JONATHAN GROVE, of Birmingham, in the County of Warwick, Manu-
facturer, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by
His Letters Patent under the Great Seal of Great Britain, bearing
date at Westminster, the Twenty-second day of October, in the thirty-
fifth year of His said Majesty's reign, did give and grant unto me, the
said Jonathan Grove, His special licence, full power, sole privilege
and authority, that I, the said Jonathan Grove, my executors, adminis-
trators, and assigns; and no others, should and lawfully might, during
the term of years therein expressed, use. exercise, and vend, throughout
that part of His Majesty's Kingdom of Great Britain called England,
the Dominion of Wales, and Town of Berwick-upon-Tweed, and also
in His Majesty's Colonies and Plantations abroad, my new Invention
or manufacture of "A GUN Lock OR LOCK FOR GUNS OR FIRE-ARMS OF A
NEW CONSTRUCTION;" in which said Letters Patent is contained a proviso,
whereby it was and is declared, that if I, the said Jonathan Grove,
should not particularly describe and ascertain the nature of my said
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 one calendar
month next and immediately after the date of the said Letters Patent,

page_text: that then the said Letters Patent should be void, as in and by the said
Letters Patent, relation being thereunto bad, may more fully appear.
NOW KNOW YE, that in compliance with the said proviso, and in
pursuance of the said Letters Patent, I, the said Jonathan Grove, do
hereby declare that the following is a particular description of the
nature of my said Invention and of the manner in which the same is
to be performed (that is to say):.
The letters A, B, C, D, in the Drawings a a 1, and a a 2, hereunto
annexed, represent the plate, cock, jaw, and cock pin, of the musquet
or gun lock, and are similar to those that are generally used in musquet
or gun locks, to the plate of which lock I fix the main spring E, de-
scribed in three different Drawings hereunto annexed, respectively
marked E, and also marked bb 3, 6 6 4, and 665, by inserting
the inside stud (m) in the said Drawing bb4, and bb 5, through the
plate, a corresponding opening being left in the latter to receive the
said stud; and I fix a pivot or stop through the plate in the said Draw-
ing a 2, marked F, to prevent the spring from overstraining when
cocked. G, in the Drawing a a 2, represents the tumbler, which is
further described in the two Drawings thereof c c 6, and c c 7, here-
´unto annexed; the axle tree of which tumbler I put through the centre
of the main spring above described, and through the axle tree of the
plate and cock, and which axle tree is fastened on the outside of the
cock by the screw marked H, in the said annexed Drawing a a 1, and
also marked II, in the first of the six small Drawings at the bottom of
the annexed plan. The outside stud of the main spring is dovetailed in
the tumbler and fastened to the tumbler by the screw marked Z, in the
said annexed Drawing represented between bb4, and 665. 1, in the
Drawing aa 1, and a a 2, represents the hammer or hen, and K, the
second of the six small Drawings below the screw, which fastens or
fixes the hammer or hen to the plate in the same manner as in common
musquet or gun locks, (see the Drawings a a 1, and a a 2); but the
heel of the hammer or hen instead of being turned up as in common
musquet or gun locks, is made strong and is turned down, and when
struck by the cock, falls upon and is stopped by the stud marked P,
which is screwed and rivitted in the plate, (see a a 1, and a a 2);
and also see great P, number 6, of the small Drawings at the bottom.

page_text: L, in tlie Drawing a a 2, and in the Drawings d d 8, and d'd 9,
represents the hammer or hen spring, at one end of which is a roller
marked N, in the Drawing a a 1, and in the said Drawings d d 8,
and dd 9, fastened by a collett marked (o) in a a 1, and dd 9, and
in the fourth of the sinall Drawings at the bottom; which hammer
or heu spring is fastened to the inside of the plate, by a screw marked
M, in the Drawing a a 2, and also in the fifth of the small Drawings
at the bottom. cc 10, and ee 11, are two Drawings of the trigger and
plate, in which Q, is the plate; and R, the trigger; S, the trigger pitt,
which fastens the trigger in the trigger plate, (sec also number 3, of
the 6 small Drawings at the bottom). X, in ee 10, is a screw which
passes through a hole X. in ee 11, and serves to secure the trigger
plate in its position. T, represents the trigger spring, which is
serewed in the inside of the trigger plate, by a screw marked U. The
two Drawings f f 12, ff 13, and also cach marked V, represent a
box of brass or other similar metal, to carry the pivot (p) of the tum-
bler, which is fixed in the musquet or gun stock, and is confined by the
screw marked W, which passes through the tail of the breech pin of
the musquet or gun barrel, and also through part of the said brass or
other metal box, and screws into the trigger to the stock under the
guard. Y, Y, represents two screws to fasten the lock to the musquet
or gun, in the same manner as in musquets or guns in general. When
the lock and the trigger and the trigger plate, so as above described in
the said annexed Drawings, are so fasteried to the musquet or gun
stock, the end of the trigger communicates through the said brass or
other metal box, and is received into the bents of the tumbler made for
the purpose of cocking, half cocking, and discharging the musquet
or gun.
In witness whereof I have hereunto set my hand and scal, this
