An Improved Method of and Apparatus for Manufacturing Gullies,
Traps, Syphons, and other Sanitary Ware.
We, EDMUND JOSEPH JEFFCOTE, Engineer, of "The Yews," Coton Road, and
JAMES BATES, Brickyard Proprietor, of Manor Court Road, both in Nuneaton, in
the County of Warwick, do hereby declare the nature of this invention to be as
follows:-
:-
Our invention consists in an Improved Method of and Apparatus for Manufac-
turing Gullies, Traps, Syphons and other Sanitary Ware.
Hitherto a gulley, trap, syphon or similar article has been made in parts and
subsequently joined together by hand-a tedious and costly process.
The objects of the present invention are, first, to produce, in one piece without
join, an article of the kind referred to; secondly, to reduce the cost of manufacture;
and, thirdly; to improve the quality of the ware.
In carrying out this invention, we prefer to employ a mould or matrix divided in
a horizontal plane. The interior of the divided mould corresponds with the
exterior of the gulley or other article to be manufactured. Within the mould is
placed a box core, and also a bend core in sections connected to the box core.
The exterior of the united box and bend cores corresponds with the interior of the
gulley or other article. The bend core is usually in three sections; these being
secured to one another and to the box core by a removable pin furnished with a
handle. The box core has a spindle whereby it is supported in the mould. This
spindle projects through a hole, half of which is in one part of the mould and the
other half in the other part. The extremity of the spindle has two collars adapted
to fit one on each side of a jaw projecting from the lower part of the mould.
order to keep the spindle in position, a bolt is passed through two holes in the jaw;
the central portion of the bolt bearing against the top of the spindle. It is,
however, obvious that other means may be used for holding the box core.
divided mould, at the opposite end to that whereat the spindle projects, has a
flanged inlet passage; the flange enabling the mould to be attached to the feed of
a machine. The clay is forced from the machine through the inlet into the space
between the mould and the cores. The core spindle is then released, the mould
divided, the pin withdrawn, the box core removed and the bend core taken out
section by section.

An Improved Method of and Apparatus for Manufacturing Gullies,
Traps, Syphons, and other Sanitary Ware.
We, EDMUND JOSEPH JEFFCOTE, Engineer, of "The Yews," Coton Road, and
JAMES BATES, Brickyard Proprietor, of Manor Court Road, both in Nuneaton, in
the County of Warwick, 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 :-―
Our invention consists in an Improved Method of and Apparatus for Manufac-
turing Gullies, Traps, Syphons and other Sanitary Ware.

page_text: Hitherto a gulley, trap, syphon or similar article has been made in parts and
subsequently joined together by hand-a tedious and costly process.
The objects of the present invention are, first, to produce, in one piece without
join, an article of the kind referred to; secondly, to reduce the cost of manufacture;
and, thirdly, to improve the quality of the ware.
In the accompanying drawings,
Fig. 1 is a diagram representing in side elevation the lower half of a divided
mould or matrix provided with horizontal connected cores and appurtenances
adapted for use in carrying out our improved method.
Fig. 2 is a corresponding view of the upper half of the divided mould or matrix.
Fig. 3 is a plan corresponding with Fig. 1.
Fig. 4 is a plan of the connected cores.
Fig. 5 is a side elevation of apparatus embodying a divided mould or matrix and
connected cores; the cores being arranged vertically instead of horizontally.
Fig. 6 is a corresponding front elevation.
Fig. 7 is a plan corresponding with the upper portion of Figs. 5 and 6 and
showing the divided mould and accessory parts mounted on the under side of a
plate bolted to the feed of a machine whereby clay is forced between the mould
and the cores.
In carrying out this invention according to the manner illustrated diagrammatically
in Figs.
to 4, we employ a mould or matrix A A' divided longitudinally in a
horizontal plane. The interior of the divided mould corresponds with the exterior
of the gulley or other article to be manufactured. Within the mould is placed a
box core B, and also a bend core C C C in sections connected to the box core.
The exterior of the united box and bend cores corresponds with the interior of the
gulley or other article. The bend core is usually in three sections, as shown;
these being secured to one another and to the box core by a removable pin D
formed with a handle D¹. The box core has a spindle B¹ whereby it is supported
in the mould. This spindle projects through a hole, half of which is in the part A
of the mould and the other half in the part A¹. The extremity of the spindle B'
has two collars B and B adapted to fit one on each side of a jaw E projecting
from the part A of the mould. In order to keep the spindle in position, a bolt F F
may be passed through two holes in the jaw; the central portion of the bolt
bearing against the top of the spindle between the collars. The divided mould or
matrix A A' has a flanged inlet A'; the flange enabling the mould or matrix to be
attached to the feed of any suitable machine. It will be understood that the
parts A and A' are, prior to the admission of clay, bolted or otherwise secured
together in any suitable manner.
The clay is forced from the feeding machine through the inlet A' into the space
between the mould A A' and the cores B and C CC. The spindle B' is then
released by removing the pin F F¹, and the parts A and A' are disconnected. The
part A¹ having been lifted, the pin D is pulled out, the box core B removel and
the bend core C C¹ C' taken away section by section-first the section C or C³,
then the section Cor C and finally the section C¹; the section C' being withdrawn
through the space originally occupied by the box core B. Each section of the
bend core may be provided with a small handle which in its normal position lies
folded down flush; the handle facilitating the withdrawal of the section.
In Figs. 5, 6 and 7, the divided mould or matrix and the cores are placed
vertically instead of horizontally. The two halves A and A' of the longitudinally
divided mould or matrix are mounted to slide on a plate N° which is bolted to the
feed A' of any suitable machine capable of forcing clay into the space between the
divided mould or matrix and the connected cores B and CCC* C. The additional
section C* enables the bend core to be more easily taken away piece by piece than
when that core comprises three sections only. The core B is secured to a plate B*
mounted on a flange at the top of a sliding shaft G, which may be hollow, as
shown. This shaft is arranged to slide vertically in a bearing H provided in a
cross piece H¹. A jaw Ex may be bolted to the plate B*; a pin F F passing

