THE SAME TIME PRESERVING THE INSTRUMENT COMPLEAT," within that part of His
Majesty's Kingdom of Great Britain called England; His Dominion of Wales,

discretions seem meet; and that I, the said Samuel Gillespy, my executors,
administrators, and assigns, should.&. lawfully. might have and enjoy the

page_text: whole profit, benefit, commodity, and advantage from time to time coming,
growing, accrewing, and arising by reason of the said Invention, for and during
the term of years therein mentioned, to have, hold, exercise, and enjoy the said
licence, powers, privileges, and advantages therein-before granted or mentioned
to be granted unto me, the said Samuel Gillespy, my executors, administrators,
and assigns, for and during and unto the full end and term of fourteen years
from the date thereof next and immediately ensuing, and fully to be compleat
and ended according to the Statute in such case made and provided; in which
said recited Letters Patent is contained a proviso, that if I, the said Samuel
Gillespy, should not particularly describe and ascertain the nature of my said
Invention, and in what manner the same was to be performed, by an instrument
in writing under my hand and seal, and cause the same to be inrolled in His
said Majesty's High Court of Chancery within four calendar months next
and immediately after the date thereof, that then the said recited Letters
Patent, and all liberties and advantages whatsoever thereby granted, should
utterly cease, determine, and become void, anything therein-before contained
to the contrary thereof in anywise notwithstanding, as in and by the said
in part recited Letters Patent, relation being thereunto had, will more fully
and at large appear.
NOW KNOW YE, that I, the said Samuel Gillespy, do hereby declare
my said Invention, and declare that the same is to be performed in manner
following (that is to say)
The method of putting on the quills to affect the tone is, by applying two
mortices in the irons which draw the stops, by which means the quills may be
put on or off with the application of a peddle and swell, which raise the top
from any of the stops, bringing on the sound gradually or suddenly. This
peddle may be used with the top open or shut; by pushing on the brass
knobs at the bass end it effects a long mortice connected with the peddle and
swell. The method of putting on the quills by this peddle is by an application
of a lever and square, connected with springs of bog-bristle, whalebone, cane,
or wire, with a notch in the jacks, and cloth or leather to keep them silent
in their motion. By the assistance of these jacks, there is introduced a new
celestial stop composed of wood, metal, or wire, screwed at both ends, with
heads of taned leather, buff leather, kid leather, cloth, and wood, to compleat
the said heads, by which the above-mentioned celestial tone is effected or
produced, and the harpsichord is rendered more compleat than any now extant.
The frame for carrying the motion, which gives the blow to cause the celestial
sound, is or may be composed of wood and metal, or either, with springs
thereto, made of brass or steel wire, to assist the motion. The manner of

page_text: connecting the celestial stop with the jacks is by pushing it in or pulling it out,
on the principle of a shifting or fixt mortice, or on an unison harpsichord.
The first row of jacks may be used in the motion connected with the celestial
stop, or a false jack may be introduced on such a principal as may affect the
said celestial motion; or the motion of the celestial stop may be hung with
leather, parchment, or cloth, to the back of the frame, for its centre of action;
or the keys may be constructed in such a manner as that each may receive
the next note by adding the thickness of one key at the side of another, so
that the jack for C may come on the B key, C being tuned to B, making the
unisons (the two springs nearest together), or the jack of the key C be
brought aslant to the under sockett, so as to fall on the key of B; C then
tuned to B, making the unisons.

Faith, and so forth, and in the year of our Lord One thousand seven
