I WILLIAM JENNINGS, Decorator of 182 Great Titchfield Street in the Parish
of Marylebone Middlesex do hereby declare the nature of my Invention for
APPARATUS FOR VENTILATING COAL MINES RAILWAY TUNNELS, HOSPITALS,
MANSIONS AND OTHER LARGE BUILDINGS to be as follows:-
An apparatus so constructed that by means of a Fan and Sliding Valves, all
gases, foul airs etc will be drawn to the surface in the case of Coal Mines or
Railway tunnels; or withdrawn from each floor in the case of buildings, at the
same time a constant and regular supply of Fresh Air will be infused.
Dated this Rinat day of January 1884

page_text: I WILLIAM JENNINGS, Builder & Decorator of No 182 Great Titchfield Street,
Marylebone London in the County of Middlesex do hereby declare the nature of
my Invention for VENTILATING COAL AND OTHER MINES, RAILWAY TUNNELS,
SEWER'S, HOSPITALS, MANSION'S, THEATRE'S AND OTHER LARGE BUILDINGS" and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :—
These
My Invention is a construction of a ventilating apparatus by Fans, and Pistons
which all work in conjunction. The Fans A and Bs are constructed, as shewn in
drawings with eight blades each but a more or less number of blades can be used
if necessary, the front or outer edges to blades of Fans A and Bs are curved
outwards which, thus forms a double edge (as shewn on drawings) to have the one
and the same effect when the Fans, A and Bs are reversed. This plan of curving
the double edges gives a greater power of exhaust then any other.
Fans A and Bs all work inside a conical shaped airtight chamber H or (any other
shaped chamber to suite circumstances). The outer edges of blades to the large
vertical Fan A are fitted with three tie rings W. which also act as bosses to cog
driving wheels K and also to tie all the blades to Fan A together, and make them
firm. This Fan A is shaped to a workable distance from the sides of air tight
chamber H. and has vertical bearings which causes an Horizontal motion.
To the inner edges of blades of Fan A, a vertical square frame C. is fixed, and
also to the casing to Centre Pinion P and in this vertical frame C, a number of
Fans Bs work in it on Horizontal bearings which causes a circular, vertical and
Horizontal motion. At one time, the motion of the Fans B's are given by cog
driving wheels K, running on top-side and underside of cog rails E fixed round the
inside of conical chamber H. The driving wheels K on the floor-line is the largest
in diameter. The driving wheels K 2, in the middle of chamber H are a little
less in diameter and the top driving wheels K, 3, are a little less in diameter
then driving wheels K. 2. This gives the Fans Bs a quicker motion from the
bottom to the top, all these Fans B's have two tie rings each (as shewn in drawings)
and are the same diameter; and by this arrangement the top Fans Bs 3 pull up
from Fans Bs 2 and Bs 2 pulls up from the bottom Fans Bs 1. When all these
Fans A and Bs are in motion together they give the lifting power of the
Whirlwind. On the top of outside casing M a dome J. is fixed and receives the
whole force of the contents caused by the combined actions of Fans A and Bs, to
the dome J, are fixed two Horizontal tubes L, which conduct the contents from
dome J, into two vertical tubes G, where the two Pistons R and S work inside by
a Cord X, fastened to the top V of Piston R, to V at Piston S. The cord X running
over a pulley wheel at the top of vertical tubes Gs and also a Cord X 2 fastened to
the bottom T of each Piston R. and S, and works under a pulley wheel Y, fixed
under the bottom of vertical tubes Gs (as shewn on drawings), these two vertical
tubes Gs are fixed from the bottom of, and to the side and to the top of shaft to
mine, where two spiral-spring valves work, which prevent any return from one
vertical tube to the other. Each spiral spring is lifted up when the Pistons R and S
are ascending and are closed when either Pistons R and S when descending
Round the sides of Pistons R. and S a space is left by two flanges one at the top
of the Pistons and another flange at the bottom of Pistons R. and S. This space
made as a stuffing box so that the Pistons, R and S will slide up and down the
vertical tubes Gs and fit airtight. When the Pistons R and S, reach the top the
filled contents in the vertical tubes G's have passed the spiral-spring valves these

contents are conducted further in pipes to be stored for use or wasted.
decending Piston R opens by slide which is caused by the return movement, and
allows the filled contents in the tubes to pass through the Pistons R and S without
causing a downward pressure.
Both Pistons S and R work up and down alternately and both have cushioned
flanges at bottom T, and both open and shut in their respective positions each
Piston has a whistle fixed inside; as the contents pass through them the whistle
will give warning to the man in charge of the apparatus of its approach. The
relation of these Pistons S. and R. with the Fans A and Bs are that they draw up
the contents from the Fans A and Bs and relieves them from the lifting pressure
and greatly facilitates the Fans A and Bs with greater power in drawing off the
Gasses or foul air out of the workings of a mine into the apparatus and also
forcing it up to the surface harmless.
The prime motion is given by Machinery encased in two sides of apparatus M
and under the floor of airtight chamber H and is worked by either Manuel A. 2,
Animal A. 4, Steam A. 3, or any other power practicable.
The whole of the Machinery is set in motion by wheel A 2 which acts upon A 3,
and A 3 works on the top Cog Ring of double Contrite wheel N and the outside
cog'd edge of this wheel N gives the motion to the centre pinion, to Fans A and Bs
also to wheel A, 5, which is set in motion by the cog'd ring underside of the double
contrite wheel N, the wheel A, 5, acts also as a rest to double contrite wheel N and
also works the Horizontal shafting Z to Pully wheels Y, and Cords X to
Pistons, R and S.
The working of the Machinery from the opposite side of Apparatus is by animal
power A 4 which this part of Machinery connects with the centre pinion P under
floor of air tight chamber H and also a set of Machinery connected to line of roof
up to wheel O, on the top of centre pinion P this part to be used in case of accident
to the other parts.
The plan of the apparatus is octagon but can be made to any shape to suit
circumstances. The eight sides are provided with three suction tubes D each,
more can be put on if wanted and every tube has a stop cock so that the apparatus
can be used with greater effect at any particular point in cases of emergency, the
whole of the stop cocks could be opened at one time if necessary or any number
required. Under the wheel O, is a hollow cup-shaped receiver F for oil to
lubricate the whole of the Fans A and Bs, by conducts and channels (as shewn on
drawings) Section No 2 where the chanuels and conducts are shewn F to to the
Fans A and Bs and behind A, 2, to A, 3, over the top of pinion N to the centre
pinion P and over the top Q to wheel E from the top of E, to the bottom, then to
the bottom of Q and to the centre pinion P, then to the double contrite wheel N
then to wheel A, 5, to horizontal shafting Z, from here into a well where it can be
taken out and refined again for use.
Having now particularly described and ascertained the nature of my said
invention and in what manner it is to be performed I declare that what I
claim is―
1st Constructing an arrangement of Fans all working together in combination
and in an airtight chamber and all the motions of which are given from one central
point substantially as and for the purpose herein set forth.
