HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Solicitors of
Patents, of 67, Strand, in the City of Westminster, Civil Engineer. "IMPROVEMENTS
IN MACHINERY FOR MAKING BARRELS." A communication from abroad by
Frederick Jasper Chadwick and Alfred Sharpe, both of Guelph, in the Dominion of
Canada.
My Invention has relation to the manufacture of that variety of barrels and
similar packages wherein the cylindrical body is formed or built up of two layers
of wood-veneer so disposed as to cross the direction of their respective grains. The
object I have in view is to provide a single machine with which the body may be
formed and held while the hoops are run on and fastened, and also by means of a
pair of circular saws to equalize the ends of the finished body. To this end my
Invention consists mainly in a slotted sheet metal cylinder or form, over which the
body is formed and arranged to collapse so as to permit the finished body to be
withdrawn, also in combination with a rotary collapsible form, a series of guides in
a swinging frame and a guiding press roll journaled thereon for directing the hoops
upon the body, and to compress the whole upon the form until all the parts are
firmly secured together, also in combination with the said rotating form a pair of
circular cut-off saws mounted on an arbor in a vibrating frame for equalizing the
ends of the completed body and in the general construction and arrangement of the
various parts.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Herbert John Haddan in the Great Seal Patent Office on the
22nd July 1879.
HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Solicitors of
Patents, of 67, Strand, in the City of Westminster, Civil Engineer. "IMPROVEMENTS
IN MACHINERY FOR MAKING BARRELS." A communication from abroad by
Frederick Jaspar Chadwick and Alfred Sharpe, both of Guelph, in the Dominion of
Canada.
My Invention has relation to the manufacture of that variety of barrels and
similar packages wherein the cylindrical body is formed or built up of two layers
of wood-veneers so disposed as to cross the direction of their respective grains.
The object I have in view is to provide a single machine, with which the body
may be formed and held while the hoops are run on and fastened, and also by
means of a pair of cirular saws to equalize the ends of the finished body. To this
end my Invention consists mainly in a slotted sheet metal cylinder or former, over
which the body is formed and arranged to collapse so as to permit the finished
body to be withdrawn, also in combination with a rotary collapsible former, a
series of guides in a swinging frame and a guiding press-roll journaled therein for
directing the hoops upon the body, and to compress the whole upon the former
until all the parts are firmly secured together, also in combination with the said
rotary former, a pair of circular cut off saws mounted on an arbor in a vibrating
frame for equalizing the ends of the completed body, and in the general construc-
tion and arrangement of the various parts as more fully hereinafter set forth.
Figure 1 is an end elevation with the head of the former partly broken away.
Fig. 2 is an elevation of the clamp.
Fig. 3 is a plan of the press-roll.
Fig. 4 is a front elevation of the machine.
Fig. 5 is a plan view.
Fig. 6 is an enlarged end elevation of the forming drum.
Fig. 7 is a longitudinal section at 3, y, in the Drawings.
A represents the base of the machine, upon one end of which two standards B, B,
are erected, and through which a shaft C is journaled, and is provided with fast
D is a
and loose pulleys, so as to be rotated by belts from a countershaft C' below;
drum or cylinder of sheet metal mounted on heads D¹, D', keyed on the over-
hanging end of the shaft C, the drum D is longitudinally slotted or cut from end to
end, and one edge is not secured to the heads, so that being elastic it can be sprung
inwardly or partially collapsed (the corresponding parts of the heads being cut
away for that purpose) so as to permit of the withdrawal of the finished body.
E is a frame, whose foot is pivotted by a rock-shaft d to the base A, a treadle b
at the end of the rock-shaft engaging with an adjacent ratchet b¹ serves through a
cord c attached to said shaft and to a girt of the frame to draw up the latter and
to secure it in a vertical position. The frame has a bracket at one end which comes
under and supports the overhanging end of the shaft C when the said frame is
swung into position. F is a press roll journalled in the frame E, which is slotted
where the rock shaft d passes through it to allow a limited vertical play of the roll
as the work passes between it and the drum; this press roll has a series of
grooves; d each of which receives a hoop and presses it to place on the barrel.
