AN IMPROVED GOVERNOR FOR REGULATING THE FLOW OF GAS TO BURNERS
Year: 1884

page_text: I THOMAS THORP of Whitefield in the County of Lancaster, Architect do hereby
declare the nature of said Invention for AN IMPROVED GOVERNOR FOR REGULATING
THE FLOW OF GAS TO BURNERS, to be as follows :—
The object of my Invention is to regulate the supply of gas to burners so as to
maintain an equable flow of gas under varying degrees of pressure.
I attain this by using a small metal cylinder open at the lower end and partially
closed by a flange at the upper end: from the centre of this flange rises another
and smaller cylinder having lateral perforations or holes near the bottom end and
closed at the top. A disc is fitted loosely into the interior of the larger cylinder
so as to move freely without friction: from the centre of this disc rises a short tube
of such diameter as to allow it to slide freely in the smaller cylinder also without
friction. This short tube is partially closed by a flange near the upper end and
from the centre of this flange a smaller tube rises. The upper end of the smaller
tube has a rim on the outer side of the same diameter as the short tube.
The above described. parts are then fitted into a metal case made so as to project
slightly into the interior of the larger cylinder and thus forming a seating upon
which the disc rests when no gas is passing to the burner.
When this governor is
applied to ordinary burners which are not intended to be taken to pieces an annular
ring is fitted into the bottom of the interior of the cylinder thus forming a seating
upon which the disc rests. The governor is then inserted into a socket or casing of
brass or other suitable hard metal and a thin metal bush of the same outside
diameter as the larger end of the governor, brought to a feather edge at the lower
end and with an internal screw thread at the upper end is also inserted into the
socket: the feather edge of the metal bush passes between the governor and the
socket and so secures the governor and bush in the socket: any ordinary burner nib.
may then be screwed into the threaded end of the bush which is flush or nearly so
with the top of the socket.
This method of securing governors in sockets may be applied to other forms of
CODANnora

When gas is passing to the burner a portion passes round the edge of the disc
over the flange at the top of the short tube through the lateral holes in the smaller
cylinder and so to the burner.
Another portion of the gas passes up the tube rising from the disc into the
chamber formed between the rim and the top of the smaller cylinder and thus
balances the pressure on the flange on the upper end of the short tube.
The disc and tube being in equilibrium are free to move up and down in the
larger cylinder and when the pressure on the lower surface of the disc exceeds by a
certain amount the pressure on the upper surface, the disc rises and partially closes
the smaller cylinder and thus maintains an equable flow of gas to the burner.

page_text: I, THOMAS THORP of Whitefield in the County of Lancaster, Architect do hereby
declare the nature of my invention for AN IMPROVED. GOVERNOR FOR REGULATING
THE FLOW OF GAS TO BURNERS and in what manner the same is to be performed, :
to be particularly described and ascertained in and by the following statement :-
The object of my Invention is to regulate the supply of gas to burners so as 'to',
maintain an equable flow of gas under varying degrees of pressure.
:
I attain this by using a small metal cylinder open at the lower end and partially,
closed by a flange at the upper end; from the centre of this flange rises another and
smaller cylinder having lateral perforations or holes near the bottom end, and closed
at the top. A disc is fitted loosely into the interior of the larger cylinder so as to
move freely without friction. From the centre of this disc rises a short tube of such
diameter as to allow it to slide freely in the smaller cylinder also without friction."
This short tube is partially closed by a flange near the upper end and from the
centre of this flange a smaller tube rises. The upper end of the smaller tube has a
rim on the outer side of the same diameter as the short tube.
The above described parts are then fitted into a metal case made so as to project
slightly into the interior of the larger cylinder thus forming a seating upon which
the disc rests when no gas is passing to. the burner.
When this governor is applied to ordinary burners which are not intended to be
taken to pieces an annular ring is fitted into the bottom of the interior of the
cylinder thus forming a seating upon which the disc rests. The governor is then
inserted into a socket or casing of brass or other suitable hard metal and a thin
metal bush of the same outside diameter as the larger end of the governor, brought
to a feather edge at the lower end & with an internal screw thread at the upper
end, is also inserted into the socket & so secures the governor & bush in the socket:
Any ordinary burner nib may then be screwed into the threaded end of the bush
which is flush or nearly so with the top of the socket. This method of securing
governors in sockets may be applied to other forms of governors.
When gas is passing to the burner a portion passes round the edge of the disc
over the flange at the top of the short tube through the lateral holes in the smaller
cylinder & so to the burner. Another portion of the gas passes up the tube rising
from the disc into the chamber formed between the rim & the top of the smaller
cylinder & thus balances the pressure on the flange on the upper end of the short
tube. The disc & tube being in equilibrium are free to move up & down in the
larger cylinder, and when the pressure on the lower surface of the disc exceeds, or
tends to exceed by a certain amount the pressure on the upper surface, the disc
rises & partially closes the smaller cylinder and thus maintains an equable flow of gas
to the burner.
And in order that my Invention may be fully understood and readily carried into
effect I will proceed to describe the accompanying sheet of drawings reference being
had to the figures and letters marked thereon.
Fig. 1 is a sectional elevation of my improved governor and case when intended
to be taken to pieces and Fig. 2 is a sectional elevation of my improved governor
and bush for fastening the same into the case or socket when not intended to be
taken to pieces.
Similar letters refer to similar parts in both the views.
In Fig 1 A is a metal cylinder open at the lower end and partially closed by a
flange B at the upper end, C is a smaller cylinder closed at the top & having lateral

diameter as to work without friction in the cylinder C, G is a smaller tube rising
from a flange on F, on this tube is a rim or disc H working without friction in the
cylinder C. In the short tube F may be lateral perforations or holes and a
cylindrical screw I may be fitted for the purpose of covering or uncovering the
lateral holes in the short tube &so adjusting the quantity of gas it is required to
pass, the screw I is also applicable to other forms of disc governors also for the
purpose of adjustment. K is a metallic case in which the governor is inserted
& has a projection or seating L on which the disc rests when little or no gas is
passing.

In Fig 2, instead of the seating on which the disc rests being a part of the case in
which the governor is inserted, an annular ring M is fitted into the bottom of the
cylinder A and a metal bush N screwed at the upper end to receive the nib
& brought to a feather edge at the lower end is pressed between the governor & the
case & serves to secure the governor and the bush into the case; this method of 1
securing governors into cases is also applicable to other forms of governors.
Having now particularly described and ascertained the nature of my said
invention, & in what manner the same is to be performed I declare that what
I claim is
