PROVISIONAL SPECIFICATION.
Improvements in Corliss Valves for Steam or other Engines.
WILLIAM DEEBLE FERGUSON Albert Villa Ravenhill Road Belfast Engineer
do hereby declare the nature of this invention to be as follows:-
:-
My invention relates to cylindrical valves having a partial rotary or reciprocating
movement within a cylindrical casing and which are commonly known as "Corliss
valves" and provides means of overcoming the difficulty hitherto experienced in
making Corliss valves having double or multiple ports to be completely steam tight
which difficulty arises from the necessarily extended proportionate circumferential
length of the bearing surface of Corliss valves when designed to cover two or more
ports. By my invention I provide a spindle axial with the chamber of the valve
and having projections or drivers thereon, arranged radially and in positions
suitable to the position of the ports in the cylindrical casing.
Mounted on each driver or series of drivers is a valve suitably arranged to work
against inside of casing in connection with the port desired to be opened or closed,
each port having its own valve and driver or series of drivers. The said valves
have a movement upon the said projections or drivers in directions radial from the
axis of the spindle to the inside face of the cylindrical casing, the movement
of each valve being independent of the radial movement of the other valve or
valves.
What I accomplish by my invention is that I greatly diminish the proportionate
circumferential length of the bearing surface of the valve or valves and thus
facilitate these being made completely steam tight, and in case of wear each valve
will, by its own independent radial motion on its driver or series of drivers
still preserve a close & steam tight fit against the inside surface of the cylindrical
casing.

I 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:-

positions suitable to the position of the ports D in the cylindrical casing.
Mounted on each driver or series of drivers is a valve E suitably arranged to
work against inside of casing in connection with the port desired to be opened or
closed each port having its own valve and driver or series of drivers, the said

movement of each valve being 'independent of the radial movement of the other
valve or valves.
What I accomplish by my invention is that I greatly diminish the proportionate
circumferential length of the bearing surface of the valve or valves and thus
facilitate these being made, completely steam tight and in case of wear each valve
will by its own independent. radial motion on its driver or series of drivers still
preserve a close and steam tight fit against the inside surface of the cylindrical
casing.
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
Corliss valves for multiple ports made in the manner and for the purpose shewn
and described having two or more independent valves in one casing, one valve for
each port but all driven by the same spindle.
