Year: 1868

page_text: LETTERS PATENT to William Samuel Page and Richard East, both of
Nine Elms Wharf, Nine Elms, in the County of Surrey, for the
Invention of "IMPROVED MECHANICAL ARRANGEMENTS APPLICABLE TO STEAM
BOILERS AND THE CYLINDERS OF STEAM AND OTHER MOTIVE-POWER ENGINES
FOR PREVENTING THE PRIMING THEREOF, AND FOR LUBRICATING THE PISTONS
AND CYLINDERS OF ENGINES."
Sealed the 25th September 1868, and dated the 26th March 1868.
PROVISIONAL SPECIFICATION left by the said William Samuel Page
and Richard East at the Office of the Commissioners of Patents,
with their Petition, on the 26th March 1868.
We, WILLIAM SAMUEL PAGE and RICHARD EAST, both of Nine
Elms Wharf, Nine Elms, in the County of Surrey, do hereby declare
the nature of the said Invention for "IMPROVED MECHANICAL ARRANGEMENTS
APPLICABLE TO STEAM BOILERS AND THE CYLINDERS OF STEAM AND OTHER MOTIVE-
POWER ENGINES FOR PREVENTING THE PRIMING THEREOF, AND FOR LUBRICATING
THE PISTONS AND CYLINDERS OF ENGINES," to be as follows:-

page_text: This Invention consists, first, of certain improved mechanical arrange-
ments applied within the steam chest of a boiler employed to generate
steam, and is designed to prevent priming of the cylinders, which we
propose to effect by causing the steam more or less mixed with water to
circulate in a vessel formed with chambers communicating with each
other by perforations made alternately at and around the top and bottom
of the said chambers, by which the steam is separated from the water
before it enters the steam pipe leading to the cylinder of a steam
engine.
Secondly. Of an improved grease cup so constructed as to prevent the
lubricating matter employed from being blown out of it, as is now
commonly the case.
The following is an example of the means by which we propose to
effect the above objects :-
First. As regards steam boilers the mechanism to be applied thereto
consists of a cylindrical-shaped vessel of copper (by preference) formed
with three separate concentric chambers or cylinders placed one within
the other and closed at the top by a plate, space being left between the
cylinders for the passage of steam from the boiler, for which purpose the
bottom of the outermost cylinder is left open; the innermost cylinder is
formed closed at the bottom and with holes or perforations therein; the
intermediate cylinder is formed with a conical-shaped bottom, to which
is connected a pipe for the discharge of water and extraneous matters;
and there are holes or perforations formed around this cylinder near the
top thereof, and the centre cylinder is perforated near the bottom
thereof. The steam pipe leading to the cylinder of the engine is fixed
steam-tight in the central cylinder and dips therein about two-thirds of
the length of this said cylinder; the bottom end of this pipe is closed,
and there are perforations made around the enclosed part of the pipe
for the passage of steam. This mechanism is fixed inside the steam
chest of the boiler, and the steam therefrom enters the outer cylinder
and passing upwards enters the second cylinder by the perforations
therein, thence the steam passes downwards and enters the centre
cylinder by its perforations and finally enters the steam pipe by its
perforations, and in this manner and by these means any water that
may have been mixed with the steam is separated therefrom and is
allowed to pass or. blow off into the open air or water if applied to

page_text: a marine boiler, and thus priming of the cylinders of engines is
prevented.
And as regards the second part of this Invention the construction of
the mechanism is as follows:-
First. A cup or vessel to contain the lubricating matter; this cup is
closed at the top and fitted with two screw valves and a cock for the
admission of atmospheric air into the cup, the bottom of the said cup
screws into the cylinder lid in the usual way, and there is a valve seat
formed in the bottom of the cup, into which a screw valve fits for
opening and closing the communication between the cup and the
inside of the cylinder, and for regulating the quantity of lubricating
matter thereto. The lubricating matter is poured or placed in a small
vessel also fitted with a screw valve and screwed into the top of the
grease cup.
In using a grease cup of the above improved construction and in
order to charge it with lubricating matter the screw valve of the cup is
first closed, the air cock opened, as also the valve of the aforesaid small
vessel by which the lubricating matter is passed until the grease cup is
full; the valve is then closed, also the air-cock, and the valve of the
grease cup opened. By this improved arrangement the grease cannot
be blown out of the greece cup, thereby preventing or lessening waste
thereof.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Samuel Page and Richard East in the
Great Scal Patent Office on the 26th September 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we,
WILLIAM
SAMUEL PAGE and RICHARD EAST, both of Nine Elms Wharf, Nine
Elms, in the County of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her

