Improvements in Machines for Making Barrels.
We, WILLIAM THOMAS VALE, of No. 13 Howard Street, in the City of
Toronto, in the County of York, and Province of Ontario, Canada, Manufacturer,
and ALEXANDER BUNTIN, of No. 29 Wellington Street West, in the said City of
Toronto, Merchant, 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:-
The object of the invention is to devise a machine for making tight barrels
which will be both simple in construction and effective in operation, and it consists,
essentially, of such improvements in the barrel former, the sweeps retaining the
exterior of the barrel in shape, the stave feeding apparatus, and the stave hollowing,
crozing, chamfering and equalizing mechanism, as are hereinafter more specifically
described and then definitely claimed.

In the drawings like letters of reference indicate corresponding parts in the
different figures.
A, is the frame of the machine, suitably shaped as shown to support the different
parts.
B, is the former shaft supported in suitable bearings on the standards C, D,
and E of the frame A.
The standard E is divided in two parts, as seen in Figs. 1 and 2, which halves
are pivoted at a to the frame of the machine. F, is a headed pin against which
the inner portion of the base of each half of the standard E is fitted, the head of
the pin holding the parts securely in contact with the base on which they are
adapted to turn. It will be noticed that the halves of the base of the standard E
are notched at b so as to permit the halves to be swung outwardly while the
shoulders of the notches act as a stop to limit the inward motion (see Figs. 1
and 2).
Before describing the construction of the former itself, it will be advisable to
describe the general construction of the other parts of the machine.

page_text: In Figs. 1, 2 and 7, T T are the sweeps or curved half rings which serve to
give shape to the outside of the barrel." As will be seen in the drawings, there
are four sets of these half rings so located as to form two substantially continuous
rings near each end of the barrel. The rear sweeps T are rigidly connected to
the shaft U and the front sweeps are similarly connected to the shaft V. It will
be noticed that each half ring T is slotted at c to embrace the shaft V and that
the half rings T are similarly slotted at.d to embrace the shaft U. These slots
are so proportioned as to permit of the sweeps assuming either the position shown
in Fig. 1, or the position shown in Fig. 2, motion being conveyed to them by the
revolution of the shafts U and V. In Fig. 7, is seen more particularly the
mechanism used for giving these,shafts a simultaneous motion.
e is a pinion fast on the end of the shaft U, and is a pinion, fast on the
shaft V. These pinions are, of equal, size, and mesh. with
as shown.
one.. another,
g is a hand. lever connected to one of the pinions e & f. From this construction
it will be seen that by moving the lever g, the sweeps may be made. to assume
either of the positions already described at the will of the operator.
In order to balance the weight of the sweeps and thus facilitate the movement
of the same, we connect to the shaft V two arins (see. Figs. 1, 2 and 7). Oa
these arms are hung the weights i. As the tendency of the sweeps is to fall
downwards, and the tendency of the weights is to so revolve the shaft V. as to
maintain them in their vertical position, or to return them thereto, the weight of
the sweeps may be very accurately counter-balanced.
Within the sweeps T T'are the former heads j rigidly secured to the former
shaft B and each horizontally located in a position substantially, midway between
the two rings formed at each end by the half-rings. T T', as indicated in Fig. 1.
kare ring segments shaped substantially as shown and adapted to slide,between
the guides m (see Figs. 4, 5, and 6).
n are plates screwed as shown to the guides m and overlapping the stems of the
ring segments k so as to hold them in place. The ends of each segment are
notched as shown at o so as to permit the ends to overlap when the rings are in
either their extended or collapsed positions. From this construction it follows
that the ring segments may be made to occupy the position shown in Figs. 1. and 5.
so as to form a complete ring, or may be collapsed below the edges of the former
heads so as to permit of a barrel being removed from the former.
Each ring segment is slotted at p to permit of the bars sliding therein, the
former heads having long slots formed therein for the passage of the bars.
