AN IMPROVED CONSTRUCTION OF STEAM MOTOR
Year: 1866

page_text: LETTERS PATENT to Alfred Vincent Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Mechanical Draughts-.
man, for the Invention of "AN IMPROVED CONSTRUCTION OF STEAM MOTOR,"
- A communication from abroad by Samuel Harris, of Rochester, in
the State of Michigan United States of America
Sealed the 21st May 1867, and dated the 14th December 1866.
PROVISIONAL SPECIFICATION left by the said Alfred Vincent Newton
at the Office of the Commissioners of Patents, with his Petition, on the
14th December 1866.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Mechanical Draughtsman, do hereby declare
the nature of the said Invention for "AN IMPROVED CONSTRUCTION OF STEAM
MOTOR," to be as follows:-
The object of this Invention is to produce motive power by the force of
steam acting on a reaction and direct action wheel, both however at the same
time.
In bearings on a rigid frame two shafts are mounted in a line with each
other, the one carries on its inner end a cup-shaped disc, and the other
(which is hollow) carries one or more pairs of hollow arms, which arms are

page_text: bent at their ends in opposite directions and are intended to rotate within the.
cup-shaped dise; these arms are hollow and communicate with their hollow
shaft for the purpose of allowing steam to pass through them.
A casing
fastened to the framing encloses the disc and serves to confine the steam and
ensure its escape through a waste pipe connected with the casing. An open-
ing is provided in the bottom of the casing for the purpose of discharging the
condensed water. The outer end of the shaft carrying the hollow arm is
fitted with a hollow head into which projects a steam supply pipe; this pipe
is fitted with a nut shaped to fit in the hollow head like a valve on its seat; as
therefore the steam is admitted to the engine the nut or valve will be pressed
into its sent, thereby making à steam-tight joint. On the inner periphery of
the cup-shaped disc buckets are formed to receive the impact of the steam.
discharged from the hollow arms. These surfaces for the impact of the steam
admit of being made in many ways; one is to fasten arms on the inner end
of a solid shaft, and to secure to the outer end of these arms a ring of thin
iron bent edgewise; to this a ring of iron bent flatwise and of sufficient width
is fastened. The buckets made of thin metal are placed inside the outer ring,
and another ring of iron bent edgewise is secured to the outer side of the
buckets.
The operation of the engine is as follows:-Steam being admitted to the
hollow axle will pass out at the hollow arms and cause them to revolve by
the force of the action or unbalanced pressure, at the same time the steam
impinging on, the buckets will drive round the disc and its shaft in the
opposite direction by the force of direct action.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alfred Vincent Newton in the Great Seal Patent Office on
the 14th June 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Mechanical Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of December, in the year of our
Lord One thousand eight hundred and sixty-six, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Alfred Vincent Newton, Her special licence that I, the said Alfred
Vincent Newton, my executors, administrators, and assigns, or such others

page_text: as I, the said Alfred Vincent Newton, 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 CONSTRUCTION OF STEAM MOTOR," being a com-
munication to me from abroad, upon the condition (amongst others) that.
I the said Alfred Vincent Newton, 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 I, the said Alfred, Vincent Newton, 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)
The object of this Invention, as communicated to me from abroad, is to
produce motive power by the force of steam acting on a reaction and direct
action wheel, both however at the same time.
- In the accompanying Drawing Fig. 1 represents in front elevation, partly in
section, the improved construction of engine employed for this purpose, and
Fig. 2 is a vertical section on the line 1, 2, of Fig. 1..
A represents the frame; B, a shaft supported on two bearings a, a, carry-
ing on its inner end a cup-shaped disc C; D is a hollow shaft supported on
two bearings.b, b, and placed in a line with the shaft B. The hollow shaft D.
carries a pair or it may be two or more pairs of hollow arms E, E. Tho
object of making the shaft D and its attached arms hollow is to allow steam
to pass through them. I is a casing fastened to the frame A. It is made
of wood or iron, and is for the purpose of confining the steam that is dis-
charged from the open-ends of the arms E and preventing its
into the
escape
engine room. i is a pipe for carrying off the steam after it has exerted its
force upon the working parts of the engine. The casing I has a

coupling screwed on the outer end of the shaft D, and formed with a socket
to receive the end of a steam pipe. G. The inner end of this pipe is formed
with a shoulder which fits into the coupling like a valve in its seat; as there-
fore steam is admitted to the engine its tendency is to press the shoulder
hole in its

page_text: against the socket of the coupling, and thereby make a steam-tight joint.
On the inner periphery of the cup-shaped disc buckets are formed as shown
at D¹ to receive the impact of the steam discharged from the hollow
arms E, E. These surfaces for the impact of the steam and the parts that
carry them admit of being made in many ways; one is to fasten arms on the
inner end of the shaft B, and to secure to the outer end of these arms a ring
of thin iron bent edgewise. To this a ring of iron bent flatwise and of
sufficient width is fastened so as to stand at right angles thereto. The
buckets D' are made of thin metal, and are placed inside the outer ring and
another ring of iron bent edgewise is secured to the outer side of the
buckets D¹; a bucket wheel is thus formed having the sectional shape shewn
at C in Fig. 1. The hollow arms E can be cast of brass with the proper
sized hole or bore; they are bent at their outer end in opposite directions.
If there are four or more arms, two or more can have a stop cock near the
shaft D, so that steam will only act on two or more at pleasure.
The operation of the engine is as follows:-Steam being admitted to the
hollow axle D through the pipe G will pass out at the hollow arms E and
cause them to revolve by the force of reaction or unbalanced pressure, at the
same time the steam impinging on the buckets D¹ will drive round the
bucket wheel C and its shaft B in the opposite direction by the force of direct
action.
Having now set forth the nature of the Invention of "An Improved Con-
struction of Steam Motor," as communicated to me from abroad, and
explained the manner of carrying the same into effect, I wish it to be under-
stood that under the above in part recited Letters Patent I claim, the
arrangement of parts above described whereby I am enabled to secure and
utilize the power of reaction and direct action of the same steam.
In witness whereof, I, the said Alfred Vincent Newton, have hereunto
set my hand and seal, the Fourteenth day of June, in the year of our
Lord One thousand eight hundred and sixty-seven.
