PROVISIONAL SPECIFICATION.
Improved Disc Engines, particularly suitable as Water Meters.
I, WALTER GEORGE KENT, of 199, 200 and 201 High Holborn, in the County
of Middlesex, Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to the details of construction of what are known as disc
engines that is to say engines consisting of a so called cylinder (really a portion of
a sphere lying between two parallel planes) with conical ends pointing inwards and
having an inlet port at one side and an outlet port at the other side of a radial
partition and containing a disc or more usually a flat cone (called the piston)
slotted to receive the partition and which rocks about spherical bearings formed at
the apices of the conical ends of the "cylinder."
I form the outer case of the engine of two hollow cylindrical castings each closed
at one end and flanged at the other so that they can be bolted together. The
lower casting has on the outside two sockets at opposite ends of a diameter to
receive the inlet and outlet pipes. The inlet socket is connected by a passage to
an opening in the flat bottom of the casting. This opening is provided with a
grating and is surrounded by a flat face. The outlet passes direct from the inside
of the cylindrical casting. The "cylinder" or working chamber is made in two
parts the spherical portion and one conical end being cast in one piece, the other
conical end or cover being separate.
The
The first mentioned piece is flanged at its top the flange fitting into and making
a tight joint with a socket at the top of the lower half of the outer case.
inlet port of the "cylinder" is connected by a passage to an opening in the bottom
such opening being surrounded by a flat face which comes against the flat face of
the opening in the bottom of the lower half of the outer case one or other of these
faces being grooved to receive a packing ring to make a tight joint between them.
The outlet port from the "cylinder" is a mere hole leading to the space between
the outside of the "cylinder " and the inside of the lower half of the outer
case. The cover of the "cylinder" drops into a seat in the lower half. It and
the "cylinder" are kept in place by a flange upon the upper half of the outer case.
The cover has a central hole in it to allow the axial spindle of the piston to pass
out to operate the counting mechanism which is contained in the upper half of the
outer case. It will thus be seen that the fluid does not enter the upper half of the
outer case but is confined to the lower half and the "cylinder" within it.
Slots are formed in the spherical wall and in the lower coned end of the
"cylinder" to receive the edges of the partition which projects downwards along
one side of the outlet passage and is secured by a screw at the bottom.
Dated this 5th day of June 1893.

COMPLETE SPECIFICATION.
Improved Disc Engines, particularly suitable as Water Meters.
I, WALTER GEORGE KENT, of 199, 200 and 201 High Holborn, in the County
of Middlesex, Manufacturer, 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 relates to the details of construction of what are; known as disc

page_text: engines that is to say engines consisting of a so called cylinder (really a portion of
a sphere lying between two parallel planes) with conical ends pointing inwards and
having an inlet port at one side and an outlet port at the other side of a radial
partition and containing a flat or coned disc (called the piston) slotted to receive
the partition and which rotates about spherical bearings formed at the apices of
the conical ends of the "cylinder."
Figure 1 is a longitudinal vertical section of a meter constructed according to
this invention.
Figure 2 is a plan of the same with the covers removed.
Figure 3 is a plan of the cover.
Figure 4 is a plan of the cylinder cover.
Figure 5 is a plan of the piston.
Figure 6 a plan of the grid.
Figure 7 is a side elevation of the cylinder and
Figure 8 a section of the line X X Figure 7.
I form the outer case of the engine or meter of two hollow cylindrical castings a
and beach closed at one end and flanged at the other so that they can be
bolted together. The lower casting a has on the outside two sockets or flanged
end a a² at opposite ends of a diameter to connect to the inlet and outlet pipes.
The inlet a' is connected by a passage to an opening a³ in the flat bottom of the
casting. This opening is provided with a grating a' (shown separately at Figure 6)
and is surrounded by a flat face. The outlet a² passes direct from the inside of
the cylindrical casting. The "cylinder" or working chamber is made in two parts
the spberical portion c and one conical end being cast in one piece, the other conical
end or cover d being separate.
The first mentioned piece has a flange c¹ at its top fitting upon and making a
tight joint with the top of the lower half a of the outer case. The inlet port c² of
the "cylinder" is connected by a passage c³ to an opening in the bottom such
opening being surrounded by a flat face which comes against the flat face of the
opening in the bottom a of the lower half of the outer case a packing ring e being
provided to make a tight joint between them. The outlet port c from the
"cylinder" is an opening in the cylinder wall leading to the space between the
outside of the "cylinder c and the inside of the lower half a of the outer case.
The cover d of the "cylinder" (shown separately at Figure 4) drops on to a seat
on the lower half c. This cover and the "cylinder" are kept in place by a flange b¹
upon the upper half of the outer case. The cover d has a central opening in it to
allow the axial spindle of the piston f (shown separately at Figure 5) to pass
out to operate the counting mechanism g which forms no part of this invention and
which is contained in the upper half 6 of the outer case.
Slots Figure 7 are formed in the spherical wall and in the lower coned end
of the "cylinder" to receive the edges of the partition which projects downwards
along one side of the outlet passage as shown in Figure and is secured by
screws h¹ entering holes c c Figure 7 in the wall of the cylinder c.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is :-
1. The part a with its inlet terminating in a flat face substantially as described.
2. The part c with an opening in its bottom connected by a passage to the inlet
port substantially as described.
3. The combination of the parts a b c and d substantially as described.
4.. The method of fixing the partition h substantially as described.
5. Disc engines substantially as described and shown in the drawings.
