PROVISIONAL SPECIFICATION left by the said Philip Middleton Justice at

PHILIP MIDDLETON JUSTICE of 55 & 56 Chancery Lane in the County of
Middlesex Fellow of the Institute of Patent Agents "IMPROVEMENTS IN BARREL
FORMING MACHINES" a communication to me from abroad by Frederick Myers
temporarily residing at Hamburg Germany
In this improved Barrel forming machine the discs whereon the staves are
arranged in the barrel form to receive the truss hoops do not turn around with the
staves as is generally the case in other machines but are stationary and have a
groove into which the staves are pushed through a notch in the outer rim of the
groove and the staves are pushed around in the grooves to make the form. Prior
to entering the grooves the staves are pushed over a bulging device that causes the
required outward bend at the middle for the bulge of the barrel From the bulger
the staves pass over a ring located midway between the holding discs that press the
staves outward and maintains them in the bulged shape the ends of the staves
being confined by the outer rims of the grooves in the discs This ring is connected
to a support, which when about two thirds of the barrel form is placed around the
ring is made to automatically release the ring, the ring is then retained by the staves
already on, and spring between it and the flanges of the disce until the rest of the
staves are pushed on, and the barrel form is completed The truss hoops are then
forced on the barrel form, and the ends of the staves are sprung inward against or
towards the inner walls of the grooves of the discs thus enabling the staves to be
trussed tightly at the ends One of the discs is then (after the truss hoop carriers
retire) drawn back to discharge the formed barrel, and the barrel takes the inside

page_text: forming ring with it The ring is made collapsible and is then collapsed by the
attendant reaching into it from one end of the barrel form and returned to its
place in the machine preparatory to another operation In practice the rings will
be used with one machine, so that one can be put in the machine, as soon as the
barrel form containing the other ring is discharged These are the essential
features of the machine but it also comprises other devices of detail as will be
hereinafter described. The discs on which the staves are to be received and
arranged in barrel form and held until the truss hoops are applied are like other
forming and retaining discs arranged on axial supports a suitable distance apart
to receive the staves between them by the ends of the staves. These discs which
have beretofore been arranged to turn on their axial supports as the staves are
supplied to them, I now propose to arrange stationary, and construct them with a
groove in the face with a notch through the outer rim of the groove, through
which the staves are to be pushed into the groove one after another, the staves in
the groove being pushed around successively until the form is complete by the
entering of the staves The staves are to be pushed into the grooves of the forming
discs through grooved guides for the ends of the stave by a pusher or feeder from
the feeding table whereon the staves are to be supplied in front of said pusher by
any approved means.
The means that I prefer and propose to employ consist of a bench located over
the feeding table and adapted to receive and hold the pile forming the complement
of staves for one barrel together with end and edge guides to guide the fall of the
Staves from the bench on to the table, the staves being dropped one by one from
the pile by the attendant upon the table or the pusher as they may happen to fall.
In case they fall on the pusher, posts will hold them when the pusher goes back
enabling the pusher to escape and let them fall on the table in front of the pusher
the length of the pusher is such, that the staves will not fall behind the pusher
when it goes forward The end and edge guides consist of angle plates which
are adjustably bolted to the top of the table by brackets and the side plates having
the grooves, through which the staves are pushed into the discs are bolted to the
end guides the edge guides terminate sufficiently above the table to allow the ends
of the staves to pass under them into the grooves At the edge of the table over
which the staves are delivered to the forming discs and at the middle of the spaces
between the discs I arrange a bulger and also friction rollers on each side of the
bulger, the bulger consists of a metal rib rising up from the plane of the table and
having a curved back over which the staves are to be forced for bulging them up
in the middle, the ends being held down in the guide grooves The pusher is
pivoted to the side which drives it and lays on the table so that it may rise up on
the bulger to continue its bearing against the edge of the staves and push them
beyond the bulger into the discs When the staves enter the grooves at their ends
they pass off from the bulger at their middle and onto a ring located midway
between the discs and being to hold the staves out in the bulged form by pressing
them at the ends against the outer rim of the groove thus keeping the staves in
the bulged form without end pressure of the discs on the staves and enabling the
staves to be pushed around easily in the grooves of the discs
This ring is supported on the end of a strong bar which enters a socket in the
ring, said bar being arranged to slide forward and backward in a suitable support
in the machine and is secured in the holding position by a latch pivoted to a fixed
support and dropping behind a shoulder or ledge of the bar The latch has an
arm projecting beyond the periphery of the ring and downward, sufficiently below
the bar to be touched by the end of the first stave of the barrel form when the
form has been pushed around about two thirds of the course and be raised by the
said stave so that the latch will escape from the ledge of the bar, a spring attached
