IMPROVEMENTS ON CERTAIN DESCRIPTION OF FIRE-ARMS
Year: 1835

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JOSEPH EGG, of Piccadilly, in the County of Middlesex, 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 dato at Westminster, the Ninth day of May, in the fifth year
of His reign, did, for Himself, His heirs and successors, give and
grant unto me, the said Joseph Egg, His especial licence, full power,
sole privilege and authority, that I, the said Joseph Egg, ny exors,
adñiors, and assigns, or such others as I, the said Joseph Egg, my
exors, adññiors, 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,
ny Invention of "IMPROVEMENTS ON CERTAIN DESCRIPTION OF FIRE-ARMS;"
in which said Letters Patent is contained a proviso, that I, the said
Joseph Egg, shall cause a particular description of the nature of my
said Invention, and in what manner the same is to be performed, to

page_text: be 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
thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the
said Joseph Egg, do hereby declare that the nature of my said Inven-
tion, and in what manner the same is to be performed, is particularly
described and ascertained in and by the following description thereof,
reference being had to the Drawing hereunto annexed, and to the
figures and letters marked thereon, that is to say:
My improvements on fire-arms consist in applying peculiarly con-
structed priming magazines to be attached on the barrel of fowling
pieces, pistols, and such like fire-armis; and in the mode of conducting
the detonating tube or primer from the magazines to the pan, cup, or
touch-hole, for the purpose of priming the piece; and also in a mode of
cutting off the communication between the touch hole and priming
chamber or magazine at the time the piece is discharged.
DESCRIPTION OF THE DRAWING.
Figure 1, is a view of the lock and breech part of a gun upon this
improved principle, the parts standing as at half cock. Fig. 2, a view s
of the same after the piece is discharged or the cock at bearing.
Fig. 3, the inside view of the lock detached, the parts in the position
of Fig. 1. Fig. 4, is also a view of the inside of the lock detached,
the parts in the position of Fig. 2. Fig. 5, an horizontal view of a
double barrel, showing the recess between the barrels before the S
magazine is attached. Fig. 7, the magazine detached, and which
consists of two tubes, when for a double barrel of any length preferred,
fastened to a top piece, and which for this construction of lock must be
filled with short tubes containing detonating composition, and then
deposited in the recess a, and there secured by a screw or other 8
suitable contrivance. On raising the muzzle of the piece the priming
descends to the broad part of the chamber b, and there passes through
a small passage or passages c, c, in a lateral direction. The outer part
of this passage is closed by a slide or conductor, shewn at Figures

page_text: 3 and 4; but when; the cock is raised, aspat Fig1, an aperture z,
comes opposite this; passage c; and permits the priming to descend
through it to the slide or conductor, and which empty's! itself! into the
pan or touch-holo e. The head of the slide or, conductor: has a small
protuberance, as. shewn at Figures 1 and:8, which serves as a cap: or
cover to the pan or touch-hole; and which passes the imagazine.cas
shewn at Fig. 1; and the pulling the trigger, the tumbler brings down
the lever which, by its connection with the arm of the slide or
conductor d, seen at Figures 3 and 4, covers the communication, as at
Figure 3, to the position of Fig. 4, and by that means cuts off the
communication between the priming chamber and the cup or touch-
hole.

It will be evident from the above... description, that a similar
priming magazine may be applied to fire-arms intended to be primed
with gunpowder, but in that case it will be necessary to enlarge the
passage leading from the chamber to the pan or touch-hole, and a
different constructed lock must be employed, with a flint cock and
hammer. I do not, however, claim any novelty in the lock or any
other part of the piece, except in those parts which are marked with
letters upon the Drawing referred to as above. In short, my im-
provements in the construction of guns and fire-arms upon the self-
priming and detonating principle are confined to the construction of a
priming chamber or magazine attached to the barrel or barrels of fire-
arms as above described, though the same may be varied to suit other
forms, place, or position contiguous to the breech, false breech, or
barrel, and in the necessary shield, slide, or guide or conductor, which
also may be varied in shape or position for the purpose of admitting
the priming to the touch-hole when the piece is loaded, and of cutting
off the communication between the chamber and the touch-hole when
the piece is discharging.
In witness whereof, I, the said Joseph Egg, have hereunto set
my hand and seal, this Ninth day of November, in the year of
JOSEPH (L.S.) EGG.
