Improvements in Compound Rotary Engines,
I, LUDFORD CHARLES DOCKER, of the Birmingham Varnish Works, Rotton
Park Street, Birmingham, in the County of Warwick, Varnish Manufacturer,.
do hereby declare the nature of this invention to be as follows:-
:-
This invention refers to double-disc compound rotary engines. The engine
consists of two or more cylinders having covers fitted with suitable stuffing boxes
and glands through which pass two parallel shafts carried outside the cylinders
on suitable bearings; keyed on these shafts or made solid with them are double-
disc blades, two in each cylinder, these blades being fitted with rings of any
suitable form for the purpose of making a steam-tight joint.
Each cylinder has formed on one side a steam chest. A communication between
the cylinder and the steam chest is on one side, through a direct passage and on
the other side through a pipe or passage carried round the cylinder. Into the
first cylinder of the series the steam is led direct from the steam chest, which is
connected to the boiler by means of a pipe and afterwards from one cylinder to
another through the exhaust passage in each steam chest, which is connected by
means of a pipe to the steam chest next in series.
The steam from the boiler enters the high pressure cylinder, and after revolv-
ing the disc blades half a revolution is exhausted into the second cylinder and
afterwards to any subsequent cylinder, and is finally exhausted into the atmos-
phere or into a condenser in the usual way.
For reversing the engine the ordinary Ď valve is used. worked by any suitable
lever or gearing, steam, or other vapour, gas, or liquid under pressure may be
applied to disc blades and cylinders constructed as above described in order to
obtain power from the same.

to be performed, to be particularly described and ascertained in and by the
following statement:―
This invention refers to double disc compound rotary engines. Reference
should be had to the accompanying sheets of drawings, upon which the similar
letters of reference relate to similar parts on the various figures.
On Sheet 1.
Fig. 1 is a side view of an engine in part elevation and part vertical section.
Fig. 2 is a plan of same, and
Fig. 3 is an end elevation of same.
On Sheet 2,
Fig. 4 is an elevation of one of the shafts with the blades attached.
The remaining Figs. are drawn to a larger scale.
Fig. 5 is a section through one of the shafts shewing in elevation the disc
blades mounted thereon.
Fig. 6. is a half section and half front elevation of one of the pistons or disc
blades.

Fig. 9 is a sectional view through one of the steam chests on line X-X (see
Fig. 8).
Fig. 10 is a view of the steam chest with the cover R removed and the valve P
broken off to expose the chest.
The engine consists of two or more cylinders of the form shewn on the draw-
ings, which illustrate an engine consisting of three cylinders A, A1, A2 having
covers B fitted with suitable stuffing boxes C and glands D through which pass
two parallel shafts E, E¹, carried on suitable bearings F, outside the cylinders..
Keyed on to these shafts E, E¹ or made solid with them are double disc blades G,
G¹, Ga two in each cylinder shewn in Fig. 8 and in detail in Figs. 4, 5, 6 and 7,
these blades being fitted with rings H (see Fig. 6) of the form shewn or any
other suitable form for the purpose of making a steam tight joint.
Each cylinder has formed on one side a steam chest J. The interior arrange-
ment of each cylinder and steam chest being the same as illustrated by Fig. 8.
A communication between the cylinder and the steam chest is on one side
through a direct passage K and on the other side through a pipe or passage L
carried round as shewn in the drawing.
Into the first cylinder of the series A the steam is led direct from the steam
chest J which is connected by means of the pipe M to the boiler, and the steam
is afterwards led from one cylinder to another through the exhaust passage N
in each steam chest which is connected by means of a pipe O Fig. 2 to the steam
chest next in series. The steam from the boiler enters the high pressure cylinder,
and after revolving the disc blades half a revolution is exhausted into the second
cylinder and so on afterwards to the third or any subsequent cylinders and is
finally exhausted through the pipe $ into the atmosphere, or into a condenser
in the usual way.
For reversing the engine an ordinary D valve P (Fig. 8) is used worked by
any suitable lever or gearing Q (see Figs. 1 and 2).
By arranging the blades G, G1, G2, as shewn and described any necessity to
gear the shafts together is obviated.
Steam or any other vapour, or gas, or liquid under pressure may be applied for
working these engines.
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
I claim is
1. The use of two or more disc blades G, G1, G2 keyed to, or solid upon one
shaft, placed in rolling contact with a similar number of blades of the same form

page_text: attached to a second shaft, parallel to the other one, the two shafts passing through
two or more cylinders and the relative angles of the blades to each other so
arranged as to obviate the necessity of gearing the shafts together.
2. The application of steam, or any other vapour, or gas, or liquid under
pressure, to disc blades and cylinders of the form described and shewn in the
accompanying drawings in order to obtain power from the same.

ment of each cylinder and steam chest being the same as illustrated by Fig. 8.
