PROVISIONAL SPECIFICATION.
Improvements in Cask Making Machines.
I, ALLEN RANSOME, of Stanley Works, Kings Road, Chelsea, in the County of
Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows
It is usual to pass the staves between top and bottom cutters to curve their
backs and inner faces, the staves being propelled by means of a dog fixed to an
endless chain or chains. If however the stave happens to be twisted it is apt to
escape from the dog or if the dog be made sufficiently high to prevent this it is
liable to come into contact with the top cutter.
According to this invention I overcome this difficulty by hinging the dog to the
chain or chains so that if the rear end of the stave rises by reason of the stave
being twisted the dog rises with it and still holds it securely but when the rear end
descends again as it comes to the cutters the dog descends with it and passes clear
between the cutters.
Again if the stave is twisted, as the rear end comes to the cutters the front end is
apt to lift off the table and when the rear escapes from the rear guide the front end
drops suddenly causing uneven work. I overcome this objection by providing a
hinged flap or support at the end of the table which is caused by a counterbalance
weight to incline upwards. This flap or support receives and supports the front
end of the stave just as the rear end is approaching the cutters but it gives way and
turns down to allow the dog to pass. In some cases I employ a roller as the
support and the counterbalance weight may be replaced by a spring.
In order to regulate the capacity of the cask by varying the distance between
the heads, I fix the crozing cutters which form the groove for the head upon a
spindle working in the main spindle (carrying the chiming and other cutters) which
is made in the form of a sleeve. The outer end of the internal spindle is carried in
a bearing on a slide actuated by a hand wheel so that the crozing tools can be
moved to and fro at pleasure.

COMPLETE SPECIFICATION.
Improvements in Cask Making Machines.
I, ALLEN RANSOME, of Stanley Works, Kings Road, Chelsea, in the County of
Middlesex, 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 :-
It is usual to pass the staves between top and bottom cutters to curve their backs
and inner faces, the staves being propelled by means of a dog fixed to an endless
chain or chains. If however the stave happens to be twisted it is apt to escape from
the dog or if the dog be made sufficiently high to prevent this it is liable to come
into contact with the top cutter.
According to this invention I overcome this difficulty by hinging the dog to the
chain or chains so that if the rear end of the stave rises by reason of the stave
being twisted the dog rises with it and still holds it securely but when the rear end

page_text: descends again as it comes to the cutters the dog descends with it and passes clear
between the cutters.
Again if the stave is twisted as the rear end comes to the cutters the front end is
apt to lift off the table and when the rear escapes from the rear guide the front end
drops suddenly causing uneven work. I overcome this objection by providing a
hinged flap or support at the end of the table which is caused by a counterbalance
weight to incline upwards. This flap or support receives and supports the front end
of the stave just as the rear end is approaching the cutters but it gives way and
turns down to allow the dog to pass. In some cases I employ a roller as the
support and the counterbalance weight may be replaced by a spring.
In order to regulate the capacity of the cask by varying the distance between
the heads, I fix the crozing cutters which form the groove for the head upon a
spindle working in the main spindle (carrying the chiming and other cutters) which
is made in the form of a sleeve. The outer end of the internal spindle is carried in a
bearing on a slide actuated by a hand wheel so that the crozing tools can be moved
to and fro at pleasure.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation and Figure 2 is a plan of a stave cutting machine to
which my invention is applied.
A is the main shaft driven by a belt on the pulley A¹. B is a pinion on the
shaft A gearing with a wheel B₁ on the same axis as the pinion B which gears
with the wheel C on the shaft C' on which are also the chain wheels D. EE are
the chains passing over the chain wheels D and D'. F is the table on which the
stave rests and G are dogs hinged to the chains E. One of the dogs and the chains
are shown in side and end elevation to a larger scale at Figures 3 and 4. H and
Hare the upper and lower cutters respectively, they are driven by pulleys h and
belts not shown in the drawings. The bearings for the shaft of the former are
carried on brackets jj on a slide J which is suitably moved up and down by the
connecting rods K, rocking shaft K' lever K' and cam K³, the latter being fixed on
the shaft C. The lower cutter H¹ works in fixed bearings. L is a flap hinged
at L' to the end of the table, it has fixed to it the arm L2 carrying the weight L³.
Figure 5 is a longitudinal section of the arrangement for varying the position of
the groove for the head of the cask. M is a swinging frame pivotted at M¹ M' and
provided with bearings M' M' for the main spindle N carrying the chiming and
other cutters which is driven by a belt on the pulley N'. Inside the spindle N is
another spindle O carrying the crozing cutters, it revolves with the spindle N being
prevented from turning by checks S and capable of being moved endways in it, its
upper end working in a bearing on the slide P which can be traversed by the hand
wheel Q. Figure 6 is an end view of the cutters.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Hinging the dog (whereby the staves are propelled through the cutters) to
the chain, substantially as described.
2. The support at the end of the table substantially as described.
3. Mounting the crozing cutters upon a spindle working inside the main spindle
and movable longitudinally relative to it substantially as described.
4. Cask cutting machines substantially as described and shown in the drawings.
