page_text: Improvements in or relating to Barrels and like Vessels.
I, THOMAS LARKIN, Chemical Works' Manager, of Simouside Villa, East
Jarrow, in the County of Durham, do hereby declare the nature of this invention
to be as follows:-
My invention relates to barrels and like vessels or receptacles especially those
for materials liable to explode by friction, impact or lieat.
At present, the vessels or receptacles are either constructed of wood or metal
and are closed by devices which, if not unsafe and insecure, are complicated,
inconvenient and expensive.
My invention refers to these devices with the object of obtaining safety and
security with simplicity and efficiency in use and economy in cost.
According to my invention, I apply at the mouth or one end of the vessel a
lid or cover which may be adapted to fit over, or into, the end of the vessel; in
the latter case, a ledge is provided within the vessel to constitute a seat for the
lid.
Between the meeting faces of the lid and vessel I interpose a packing, sucli
as a ring of india rubber or other suitable material, for ensuring tightness at
the joint.
•
Within the vessel I arrange a bolt or rod of such a length as to extend the
length of the vessel and project beyond its mouth. This bolt or rod may con-
veniently be connected to the closed end of the vessel.
The lid or cover is made with a hole to permit the passage of the bolt or rod
when the lid is fitted' on its seat on which it is fastened by appropriate devices
applied at the end of the bolt or rod, such as a nut (the end of the bolt or rod
being screwed) or by a pin or wedge driven through a corresponding hole in the
bolt or rod.
Thus it will be seen that in addition to efficiency and economy accruing the
opening and closing of the vessel are rendered easy and safe to accomplish,
whilst, when the parts are in the normal position, the vessel is effectually stayed
at the ends by the bolt or rod.
I have specially devised my invention for metal vessels, but of course it is
equally applicable to those of wood.

page_text: I, THOMAS LARKIN, Chemical Works' Manager, of Simonside Villa, East
Jarrow, in the County of Durham, 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:-
My invention relates to barrels and like vessels or receptacles, especially those
for materials liable to explode by friction, impact or heat.
At present, the vessels or receptacles are either constructed of wood or metal
and are closed by devices which, if not unsafe and insecure, are complicated,
inconvenient and expensive.
My invention refers to these devices with the object of obtaining safety and
security with simplicity and efficiency in use and economy in cost..
I have specially devised my invention for metal vessels, but, of course, it is
equally applicable to those of wood, and in the accompanying drawings, to which
I will refer in the following description of it, I illustrate its application to both
types, Figs. 1 and 2 being respectively a central vertical section and a plan of a
metal vessel embodying the improvements, and Figs. 3 and 4 similar views of a
wood vessel.
According to my invention, I apply at the mouth or one end of the vessel A
a lid or cover B which is best constructed of the same material as the vessel in
any appropriate way, and which may be adapted to fit over the end of the vessel;
or into it, as represented in the drawings, in which case a ledge a is provided
and secured within the vessel to constitute a seat for the lid, the ledge being
suitably formed by an angle iron in a metal-vessel, or by a wood ring in a wooden
one,
For conveniently handling the lid or cover, it may be provided with handles,
as indicated at b, b.
Between the meeting faces of the lid B and vessel A I interpose a packing C,
such as a ring of india rubber, asbestos or other suitable material, for ensuring
tightness at the joint. Though preferable, this packing, of course, is not
absolutely necessary.
Within the vessel A I arrange a metal bolt or rod D of such a length as to
extend the length of the vessel and project beyond its mouth: This bolt or rod
is conveniently connected to the closed end of the vessel, as by a nut and washer
as shown at d, Figs. 1 and 3.
The lid or cover Bis made with a hole to permit the passage of the bolt or
rod ) when the lid is fitted on its seat on which it is fastened by appropriate
devices applied at the end of the bolt or rod; such as a nut (the end of the bolt
or rod being screwed) as shown at d, or by a pin or wedge driven through a
corresponding hole in the bolt or rod. As illustrated, I prefer to sink this con-
nection into the lid or cover when of wood.
Thus it will be seen that in addition to efficiency and economy accruing, the
opening and closing of the vessel are rendered easy and safe to accomplish,
whilst, when the parts are in the normal position, the vessel is effectually stayed
at the ends by the bolt or rod.
I have described the use of one bolt or rod, as I find this generally sufficient,
but, as will be obvious, when circumstances necessitate, two or more rods or
bolts may be adopted, they being applied in the way explained.

Having now particularly described and ascertained the nature of
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. Closing barrels and like vessels, substantially as described and shown in
the accompanying drawings.
2. For closing barrels and like vessels, the combination with the lid or cover,
of a bolt or rod (or bolts or rods) connected to the closed end of the vessel and
extending the length of same and through the lid or cover, and a fastening
device, such as a nut, or a pin or a wedge, applied at the free end of the bolt or
rod (or bolts or rods) for securing the lid or cover on its seat, substantially as
described!
3. A barrel or like vessel furnislied with a closing device, substantially as
described in reference to the accompanying drawings.