On a girt of the frame E a series of curved shoe guides e is secured, one in line
with each grooved; in the press roll a roller el is transversely pivotted in each shoe,
and under it the hoop passes while being directed to the press roll.
A folding press-bar G¹ is pivoted to a pair of brackets on the front side of the
frame E, whose function is to bend down the veneer sheet as it goes into the
drum.

page_text: The drum is normally expanded into a true cylinder, from which it would not be
easy to remove the finished body; it is therefore made to collapse to permit the
withdrawal of the body. The heads D' each enclose a little more than half the
end while nearly all the rest has fastened in it a crescent shaped head D, each of
which is connected on the inside by a link f, with an eccentric G journalled in the
heads D, and which eccentric shaft may be rotated by an external lever g to throw
out or retract the free part of the cylinder body.
Just inside the stationary lip of the cylinder there is a clamp-bar h, with an
inwardly turned arm at each end that is pivoted to a lever i, pivoted on the out-
side of each head D'; by means of these levers the clamp bar may be thrown
forward to compress the edge of a sheet of veneer against the lip of the cylinder,
where it is held by engaging the long arm of each lever with a spring catch
His a frame, whose foot is pivoted to the base behind the drum; on each end of
an arbor journalled through said frame a circular saw I is mounted, and the arbor
is arranged to be driven when the saws are moved towards the drum, so as to cut-
off or "equalize" the projecting ends of the body.
The barrel is made in two layers of veneer, the inner one is a single sheet
disposed with the grain circumferential to the axis of the barrel while the outer
thickness may be in two or more sheets, whose grain runs parallel with the
axis.
A saw frame is thrown back as represented in dotted lines in Fig. 1; the press
roll frame is also placed in the vertical position over the drum, whose clamp bar is
retracted. A sheet of veneer is introduced in the slot of the drum and clasped fast;
the drum is then rotated about one fourth of a revolution; the drum is then
rotated about one fourth of a revolution, the sheet bending around it closely as it
passes under the press roll; an outer stave sheet is then laid on, and the drum
rotated until its edge passes behind the press roll, a set of hoops k, Fig. 1, are then
laid in the guides, and passed through the grooves in the press roll and on to the
second sheet, and nailed fast to both sheets, the ends of the nails being "clinched "
on the iron drum; the drum is again rotated and arrested when the edge of the
stave is under the press roll where a second sheet is introduced and laid against the
edge of the first one, nailing each stave sheet through the hoops and along the
edges as it passed behind the press roll.
This process
is continued until the inner sheet is entirely covered by the
outer thickness of the stave sheets when the ends of the hoops are overlapped and
nailed through and through; the equalizing saws are then brought into requisition
to trim off the projecting ends of the body which is rotated with the drum during
the process.
The end of the inner sheet is then unclamped, and the press-roll frame retracted,
as shown in dotted out line in Fig. 1.
The eccentric shaft is then rotated so as to partially colapse the drum as seen in
dotted outline in Fig. 6, when the body of the barrel may be withdrawn from the
drum. In order to secure the ends of the hoops and the edge of the first stave
sheet in position until the barrel, a clamp bar J, Fig., 2, is dropped over them and
hooked under the ends of the drum, where it is left until the free ends of the hoops
are ready to be lapped and fastened.
With one man and two boys a barrel body can be easily completed in each six
minutes of time. It is not essential to have the press roll made to swing as
described, as it is evident that said press roll can be placed in a fixed support above
the drum, and be pressed down by a supposed spring.
What I claim as my Invention is,—First. In a barrel forming machine, substan-
tially as described, the combination with the slotted metal drum D and its
heads D', D, of the eccentric shaft G and links f, f, for expanding and contracting
the covering D of said drum, substantially as described. 2nd. In a barrel
forming machine, substantially as described, the combination of the press-roll with
the collapsible drum, substantially as described. 3rd. In a barrel forming machine,

page_text: substantially as described, the combination of the press roll and a series of hoop
guides with the collapsible rotary drum, substantially as set forth. 4th. In a
barrel forming machine, substantially as described, the combination of the equalizing
saws and their swinging frame with the rotary collapsible drum, substantially as
described.
In witness whereof, I, the said Herbert John Haddan, have hereunto set my
band and seal, this Twenty second day of July, A.D. 1879.
