PROVISIONAL SPECIFICATION.
Improvements in Steam Generators.
I, THOMAS BEELEY, of Hyde Junction Iron Works, Hyde in the County of
Chester, Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates particularly to the steam boilers well known in the trade
as the Fairbairn-Beeley boilers and the objects of my improvements are to inoronso
the area for draught and the heating surface of the boiler and to overcome the
injury sustained by expansion and contraction of the tubes.
In order to increase the area for draught and the heating surface of a Fairbairn-
Beeley boiler I make the last tube of the furnace flue that is the one in front of
the small tubes of an enlarged diameter so as to obtain a greater area for a larger
number of small tubes and I connect this tube of enlarged diameter to the front
part of the flue preferably by a taper tube. The small tubes in place of being
straight are according to my improvements preferably ourved or bent so that any
expansion or contraction of the tubes causes them to bond instead of loosening the
joints at the end plates and I prefer to dispense with some of the small tubes
near the bottom of the tube plates and insert a single tube of say, ten inches in
diameter which gives greater facility for cleaning out dirt from the far end of
the boiler.
My improvements can be applied to either single or double Fairbairn-Beeley
boilers.
Dated this 12th day of November 1895.

Improvements in Steam Generators.
I, THOMAS BEELEY, of Hyde Junction Iron Works, Hyde, in the County of
Chester, Engineer, 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 particularly to the steam boilers well known in the trade
as the Fairbairn-Beeley boilers and the objects of my improvements are to increase
the area for draught' and the heating surface of the boiler and to overcome the
injury sustained by expansion and contraction of the tubes.
In order to increase the area for draught and the heating surface of a Fairbairn-
Beeley boiler I make the last tube of the furuace flue that is the one in front of
the small tubes of an enlarged diameter so as to obtain a greater area for a larger
number of small tubes and 1 connect this tube of enlarged diameter to the front
part of the flue preferably by a taper tube. The small tubes in place of being
straight are according to my improvements preferably curved or bent so that any
expansion or contraction of the tubes causes them to bend instead of loosening the
joints at the end plates and I prefer to dispenso with some of the small tubes

page_text: near the bottom of the tube plates and insert a single tube of say, ten inches in
diameter which gives greater facility for cleaning out dirt from the far end of
the boiler.
My improvements can be applied to either single or double Fairbairn-Beeley
boilers.
The accompanying drawing illustrates the preferred mode of applying my
improvements to a Fairbairn-Beeley boiler.
In this view, a b designate the end plates in which are fixed any convenient
number of small curved or bent tubes c as well as a single straight tube d of a
larger diameter. In front of and secured to the end plate a is an enlarged tube e
of the same diameter or thereabouts as the end plate and secured to the tube e is
the larger end of a taper tube which at the smaller end is secured to the tube g
of the furnace flue.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In a Fairbairn-Beeley boiler-
1. The combination with the furnace flue and' the small tubes at the rear end of
the flue, of an enlarged tube such as e connected to the flue and' to the small tubes
in the manner herein set forth or in an equivalent manner.
2. The combination with the furnace flue, of the small curved tubes c either
with or without the single straight tube & substantially as herein set forth.
