9 Claims.
The general object of vmy invention is to pro
vide an improved closure for barrels,- casks and
similar receptacles. More specifically, the ob-r
ject ‘of my invention is to provide a simple re
liable and‘eiîective closure for barrels. which may
be made either of wood or of iron, and which is
especially adapted to withstand a high internal
pressure.
y
.
I A further object of my invention is to provide
a barrel or other receptacle with tight joints even
at a high internal pressure.
'
Another object of my invention is to provide
a closure with interchangeable parts which are
easily removable and when once removed may
readily be replaced on the cylinder and fixed
thereto without damaging any parts of the barrel.
` A still further object of my invention is` to pro
vide a closure for barrels and like containers
which shows the above mentioned properties and
which all the same allows the barrel to be easily
handled by hand Vor lifted with a crane. »The
barrel according to my invention shows a re
markable stability.

These and other objects are attained by provid
ing ties, either tie rods or tie bands co-operating’

known advantages of wooden barrels with those
of steel barrels or casks.
I
The various features of novelty which char->
acterize my invention Vare pointed out with par
ticularity in the claims annexed to and forming
a part of this specification; but for a better un
derstanding oi the invention, however, its advan
tages and specific objects attained with its use,
reference should be had to the accompanying
drawing and descriptive matter in which I have
illustrated and described preferred embodiments
of my invention.
Of the drawing:-

In the drawing similar references have been
used to designate similar parts. In all modiñca

on the cover, 4' the bottom or lower pressure
with pressure rings which press the heads onto
the ends of the cylinder or drum in` such a Way
that the packing, which is preferably a rubber
packing, is subjected to a pressure suiiicient to
close the joint but not exceeding a certain pre
I
According to my invention the packing is ar
ranged in grooves or recesses protruding there
‘ ‘ from for a certain .amount only suñicient to pack
the joint tightly by its inherent elasticity when
the lid is pressed on the face of the cylinder. It
is important that the packing according to my
invention has not to stand the entire pressure
4,0 with which the heads of the barrel are pressed on
the cylinder and that its elasticity is not im
paired thereby. The packing compensates for
possible inaccuracies either of the cylinder or of
the heads.
'I‘he invention may be embodied in _various
forms. In one preferred form of my invention
means are provided to allow the lid to be re
moved without removing the bottom pressure
ring. The upper pressure ring may be so con
structed as to allow the lid to be removed with
out removing the said pressure ring. Finally the
ties, especially if tie rods are used, may be ar
ranged between two concentric jackets which are
preferably made of wood. Such a barrel is
55 therefore provided with a double cylinder and
ring, 5 the ties and 6 resilient packings.
Whereas steel bands may also‘be used as `ties
itis preferable to use tie rods 5. As shown inV
Fig. 1 the rings 4 and 4’ are T-shaped, the hori
zontal web resting on the ends Z and' 3. The
latter and the cylinder I as well are made of
wood. The rings 4 and 4’ are held together by
means of rods 5 the heads 'I of which bear against
the web of the lower ring 4' while the upper
ends I4 are provided with screw threads adapted
to receive nuts I5. These nuts are provided with
a head I0 which lies partly in a recess- of the
ring 4. The vertical flanges of these rings 4 and
4’ guide the rods 5 which are thereby exactly
concentrically arranged with respect to cylinder
I. The nuts are housed well within the rings
4, 4’. This feature is of considerable importance
for the transport of the barrels eitherby rollingV 50
them or by lifting them with a crane. The rings
4 and 4' and therefore also the ends 2 and 3 of
the barrel are pressed on the cylinder I by means
of the screw nuts I5. The latter allow to vary`
the pressure as may be desired.

ing material is to be used which by its inherent
elasticity closes the joint between the ends of the
cross-section. The bars 5 are not flexible and
are adapted to press the rings 4 and 4' on the
cylinder I. The bars 5 are simply passed through
barrel and the cylinder. The cross section of the
packing ring has to be suñiciently large and the
recess in which the packing is lodged appropri
ately dimensioned to obviate a pressure on the

statutes, IY have illustrated and described the best
forms of my invention now known to me, it will
be apparent to those skilled in the art that
changes in form may be made without departing
from the spirit of my invention as set forth in
the appended claims, and some features of my
invention may sometimes be used to advantage
without a corresponding use of other features.

The barrel according to Figs. fl and 5 differs
from the above described embodiments in that
tacle having a relatively thin-wall cylinder and
35 two concentric jackets I and I8 are provided.
Both jackets are made of wood, preferably of ply
wood. As in the other embodiments above re
ferred to rings 4 and 4’ are kept together by
means of tie rods 5. The outer jacket protects
40 the tie rods 5 whereas a rolling ring I 9 allows an
easy rolling of the barrel.
This construction combines the advantages of
the known wooden barrels with those of the steel
barrels.
In all the modifications shown in the drawing
the bottom end of the container might also be
ñxedly connected to cylinder I. Y
The packing 6 shown in the Figs. 1 to 6 has
never to stand the entire pressure by which the
50 pressure rings 4 and 4’ are pulled together. This
lengthens considerably the life of such a packing.
The dimensions of the parts above referred to are
such as to impart to the packing 6 aV pressure
sufficient to ensure a tight joint but not high

The packing 6 of all the modifications shown
in the drawing lies in recesses either of the lid,
or of the bottom end 3 or of the cylinder I.
The pressure by which the'lid and the bottom
end are pressed on the faces of the cylinder is
mostly very considerable. If the pressure within
the barrel varies between 1 to 5 atmospheres the
pressure exerted on the lid will Vary between 1000
65 to 5000 kilograms by an inside diameter of 367
millimeters of the cylinder. The inside pressure
tends to lift the lid and the bottom end from
the respective faces of the cylinder. A small gap
of but 0.1 millimeter will be produced between
70 the lid, the bottom end and the cylinder. The
whole pressure of 5 atm. in the barrel will now
act on the packing and will press the latter in
the said gap ensuring thereby automatically a
most perfectly tight joint.
