PROVISIONAL SPECIFICATION left by the said Robert Joseph Ellis
at the Office of the Commissioners of Patents, with his Petition,
on the 7th September 1875.
I, ROBERT JOSEPH ELLIS, of Liverpool, in the County of Lancaster,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN TUBULAR WATER CIRCULATING FIRE-BARS AND CONNECTING BEARERS FOR SAME,”
to be as follows :—
My Invention relates to improvements in that class of fire-bars known
as tubular or water circulating fire-bars, and parts appertaining thereto,
such fire-bars being also used to heat the feed water supplied to steam
boilers, and consists of improvements and modifications on a former

page_text: Invention for which I obtained Letters Patent dated 26th day of
February 1872, No. 611.
My Invention consists of casting the bar proper in the form of a box,
having a suitable channel to receive a loose metal return tube, by
preference of copper or brass. The bar is so formed that the tube can
be laid in the channel and bedded up with "rust" or cement. The
ends of the tube are made to project through holes in the front end
of.the bar, forming projections or nipples thereon. The side of the bar
-is-covered over¯with a wrought or cast-iron plate which is bolted or
rivetted to the bar and holds the metal tube and “rust” or cement
packing in place. The front ends of the bars are faced and made to
butt up against a front bearer which has a ridge or flange cast on its
under side to bear the weight of the bars. The bearer is made with a
double channel or passage way, so arranged that one passage being the
upper passage connects with the upper portion of the tube, and the
other passage or under passage connects with the under portion of
the tube. The connection is made by the nipples formed by the tubes
on the ends of the bars taking into corresponding holes on the side of
the bearer, the bearer being faced to receive the ends of the bars, the
joint being made in any suitable manner. The bars are held up to the
bearer by bolts or studs which pass between the passage ways in the
bearer, and screw into the bars between the respective nipples formed
by the ends of the tubes. The bearer is made, by preference, with its
front open
so that the tubes can be got at for cleaning, the front of the
bearer being covered with a suitable plate or plates which are bolted or
otherwise attached thereto. The bearer is fitted with two branches
provided with suitable flanges, one branch opening into the under
passage and the other branch opening into the upper passage. These
branches are provided with suitable valves and pipes so arranged that
the water from the boiler can be made to circulate through the-bars, or
the feed water can be passed through the bar as-may be required, the
principle of circulation being similar to that described in the Specification
of Letters Patent-before-mentioned-granted-to-me on the 26th day of

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Joseph Ellis in the Great Seal Patent
Office on the 6th March 1876..

NOW KNOW YE, that I, the said Robert Joseph Ellis, 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:
My Invention relates to improvements in that class of fire-bars known
as tubular or water circulating fire-bars and parts appertaining thereto,
such fire-bars being also used to heat the feed water supplied to steam
boilers, and consists of improvements and modifications of a former
Invention for which I obtained Letters Patent dated 26th February -
1872, No. 611.

My Invention consists in casting the bar proper in the form of a box,
or in two pieces having a suitable channel to receive a loose metal
return tube, by preference of copper or brass. The bar is so formed
that the tube can be laid in the channel and bedded up with "rust” or
cement, or set in the channel loose. The ends of the tube are made to
project through the front end of the bar, thus forming projections or
nipples thereon. When the bar is made as a box the side of the bar is
covered over with a wrought or cast-iron plate, which is bolted or
_rivetted_to_the_bar_and_holds the metal tube and “rust or cement
packing in place. When the bar is made in corresponding halves
having suitable channels to receive the tube, such halves are bolted or
rivetted together with the tube in the centre. The front ends of the
bars are faced and made to butt up against a front bearer which may
have a ridge or flange cast on its under side to bear the weight of the
bars, or the weight may be borne by the bolt which secures the bar to
the front bearer. The bearer is made with a double channel or passage
way so arranged that one passage being the upper passage connects
with the upper portion of the tube, and the other passage or under
passage connects with the under portion of the tube in each bar. The
connection is made by the nipples formed by the tubes on the ends of
the bars taking into corresponding holes on the side of the bearer, the
bearer being faced to receive the ends of the bars, the joint being made
in any suitable manner. The bars are held up to the bearer by bolts or
studs which pass between the passage ways in the bearer, and screw
into the bars between the respective nipples formed by the ends of the
tubes. The bearer is made, by preference with its front open so that
the tubes can be got at for cleaning, the front of the bearer being
covered with a suitable plate or plates which are bolted or otherwise
attached thereto. The bearer is fitted with two branches provided with
suitable flanges, one branch opening into the under passage, and the
other branch opening into the upper passage. These branches are
provided with suitable valves and pipes so arranged that the water from
the boiler can be made to circulate through the bars, or the feed water
can-be-passed-through the bars as may be required, the principle
of circulation being similar to that described in the Specification of
Letters Patent before mentioned granted to me on 26th February
1872 No 611