to a lever connected with the sliding bar will then instantly draw the supporting
bar of the ring back out of the ring and away from the course of the staves
allowing the ring to be held solely by the staves which then enclose about two thirds
of the circumference of the ring and hold it sufficiently for the rest of the staves

page_text: to be delivered on it, the ring then being carried by the staves and being enclosed
by them so that it retains them in the bulged form without other support The
lever may be worked by hand to pull back the bar if preferred and in that case the
latch may not be required. When the barrel form is completed the ring will
be wholly enclosed in said form and will remain in the form until the truss
hoops are put on and the form is discharged from the machine. The ring
consists of two half circular parts that are pivoted to a socket head and are
held in position by the jointed spokes and a second lever by which it is
collapsed, when the ring is to be removed from the trussed barrel form after the
latter has been discharged from the machine By the use of this bulge ring and
the outer rims of the grooved discs for holding the staves it will be seen that they
may be held without end pressure of the discs on them and also without any
supporting rim or flange under or without the ends of the staves. I therefore
make the inner rims of the grooves of the forming discs considerably smaller than
the inner circumference of the form of barrel staves before the truss hoops are put
on, and may dispense with said rims altogether in order that the staves may be
contracted by the truss hoops until the edges of the staves are firmly closed
together, which cannot be well done when the staves are firmly bound at the
ends between the discs nor at all when they are formed and rest on an inner
flange But it is desirable to have the ends of the staves touch the bottoms
of the grooves in the discs when they enter said grooves to keep the staves
even with each other and it is also desirable to have them continue to touch
when the staves are contracted by the truss hoops I therefore form the bottom
of the grooves in a bevel shape of about the angle or curve that the ends of
the staves will describe when closed in by the truss hoops
The guides have to shift out of the way of the truss hoop carriers when the
barrel form is completed to allow said carriers to move forward and apply the truss
hoops and it is also desirable that the guides be enabled to rise a little, when the
last stave has been pushed in and the first one has returned to the upper side
under the guides so that the stave will not be bound by the guides, the plates
having the guide grooves are therefore attached to the table and the table is pivoted
to the supporting frame enabling the guides to be raised by the staves any time it
may be required. The guides and table are connected by rods with the arm of a
rock shaft which is connected by another arm and a rod with a lever that is
arranged with a cam on a shaft which operates the truss hoop carriers so that the
guides and table will be raised automatically clear of said carriers just before they
advance. These truss hoop carriers are mounted on the slide ways and the one next
to the shaft is connected to it by rods and eccentrics and the other is connected to
said shaft by the rods and the crank pins, the crank pins and the eccentrics being
relatively arranged to move said truss hoop carriers in opposite directions when the
truss hoops are thus applied to the barrel form, the latter is discharged from the
machine by pulling a disc at the right hand end of the machine back by a hand
lever mounted on a fulcrum and connected to the centre shaft or stud of the disc.
A dog locks the lever for holding the disc in the working position To raise the
table and guides up by hand when it may be required to do so and to hold it up
in case it may be required to adjust any misplaced staves. I have arranged a hand
lever on a fulcrum pivot with the end of the short arm reaching under a rod and
the other end projecting from the machine at the back suitably for being worked
to raise and lower the table and guides at will, a catch pawl is pivoted to the lever
for holding the table up by hooking into a notch of the frame.
I sometimes arrange adjusting screws under the feed table and in part of the
frame to which the table is pivoted, by which it regulates the position of the table
with relation to the disc, but they may be used or not as preferred. The pusher is
connected to a rock lever having a fulcrum and connected by a rod with the crank
pin of a wheel on the centre stud to which motion is imparted by a pinion of a
shaft that gears with the driving shaft which is provided with suitable gear. The
pinion shaft has continuous motion and the pinion is connected to said shaft by a

page_text: clutch having a hand lever for enabling the operator to start and stop the pusher
as required The pusher is to be stopped when a barrel form is completed although
it may run without harm when the table is held up by lever and there are no staves
supplied to the pusher and it is to be started again ready for making another form
The truss hoop driving shaft is to make only one revolution at each operation, the
driving wheel by which it is turned and is therefore fitted loosely on said shaft to
turn continuously and is provided with a number of clutch studs projecting from
one side of its hub to be engaged by a gib when the carriers are to be set in motion,
the gib slides in a groove of the shaft and a collar thereon and is shifted forward
into connection with the studs by a spring for starting the truss hoop carriers The
gib is withdrawn to stop the carriers, and is held in check to let the carriers rest
by a trip lever which has an incline that the head of the gib runs against when the
trip lever is let fall for the purpose and draws the gib back free of the clutch studs.
