Improvements in Accordions or Melodeons.
JAMES POLLOCK BROWNE, Musicseller, Seventy-seven Jamaica Street, Glasgow
in the County of Glasgow, Scotland do hereby declare the nature of this invention
to be as follows:-
The main object of my invention is to provide an improved keyboard for
accordeons or melodeons so as to simplify the construction and repairing of these
instruments and consists of a separate or loose fitting top to the keyboard which
may be either fitted in a sliding dovetail slot or may be fitted with hinges so as to
give easy access to the keys and key springs, to simplify the renewing and
replacing of the key springs and also the numbering in consecutive order the
vibrators or tongues so that the vibrators or tongues may be made or tuned
separately and when broken may be replaced by a person not skilled in the repairing
of said instruments by simply selecting a vibrator or tongue of the same number as
broken one.

JAMES POLLOCK BROWNE, Musicseller, Seventy-seven Jamaica Street, Glasgow
in the County of Glasgow, Scotland 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 :-
The main object of my invention is to provide an improved keyboard for
accordeons or melodeons so as to simplify the construction and repairing of these
instruments, and consists of a separate or loose fitting top to the keyboard which
may be either fitted in a sliding dovetail slot or may be fitted with hinges so as to
give easy access to the keys and key springs, to simplify the renewing and replacing
the keyboard springs, and also the numbering in consecutive order the vibrators or
tongues so that the vibrators or tongues may be made or tuned separately, and
when broken may be replaced by a person bot skilled in the repairing of said
instruments by simply selecting a vibrator or tongue of the same number as
broken one.
Figure 1 Sheet 1 shews an improved keyboard, a of accordeon or melodeon top,
shews the ten pallets or levers of keyboard, c shews the movable stops for
regulating the wind supply, d shews the sliding dovetailed top, partially open in
drawing, shews the spiral springs, Fig. 2f shews the position of the spiral
spring in keyboard, Fig. 3 g shews a hinged top for keyboard, Fig. 4 shews
the reverse side of keyboard, i shews the plates containing the tongues
or vibrators, K shews the consecutive numbering of the tongues or vibrators
shews the reverse side of stops as shewn and described in Fig. 1 c, Fig. 5 m is a
vibrator or tongue.
It will be obvious that in order to replace a broken spring or springs it will only
be necessary to remove the sliding top or hinged top 9.

page_text: When it is required to replace a broken vibrator or tongue you have only to
remove melodeon or accordeon top aand select a vibrator or tongue m of the
desired number.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
1st. An improved keyboard for accordeons or melodeons.
2nd. An improvement in the arrangement of the vibrators or tongues in
consecutive order of numbering.
