PROVISIONAL SPECIFICATION.
Improvements in or connected with Apparatus or Machinery for
Moulding and Pressing Seeds and other Substances or Products.
We WILLIAM BUSHELL and WALTER THOMAS HAYDON both of Dover in the
County of Kent, Engineers, do hereby declare the nature of this invention to be as
follows:-
This invention refers to apparatus for moulding into a form or shape and pressing
or partially pressing such substances as seeds, corn, meal, or other products, and the
said invention is especially adapted to be employed in conjunction with such
machinery or apparatus as is described in the Specification of patent granted to us
and dated 2nd October 1882 No. 4686.
According to our invention we mount upon a vertical shaft a revolving table, and
when there are three operations to take place simultaneously there are three apertures
formed in the said table, the apertures being preferably somewhat smaller in plan
than the press in which a final pressure is to be given and the said table is inter-
mittently revolved one third of a revolution at a time, by means of cams, friction-
clutches, or other suitable means. The apertures through the table are of a suitable
and predetermined depth, so as to be of a known capacity for containing whatever
substances are to be moulded and pressed (hereafter in this specification termed the
"material") and it is in these apertures (hereinafter called "moulds.") that the
material is pressed.
"
It being necessary or desirable to separate the cakes by means of a metal plate and
a piece of woollen cloth when receiving an after or final pressure, the said plates are
inserted according to our invention into each of the said moulds consecutively
(during the intermittent stoppages of the table) by an automatic device which we
term a tilting table
and the said plates are received one by one into recesses or
annular spaces in the bottom of the moulds and are kept therein by means of a
supporting table, upon which the plates rest and slide during their passage from the
"tilting table to the pressing disc, and the plate forms a bottom to the mould to
receive the "material," and the cloth is then inserted by hand.
"
The inner end of the tilting table is arranged so as to be immediately under one of
the moulds when the table is intermittently stopped, which occurs as aforesaid every
third of a revolution. The other outer end of the tilting table projects sufficiently and
when in a horizontal position receives one of the metal plates the tilting table (which.
is actuated by means of a crank and a combination of links and levers) then moves
from the horizontal position and causes the plate by gravity to slide to the inner end
under the mould and the next upward motion of the inner end of the tilting table
inserts the plate into the recess in the bottom of the mould where it remains until
the mould revolving carries it on to the supporting table. This insertion of a plate
occurs three times for every revolution of the table suitable means being provided
for stopping and securing the said table, during which stoppage the three moulds are
being acted upon simultaneously so that each mould during one revolution is firstly
provided with a plate and cloth, secondly filled with material and if necessary another
plate and bag put on, and thirdly the material is pressed, ejected from the mould and
carried away all as hereafter described.
The moulds are supplied with material from a feed box which is in connection with
a "kettle" holding the material, a sufficient quantity of the latter being drawn off
into the feed box and the aperture in the kettle is then closed. The feed box is
slidden from beneath the kettle to the top of that mould which is next to the mould
in which a plate is being inserted, thus the top of the feed box receives the material
from the kettle and the bottom of the feed box slides over the mould and delivers its

page_text: contents which fall by gravity through a sliding door in the feed box which door may
be automatically operated.
The feed box is operated by mechanical means, by for example a lever actuated by
a cam which while the feed box is over the mould communicates to it a shaking
motion in order. to evenly distribute the material in the mould.
After the filling or feeding of the mould the next partial revolution and stoppage
of the table brings the particular mould in question under the action of the pressing and
ejecting devices which we will now describe while at the same time an empty mould
is presented to the tilting table to be supplied with a plate and " bag" and a mould
with a plate and "bag" or cloth is presented to the material supplying device.
The
According to our invention the pressing devices are arranged and act as follows
when the table is stopped one of the moulds is in such position that it has situated
directly above it a flat disc of the same shape and dimensions as the mould, a similar
disc being directly beneath the said mould. These upper and lower discs are suitably
mounted and receive certain relative motions as hereafter described from cams.
upper disc remains at rest above the table a sufficient time to allow the table to
revolve one third of a revolution while during the latter portion of which time the
lower disc is at rest at the level of the bottom of the mould or table ready to receive
the plate and " bag from the supporting table, the act of revolving causing the
plate to rest then on the lower disc. The upper disc is then caused to descend
rapidly until it reaches the material and slightly presses it, and the speed of the
descent is now gradually decreased until the material is sufficiently compressed
during the whole of which operation the lower disc remains stationary.