To start the truss hoop carriers, the trip lever is to be lifted above the head to
allow the spring to act, it may be lifted by a handle but for enabling the attendant
to raise it from his position in front of the machine a foot lever is arranged with
said trip lever and extended to the front of the machine. I propose to use rubber
or other elastic cushioning rings in the truss hoop carriers behind the truss hoops
for yielding to the resistance of the truss hoops when necessary
And to prevent
any of the staves from springing up too high by the bulger and the bulging ring
and prevent the edges of wide staves from overlapping the edges of narrow ones, as
they naturally will in consequence of their tangential extensions from the point of
contact on the bulging boop, I will have a spring presser located in suitable
relations with said bulger and ring to press down any such projecting edges, the
spring may be supported on a strong curved bar attached to the frame and suitably
extending up over the bulger and ring the spring may be provided with adjusting
screws to regulate its tension

PHILIP MIDDLETON JUSTICE of 55 & 56 Chancery Lane in the County of
Middlesex, Fellow of the Institute of Patent Agents IMPROVEMENTS IN BARREL
FORMING MACHINES, a communication to me from abroad by, Frederick Myers
temporarily residing at Hamburg, Germany.
In this improved barrel forming machine the discs whereon the staves are
arranged in the barrel form to receive the truss hoops do not turn around with the
staves as is generally the case in other machines but are stationary and have a
groove into which the staves are pushed through a notch in the outer rim of the
groove and the staves are pushed around in the grooves to make the form. Prior
to entering the grooves the staves are pushed over a bulging device that causes the
required outward bend at the middle for the bulge of the barrel. From the bulger,
the staves pass over a ring located midway between the holding discs that press
the staves outward and maintains them in the bulge shape, the ends of the staves
being confined by the outer rims of the grooves in the discs. This ring is connected
to a support which when about two thirds of the barrel form is placed around the
ring is made to automatically release the ring, the ring is then retained by the
staves already on and spring between it and the flanges of the discs until the rest
of the staves are pushed on and the barrel form is completed.
The truss hoops are then forced on the barrel form and the ends of the staves
are sprung inward against or towards the inner walls of the grooves of the discs,
thus enabling the barrel form to be trussed tightly One of the discs is then drawn
back, after the truss hoop carriers retire, to discharge the formed barrel, taking the
inside forming ring with it. The ring is made collapsible and is then collapsed by
the attendant reaching into the barrel form, and returned to its place in the machine
preparatory to another operation. In practice, two or more rings will be used with
one machine so that one can be put in the machine as soon as the barrel form
containing another ring is discharged. These are the essential features of the
machine but it also comprises other devices of detail as will be hereinafter fully
described, reference being made to the accompanying drawings in which:---
Fig 1. is a front side elevation of my improved barrel forming machine
Fig 2. is an end elevation looking at the left hand side
Fig 3. is a transverse sectional elevation on line × × of fig 1 and looking towards
the right hand.
Fig 4. is a plan view of the principal portion of the machine with some parts in
horizontal section.
Fig 5. is also a plan view of the principal portion of the machine with some parts
in horizontal section.
Fig 6. is a detail showing the bulging ring in side elevation with part of a barrel
form on it in section together with the apparatus by which the ring is mounted in
the machine, and
Fig 7. is a side elevation of the bulging ring as when collapsed for removal from
the barrel form.
