page_text: I, EVERHARDUS THEODORUS JACOBUS WILHELMUS KREPEL, of Klarenbeek, in
the Kingdom of Holland, Manufacturer and Land Owner, do hereby declare the
nature of this invention to be as follows:-
-
My invention relates to a valuable improvement in the manufacture of wooden
barrels or vessels of any description.
It is well known that wooden vessels are usually manufactured by forming the
walls thereof of several pieces or staves which may have curved edges and are of
the same height as the vessels and are kept in contact by iron or wooden hoops.
The edges of the staves must be worked accurately so as to butt perfectly. There
are as many joints as there are staves and as these must be kept tight, a large
number of hoops must be used to keep the staves together.
My invention has for its object a cheaper, simpler and more rapid process of
manufacturing wooden barrels, tubs, pails and the like, from one single plank of
wood, whereby the barrel has only one joint and requires but few hoops to keep it
tight. It is also much easier to fit bottoms in barrels made in one piece according
to my process, than to provide the staves with grooves in which said bottoms enter.
In order to manufacture wooden vessels with walls made of one single piece, I
proceed as follows:-
By means of a veneering machine which need not be of a special construction
or type, but large and strong enough for the purpose in view, I cut out of round
timbers which have been steamed, planks having the thickness of the wall of the
receptacle to be manufactured. This thickness can vary from the thinnest veneer
to / of an inch and more if necessary.
The length of the plank depends of course upon the width of the machine and
planks of the required length can be at once obtained by cutting the tree trunk
into blocks having the length of the vessel to be manufactured.
The forming of these planks into vessels of varied shape and form is very
simple.
After they have been dried by suitable means, the planks are bent to a circular
shape and have their two edges brought together. In order to manufacture a
conical vessel, the flat rectangular plank is cut so as to form a trapezoid and
then bent so as to bring its butting edges together.
One of the parallel sides of the trapezoid may be provided with saw cuts. If
both ends of the plank are provided with saw cuts, a barrel of convex or bellied
shape will be formed by bringing the butting edges together.
Any other form of vessel can easily be made out of flat planks.
As material for the new vessels I use preferably soft woods, such as poplar, alder,
aspen and the like.
In order to render the vessels made of these woods more suitable for the con-
veyance of butter, they are then fitted with a lining consisting of veneer of oak
or other wood which must be thin and which fats cannot penetrate or at least

page_text: with difficulty. This lining should be such as not to communicate any smell
to the contents of the barrel.
It is clear that vessels made in this manner must be much cheaper than coopers'
goods made by the old process; for butter casks and other dry goods more
especially, the difference in price is enormous.

I, EVERITARDUS THEODORUS JACOBUS WILHELMUS KREPEL, of Klarenbeek, in
the Kingdom of Holland, Manufacturer and Land Owner, 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 a valuable improvement in the manufacture of wooden
barrels or vessels of any description.
It is well known that wooden vessels are usually manufactured by forming the
walls thereof of several pieces or staves which may have curved edges and are of
the same height as the vessels and are kept in contact by iron or wooden hoops.
The edges of the staves must be worked accurately so as to butt perfectly. There
are as many joints as there are staves and as these must be kept tight, a large
number of hoops must be used to keep the staves together.
My invention has for its object a cheaper, simpler and more rapid process of
manufacturing wooden barrels, tubs, pails and the like, from one single plank of
wood, whereby the barrel has only one joint and requires but few hoops to keep it
tight. It is also much easier to fit bottoms in barrels made in one piece according
to my process, than to provide the staves with grooves in which said bottoms enter.
In order to manufacture wooden vessels with walls made of one single piece, I
proceed as follows:-
By means of a veneering machine which need not be of a special construction
or type, but large and strong enough for the purpose in view, I cut out of round
timbers which have been steamed, planks having the thickness of the wall of the
receptacle to be manufactured. This thickness can vary from the thinnest veneer
to 5 of an inch and more if necessary.
The length of the plank depends of course upon the width of the machine and
planks of the required length can be at once obtained by cutting the tree trunk
into blocks having the length of the vessel to be manufactured.
The forming of these planks into vessels of varied shape and form is very
simple.
After they have been dried by suitable means, the planks are bent to a cylindrical
shape and have their two edges brought together. In order to manufacture a
conical vessel, the flat rectangular plank is cut so as to form a trapezoid and
then bent so as to bring its butting edges together.
One of the parallel sides of the trapezoid may be provided with saw cuts. If
both ends of the plank are provided with saw cuts, a barrel of convex or bellied
shape will be formed by bringing the butting edges together.
Any other form of vessel can easily be made out of flat planks.
As material for the new vessels I use preferably soft woods, such as poplar, alder,
aspen and the like.
In order to render the vessels made of these woods more suitable for the con-
veyance of butter, they are then fitted with a lining consisting of veneer of oak

page_text: or other wood which must be thin and which fats cannot penetrate or at least
with difficulty. This lining should be such as not to communicate any smell
to the contents of the barrel.
It is clear that vessels made in this manner must be much cheaper than coopers'
goods made by the old process; for butter casks and other dry goods more
especially, the difference in price is enormous.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what
I claim is:-
1. A vessel or barrel having its periphery made of a single slab of wood, cut as
a veneer and bent till its edges are brought into butting contact, substantially as
described.
2. A vessel made as above described and provided with a thin veneer lining
of suitable wood, substantially as and for the purpose set forth.
3. The herein described manufacture of wooden barrels or vessels by cutting a
slab as a veneer from a round block of steamed timber and bending it till its
edges meet.
4. The herein described method of varying from the cylindrical shape by suitable
saw cutting of the parts where the diameter is to be lessened.
