Improvements in Rotary Moulding Machines for Shaping Metal
Sheets.
We, EDWARD JORDAN, Plumber and Metal Worker, and GEORGE THOMAS
ROGERS, Plumber, both of No. 322, Elizabeth Street, Sydney, in the Colony of
New South Wales, Australia, do hereby declare the nature of this invention
to be as follows:-
The object of this invention is to convert flat sheets of metal into various forms
to render them adaptable to a variety of useful purposes such as mouldings, cor-
nices, O.. and half-round guttering and the like. It is likewise serviceable
to perform certain operations known as beading and wiring.
In the one machine it is sought to combine several useful operations so as
to produce the results above stated, and further by the adaptation of interchange-
able parts to the moulding devices varying results are to be obtained in accord-
ance with the desired dimensions of the articles to be shaped, and such variations
are to a large extent almost unlimited in the range of construction. To accom-
plish these advantages the machine is constructed upon the rotary principle and
the parts thereof used for moulding and shaping the metal sheets are caused to
either wholly or partly revolve in their bearings such movement being deter-
mined by the character and dimensions of the design or series of designs which
it may be desired to produce.
It may be operated by any suitable power and its action can be made either
intermittent or continuous.
The invention is illustrated by the accompanying drawings in which similar
letters are used in connection with the various figures to indicate similar parts
and in which:-
Figure 1 is a side elevation of a rotary moulding machine, adapted to pro-
duce by partial and reverse revolutions two forms of moulded articles and service-
able for performing beading operations.
Figure 2 is an elevation of one end of Figure 1 shewing gearing used for
driving the machine.
Figure 3 is an elevation of the other end of Figure 1 shewing equal gear
wheels and balance weight attached to the rotary moulding dies.
Figure 4 is an elevation of part of a standard with gearing removed to show
movable bearing and compensating spring for same.
Figure 5 is a detail of a detachable moulding strip adapted to form slit or
recess to receive the metal sheets and to form the bead of 0.G. guttering.
Figure 6 is a detail of a detachable and interchangable strip serviceable to
produce O.G. guttering of various dimensions.
Figure 7 is a sectional detail of a pair of rotary moulding dies, suitable for
shaping O.G. guttering and beading and illustrating the progress of the mould-
ing operation.

Figure 11 is a sectional detail of rotary moulding dies similar to Figures

of forms of rotary moulding dies.
Figure 12 is a section of a moulding produced by the removable dies as shewn
on Figures 11 and 13.
Figure 13 is a sectional detail of rotary moulding dies which may be adapted
to a machine designed to produce complete and continuous revolutions.
The general construction and manner of operating the machine and shaping
the metal sheets is as follows;-
The side frames A secured by the tie bolts B, are provided with the V shaped
gaps C, to receive the bottom bearings 1, and upper movable bearings E in
which the journals F and G respectively revolve, such journals forming part
of the bottom rotary moulding dies H and the top moulding dies I. The spur
wheels J keyed to the journal ends are equally geared so as to actuate the rotary
dies II and I at the same speed.
The bottom bearings D are seated as shewn in Figure 4, while the upper
bearings are held by the springs K, which are kept in position by the standard
caps secured by the bolts M to be adjusted as required, the springs are
needful to keep the convoluted surfaces of the rotary dies in contact with each
other when in motion and to prevent jarring, at the same time accomodating
the dies to the thickness of the metal sheets and ensuring the requisite gripping
or biting action which is essential to the production of moulded article.
To the rotary die I (which is peculiarly shaped for the special purposes in-
dicated) the lever N is attached carrying the adjustable balance weight
secured by the bolt P, this weight ensures the easy working of the die I and
produce regularity of action.
The outer standard Q together with one of the standards A are provided with
bearings to support the shaft R carrying the pinion $ and handle T for manual
power, and also the counter shaft U, carrying the spur wheel V and pinion W
shewn dotted in Figure 2, these together with the beforementioned equally
geared wheels J constitute the gearing for operating the machine; but the
method of operating may be varied according to circumstances, and the power
available for driving, such power may be either steam, hydraulic or other suit-
able power. One form of gearing which may be considered particularly appli-
cable to produce the semi-rotary movement, would consist of a double toothed
rack and pinion movement operating reciprocally in the same manner as a steam
or hydraulic piston.
When using the machine to make 0.G. guttering, the rotary dies Hand I are
made as shewn in Figures 7, 8 and 11. Upon the bottom die H, the bead
moulding strip (which is made detachable) is secured in position with screws,
and to provide for the insertion of the metal sheet i, the slit or recess Y is con-
structed, such a recess is also used for other forms of mouldings.
The convoluted surfaces of the dies are made to correspond in dimension to
the size of the article to be shaped hence the enlarging and reducing strips Z
are made interchangeable and may be transformed from the positions shewn on
die H to the horns a on the die I..
In Figure 7 the metal sheet i is shewn folded round the bead X, and assum-
ing the desired shape, as the convoluted surfaces of the dies are brought into
contact with each other, the movement continues in the direction indicated by

