NONRAD TAMPER of Sicice, in the Empire of Russia, Manufacturer do hereby
declare the nature of this invention to be as follows:-
This invention more especially refers to steam boilers or generators, of locomotive
type (although the improvements hereinafter described may be adapted to steam
boilers of other types), the said improvements consisting in the construction, formation
and arrangement of the fire tube whereby it may be removed from the boiler in its
entirety without necessitating the removal of the boiler end or bottom.
According to my invention I form the fire tube of the boiler of conical form, and
oval; elliptical or an approximation thereto in cross section, and having flanges on
the ends by which it is fastened to the body or ends of the boiler, the back flange on
the smaller end of the fire tube abutting and being secured on the inside of the back
end of the boiler, and the front flange on the larger end of the tube abutting and being
secured on the outside of the front end. This opening in the front end of the boiler
for the admittance of the fire tube is of sufficient size to allow of the insertion of the
back flange, and by this arrangement after the bolts have been unfastened the fire
tube may be withdrawn without removing or displacing any part of the body of the
boiler.
The fire tube is provided with vertical boiler tubes of small diameter, and cylindrical
and by the oval formation of the fire tube section I am enabled to introduce a greater
number of these tubes than heretofore, and thus increase the heating surface, and these
vertically arranged boiler tubes also ensure an active and increased inter-circulation of
the flame.
By the oval section of the fire tube and the arrangement of boiler tubes therein,
the steam space is materially increased and the water space diminished which further
promotes the production of dry steam and diminishes the danger of explosion.

Improvements in Steam Boilers.
I, KONRAD GAMPER, of Sielce, in the Empire of Russia, Manufacturer 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:
This invention more especially refers to steam boilers or generators for locomotives
(although the improvements hereinafter described may be adapted to steam boilers of
other types) the said improvements consisting in the construction, formation, and
arrangement of the fire tube whereby it may be removed from the boiler in its
entirety, without necessitating the removal of the boiler end or bottom.
In order that my invention may be fully understood and readily carried into effect
I will describe same with reference to the accompanying drawings, Figure 1 being a
longitudinal vertical section of so much of a steam boiler as will be necessary to
explain my invention, Figure 2 is a vertical cross section taken through the line a
of Figure 1, and Figure 3 is a vertical cross section taken through the line y y' of
Figure 1.
C
According to my invention I form the fire tube c of the boiler a of conical form and
oval, elliptical, or an approximation thereto in cross section, an example of which is
shewn at Figures 2 and 3. The fire tube is formed or provided with flanges c¹, c²
on its ends by which it is fastened to the body or ends b, of the boiler; the back
flange on the smaller end of the fire tube c abutting and being secured on the inside
of the back end of the boiler, and the front flange c¹ on the larger end of the fire tube
abutting and being secured on the outside of the front tube.
The opening on the front end of the boiler for the admittance of the fire tube c is
of sufficient size to allow of the insertion of the back flange c², and by this arrangement
after the bolts have been unfastened the fire tube may be withdrawn without removing
or displacing any part of the body of the boiler.
The fire tube c is provided with vertical boiler tubes d which differ from the so
called "Galloway" tubes in that they are of smaller diameter and of cylindrical form,
and by the oval formation of the fire tube section c I am enabled to introduce a
greater number of these tubes d than heretofore, and thus increase the heating
surface, and these vertically arranged boiler tubes d also ensure an active and increased
inter-circulation of the flame.
.By the oval section of the fire tube and the arrangement of boiler tubes therein the
steam space is materially increased, and the water space diminished, which further
promotes the production of dry steam and diminishes the danger of explosion.

page_text: 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 :-
1. In steam boilers, the conically shaped fire-tube c provided with flanges c¹, c² so
formed that the interior portion of the said fire tube and the interior flange of same
may be inserted or withdrawn through the opening in the boiler and without
removing or displacing part or parts of the body of the boiler as herein set forth.
2. In steam boilers, the conical flanged fire tube c of oval or elliptical shape in cross
section or an approximation thereto and provided with boiler tubes d of cylindrical
form substantially as and for the purposes herein described and illustrated with
reference to the accompanying drawings.
