Year: 1818

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
MATTHEW COTES WYATT, of Henrietta Street, Cavendish Square, in
the Parish of Marylebone, in the County of Middlesex, Esquire, send
greeting.
WHEREAS His most Excellent Majesty King George the Third
did, by His Letters Patent under the Great Seal of the United King.
dom of Great Britain and Ireland, bearing date at Westminster, the
Third day of February, in the fifty-eighth year of His reign, give and
grant unto me, the said Matthew Cotes Wyatt, my exors, admors, and
assigns, His special licence, full power, sole privilege and authority,
that I, the said Matthew Cotes Wyatt, my exors, adiiors, and assigns,
should and lawfully might, during the term of years therein mentioned,
make, use, exercise, and vend, within England, Wales, and the Town
of Berwick upon Tweed, and also in all This Majesty's Colonies and Plan-
tations abroad, "THE SAFEGUARD TO PREVENT THE ACCIDENTAL MOVEMENT
OF THE COCK OF A GUN OR PISTOL OR OTHER FIRE-ARM FORWARD TOWARDS
THE HAMMER," for which the said Letters Patent are granted; and in
which said Letters Patent there is contained a proviso, that if I, th esaid

page_text: Matthew Cotes Wyatt, shall not particularly describe and ascertain the
nature of the said safeguard, 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 six calender 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, deter-
mine, and become void, as in and by the same, relation being thereunto
ad, may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the
said Matthew Cotes Wyatt, do hereby declare that the nature of the
said safeguard, and the manner in which the same is to be performed,
are particularly described and ascertained, reference being had for fur-
ther elucidation to the Drawings hereunto annexed, and the following
lescription thereof (that is to say):
That the said improved safeguard doth consist in an additional or
second sear catch or other fastening, acting either internally or ex-
ternally (but I prefer externally) against the tambler, to prevent the
forward motion of the cock, except when the trigger be pulled. And
the said improved safeguard doth morcover consist in an internal or
external (but I prefer an internal) bolt, catch, or other fastening for
the trigger, by which they are restrained from moving unless the said
bolt, catch, or other fastening be moved by a pressure on a second
guard or other external contrivance, at that part of the stock where the
hand usually grasps the gun, pistol, or other fire-arm in the act of dis-
charging it. The before mentioned improvements may be effected by
variously shaped contrivances, but these herein-after described with
reference to the Drawing are such as experience has led me to prefer.
And a second sear moved by the trigger, together with the before
mentioned external contrivance, communicating with a bolt or other
fastenings for the triggers at that part of the stock where the hand
usually grasps the gun, pistol, or other fire-arm in the act of dis-
charging it, being entirely new in the Kingdoms, and never having
being practised before herein, I am desirous to maintain this my
exclusive right and privilege to the same.

Fig 1, represents the common guard and triggers of a double gun;
u, d, a stop or bolt of metal or other substance, the point of which a,
enter a knotch cut in the triggers at k, thereby preventing the trigger
from rising till the point of the bolt a, is depressed by raising the
opposite end of the bolt a. The bolt a, a, tarns on the screw pivot c, in
the upright b; at g, is a spring fastened to the guard by a screw at h.
This spring acts against the end a, of the bolt a, a, depressing that end
and thereby forcing the end a, into the notch at K. A, is the second
guard, the end of f, of which passes up through the metal plates O, R,
till it comes in contact with the end a, of the bolt a, a. The end f, of
the second guard is furnished with a projection at e, which retains it
in its proper place.
Fig. 2, represents an inside view of the lock, with the tail of the
second scar c, e, which is held to its place between the lock plate and
the bridle by a part of the said second sear (as will herein-after be
described in Fig. 3.) passing through it, and forming a pivot for it to
turn upon. a represents the end of this said pivot; b, is a small screw.
the point of which enters a little way into one of the squares hereafter
described, to keep it to its proper place; d, is a spring, one end of
which passes round the leg of the bridle, and is kept from turning
round проп it by a small projection, which, when it is put over the leg
of the bridle, enters into the lock plate. The other end of the spring
passes under a lip or projection on the tail of the second sear, hereafter
described in Fig. 4, acting upwards to keep the second scar to its
place.
Fig. 3, represents an outside view of the lock, with the second sear
, acting in a knotch or against a projection on the tumbler c.
Fig. 4, represents an enlarged view of the tail of the second sear; a,
being the lip or projection under which the end of the spring d, Fig. 2,
acts, as before described. c, the end of the tail of the second scar,
which, when the lock is put together, lies on a parallel with the tail of
the first sear, so that they may both he moved at the same time by the
upper edge of the same trigger when pulled; e, is the screw described
