Complete Specification Left, 16th Sept., 1896-Accepted, 26th June, 1997
gaus.
1 SAMUEL JENKINSON, of 45 Hampstead Road, in the County of London,
Organ Builder, do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements in the reed board of reed organs,
and is more especially applicable for producing the effect of a coupler in the
last octave towards the treble end of the instrument.
According to this invention, in any organ where space allows (especially in one
and two row organs), I fit an extra octave or extra octaves of reeds, between
the front of the reed board and the plunger rods, and I operate the same by
a second set of palletis or valves with plungers operated by the corresponding
keys and a suitable action. Thus each key in the last octave will operate two
plungers at the same time, each of which opens a pallett, without the keys
being extended.
The extra set or extra sets of reeds may be brought into action by means of
the coupler stop or by separate stops if desired.
By extending the extra reeds, plungers and palletts all along or partly along the
instrument, extra effects may be produced.
Dated this Twenty-ninth day of June 1896.

1 SAMUEL JENKINSON, of 45 Hampstead Road, in the County of London,
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 certain improvements in the reed board of reed organs,
and is more especially applicable for producing the effect of a coupler in the last
octave towards the treble end of the instrument. It is more particularly applicable
for use with small instruments, where the method of producing the effect of an
octave coupler, described in the Specification of my previous Letters Patent,
No. 3115 of 1894 is undesirable on account of its expense.
According to this invention, in any organ where space allows (especially in one
and two row organs) I fit an extra octave or extra octaves of reeds, between the
front of the reed board and the plunger rods, and I operate the same by a second
set of palletts or valves with plungers operated by the corresponding keys and a
suitable action. Thus each key in the last octave will operate two plungers at the
same time, each of which opens a pallett without the keys being extended.
The extra set or extra sets of reeds may be brought into action, by means of
the coupler stop or by a separate stop or stops if desired.
And in order that my said invention may be more clearly understood, I will
Price d

page_text: now proceed to describe the same with reference to the drawings accompanying
this specification, in which
Figure 1 is a plan of a part of an organ with some of the keys removed,
shewing key board, ordinary coupler, and my extra octave coupler,
Figure 2 is a plan of extra octave coupler detached, Figure 3 is an end view of
said extra coupler,
Figure 4 is a detail hereinafter referred to.
The same letters of reference are employed to denote the same parts in all the
views.
A shews the keys, B the key frame, B₁ shews the key pins, C the octave coupler,
D the extra octave coupler, a, a are the ends of the levers a¹, coming directly
under the pins b, on the keys A of the last octave at the treble end. c is a hinged
support to these levers. This hinged support e overlaps the ordinary coupler C,
so that when the latter is raised, and put into action by means of the coupler stop,
the former turns on its hinges d, d, bringing the ends a of the levers a¹ into contact
with the pins b, the other ends e, e of the levers a', are directly above the plungers f, f
which when depressed open the pallets g, g (see Figure 3) h Figs. 2 and 3 shews
a stop piece.
It will be seen that if the ordinary coupler stop be drawn out, the extra octave
coupler will be brought into action, and if one of the keys of the last octave be
depressed, the action of the corresponding lever al and plunger f will cause one of
the palletts to be opened in the extra octave of reeds.
The mutes 1, 1 to the extra reeds are opened in the following manner :-
The rods from the stops which actuate the mutes on the ordinary reed board
are extended so as to also operate the levers i and k (Figs. 2, 3 and 4); or are
connected to the said levers for the same purpose.
Thus, when these ordinary stops are drawn out, the lever i and the end k¹ of
the lever k are raised, thus opening the mutes 11: the end of the lever k pressing
upon the free end of the metal strip m attached to the mute, as will be seen on
reference to Figs. 2 and 4.
The extra octave coupler D is attached by hooks n, n to the key-board B.
Wind is supplied to the extra reeds by means of an india rubber tube,
extending from the top of the ordinary reed board to the under part of the
extra octave, at the extreme treble end. The position of the hole for receiving
this tube is shewn at c-Figs. 1 and 3.
In a one or two row organ (i.e. an organ having one or two rows of reeds) the
extra octave or extra octaves of reeds can be built as part of the ordinary reed
board, and operated without the use of levers a', by simply opening the palletts
of the extra octave by the direct action of the keys upon the plungers. These
reeds are brought into action either by the coupler stop or by a separate stop.
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 improvements in or relating to reed organs, substantially as set forth.
2. A reed organ provided with an extra set of reeds, in tone one octave higher
than the highest octave represented on the key board, placed between the front
of the reed board and the ordinary plunger rods, under the front part of the
keys, and connected at will to the keys of the said octave, substantially as set
forth.
