
to the outlet substantially as hereinbefore described with reference to figure, 1, of the
accompanying drawings.
3. Constructing or combining together the parts of gas governors for upward flow

page_text: substantially in the improved manner hereinbefore described and as shown in figure, 4,
of the accompanying drawings.
4. Constructing the chamber, 21, in a separate piece and placing it eccentrically in
the casing as hereinbefore described with reference to figure, 4, of the accompanying
drawings.
5. Securing a gas governor in a frame or holder forming a permanent part of the
gas fittings in a manner admitting of the removal of the governor without disturbing
any part between the governor and burner, substantially in the improved manner
hereinbefore described.

.
Apparatus made according to my Invention is shown upon an accompanying sheet
of explanatory drawings, figures, 1 to 4, of which are vertical sections of modifications
of my improved governor, whilst figure, 5, is an elevation. Figures 6, and 7, are an
elevation and a horizontal section of a holder in which the governor may be secured.
In these drawings the same reference numerals are used to mark the same or like
parts wherever they are repeated.
In the modification shown in figure, 1, and which is designed for a downward flow,
the gas inlet, 8, at the top communicates by a side port, 9, the effective opening of

chamber, 21, formed in a separate piece from the outer casing of the apparatus. The
full pressure from the inlet, 22, has access to the under side of the piston, 13; and
the gas for consumption passes into a lateral passage, 23, through a port, 9, regulated

the tube, 14, works up through an opening in the top of the chamber, 21, and more or

of the gas from under the cap, 24, is diminished or increased accordingly as variations
in the inlet pressure makes the top of the tube, 14, move nearer to or further from
the under side of the cap.
I provide for the governor being conveniently removed for examination, repair, or
