Year: 1866

page_text: LETTERS PATENT to John Beale, of East Greenwich, in the County of
Kent, Engineer, for the Invention of "AN IMPROVED ROTARY ENGINE TO
DE TEEN BAD PRIMPING FLUIDS OR GASES. OR AS MOTIVE POWER."
PROVISIONAL SPECIFICATION left by the said John Beale at the
Office of the Commissioners of Patents, with his Petition, on the
17th May 1866.
I, JOHN BEALE, of East Greenwich, in the County of Kent, Engineer, do
hereby declare the nature of the said Invention for "AN IMPROVED ROTARY
ENGINE TO BE USED FOR PUMPING FLUIDS, OR GASES, OR AS A MOTIVE POWER," to be
as follows:-
My Invention consists in the combination of sliding pistons and revolving
rings of the construction and in the manner herein-after described.
The engine is composed of an outer casing or cylinder furnished with an
inlet and outlet as usual. Within this outer casing is fitted a revolving drum,
the axle of which passes through a stuffing box at each end or at one end
only, and is carried on antifriction rollers or otherwise. This revolving drum
is mounted so as to be excentric in relation to the stationary outer casing or
cylinder, and is slotted to allow two pistons or partitions (connected so as to

page_text: act as one) to slide in the drum in such a manner that the outer ends of the
pistons or partitions may be always kept in contact with the interior of the
stationary casing or cylinder. One of, the pistons or partitions is larger than
the other, the smaller piston being inserted in a slot formed at one end of the
larger piston. By this connection of the two pistons respectively, the smaller
becomes an elongation of the larger, and they together constitute one piston
or partition extending across the whole interior of the stationary case or
cylinder. The larger piston is connected at one end by means of pins with
rings capable of revolving in annular grooves formed in the end plates of the
stationary case or cylinder, and the smaller piston (at the reverse end of the
larger) is similarly connected with guide blocks, which work within curvilinear
grooves or slots in the said rings.
By the foregoing arrangement of the parts on the revolution of the axle the
drum carries round the sliding pistons, the end or edge of the larger piston
being kept in contact with the interior of the stationary case or cylinder by
the pins fitting into eyes in the concentric rings, and the end or edge of the
smaller piston being kept in contact with the said interior by the sliding guide
blocks working in the curvilinear grooves or slots formed in the rings.
The engine may be worked either as a pump or exhauster as above described
by applying power to the axle, or as a motive power by the pressure of steam
or other fluid on the pistons, such steam or other fluid being admitted and
allowed to escape in the usual way; the parts may be packed and the ordinary
reversing slide fitted as usual.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Beale in the Great Seal Patent Office on the 16th
November 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
BEALE, of East Greenwich, in the County of Kent, Engineer, send greeting...
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of May, in the year of our Lord One
thousand eight hundred and sixty-six, in the twenty-ninth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
John Beale, Her special licence that I, the said John Beale, my executors,
administrators, and assigns, or such others as I, the said John Beale, 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

page_text: 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 ROTARY ENGINE TO BE USED
FOR PUMPING FLUIDS, OR GASES, OR AS A MOTIVE POWER," upon the condition
(amongst others) that I, the said John Beale, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe 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 L, the said John Beale, 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, reference being had to the Drawing hereunto annexed, and to the
letters and figures marked thereon (that is to say) =
My Invention of "An Improved Rotary Engine to be used for Pumping
Fluids or Gases, or as a Motive Power," consists in the combination of sliding
pistons and revolving rings, of the construction and in the manner herein-after
described.
The engine is composed of an outer casing or cylinder, furnished with
an inlet and outlet as usual. Within this outer casing is fitted a revolving
drum, the axle of which passes through a stuffing box, at each end or at one
end only, and is carried on antifriction rollers or otherwise. This revolving
drum is mounted so as to be excentric in relation to the outer casing or
cylinder, and is slotted to allow two pistons or partitions (connected so as to
act as one) to slide in the drum in such a manner that the outer ends of the
pistons or partitions may be always kept in contact with the interior of the
stationary casing or cylinder. One of the pistons or partitions is larger than
the other, the smaller piston being inserted in a slot formed at one end of the
larger piston. By this connection of the two pistons respectively the smaller
becomes an elongation of the larger, and they together constitute one piston
or partition extending across the whole interior of the stationary case or
cylinder. The larger piston is connected at one end by means of pins with
rings capable of revolving in annular grooves formed in the end plates of the
stationary case or cylinder, and the smaller piston (at the reverse end of the
larger) is similarly connected with guide blocks, which work within curvilinear
grooves or slots in the said rings.
-
By the foregoing arrangement of the parts, on the revolution of the axle
the drum carries round the sliding pistons, the end or edge of the larger piston