page_text: through the sides of the jaw and through a hole in the pin D D¹. The shaft G
with the cores B and C C C C and their appurtenances are counterbalanced by
weights I connected to the bottom of the shaft G by bands, ropes or chains .J
passing over pulleys K mounted in brackets bolted to the cross piece H. The
shaft G and cores B and C C₁ C* C² are represented in their lowest position..
They are raised into their working position by the pressure of the attendant's hand.
placed under the plate B*, and are lockel in that position by two dogs L which:
engage in holes G* in the shaft G. Both dogs are caused to approach one another
or to recede simultaneously by moving the hand-lever M, which causes the shafts M
and M², owing to the manner in which they are connected, to rock in opposite
directions; these shafts being furnished with arms coupled by a link M. The-
dogs L are coupled by links M with arms M' on the shafts M' and M'. The
parts A and A' of the mould or matrix, are brought toward or away from one
another by moving the hand-lever N, which rocks the shafts N' and N in opposite-
directions; an arm N³ on the shaft N¹ being connected to an arm N on the-
shaft N' by a link N°. The part A¹ is coupled to an arm N' on the shaft N1 by a.
link N the part A being coupled to an arm N' on the shaft N' by a link N..
The rocking shafts N₁ and N' are supported in brackets N* bolted to the plate N°..
If preferred, the brackets N* and the plate N° may be cast in one piece. O and O¹
are guides between which the parts A and A' slide. The latter are held together
by catches P and P₁ pivoted to the part A' and engaging with snugs on the part A,
and by a hook P' also pivoted to the part A¹ and engaging with a snug P* on the
part A. The plates Q and Q' form removable sides to the cavity of the mould;:
the withdrawal of these plates facilitating the removal of the raw gulley. The
sliding and connected bars R and R' carry a wire for cutting off the feed.
The action is as follows:-The cores B and C C₁ C* C* having been raised into
their highest or working position, the lever M is moved until the dogs L engage in
the holes G. The lever N is then actuated in order to bring the parts A and A¹.
together, whereupon the plates Q and Q' are inserted, the catches P and P¹ caused.
to engage with their snugs, and the hook P' is forced over the snug P³. Pins S.
and S', which are carried in lugs on the parts A. and A', are then pressed into-
holes made for their reception in the plate B*; the divided mould or matrix being
thus securely held. Clay is thereupon forced through the inlet passage (A') into.
the space between the divided mould A A', the plates Q and Q1 and the cores B
and C C¹ C* C². After that space has been filled, the feed is stopped; the clay
being cut off with the wire carried by the bars R and R'. The pin F' F' having
been pulled out and the pin D D' removed, the catches P and P₁ and the hook 1:
are turned out of engagement and the plates Q and Q₁ withdrawn. The lever M
is then actuated so as to take the dogs L and L₁ out of the holes Gx. The core B.
is then removed by pressing down the shaft G and the parts mounted thereon into
the position shown in Figs. 5 and 6. The core C C¹ C* C is then taken out.
