PROVISIONAL SPECIFICATION.
Improvements in Steam Boilers.
We, ROBERT GRAY MORTON, of Errol, in the County of Perth, North Britain,
Engineer, and CHARLES JOSEPH FINDLAY, of 40, Henrietta Street, Glasgow,
in the County of Lanark, North Britain, Engineer, do hereby declare the nature of
this invention to be as follows, that is to say:-
Our said invention relates to steam boilers of a portable, semi-portable, or
locomotive class, suitable for agricultural and other purposes, and our object is by
an improved construction to admit of such boilers being conveniently transported
in separate parts, in localities in which heavy or bulky articles cannot be easily
conveyed.
In carrying out our invention we make the steam boiler of the locomotive type,
with a barrel having tubes through it, a firebox at one end and a smokebox at
the other end; and we make the three parts named separable from each other.
For attaching the barrel to the firebox we rivet to the front end of the barrel
an angle-iron ring presenting a flat flange to make a joint against the back vertical
plate of the firebox and when the parts of the boiler are put together the ring is
fixed to the firebox plate by screw bolts. The smokebox is made to fit upon or
within an enlargement riveted to that end of the barrel.
The tubes are, according to one modification, arranged to have their front ends
fixed in a tube plate in the usual position in the firebox, the ends being detached
from such plate when the parts of the boiler are separated for transport.
According to another modification both tube plates are fixed to the barrel, and
the firebox water space is shaped to form a communication between the interior of
the firebox and the tubes when the boiler is put together. Suitable communications
are made by pipes or otherwise between the firehox water space and the barrel
water space.
In addition to our improved construction rendering the boiler more conveniently
transportable, it allows of thorough internal inspection and cleaning.

COMPLETE SPECIFICATION.
Improvements in Steam Boilers.
We, ROBERT GRAY MORTON, of Errol, in the County of Perth, North Britain,
Engineer, and CHARLES JOSEPH FINDLAY, of 40, Henrietta Street, Glasgow, in
the County of Lanark, North Britain, 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, that is to say :-
-
Our said invention relates to steam boilers of a portable, semi-portable, or
locomotive class, suitable for agricultural and other purposes, and our object is by
an improved construction to admit of such boilers being conveniently transported
in separate parts, in localities in which heavy or bulky articles cannot be easily
conveyed.
In carrrying out our invention we make the steam boiler of the locomotive type,
with a barrel having tubes through it, a firebox at one end, and a smokebox at
the other end, and we make the three parts named separable from each other.
And in order that our said invention and the manner of performing the same may

page_text: be properly understood we hereunto append a sheet of explanatory drawings to be
hereinafter referred to and showing three modes of carrying out our invention.
Figure, 1, of the drawings is mainly a longitudinal vertical section of a boiler
with the firebox part, F, and the smokebox, S, separated from the barrel, B, the
firebox part being partly in elevation.
Figure, 2, is a sectional elevation of the inner side of the firebox part, F.
Figure, 3, is a longitudinal vertical section mainly of the barrel part, B, and
showing a second modification of some parts.
Figure, 4, is a view like Figure, 1, but showing a third modification of some
parts.
In these drawings the same reference, letters are used to mark the same or like
parts wherever they are repeated.
For attaching the barrel, B, to the firebox part, F, (as shown in Figures, 1,
and, 2,) we rivet to the front end of the barrel an angle-iron ring, R, presenting a
flat flange to make a joint against the back vertical plate, A, of the firebox part,
and when the boiler is put together the ring, R, is fixed to the plate, A, by screw
bolts. The smokebox, S, is made to fit upon (or it might be within) an enlarge-
ment, formed on the plate, C, at that end of the barrel, B, or otherwise fixed to the
barrel. The tubes, T, may be fixed in the end plate, C, their front ends being
detached from the firebox tube plate, D. Or, as shown in Figure, 3, the smoke-
box ends of the tubes, T, may be fixed in a separate tube plate, E, which, when
the boiler is put together, is bolted to the end plate, C, of the barrel, B. Or again,
as shown in Figure, 4, the firebox ends of the tubes, T, may be fixed in a separate
tube plate, G, which when the boiler is put together is bolted to the back vertical
plate, H, of the firebox, the smokebox ends of the tubes being fixed in the end
plate, C, of the barrel.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
The improved construction of steam boiler, the same being made of the locomotive
type with the firebox part and smokebox separable from the barrel, and with
provision for connecting the parts substantially in the manner and for the purposes
herein before described.
