Year: 1833

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
CHARLES JONES, of Birmingham, in the County of Warwick, Gun
Maker, send greeting.
WHEREAS His present most Excellent Majesty King William the
Fourth, by His Letters Patent under the Great Seal of Great Britain,
bearing date at Westminster, the Seventh day of March, in the third
year of His reign, did, for Himself, His heirs and successors, give and
grant unto me, the said Charles Jones, His especial licence, full
power, sole privilege and authority, that I, the said Charles Jones, my
exors, adñiors, and assigns, or such others as I, the said Charles Jones,
iny exors, adors, or assigns, should at any time agree with, and no
others, from time to time and at all times during the term of years
therein expressed, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick upon Tweed,
the Invention of "CERTAIN IMPROVEMENTS UPON THE PERCUSSION LOCKS OF
FIRE-ARMS," communicated in part by a foreigner residing abroad"; in
which said Letters Patent is contained a proviso, that I, the said
Charles Jones, shall cause a particular description of the nature of the
said Invention, and in what manner the same is to be performed, to be

page_text: inrolled in His said Majesty's High Court of Chancery within six
calendar months next and immediately after the date of the said in part
recited Letters Patent, as in and by the same, reference being there-
unto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, 1, the
said Charles Jones, do hereby declare that the said Invention of cer-
tain improvements upon the percussion locks of fire arms for which I
claim the exclusive privilege, and the manner in which the same are to
be carried into effect, are particularly set forth and explained in the
following description thereof, reference being had to the Drawings
hereunto annexed, and to the letters and figures marked thereon (that
is to say):
The said improvements consists,-firstly, in combining the parts
corresponding to the tumbler, the cock or hammer, and the trigger, in
one piece.
Secondly, in bringing the action of the main spring upon the part
corresponding to the tumbler in such a manner as to become a detent
when the piece is cocked, and a motive accelerating force in the action
of discharging, and by this arrangement to render the sear, the sear
spring, and all other springs appertaining to the lock unnecessary.
Thirdly, in placing the whole of the lock or locks, except the trigger
or triggers, within the stock of the piece, and in covering the works
from rain or other external injury by a sliding shutter, which is drawn
back when the priming cap is to be put on the nipple.
And fourthly, for double guns, in affixing both locks to one lock
plate; and I do further declare that the manner in which I carry the
said improvements into effect is described by the Drawings hereunto
annexed, as explained by the following references.
Fig. 1, represents a side view of the lock after having been dis-
charged, with parts of the barrel and stock, the side of the stock next
the eye being removed.

fulcrum pieces, between which the hammer piece is supported and
urns on an axle; c, the axle; d, the main spring, with a notch at c, to
assist in detaining the hammer piece at cock; e, the detent notch; f,
an antrifriction roller affixed to the tumbler part of the hammer piece,
to run along the spring and rest in the detent notch; g, the sliding
shutter; h, a spring acting by friction in a groove on the underside o
the shutter, to hold it in the position in which it is placed; k, the
groove in the shutter; 7, the shutter frame; m, a shelf to skreen the
works.

CHARLES (...) JONES.

page_text: En the Matter of a Patent granted to Charles-Jones, of
Birmingham, in the County of Warwick, Gunmaker, for,
"A NEW ARRANGEMENT OF ADDITIONS TO AND ALTERATIONS IN
CERTAIN PARTS OF GUN AND PISTOL LOCKS," bearing date at-
Westminster, the Twelfth day of June, One thousand eight,
DISCLAIMERS AND MEMORANDUMS OF ALTERATIONS entered
by the said Charles Jones with the Clerks of the Patents of
England, pursuant to an Act passed in the fifth and sixth years of'
'His present Majesty, entitled "An Act to amend the Law touch-
ing Letters Patent for Inventions."
I, the said, CHARLES JONES, hereby declare, that I have very lately
discovered that the "áttaching of the main spring, tumbler, sear, and
bridle to a centre rise or block formed on the trigger plate for that
purpose," is not new, though I believed it was so when I enrolled. my
Specification of my Invention; for which reason I hereby disclaim. that
part of the Specification of the said Patent..

page_text: And further, I, the said Charles Jones, do hereby declare, that
causing the trigger and sear to act with one common spring," is not
a useful arrangement, for which reason I hereby further disclaim that
part also of the said Specification.
And further, I, the said Charles Jones, do hereby declare, that for
the reasons aforesaid, I hereby further disclaim that part of the said
Specification comprised under the third head of Invention, and which
is in the words following, that is to say, "no separate trigger spring,
and making the centre rise before mentioned on the trigger plate
serve the office of the ordinary lock plate."
And further, I, the said Charles Jones, do hereby declare, that for
the reasons aforesaid, I do hereby further disclaim that part of the said
Specification comprised in what is called the claiming clause, and
which consists of the following words, that is to say, "The centre rise
B, on the trigger plate, and attaching the various parts of the lock
thereto."
And further, I, the said Charles Jones, do hereby make the following
alteration in the said Specification, that is to say, I omit the word "by"
in the said claiming clause, for this reason, namely, the same having
been apparently inserted by mistake, inasmuch as the sense requires
such alteration.
And further, I, the said Charles Jones, do hereby inake the fol-
lowing alteration in the title of my said Invention, for this reason,
namely, in order to make the same consistent with what my said
Specification will describe my, said Invention to be when such dis-
claimers as aforesaid shall have been entered as aforesaid, (that is to
say), I hereby substitute the words "an alteration" for the word
"alterations" in the said title.
In witness whereof, I have hereunto set my hand, this Twenty-
first day of September, One thousand eight hundred and
CHARLES JONES.
