PROVISIONAL SPECIFICATION.
A New or Improved Construction of Locomotive Engine.
I FREDERICK CHARLES WINBY of Dover House Clifton Hill Brighton in the County-
of Sussex, Civil Engineer do hereby declare the nature of this invention to be as
follows
--
This invention relates to a certain new or improved construction of locomotive ongino
the object being to apply the construction of boiler specified for under the Specification
of my application for Letters Patent No. 17287 dated 31st October 1889.
In carrying this invention into effect I construct the boiler with a shell formed of
segments of a circle intersecting at an intermediate point in the height and jointed
together from side to side across the hoiler by a cross tie-plate forming the chord of
the segments.
With this duplo-cylindrical construction of boiler body I am enabled to introduce in
the space between the engine wheels a greater number of tubes. The firebox is made
up to the additional height, afforded by the boiler body and consequently I obtain a
greater heating surface by the increased number of tubes and also increased size of
fire-box.
I also increase the grate surface proportionately, in length. I apply cylinders of
greater capacity and aun enabled to supply them with the necessary increased quantity
and pressure of steam.
This construction enables me to provide a locomotive engine of greatly increased.
power.

COMPLETE SPECIFICATION.
A New or Improved Construction of Locomotive Engine.
I, FREDERICK CHARLES WINBY of Dover House Clifton Hill Brighton in the County
of Sussex, Civil Engineer, 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:-
This invention relates to a certain new or improved construction of locomotive engine
in which I use my improved boiler constructed as described in the Specification filed
under my application for Letters Patent No. 17287, dated 31st October 1889, in com-
bination with my improved fire box constructed as hereinafter described, and in order
that my invention and the manner of carrying it into effect may be fully understood I
will now describe the same with reference to the annexed drawings.
Fig. 1, is a longitudinal vertical section of a locomotive engine fitted according to
this invention.
Fig. 2, is a horizontal half section of the engine at the line of the centre of the axles.
of the wheels.
Fig. 8, a half plan partly in section.
Fig. 4, a half cross section at centre line of the smoke box and cylinder.
Fig. 5, half section of the boiler body at the line of the leading driving wheels.
Fig. 6, half section of the fire box looking on to the boiler tube plate.
Fig. 7, halt elevation of the fire box and foot plate.
A, is the upper segmental portion of the boiler-body and A¹, is the lower
segmental portion which will be mounted upon substantially the usual engine
framing as from the following particular descriptions and drawings of my improved

page_text: construction will clearly appear to any ordinary and competent locomotive engineer.
B, is the transverse chord-tie-plate; C the fire box space, which is increased in
height to the extent shown above the horizontal line of the tie-plate B, as indicated
by the double arrow line C¹.
C, is the crown of the fire-box.
D, is the fire-box tube-plate which is increased in area to receive the additional
number of tubes E, as indicated in the drawings between the said double arrow
line C", and the boiler-tubes E, extending between the fire-box-tube-plate D, and
the smoke-box-tube-plate F. (sen Figs. 1 and 6). G, is the water casing on the
sides back and end of the fire-box.
The steam cylinders are indicated at H, Figs. 2, 3, & 4.
In the construction of the fire-box the lower portion of the boiler body is
extended into the fire space at K, (Fig. 1) which, whilst maintaining the requisite
proportional length of grate surface affords further heating surface by reason of
increased length of boiler tubes.
The tube plate D, is fitted between the fire-box crown C, and the plate G³, of
the boiler shell at K. L, is a fire-brick arch to baffle the direct action of the
flames upon G'.
The extension plate G³, is provided with circulation openings M, forming communi-
cation with the water-casing-space G, around the fire-box.
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
1 claim is―
First The improved construction of locomotive engine in which are employed
the improved boiler and improved fire-box constructed and arranged with the
working parts as described and shown in the annexed drawings.
Secondly-The use in a locomotive engine of an inwardly projecting boiler
such as is shown in Figs. 1 and 6 in combination with a fire-box arranged sub-
stantially as described.