page_text: being kept in contact with the interior of the stationary case or cylinder by
the pins fitting into eyes in the concentric rings, and the end or edge of the
smaller piston being kept in contact with the said interior by the sliding guide
blocks working in the curvilinear grooves or slots formed in the rings. The
engine may be worked either as a pump or exhauster as above described,
by applying motive power to the axle, or as a prime mover by the pressure of
steam or other fluid on the pistons, such steam or other fluid being admitted
and allowed to escape in the usual way. The parts may be packed and the
ordinary reversing slide fitted as usual.
Having thus stated the nature of the said Invention I will proceed to 1
describe more particularly in what manner the same is to be performed, by
reference to the accompanying Drawings, in which is represented a rotary
engine adapted more especially for use as a gas exhauster.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is an elevation of the engine, with the end plate removed in order to 1
shew the internal construction; Fig. 2 is a horizontal section through the
sliding pistons; and Fig. 3 represents the end plate turned face upwards
and shewing the revolving ring with the curvilinear groove and guide block.
In these several Figures the same letters of reference indicate corresponding
parts.
A is the outer case or cylinder, with an inlet and outlet B, B, as usual; C is
the revolving drum, the axle D of which passes through a stuffing box at each
end or at one end only, as shewn at E in Fig. 2. This axle is carried on anti-
friction rollers or otherwise. The revolving drum C is excentric in relation
to the outer casing or cylinder A, as shewn in Fig. 1; F and G are a larger g
and smaller piston or partition (which are connected together and act as one
piston or partition), the extreme ends of which are kept in contact with the
interior of the stationary case or cylinder A, as the drum C revolves therein.
The larger piston or partition F passes through a slot formed in the drum C,
and is slotted at one end as shewn in Fig. 1, in order to receive the smaller
piston or partition G and allow of its working therein as required, so as to
accommodate the length of the entire piston or partition to the varying length
required by the excentricity of the revolving drum C, and keep the said piston
or partition always in contact with the interior of the stationary casing or
cylinder A. The larger piston or partition F is furnished at one end or edge
with two pins H, H, which are inserted in two corresponding eyes formed in
revolving rings I, 1; and the smaller piston or partition G is also furnished
with two pins K, K, fitted with guide blocks L, working in curvilinear

page_text: grooves M formed in the rings I, I. These rings revolve in annular grooves con-
centric to the bore of the case or cylinder A formed in the end plates thereof.
The working of the engine when used as a gas exhauster or a pump is as
follows: On the revolution of the axle D the drum C carries round the
sliding pistons or partitions F and G, the end or edge of the larger piston or
partition F being kept in contact with the interior of the stationary case or
cylinder A, by the pins H, H, fitting into the eyes in the concentric rings I, I,
and the end or edge of the smaller piston or partition G being kept in contact
with the same by the guide blocks connected to the pins K, K, working in
the curvilinear grooves M formed in the rings I, I. Motion may be given to
the engine, in either direction, by the pressure of steam or other fluid or gas
cau-ed to act on the pistons or partitions F and G, when used as a motive
power, or by a band, rigger, or otherwise when used as a pump. Also the
parts may be packed in the usual way as herein-before stated.
Having thus described the nature of the said Invention, and in what
manner the same is to be performed, I hereby declare that I do not claim as
of my Invention any of the parts represented and described, except as herein-
after stated. But what I do claim as of my Invention is, the combination of
sliding pistons and revolving rings, constructed and working in the manner
herein-before described.
In witness whereof, I, the said John Beale, have herounto set my hand
and seal, the Fourteenth day of November, in the year of our Lord
One thousand eight hundred and sixty-six.