"
The upper disc is now caused to continue its descent at an increased speed and to
push the pressed material and the plate and "bag" (or the plates and bags) through
the bottoin of the mould the lower disc allowing of this action by being dropped
to a lower level; the upper disc then rises very rapidly to its first position leaving the
cake resting on the lower disc.
The "table" is now free to revolve another third of a revolution during which the
cake or moulded material is removed by means of a bent arm or lever which
sweeping over the surface of the bottom disc carries with it the moulded material,
depositing it on a fixed table or shelf suitably placed to receive it, from here it may
be removed by hand or any suitable mechanical device. The bent arin having
discharged the moulded material returns to its original position ready to remove
another cake. Motion is given to this bent arm by means of a cam and levers.
After the discharge of a cake the lower disc is caused to rise rapidly to its first
position.
The cycle of motions as above described is then repeated and when used in
conjunction with our patented invention herein referred to, the partially pressed and
moulded cakes are inserted or dropped into the press therein described or into other
suitable press and there receive their final or finishing pressure.

COMPLETE SPECIFICATION.
Improvements in or connected with Apparatus or Machinery for
Moulding and Pressing Seeds and other Substances or Products.
We, WILLIAM BUSHELL and WALTER THOMAS HAYDON both of Dover in the
County of Kent, Engineers 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 refers to apparatus for moulding into a form or shape and pressing
or partially pressing such substances as seeds, corn, meal or other products, and the

page_text: said invention is especially adapted to be employed in conjunction with such
machinery or apparatus as is described in the Specification of patent granted to us
and dated 2nd October 1882 No. 4686.
In order that our invention may be clearly understood we will describe the same
with reference to the accompanying drawings on which similar letters of reference
refer to like parts in the various figures. Figures 1 to 4 show our machine or
apparatus, or so much of same as is necessary for the purposes of this specification
the figures 5 to 23 inclusive being drawings of detached parts or details of the
machinery, and Figure 24 is a perspective front view of the machine.
Figure 1 is a front elevation, Figure 2 a left hand side elevation, Figure 3 a
partial sectional plan, and Figure 4 a right hand sectional side elevation.
According to our invention we mount in bearings provided in framework A of the
machine a vertical shaft B Figure 4 and key thereon a table C. When there are
three operations to take place synchronously there are three apertures ("¹ Figure 3
formed in the said table C the apertures being preferably somewhat smaller in
plan than the press, such for example as that described in the specification of patent
No. 4686 herein before referred to, in which a final pressure is to be given and the
said table C is intermittently revolved one third of a revolution at a time as hereafter
described.
The mechanism whereby the table C receives its intermittent motion is arranged as
follows: G Figures 1 and 3 is the driving shaft of the machine provided with fly
wheel G' and fast and loose pulleys G. Keyed to the shaft G is a pinion G³ gearing
with spur
wheel H' Figures 1 and 4 on shaft H. On the inner extremity of shaft H
there is a bevil wheel H clearly shown at Figures 7 and 8 which are respectively
partial plan and vertical section showing the mechanism for revolving the table C.
The bevel wheel H' gears into bevil wheel J on a vertical spindle J' to which latter is
keyed a pinion J2 gearing with spur wheel B¹ which is loosely mounted on shaft B to
which the table C is keyed as aforesaid. K is a drum keyed to shaft B, and K' is a
strap or band (termed the friction band) made in two or more sections, the sections
being united by means of bolts with springs inserted beneath the nuts, thus giving
facilities for adjustment such a friction band K' is shown detached in plan below
Figure 8. Projecting from the friction band are two or more lugs K' engaging with
the spur wheel B¹.
The spur wheel B¹ driven by the pinion J is continuously revolving, carrying with
it the friction band K' which latter is adjusted so as to be sufficiently tight to cause
the shaft B with the attached table C to revolve when the table C is not engaged by
the bolt F hereafter described. When the table C is engaged by the bolt F the
friction band slips around the drum K at the same time being sufficiently tight to
again revolve the table immediately the bolt F is withdrawn.
This table C, which we form circular in plan, is shown separately and drawn to a
larger scale at Figures 11 to 14, Figure 11 being a plan, Figure 12 a vertical section
Figure 13 an inverted plan, and Figure 14 a cross section on the line X Y of
Figure 13.
