Garside, Engineer, both of Halifax, in the County of York, for the Invention of
"IMPROVEMENTS IN APPARATUS EMPLOYED FOR REGULATING THE ADMISSION
AND CONDUCTING OF AIR INTO STEAM BOILER OR OTHER FURNACES."
PROVISIONAL SPECIFICATION left by the said Joseph Waddington and
Walker Garside at the Office of the Commissioners of Patents on the 8th March
1876.

FOR REGULATING THE ADMISSION AND CONDUCTING OF AIR INTO STEAM BOILER
OR OTHER FURNACES."
This Invention relates to and is an improvement in the construction of valves and
the frames or boxes in which they hang in equilibrium or are hinged on centres or
axes horizontally, for which Letters Patent were granted to Charles Gall, dated the
Fifteenth day of February, One thousand eight hundred and sixty-six, Number 487
(now void), and for which Letters Patent were granted to the said Charles Gall,
dated the Twenty-sixth day of July, One thousand eight hundred and seventy,
Number 2009, in both the Specifications of which is described and shewn by
Drawings a valve or door hinged under the fire bridge (at the back of the ashes
place), which is connected by rods and levers with the furnace door, so that when it
is opened the said valve will also be opened.
In the latter Specification is described (and shewn by Drawings) a valve door or
hollow plate, with a partition therein of a V form or an angular or zig-zag line to
divide the interior into two compartments, and which partition has a small perfo-
ration at the angle or other suitable part, also a larger one at each end, and it is
through one or other or both of these larger-openings that the quicksilver or other
matters with which the interior of the valve is supplied has to pass to the other side
of the rib in closing or operating the fire door..
Now we construct our valve door or hollow plate (which we propose to place
under the fire bridge in a suitable frame or box constructed as hereafter described)
with four compartments, two of which are supplied with quicksilver or other
matters; we have four ribs or partitions, which are connected in the centre by a
[Price 6d.]

page_text: connecting piece, through which is made a hole or perforation at the bottom part,
and the said hole we make V shape by preference, but any other form will answer,
and a ball or plug is so placed in the interior of one of the spaces or compartments
that it will move backwards and forwards therein and regulate the flow of the
quicksilver or other matters in passing through the hole or perforation in the con-
necting piece, which quicksilver or other matters causes the valve to turn self-actingly
upon its own axes, and gradually close the opening in the box or frame in which
it works. The valve is first set in motion or operated upon by means of a rod and
pin which takes into the arms of a wheel secured on one of the axis of the valve.
We dispense entirely with the larger openings, which are described and shewn on
the Drawings of the said Specification, Number 2099, as M, and the quicksilver or
other matters, when the valve is turned so as to be ready to close the opening again
as required, passes back through the same hole in the connecting piece, the ball or
plug moving sufficiently clear of the same to allow a free passage for its exit from
one compartment to the other; and it will be seen that by this means any dirt,
sand, or sediment which might have accumulated at the entrance of the hole will
be washed or forced back on the return of the quicksilver or other matters, whereas
in the case where the quicksilver or other inatters has to return by other openings
such is not the case, and in practice it is found that the hole or aperture through
which it ought to pass becomes plugged up, and so the desired action of the valve
is prevented. We form a groove or channel for the ball or plug before described to
work or move in, and provide a stop or guard picce to prevent it moving or travelling
too far away from the hole or aperture in the connecting piece. We construct the
box or frame in which the said valve hangs in equilibrium or is hinged on centres
horizontally in an elongated form, so that it is continued forward past the brick-
work of the bridge or place in which it is fixed, and we have an enlarged circular
(by preference) or other form of top, with elongated or other form of perforations
made therein, which equally distribute the current of air admitted by the valve and
contained therein amongst the smoke or other products of combustion. By this
construction of box or frame no ashes, "hardirons," or refuse can get (as by the
heretofore employed frame or box) into the portion where the valve works, and so
the valve can always move freely within, and also acts as a greater conductor and
distributor of the air in the required place, and we make provision by a space
constructed on the top side for any ashes or refuse falling on the frame or box to
pass out at the end into the bottom of the flue apart or away from the box, and to
prevent the admission of air through the space we hinge thereto a door of sheet
iron or other light metal.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Joseph Waddington and Walker Garside in the Great Seal Patent
Office on the 6th September 1876.

