An Improved Machine for Moulding or Shaping Guttering and
other similar Articles.
1, ROBERT EDWARD EVENDEN, of "Heaton," North Coburg, in the Colony
of Victoria, Engineer, at present residing at London, in England, do hereby
declare the nature of this invention, to be as follows:-
This invention consists of an improved machine for moulding or shaping
guttering and other similar articles from sheet metal plates. It consists of a
horizontally arranged block and die of the requisite length and of the sectional'
shape or form which the guttering or other article is to assume the said block being
so constructed that it in the case of guttering first turns the lip-bead on the plate
which is to form the gutter prior to the plate being moulded or bent to its finished
form. The block is furnished with end journals which are supported in standards
or frames and which also support the end journals of the die, further said block
and die are so assembled that when a partial rotation is given to the block it over-
turns and passes to within the die. The die is also capable of a short radial
movement in order to allow a continuous pressure to be exerted on the plate whilst
the various members of the gutter are being moulded and for such purpose
said'
die is acted on by a weighted lever which forces it upwards against the pressure
exerted on it by the block when pressing the plate of sheet metal to its form. In
other words the block is so arranged that it closes into the die after the manner of
a hinge. Motion is given to the block by extending its journals beyond the
standards or frames far enough to receive spur wheels or partial spur wheels which
gear with pinions on a lay shaft and upon which shaft suitable gears are arranged
in order to give a reverse motion to the block when the guttering or other article
has been pressed to its form. To exert an upward pressure on the die a connecting
rod extends from its under side to a link a roller the link at its other end being
centred forward of the roller upon the frame of machine. Acting upon said
roller is a cam the path of which is of such a peculiar form as to exert its maximum
of pressure on the die as it is being pressed down by the block and a lesser
pressure as the block closes into the die. The said cam forms with a weighted
lever a sort of bell crank which is centred on a shaft supported by the said
standards or frames. To remove the guttering I provide an opening or gap in
either one or both of the standards or frames in order that the finished gutter may
be slid off the block endwise through one of said openings. Some descriptions of
guttering I strengthen by forming shallow transverse ribs, ridges or corrugations
at regular intervals upon it or such ridges may only be formed near its ends whilst
to produce them I form projections on the die and corresponding grooves or
recesses in the block.

other similar Articles.
I, ROBERT EDWARD EVENDEN, of "Heaton" North Coburg, in the Colony
of Victoria, 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 an improved machine for moulding or shaping guttering
or other similar articles from sheet metal plates. It consists of a horizontally
arranged pair of dies, or as they will be called hereinafter, a block and a dic, of
the requisite length and of the sectional shape or form which the guttering or
other articles is to take. The die is arranged between and supported by end
standards in such a manner as to have a very slight radial movement whilst the
block is carried by end journals also supported in said standards and in such a
manner that upon a partial rotation being given to said journals the block overturns
and passes to within the die so as to stamp or press the sheet of metal to the
requisite shape. When guttering is formed in the machine the lip-bead is turned
on the plate prior to the block entering the die to bring the plate to its finished
form and again to strengthen the guttering I may form shallow transverse ribs,
ridges or corrugations at regular intervals along its length or such ridges may be
only formed near its ends.
My invention will now be fully described aided by a reference to the accompanying
sheets of drawings in which,-
Fig. 1 is a transverse sectional view and
Fig. 2 a side view of the end part of machine and also shewing sufficient of its
length to illustrate the gears which control the dies.
and
Fig. 3 a plan of as much of the machine as is shewn in Fig. 2.
Fig. 4 an end view of the machine shewing the gears for overturning the block,
Fig. 5 a smaller view of a means for operating said gears.
A is the block and B the die, the surfaces a and b respectively of which are
shewn of such a form as to produce guttering. Block A is provided with end
journals A supported in bearings C1 in the frame C whilst the die B is carried
by a shaft B1 the end journals of which are supported in the blocks B 2 which
are arranged in suitable oblong holes or recesses in the standards C and are secured
therein by pinching screws B3. Block A has a bead a 1 on it to form the bead
of the guttering while the journal A 1 and bearing C1 have gaps in them in
order to allow the guttering when moulded to be slid out end wise through the
hole C2 formed in the standard C. Die B has a pin E carried by a lug bracket
on its back and upon said pin the upper eye of a connecting rod E is centred the
lower eye of which is centred on a pin E 2 carried at end of a pair of radius
links E3 which are centred on pin E4 carried by lugs upon a longitudinal plate G
the end flanges G 1 of which are bolted as shewn to the standards C. F is an arm
centred upon a pin F 1 and having a lever F 2 attached to it, the end of the latter
bearing a weight F 3. Arm F has an ear f on it which rests against the plate G
and also it has a sort of cam surface formed on it upon which a roller carried by
pin E2 bears. The object of the weighted arm gear is to provide such a support
for the die B as will allow it to yield radially when the pressure put upon it over-
comes the pressure exerted by the weighted lever. To impart motion to the
block A a broken spur pinion D is secured on its journal Al outside of the
standard C and such pinion is geared with a toothed reciprocating segmental
arm D1 which is centred at D2 on any suitable support and has motion imparted
to it by a rod D 4 centred on it at D 3 and deriving motion from a crauk disc D 5.

page_text: One or more of the weighted arm and lever gears E-F may be arranged along
the length of the die the number being regulated by its length between the
standards or frames and the nature of work it has to perform.
Although the block and die are shewn of such a shape and form as to produce
guttering I wish it to be understood that I do not confine myself only to employing
the machine for manufacturing guttering as by altering the block and die to suit
other sheet metal articles may be stamped or moulded in the machine and further
the actual working surfaces of both the block and die may be made in such a
manner as that they are capable of being taken off or removed from their
supporting bars, shafts or bearers as carried by aforesaid bearings A 1 and B 1
respectively and be replaced with a block and die shaped to press or mould other
articles.
When it is desired to strengthen the guttering by forming shallow transverse
ribs or corrugations on it a projecting rib b1 is formed on the die and a corre-
sponding recess a 2 in the block at the requisite position or positions, such ribs or
corrugations being as before stated either formed only near the end or ends of the
guttering or at regular intervals along its entire length.
In moulding guttering in the machine shewn, the sheet of metal of proper width
and length is first placed at the position indicated by the dotted line H and upon
motion being imparted to the spur pinion D the block A moves upon its axis in the
direction indicated by the arrow and in doing so first turns the bead upon the plate
and then as it proceeds in its revolution it gradually presses the plate down into
the die B until the block has taken its full travel, when it will be found that the
plate has been pressed between the dies or the block and die to the requisite shape
or form, the weighted lever gear E-F allowing the die to yield as the final
pressure is put upon the plate between the dies.
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 ;-
(1.) In a machine for moulding or shaping guttering and other similar articles a
block and a die each supported by independent journals in such a manner that the
block can overturn and close into the die substantially as herein described and
illustrated in my drawings.
(2.) In a machine for moulding or shaping guttering and other similar articles,
the combination of the block A having end journals A 1, the die B having end
journals B', the standards C one or both of which is provided with a cap C2 and
the gears marked El to E4 and F to F 3 substantially as herein described and
illustrated in my drawings.
(3.) In a machine for moulding or shaping guttering and other similar articles a
block as A baving a gap in its journal or journals and combined with a spur wheel
as D to which a to and fro partial rotation is imparted substantially as herein
described and illustrated in my drawings.
(4.) In a machine for moulding or shaping guttering transverse ribs and recesses
as a 2 and 1 formed in the surface of the block and die respectively in order to
strengthen the guttering substantially as herein described and as illustrated in my
drawings.
