page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
SEPTIMUS HYDE WOLLASTON; of Clapton, in the County of Middlesex, Merchant,
send greeting.
WHEREAS His most Excellent Majesty King George the Fourth did, by
His Letters Patent under the Great Seal of that part of the United Kingdom
of Great Britain and Ireland called England, bearing date at Westminster,
the Fourth day of June, in the Third year of His reign, give and grant unto
us; the said Henry Septimus Hyde Wollaston, my exors, adñññors, and assigns,
His especial licence, full power, sole privilege and authority, that I, the said
Henry Septimus Hyde Wollaston, my exors, admors, and assigns, during the
term of years therein mentioned, should and lawfully might make,. use, exercise,
and vend within England, Wales, and the Town of Berwick-upon-Tweed,.my
Invention of "A BOLT OR FASTENING, PARTICULARLY APPLICABLE AS A NIGHT BOLT;"
in which said Letters Patent there is contained a proviso, that if I, the said
Henry Septimus Hyde Wollaston, shall not particularly describe and ascertain
the nature of our Invention, and in what manner the same is to be performed,
by an instrument in writing under my hand and seal, and cause the same to be
inrolled in His Majesty's High Court of Chancery, within two calendar
months next and immediately after the date of the said Letters Patent, that
then the said. Letters Patent, and all liberties and advantages whatsoever
thereby granted, shall utterly cease, determine, and become void, as in and by
the same, relation being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Henry Septimus Hyde Wollaston, do hereby declare that the nature of my

page_text: said Invention, and the manner in which the, same is to be performed, are
particularly described and ascertained in and by the Drawings hereunto
annexed, and the following description thereof, (that is to say):-
My said Invention consists in a bolt or fastening so constructed, that when
fixed on a door post a bolt or tongue may be projected from it across the
opening of the door; or drawn back from that position at pleasure by means of
a wire or line connected with a weight contained therein; and it is so contrived as
to remain steady in either position by means of a counterpoise, similar to that
applied to other night bolts. There are various ways in which this may be
effected, but that which appears to me the best is represented in the
annexed Drawings. No. 1 shews the bolt itself, on which may be seen a
pin a, by which it is to be moved horizontally forwards or backwards. No. 2
represents a weight with an oblique groove b, c, in which the pin a of the bolt
slides, so as to move the bolt outwards or inwards according to the position of
the weight. No. 3 shews the case in which the bolt and weight are contained,
laid open for the purpose of letting them be seen in their proper situations.
No. 4 is the cover of the case, having attached to it two small bars to guide
the motion of the bolt.
In witness whereof, I, the said Henry Septimus Hyde Wollaston, have
hereunto set my hand and seal, this Seventeenth day of July, in the
year of our Lord One thousand eight hundred and twenty-two.
