Brear, of Bradford, in the County of York, Plumbers and Gas Fitters, for the
Invention of "IMPROVEMENTS IN HOT WATER HEATING APPARATUS."
Sealed the 13th Santambor 1878 and dated the 4th April 1878.
PROVISIONAL SPECIFICATION left by the said William Henry Byram at the
Office of the Commissioners of Patents on the 4th April 1878.
WILLIAM HENRY BYRAM, Employé of Messrs. Walton and Brear, of Bradford, in
the County of York, Plumbers and Gas Fitters. "IMPROVEMENTS IN HOT WATER
HEATING APPARATUS."
This Invention relates to constructing water heating tubular boilers of an
improved form, whereby great heating surface is obtained with a free circulation of
the water, and requiring no brick work boiler setting.
For this purpose I construct a foundation frame, in which is fitted a bridge and
dead plate, and on which are fitted fire-bars; on the top of the foundation frame I
fit a chainbered waterway fire-box having a waterway partition which fits on the
top of the bridge, leaving a space in the back part of the fire-box forming a flue
leading to the outlet smoke pipe which is fitted in the back plates of the chambered
fire-box; this outlet pipe can be fitted with a boiler plate chimney, or the pipe may
be fitted to pipes leading to a brick chimney; feed pipes are fitted on each side of
the outlet smoke pipe and in the back chamber, the front chamber is made with an
opening, in which is fitted a frame and stoking or fire-door.
Over the chambered fire-box, and on the top, I fix a chambered waterway
frame, in which are cast or fitted a series of horizontal tubes or pipes; these tubes
are near the top of the frame; the front and back chambers in which the tubes or
pipes are fitted are made open, on which are fitted plates or doors to allow of the
cleaning of the tubes or pipes; the plates or doors are secured by bolts or nuts or
by set screws. The front waterway chamber is made with a curved recess, and
open at the top and bottom for the passage of the water from the chambered fire-

page_text: box to the chambered tubular frame; the front chamber of this frame is cast with
a feather or partition, closing one half of the chamber which allows the water from
the chambered fire-box to pass through one half the tubes or pipes fitted in
the frame, and to return through the other half to the front and pass on to another
chambered waterway tubular frame by outlet passages of similar construction to the
inlet passages hercin-before described.
Several similarly constructed chambered waterway tubular frames are employed,
fitted one over the other, and on the last one is fitted a chambered waterway cover,
having a curved top chamber; this cover is also made with an inlet passage, and a
hot water delivery pipe is fitted on the top.
The inlet and outlet passages are made water-tight by india-rubber rings placed
over the openings, and rings are cast under the water chambers which fit in the
india-rubber rings, keeping the rings in position.
On the outside side plates of the foundation frame fire-box chambered tubular
frames and cover are cast bosses, through which are passed rods fitted with nuts;
by screwing up the nuts over the top bosses the apparatus is firmly secured together,
and the india-rubber rings are pressed down, forming water joints.
I cover the apparatus with felt or any suitable material, and enclose the same
with wooden boards.
The fire, gases, and smoke travel up and round each set of horizontal tubes or
pipes, also on the inside surfaces of the fire-box, chambered tubular frames, and
cover; the gases and smoke descend through the back flue and escape through the
smoke pipe into the chimney.
By these means I construct a water heating boiler requiring no brickwork,
having large heating surfaces and a free circulation of water."

