page_text: JOSEPH Moss, Millwright 33 Bruce Grove, Nottingham WILLIAM MOSS,
Engineer 16 Thorney wood Lane, Carlton Road Nottingham do hereby declare
the nature of this invention to be as follows:-
In the improved types of our said Invention, we adopt a much more simple
system of construction than has hitherto been introduced. The cost of production
being materially lessened, whilst at the same time friction is reduced to a minimum
and the reliability and durability of such apparatus as the above referred to are
also greatly increased.
In Rotary Engines, Pumps or water motors constructed according to our
Invention the piston employed is of an eccentric or other form suitable to the
work to be performed. The abutment works in a slot on the outer case of the
cylinder the end of which projects into a chamber open to the action of steam, air,
gas, or fluid which keeps the face of said abutment in contact with the eccentric
or other formed piston, effectually dividing the steam from the exhaust.
The supply of steam, air, gas or fluid entering the cylinder is regulated by the
dise valve working on the cylinder cover on the outer face of which an expansion
valve or disc can be placed so as to give any amount of expansion required and is
worked by hand or automatically.
The Engine is reversed by opening the cock supplying the steam, air gas, or
fluid to either end of the cylinder one end causing the piston to revolve in one
direction the other causing the piston to revolve in a contrary direction, at the
same time opening or closing the exhaust ports to work in unision with the same,
thus reversing the direction of the piston without any other arrangement being
required.
They can also be made non reversing by having only one inlet and one exhaust,
the said exhaust being always open and without a plug as required in those made
for reversing.

This Engine is used as an air or water motor in the same manner as described in
using steam.
To convert the same into a pump it is only necessary to fix an inlet valve on the
steam opening L and a delivery valve on the exhaust opening M.
We do not confine ourselves to the precise details shewn but may modify them
without departing from the principles of our invention.
Having now described the nature of our said invention and in what manner the
same is performed we declare that what we claim Provisional protection for is
1st. The manner in which the abutment A, is kept in contact with the piston,
by the pressure of steam, air, gas or fluid, pressing on the stem of the said
abutment in chamber C, or by other mechanical means.
2nd. The employment of the disc valve F for the admission of steam, air, gas or
fluid, and means employed for cutting off the same at any part of its revolution.
3rd. The employment of an expansion disc valve at the back of valve F to cut
off at any part of a revolution by hand or automatically.
4th. The mode of exhausting and the manner of opening & closing the same.
5th. The manner in which the reversing is performed by the admission of steam,
air, gas or fluid at either end of cylinder according to the direction in which the
piston K is desired to revolve.

JOSEPH Moss, Millwright, 33 Bruce Grove, Nottingham WILLIAM MOSS,
Engineer, 16 Thorneywood Lane, Carlton Road Nottingham we do hereby
declare the nature of our invention for IMPROVEMENTS IN ROTARY STEAM, AIR
OR WATER ENGINES, ROTARY PUMPS" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
In Rotary engines, or pumps constructed according to our invention the piston
employed is of an eccentric or other form suitable to the work to be performed.
The abutment works in a slot in the outer casing of the cylinder the end of which
projects into a chamber open to the action of steam, air or fluid which keeps the
face of the said abutment in contact with the eccentric or other formed piston thus
effectually dividing the steam, air or fluid as the case may be from the exhaust.
The supply of steam, air or fluid entering the cylinder is regulated by the disc
valve working on the cylinder cover on the outer face of which an expansion valve
or disc is placed to cut off the supply of steam, air or fluid as required, and is
worked by hand or automatically.
The engine is reversed by opening the cock supplying the steam, air or fluid to
either end of the cylinder according to the direction in which the piston is desired
to revolve, at the same time opening or closing the exhaust port to work in unison
with the same thus reversing the direction of the piston without any other
arrangement being required.
They can also be made non reversing by having only one inlet and one exhaust
the said exhaust being always open and without a plug, as required in those made
for reversing.
To convert the same into a pump it is only necessary to fix an inlet valve at the
opening, and delivery valve to the outlet, due provision by means of rings and
strips are also provided where necessary to prevent the waste of steam, air or
fluid or the escape of the same through the working parts.
In the improved types of our said invention we adopt a much more simple
system of construction than has hitherto been introduced. The cost of production
being also materially lessened, whilst at the same time friction is reduced to a
minimum, and the reliability and durability of such apparatus as the above refered
to are also greatly increased.
Referring now to the accompanying drawings of which sheets 1 & 2 were filed
with the provisional Specification.
Figure 1 is a longitudinal sectional elevation of one of our apparatus according
to our invention arranged as a Rotary Steam Engine.
A, is the abutment which seperates the inlet of steam, air or fluid entering the
said apparatus from the outlet.

L. Is the opening for the admission of steam, air or fluid to the cylinder one of
these being placed on each cover at opposite ends of cylinder and is so arranged
that by the opening of one end gives motion to the piston in one direction, and by
closing the same and opening the opposite end gives motion in a contrary direction
thereby reversing the same.
M. Is the exhaust ports which are so constructed as to be able to close either of
them according to the direction in which it is desired the piston shall revolve, this
effected by plugs in each port and are so actuated that the closing of one opens
the other.
Figure 3, is a sectional elevation of one of our apparatus, showing the manner in
which the ends of the piston are constructed whereby we dispence with the valve
or disc marked F in figure 1.
The piston has a groove or port cut in each end of the same and at the same
radius as the inlet in cylinder covers and communicating with the interior of
cylinder as shewn, the groove or port being cut so as to give steam, air or fluid
any part of a revolution desired, the reversing of the same being' effected as
described in Figures 1 and 2.
Figure 4, is a sectional elevation shewing steam, air or fluid inlet in cylinder
covers and which are the same radius as groove or port in piston ends.
Figure 5, is a plan of cylinder cover shewing openings so arranged as to be able
to work expansively.

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;
1st. The manner in which the abutment A is kept in contact with the piston K
by the pressure of steam, air or fluid pressing on the top of the said abutment in
chamber B.
2nd. The valve or disc F for the admission of steam, air or fluid and means
employed for cutting off at any part of a revolution.
3rd. The employment of an expansion valve N at the back of valve F to give a
variable cut off as required.
4th. The mode of exhausting & closing or opening of exhaust ports.
5th. The mode in which the reversing is performed by the admission of steam,
air or fluid at either end of the cylinder according to the direction in which the
piston K is desired to revolve.
6th. The mode in which the disc or valve is dispensed with by making the faces
of piston ends form the valve for the admission of steam, air or fluid and the
application of an expansion valve on the cylinder covers to give a variable amount
of steam, air or fluid as required and to be worked by hand or automatically as
may be desired, see Figures 3, 4, 5, 6 & 7.
We do not confine ourselves to the precise details shewn but may modify them
without departing from the principle of our invention.
