Improvements in Barrel Making Apparatus.
1, ANDERS GUSTAF WILLIAM BERN of 42, Tudor Road, Hackney, London, N.E.,
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:--
This invention relates to improvements in connection with barrel making
apparatus, and is intended to provide a means by which the barrel may be
completed in an easier and more effective manner than is at present the case.
The special improvement which I provide consists of a table which is adapted
to carry the head of the barrel and to hold it in the position required for closing.
This additional table is carried by the ordinary sliding table on which the
unfinished barrel is placed, and the additional table is adapted to rise with the
ordinary one or independently of it. According to the arrangement I prefer to use,
the table is carried by a central pin, which projects into a cylinder or hollow ram
serving to support the main table.
This supporting spindle itself forms a ram and fits closely into the top of the
cylinder allowing the additional table to be raised and lowered independently of
the main spindle and table. On the main table being raised, pushing the barrel
un to the hooping and closing portion, the upper ends of, the staves will be brought
together and closed against the head lying on the secondary table, the hoops at
the same time being placed on. The closing jaws are secured together when in
their closed position by a special catch, consisting of a lever having a cam-shaped
termination carried by pivoted lugs or arms. On pulling this lever round the
cam will bear against the side of the jaw and on further pushing round the lever
it will jam and hold the parts together.
In order that the invention may be more clearly understood, reference is had
to the accompanying drawings, in which Fig. 1 is a side elevation partly in section
of one form of my improved apparatus, Fig. 2 is a plan of the upper part of the
apparatus, Fig. 3 is a similar view of a slightly modified arrangement, Fig. 4
shows a second modification, and Figs. 5 and 6 are detail views.
Referring to the arrangement shown in Figs. 1 and 2, A is the sliding table
cariying the unfinished barrel B which is placed on top of this sliding table. The
ram C carrying the table A is hollow or of cylindrical form sliding within a
larger cylinder D in the ordinary manner. Through the table and projecting into
the cylindrical plunger C passes a vertical spindle E, to the top of which
the secondary table F is fitted. This spindle forms a ram projecting into the
cylindrical ram C so that on hydraulic or other pressure being employed, the
table F will be slidden up or lowered as required. The cup packing e forms a
tight joint around the spindle, and to prevent the latter rising too far the head e¹
is provided meeting the top of the cylinder C when the table is in its uppermost
position. The table is shown in Fig. 1 in its top position ready for the closing
oneration. The table A is provided with the raised surface a on which the bottom
of the barrel rests, and this is recessed at a¹ so that when the table F is lowered
it will fit closely into this recess forming a level surface. This allows the barrel

page_text: to be removed when completed, and also to be placed in position easily, when the
table F is lowered out of the way. The head or secondary table is fitted to the
spindle in the manner shown in Fig. 6 a screwed pin f being employed screwing
into the hollow head of the spindle. On top of this table the head G is placed so
that it is secured in place as the sides are formed.
To form the barrel and place the hoops in position, the jaws H and H¹ are
employed, the latter being hinged to the former at one side so that it can be turned
round as shown in Fig. 2 into open position or closed as shown in dotted lines in
the same figure. The recesses h are shaped to the form of the top of the barrel
in the ordinary manner and. are provided with the grooves h¹ to receive the hoops.
As shown in detail in Fig. 5, these grooves are provided with the small recess h³
so that the joint of the hoops can fit into this, recess, allowing them to be placed
more smoothly on the barrel.
To secure the jaw H₁ a special form of catch is employed consisting of the
lever J having the cam shaped termination j. This lever is pivoted between the
plates or arms K carried by the side L of the apparatus. On turning this lever
and arm round into the position shown in dotted lines in Fig. 2 the cam will bear
against the end of the jaw H¹ holding it securely in place and completing the
closing and hooping arrangement.
As shown in Fig. 3 instead of the spindle E being movable it is fixed to the
sliding table A screwing into it or being.secured in any other convenient manner.
In this case the height of the apparatus must be somewhat greater than in the
This
other, in order to allow room for the barrel to be placed over the table.
figure also shows the barrel being closed and hooped, and while this process is in
operation the upper hoop or ring M is placed over the end securing the extremities
of the staves in their closed position.
Instead of employing the spindle E a tripod arrangement may be employed
for supporting the table, or any ordinary and well known support may be used for
this purpose.
As shown in Fig. 4 the barrel instead of being carried by the sliding table A
is placed upon a pivoted table N immediately over the sliding table. This table N
is pivoted to the post L at one side the boss n being employed for this purpose.
The table F is carried by this pivoted table or support the spindle E being screwed
into the boss of the support, the arrangement being otherwise similar to that
last described.
Instead of requiring the barrel to be placed over the table F when it is under the
top of the apparatus, the support can be turned round out of the way so as to clear
te remainder of the machine, allowing room for the barrel to be placed in
position without interfering with any other part.
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 an improved barrel making apparatus, the combination with a sliding
table carrying the unfinished barrel, of a secondary table fitted to it and supporting
the head of the barrel in the position required for fixing, substantially as
and for the purposes specified.
(2) In an improved barrel making apparatus, the combination with a sliding
table carrying the unfinished barrel, of a secondary table carried on a vertical
spindle or ram, and a cylindrical ram carrying the main sliding table, and
receiving the ram of the secondary table allowing the latter, to be raised indepen-
dently, substantially as described and for the purposes specified.
(3) In an improved barrel making apparatus, the combination with a sliding
table carrying the finished barrel and a cylindrical ram, supporting the table, of
a secondary table receiving the head of the barrel and carrying it into proper
position for fixing, a spindle or ram supporting the said table, extending into the
cylindrical ram, and a recess in the top of the main table receiving the, secondary

page_text: table when lowered, substantially as described and shown and for the purposes
specified.
(4) In an improved barrel making apparatus, the combination with a sliding
table carrying the unfinished barrel, of a secondary table supporting the head of
the barrel in the proper position for fixing and a spindle to which the said table
is fitted screwed or otherwise fixed to the main table, substantially as described
and shown and for the purposes specified.
(5) In an improved barrel making apparatus, the combination with a sliding
table above the same pivoted to one of the side pillars and adapted to receive the
barrel and a secondary table supporting the head of the barrel in the proper position
for fixing, carried by the hinged support, substantially as described and for the
purposes specified.
(6) In an improved barrel making apparatus the combination with a sliding
table and additional table for the head, of a catch securing the jaws of the upper
part of the apparatus, consisting of a lever having a cam portion, carried by pivoted
arms and locking the jaws together, substantially as described and shown in
Figs. 1 and 2 of the drawings and for the purposes specified.
(7) In an improved barrel making apparatus forming the grooves to receive the
hoops with a recess in which the joints of the hoop fit, substantially as described
and shown in Fig. 5 of the accompanying drawings, and for the purposes specified.
