Improvements in or relating to Machines for Making Casks or
Barrels.
We JOHN HENRY HALL, formerly of Shirley, Sidcup, in the County of Kent,
but now of No. 47 West Bank, Stamford Hill, in the County of Middlesex,
Commercial Agent, and DENNIS PARRY, formerly of Belle Vue Llandela near
Mold in the County of Denbigh but now of No. 38 Spenser Road, Herne Hill, in the
County of Surrey Engineer, 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 this invention is certain improvements in machines for making
casks or barrels also an expansible appliance for supporting the bilge of the cask
or barrel while being formed-also an appliance for compressing the ends of the
staves together, and for forcing a temporary truss-hoop on them to hold them
together also an improvement in the arrangement for simultaneously cutting off
the ends of the staves to an uniform length-also for bevelling the inner-edge faces
of the staves and in forming the grooves in which the heads are placed-the whole
of the said appliances being combined in the same machine and acting in the
manner hereafter described.
Our invention will be understood by the annexed drawings in which at Fig. 1 is
shewn a part section. Fig. 2 is a side elevation and Fig. 3 is a plan of the
machine.
We fit uprights A A to a bed plate B B. The said uprights carry a main
shaft C taking its motion from a supplementary shaft D which is provided with a
rigger E and friction or other driving gear F F.
The main shaft C is hollow and carries within it another shaft G capable of
rotating in one or other direction by means of a clutch wheel H this being arranged
between two loose running riggers J. J driven in opposite directions by straps.
The clutch wheel H has cone faces II to engage into either rigger J J according
to the desired throw of the hand lever H¹. The opposite end of the shaft G
has a right and left hand screw on which heads K. K. can be made to approach
to, or recede from each other, according to the direction in which the said shaft G
is made to revolve. The centre heads K K carry spherical ends of bars L
arranged radially round them (as shewn in Fig. 1 and Fig. 4) within slots, the
walls of which preserve their proper action in opening and closing. The bars L
are connected in pairs at their outer ends by blocks M which can be forced outwards
to increase the diameter, or inwards to decrease it.
A couple of rings P P₁ are mounted on pivot pins P P and are supported upon
distinct yet movable standards Q. Q. capable of being set farther apart or closer
together by a right and left hand screw of an independent shaft R arranged under
the bed plate B.
To the rings P P' are attached a series of conical segments S. S. working on
hinges S to conduct the staves into the truss hoops S which are held in the
rings P P
The moveable uprights QQ which carry these rings P P₁ also carry
brackets T. T. to each of which a rotating shaft a' is fitted, said shafts a a¹
carrying each a circular saw U for cutting off the ends of the staves-said
shafts a. a' also carry bevelling cutters U₁ U' for chamfering the inside edges of
the two ends of the cask, in addition to which the same shafts a' a' have
cutters U U for cutting the groove in the inside of the staves.
For drawing the rings P P and the truss hoops S'S' over the end of the staves

page_text: into position, we use a shaft V having a right and left handed thread, and is driven
by the pulley Z.
Semi-circular nuts W W₁ sliding on bars X are brought into gear by means of
a hand lever Y the said nuts being connected to the rings P P and as they
approach each other by the action of the shaft V they draw the aforesaid rings
with them as far as required over the staves.
The operation of making a cask by this special construction or arrangement of
machinery is as follows:-
The cask being set up in the usual manner by hand, a truss hoop "6" is placed
on the bilge, and the cask is placed in the machine. The internal ring is then
expanded for supporting the bilge and holding the cask in position. The rings P PI
are next drawn over the ends of the staves by the action of the right and left
handed thread on the shaft V and the semi-circular nuts W W. The cask is now
made to revolve by means of the expanding ring, and the hollow shaft C, driven
by the friction gear F F. While the cask is revolving the circular saws U and
the cutters U U' are brought into position by means of levers a a for simul-
taneously cutting the ends of the staves and for bevelling and grooving them on
the interior.
The cask being completed, the rings P P₁ are thrown open on their hinges,
leaving the truss hoops S2 still on the cask. The expanding ring supporting the
bilge is next contracted and the cask is drawn off the machine, and is now ready
for the cooper, to be headed and hooped in the usual way.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what we
claim in machinery or improvements in machinery for making casks or barrels or
in connection therewith, is,
The construction and arrangement of cask-making machine as hereinbefore
described and illustrated in the drawings attached, in which the principal parts
are:-
1. A ring formed of conical segments S. S. working on hinges S! (as shewn in
drawings) for the purpose of conducting the staves into the truss-hoops S²..
2. An expanding ring formed of blocks M which may be contracted or expanded
by the action of the centre heads K K and the connecting bars L.
