I FREDERICK MYERS of 17 Ashcroft Buildings Liverpool in the County of
Lancaster, Machine Manufacturor do hereby declare the nature of my snid
invention for "IMPROVEMENTS IN MACHINERY FOR CHAMFERING CROZING AND
TRIMMING BARREL OR CASK STAVES AND IN MEANS FOR REGULATING THE SUPPLY
OF STAVES REQUIRED TO FORM A BARREL OR CASK OF ANY GIVEN DIAMETER," to
be as follows :—
In specification No 419 of 1883 I have described apparatus for the manufacture
of barrels, part of such apparatus being adapted for cutting the staves to the
desired length, bevelling their ends and forming the grooves therein.
My present invention consists not only in improvements on the arrangement of
parts set forth but also in improved combinations and construction of apparatus
by means of which I am able to rapidly and accurately supply the requisite
number of staves to form a barrel or cask of any predetermined size said
staves being taken from the feed and automatically carried forward, chamfered,
crozed, trimmed, and delivered ready for immediate use to form a barrel or cask.
To carry my invention into effect I provide framework with suitable journals
for the reception of the necessary shafts.
The main driving shaft or shaft number one is driven in the usual manner, and
carries two pulleys from the first of which motion is transmitted to the cutter shaft
or shaft number two.
Shaft number two is supplied with right and left hand screw threads upon
which are screw rotary cutter heads the said heads being provided with cutters
or knives ground to any suitable angle to form the desired chamfer to one or both
ends of the staves and being also provided with suitable cutters to form the croze
near one or both ends of the staves and further with circular saws to trim the ends
of the staves and cut them all of a uniform length. The rotary cutter heads are
held in place by jam nuts or set screws and are adjustable to allow staves of various
lengths to be prepared. The second pulley on shaft number one transmits motion
to shaft number three by means of a belt passing around a pulley secured thereon.

page_text: To this said shaft is also fixed a second pulley which transmits motion by means
of a belt to shaft number four to which is secured a wheel suitably constructed to
receive and operate an endless chain which transmits motion to the shaft number
five by means of a corresponding chain wheel thereon. Said shaft number five is
also provided with two similar chain wheels which through endless chains transmit
motion to shaft number six.
The said chains are provided with equidistantly projecting studs and are so
driven that the corresponding studs on each chain keep in line with each other,
thus securing the staves being carried forward and presented to the saws and
rotary cutters at right angles to the same, tho distance between the chains is such
that the shortest and longest staves will be carried forward by the projecting
studs.
The staves may be placed one at a time in front of the projecting studs, but
I prefer to use a suitable hopper capable of receiving a number of staves, and being
formed of two angle pieces to each of which is secured a guide rail for each end of
the staves to rest on while being carried forward by the endless chains. The front
of the angle pieces forming the hopper are formed with an aperturo at the lower
front end to admit of only one stave at a time being removed therefrom, while the
projecting studs on the chains are also only of a height sufficient to catch one stave
-at-a-time which it removes from beneath_the_pile. The anglo pieces forming the
-hopper-and-the-guide-rails-are-adjustable and secured in place by hand_screws_or
bolts, the guide rails are provided with lateral springs to guide the staves properly
to the saws and cutters. One of the guide rails has attached to it an arm which
supports a flexible or spring arm adapted to keep the staves down while being
acted upon by the saws and cutters. I arrange at the front end of the machine a
stationary frame-having-Trails-upon-which-rests-a-moveablo-frame provided on
the underside with flanged or grooved wheels which travel on the said T. rails
enabling the frame to be easily moved from one side to the other The said
frame is divided into two parts or divisions by a centre piece, each division
having suitable rails for the staves to slide on and also with stops or gunges
These guages slide-on measures or rules and may be secured thereto at any desired
point by any suitable means. I will now suppose that a barrel or cask is to be mado
having an inside bulge diameter of 20 inches, therefore the inside circumference
would be about 63 inches, the stop or guages must therefore be set so that the
distance from the face of said guages to the front edge of the moveable frame will
be 63 inches. As each stave is finished it passos on to the frame and as soon as the
frame is filled the attendant quickly moves the frame presenting the empty division
to receive the staves for the next barrel.
As the width of the staves varies considerably I arrange a series of chambers
beneath the moveable frame in which staves of various widths may be kept to
enable the attendant to replace the last stavo with a wider one if the edge of the
same should not reach the front edge of the moveable frame and vice-versa if the
last stave should be narrow, while instead of the horizontally moveable table I may
employ a pivoted table provided with a series of arms which can be charged with
the staves as before described and alternately or consecutively presented to the
front of the machine.

