PROVISIONAL SPECIFICATION.
Improved Construction of Ring Valves and their Seating Boards,
specially adapted for Organs.
I, FREDERICK ROTHWELL, of 5 College Terrace, Burrard Road, West
Hampstead, Middlesex, Organ Builder, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improved construction of ring valves and their seating
boards specially adapted for organs.
For the purpose of my invention, I make the valves in circular form with two
flat surfaces, and an annular hollow between the flats. The circular part is con-
nected by radial wings to a central eye, so that the valve proper can be centralized
by a pin, or rod for the necessary motion.
In some cases, two of such valves may be formed from the same piece of metal,
or other material and have one eye only.
The radial wings or arms are preferably dished, or shaped to a greater distance
to that of the raised hollows of the valves.
The valve seatings in the seating boards are prepared by boring holes to a given
diameter and then in saw cuts, or narrow planed grooves which I form across the
board, and also across the plugs, which I prepare to fit in the holes, I insert strips
on edge, which are retained in place by glue, or other method of fastening. By
this means I form annular passages in the boards for the valves, before described,
to cover. Around the holes of the board, I arrange the cushion or valve leathers,
which are shaped to correspond.
As an example of the use of my valves and seatings to an organ, I attach two
of the valves on a rod in a suitable manner, the end of which rod is affixed to a
diaphragm covering a chamber in direct communication with an air trunk in con-
nection with a finger, or the pedal key, so that by pressure on the key, or pedal, the
air acts upon the diaphragm and lifts, or closes the valves according to their
arrangement to allow the main volume of air to pass from the wind chest, and for
the exhaust to escape from an intermediate, or supplementary bellows.

COMPLETE SPECIFICATION.
Improved Construction of Ring Valves and their Seating Boards,
specially adapted for Organs.
I, FREDERICK ROTHWELL, of 5 College Terrace, Burrard Road, West
Hampstead, Middlesex, Organ Builder, 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 improved construction of ring valves and their seating
boards specially adapted for organs.

page_text: For the purpose of my invention and as shown in the annexed drawings, I make
the valves, Figure 1, in circular form with two flat surfaces A, A, and an annular
hollow B between the flats. The circular part is connected by radial wings C, C
to a central eye D, so that the valve proper can be centralized by a pin or rod E
for the necessary motion, see Figures 2 and 3.
In some cases two of such valves may be formed from the same piece of metal,
or other material, as at Figure 4, and have one eye only. The radial wings or
arms are preferably dished or shaped to a greater distance to that of the raised
hollows of the valves.
The valve seatings in the seating boards F are formed by boring annular grooves
to a given diameter, and depth and then by saw cuts or narrow planed grooves,
which I form across the board, and also across the plugs G, G, which are left from
the boring, I insert strips H on edge, which are retained in place by glue, or other
method of fastening. The boards are then reversed for the complete boring. By
this means,
I form annular passages in the boards for the valves before described
Around the holes of the board I arrange the cushion or valve leathers I which
are shaped to correspond.
to cover.
As an example of the use of my valves and seatings to an organ, see Figures 2
and 3, I attach two of the valves on a rod E in a suitable manner, the end of which
rod is affixed to a diaphragm J covering a chamber in direct communication with
an air trunk in connection with a finger, or the pedal key, so that by pressure on
the key or pedal, the air acts upon the diaphragm and lifts or closes the valves
according to their arrangement to allow the main volume of air to pass from the
wind chest and for the exhaust to escape from an intermediate or supplementary
bellows. I am aware of the Specifications of Letters Patent numbered respectively
15245 of 1890, and 15461 of 1890 granted to Robert Hope-Jones and I wish it to
be understood that I do not claim anything described and claimed therein.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The construction of valve or valves as herein before described and substantially
as shown on the annexed drawings for the purpose set forth.
2. The herein described method of making annular passages in valve boards of
organs and like instruments, and affixing the central plugs by cross strips
substantially as indicated by the drawings.