page_text: the arrows, until the horn is brought into contact with its corresponding part,
when the moulding operation is completed and the machine is stopped.
In Figure 8 the dies are shewn moving in the reverse direction to Figure 7,
the completed moulded article being ready for removal, and another sheet is
shewn in position on the opposite side ready for moulding. It is to be observed
that the peculiar feature of the invention consists in first securing the sheet of
metal and then winding it gradually round and pressing it into the peculiar
shape of the block mould.
The rounded surface 6 of the die H is provided with the rounded channels c
which when used in combination with the surface d of the die I serve to pro-
duce a beaded sheet by pressing a rod of any suitable diameter into the metal
and curling it as shewn in Figure 10.
In Figure 11 the beading parts are omitted and another form of moulding
substituted and in producing which the operation already described for pro-
ducing 0.G. guttering is repeated--and similar results are obtained.
In Figure 13 the shape of the rotary die is altered so as to produce a number
of blank surfaces e on which a number of moulding devices f and g may be
secured and because of the omission of the horns a, the motion of the dies H
and I may be made continuous instead of intermittent.

Improvements in Rotary Moulding Machines for Shaping Metal
Sheets.
We, EDWARD JORDAN, Plumber and Metal Worker, and GEORGE THOMAS
ROGERS, Plumber, both of No. 322, Elizabeth Street, Sydney, in the Colony of
New South Wales, Australia, 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:
1
The object of this invention is to convert flat shoes of metal into various forms
to render them adaptable to a variety of useful purposes such as mouldings, cor-
nices, O.G. and half-round guttering and the like. It is likewise serviceable
to perform certain operations known as beading and wiring.
In one machine it is sought to combine several useful operations so as to
produce the results above stated, and further by the adaptation of interchange-
able parts to the moulding devices varying results are to be obtained in accord-
ance with the desired dimensions of the articles to be shaped, and such variations
are to a large extent almost unlimited in the range of construction. To accom-
plish these advantages the machine is constructed upon the rotary principle and
the parts thereof used for moulding and shaping the metal sheets are caused to
either wholly or partly revolve in their bearings such movement being deter-
mined by the character and dimensions of the design or series of designs which
it may be desired to produce.
It may be operated by any suitable power and its action can be made either
intermittent or continuous.
The invention is illustrated by the drawings left with our Provisional Specifi-

page_text: cation, and in which similar letters are used in connection with the various
figures to indicate similar parts, and in which :-
Figure 1 is a side elevation of a rotary moulding machine, adapted to pro-
duce by partial and reverse revolutions two forms of moulded articles and service-
able for performing beading operations.

