Improved Hoops or Bands for Casks and like Artioles.
A communication by ERNST MAACK, of Bockholt, and FRIEDRICH LOHFF, of
16^, Schwartauer Allee, Lübeck, both in the Empire of Germany.
1, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6, Bank Street,
Manchester both in the County of Lancaster and 323 High Holborn in the
County of Middlesex, Civil Engineer, 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 :-
In the manufacture of casks for vinegar, wine and the like, it is preferable to
employ adjustable bands or hoops consisting of various segments of a circle. The
iron hoops hitherto employed have the double disadvantage that, firstly, they
oxidise very easily, and, secondly, if two staves on the side opposite to the point of
division are not tightly closed, a subsequent tightening of the hoop is of little use.
This invention has for its object a band or hoop which is intended to remove the
above named drawback.
It is shown on the accompanying drawing,
Figure 1 being a part of a removable or adjustable hoop or band at the point of
connection;
Figure 2 a view of a band or hoop composed of four parts;
Figure 3 is a section of the latter.
The band or hoop which may be conically shaped to suit the outer form of the
cask, is composed of several segments of a circle a a' a', etcetera, which, in order to
prevent oxidation, are made of wood (preferably ash wood). At each end of these
bands a metallic angle piece c is fastened by means of screws or rivets. These
pieces, as well as the screws or rivets d, are made of a non-oxidising metal, or are
coated with such. Screw-bolts e are passed through the lugs c' of two adjacent
angle pieces which lugs are bent outwards at right angles, and the bands or hoops
are drawn tight by means of these bolts.
The number of segment pieces employed, which may be of similar size & shape
so as to be interchangeable is regulated by the circumference of the cask, but it is
preferable to keep the separate parts as small as possible in order to obtain as
many sided a polygon as possible, which, when placed round the cask receives a
circular form by tightening the screw bolts e. By employing as many segments as
possible, it is also possible to remedy as rapidly and surely as possible places which
are not tight, because the connecting screw bolt e which is nearest to the untight
place can always be tightened up. A pressing together or tightening of the staves
may thus be obtained at the actual point where they are untight which is of great
importance particularly in the case of large storage casks. By employing as many
segments as possible, any which may have become defective may be easily replaced
by others. No rusting or perishing of the hoop can any longer take place, as the
material of the segments which come in contact with the outside of the cask is the
same as that of the cask.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is-
An improved adjustable wooden boop or band for casks of all kinds, consisting of
any suitable number of interchangeable wooden segment pieces which are drawn

page_text: and held together by means of non-oxidising metallic angle pieces and bolts,
substantially as and for the purpose described and shown.
