"The collar may or may not be circular, 
for this invention does not go at all to the 
sl;ape of the collar, or to the manner of 
fcnnirig it, but simply to the mode of 
joining the pipes by means of a collar. 
DAVID LOESCHMAn’s, (nEWMAN- 
STREET, LONDON,) foT Iniprovancnts 
in the Musical Scales @f Ke^ped Instru-- 
■ments with fixed Tunes. 
This invention is thus described : the 
scale of a piano*forte, or organ, on the 
contmon principle, having twelve sounds 
witliin the octave, is now' extended to 
twenty-four distinct sounds, which ena¬ 
bles the performer to play in thirty-three 
perfect keys, eighteen major, and fifteen 
miiior thirds. This is effected by means 
of six pedals, that cause the hammers to 
act upon twenty-four distinct sets of 
strings or unisons. Three pedals bring 
on the flats to the treble; and the like 
Dumber bring on the sharps to the bass. 
Every pedal has a separate movement 
and spring, which act independently of 
the key: on each movement are fastened 
two of the twelve hammers belonging to 
each octave throughout the compass; so 
that a pedal for the flats brings on two 
additional flats in each octave, and in 
like manner a pedal for the sharps brings 
on in eneb octave two additional sharps; 
when such additional flats or siiarps are 
no longer wanted, by omitting the use of 
the pedal, the spring belonging to it im¬ 
mediately leaves the movement to its po¬ 
sition or fixed tones of three sharps, two 
fiats, and seven natural tones, in each oc¬ 
tave. The mechanism for the flats and 
sharps is so constructed, that, if more 
sharps or flats are wanted than one pedal 
will produce, a second without the first 
will be sutficient to bring on two of each 
in addition. In organs the improvement 
is effected also by six distinct pedals, and 
in each octave there are twenty-four dis¬ 
tinct sounds, from twenty-four distinct 
pipes; there is a separate movement and 
spring to every pedal. Every fixed key 
has two stickers, two black-falls, and 
two pallets, which act on, two pipes of 
different sounds. Three of the six move¬ 
ments are fixed in the middle of the front, 
above the keys, and bring on the sharps 
to the back of the organ, and the same 
number are fixed in the like directions be¬ 
hind to bring on the flats towards the 
front. By fixing all the six movements 
in the middle of the front above the keys, 
or in the same situation behind, the de¬ 
sired efl'ect is produced.