Figure 8 is a section similar to Figure 7 shewing partial revolution of the
moulding dies and one size of O.G. guttering completed-also a sheet of metal
in position to be moulded during the return movement of the dies so as to pro-
duce another size of guttering.
Figure 9 is a section of O.G. guttering as shaped by the rotary moulding dies
shewn in Figures 7 and 8.
Figure 10 is a section of metal sheet with heading as produced by beading
device attached to the moulding dies.
Figure 11 is a sectional detail of rotary moulding dies similar to Figures 7
and 8, but with beading parts omitted and surface fitted to receive a variety
of forms of rotary moulding dies.
Figure 12 is a section of a moulding produced by the removable dies as shewn
on Figures 11 and 13.
Figure 13 is a sectional detail of rotary moulding dies which may be adapted
to a machine designed to produce complete and continuous revolutions.
The general construction and manner of operating the machine and shaping
the metal sheets is as follows:-
The side frames A secured by the tie bolts B, are provided with the U shaped
gaps C, to receive the bottom bearings D, and upper movable bearings E in
which the journals F and G respectively revolve, such journals forming part
of the bottom rotary moulding dies H and the top moulding dies I. The spur
wheels keyed to the journal ends are equally geared so as to actuate the rotary
dies H and I at the same speed.
The bottom bearings D are seated as shewn in Figure 4, while the upper
bearings are held by the springs K, which are kept in position by the standard
caps L secured by the bolts M to be adjusted as required, the springs are
needful to keep the convoluted surfaces of the rotary dies in contact with each
other when in motion and to prevent jarring, at the same time accommodating
the dies to the thickness of the metal sheets and ensuring the requisite gripping
or biting action which is essential to the production of moulded article.
To the rotary die I (which is peculiarly shaped for the special purposes in-
dicated the lever N is attached carrying the adjustable balance weight 0
secured by the bolt P, this weight ensures the easy working of the die I and
produce regularity of action.
The outer standard Q together with one of the standards A are provided with
bearings to support the shaft R carrying the pinion S and handle T for manua!
power, and also the counter shaft U, carrying the spur wheel V and pinion W
shewn dotted in Figure 2, these together with the beforementioned equally
geared wheels J constitute the gearing for operating the machine; but the

page_text: method of operating may be varied according to circumstances, and the power
available for driving, such power may be either steam, hydraulic or other suit-
able power. One form of gearing which may be considered particularly appli-
cable to produce the semi-rotary movement, would consist of a double toothed
rack and pinion movement operating reciprocally in the same manner as a steam
or hydraulic piston.
When using the machine to make O.G. guttering, the rotary dies H and I are
made as shewn in Figures 7, 8 and 11. Upon the bottom die H, the bead
moulding strip (which is made detachable) is secured in position with screws,
and to provide for the insertion of the metal sheet i, the slot or recess Y is con-
structed, such a recess is also used for other forms of mouldings.
The convoluted surfaces of the dies are made to correspond in diameter to
the size of the article to be shaped hence the enlarging and reducing strips Z
are made interchangeable and may be transformed from the positions shewn on
die H to the horns a on the die I.
In Figure 7 the metal sheet i is shown folded round the head X, and assum-
ing the desired shape, as the convoluted surfaces of the dies are brought into
contact with each other, the movement continues in the direction indicated by
the arrows, until the horn a is brought into contact with its corresponding part,
when the moulding operation is completed and the machine is stopped.
In Figure 8 the dies are shewn moving in the reverse direction to Figure 7,
the completed moulded article being ready for removal, and another sheet is
shewn in position on the opposite side ready for moulding. It is to be observed
that the peculiar feature of the invention consists in first securing the sheet of
metal and then winding it gradually round and pressing it into the peculiar
shape of the block mould.
The rounded surface 6 of the die H is provided with the rounded channels c
which when used in combination with the surface d of the die I serve to produce
a wired sheet by pressing a rod of any suitable diameter into a previously par-
tially formed bead in the edge of the metal and curling it as shewn in Figure 10.
In Fig. 11 the beading parts are omitted and another form of moulding sub.
stituted and in producing which the operation already described for producing
O.G. guttering is repeated--and similar results are obtained.
In Figure 13 the shape of the rotary die is altered so as to produce a number
of blank surfaces e on which a number of moulding devices f and may be
secured and because of the omission of the horns a, the motion of the dies H
and I may be made continuous instead of intermittent.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