These bars are shaped as shown, and are provided with inclined. planess and t
adapted to force the ring segments k inwardly and outwardly when the bars are
reciprocated. These bars r slide through a head z fast on the former, shaft B,
their other ends being connected at u to the sliding, head. v. This head, has a
pin passing through its hub and through slots w in the hollow end. of the former,
shaft B. This pin also passes through a roda, the other end of which is provided
with the handle y by means of which it may be moved longitudinally. Spring-
operated catches A are also provided. for holding.it in position when the sections
of the former are extended substantially as in other machines..
From this construction it follows that when the rod a is moved in the direction
indicated by arrow in Fig. 4, the ring segments.k are forced.inwardly (see Fig. 2)
and that, when it is returned again to its original position, the segments are forced,
outwardly to assume the position shown in Figs. 1, 4 and 5.
The outer sweeps T' at the front of the machine have the stave carrier guides B¹
formed on or connected thereto. These guides, as shown in Figs. 8.aud 9, are
suitably shaped to fit the heads C which slide thereon. To these heads.are bolted
the ends of the stave carrier S which has fingers D' connected thereto to retaju, the.
stave in position. Mechanism is provided for reciprocating the stave carrier on
the guides B' as hereinafter described.
It should be noted here that the upper part G¹ of each of the outer sweeps T¹ is
.

page_text: suitably shaped to guide the stave in below the inner edges of the sweeps T, the
outer surface of the guides B being substantially flush with the part G. E' are
the stave guides (see Figs. 1, 2 and 8). One of these guides is connected at a' b²
to each end sweep T¹ so as to stand out at some distance laterally therefrom.
Each guide is provided with a flange F beneath which the end of the stave
passes so that it is held down tightly against the surface of the upper portion G
of the outer sweeps T.
It will be noticed that at H' a portion of the flange F is cut away so that the
stave N may be pressed down so as to be in a position to pass underneath. the
flange. Connected to the inner surface of the upper portion G' of each of
the outer sweeps T is a curved spring I bolted at c to the sweeps, as shown.
As each of these springs projects slightly above the surface of the upper part G
of the sweep, it will press the stave with a spring pressure against the lower
surface of the stave guide E thus holding the stave very firmly while it is being
operated upon by the cutter heads, as hereinafter described.
It will be noticed.that-the springs are shaped as an inclined-plane, up which the
staves are driven till they reach the portion of the spring normally highest above
the surface of the upper portion of the sweep. In Fig. 8 is indicated the normal
position of the spring in full lines and in dotted lines the position it assumes when
pressed down by the passage of the stave.
Journalled in the portions G of the outer sweeps T' is the cutter shaft J'.
This shaft is provided with the driving pulleys K and also with the cutter
heads L' which are located as shown in Fig. 1 beneath the stave guides E'. Each
cutter head carries. crozing saws M', hollowing tools N', chamfering knives O¹ and
an equalizing saw P₁ which latter projects through a slot in the stave guide E' as
shown in Fig. 8. This slot is preferably covered by a saw guard Q. In Fig. 1,
the guards are removed exposing the slots in the saw guides, and in both Figs. 1
and 2 the equalizing saws are omitted to show the parts behind.
On reference to Figs. 3 and 2, the arrangement of the mechanism for imparting
motion to the cutter heads and the stave carrier will be readily understood.
In Fig. 3, G, is a shaft journalled on standards Cand D. This shaft carries the
tight and loose pulleys H, and I, and also at one end the pinion J, meshing with
the spur wheel K on the end of the shaft L, which is suitably journalled on the
frame A of the machine.. The other end of this shaft carries a crank disk M on a
wrist pin on which is journalled the pitman N (see Figs. 1 and 2), the other end of
which is pivoted to the lever O fast on the-shaft P, suitably journalled on the frame
of the machine. Two levers Q are also connected to this shaft and are pivoted at
their outer ends to the connecting rods R which are pivoted at their other ends to
Jugs formed on the stave carrier S (see Fig. 1).
