New or Improved Dies or Appliances for making certain kinds of
Sewer Blocks, Drain Pipes, Conduits, Channel Blocks and the like.
We, JOSEPH HAMBLET, of Piercy Blue Buck, Tile and Pipe Works, West
Bromwich, in the County of Stafford, Blue Brick Tile and Pipe Manufacture,
and ISAAC PARKES, of 25, Bromford Lane, West Bromwich aforesaid, Foreman
d 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 consists of the herein described new or improved dies for
making those sewer blocks, drain pipes, conduits, channel blocks and the like
which are rebated down at one end so as to form a projecting spigot like part
which is adapted to fit into the open socket like end of the next sewer block
diain pipe, condunt, channel block on the like this spigot end being made of
the same shape in cross section as is the cross sectional shape of the sewer block
drain pipe conduit channel block or the like but smaller
The dies which form the subject of this invention are adapted for use with a
press or machine like that which is used for making spigot and socket dian
pipes in which the olay is forced through an annular die at the bottom of the
clay cylinder.
We will describe this invention by refering to the accompanying diawings

We will first refer more particularly to Figs 1 to 11 both inclusive and
describe this invention in connection with the manufacture of sewer blocks of
the kind represented by Figs. 1, 2 and 3 and marked A which sewer blocks are
of tubular form with closed ends, and when laid together end to end form the
base of the sewer, the sides of the sewer being built on and springing from the
two inclined sides a¹ as of the sewer block A which sides are sloped to the proper
angles and the top a³ of the sewer block is made hollow in a trough shape to
form the bottom of the interior of the sewer. A vertical strengthening rib a
runs along the sewer block from end to end. The said sewer blocks are flat at
the bottom a so as to lie evenly togethei Each of the sewer blocks is as
aforesaid rebated down at one end a", so as to form a projecting spigot like part
which is adapted to fit into the socket like end of the next sewer block
would here remark that when the sewer block in the green state is out off from
the dies which we are about to describe the socket end 18 open and the end part
of the centre 1b a has to be cut away and the flat clay filling up piece 8 has to
be moulded separately and inserted in the socket end of the sewer block to close
the end as shewn in Fig. 2
We
In carrying out this invention we provide at the bottom of the clay oylinder
which is provided with the paston C, a die plate E made with a hole e¹
coesponding with the cross sectional shape of the outside of the requned sewer
block A Within the dhe plate E we provide two blocks marked respectively F¹ F³
which as shown more clearly by Fig 9 are shaped to correspond with the
inter.or of the sewer block A the space f between these two blocks forming
the longitudinal vertical nb at which runs along the sewer block A from end
to end These two die blocks are espectively canied by the pins g¹ g
which are fixed to the bridges G G on the inside of the die plate E The
lower edges of the die blocks F1 F2 are champhered or channelled off
corresponding with the shape of the shoulders in the interior of the sewer block
at the commencement of the spigot part a. Carried on the usual 11sing and
falling table H underneath the die plates E we provide a bottom die I which has
a sunk recess contesponding in shape and size with the hole et in the die plate E
and has also within the recess another recess corresponding in shape and
size with the spigot end a of the required sewer block A. On the bottom
plate of the bottom die I there are two upwardly projecting pins ³ which are
made long enough to pierce the closed spigot end of the sewer block at a all 20
as to admit an into the interior of the same and prevent it collapsing whilst
the sewer block is being forced through the de These holes are afterwards
closed by clay plugs or left open
In forming the sewer block 1 by the dies or appliances above described the
Lottom die I is by the table H raised up against the bottom die plate E as
represented in Fig 4 We have not shewn the means for raising the table H
as such means are well known Also it will be understood that any convenient
means may be employed for locking the table H in its highest position such