The apertures C¹ through the table Care of a suitable and predetermined depth as
will be observed by reference to Figures 12 and 14 so as to be of a known capacity
for containing whatever substances are to be moulded and pressed (hereafter in this
Specification termed the "material") and it is in these apertures (hereinafter
called "moulds") that the material is pressed. Plates and cloths are inserted into
each of the said moulds consecutively during the intermittent stoppages of the table C;"
by an automatic device, which we term a tilting table," and it being necessary or
desirable to separate the cakes by means of a metal plate and a piece of woollen
cloth when receiving an after or final pressure, the same plates may be then
employed.
66
The said plates which are circular in plan are inserted one by one into recesses or
annular spaces C Figures 13 and 14 in the bottom of the moulds C¹.
D indicates the tilting table Figures 1, 2 and 3, mounted on trunnions D¹ D'
Figure 3 on the left hand side of the framework.

page_text: The inner end of the tilting table D is arranged, so as to be immediately under one
of the moulds (when the table is intermittently stopped which occurs as aforesaid
every third of a revolution; the other outer end of the tilting table D projects
sufficiently and when in a horizontal position receives by hand for example one of the
metal plates.
The tilting table is rocked at proper intervals from a horizontal position, or nearly
so, to an inclined position as at Figures 1 and 2 and causes the plate to slide by
gravity along the slides D' to the inner end of the tilting table D, under the mould
where it is stopped by projecting stops D³.
The rocking of the table D is effected in the following manner: on the shaft H
Figure 4 is keyed a pinion H gearing with a spur wheel L¹, on shaft L, mounted in
bearings at the lower part of the machine. At the opposite end of the shaft L there
is a crank M Figures 1 and 2 provided with connecting rod M' the other end of
which is slotted and takes onto and operates a bellcrank lever M³ the other arm of
which by connecting rod M³ operates the tilting table D. The slot in the connecting
rod M¹ gives sufficient lost motion to allow, for the pause or rest of the tilting table
in its two positions.
The tilting table being in its inclined position and the plate resting against the
stops D' the next upward motion of the inner end of the tilting table D inserts the
plate into the recess in the bottom of the mould, and a cloth is dropped on same
by band the cloth and plate remaining there, until the mould C revolving, carries the
plate and cloth onto a supporting table (which is fixed to the framework A and
extends closely underneath the table C, and as the table C revolves the plate is
carried or supported by the aforesaid supporting table (x. This insertion of a plate
occurs three times for every revolution of the table C, suitable means being provided
for stopping and securing the said table, such for example as the following. Mounted
in bearings in the upper part of the framework and vertically above the shaft L, there
is a shaft E, which latter receives continuous rotatory motion from the shaft L by
spur wheel L', gearing with spur wheel N, loosely mounted on stud bearings on frame-
work A, which wheel N gears with spur wheel E¹ keyed to shaft E.
Keyed on the shaft E, there is a cam F which acts on a weighted lever arm F¹
Figures 1 and 24, one end of which lever arm F¹ is pivotted to the framework of the
machine and from the front end, as seen at Figure 1, there is a connecting rod F' to
a bolt F³, capable of being slidden in bearings on the framework of the machine, and
the cam is so shaped that at every third of a revolution made by the table ( the
bolt F is allowed to descend, and to enter one of three holes F Figure 3, made in
the table C, and retains the same in position during the necessary space of time;
The frictional driving device allowing of the table being thus stopped, and on the
bolt F being withdrawn, by the action of the cam F, the rotation of the table C
proceeds. During this stoppage the three moulds are being acted upon synchronously
so that each mould during one revolution is firstly provided with a plate and cloth, by
means of the tilting table D, secondly filled with material, when if necessary another
plate and bag are put on by hand or otherwise, and thirdly the material is pressed,
ejected from the mould, and carried away, all as hereafter described.
The moulds are supplied with material from a feed box, which is in connection with
akettle" P the position of which is indicated at Figure 4, and which contains
"the material" the latter being admitted from the said kettle P to a hopper P'. The
lower part or mouth of the hopper P₁ is closed by a plate P³, which is capable of
being slidden in grooves or guides therein, and towards the inner end of the plate P'
is fixed the feed box P'. The feed box and plate P P are reciprocated at the proper
times in the following manner; towards the right hand end of the shaft E we provide
a grooved cam R, in the groove of which there is a bowl, carried by a link S shown
in the general view at Figure 4, and more fully on a larger scale at Figures 5 and 6,
these being respectively side elevation and partial horizontal section. One end of the
link S is carried by link S¹, not shown at Figure 6, which swings from a bearing
pin Sx, on the framework A, while the other end of the link S is pivotted to a
lever S³, also fulcrummed to the framework, and its lower end is connected to the

page_text: feed box P' by a connecting rod S³. When the feed box P' is slidden beneath the
hopper P', it will become filled with "material," and when drawn away the hopper
will be closed by the plate P'. The feed box P³ being filled, is slidden from beneath
the hopper P¹ to the top of that mould C, which is next to the mould in which a
plate is being inserted, thus the top of the hopper P¹ receives the material from the
kettle P, and the bottom of the feed box slides over the mould (" and delivers its
contents which fall by gravity. In some cases a sliding door may be provided in the
feed box, which door may be automatically operated, although in the example shown,
the feed box P travels over the surface of a fixed plate P, which closes the bottom
of the said box.
