A Dictionary of Music and Musicians/Jones, Henry and Sons
Appearance
JONES, Henry & Sons, organ-builders in London, established 1847; they made the organs for Christ Church, Albany Street; St. Matthias, West Brompton; and the Aquarium, Westminster. They invented an ingenious composition pedal, under the influence of which any stops may be brought on by a turn of the stop-handle to the right; so that any possible combination, prepared but an instant before it is wanted, may be brought on to, or taken off, the keys.
