Improvements in Steam Generators for Road and other Vehicles.
THOMAS TOWARD, 26, Heaton Road, WILLIAM TOWARD, 59, Heaton Road, and
JOHN MEEK, 21, Heaton Grove, all of the City and County of Newcastle-on-
Tyne, Engineers, do hereby declare the nature of this invention to be as
follows:-
Our invention has for its object to provide a steam generator which is simple
in construction and relatively to the space it occupies, & its weight, contains
a large and well arranged heating surface without the necessity for objection-
able heating surface above the water line, while a ready access to the various
parts for cleaning or repairs can be had, & furthermore a perfect and rapid
circulation also a high generative efficiency can be easily obtained with an
entire absence of priming.
According to our invention as applied to the vertical inclined type, the boiler
is preferably rectangular in form & consists of two vertical tube plates spaced
the one from the other at suitable distance & connected to each other in the
lower portion by a series of small horizontal water tubes & screwed stay tubes,
and in the upper portion by a large horizontal tube which forms a drum or
steam receiver, the water level extending into it, all these tubes may be inclined
in one or different directions or horizontal.
Connected to each tube plate on its outside surface with a bolted joint is
an embossed or other door plate which forms a head or water space at each
end of the boiler, & connects the ends of the small tubes to the drum with
ample area, the door plates are readily removed when necessary giving access
to every part.
The top and sides are enclosed with a light steel casing which extends below
the boiler proper & forms the furnace, the latter is lined with firebrick, or where
lightness is not so much an object may be surrounded either wholly or par-
tially with a water space, and has the usual firebars, the heated gases from the
furnace pass upwards among the small tubes around the drum & thence to the
flue, which may be led straight upwards as a chimney or carried downwards
& discharged below the vehicle.
This method is also applicable to horizontal type boilers the tubes being
much longer & the heads or ends consequently much farther apart & the gasses
circulated by baffle plates amongst the tubes, the steam receiver being hori-
zontal.

THOMAS TOWARD, 26, Heaton Road, WILLIAM TOWARD, 59, Heaton Road, and
JOHN MEEK, 21, Heaton Grove, all of the County and City of Newcastle-on-
Tyne, Engineers, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement;-
Our invention has for its object to provide a steam generator, which is simple
in construction & relatively to the space it occupies, & its weight, contains a
large & well arranged heating surface, without the necessity for objectionable
heating surface above the water line, while a ready access to the various parts
for cleaning or repairs can be had, and furthermore a perfect & rapid circula-
tion, also a high generative efficiency can be easily obtained with an entire
absence of priming.
According to our invention as applied to the vertical inclined type, the
boiler is preferably rectangular in form, & consists of two vertical tube
plates P, P.
Figs. I & II, spaced the one from the other at suitable distance and con-
nected to each other in the lower portion by a series of small horizontal water
tubes T, & screwed stay tubes, & in the upper portion by a large horizontal
tube or tubes B, which form drums or steam receivers, the water level extending
into them, all these tubes may be inclined in one or different directions, or
horizontal.
Connected to each tube plate on its outside surface with a bolted. joint J,
is an embossed or other door plate D, D, which forms a head or water space S, S,
at each end of the boiler into which all tubes open, & connects the ends of the
small tubes to the drum with ample area, the door plates are readily removed
when necessary, giving access to every part.
The top & sides are enclosed with a light steel casing C, C, which extends
below the boiler proper & forms the furnace F, the latter is lined with fire-
brick L, or where lightness is not so much an object may be surrounded either
wholly or partially with a water space, & has the usual firebars, the heated
gases from the furnace pass upward among the small tubes around the drum &
thence to the flue E, E, which may be led straight upwards as a chimney, or
carried downwards & discharged below the vehicle.
In a modified form where lightness is necessary, the back end tube plate &
water space is dispensed with, a light perforated casing plate X. Figs. III & IV
being substituted, the back of the tubes, passing through the perforations a
sufficient distance to allow of deposit collecting without injury from the heat
of the furnace, the drum also passing through this plate, the small tubes are
thus perfectly free to expand or contract & each tube is provided with a cleaning
plug V, for removing deposit when necessary & may be fitted with or without
circulating tubes K."
The front water space S, is extended in capacity & fitted with a removable
door plate D.
This method is also applicable to the horizontal type boilers, the tubes being
much longer & the heads or ends consequently much further apart, & the
gases circulated by baffle plates amongst the tubes, the steam receiver being
horizontal.

page_text: Having now particularly described & ascertained the nature of our said
invention & in what manner the same is to be performed, we declare that what
we claim is:
(1) The manner of inclining of the whole body of the boiler to the proper angle.
(2) The manner of embossing & forming joint on the door plates at ends bolted
to the tube plates and recessed to form water chambers.
(3) The general arrangement of tubes, water spaces, & casings. All substan-
tially as described with reference to the drawings.