the said William Henry Byram in the Great Seal Patent Office on the 1st
October 1878.
WILLIAM HENRY BYRAM, Employé of Messrs. Walton and Brear, of Bradford, in
the County of York, Plumbers and Gas Fitters. "IMPROVEMENTS IN HOT WATER
HEATING APPARATUS."
The said Invention relates to constructing water heating tubular boilers of an
improved form, whereby great heating surface is obtained with a free circulation
of the water, and requiring no brickwork boiler setting.
For this purposes I construet a foundation frame, in which is fitted a bridge and
dead plate, and on which are fitted fire-bars; on the top of the foundation frame I
fit a chambered waterway fire-box, having a waterway partition which fits on the
top of the bridge, leaving a space in the back part of the fire-box, forming a flue
leading to the outlet smoke pipe which is fitted in the back plates of the chambered
fire-box or foundation frame; the outlet pipe can be fitted with a boiler plate
chimney, or the pipe may be fitted to pipes leading to a brick chimney;
feed pipes
are fitted on cach side of the outlet smoke pipe, and in the back chambers; the
front waterway chamber is made with an opening, in which is fitted a stoking or
fire-door.
Over the chambered fire-box, and on the top, I fit a chambered waterway frame,
in which are cast or fitted a series of horizontal tubes or pipes; the back chambers
in which these tubes or pipes are fitted or fixed are made open with plates or doors
to allow of the cleaning of the tubes or pipes; the back chambers of the frames
may be cast with feathers or partitions, closing part of the chambers so as to allow
the gases and smoke to travel up the front part of the tubular chambers, and
descend over the top feather to the back tubular chambers to the outlet pipe and
chimney.
Several similarly constructed waterway tubular frames are employed, fitted one
over the other, and on the last one is fitted a chambered waterway cover, which is
fitted with inlet pipes, and hot water pipes are fitted on the top of the cover.
I cover the apparatus with felt or other suitable material, and enclose the same
with wooden boards.
The fire, gases, and sınoke travel up and round each set of horizontal tubes or
pipes, also on the inside surfaces of the fire-box, chambered tubular frames, and
cover; the gases and smoke descend through the back flue and escape through the
smoke pipe to the chimney.
By these means I construct a water-heating boiler requiring no brickwork, having
large heating surfaces and free circulation of water.
But in order to enable my improvements to be bettor understood I will proceed
to describe the same by reference to the accompanying Drawing, in which Figure 1
represents a sectional front elevation of the improved water-heating tubular boiler;
Figure 2, sectional side view; Figure 3, front elevation; Figure 4, back elevation
Figure 5, sectional plan of the waterway fire-box; Figure 6, sectional plan of one
of the chambered waterway frames; and Figure 7, side elevation of the same.
Similar letters of reference are used in all the Figures to represent similar
parts.
;
A, foundation frame having a dead plate B and bridge C, on which are fitted
fire-bars D; on the top of the foundation frame is fitted a chambered waterway
fire-box E, in which is fitted a waterway partition F, leaving a space G, forming a
flue leading to the outlet smoke pipe H, which may be formed at the back of the
foundation frame or in the back plates of the fire-box; the outlet smoke pipe may
be fitted with a boiler plate chimney or with pipes leading to a brick chimney; the
front of the fire-box is made with an opening I, and over the opening are fitted
guides J, in which slide fire-doors K, which slide and open or shut by means of

page_text: the knobs L. On the top of the fire-box E is fitted a waterway chambered
frame M, in which are fitted or cast a series of horizontal tubes or pipes N;
four or more of these waterway chambered tubular frames M are fitted, one
over the other, and on the top of the last frame is fitted a chambered waterway
cover O.
The feed pipes are connected to sockets P, cast at the back of the fire-box
chamber; the feed water travels in the chambers of the fire-box to the front,
pressing through pipes Q to the front of the first chambered tubular frame,
travelling through the frame and tubes to the back, and passing through pipes R to
the second chambered tubular frame, and through the chambers and tubes to the
front, and thence through pipes S to the front of the third chambered tubular frame,
passing on through the chambers and tubes to the back, and through pipes T to the
front of the fourth chambered tubular frame, and through pipes U to the chambered
cover, and from thence through sockets V, cast on the top of the cover to discharge
hot water pipes. The back chambers of the tubular frames are fitted with doors
W, which are secured to the frames by studs and nuts; ribs ✗ are cast on the
doors to strengthen them; the doors are for the purpose of cleaning out the tubes
when required.
I may fit midfeathers Y in the chambered tubular frames to cause the fire, gases,
and smoke to travel up the inside of the frames, and pass over the top Z of the last
midfeather, and descend through the back chamber A to the chimney.
I may also construct apparatuses without the hollow partition or bridge F and
midfeathers Y; in this case I fit a boiler plate chimney on the top of the cover O,
or I fit pipes leading to a brick chimney.
The apparatus is covered with felt or any other suitable material, and enclosed
with wooden boards.
The fire, gases, and smoke travel up and round each set of horizontal tubes N,
also act on the inside surfaces of the fire-box and chambers, and on the inside
surface of the cover heating the water passing through the different chambered
passages and tubes, producing an effective heating boiler having large heating
surfaces and freo circulation of the water with a small consumption of fuel.
Having thus described my improvements, and the best means I am acquainted
with for carrying the same into effect, I would have it understood that I do not
confine myself to the precise details shewn and described, as these may be varied
without departing from the peculiar character of the Invention, but what I do claim
is, the general arrangement, construction, and employment of water-heating tubular
boilers made with independent chambered waterway horizontal tubular frames,
whereby great heating surface is obtained, with a free circulation of water, and
requiring no brick boiler setting, substantially as herein-before described and
represented by the accompanying Drawing.
In witness whereof, I, the said William Henry Byram, have hereto set my
hand and seal, this Thirtieth day of September, in the year of our
Lord One thousand eight hundred and seventy-eight.
