Improvements in Machinery for use in the Manufacture of Casks or
Barrels.
I, ANTHON BERNHARD ELIAS NILSEN, of Fredriksstad, in the Kingdom of Norway,
Manufacturer, 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 machinery for shaping the staves of casks or barrels, and
the invention consists mainly in the employment of a rotating concave disc in com-
bination with an obliquely, vertically and horizontally adjustable guide whereby the
edges of the staves are simultaneously bevelled and curved so that when the staves are
bellied or curved and united to form a cask or barrel, the latter will have the required
ellipsoidal shape.
To enable my invention to be fully understood I will describe how it can be carried
into practice by reference to the accompanying drawings, in which―
Figure 1 is an elevation of a machine for bevelling, and curving the edges of
the staves of casks or barrels constructed according to my invention, the concave disc
being shewn in section ;
Figure 2 is a plan;
Figure 3 is a back view; and
Figure 4 is a front view of the same.
a is the frame of the machine on which a shaft c rotates in the journals 61, 62,
which shaft by means of a belt-pulley d is operated by the motor and carries the disc e
keyed upon its free end. One side of the disc e is concave and provided with a
number of knives or plane-irons which are adjustable by means of screws fl and
are so arranged that their edges extend slightly beyond the concave surface of the
disc.
Close to the disc is placed a supporting frame g secured upon the base-plate of the
frame a, the position of which frame g can be adjusted horizontally by means of
screws and nuts h. Upon the upper part of the frame g are fixed channelled bars i to
which the guide k is pivotted at a a. The bars i are vertically adjustable by means
of screws and nuts and the guide k, can, by means of screws and nuts m on the
bars i and slots in the guide k, be brought into a more or less oblique position in
order to give to the edge of the stave the necessary bevel to suit the diameter of the
cask.
The stave is forced by hand into an opening in the frame k, which opening
through the medium of guiding blocks n, n provided with grooves and adjusting
screws can be varied in length according to the length of the staves.
By reason of the concave face of the disc e in which the plane-irons fare fixed the
edge of the stave will become curved, and it will at the same time, by reason of the
angular position of the adjustable guide k, be more or less bevelled, the angle to which
the guide k is to be adjusted depending on the bevel to be given to the stave or, in
other words, on the diameter to be given to the cask.
It is then only necessary to bend, curve or belly the staves in any suitable manner
after which they will be ready to be joined together to form the cask.
In order to prevent accidents, if the plane-irons should get loose during the
working of the machine, the disc may be enclosed in a casing, not shewn in the
drawings.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
:-
1. In a machine for bevelling and curving the edges of staves for casks and

page_text: barrels, a concave disc e provided with plane-irons f, the disc having a guide k
adjustable vertically as well as horizontally, substantially as shown and for the purpose
specified.
2. In a machine for bevelling and curving the edges of staves for casks or
barrels, a guide k pivoted so as to be obliquely adjustable, in order to allow of
giving to the edge of the stave the necessary bevel to suit the diameter of the
cask or barrel, substantially as hereinbefore described and illustrated in the accom-
panying drawings.
3. In a machine for bevelling and curving the edges of staves for casks or barrels,
a guide k provided with guiding-blocks n, n in order to allow of varying the length
of the guide-opening k³, substantially as herein before described and illustrated in the
accompanying drawings.
