Improvements in the Construction of Steam Boilers for Utilizing
Waste Heat from Puddling, Forge, Mill, or other Furnaces.
I, JAMES BEESLEY, of The Ridge Lane Mills, Lancaster, in the County of Lancaster,
Boiler Maker, do hereby declare the nature of this 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 horizontal cylindrical steam boilers of the kind for which
Letters Patent No. 3020 of 1886 were granted to William and James Beesley.
According to Beesley's said Patent the waste heat from puddling; forge, mill, or
other furnaces is first passed through a lower tube or flue and then returned through
two upper smaller tubes or flues.
This invention has for its object to construct a boiler of the kind referred to
so that it may have an increased area of heating surface, a larger draught way,
and less water space arranged in such manner that its construction may be simplified
and strengthened and greater facilities afforded for access to the internal parts of
the boiler.
In order that the nature of my improvements may be more clearly understood the
accompanying drawings are added.
Fig. 1 is a longitudinal vertical section;
Fig. 2 a plan view (partly in section);
Fig. 3 a cross section; and
Fig. 4 a back end view of a steam boiler constructed in accordance with my said
invention.
A is the outer cylindrical shell of the boiler; B a lower tube or flue; Can
upper tube or flue having transverse rows of Galloway tubes D D arranged in
alternate positions as shewn (see Figs. 1 and 2); E a box or chamber lined
with refractory material and fastened to the back end plate F of the boiler; and
Ga door for providing access to the end chamber E (hereinafter referred to as
the "return box"). The return-box E may, however, if preferred, be arranged to
be within the end of the boiler instead of outside thereof.
The waste heat is conducted from the puddling or other furnace through a suitable
flue to the inlet end H of the lower tube or flue D through which it passes into the
return box E, whence it returns through the upper tube or flue C (impinging in its
course upon the Galloway tubes D D) and is carried off through an outlet flue to a
chimney or smoke stack.
The sides of the upper tube Care of semi-cylindrical form so as to give
the tube greater strength and the upper and lower plates of the said tube are
curved and stand in a position concentrically with the axis of the lower tube B so as
to permit of the employment of Galloway tubes of a uniform length.
It will be observed that, whereas according to William and James Beesley's Patent
(bereinabove referred to) a lower and two upper tubes are employed, according to this
my present invention a lower tube and only one upper tube are employed; my single
upper tube, however, affords a greatly increased area of heating surface than is the
case with two upper tubes and is of such a form and size as to admit of the intro-
duction therein of a considerable number of Galloway tubes and consequently provides
a large additional heating surface of a more effective kind. Moreover the size and
form of my upper tube and its position relatively to the lower tube whilst it reduces
the water space facilitates access to every part of the interior of the boiler for cleaning
or other purposes.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
In a horizontal cylindrical steam boiler employed for the purpose set forth the
combination with a lower tube or flue of a single upper tube or flue shaped or formed
in cross section and arranged substantially as herein before described and shewn in the
drawings.
Dated this 2ord day of July 1890.