Trimming Barrel or Cask Staves, and in Means for Regu-
lating the Supply of Staves required to Form a Barrel or
Cask of any given Diameter,
I, FREDERICK MYERS of 17 Ashcroft Buildings Liverpool in the County of
Lancaster Machine Manufacturer do hereby declare the nature of my said
invention for IMPROVEMENTS IN MACHINERY FOR CHAMFERING, CROZING AND
TRIMMING BARREL OR CASK STAVES, AND IN MEANS FOR REGULATING THE SUPPLY
OF STAVES REQUIRED TO FORM A BARREL OR CASK OF ANY GIVEN DIAMETER and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
In specification No 419 of 1883 I have described apparatus for the manufacture
of barrels, part of such apparatus being adapted for cutting the staves to the desired
length, bevelling their ends, and forming the grooves thorcin. My present invention
consists not only in improvements on the arrangement of parts set forth, but also in
improved combinations and construction of apparatus by means of which I am
able to rapidly and accurately supply the requisite number of staves to form a
barrel or cask of any predetermined size; said staves being taken from the feed
and automatically carried forward, chamfered, crozed, trimmed and delivered ready
for immediate use to form a barrel or cask.
To clearly explain may invention reference is made to the accompanying drawings
which form part of this specification, and in which, like letters of reference aro
used to designate like parts of the apparatus throughout the various figures of
which
Fig 1. represents a plan view
Fig 2. a side elevation
Fig 3. a front end elevation
Fig 4. a rear elevation of the hopper and
Fig 5. a modification of the form of receiving table.
To carry my invention into effect I provido framework a. with suitable journals
for the reception of the necessary shafts. The main driving shaft a² is provided
with fast and loose pulleys a³ a' and is driven in the usual manner, said shaft also
carries two pulleys as a from the first of which, motion is transmitted to the
cutter shaft b. through a small pulley fixed to said shaft but which is not shewn in
the drawings.
Shaft b is supplied with right and left hand scrow threads upon which screw
rotary cutter heads b', the said heads being provided with cutters or knives o.
ground to any suitable angle to form the desired chamfer to one or both ends of
the staves and being.also provided with suitable cutters c' to form the croze near

page_text: one or both ends of the staves, and further with circular saws to trim the ends
of the staves, and cut them all of an uniform length. The rotary cutter heads b¹
are held in place by jam nuts c³, or set screws and are adjustable to allow staves
of various lengths to be prepared. The small pulley a" on shaft a³ transmits motion
to shaft d. by means of a belt passing around pulley d' secured thereon. To said
shaft d. is also fixed a second pulley d which transmits motion by means of a belt
and pulley d', to shaft d³ to which is secured a wheel d suitably constructed to
receive and operate an endless chain e. which transmits motion to the shaft e¹ by
means of a corresponding chain wheel e thereon. Said shaft e¹ is also provided
with two similar chain wheels ee which through endless chains f. f¹ transmit
motion to shaft g. through wheels f³ƒ³ secured thereto.
The said chains f. f¹ are provided with equidistantly projecting studs gl and are
so driven that the corresponding studs on each chain keep in line with each other,
thus securing the staves being carried forward and presented to the saws and
rotary cutters at right angles to the same the distance between the chains is--such
that the shortest and longest staves will be carried forward by the projecting studs.
The staves may be placed one at a time in front of the projecting studs, but I prefer
to use a suitable hopper capable of receiving a number of staves, and being formed
of two angle pieces hh' to each of which is secured a guide rail h³ ³ for each end.
of the staves to rest on while being carried forward-by-the-endless-chains.
The front of the angle pieces forming the hopper are formed with an aperturo at
the lower front end to admit of only one stave at a time being removed therefrom,
while the projecting studs g¹ on the chains are also only of a height sufficient to
catch one stave at a time which it removes from beneath the pile.
The-angle-pieces-forming the hopper and the guide rails are adjustable and
secured in place by hand screws or bolts k, the guide rails are provided with lateral
springs to guide the staves properly to the saws and cutters. The guide rail /?
has attached to it an arm which supports a flexible or spring arm ³ adapted to
keep the staves down while being acted-upon-by-the saws-and-cutters-I-arrango
at the front end of the machine a stationary frame having rails m' m² upon which
rests a moveable frame.n provided on the underside with flanged or grooved wheels
which travel on the said rails, enabling the frame to be easily moved from one sido
to the other. The said frame is divided into two parts or divisions by a centre
piece o each division having suitable rails o' for the staves to slide on, and is also
provided with stops or guages o³ o³. These guages slide on measures or rules p
and may be secured thereto at any desired point by thumb screws or by other
suitable means. I will now suppose that a barrel or cask is to be made having
an inside bulge diameter of 20 inches therefore the inside circumference would be
about 63 inches, the stop or guages must therefore be set so that the distanco from
the face of said guages to the front edge of the moveable frame will be 63 inches.
As each stave is finished it passes on to the frame and as soon as the frame is
filled about as shown in Fig 1. the attendant quickly moves the frame presenting
the empty division to receive the staves for the next barrel.
As the width of the staves varies considerably I arrange a series of chambers
numbered 1 to 8 beneath the moveable frame in which staves of various widths
may be kept to enable the attendant to replace the last stave with a wider one if
the edge of the same should not reach the front edge of the moveable frame, and
vice versa if the last stave should be narrow while instead of the horizontally
moveable table I may employ a pivoted table as represented in Fig 5 provided
with a series of arms which can be charged with the staves as before described
and alternately or consecutively presented to the front of the machine. Before
being manufactured into barrels staves are sometimes trimmed to an uniform length,
but chamfering, crozing (and generally trimming) are usually done after the barrel
is formed while in such manufacture difficulty frequently arises in securing without
waste, the selection and use of exactly the number and diameter of staves required
for the construction of a barrel of any predetermined diameter.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
The improvements in and combination of machinery or apparatus for chamfering,
crozing and trimming Barrel or cask staves, and the incans for regulating the
supply of staves required to form a barrel or cask of any predetermined diameter
substantially as specified.
