Improvements in the Tubes or Flues and Shells of Boilers or other
Vessels Employed for Generating Steam and for other Purposes.
I DANIEL ADAMSON, of Dukinfield, in the County of Chester, Engineer, do hereby
declare the nature of said Invention for IMPROVEMENTS IN THE TUBES OR FLUES AND
SHELLS OF BOILERS OR OTHER VESSELS EMPLOYED FOR GENERATING STEAM AND FOR
OTHER PURPOSES, to be as follows:-
:-
The object of my Invention is to strengthen the tubes or flues and shells of boilers
or other vessels that they may withstand compressive and expansive force and expand
or contract longitudinally according to the variations of temperaturo to which they
are subjected. This has not hitherto been accomplished without forming on the tubes
or flues. hollow recesses or corrugations. which collect dirt and scale deposited by the
water.
In carrying my Invention into effect I take a solid tube and flange both the ends
outward at one operation. The flanges form a convenient means for riveting welding
or otherwise securing the tubes together in the manner described in the Specification
to Letters Patent No. 14259 granted to me and Leonard Cooper on the 12th day of
August 1852. I form by preference the inner part of each flange of special shape to
allow the joint to be effectively and easily caulked from the inside. without necessi-
tating the employment of an intermediate ring. I curve the tube outward in one or
more places around its periphery so as to form a ring or rings out of the solid tube
all the surface of the tube between the flanges except these rings being left plain or
straight.
In applying a cross or conical tube to one of my improved tubes I secure the
cross or conical tube into the plain or straight part of my improved tube preferably
between the rings by welding or riveting or in other convenient manner.
My improvements are applicable to tubes and flues and are equally applicable to the
shells of marine, locomotive and other boilers and other vessels, which have to sustain
great pressure.

I DANIEL ADAMSON of Dukinfield in the County of Chester Engineer, do hereby
declare the nature of said Invention for IMPROVEMENTS IN THE TUBES OR FLUES
AND SHELLS OF BOILERS OR OTHER VESSELS EMPLOYED FOR GENERATING STEAM AND
FOR OTHER PURPOSES, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
The object of my Invention is to strengthen the tubes or flues and shells of boilers
or other vessels that they may withstand compressive and expansive force and expand
or contract longitudinally according to the variations of temperature to which they
are subjected. This has not hitherto been accomplished without forming on the tubes
or flues hollow recesses or corrugations which collect dirt and scale deposited by the
water.
In carrying my Invention into effect I take a solid tube and flange both the ends
outward at one operation. These flanges form a convenient means for rivetting
welding or otherwise securing the tubes together in the manner described in the
Specification to Letters Patent No. 14259 granted to me and Leonard Cooper on the
12th day of August 1852. I form by preference the inner part of each flange of
special shape to allow the joint to be effectively and casily caulked from the insido
without necessitating the employment of an intermediate ring. I curve the tube
outward in one or more places around its periphery so as to form a ring or rings out
of the solid tube all the surface of the tube between the flanges except these rings
being left plain or straight.
In applying a cross or conical tube to one of my improved tubes I secure the
cross or conical tube into the plain or straight part of my improved tube preferably
between the rings by welding or rivetting or in other convenient manner.
My improvements are applicable to tubes and flues and are equally applicable to
the shells of marine locomotive and other boilers and other vessels which have to
sustain great pressure.
And in order that my Invention may be fully understood and readily carried into
effect I will describe the accompanying Sheet of Drawings reference being had to the
figures and letters marked thereon.
Figure 1 represents in sectional elevation a boiler tube flue or shell a made
according to my Invention by the machine described in the Application for Letters
Patent No. 535 of even date herewith or by any other suitable machine.
This tube flue or shell a has flanges a¹ and solid rings or annular projections a³ on
its periphery instead of corrugations or hollow recesses as now customary.
The tube may be flanged at one end only if required and one or any other suitable
number of rings or annular projections may be formed thereon.

page_text: Figure 2 represents in sectional elevation part of a similar tube but in this
caso made with a specially shaped flange so as to form at a a caulking space or
surface.
Figure 3 is a sectional view showing the adjacent onds of two of the tubes with
specially formed flanges as shown in Fig. 2. This view shows clearly that by means
of the caulking space a³ the joint can be effectively and easily caulked from the
inside by a plain caulking tool without the intervention of an intermediate ring.
It is obvious that the flanges of plain corrugated or other tubes besides those of my
improved tubes may be specially formed with a caulking space or surface as shown
and described.
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―
1. A tube flue or shell having flanges at both ends or at one end only and a solid
ring or rings on its periphery substantially as and for the purposes herein described
and as illustrated by Figure 1.
2. A tube flue or shell formed with a solid ring or rings on its periphery and
having specially shaped flanged ends formed for caulking purposes substantially as
herein described and as illustrated by Figures 2 and 3.
3. A tube flue or shell having flanged ends of special configuration to form a
caulking space or surface substantially as described with reference to Figures 2
and 3.
