COMPLETE SPECIFICATION.
New or Improved Apparatus for "Chiming" and "Crozing" the
Staves of Casks or Barrels.
I, JOHN RUSSELL of 317 Tuam Street West Christchurch, Canterbury in the
Colony of New Zealand Cooper, 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 :-
This invention relates to new or improved apparatus to be used in the manufacture
of casks or barrels, the object of which is to "chime" or chamfer, the inside edges
of the staves and to " croze recess or groove, the said staves for the reception of
the head at one operation.
By the use of this apparatus a speedier and much more uniform effect is obtained
than by the usual hand method.
The apparatus is more simple and much cheaper in construction than any
contrivance yet introduced for effecting all the purposes desired.
My new or improved apparatus for chiming" and "crozing" consists of ;-
I. A cutter head carrying suitable knives and fitted to a rotating spindle having
fast and loose pulleys and working in necessary bearings mounted on a frame for
carrying same.
II. An adjustable "cradle" to carry end of cask or barrel being operated upon,
its upper part being provided with a tongue over which a grooved hoop (temporarily
fitted on end of cask or barrel) ruus, in order to insure the said cask or barrel
turning true, such cradle being raised or lowered as desired by a lever actuated by
a screw.
III. A simple cradle to carry opposite end of cask or barrel.
IV. A winch with rope and hook to hold cask or barrel down to cradles and to
turn said cask or barrel whilst being operated upon.
In order that my invention may be more easily understood I will now proceed to
describe the same by reference to the annexed sheets of drawings wherein :-
Fig. 1 is a plan showing a cask or barrel in position, a portion of said cask or
barrel being shown broken away in order that the "cutter head" may be seen;
also showing the spindle, fast and loose pulleys and the winch.
Fig. 2 is a view showing side of winch and outer end of cask or barrel, also the
rope by which the said cask or barrel is held down and turned.
Fig. 3 is a side view showing cask or barrel in position on adjustable "cradle "
and cradle for outer end, but with winch removed; a portion of end of cask or
barrel is shown broken away in order that the cutter head may be seen.
Fig. 4 is a view showing face of cutter head and "adjustable cradle" with lever
and screw for actuating the lever.
Figs. 5, 6 and 7 are enlarged front, side and back view respectively of the cutter
head, showing arrangement of cutters.
Similar letters refer to similar parts in all the figures.
A is the cutter head fitted on spindle a working in bearings bb¹ mounted on
frame such as B or of any other suitable form; fast and loose pulleys c c¹ being
fitted on said spindle a.
This cutter head consists of a flanged wheel the flange of which is bevilled on
the inner side and somewhat rounded on its face; this flanged wheel is provided
with five knives or cutters d d', e and f'f'; the knives or cutters d d' are for
crozing" or grooving the staves of the casks or barrels.
The knife or cutter d has cutting edges which regulate the width of the groove

page_text: while the knife or cutter d' has a cutting face which regulates the depth of said
groove.
The knife or cutter e works in advance of the knives or cutters & d', and is for
"chiving" or levelling the way for said knives or cutters d d¹ in order to insure a
uniform depth of groove.
These knives or cutters d d pass through the face of rim of wheel (or cutter
head) and are secured by a set screw. The knife or cutter e also passes through
face of rim of wbeel (or cutter head) but is held and seated at an opposite or right
angle to the said kuives or cutters d d'.
The two knives or cutters ff' are for the purpose of "chiming" or chamfering
the inside edges of the staves of the casks or barrels, and pass through the
bevilled flange of wheel (or cutter head) to the back of which they are held by set
screws.
C is the cask or barrel which has a grooved metal truss hoop a fitted temporarily
on each end whilst being operated upon. D is the adjustable "cradle" on which
the inner end of cask or barrel rests whilst being operated upon; the lower portion
of this adjustable "cradle" has two sockets which slide upon two pillars i i and
is raised and lowered as desired by means of the lever E working on a fulcrum j
and actuated by the screw which works in a vertical stand F and is fitted with a
wheel; an adjustable screw stop m being fitted near bottom of said stand Fin
order to regulate the distance the lever is required to be lowered.
The upper flanged rib of this cradle has a tongue n on its upper surface,
corresponding with the grooved hoops 9 on end of cask or barrel and on which the
said grooved hoop works when the cask or barrel is turned round; G is the cradle
on which the outer end of cask or barrel C rests.
His the winch to the barrel or drum of which one end of rope o is secured and
coiled, then passed under a friction guide pulley p and then over and round the
cask or barrel C to which it is secured by a hook.
The apparatus is worked as follows:-
The grooved truss hoops g having been fitted on cask or barrel, it is placed on
the cradles D and G the groove of truss hoop at inner end fitting over the tongue n
on top of cradle D.
The book on rope o is then driven into the cask or barrel at about its centre
when the cask or barrel is turned round by hand coiling the rope round its
periphery as shown.
Motion is then conveyed by means of belting to the pulleys c c¹ causing the
cutter head A to rotate in the direction indicated by darts.
The lever E is then depressed by means of the screw k thereby raising the
cradle D and bringing the inner end of the cask or barrel C in contact with the
cutter head A, at the same time the handle of the winch H is turned thereby
coiling upon its barrel or drum the rope o which, by reason of its passing under
the friction guide pulley p, holds down the cask or barrel C to the cradles D
and G, whilst at the same time turning or revolving it in a direction opposite to
that of the cutter head A; the knife or cutter e levelling the staves, the knives or
cutters d d "crozing" or grooving same, while the knives or cutters ff "chime
or chamfer said staves at one operation and at one revolution of the cask or barrel
being operated upon.
"
If desired, a second cutter head with cutters could be attached to opposite end of
spindle a so that two separate casks may be chimed and crozed at one and the
same time.
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. In apparatus for chiming and crozing the staves of casks or barrels, the cutter
head A carrying knives or cutters d, d', e, and ff', substantially as and for the
purposes herein described and illustrated in the annexed drawings.

page_text: 2. The adjustable cradle such as D, with lever E attached and actuated by
screw k, working in a stand such as F, and fitted with adjustable stop m, sub-
tantially as herein set forth.
3. The combination of appliances for holding down and turning the cask or
barrel whilst being operated upon, consisting of the rope o, friction guide pulley
such as p, and winch such as H, substantially as herein set forth.
4. The general arrangement of the apparatus for chiming and crozing the staves
of casks or barrels, as a combination of parts, substantially as herein described and
illustrated in the annexed drawings.