of our Lord Oue thousand cight hundred and sixty-eight, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said William Samuel Page and Richard East,
Her special licence that we, the said William Samuel Page and Richard

page_text: East, our executors, administrators, and assigns, or such others as we,
the said William Samuel Page and Richard East, 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
MECHANICAL ARRANGEMENTS APPLICABLE TO STEAM BOILERS AND CYLINDERS
OF STEAM AND OTHER MOTIVE-POWER ENGINES FOR PREVENTING THE PRIMING
THEREOF, AND FOR LUBRICATING THE PISTONS AND CYLINDERS OF ENGINES," upon
the condition (amongst others) that we, the said William Samuel
Page and Richard East, our executors or administrators, by an
instrument in writing under our, 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 we, the said William Samuel Page and
Richard East, 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, that is to
say:-
This Invention consists, first, of certain improved mechanical arrange-
ments applied within the steam chest of a boiler employed to generate
steam, and is designed to prevent priming of the cylinders of steam
engines, which we propose to effect, by causing the steam more or
less mixed with water to circulate in a vessel formed with chambers
communicating with each other by perforations made alternately at
and around the top and bottom of the said chambers, by which the
steam is separated from the water before it enters the steam pipe
leading to the cylinder of a steam engine.
Secondly. Of an improved grease cup so constructed as to prevent
the lubricating matter employed from being blown out of it as is
now commonly the case.
The following is an example of the means by which we propose
to effect the above objects:-First, as regards steam boilers, the

page_text: mechanism to be applied thereto consists of a cylindrical shaped
vessel of copper (by preference) formed with four separate concentric
chambers or cylinders placed one within the other and closed at the
top by a plate, space being left between the cylinders for the passage
of steam from the boiler, for which purpose the bottom of the
outermost cylinder is left open; the innermost cylinder is formed with
holes or perforations therein at the top and bottom; the intermediate
cylinders are formed with hemispherical shaped bottoms, to the
outer one of which is connected a pipe for the discharge of water
and extraneous matters, and there are holes or perforations formed
around the cylinder near the top thereof, and the adjoining cylinder
is perforated near the bottom thereof. The steam pipe leading to the
cylinder of the engine is fixed steam-tight to the central cylinder.
This mechanism is fixed inside the steam chest of the boiler, and
the steam therefrom enters the outer cylinder by the perforations
therein, thence the steam passes downwards and enters the centre
cylinders by their perforations and finally enters the steam pipe, and
in this manner and by these means any water that may have been
mixed with the steam is separated therefrom and is allowed to pass
or blow off into the open air or water if applied to a marine boiler,
and thus priming of the cylinders of engines is prevented.

And as regards the second part of this Invention, the construction
of the mechanism is as follows:-First, a cup or vessel to contain
the lubricating matter; this cup is closed at the top and fitted with
two screw valves and a cock for the admission of atmospheric air
into the cup. The bottom of the said cup screws into the cylinder
lid in the usual way, and there is a valve seat formed in the bottom
of the cup, into which a screw valve fits for opening and closing
the communication between the cup and the inside of the cylinder
and for regulating the quantity of lubricating matter thereto. The
lubricating matter is poured or placed in a small vessel also fitted
with a screw valve and screwed into the top of the grease cup!

