improvements in Steam Engines.
We, HENRY WORMALD and JAMES HARGREAVES, both of the firm of The Leeds
Engineering and Hydraulic Company, Balm Road, Leeds in the County of York,
Mechanical Engineers do hereby declare the nature of this invention to be as
follows:-
According to our invention we place the cylinders within the boiler steam space,
thus producing economy in working, by preventing condensation in the cylinders
through the non-exposure of such cylinders to the atmosphere.
When two or more are used we operate the slide valves from one eccentric on the
fly wheel shaft.
We enclose the whole of the working parts, except the ends of the fly wheel shaft,
in a box, so that the engine can be worked without danger to the attendant, at the
same time presenting a neat and compact appearance.

Improvements in Steam Engines.
We, HENRY WORMALD and JAMES HARGREAVES both of the firm of the Leeds
Engineering and Hydraulic Company, Balm Road, Leeds in the County of York,
0 Mechanical Engineers, 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 :-
According to our invention we place the cylinders within the boiler steam space,
thus producing economy in working, by preventing condensation in the cylinders

page_text: In the accompanying drawings Fig. 1 is a transverse section and Fig. 2 a plan
shewing an arrangement of compound engine and boiler constructed and applied in
accordance with our invention.
In the drawings we have shewn a boiler A of the vertical type and of ordinary
construction. An opening B is provided in the top of such boiler to receive the
cylinders C and D which are flanged at E for the convenience of resting on the top of
the boiler to which they may be bolted or rivetted as may be preferred.
The smaller cylinder C is the high pressure cylinder and the larger cylinder D is
the low pressure cylinder, each being provided with their respective pistons F and G,
and are connected or engaged with the cranks H and I on the fly wheel shaft J by
means of their connecting rods K and L. The steam chests M and N are by
preference placed between the cylinders C and D, provided with slide valves O and P,
these slide valves being actuated from eccentric R through eccentric rods S and T
and valve spindles U and V. The stuffing boxes W and X for the valve spindles U
and V are of ordinary construction.
We enclose the whole of the working parts above referred to, except the ends of the
fly wheel shaft J in a box or cover Y so that the engine can be worked without
danger to the attendant, at the same time presenting a neat and compact appearance.
In the side of the box or cover Y are provided the bearings 1 and 2 for the fly
wheel shaft J, these being of ordinary construction. The throttle valve 3 shewn in
plan at Fig. 2 also the governors 4 and other parts of the engine not described and.
shewn, are of ordinary construction and operate in the usual way.
In connection with the above arrangement of boiler and engine, an ordinary double
acting pump 5 may be employed and actuated from an eccentric 6 on the fly wheel
shaft through eccentric rod 7. Any suitable safety valve 8 may be employed and
placed in any convenient position with regard to the boiler.. The chimney or flue 9
may be also placed in any convenient position.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is :-
The arrangement and application of the cylinder or cylinders of steam engines
within the steam space of boilers, substantially as herein set forth, for producing
economy in working of such engines.
Dated this 26th day of July 1887.
