PROVISIONAL SPECIFICATION left by the said John Wright Carr at the
Office of the Commissioners of Patents, with his Petition, on the 19th
'December 1865.
I, JOHN WRIGHT CARB, residing at Newland Hall, in the Parish of Roxwell,
in the County of Essex, do hereby declare the nature of the said Invention for
"PRODUCING AND APPLYING ROTATING MOTION BY MEANS OF AN APPARATUS TO BE
WORKED BY FLUIDS, STEAM, COMPRESSED AIR, OR BY WATER OR BY GAS," to be
as follows:-
A drum, cylinder, or case fitted upon a shaft or forming part of a shaft
revolves within a larger drum, cylinder, or case, and from the internal drum
a fixed projection extends as far as the inner surface of the external drum.
From the external drum two or more valves or slides pass close up to the
external surface of the internal drum; these valves or slides are movable, and

page_text: are pressed forward or withdrawn either by eccentrics or by cambs and levers.
Steam, water, air, oil, or gas is allowed to enter by means of pipes or openings
to press upon any or upon all parts of the valves or slides. From the internal
drum steam, water, oil, air, or gas is admitted, either by passing through a
part or the whole of the shaft, or through part of the internal drum, or through
both shaft and internal drum, so as to occupy the space between the external
drum and the internal drum, and to press upon the projection of the internal
drom, which pressure causes the internal drum to revolve within the external
drum and to communicate motion to the shaft. The egress of the steam,
water, air, oil, or gas is provided for by permitting it, to pass through a part
or the whole of the shaft, or through both the shaft and the internal drum.
The apparatus is applicable for all purposes of imparting motion.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Wright Carr in the Great Seal Patent Office on the
8th June 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WRIGHT CARR, residing at Newland Hall, in the Parish of Roxwell, in the
County of Essex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of December, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Wright Carr, Her special licence that I, the said John Wright
Carr, my executors, administrators, and assigns, or such others as I, the said
John Wright Carr, my executors, administrators, and assigns, should at any
țime 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 "PRODUCING AND
APPLYING ROTATING MOTION BY MEANS OF AN APPARATUS TO BE WORKED BY
FLUIDS, STEAM, COMPRESSED AIR, OR BY WATER, OR BY GAS," upon the condition
(amongst others) that I, the said John Wright Carr, 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

page_text: 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 John Wright Carr, do hereby declare the
nature of my 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, reference being had to the Sheet of Drawings attached hereto, repre-
senting various views of a motive power engine of the form and construction.
I prefer, that is to say :-
A drum, cylinder, or case fitted upon a shaft or forming part of a shaft:
revolves within a larger drum, cylinder, or case, and from the internal drum
a fixed projection extends as far as the inner surface of the external drum.
From the external drum two or more valves or slides pass close up to the:
external surface of the internal drum; these valves or slides are movable, and:
are pressed forward or withdrawn either by eccentrics or by cambs and levers.:
Steam, water, air, oil, or gas is allowed to enter by means of pipes or open-
ings to press- upon any or upon all parts of the valves or slides. From the.
internal drum steam, water, oil, air, or gas is admitted, either by passing.
through a part or the whole of the shaft, or through part of the internal drum,
or through both shaft and internal drum, so as to occupy the space between
the external drum and the internal drum, and to press upon the projection of
the internal drum, which pressure causes the internal. drum to revolve within
the external drum and to communicate motion to the shaft. The egress of the:
steam, water, air, oil, or gas is provided for by permitting it to pass through a
part or the whole of the shaft, or through both the shaft and internal drum.
The apparatus is applicable for all purposes of imparting motion.
I now proceed to describe the Invention by means of the Drawings num-.
bered 1, 2, 3, 4, 5, 6, 7, and I use the same letters to denote the same parts.
in all the views.
A is the outer drum, cylinder, or case, hereafter to be called the outer
drum; B is the inner drum, cylinder, or case, hereafter to be called the inner,
drum; C is the main shaft ;- D is the open passage in the center of the. said,
shaft; E, E, are valves or slides attached to the respective rods F, F, working,
through stuffing boxes G, G; 'H, H, are stuffing boxes on the main shaft;
J, J, are ports through which the steam or other fluid that is employed to
work the apparatus passes into or makes exit from the main shaft; K is a.
fixed projection upon the inner drum B extending to the inside surface of the
outer drum A, within which it revolves with the inner. drum B.as nèar steam,
or fluid tight as possible; the inner drum B is either attached to or. foruis
:

