Year: 1870

page_text: LETTERS PATENT to Charles Aston Winder, of Sheffield, in the County
of York, Engineer, for the Invention of "AN IMPROVED APPARATUS
FOR USE IN DRAWING AND FORCING AIR, WATER, AND OTHER FLUIDS."
Sealed the 2nd September 1870, and dated the 10th March 1870.
PROVISIONAL SPECIFICATION left by the said Charles Aston Winder
at the Office of the Commissioners of Patents, with his Petition,
on the 10th March 1870.
I, CHARLES ASTON WINDER, of Sheffield, in the County of York,
Engineer, do hereby declare the nature of the said Invention for
"AN IMPROVED APPARATUS FOR USE IN DRAWING AND FORCING AIR, WATER, AND
OTHER FLUIDS," to be as follows:-
Within a cylindrical case with closed ends are supported to turn on a
common centre of motion two pistons or wings which I prefer to be
wedge shaped. These pistons though capable of working on a common
centre of motion are yet driven independently and at speeds varying the
one to the other during their common revolution by means of pairs of

page_text: excentric wheels. One of each pair of these excentrically placed wheels
is affixed on the shaft of each piston or wing with the excentricity of one
in the opposite direction to that of the other. The teeth of these two
excentrically placed wheels are taken into by the teeth of other corre-
spondingly placed excentric wheels affixed on the main shaft of the
apparatus to give motion to the pistons. By these means different speeds
which are alternately relatively varying will be communicated in a rotary
direction to these vanes or pistons, and each piston in its rotation becomes
an abutment for the fluid set in motion by the other. The shape or form
of and method of giving motion to the pistons may be varied. By these
means a simple and effective engine to be used as a blowing engine or
for other purposes of drawing and forcing air, water, and other fluids is
obtained.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Aston Winder in the Great Seal Patent
Office on the 10th September 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
ASTON WINDER, of Sheffield, in the County of York, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of March, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Charles Aston Winder, Her special
licence that I, the said Charles Aston Winder, my executors, adminis-
trators, and assigns, or such others as I, the said Charles Aston Winder,
my executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "AN IMPROVED
APPARATUS FOR USE IN DRAWING AND FORCING AIR, WATER, AND OTHER FLUIDS,"
upon the condition (amongst others) that I, the said Charles Aston Winder,
my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, should particularly describe

page_text: and ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Charles Aston Winder, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, that is to say :—
Within a cylindrical case with closed ends are supported to turn on a
common centre of motion two pistons or wings which I prefer to be
wedge shaped. These pistons though capable of working on a common
centre of motion are yet driven independently and at speeds varying the
one to the other during their common revolution by means of pairs of
excentric wheels or otherwise. One of each pair of these excentrically
placed wheels is affixed on the shaft of each piston or wing with the
excentricity of one in the opposite direction to that of the other. The
teeth of these two excentrically placed wheels are taken into by the teeth
of other correspondingly placed excentric wheels affixed on the main
shaft of the apparatus to give motion to the pistons. By these means
different speeds which are alternately relatively varying will be com-
municated in a rotary direction to these vanes or pistons, and each piston
in its rotation becomes an abutment for the fluid set in motion by the
other. The shape or form of and method of giving motion to the pistons
may be varied. By these means a simple and effective engine to be used
as a blowing engine or for other purposes of drawing and forcing air,
water, and other fluids is obtained.
But that the Invention may be fully understood, I will by the aid
of the accompanying Drawings proceed to describe means pursued by
me in carrying the same into effect.
DESCRIPTION OF THE DRAWINGS.
Figure 1 represents a front elevation of an engine constructed according
to my Invention; Figure 2 is a plan view of the same; Figure 3 is a
sectional view; Figures 4, 5, and 6 show parts separately. In each of
the views the same letters indicate corresponding parts wherever they

page_text: gearing wheels; one half of one of these casings is shown separately at
Figure 6. F and G are the two pistons or wings, and F¹, G₁, are the
shafts to which they are respectively affixed. On the shaft F¹ is affixed
the excentric toothed wheel F, and on the shaft G¹ the excentric toothed
wheel G. The excentricity of the wheel G³ is in the opposite direction
to that of the wheel F³, and the teeth of these two wheels Fº, G², respec-
tively take into the teeth of similar excentric tooth wheels E' and E*
affixed on the main shaft or axis E. H is a driving pulley, and I a fly
wheel, each affixed on the shaft E; K and L are the ports from the
passages K¹, L'. By the arrangement shown one piston or wing, say F,
will by moving between the ports K and L during the time that the
other G is moving in the direction of the arrow from L to K, and then
that piston or wing G in its turn forms an abutment between the two
ports for the movement of the other (F), each in its turn forcing with it
the fluid that has to be set in motion. Thus it will be seen that both
pistons or wings though affixed to separate shafts to move independently
both work from the same centre of motion and are each governed by
excentric cog wheels to work at varying speeds, so that while one piston
is travelling between the ports the other acts as an abutment.
Having thus described my Invention and means which I adopt in 1
carrying the same into effect, I would have it understood that what I
claim is, the arranging or combining apparatus for use in drawing and
forcing air, water, and other fluids, substantially as described.
In witness whereof, I, the said Charles Aston Winder, have hereunto
set my hand and seal, this First day of September, in the year of
our Lord One thousand eight hundred and seventy.
