Year: 1861

page_text: LETTERS PATENT to Adam Woodward, Robert Woodward, and William.
Woodward, all of the City of Manchester, in the County of Lancaster,
Engineers, for the Invention of "IMPROVED ARRANGEMENTS OF COMPOUND
STEAM ENGINES.".
Sealed the 27th May 1862, and dated the 6th December 1861.
PROVISIONAL SPECIFICATION left by the said Adam Woodward, Robert
Woodward, and William Woodward at the Office of the Commissioners
of Patents, with their Petition, on the 6th December 1861.
We, ADAM WOODWARD, ROBERT WOODWARD, and WILLIAM WOODWARD, all
of the City of Manchester, in the County of Lancaster, Engineers, do hereby
declare the nature of the said Invention for "IMPROVED ARRANGEMENTS OF
COMPOUND STEAM ENGINES," to be as follows:-
This Invention consists in employing an oscillating or other cylinder between
the pillars of a beam engine, or between the wall and the pillar. The, cylinder.
is worked by high-pressure steam, and the shaft which it puts in motion is

page_text: coupled to the shaft of the beam engine by spur or bevil gearing of any desired
diameter or proportion. The "steam, after passing through the aforesaid
oscillating or other cylinder, is made to pass into the cylinder of the beam
engine, and thereby forms a compact and efficient compound engine, requiring
no additional foundation or extra engine-house; or the steam may pass into
the condenser of the beam engine, and form another arrangement of compound
engine by coupling the two separate engines together.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Adam Woodward, Robert Woodward, and William Wood-
ward in the Great Seal Patent Office on the 6th June 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ADAM
WOODWARD, ROBERT WOODWARD, and WILLIAM WOODWARD, all of the City of
Manchester, in the County of Lancaster, Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of December, in the year of our
Lord One thousand eight hundred and sixty-one, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Adam Woodward, Robert-Woodward, and William Woodward,
Her special licence that we, the said Adam Woodward, Robert Woodward, and
William Woodward, our executors, administrators and assigns, or such others
as we, the said Adam Woodward, Robert Woodward, and William Wood-
ward, our 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 "IMPROVED ARRANGEMENTS
OF COMPOUND STEAM ENGINES," upon the condition (amongst others) that we,
the said Adam Woodward, Robert Woodward, and William-Woodward, our
executors or administrators, by an instrument in writing under our, or their, or
one of our or their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to be per-
formed, 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.

page_text: NOW KNOW YE, that we, the said Adam Woodward, Robert Wood-
ward, and William Woodward, do hereby declare the nature of our said
Invention, and in what manner the same is to be. performed, to be par-
ticularly described, and ascertained in and by the following statement (that is
to say)
Our Invention consists, firstly, in the arrangement and combination of a
vibratory or fixed cylinder placed between the pillars of a beam engine, or
between the pillars and the wall of the engine-house, thereby requiring no
additional foundation or engine-house. The said vibrating or fixed cylinder is
employed as an auxiliary or pusher to the beam engine, or it may act as a
separate engine. In some cases we take away the pillars of the beam. engine,
and substitute in their place a framework of iron, so constructed as to support
the vibrating or fixed cylinder; or we take away only one of the pillars, or
substitute in its place a framework of iron so constructed as to support one
side of the said vibrating or fixed cylinder, and cause the other side to be
supported by a fixing firmly secured to the wall of the engine-house. We
connect the said vibrating or fixed cylinder to the beam engine by means of a
separate crank, crank shaft, and spur wheels, one end of the crank shaft being
carried by the framework, and the other end working in a bearing fixed in the
wall; through which it is carried, if required, so as to drive a separate part of
the mill. The wheels are made of any desired size or proportion, and the
vibrating or fixed cylinder is worked by high-pressure steam direct from the
boiler, and the steam. after passing through the said cylinder passes to the
cylinder of the beam engine, thereby forming a compact and efficient com-
pound engine; or the vibrating or fixed cylinder may be connected direct with
the condenser of the beam engine, and thus form another arrangement of
compound-engine.
:
Our Invention consists; secondly, in the arrangement and application of a
vibrating or fixed cylinder to a horizontal engine, to act as an auxiliary or
pusher to the said engine: We fix or place at the end of the engine a framing
of cast iron, similar to the one we apply to beam engines, constructed so as to
carry the vibrating or fixed cylinder, as the case may be; the said cylinder is
connected to the horizontal engine by means of a separate crank, crank shaft,
and spur wheels, one end of the crank shaft being carried the said frame-
work, and the other end working in a bearing secured to the wall, through
which it passes if required so as to drive a separate part of the mill, or for any
other' purpose:
Our Invention consists, thirdly, in the improved arrangement and construc-

page_text: tion of the framework for carrying the vibrating or fixed cylinder, so that the
power will be contained within the said framework.
These improvements will be clearly understood by referring to the 'figures
and letters on,
the accompanying Sheet of Drawings, in which Fig. I is a
longitudinal elevation with part in section; Fig. 4; a plan; and Fig. 5, an
end elevation of our improved arrangement and combination of an oscillating
cylinder with a beam engine.

which is connected by the spur wheels E, E, with the shaft of the beam
engine; F, F, are the frames for carrying the oscillating cylinder constructed
so as to be self-contained; G, G, are the trunnions of the oscillating cylinder A

cylinder I; and J, the steam pipe direct from the boiler to the high-pressure
cylinder A:

spur wheels E, E, with the shaft of the beam engine; F represents one of two
frames for carrying the fixed cylinder; they are so constructed as to be self-
contained; H is the exhaust pipe from the fixed cylinder to the cylinder I ;

engine, or the, cylinder may be fixed as in Fig. 2."

B, the piston rod, which is connected to the crank pin C attached to the crank
shaft D, which is connected by the spur wheels E, E, with the horizontal
engine; F, F, are the frames for carrying the oscillating cylinder; they are
so constructed-as-to be self-contained; G, G, are the trunions of the oscillating
cylinder A; H is the exhaust pipe from the oscillating or fixed high-pressure
cylinder to the cylinder I; and J, the steam pipe direct from the boiler to the
high-pressure cylinder A.
Having now described the nature and particulars of our said Invention; and
the manner in which the same is to be performed, we desire it to be under-
stood that we claim as our Invention, and which to the best of our knowledge
and belief has not been hitherto used within the realm, the improved arrange-

page_text: ments of compound steam engines, as herein described and illustrated in the
accompanying Sheet of Drawings.
In witness whereof, I, the said William Woodward, for and on behalf
of myself and the said Adam Woodward and Robert Woodward, have
hereunto set my hand and seal, this Fifth day of June, in the year
of our Lord One thousand eight hundred and sixty-two.
WILLIAM WOODWARD. (L.S.)
