I, ROBERT HUDSON, of Gildersome near Leeds, in the County of York, Engineer
and Ironfounder, do hereby declare the nature of said invention for "AN IMPROVED
MOUTHPIECE AND LID SUITABLE FOR POWDER MAGAZINES, METALLIC BARRELS OR
CYLINDERS, BOXES AND THE LIKE AND MEANS FOR READILY OPENING AND
CLOSING THE SAME to be as follows:-
"
This invention has reference to an improved mouthpiece and lid suitable for
powder magazines, metallic barrels or cylinders, boxes, and the like, and means for
readily opening and closing the same, the object being when the lid requires to be
frequently opened and closed that none of the component parts which form the
lid and its fastenings shall become detached and lost. In order to effect this
I construct the mouthpiece of annular form, which I attach to and around the
opening of a magazine, barrel or cylinder, box and the like, such as above referred
to, by rivets or otherwise, I form around the periphery of said mouthpiece a
number of recesses of T form for the reception of a corresponding number of
T headed bolts, the T parts of which are made circular in cross-section so that
when access is required to a magazine, barrel or cylinder, box and the like, the
nuts of the T headed bolts are slackened or slightly unturned, (the bolt holes in
the lid being open towards its periphery) the bolts are capable of turning freely in
an outward direction in the above named T, recesses in the periphery of the mouth-
piece (or equivalent means may be provided for enabling the bolts to be turned)
and when so turned that their axes are radial to the centre of such mouthpiece the
lid may be opened.
The nuts of said bolts may be prevented from being turned off by any well
known means such as rivetting over the ends of the bolts or by crosspinning.
At one part of the mouthpiece I provide a double bolt in the form of what is
known as a "square staple," and I make a special recess in the periphery of the
mouthpiece for its reception, its general cross-section is circular, in order that it
may turn in its recess in the same manner as the T headed bolts previously
referred to. This double bolt and its recess form a hinge for the lid when being

page_text: opened or closed and is provided with nuts for finally tightening the lid when
closed.
The holes in the lid for receiving this double bolt are not open to the periphery
thereof as in the holes for the single bolts.
In order to prevent the T headed bolts and the double bolt from leaving their
respective recesses I surround the aforesaid mouthpiece with a metallic hoop which
covers the head parts of the T, recesses, parts of this hoop being cut away to
allow the "single" bolts to be turned to the radial position previously referred to
without leaving their recesses. When it is required to gain access to a magazine,
barrel or cylinder, box or the like, the nuts on the single bolts are slackened the
bolts turned back into the radial position before described when the lid is free to
be opened. On the lid being closed the bolts are turned to their former position
and the nuts tightened, when the lid becomes securely fixed.

I, ROBERT HUDSON of Gildersome, near Leeds, in the County of York, Engineer
and Ironfounder, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention has reference to an improved mouthpiece and lid suitable for
powder magazines, metallic barrels or cylinders, boxes and the like, and means for
readily opening and closing the same, the object being to enable the lid to be
frequently opened and closed without liability of the parts comprising the lid and
its fastenings becoming detached from the mouthpiece and lost-To this end
I construct the mouthpiece of annular form and attach it to and around the
opening of the magazine or other vessel such as above referred to, by rivets or
otherwise.
I form around the periphery of the said mouthpiece, a groove which with
openings at right angles thereto, form recesses for a number of T headed bolts,
the T heads of which are made circular in cross-section so that when access is
required to the magazine or vessel the nuts of the T headed bolts are slackened or
alightly turned, the bolts can then be turned upon their heads as hinges so that
the bolts will leave the bolt holes in the lid which for this purpose are open at
the periphery. The bolts are turned in an outward direction (or equivalent means
may be provided for enabling the bolts to be so turned) until their axes are radial
to the centre of the mouthpiece, when the lid may be opened. The nuts may
be prevented from leaving the bolta by any well known means, such as rivetting
over the ends of the bolts or by cross-pinning. At one part of the mouthpiece
I provide a double bolt in the form of what is known as a
square staple" and
I make a special recess in the periphery of the mouthpiece for its reception; its
general cross section is circular, in order that it may turn in its recess in the same
manner as the T, headed bolts can turn in their recesses. This double bolt and
its recess in the mouthpiece form a hinge for the lid on its being opened and
closed, and the bolt is provided with nuts for permanently connecting it to the
lid and for assisting to tighten down the same on against the mouthpiece when
closed.
"
The holes in the lid for receiving this double bolt are not open to the periphery
thereof as in the case of the holes for the T headed bolts. In order to prevent
the T headed bolts and also the double bolt from leaving their respective recesses
I surround the aforesaid mouthpiece with a metallic hoop covering up the recess,
portions of this hoop being cut away to allow the single or T bolts to be turned to
the radial position previously referred to without leaving the recesses; portions
are also cut away for the double bolt so that it may turn in its recess when the lid
is opened or closed. When it is required to obtain access to the magazine or
vessel, the nuts on the T bolts are slackened, the bolts turned backward into the

page_text: radial position beforementioned and then the lid is free to be opened. On the lid
being closed the bolts are turned to their former position the nuts are tightened
and the lid is thus securely fixed.
In the accompanying drawings
Fig. 1. is an elevation, and Fig. 2, is a plan of a mouthpiece according to my
invention, the half A, of the plan shews the T bolts turned backwards into a
position radial to the mouthpiece and the lid open, the other half B, shews the lid
closed. Fig. 3, is a section on the line C, C, also showing the lid open. -D, is a
part of a magazine, metallic barrel or cylinder, box or the like, to which such a
mouthpiece is applicable, E, is the mouthpiece secured thereto by the rivets F,-
G, is the lid, H, H, H, are T beaded bolts for securing the same to the mouthpiece.
H 1, is the double or staple bolt (shewn in elevation in Fig. 4) which forms the
hinge joint upon which the lid turns when being opened.
The bolt holes H 2, in the lid are open to the outer edge or periphery thereof to
allow the bolts H, when their nuts are slackened, to be turned backward as and
for the purpose above referred to, the T heads thereof being cylindrical to permit
of such turning in their respective recesses, I, is a metallic boop surrounding
the mouthpiece and fixed thereto by the screws J, and prevents the bolts from
leaving their respective recesses; K, is a part fixed within the said hoop for
backing up the middle portion of the double or staple bolt H 1.
The hoop I, is notched to allow both the T bolts and the staple bolt to be
turned downward as shewn in Figs. 1 and 2.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is:-
:
1. Means for opening and securely fastening the lids of powder magazines of
other vessels comprising T headed bolts and nuts arranged in such wise that the
opening, closing and fastening of the lid can be effected without the necessity of
removing the nuts from the bolts or the bolts from the mouthpiece, thus avoiding the
risk of the bolts and nuts getting lost, also saving time and trouble occasioned by
taking out and replacing the bolts and nuts as is ordinarily necessary when access
to a magazine or vessel is required.
2. Securing T headed bolts such as referred to in the preceding claim within
recesses in the mouthpiece, so that the bolts may be turned upon the said
T heads within such recesses, by means of a hoop such as I, as described above
with reference to the drawings.
3. The application and use of the double or staple bolt arranged to serve as a
hinge for the lid and also as a means of tightening the lid when closed against the
mouthpiece as described above and shewn in the drawings.
4. The combination of parts constituting the improved mouthpiece and lid with
fastenings suitable for powder magazines, metallic barrels or cylinders arranged
and operating as hereinabove described with reference to and shewn in the
drawings annexed.