The feed box may, if found necessary, be actuated, for example by levers and cams
which while the said feed box is over the mould communicates to it a shaking motion
in order to evenly distribute the material in the mould although in the machine shown
this has been considered unnecessary.
After the filling or feeding of the mould, the next partial revolution and stoppage of
the table, brings the particular mould in question under the action of the pressing and
ejecting devices, which we will now describe, while at the same time an empty
mould is presented to the tilting table D, to be supplied with a plate and "bag," and a
mould with a plate and "bag" or cloth, is presented to the material-supplying device.
According to our invention, the pressing devices are arranged and act as follows:
when the table C is stopped, one of the moulds C, is in such position that it has
situated directly above it a flat disc T, such as are shown at Figures 21, 22 and 23
which are respectively elevation, plan and vertical section, the disc being of the
same shape in plan and dimensions as the mould, a similar disc U being directly
beneath the said mould. These upper and lower.pressing discs T U, are mounted.. on
shafts T U¹, which are free to rise and fall vertically in bearings provided on the
framework Á. The lower end of the shaft U', rests on a cam U mounted on the
rotative shaft L, such a cam U is shown in elevation and section respectively at
Figures 9 and 10. The upper disc and shaft T T', is lifted as will be observed by
reference to Figure 1, by means of link V, lever V and counterbalance arm and
weight respectively marked V V. By this counterbalance device the shaft T' is
brought to bear against, and follow a cam T2 mounted on the rotative shaft.E; such
a cam T' is shown in elevation and section respectively at Figures 15 and 16.
:
The upper disc T is caused to rest, above the table C, a sufficient time to allow the
said table to revolve one-third of a revolution, while during the latter portion of
which time, the lower disc U is at rest, at the same level as the bottom of the table C,
ready to receive and support the plate and "bag" from the supporting table C×,
the revolving of the table C causing the plate to rest then on the lower disc. U.
The upper disc T is then caused to descend rapidly, until it reaches the material and
slightly presses it, and the speed of the descent is now gradually decreased, until the
material is sufficiently compressed, during the whole of which operation the lower
disc U reinains stationary.
The upper disc T is now caused to continue its descent at an increased speed, and
to push the pressed material and the plate and "bag" (or the plates and bags) through
the bottom of the mould, the lower disc U allowing of this action by being dropped
to a lower level; the upper disc T then rises very rapidly to its first position, leaving
the cake resting on the lower disc.
The "table"C is now free to revolve another third of a revolution, during which
the cake or moulded material is removed, by means of a bent arm or lever W, shown
detached in elevation and plan respectively at Figures 17 and 18. This bent arm W
sweeps over the surface of the bottom disc U, and carries with it the moulded
material depositing it on a fixed table or shelf or other receptacle suitably placed to
receive it; from here it may be removed by hand or any suitable mechanical device.
The bent arm W having discharged the moulded material returns to its origina
position, ready to remove another cake. Motion is given to this bent arm by the
following means.
The bent arm W is keyed on a vertical spindle W₁, the latter having bearings on

page_text: the framework A. On the lower end of the spindle W₁, there is fixed an arm W³,
and this arm is acted upon by a cam W³, on the shaft L; such a cam W is shown
detached at Figures 19 and 20 in elevation and section respectively. . The arm W
may be held to the cam by means of a spring, for example attached by the bolt W**
to the arm W, and the other end to a suitable part of the framework.
Figure 24 is a perspective front view of the machine.
After the discharge of a cake the lower disc is caused to rise rapidly to its first
position.
The cycle of motions as above described is then repeated, and when used in con-
junction with our patented invention herein referred to, the partially pressed and
moulded cakes are inserted or dropped into the press therein described, or into other
suitable press and there receive their final or finishing pressure.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare. that what we
claim is :-