In using a grease cup of the above mentioned construction, and in
order to charge it with lubricating matter the screw valve of the
cup is first closed, the air cock opened, as also the valve of the
aforesaid small vessel by which the lubricating matter is passed until
the grease cup is full, the valve is then closed, also the air cock and
the valve of the grease cup opened. By this improved arrangement

page_text: to the illustrative Sheet of Drawings accompanying these Presents
and to the numeral figures and letters of reference marked thereon
as follows:-
DESCRIPTION OF THE DRAWING.
Figure 1 represents a transverse and vertical section of the steam
chest of a boiler, shewing our improvements (also in section) adapted
thereto; Figure 2, a transverse and vertical section of a grease cup
constructed according to our said Invention. The parts represented
at Figure 1 are drawn to a geometrical scale of three inches to one
foot, and the grease cup represented at Figure 2 is drawn to a scale
of half full size.
At Figure 1 A marks the steam chest of a boiler B, cast-iron
cylinder bolted thereto all round as at a, a, the said cylinder being
surmounted by a lid C bolted all round to B by bolts and nuts at b, b.
D, E, G, mark perforated copper cylinders formed hemispherical at
their lower ends and with flanges c, c, at their upper ends for con-
necting them to the lid C by bolts and nuts at d, d; H marks a pipe
leading to the cylinder of an engine for conveying the steam thereto;
I, a waste pipe bolted to the cylinder D, and employed to carry off
the water and other extraneous matters from the cylinders D, E, G, as
they are separated from the steam. The cylinder D is perforated all
round near the top thereof only; the cylinder E is perforated
all round the bottom thereof only; and the cylinder G is perforated
at top and bottom as represented. The arrows denoted by solid
lines shew the direction of the passage of the steam through the per-
forated cylinders D, E, G, as it enters the perforations e formed in
the top of the steam chest, and the arrows denoted by dotted lines
shew the direction of the water and other extraneous matters through
the pipe I.
The operations of the above arrangement are as follows:-The
steam from the steam chest being compelled to take a circuitous
route through the cylinders D, E, G, any water and other extraneous

page_text: matters that may be mixed with the steam is thus arrested and.
separated from the steam before it enters the pipe H; the water
and other extraneous matters thus separated passing off by the pipe I,
and in this manner and by these means priming of the cylinders of
steam engines may be effectually prevented.
We now proceed to describe the construction of the grease cup
represented at Figure 2 as follows:-K marks the cup screwed on to:
a piece L for connecting the cup to the cylinder lid of an engine;
the top M of the cup is formed closed and has the following parts
or pieces fitted thereinto:N marks a small cup screwed into M
and fitted with a screw valve f ground into a corresponding shaped seat
formed at the top of the hole g; O marks a plug screwed into M; P,
another screw valve ground into a seal formed at the top of the
hole h; the stem i of this valve works steam-tight through a stuffing
box Q. R is a wheel lever fixed on the top of the stem i for opening
and closing the valve P by turning round the wheel R from right to
left and vice versa.
The operations of this grease cup are as follows:-In order to charge i
the cup with oil or other liquid lubricating matter the valve P should
be closed; the plug O should then be unscrewed a few turns- of the
screw until the hole k therein is open to the atmosphere, the valve fis
then raised and the lubricating matter poured through N into K until it
is filled, the air in the cup passing out by the hole k; this done, the
plug O is screwed down as also the valve f and the valve P raised
from its seat, thus preventing the lubricating matter from being
blown out of the grease cup as before stated.
We would here remark that we do not intend to limit ourselves to
the precise arrangement of the parts as represented by the Drawing at
Figure 1, hut reserve to ourselves the right to place the above-mentioned
arrangement either wholly inside or outside of the steam chest as
may be found desirable in practise.

Having now fully described and set forth the nature and object
of our said Invention for "Improved Mechanical Arrangements
applicable to Steam Boilers and the Cylinders of Steam; and other
Motive-power Engines for Preventing the Priming thereof, and for
Lubricating the Pistons and Cylinders of Engines," together with
the best means we are acquainted with for carrying the same into
practical effect, we would remark in conclusion that what we claim

page_text: as our Invention intended to be secured to us by the herein-before
in part recited Letters Patent is as follows:-
We claim the application of a system of perforated cylinders to the
steam chest of a boiler for separating the water and other extraneous
matters from the steam before it enteres the steam pipe leading to
the engine, as above described with reference to Figure 1 of the
accompanying Drawing.
Secondly. We claim the mode above described and represented at
Figure 2 of constructing the grease cups of steam and other motive
power engines for the purposes above stated.
In witness whereof, we, the said William Samuel Page and Richard
East, have hereunto set our hands and seals, this Twenty-fifth
day of September, in the year of our Lord One thousand eight
hundred and sixty-eight.