OR OTHER FURNACES."
This Invention relates to and is an improvement in the construction of valves and
the frames or boxes in which they hang in equilibrium or are hinged on centres or
axes horizontally, for which Letters Patent were granted to Charles Gall, dated the
Fifteenth day of February One thousand eight hundred and sixty-six, Number 487
(now void), and for which Letters Patent were granted to the said Charles Gall,
dated the Twenty-sixth day of July One thousand eight hundred and seventy,
Number 2099, in both the Specifications of which is described and shewn by
Drawings a valve or door hinged under the fire bridge (at the back of the ashes
place), which is connected by rods and levers with the furnace door, so that when it
is open the said valve will also be opened.

page_text: In the latter Specification described (and shewn by Drawings) a valve door or
hollow plate with a partition therein of a V form or an angular or zig-zag line to
divide the interior into two compartments, and which partition has a small per-
foration at the angle or other suitable part, also a larger one at each end, and it is
through one or other or both of these larger openings that the quicksilver or other
matters with which the interior of the valve is supplied has to pass to the other side
of the rib in closing or operating the fire door.
Now we construct our valve A, of which Figs. 1 and 2 are enlarged views, and
which we place under the fire bridge B, in a suitable frame or box C constructed as
hereafter described. The said valve we make with four compartments in the in-
terior, two of which are supplied with quicksilver or other matters, we have four ribs
or partitions D which are connected in the centre by a connecting piece E, through
which is made a hole or perforation at the bottom part, and the said hole we make
V shape by preference, but any other form will answer, and a ball e, as shown in
Fig. 1, or plug f, as shewn in Fig. 2, is so placed in the interior of one of the spaces or
compartments that it will move backwards and forwards therein and regulate the
flow of the quicksilver or other matters in passing through the hole or perforation
in the connecting piece, which quicksilver or other matters causes the valve to turn
self-actingly upon its own axes, and gradually close the opening in the box or frame
in which it works. The valve is first set in motion or operated upon by means of a
rod F and a pin which may take into the arms of a wheel which may be secured on
one of the axes of the valve, but we prefer to cast a piece G on the valve and make
a suitable opening therein, as shewn more clearly in full size end view of valve at
Fig. 6, Sheet 2, the pin g taking into this opening and operating the valve as
required.
We dispense entirely with the larger openings, which are described and shewn on
the Drawings of the said Specification, Number 2099, as M and the quicksilver or
other matters when the valve is turned so as to be ready to close the opening again
as required, passes back through the same hole in the connecting piece, the ball e or
plug moving sufficiently clear of the same to allow a free passage for its exit from
one compartment to the other; and it will be seen that by this means any dirt, sand,
or sediment which might have accumulated at the entrance of the hole will be
washed or forced back on the return of the quicksilver or other matters, whereas in
the case where the quicksilver or other matters has to return by other openings such
is not the case, and in practise it is found that the hole or aperture through which
it ought to pass becomes plugged up and so the desired action of the valve is prevented.
We form a groove or channel for the ball e, before described, to work or move in,
and provide a stop or guard piece H to prevent it moving or travelling too far away
from the hole or aperture in the connecting piece, and for the plug f a small socket.
or box J is provided to carry one end of it, as shewn in Fig. 2. We construct the
box or frame C in which the said valve hangs in equilibrium in an elongated form,
so that it is continued forward past the brickwork of the bridge B or place in which
it is fixed, and we have an enlarged circular (by preference) or other form of top
with elongated or other form of perforations K made therein, which equally dis-
tribute the current of air admitted by the valve and contained therein amongst the
smoke or other products of combustion. By this construction of box or frame no
ashes, "hardirons," or refuse can get (as by the beretofore employed frame or box)
into the portion where the valve works, and so the valve can always move freely
within, and the box also acts as a greater conductor and distributor of the air in the
required place, and we make provision by a space L formed on the top side for any
ashes or refuse falling on the frame or box to pass out at the end into the bottom of
the flue apart or away from the box, and to prevent the admission of air through
the space we hinge thereto a door M, which may be made of sleet iron or other light
metal. In case a short box or frame M' is used to place the valve in, we construct
the bridge in the form as shewn at Fig. 7 (Sheet 2), which also effectually keeps the
ashes and other refuse from choking up the valve and allows the admission of the
air to the flues as in the case of the employment of the elongated box C the air

page_text: going in the direction indicated by the arrows. At Fig. 3 we have shewn general
arrangement of valve A and elongated box C, with connecting rods as applied in
position in a steam boiler furnace. Fig. 4 illustrates end view, enlarged, of box and
valve, and Fig. 5 is a longitudinal section of same. Figs. 8 and 9 (Sheet 2) are de-
tails of valve A and box M' as when applied to the form of bridge or similar to that
shewn in Fig. 7.
Having thus fully described the nature of our said Invention, and shewn by Draw-
ings how the same may be put into practice, we would have it understood that what
we claim as our Invention and believe to be new is-
Firstly. The improved construction of valve A with the application of the move-
able ball e or plug f, in manner and for purposes substantially as shewn and
described.
Secondly. The application and use of the elongated box C or its equivalent for
keeping the ashes from choking or filling up the space in which the valve A works,
in manner substantially as herein described and illustrated.
In witness whereof, I, the said Joseph Waddington, for and on behalf of myself and
the said Walker Garside, have hereunto set my hand and seal, this First day of Sep-
tember, One thousand eight hundred and seventy-six.