page_text: part of the main shaft C; L is a camb to raise or depress the levers M, M,
and attached to which are the levers N, N, and these are respectively con-
nected with the rods F, F; P, P, are pipes or ports opening into the pipes or
passages Q, Q; R, R, are standards affixed to the base S for supporting the
main shaft C; T is the fly wheel; U is the driving drum; X is an external
cover for the purpose of containing fluid or substances to diminish loss of heat
occasioned by radiation or contact.
The Drawing represents but one projection, K, but two or more projections
may be affixed to the inner drum. The Drawing represents but two slides or
valves, E, E, but a greater number of slides or valves may be made use of with
corresponding levers. The entire apparatus may be placed in a horizontal, in
a perpendicular, or in any other position; and two or more cylinders or drums,
as already described, may be arranged, upon the same shaft or otherwise. The,
slides or valves, as shown in the Drawing, are arranged to be withdrawn or.
depressed with a motion at right angles with the shaft, but they may be so
constructed as to have motion imparted to them parallel with the shaft, or
they may be so arranged as to have a revolving motion or a screw motion
imparted to them, or they may be so arranged as to be moved backward and
forward in part or in parts of a revolution; the said slides or valves may be
moved by an eccentric instead of by a camb and levers, or partly by an
eccentric and partly by a camb, and partly or wholly by eccentrics, cambs, and
levers. The slides or valves may also be moved by springs, or by fluids, or by.
vapour, or by other means. The Drawing represents two pipes or passages,
in the inner drum, but any number of pipes or passages may be introduced, as
circumstances. may require. I allow steam, water, air, or gas to enter the
chambers of the slides or valves so as to press on the said slides or valves for
the purpose of equalizing pressure and for other purposes. The Invention is:
applicable to condensing and non-condensing engines; it may be used for
pumping air, water, or any liquid or fluid. The vapour or fluid employed and
used to work the said apparatus. may have ingress and egress through a part
or through the whole of the shaft, or partly or wholly through the inner
drum.
Having described the nature of my Invention, so far as the apparatus for
imparting motion is concerned, I proceed to show the manner in which it is to
be performed.
Steam, water, air, gas, or other fluid is, by a pipe or pipes, or by a channel
or channels, conducted into the passage D of the shaft C, passes along the
pipe or passage Q into the recess V between the projection K and the slide or

page_text: valve E, and causes K, and the drum B, and the shaft C attached thereto, to:
revolve, whilst the opposite pipe or passage Q remains open in order to carry.
off any vapour or fluid being in the opposite spaces that are shown by W, W.
Each of the slides or valves are withdrawn or moved by the levers M and N
moved by the camb L, or by other means, at each revolution, so as to allow
the projection K to pass them, after which the said slides or valves are again
replaced. By admitting the fluid employed to work the apparatus in the.
reverse direction, and by allowing the escape also in the reverse direction to
that which has been already described, a reverse motion is imparted to the
inner drum; thus it is the apparatus is adapted to be worked in different-
directions. When the apparatus is to be used as a pump motion may be
imparted by means of machinery to the shaft, the inner drum, and projection,
and the fluid to be pumped is thereby drawn in through the pipes or passages
on the one side of the projection K, and is expelled through the pipes or
passages on the contrary side of the projection K. Thus it is the apparatus
may be used as a force or as a lifting pump, or as an air pump, to allow the
ingress and the egress; and to "cut off" the admission and supply of vapour or
fluid employed to work the apparatus I use a valve that is suitably constructed
for that purpose; I employ also suitable packing, where necessary, to render
the various parts steam or fluid tight. A cog wheel or other means may be
used instead of the drum U which is shown in the Drawing, in order to "take
off" or impart motion by means of the above-described apparatus. Although a
fly wheel is shown in the Drawing, it may in some instances be dispensed
with, as also the external cover X and the standards R, R.
I claim the general arrangement of the various parts in the manner or upon
the principles herein-before described.
Also, the admission into and from the inner drum of the steam, water, air,
or gas, or of the fluid employed to work the apparatus, or or to be raised
or forced by the said apparatus.
Also, the egress into or out of the inner drum of the steam; water, air, or
gas, or the fluid employed to work the said apparatus.
Also, I claim the construction and movement of the slides or valves in the
recesses of the outer drum, and the contrivances for allowing the steam,
water, air, or gas, or of the fluid employed to work the said apparatus, to
press upon the sides, on the back, as well as the front of the said slides or
valves.
I explain that the apparatus, the outer and inner drum, are constructed of
iron or of brass, but they may be constructed of any other metal or hard

page_text: material suitable to withstand pressure or heat. The external cover may be
either of metal, or wood, or of any other material.
In witness whereof, I, the said John Wright Carr, have hereunto set my
hand and seal, this Seventh day of June, One thousand eight hundred
and sixty-six.
Witness,
WILLIAM RAM.
