This Invention has relation to improvements in the construction of that class of
barrels and cylindrical packages which are made from wood veneer, or thin sheets
of wood cut directly from the log by a knife, and the object of the Invention is to
produce a cheaply constructed bulge barrel of this material. The Invention consists
in dividing the sheets of wood into sections of a stave form, and in forming the
barrel of two thicknesses of staves, which are so arranged that they shall break

barrel may be withdrawn from the form. In the manufacture of barrels embodying
the Invention each stave is properly shaped in a machine jointer to give the barrel

by the said Herbert John Haddan in the Great Seal Patent Office on the 2nd

HERBERT JOHN HADDAN, of the Finn of Herbert and Company, Solicitors of
Patents, of 67, Strand, in the City of Westminster, Civil Engineer. "IMPROVEMENTS
IN BARRELS OR CASKS." A communication from abroad by Samuel Wright,
Manufacturer, of Harriston, County of Wellington, Province of Ontario, in the
Dominion of Canada.
The first part of my Invention has relation to improvements in the construction
of that class of barrels and cylindrical packages which are made from wood veneer,
or thin sheets of wood cut directly from a log of wood by a knife, and the
object of the Invention is to produce a cheaply constructed bulge barrel of this
Inaterial.
The Invention consists in dividing the sheets of wood into sections of a stave
form, and in forming the barrel of two thicknesses of staves, which are so arranged
that they shall break joint, thus forming a barrel with an inner and outer skin.
The second part of my Invention consists of a machine in which is provided a
form or shape constructed in sections so arranged that when the barrel is completed
the sections shall collapse in order that the barrel may be withdrawn from the
form.
Referring to the accompanying Drawings, Figures 1 and 2 are side elevation and
sectional plan view respectively of a barrel embodying my Invention.
Figure 3 is a bottom plan, Figure 4 a longitudinal sectional elevation, Figure 5
a cross section, and Figure 6 an end view of a barrel forming machine, in which
my improvements are embodied; Figure 7 is a detail of the saws for cutting off
the ends of the staves.
A is the inner skin, and B the outer skin, built up of staves a, b, respectively,
which staves are cut from shoots of veneer in a manner well known to inanufac-
turers. Each stave is properly shaped in a stave jointing machine so as to give the
required increase of diameter to the central portion of barrel when built and
fastened into place. The joints of the stave on the one skin are placed to overlap
or "break" with the joints on the other skin so as to prevent the contents of the
barrel escaping. C is a hoop nailed near each end of the barrel to form a retaining
shoulder for the head D, which head is secured in place by an outer hoop Ĕ
nailed to the staves when the barrel is filled.
The advantage of my improved construction is that strong well made bulge
barrels can be made from veneer cheaply and rapidly by machinery, with very little
waste of material, the said barrels combining all the good qualities of the ordinary
stave bulge barrel with those of the straight veneer barrel; the latter being made
in one sheet must necessarily be straight, which all shippers are aware is their
most objectionable feature.
In the manufacture of barrels of the description above described I employ a
hollow form F, which is constructed in four, more or less, sections F¹ so arranged
in connection with the hinged standards G on a shaft H. that the sections of the
form are capable of being drawn inward towards a common centre, thus reducing
the diameter of the form to the necessary extent required for the removal of the
completed barrel. The movement of the sections is accomplished by means of a
lever I, which is pivoted on the frame of machine, and is connected to a sleeve 1¹.
This sleeve is coupled by the bars 12 to one end of each section of the form, and as
it is moved operates the sections inward or outward, as desired.
As shewn in the Drawings, the form is mounted on a frame, and is connected
to and driven by gearing in a manner now well known in the manufacture of
veneer barrels. I therefore make no claim to this portion of the machine, neither

page_text: do 1 limit myself to the use of cooperating machinery of the description illustrated,
as I am aware that the construction and design of such may be much modified,
and in fact dispensed with if desired, as the barrel form can be rotated and operate l
by hand.
In the manufacture of the barrel the staves are jointed in a stave jointing
machine to give the barrel the proper amount of enlargement in the centre. The
staves are then placed in succession on the expanded form and pushed in under the
roller K, between the retaining bars J and the surface of the form in two layers,
As each stave is
with the joints of the staves arranged to overlap each other.
pushed in place the form is moved around a corresponding distance, either by power
applied from gearing as shewn, or by hand, until the whole surface of the forin is
covered with two thicknesses of staves. Prepared hoops are then driven over the
staves at each end to secure them from displacement, and nailed to the staves, the
points of the nails clinching on the metal form.
The irregular ends of the staves are then cut by means of a pair of saws L
arranged in a swinging frame, substantially as shown, and the barrel trimmed to
the length desired.
The barrel is then removed by folding back the retaining bars J, which are
hinged together, and collapsing the form.
The barrel is then completed, by the addition of the remaining hoops and heads,
by hand.
I claim as my Invention, and desire to secure by Letters Patent,-
veneer,
1. A double skin veneer barrel or package made from stave shaped strips of
"break"
the joints of the staves on the one skin being made to overlap or
with the joints on the other skin, the whole, when together, forming a double skin
bulge barrel, substantially as described.
2. A veneer bulge shaped barrel formed of the stave shaped strips a, b, in combi-
nation with the hoops C and E for retaining the head D, as specified.
3. A barrel form constructed in sections, substantially as described, and capable
of being expanded and contracted in diameter, substantially as and for the purpose
set forth.
4. The combination with the barrel form F, constructed in sections, substantially
as described, of the hinged standards G, shaft H, sleeve I', bars I, and the
lever I.
5. The combination with the barrel form F, constructed in sections, substantially
as described, of the hinged retaining bars J and roller K, substantially as and for
the purpose set forth.
6. The combination with the barrel form F, constructed in sections, substantially
as described, of the swinging cut off saws L, substantially as and for the purpose
set forth.
In witness whereof, I, the said Herbert John Haddan, have hereunto set
my hand and seal, this Second day of June, A.D. 1880.
