Wo, GEORGE MARIE CAPELL, of Passenham Rectory, Stony Stratford, in the
County of Northampton, Clerk in Holy Orders, and JOHN SMITH RAWORTH, of
No. 24, Kirkstall Road, Streatham Hill, in the County of Surrey, Electrical
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 :-
This invention is for an improved combination of a steam engine, in which a piston
vibrates in a cylinder through an arc about the axis of the said cylinder, with a
dynamo electric machine, in such a manner that the engine and dynamo together only
occupy the same amount of floor space as the dynamo alone.
In carrying our invention into effect we mount the cylinder or cylinders of the
engine on the frame or field magnet of the dynamo, the vibrating crank or cranks of
the engine overhanging the dynamo and being connected by a rod or rods with a
crank or cranks on the shaft of the dynamo.
In order to relieve the bearing of the dynamo from the direct strain of the engine,
we couple the crank shaft of the engine with that of the dynamo by an adjustable
link.
By preference, we use a double crank on the dynamo. This is properly balanced
and provided with a short prolongation of the shaft on the side furthest from the
dynamo. This short piece of shaft is coupled to the end of the engine shaft
(prolonged for that purpose) by the adjustable link aforesaid. We do not confine
ourselves to this position of the link, inasmuch as it may be placed between the
crank and the dynamo.
When two engines are used, we use two links; or one triangular link with three
bearings, one for the crank shaft, and two for the engine shafts.
In order that our invention and the means by which the same is to be carried into
practical effect may be thoroughly understood, we will now proceed to describe the
saine in detail, referring in so doing to the accompanying figures which are to be
taken as part of this specification and read therewith.

page_text: Fig. 2 is a side elevation.
a is the dynamo-frame; b, the armature; c, the dynamo shaft; e, the engine
cylinder, the engine shaft, and g, the adjustable link by which the two shafts,
viz., that of the engine and that of the dynamo are coupled for the purpose explained
above.
We wish it to be distinctly understood that we do not, according to our invention,
confine ourselves to the relative positions of engine and dynamo as illustrated,
inasmuch as it is evident that the purpose of our invention would be achieved by
placing the engine under the dynamo.
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:-
1. The combination of a steam engine, in which a piston vibrates in the cylinder
through an arc about the axis thereof, with a dynamo electric machine, substantially
as and for the purpose herein before described with reference to the accompanying
figures.
2. The combination of a steam engine, in which a piston vibrates in a cylinder
through an are about the axis thereof, a dynamo electric machine, and a link adapted
to relieve the dynamo-bearing from the direct strain of the engine, substantially as
Thereinbefore
forth.
