I, WILLIAM HOLT, of Bradford, in the County of York, Organ. Builder, dö
hereby declare the nature of the said Invention for." IMPROVEMENTS IN REED
PIPES FOR ORGANS to be as follows
:
Mys "Improvements in, Reed Pipes for Organs consist in the application of
a' pneumatic lever- or valve to the reed or tongue for producing quick speak-
ing," by 'acting upon a spring "or jack made of any suitable material, tipped
with india-rubber or any other flexible material, which strikes the:" reed.ör
tongue so as to produce instantaneous vibration: My claim is for the..appli
cation of the pneumatic lever or valve to "reed pipes.".

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Holt in the Great Seal Patent Office on the
16th September 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HOLT, of Bradford, in the County of York, Organ Builder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of March, in the year of our Lord
One thousand eight hundred and fifty-four, in the seventeenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Holt, Her special licence that I, the said William Holt, my
executors, administrators, and assigns, or such others as I, the said William
Holt, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise; and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN REED PIPES FOR
ÒRGANS," upon the condition (amongst others) that I, the said William Holt,
by an instrument in writing under my hand and seal, should particularly
describe and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said William Holt, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof (that is to say):-
My Invention consists in the application of a pneumatic lever or valve to
the reed pipes of organs in such manner that on the wind being admitted or
brought to bear upon the same it immediately expands or dilates, and by
means of suitable apparatus the reed or tongue is struck, thereby causing it to
vibrate instantly, the wind at the same time acting upon the reed keeps it in
vibration, as at present, during such period or space of time as the operator
desires. The object of this Invention is to cause the reed or tongue to speak
quickly, which object, is hereby successfully accomplished, and also a fuller,
rounder tone is obtained by having the reeds made of thicker metal than here-
tofore. The improvements will be clearly understood by any one conversant
with reed pipes as at present constructed, and the manner in which they are
acted upon. Instead of the reed or tongue being caused to vibrate solely by

page_text: the direct force of the wind, as at present, by my improvements vibration is
produced by the expanding or dilating of the pneumatic lever or valve by the
force of the wind, which by means of a spring or jack, made of any suitable
material, tipped with india-rubber or any other flexible material or substance
connected thereto, and placed in such position that when the said pneumatic
lever is forced out the spring or jack is drawn thereby; and made to pass,
striking the end of the reed or tongue in its passage, causing or producing
vibration, which is then kept vibrating by the direct action or force of the
wind, as at present..
Having thus fully explained the nature and particulars of my said Inven-
tion, I desire it to be distinctly understood that I do not confine myself to this
or any particular mode of applying the Invention or apparatus employed
therewith. But I claim as of my Invention, and which, to the best of my
knowledge and belief, is new within this realm, the application of the
pneumatic lever or valve to reed pipes.
In witness whereof, I, the said William Holt, have hereunto set my
hand and seal, this Thirteenth day of September, in the year of our
Lord One thousand eight hundred and fifty-four.
Witness,
JOSHUA H. RAWNSLEY.
WILLIAM HOLT. (L.S.)
