IMPROVEMENTS IN VERTICAL STEAM BOILERS
Year: 1884

page_text: I JONATHAN COOK JOPLING of Sunderland in the county of Durham, Manu-
facturer do hereby declare the nature of the said invention for " IMPROVEMENTS IN
VERTICAL STEAM BOILERS to be as follows:-
»
The improvements herein referred to are applicable to vertical boilers, the object
of the invention being to augment the area of heating surface, facilitate cleansing
and repairs with increased facilities for the free circulation of the water.
The following description of the invention aided by the accompanying drawings
will clearly illustrate its nature.
Fig 1 is a sectional elevation of a boiler embodying my invention. Fig 2 being
a section of the same.
The fire is enclosed in a circular chamber or fire box A, which is surrounded by
water at the sides B and top C, the fire from this inner chamber passes into the
two circular flues D. D', one on each side of this chamber, and thence into the
uptake E, into the funnel F. The water surrounds these flues as well as the inner
chamber A.
'
The water spaces B, can be easily cleaned out from above and any deposit of
mud removed through a mud hole situated near the bottom of the boiler in any
position desired.
Vertical water tubes H, may be placed if required in the return flue of the boiler
as shown in the section Fig 2.

page_text: I JONATHAN COOK JOPLING of Sunderland in the county of Durham, Manu-
facturer do hereby declare the nature of the said invention for IMPROVEMENTS IN
STEAM BOILERS, 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:—
The improvements herein referred to are applicable to vertical boilers, the object
of the invention being to augment the area of heating surface, facilitate cleaning,
and repairs, with increased facilities for the free circulation of the water.
All the parts of the boiler, that is to say the outer shell, both sides of the flue,
as well as the inner or combustion chamber being of circular form, and forming
concentric circles, the boiler thus constructed is of exceptional strength, expansion
being very regular and equal.
The accompanying drawings aided by the following description will fully explain
the method adopted for effecting the objects of the invention in the most efficient
and practical form.
Fig 1 is a sectional elevation of a boiler embodying my improvements. Fig 2
being a section through the line G. H. of Fig 1. The same letters of reference
indicate like parts in the respective figures.
•
The fire is enclosed in the inner or combustion chamber A, the fire hole C¹ which
is of the ordinary construction for vertical boilers is fixed by rivetting or other
convenient method customary with such boilers, and is situated near the bottom of
the boiler a little above the fire bars C, or in any other position that may be
deemed expedient or suitable; the flame and gases of combustion pass from the
inner chamber. A or fire box through an opening D see Fig 1 & 2, formed by a ring
as shown by the-drawing, into the circular fluo D' D", which latter surrounds the
inner or combustion chamber A; a water space B, intervening between the two.
The flame dividing takes two courses, one part passing through one half D¹ of
the flue, the other passing through the other half D" of the flue, and meeting at
the outlet or uptake E to the funnel F.
•
This opening E may be constructed in the same manner as the ring or, opening D
Fig 1 & 2 from the combustion chamber, or any other manner that may be useful
or convenient.
The water surrounds the combustion chamber A; and the circular flue D¹ D¹, in
the spaces B & B, at the top C, and bottom of the flue. The water spaces B. B¹.
being vertical can readily be cleaned from above, the boiler being provided with a
manhole at the top, side, or any convenient position. Any deposit or mud, may be
taken out from a mud hole or holes situated at the bottom of the boiler; as is
usual in vertical boilers.
The advantages of this principle of construction are, the increased area of heating
surface; the essential characteristic of the invention being the circular form of the
Huo in conjunction with the other parts, whereby additional strength is obtained,
expansion being very regular and equal.
.
The form and combination of the circular flue with the inner or combustion
chamber conduce greatly to the consumption of the gases and smoke, and a more
free circulation of the water is insured, the water spaces being easily cleaned;
deposits falling below the level of the fire bars.
Vertical water tubes H, may be placed if desired in the circular or return
flue D D. for increasing the heating surfaces.
It may also be found advantageous to place an air tube H' in the boiler in the
position as shewn by drawing fig 1 for the more complete combustion of the gases.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is notably the circular or return fluo D¹ D", leading from the inner or
combustion chamber A. to the funnel F, in conjunction with the openings D & E,
and the water spaces B. B¹. with the addition if required of vertical water tubes H
in the circular or return flue D₁ D", and air tube H admitting air into the
flue D' D" in the position as shewn by drawing for the better consumption of the
gases; for effectually carrying out the objects of the invention as herein expressed
and as illustrated by the accompanying drawings.
Dated this 24th day of October 1884.