The discs "a" on which the staves are to be received and arranged in barrel form
and held until the truss hoops are applied are like other forming and retaining discs,
arranged on axial supports "b," a suitable distance apart to receive the staves
between them by the ends of the staves. Their discs which have heretofore been
arranged to turn on their axial supports as the staves are supplied to them. I now

propose to arrange stationary and construct them with a groove "c" in the face
with a notch "d" through the outer rim "e" of the groove, through which the
staves enter when pushed into the groove, one after another, the staves which have
entered the groove being pushed around successively until the form is completed by
the entering of the staves. The staves are to be pushed into the grooves of the
forming discs through grooved guides "2" for the ends of the staves by a pusher "f"
or feeder from the feeding table "g" whereon the staves are to be supplied
in front of said pusher by any approved means. The means that I prefer and
propose to employ consist of a bench "h" located over the feeding table and
adapted to receive and hold the pile forming the complement of staves for one barrel
together with end guides "i" and edge guides "j" to guide the fall of the staves
from the bench on to the table, the staves being dropped one by one from the pile
by the attendant. upon the table or the pusher as they may happen to fall. In
case they fall on the pusher the stationary stops "k" will hold them when the
pusher goes back enabling the pusher to escape and let them fall on the table in
front of the pusher. The length of the pusher is such that the staves will not fall
behind the pusher when it goes forward. The end guide "i" and edge guide "j
consist of angle plates which are adjustably bolted to the top of the table "g" by
slotted lugs 83 the side plates "13" having the grooves "" through which the
staves are pushed into the discs are bolted to the edge guide "j" fig 3, the edge guides
terminate sufficiently above the table to allow the ends of the staves to pass under
them into the grooves "j" see figs 1 and 3. At the edge of the table "g" over
which the staves are delivered to the forming discs and at the middle of the spaces
between the discs I arrange a bulger "" also friction rollers "13" each side of the
bulger, the bulger consists of a metal rib rising up from the plane of the table and
having a curved back over which the staves are to be forced for bulging them up
in the middle, the ends being held down in the guide grooves "". The pusher
is pivoted at "m to the slide "n" which drives it, and lays on the table "g"
that the forward end will raise up with the stave while the same is being bulged
and continue its bearing against the edge of the stave and push it beyond the
bulger into the discs. When the staves enter the grooves "c" at their ends, they
pass off from the bulger at their middle and on to a ring "o" located midway
between the discs to hold the staves out in the bulged form by pressing them at
the ends against the outer rim "e" of the groove thus keeping the staves in the
bulged form without end pressure against the discs, enabling the staves to be
pushed around easily in the grooves of the discs. This ring "o is supported on
the end of a bar "p" which enters a socket in the ring at "q" said bar being
arranged to slide forward and backward in a suitable support "" in the
machine, and is secured in the holding position by a latch "8" pivoted to the fixed
support and droping behind a shoulder or ledge "t" of the bar "p". The
latch has an arm 66 "
น projecting beyond the periphery of the ring and downward
sufficiently below the bar to be touched by the edge of the first stave "m³" of the
barrel form, when the form has been pushed around about two thirds of the course
and is raised by the said stave so that the latch will escape from the ledge "t" of
the bar "p", a spring "v" attached to lever "w connected with the sliding
bar "p" will then instantly draw the supporting bar of the ring back out of the
ring and away from the course of the staves; the ring then being held solely by the
staves, which theu enclose about two thirds of the circumference of the ring and
hold it sufficiently for the rest of the staves to be delivered on it the ring being
carried by the staves and being enclosed by them, retaining the same in the bulged
form without other support. When the barrel form is completed the ring will be
wholly enclosed in said form and will remain there until the truss hoops are put
on and the form is discharged from the machine. The ring consists of two half
circular parts that are pivoted to socket head "q" at "x" and are held in position
by jointed arms "y" and a second lever "" by which it is collapsed, when the
ring is to be removed from the trussed barrel form after the latter has been
discharged from the machine By the use of this bulge ring and the outer

page_text: t
rims " e " of the grooved discs for holding the staves it will be seen that
they may be held without end pressure of the discs on them and also
without any supporting rim or flange under the end of the staves; I therefore
make the inner rims "a1" of the grooves "c" of the forming discs, considerably
smaller than the inner circumference of the form of barrel staves before the truss
hoops are put on and may dispense with said rims altogether, in order that the
staves may be contracted by the truss hoops, until the edge of the staves are
firmly closed together, which cannot be well done when the staves are firmly bound
at the ends between the discs, nor at all when they are formed and rest on an
inner flange. But it is desirable to have the end of the staves touch the bottoms
of the grooves in the discs when they enter said grooves to keep the staves even
with each other, and it is also desirable to have them continue to touch when the
staves are contracted by the truss hoops. I therefore form the bottom of the
grooves in a bevel shape, of about the angle or curve that the ends of the staves
will describe when closed in by the truss hoops, see fig 5. The guides "j" have to
