Year: 1880

page_text: LETTERS PATENT to Thomas Jones, of Maindy House, near Pontypridd, in the
County of Glamorgan, Colliery Proprietor, for an Invention of "IMPROVEMENTS
IN APPARATUS FOR GENERATING AND APPLYING STEAM FOR VENTILATING
MINES AND OTHER PLACES."
PROVISIONAL SPECIFICATION left by the said Thomas Jones at the Office
of the Commissioners of Patents on the 17th January 1880.
THOMAS JONES, of Maindy House, near Pontypridd, in the County of Glamorgan,
Colliery Proprietor. "IMPROVEMENTS IN APPARATUS FOR GENERATING AND
APPLYING STEAM FOR VENTILATING MINES AND OTHER PLACES."
In carrying out my improvements a boiler with its furnace is applied in or in
connection with the upcast shaft of a mine or other place to be ventilated with a
water heating chamber for the supply of the boiler surrounding the flue from such
furnace. Above this water heating chamber there is a steam heating chamber also
surrounding the flue. These water heating and steam heating chambers extend up
the flue a considerable distance, depending on the extent of heating power in the
products of combustion in the flue.
The steam portion of the boiler and the steam generating chamber are connected
by a pipe or pipes, and such pipe or pipes as well as the steam heating chamber are
provided with jets or outlets for the escape of jets of steam in an upward direction,
so as to create or facilitate an upward current in such upcast shaft.
From this steam heating chamber I also conduct a steam pipe or pipes up the
upcast shaft, which is also provided with suitable outlet passages for jets of steam
to rise in an upward direction.
By these means a succession of jets of steam may be obtained progressively to
aid in raising the foul air or gases and facilitate the discharge thereof.
By these means life and property may be preserved, and the working in mines or
other places will be facilitated.
The supply of water to the boiler may in most cases be obtained of adequate
pressure by the collection thereof from the sides of pits through a suitable pipe or
pipes without the necessity for the use of an injector or other feed means.
Relieving valves, passages, or outlets may be employed at different elevations
in such feed pipe or pipes as may be desired to guard against excess of pressure.
Safety valves and pressure gauges are applied as desired.
Steam from the steam generator may also supply motive power to pumping,
hauling, or other engines, either at the bottom or surface or other part of the mine
or other place.

THOMAS JONES, of Maindy House, near Pontypridd, in the County of Glamorgan,
Colliery Proprietor. "IMPROVEMENTS IN APPARATUS FOR GENERATING AND
APPLYING STEAM FOR VENTILATING MINES AND OTHER PLACES."
In carrying out my improvements a boiler with its furnace is applied in or in
connection with the upcast shaft of a mine or other place to be ventilated with a
water heating chamber for the supply of the boiler surrounding the flue from such
furnace. Above this water heating chamber there is a steam heating chamber also
surrounding the flue. These water heating and steam heating chambers extend up
the flue a considerable distance, depending on the extent of heating power in the
products of combustion in the flue.
The steam portion of the boiler and the steam generating chamber are connected
by a pipe or pipes, and such pipe or pipes as well as the steam heating chamber are
provided with jets or outlets for the escape of jets of steam in an upward direction,
so as to create or facilitate an upward current in such upcast shaft.
From this steam heating chamber I also conduct a steam pipe or pipes up the
upcast shaft, which is also provided with suitable outlet passages for jets of steam
to rise in an upward direction.
By these means a succession of jets of steam may be obtained progressively to
aid in raising the foul air or gases and to facilitate the discharge thereof.
But that the Invention may be more clearly understood I will by the aid of
the accompanying Drawings proceed to describe means I adopt in carrying the
same into effect.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows the vertical section, and Figure 2 a plan of an arrangement of
workings with up and downcast shafts thereto together with a system of generating
and applying steam for ventilating the same according to my Invention; Figure 3
shows to an enlarged scale the system of generating the steam and effecting the
ventilation more clearly. In each of the views the same letters are used to indicate
corresponding parts; a, a, in Figures 1 and 2 indicates the main roadway; b, the
return airway; c, c, cross passages provided with doors c¹, c¹, for regulating the
drafts; d, in Figures 1 and 2, indicates the downcast shaft, and e the upcast shaft.
The apparatus for generating the steam is indicated at g in these Figures, and g¹ is
the flue therefrom. The boiler g (Figure 3) is formed to receive the fire place
within it at h with a passage therefrom h¹, serving as a flue space to conduct the
heated products of combustion from the fire place to the flue g³, and thence up the
shaft e.
Assuming that the water in the boiler would be regulated to rise to the dotted
line, the space h³ above that line 2 would be occupied by steam; i is the water
chamber surrounding part of the flue gl, by which the water contained therein
becomes heated by the heat of the flue g₁ for the supply of heated water to the
boiler g.
Above the chamber i, and still surrounding part of the flue g¹ so as to receive
beat therefrom, is the steam chamber j, which is in communication with the steam
chamber h³ of the boiler g by means of the pipe k, whilst the upper part of the
water heating chamber i, i, and the boiler g are in communication by means of the
pipe l, and the chamber i is supplied from above by a pipe m, which is also
provided with a pressure indicator m³. There is also a pressure indicator n applied
to the steam chamber ³, and another pressure indicator o to the steam chamberj;

page_text: k¹, k³, are jets applied to the steam pipe k for escape of steam therefrom for the
purpose of creating the upward current in the upcast shaft, and there are also other
jets for the same purpose applied to the surface of the steam chamber j; j³ is a
steam pipe from the chamber with jets j¹ thereto, which may be continued up the
shafte to such height as may be desired further to aid the upward current in that
shaft e.
By these means life and property may be preserved, and the working in mines or
other places will be facilitated.
The supply of water to the boiler may in most cases be obtained of adequate
pressure by the collection thereof from the sides of pits through a suitable pipe m
or pipes without the necessity for the use of an injector or other feed means.
Relieving valves, passages, or outlets may be employed at different elevations in
such feed pipe or pipes as may be desired to guard against excess of pressure.
Safety valves and pressure gauges are applied as desired.
Steam from the steam generator may also supply motive power to pumping,
hauling, or other engines, either at the bottom or surface or other part of the mine
or other place by means of a pipe p, or otherwise.
Having thus described my Invention and means I adopt in carrying the same
into effect, I would have it understood that what I claim is, the arranging or
combining parts forming apparatus for generating and applying steam for
ventilating mines and other places, substantially as described.
In witness whereof, I, the said Thomas Jones, have hereunto set my hand
and seal, this Sixteenth day of July, in the year of our Lord One thousand
eight hundred and eighty.