page_text: tion, I will now proceed to describe more in detail how the same.may
be carried out into practical effect, and for that purpose I have hereunto
attached two Sheets of Drawings illustrative thereof. Like letters and
figures marked thereon are used to denote similar parts in the various
views.
Figures 1 to 8, Sheet 1 inclusive, illustrate my improved tubular.
water circulating fire-bar and connecting bearer in detail.
Figures 9 and 10, Sheet 2, illustrate a three furnace marine boiler,
fitted with water circulating fire-bars, connecting bearers, and parts
appertaining thereto according to my Invention.
•
Upon reference to Figures 1 and 2, Sheet 1, it will be seen that my
Invention consists of casting the bar A in the form of a box, or in two
pieces, as shown at Figures 3, 4, and 5. The bar A is formed with a
suitable channel a to receive a loose metal return tube B, by preference
of copper or brass. The bar A is so formed that the tube B can be
laid in the channel a, and bedded up with "rust” or cement, as shown at
Figures 1 and 2, or the tube may be set in the channel a loose. The
ends c, c', of the tube B are made to project through the front end of
the bar A, thus forming the projections or nipples c, c¹.
When the bar A is made as a box the side of the bar is covered over
with a wrought or cast-iron plate a¹ (sce Figure 2). This plate a' is
bolted or rivetted to the bar and holds the metal tube B and the "rust"
or cement packing in place..
When the bar A is made in corresponding halves as a³, a³, (see
Figure 5,) such halves are bolted or rivetted together with the tube B in
the centre.

The front ends D of the bars are faced and made to butt up against a
front bearer G which may have a ridge or flange (see Figure 1), cast
on its under side to bear the weight of the bars A, or the weight may
be borne by the bolts H which secure the bars to the front bearer G.
The bearer G is made with a double channel or passage way h, k, as
shown at Figures 1, 3, and 8. This double channel or passage way is so
arranged that the passage being the upper passage connects with the
nipple c, and the upper portion of the tube B and the under passage k
connects with the nipple c¹ and the under portion of the tube B of each.
bar. The connexion is made by the nipples c, c', of each bar taking
into corresponding holes on the side of the bearer G (see Figures 1, 3,

page_text: and 8). The side of the bearer G is faced to receive the ends of the
bars A, the joint being made in any suitable manner. The bars are held
up to the bearer by the bolts or studs H. The bolts pass between the
passage ways in tho bearer G, as shown in Figure 8. The bearer G is,
by preference, provided with a door or doors on its front side L, so that
the tubes B can be got at for cleaning. The bearer G is provided with
two branches M, N, the branch M opening into the passage k and
being the feed or supply passage to the bars, and the branch N opening
-into-the-passage-h-and-being-the feed or circulating passage from the
bars to the boiler.
Upon reference to Figures 9 and 10, Sheet 2, it will be seen that
Figure 9 is an end view of a marine boiler R with three furnaces V,
W, X. S is a feed valve with three distinct valve branches S¹, S³, S³;
T is the pipe from the feed pump of the engine attached to the valve S
by a suitable cock; U is an apparatus known as Lang's equaliser
constructed under Letters Patent, No. 4378, A.D. 1874, which is shown
in the Drawings connected by the pipe U¹ to the valve S and used for
circulating purposes as herein-after described. The valves S¹, S³, S³, are
respectively connected by the pipes t, t, t, to the branches M on the
bearers G. The pipes Y, Y¹, Y, lead from the branches N of the
bearers G to the cocks and mouth-piece Z which is placed at or above
the water line of the boiler R. Figure 10 is a section through ¸A, B,
Figure 9.
The principle of the water circulation through bars constructed
according to the beforegoing description is when the feed from .the
engine is at work, the main valve in the box S is closed and the bars
are fed through the valves S', S³, S³, through the pipes t, t, t, to the
passage of the bearers G. From thence the water passes through
the bars and is led through the passage 1 of the bearer, and the
pipes Y, Y, Y, into the boiler through the connecting piece Z,
the water being heated in its circulation through the bars. When
_the_feed_from_the_engine_through_the_pipe_T_is_shut_off_the_water_
is-fed-to the bars-A-by means of the circulator and equaliser U, tho
water circulating by means of the superior temperature of the water in
the bars over that in the bottom of the boiler from whence the supply is
taken.
Having now described the nature, object, and purposes of my Inven-
A not into nonatical offat T...

page_text: it to be understood that I do not confine myself to the precise details,
relative proportions, or dimensions of the improvements in tubular water
circulating fire-bars and connecting bearers, and parts appertaining
thereto herein-before described, as the same may be considerably varied
without departing from my Invention, but what I claim as my Invențion
and secured to me by Letters Patent, as aforesaid is,―
Firstly. Constructing a fire-bar, such as A in the form of a box
having a suitable channel, such as a to receive a loose metal returning
tube, by preference of copper or brass, such as B, and bedding up the
tube in the bar A with "rust or cement, and covering the bar with a
plate, such as a², substantially such as shown at Figures 1 and 2 of the
accompanying Drawings and described in the foregoing Specification.
"
Secondly. Constructing a fire-bar, such as A in two pieces, or corre-
sponding halves having a channel, such as a to receive a loose metal
returning tube, by preference of copper or brass, such as shown at
Figures 3, 4, and 5 of the accompanying Drawings, substantially as set
forth in the beforegoing Specification.
Thirdly. Constructing the bearer G with two horizontal passages,
such as h, k, communicating respectively with the supply and discharge
branches M, N, substantially such as shown in the accompanying
Drawings and described in the beforegoing Specification.
Fourthly. Constructing and applying tubular water circulating fire-
bars, connecting bearers, and parts appertaining thereto, substantially
such as shown in the accompanying two Sheets of Drawings in the
manner and for the purposes set forth in the beforegoing Specification.
In witness whereof, I, the said Robert Joseph Ellis, have here-
unto set my hand and seal, this Third day of March, in the
year of our Lord 1876.