lift out of the way of the truss hoop carrier "6" when the barrel form is
completed, to allow said carriers to move forward and apply the truss hoops "p3"
fig 4, and it is also desirable that the guides be enabled to raise a little when, the
last stave is being pushed in, and the first one has returned to the upper side,
under the guides, so that the stave will not be bound by the guides; the plates "ts"
having the guide groove "j" are therefore attached to the table, and the rear end
of the table is pivoted to the supporting frame at "c" enabling the guides to be
raised by the staves any time it may be required. The guides and table are
connected by rods "d¹" and "e" with the arm of a rock shaft "f1" which is
connected by another arm and a rod "q" with a lever "h¹" which is operated by
a cam ""on the shaft "j" which operates the truss hoop carriers "6" so that
the guides and table will be raised automatically clear of the said carriers just
before they advance and remain elevated until let down by the attendant allowing
the barrel form to be freely discharged from the machine and truss hoops placed on
the discs. To hold the table up until this is accomplished I employ a lever "pl"
pivoted at "q" to a standard "q" with one end connected to the rod "d" on the
table, and the other end projecting from the machine at the back having a handle
"84"; near the handle is pivoted a catch pawl "81" which hooks into a notch "f"
of the standard when the table is raised to its extreme height either by the
machine or by hand. The truss hoop carriers are mounted and slide on V shaped
ways "k" The one near the shaft "11" being connected to eccentrics "m""
which are rotated by shaft "j1" and the other is connected to said shaft by the
rods "n" and the crank pins "o"; the cranks pins and the eccentrics being
relatively arranged to move said truss hoop carriers in opposite directions when
the truss hoops are thus applied to the barrel form, the latter is discharged from
the machine by pulling the disc "a" of the right hand end of the machine back
by a hand lever "" mounted on a fulcrum "12" and connected to the centre
shaft or stud "m" of the disc. A dog "n" locks the lever "2" holding the disc
in the working position. I arrange adjusting screws "n" under the feed
table "g" and in the part of the frame to which the table is pivoted, by which to
regulate the angle of the table with relation to the discs "a" but they may be
used or not as preferred. The pusher "f" is connected to a rock lever "u"
having a fulcrum at "l" and connected by a rod "w" with the crank pin x¹
of a wheel "y" revolving on a centre stud to which motion is imparted by a
pinion "a" on a shaft "62" which gears with the driving shaft "c" on which the
driving pulley "d" is fitted to apply the power to the machine, and which drives
the truss hoop carrier shaft "j" by the pinion "e" and wheel "f" see fig 3.
The shaft "b" has continuous motion derived from the main driving shaft "c" by
a bevel wheel "63" fixed to said shaft, which engages with a bevel wheel "b"
fixed to shaft "b" this shaft also has a loose fitting pinion "a" having on one side
a clutch "g" which engages with a sliding clutch "g" operated by a hand lever "h2"
enabling the attendant to start and stop the pusher at will. The pusher is to be stopped

page_text: when a barrel form is completed although it may work without harm when the table
is held up by lever "p1" and there are no staves supplied to the pusher and it is to
be started again ready for making another barrel form. The truss hoop driving
shaft "is to make only one revolution at each operation the driving wheel "f2"
by which it is turned is therefore fitted loosley on said shaft to turn continuously
and is provided with a number of clutch studs "o" projecting from one side of
its hub to be engaged by a gib "p" when the carriers are to be set in motion, the
gib slides in a groove "q" of the shaft, and a collar "g" thereon and is shifted
forward into connection with the studs by a spring "t" for starting the truss hoop
carriers. The gib is withdrawn to stop the carriers and held in check to let the
carriers rest by a trip lever "u" which has an incline "2" that the head "w" of
the gib runs against when the trip lever is let fall for the purpose, and draws the
gib back free of the clutch studs "o² ". To start the truss hoop carriers the trip
lever "u" is to be lifted above head, "w" to allow the spring to act, it may be
lifted by a handle "x2" but for enabling the attendant to raise it from his position
in front of the machine, a foot lever "y" is arranged with said trip lever and
extended to the front of the machine as shown to be worked by the foot of the
operator at "22". I propose to use rubber or other elastic cushioning rings q³ Fig 3
& 4 in the truss hoop carriers behind the truss hoops for yielding to the resistance
of the truss hoops when necessary. It has been found in practice that staves
which have been chimed and crozed beforehand will not bear the necessary end
pressure to be held in the bulged condition by the friction of the pressure of
plain retaining discs on the ends, nor by points of said discs projecting into the
ends of the staves especially in the case of strong rigid staves for heavy barrels ;
but that the ends will crush and split and be materially damaged by such pressure,
and at the best the bulge of some staves will be higher than others, and are liable
to slip out of place without more positive means of holding them. It will there-
fore be seen that the contrivance of stationary grooved discs having a notch in the
outer rim to receive the staves into the grooves to be pushed around therein
affords a simple and efficient means of holding the bulged staves without any
pressure on the ends and in such positive manner that none can escape and it is to
be understood that the stationary condition of the discs is essential to the rise of
the outer flange or rim of the groove. In so far as the feeding and bulging
mechanism retaining disc and truss hoop mechanism for this application are
represented in a prior application filed by my communicator on January 25th 1883
