We THOMAS CANBY CHAPPELL, Lawyer, and EVERETT DAZETTA MOORE Gentle-
man of Baltimore City, State of Maryland, United States of America, 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 relates to Improvements in hermetic mouth pieces and the combina-
tion thereof with mail bags. The bag is preferably water-proof; and is preferably
made buoyant.
Fig. 1. is a view in perspective of the bag inverted.
Fig. 2. is a sectional inverted view showing interior of bag.
Fig. 3. is a perspective view of the plate or cylinder to which the bags are
fastened.
Fig. 4. is a perspective view of the removable head or cover and
Fig. 5. sectional elevation showing removable head secured to the plate to which
are fastened the canvas and water-proof bags.
Similar letters refer to similar parts throughout the several views.
The bag or pouch may consist of two parts an exterior part A and an interior
part B the mouths of which lap each other and are secured by rivets or screws to
the plate C, Figs. 1, 2 & 5. The exterior part A is made of some pliable material as
canvas, duck or hide and is preferably provided with annular chainbers A A¹ which
are filled with cork, preferably ground cork or some such buoyant substance for the
purpose of floating the bag.
A handle or grip A' may be secured to the bottom to facilitate its handling. The
interior part B is made of some waterproof material, such as oilcloth or rubber or
water-proofed canvas, and forms the receptacle for the matter to be carried. The
mouths or ends of the bags A and B are clamped to the plate C by the ring D which
is securely held by rivets or screws as shown, making an air and waterproof joint.
The removable head consists of the plate E, to which are firmly secured the

page_text: carriers E which hold the rollers e; one or several thicknesses of some waterproof
material F, and one or several thicknesses of canvas or duck G may be stratched over
this plate and clamped securely by means of the ring E2 which is rivetted or
screwed on as shown.
A chain H, couples the removable head to the plate C; this plate has openings (
which admit the carriers E of the removable head to enter and brings the rollers e in
contact with camridges C2, Figs. 2, 3, and 5.
By now turning the removable head in the right direction it is firmly pressed to
the plate C, by means of the rollers e; ascending the camridges C2, gasket K, Fig. 5,
which may be fastened to the removable head or the plate or just placed between,
may serve to make the joint more perfectly air and water proof. Staples, S S¹ are
provided on the plate Cand removable head E for the purpose of attaching a lock.
The outer or protecting bag may be dispensed with, and the chambers attached to
or constructed in the waterproof bag, or the chambers may be entirely dispensed
with, so that the bag will consist merely of a waterproof bag and its hermetically
sealed mouth piece.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed' we declare that what we
claim is :-
1st In a hermetic mouth piece for mail bags, the combination of a metallic ring
to which the bag is secured, the lower edge of which is cut into two or more inclined
planes and a cover of about the same size and shape as the ring and arranged to rest
upon it and provided on the side next the ring with two or more hooks, set rigidly
into the cover, and adapted to engage the inclined planes of the ring whereby the
cover and the ring are pressed closely together when the cover is turned, substantially
as described.
2nd-In an Hermetic Mouth Piece for mail bags, the combination of a metallic
ring to which the bag is secured, the lower edge of which is cut into two or more
inclined planes, and a cover of about the same size and shape as the ring, and arranged
to rest upon it, and provided on the side next the ring with two or more hooks or
carriers set rigidly into the cover and provided with friction rollers attached to them
and engaging the inclined planes of the ring, whereby the cover is turned substantially
as described.
3: In an Hermetic Mouth Piece for mail bags, the combination of a metallic
ring to which the mail bag is secured the lower edge of which is provided with a
downwardly projecting flange cut into two or more inclined planes, a cover of about
the same size and shape as the ring and provided on the side next the ring with two
or more hooks set rigidly into the cover and adapted to engage the inclined planes of
the flange and a gasket interposed between the ring and cover as and for the purpose
specified.
4: In an Hermetic Mouth Piece for mail bags, the combination of a metallic
ring to which the bag is secured, cut with slots or ways, to permit the hooks or
carriers to pass through it, the lower edge of said ring being cut into two or more
inclined planes and a cover of about the same size and shape as the ring and arranged
to rest upon it and provided on the side next the ring with two or more hooks set
rigidly into the cover and adapted to engage the inclined planes of the ring, whereby
the cover and ring are pressed closely together when the cover is turned, substantially
as described.
5: In an Hermetic Mouth Piece for mail bags, the combination of a metallic ring
to which the bag is secured, the lower edge of which is cut into two or more inclined
planes and a cover of about the same size and shape as the ring and constructed of
two rings of metal between which is rivetted a sheet of flexible water-proof material
and arranged to rest upon the bag ring and provided on the side next to the bag ring
with two or more hooks set rigidly into the rim of the cover and adapted to engage
the inclined planes of the ring, whereby the cover and the ring are pressed closely
together when the cover is turned substantially as described.

page_text: 6-In an Hermetic Mouth Piece for mail bags, the combination of a metallic ring
counter-sunk on the inner edge and provided with a gasket resting in said counter-
sunk space, and having a downwardly projecting flange the lower edge of which is
cut into two or more inclined planes, and a cover of such a size and shape as to fit the
counter-sunk space in the ring and rest upon the gasket and having hooks provided
with rollers secured to the sides of the cover next the ring and adapted to engage the
inclined planes of the flange, whereby the cover and the gasket will be pressed closely
together when the cover is turned substantially as described.
7:-The combination of an Hermetic Mouth Piece consisting of a metallic ring
provided on its lower side with inclined planes, a cover provided on the side next the
ring with means adapted to engage the inclined planes and press the ring and cover
together when the cover is turned, and a water-proof mail bag secured to the ring
whereby the bag may be sealed so as to be water tight.
