PROVISIONAL SPECIFICATION left by the said Herbert John Haddan at

The Invention relates to a machine designed to manufacture stave barrels, and it
consists essentially of a cylindrical frame supported on a spindle by arms arranged
to fold down in order to allow the cylinder to collapse, to enable the barrel to be
withdrawn after having been built on the cylinder. An open frame made in two
halves and curved to fit the form of the barrel is arranged to carry the spindle
supporting the cylinder, and also supports the machinery for imparting a rotary
movement to the cylinder, and to a series of endless belts or chains, arranged to
feed the staves onto the cylinder; peculiarly formed cutting knives and saws are
also driven upon the frame, and arranged to cut off the ends of the staves, and to
form the recess for holding the heads within the barrel.
This barrel machinery is designed specially to form barrels made from veneer,
but may also be utilized for ordinary stave barrels.

HERBERT JOHN HADDAN, of Kensington, Middlesex. "IMPROVEMENTS IN
BARREL-MAKING MACHINERY." A communication from abroad by William Stewart,
of Guelph, in the Province of Ontario, Canada.
The object of the Invention is to produce a machine in which a bulge barrel can
be made ready for its ends, and it consists essentially of a cylinder made in two or
more pieces, and arranged to receive the staves forming the barrel, the said cylinder
being operated in conjunction with cut off saws, designed to cut off the staves and
form the recess to receive the heads of the barrel.
Fig. 1 is a side elevation, shewing all parts of my machine; Fig. 2 is an end
view, shewing the frame dropped back to permit the removal of the barrel; and
Fig. 3 is an end view of the machine, with the frame closed in the position it is
while the staves are being set upon the cylinder; Fig. 4 is an end view and sectional
side view of my cylinder, set out in the position it will be while the barrel is being
formed upon it, and Fig. 5 a similar view of the cylinder as it will appear when
collapsed, to permit the removal of the barrel; Fig. 6 is a detail of the cut off and
chamfering saws; Fig. 7 is a detail of one side of the frame for holding the staves
on the cylinder; Fig. 8 is a detail of the chain used for carrying in the staves.
A is a cylinder shaft supported by the two standards; B, C, is an adjustable
frame pivoted on the shaft D, which frame is carried in suitable bearings on the
bed plate E; F is a short frame, one end of which is pivoted to the frame C, as
indicated, its other end being provided with a catch to lock it to the frame C when
closed in the position indicated in Fig. 3; G is a support for carrying the frame C
when it is thrown back in the position shewn in Fig. 2; H is a frame corresponding
with the ribs of the short frame F, and fastened to the frame C as indicated, with
the view of holding the sleeves to the cylinder. The cylinder is composed of the
plates I supported by the arms J, which are pivoted on sleeves J', made a sliding
fit on the cylinder shaft A. Each of the plates 1, in addition to being carried by
the arms J, is provided with a link K connecting it to a sliding sleeve K'. This
sliding sleeve K¹ is operated by a forked lever K2, suitably pivoted as indicated,
and arranged to slide the sleeve K' on the shaft A, in order to collapse or expand
the plates I forming my cylinder.
One end of the shaft A is provided with a spur wheel L which meshes into
pinion L. Upon the spindle of this pinion is keyed a large pulley L², which is
caused to revolve by the action of the small friction pulley M, whenever the same
is caused to come in contact with it. This friction pulley M is keyed to an
adjustable shaft MI, which when the machine in operation is constantly revolving.
Whenever it is desired to make the shaft A revolve a given distance, the shaft M'
is moved so that the friction pulley will come in contact with the larger friction
pulley M. The shaft D is driven by the belt D', a loose or fast pulley being placed
upon the shaft D, so that it can be made to revolve or not as required. From this
shaft the belts N drive the spindle N¹ situated at either end of the cylinder. On
the inner end of this spindle I key or otherwise secure the cut off and chamfering
saws M', the formation of which is clearly shewn in Fig. 6.
When the frames are closed together, as shewn in Fig. 3, a bracket C' is arranged
to support the outer end of the shaft A.
Each spindle N is provided with a pivoted hand lever N2, which is designed to
move the spindle longitudinally within their bearings which carry them on the
frame C.

page_text: Having now described the general construction of the machine, a few words will
suffice to explain its operation.
Having put a loop over the cylinder and pushed it towards the standards B,
the frames C and F are drawn and fastened together, when the machine will
present the appearance shewn in Fig. 3. The staves are then placed on top of the
support G and fed in between the cylinder and the ribs of the short frame F, the
cylinder being caused to revolve by the mechanism before described at each time
it is desired to feed a stave. While the staves are thus being fed in, the cut off and
chamfering saws are cutting the ends of the staves off and forming the necessary
recess to receive the ends of the barrel. When a sufficient number of staves have
been fed in to complete the barrel, the end hoops are knocked on & the frames C
and F thrown back in the position shewn in Fig. 2, when the barrel thus
completed may be withdrawn off the ends of the shaft A. In order to assist in
feeding the staves a chain O, as shewn in Fig. 7,. is applied to the short frame F,
as indicated in the Drawing.
What I claim as my Invention is,-
In a machine for making barrels in which the staves are arranged around a
cylinder built in segments, carried by arms extending from a shaft in such a manner
that the cylinder may be expanded to the required diameter of the barrel, or
collapsed to permit the removal of the barrel when finished. An adjustable frame
arranged to support the cylinder with chain stave feeder attachment and mechanism
for imparting a rotary motion to said fraine, in combination with a combined cut off*
and chamfering saw situated one at each end of the cylinder, and caused to revolve
so as to cut off the ends of the staves, and at the same time form a recess at
each end of the barrel for the reception of the heads.
In witness whereof, I, the said Herbert John Haddan, have hereunto set
my hand and seal, this Twenty-third day of January, A.D. 1882.