From this construction it follows that a reciprocating motion will be given to the
stave carrier through the rotation of the shaft G. As it is desirable to be able to
regulate the extent of this motion, the lever O is preferably slotted at R' and the
end of the pitman N connected with the pin a" adjustably held therein. It will
be readily seen from. this construction that the exact amount of throw of the
stave carrier S will depend upon the point of pivotal connection of the pitman N
to the lever O.
It will be noticed that the end of the pitman N is slotted to slide on the pin all
so that the carrier and the parts connected thereto will be left at rest for a
short time after feeding a stave to the machine and returning to its first position.
While the carrier is left at rest, its heads C¹ rest on the stops on the guides B'
(see Fig. 2).
Again referring to Fig. 3, S¹ is a shaft suitably journalled on the frame of the
machine. On this shaft are the tight and loose pulleys UV. On the other end
of the shaft are rigidly connected the pulleys A (see Fig. 1) B (see Fig. 3).
In Fig. 1 are shown the idler pulleys C connected to the shaft D" journalled on
the frame of the machine. E are idler pulleys each journalled at the end of an
arm F connected to the shaft G" journalled on the frame of the machine., A

page_text: "belt passes round the far pulley K' on the cutter shaft, thence round one of the
idler pulleys C, thence round the pulley A", round the idler pulley E" and back
to the far pulley K'. The near pulley K' is similarly driven from the pulley B
The weight of the idler pulleys E" and the arms to which they are connected, is
Rufficient to keep the driving belts tight on the cutter shaft pulleys, but weights
may be suspended from the arms if necessary.
In Figs. 1 and 2 will be seen the locks H, one of which is pivoted to each of
the outer sweeps T. These pivoted locks are connected together by a bar I and
are notched at J to engage with the curved bar K" connected to the ends of the
stave guides E'. These locks, when engaged with the bar K serve to retain the
sweeps T T in closed position while the barrel is being formed.
A finger el is pivoted on, the post d" connected to the bar K. By swinging
this finger above the bar 1 the locks H" are held securely in contact with the
said bar, while, by pushing back the finger, the bar I" may be freed so that it may
be lifted,
It will be noticed on reference to Figs. 1 and 2, that the central sweeps T are
provided with pivoted locks L" which serve to guide the staves below the inner
edges of the sweeps T. At the same time when the first stave is forced onto
the former, the points of the pivoted locks will prevent it sliding forward
and falling down the front side of the former. When the last stave is to
be placed in the machine, the first stave having passed completely round the
former will come into contact with the other side of the points fl of the pivoted
locks L" and will be securely held while the other staves are forced against it
and the last stave placed in position. el is a bar connecting the outer ends of
the locks.
To prevent binding and unnecessary friction and waste of power, we connect to
each outer sweep T a curved spring M" which is held at each end similarly to
the curved springs 1' and which starts from a point below the inner edge of the
sweep and gradually rises above it (see Fig. 7). This spring always maintains a
pressure upon the staves, and at the same time will yield to prevent binding of the
'machine if the staves may happen to be somewhat thicker than usual or present
other inequalities of surface. We do not consider it necessary in this machine that
the former itself should revolve, but provision may be made for doing so, if required.
In Fig. 1, is seen the support O" for the end hoops which are to be placed on
the barrels.
Having set out the construction of the machine, we will briefly describe its
operation―
When ready for operation, the parts are all in the position shown in Fig. 1, and
the loose pulleys on the shaft G and S are connected by belts with the line shafting.
By shifting these belts onto the tight pulleys, the machine is set in operation and
the cutters commence to revolve and the stave carrier to reciprocate on its guides.
