page_text: I, ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
Engineer, do hereby declare the nature of this invention (a communication from
William Thomas Vale of the City of Toronto, in the County of York, in the
Province of Ontario, Canada, Barrel Manufacturer) 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 design a machine which can be readily adapted
to manufacture barrels of various sizes, and by which permanent end hoops may
be placed on the barrel.
It consists essentially in providing horizontally adjustable rings having detach-
able face pieces, so that the rings may be readily altered in diameter to suit
various sizes of barrels; the former being also detachable to suit any desired size
of barrel; the rings before mentioned being also adjustable longitudinally so as to
enable them to be adapted to various lengths of barrels; automatically operating
mechanism being provided for feeding the staves around the former and detachable
feed-rollers, and detachable cutter-heads being placed on the machine so that
they may be also used in connection with the manufacture of various sizes of
barrels.
Figure 1, is a perspective side view of this barrel machine.
Figure 2, is a perspective end view showing the rings expanded and the .
standard thrown back ready for the removal of the barrel.
Figure 3, is a detail of the barrel former.
Figure 4, is a detail showing the means of adjusting the cutter-head.
In the drawing like letters of reference indicate corresponding parts.
A, is the main driving-pulley which revolves loosely on the shaft, D, when the
machine is standing. The pulley, A, communicates motion by means of the
friction-clutches, B, and, C, when engaged, to the shaft, D, thence by a series' of
gear-pinions and wheels E, F, G, H, I and, J, to the sprocket-wheel, K, on the same
shaft as the gear-wheel J. The sprocket wheel, K, is connected by a sprocket-
chain to the sprocket, L, on the main frame M, of the machine. On the same
spindle as the sprocket-wheel, L, is journalled the sprocket-wheel, N, which imparts
Price di

end of the feed-roller spindle d
As represented in the drawing the machine is not in operation, as it will be seen
that the friction-clutches B, and, C, are disengaged; but immediately upon the
foot-lever, O, being tilted upon its pivot it presses the pin, c, formed on the end of
the bell-crank, P, against the hub of the main driving pulley, A, and throws the
internal friction-clutch, C, which forms part of the same hub, against the clutch, B,
thus throwing the machine into operation.
It will now be seen that by means of the series of gearing before described that
the shaft, Q, upon which the barrel-former, R, is set, will be caused to revolve as
also the feed-rollers, a, on the spindle, d.
It will be noticed that the spindle, d, is journalled in bearing-boxes on the
standard, e, and may be adjusted vertically by means of the screw-spindles, f, to
suit the size of the barrel placed upon the former R. As the barrel-former, R,
revolves in the direction indicated by arrows, the rollers, a, act upon the staves, h,
feeding them in till they reach the point indicated in Fig. 1, where they are held
up by the dogs, g, pivotted on that portion of the ring called, S. The rollers, a,
continue to act till all the staves necessary for the completion of the barrel are
fed in.
In order to prevent too great spring of the

staves h, as they are being fed in;
The hand-levers, i, are brought to
between that portion of the ring
In Fig. 2, I show the portions, S, and, T, of the ring, within which the barrel is
formed, separated to permit of its removal when formed. This is accomplished by
the hand-wheels, j, which operate the spindle, k, which have a right and left-hand
thread cut on each to permit the rings, S, and T to work from or towards the
centre of the spindle k, so as to close or open the ring. It will be seen that these
spindles are connected together by the sprocket-chain, I, on the side of the machine
opposite to the hand wheels, j. The portions, S, and, T, of each ring may be
adjusted longitudinally on the frame, M, by the set-screws 11.
Upon the inner surface of the portions, S, and, T, of the ring I attach minor
rings, 8, and t, which may be varied in thickness to suit the size of the barrel
desired to be formed.
It should have been mentioned before that there are discs, u, that pivot on the
rings, S, which press against the outer end of each stave as it is being acted upon
by the cutter-head, U.
As there is nothing different in the cutter-heads from the ordinary ones now in
use, I shall now proceed to describe the means by which they are driven and the
mode of adjusting them to the different sized barrels.
Upon the bed-plate of the main frame, M, I journal the shaft, m, which
derives motion by the belt, n, connected by the motive power. On this shaft
I place the pulleys, o, which are connected by the belts, p, to the cutter-head
shaft, q. Upon the shaft, q, I rigidly secure the collars, r. Into the recess in these
collars, I, is fitted the bent end n, of the slide, v, which may be adjusted longi-
tudinally so as to bring the cutter-head, U, into the proper position for chamfering
and sawing off the ends of the staves for the different lengths of barrels.
On reference to Fig. 4 the means of adjusting the cutter-head, U, to suit the
different diameters of the barrels, may be easily understood.
w is a hand-wheel at the end of the screw-spindle x, which passes through the
set-screw, y. The set-screw, y, extends into the box z, which supports the cutter-
head shaft, q, all of which work upon the bracket, V.
When the barrel desired to be formed is of small diameter the cutter-head may
be brought closer to the standard c; and when the barrel is desired to be of greater
diameter it may be removed farther away from the standard, e, by manipulating
the band-wheel, w, so as to bring the set-screw, y, towards the outer end of the
slot formed in the bracket, V, as shown in Figure 4.

page_text: Upon the ends of the staves of the barrel being finished by the cutter-heads, U,
the end hoops which may be suspended from the hooks, I, may be slipped off on to
the ends of the barrel as shown in Fig. 2. The drum or barrel former, R, is then
collapsed as hereinafter described and the barrel may be withdrawn.
In Fig. 3 I show the method of constructing this improved cage drum or barrel
former, R. It will be seen in this Fig. that it. is composed of four sections W;
attached by pivotted arms to the collar, Y, on the main shaft Q. Towards the
inner end of the drum or barrel-former, R, upon the shaft, Q, I place the collar, Z,
which has a flat key 2, passing through it, and the slot, 8, in the shaft, Q, which
is hollow from this point to its outer end. To this collar I pivot the arma, 3, at
their inner end while at their outer end they are connected to the arms, X, by the
pin 9. The pin, 9, passes through slots, 10, formed in the forked end of the arm, 3.
The key 2, connects the collar, Z, to the spindle, 4, at the outer end of which the
handle, 5, is attached. The handle, 5, has two bell-cranks, 6, pivotted to it, the
inner ends of which fit into the recess 7, on the end of the shaft, Q. In this
position the barrel former is held expanded ready for the formation of the barrel.
When it is desired to collapse the barrel-former or drum, R, so as to permit of
the removal of the barrel, the attendant of the machine has merely to press the
outer ends of the bell-cranks, 6, so as to remove their inner points from the
recess, 7, and draw outwardly as indicated by arrow, thus moving the collar, Z,
outwardly along the shaft, Q, and bringing the arms, 3, and, x, and consequently
the four sections closer to the shaft, the fitting points of the sections being bevelled
so as to permit one pair to fold within the other.
It will be seen from this description, that barrels can be made much more
cheaply by this machine than by those now in use; the work being such as a boy
can easily attend to. Another great advantage in this machine is the method of
adjusting the rings longitudinally on the frame, M, to suit the length of the barrel;
different sized drums or barrel formers being set on the shaft, Q, to correspond to
the position of these rings.

invention as communicated to me by my foreign correspondent and in what
manner the same is to be performed I declare that what I claim is