page_text: for instance as the two armed lever made to clip and turn in a sunk
neck in the spindle h of the table H, these arma hh being made to turn
and engage with the two downwardly projecting hooked bars e e¹ fixed to the
bottom of the die plate E It is to be understood that the table H and the
means for locking it as described form no part of this invention.
After the table has been raised and locked in the position shewn by Fig. 4
the clay is then by the piston or plunger C of the machine forced through the die
plate E and into the recess if 13 of the bottom die I thus forming the spigot
end a of the sewer block The table H with the bottom die I upon it is then
lowered as shewn in Fig 5 which will leave the spigot end a of the clay sewer
block A projecting through the die plate E as shewn in Fig 5 A board J
having an opening of the proper shape and size to fit the spigot end as of the sewer
block 18 then placed under the shoulder of the sewer block to fit around the
apigot a so as to prevent the same from swelling out when the pressure is again
put on the piston C As the pressure on the clay in the cylinder is continued
the day is forced through the space el F between the hole in the die plate and the
two blocks F1 F2 and when sufficient has been forced through the die plate as
shewn in Fig 6 the sewer block A is cut off and the necessary holes a (Fig 1)
are made in the top part of the socket end of the sewer block A through which
to pour coment when making the joints of the sewer blocks as they lie together.
The portion of the centre rib which protrudes in the socket part is cut off
and the socket end a' is closed by the clay plate a as above described and the
sewer block is now trimmed ready for diying and buining.
This invention is similarly applied to the manufacture of drain pipes conduits
channel blocks and the like the opening in the die plate E and the die blocks
FF and also the recess in the bottom die I being made of the shape to
correspond with the particular drain pipe, conduit, channel block or the like
which is to be formed In some cases as for instance in making channel blocks
which are solid the die blocks F F are altogether dispensed with and in some
cases as for instance for drain pipes such as represented by Fig 20 only one die
block is employed as this article has no centre ib Moreover when the sewer
block conduit or the like has two or more longitudinal ribs one or more additional
die blocks such as F1 F must be used to correspond with the spaces between the
longitudinal bs of the sewer block conduit or the like.
It will be seen by an examination of Figs 12 14 and 16 that the die plate
and dies for making the conduit represented by Fig 13 are very similar to
those herein before described and illustrated by Figs 4, 5, 6, 7, 8, 9, 10 and 11
for making the sewer blocks represented by Figs 1, 2 and 3 It will be seen
that this conduit K 18 of rectangular form viewed endwise and has a central
longitudinal rib K³ ruuning from end to end but stopped off short at the socket
end the other end of the conduit having a short part to fit into the
corresponding socket end 8 of the next conduit The hole in the die plate E
Figs 12, 14 and 15 and the die blocks FF have to be of rectangular form
corresponding with the conduit as will readily be understood The bottom die
I is as shown in Figs 12 and 14 made of the proper size and shape to form the
spigot end and on the bottom plate 23 of the bottom die I there are two
upwardly projecting parts of rectangular form corresponding with the
openings of the conduit K and there is a space between these projections
The
to form the end portion of the central ib. Thus it will be seen by
Fig 12 that when the table 18 raised so that the bottom die I fits against the
underside of the die plate E and the clay is forced into the bottom die I the spigot
end and the end portion of the central rib are formed in this die I
table II with the die I is then lowered and the board J is placed round the
spigot end as shewn in Fig 14 to prevent the same from swelling and then
when the pressure is put on the piston C the clay is forced through the die
plate E as in Fig 15 and when sufficient has come through this is cut off forming
the conduit, but the socket end has then to be cut in by hand.

page_text: It will be seen by an examination of Tigs 16, 18 and 19 that the die and die
plates for making the channel block represented by Fig. 17 are also similar to
those above described except that as this channel block 18 solid the die
blocks FF2 are not required This channel block L is of the usual form except
that it has a short spigot part at one end which fits into a corresponding socket
paat at the end of the next channel block The hole in the die plate E 18,
as will be understood, made to correspond with the exterior shape of the channel
block L and the recess of the bottom die I is made to collespond with the
shape and size of the opening e' of the die plate E and the other recess an
the bottom die I is made to form the spigot part of the channel block L The
operation of forming the channel block requires no description as it is similai to
that above descubed with reference to making the sewei blocks and conduits.
It will be understood that the socket pait has to be cut into the channel
block L by hand after the channel block has been cut off from the die plate E.
It will be understood that the die plate and dies can be similarly formed for
making the conduit represented by Figs 21 and 22 which is one of the kind in
which the upper part M¹ is made in the form of a cover separate from the lower
part M³ the latter having a projecting hip m² m² at each side forming a rebate
to receive the lid M' The hid and the lower pait M³ are both rebated down
at one end so as to form a spigot part m³ which fits into the corresponding socket
part m in the next conduit In making this conduit the lid M¹ is made separate
from the bottom part 2 the hole el in the die plates E being made to correspond
with the coas sectional shape of the lid M' oi of the bottom pait M and the
bottom dies being made with a iccess as above described so as to form the
spigot part m³.
The accompanying diawings illustrate what we consider to be the best ways
of carving our invention into practice but it will be understood that our
invention is not limited to the precise details shewn as the shape of the die and
die plate, and of the die block or blocks when used, will have to be varied
according to the cross sectional shape of the sewer block, drain pipe, conduit,
channel block on the hike, which is to be produced