A stave is then placed on the carrier behind the fingers D' and is carried forward
under the flanges F', which, as before stated, are cut away at H' to permit of the
ends of the staves passing beneath them. The carrier then returns to its first
position and another stave is inserted, which is carried forward like the first and
pushes it over the cutter heads L' where it is properly hollowed, erozed, chamfered
and equalized, the curved springs 1 holding the staves rigidly while this is being.
done. Another stave is then inserted and carried forward as before, pushing
forward the second stave into position to be operated upon by the cutter heads. By
the time the fourth stave has been inserted, the first stave has been pushed forward
over the pivoted locks and under the upper portions of the sweeps resting against
the points of the locks. This process is continued till sufficient staves have
been put into the machine to complete the barrel. The stave carrier $ pushes up
this last stave and returns to its normal position. It follows that three of the
staves required to form a barrel are left on the feeding apparatus, thus leaving a
vacancy for three staves in the former. These last three staves may be fed into
the barrel either by putting fresh staves on the carrier so as to push the last thre

page_text: into their place in the harrel, but by this method, the bar el of the pivoted
locks L will be covered by the staves so that it is difficult to get at it to operate
them. The apparatus shown in Figs. 10 and 11 are therefore provided. This
consists of a frame composed of the curved bars g; stave h¹ and cross bar i¹.
Handles are preferably connected to the curved bars g Locks are
connected to each of the curved bars g" in the position shown. It will be noticed
that the curved bars g" stand out from the stave . The object of this is to
permit the fingers D' on the stave carrier S to fit underneath them. When used with
this frame, the fingers D' are preferably cut off short, as indicated in dotted lines in
Fig. 9. This frame is used by placing the stave on the stave carrier. This enables
the stave carrier to push one more stave onto the former. When the stave carrier is
operated, the first set of lugs are caught on the fingers D'and another stave is forced
onto the former; when the stave carrier again retreats, the last set of luga " are caught.
on the fingers D' and the last stave thus forced onto the former. The machine is then
stopped by shifting the belts the bar el depressed to raise the points fl of the
locks L and a hoop removed from the support O and put on the end of the
barrel. Another hoop which has previously been hung over the former shaft B is
placed on the near end of the barrel which is then ready for removal. The bar "
is then lifted upward, and the locks H" thus raised from the curved bar K". By
operating the hand lever g, the sweeps are then swung into the position shown in
Fig. 2. The handle y is then grasped, the spring-operated catches A¹ released,
and by pulling on the handle, the ring segments of the former collapsed, as already
described. The halves of the standard E are now swung open and the barrel
removed from the former, ready to receive the heads and the other hoops.
In Figs. 12 and 13 is shown the mechanism for trussing the barrels before they
are removed from the former.
a are half rings pivotally connected together at 611 and also pivoted at e
and f to the blocks g and . The block 9 is supported on the shafts. U
and V, and the block slides upon the block gl as shown.
is a
spindle having right and left-hand threads formed thereon. The spindle
passes through similarly threaded holes in the blocks gland so that by
revolving the spindle, the blocks may be drawn closer together or moved farther
apart. Suitable gear wheels are placed on each of these spindles and are
driven simultaneously by the pinion which may be revolved by hand or in any
other suitable manner.
When the barrel is formed, the former is partially collapsed and the spindles
operated to close the half rings all upon the barrel and thus tightly truss the
staves together. This operation is performed before the end hoops are placed in
position, as already described. When it is desired to move the barrel from the
former, the half rings all are loosened and their upper pivots 6 are withdrawn.
The half rings then drop entirely out of the way and the barrel is removed, as
already described.
It should be mentioned that the staves are preferably bent in suitable rolls before
being placed in the machine. The parts of the invention which we deem of
particular importance are:-
1. The construction of the former which is very simple and yet exceedingly
strong and perfectly rigid when in its extended position.
2. The method of supporting the outer end of the former shaft by the divided
standard E, which gives a perfectly rigid bearing for the shaft and yet may be
instantly opened up to permit of the removal of a barrel.
3. The construction of the sweeps which are pivoted and counter-balanced so as
to be much more easily and simply operated than in former machines where they
have been arranged to slide.
:
4. In the use of a sliding feed connected to the front sweeps of the machine
instead of a roller feed connected to a separate swinging frame, such as has been
previously used.
5. In the similar location of the cutter shaft and cutter heads.
